Can now parse timeclock files. These are simple timelogs that track
in/out events, which can be maintained using my timeclock tool. By
allowing ledger to parse these, it means that reporting can be done
on them in the same way as a ledger file (the commodities is "h",
for hours); and it means that doing things like tracking billable
hours for clients, and invoicing those clients to transfer those
hours into a dollar value via a receivable account, is now trivial.
See the docs for more on how to do this.

#title Ledger: Command-Line Accounting
<contents>
* Building
* Introduction
Welcome to ledger, a command-line accounting program that uses a
text-based ledger file, yet provides full double-entry accounting, use
of commodities, unlimited accounts, etc.
Ledger is an accounting tool with the moxie to exist. It provides no
bells or whistles, and returns the user to the days before user
interfaces were even a twinkling in their father's CRT.
What it does do is to offer a double-entry accounting ledger with all
the flexibility and muscle of its modern day cousins, without any of
the fat. Think of it as the Great Bran Muffin of accounting tools.
To use it, you need to start keeping a ledger. This is the basis of
all accounting, and if you haven't started yet, now is the time to
learn. The little booklet that comes with your checkbook is a ledger,
so we'll describe double-entry accounting in terms of that.
A checkbook ledger records debits (subtractions, or withdrawals) and
credits (additions, or deposits) with reference to a single account:
the checking account. Where the money comes from, and where it goes
to, are described in the payee field, where you write the person or
company's name. The ultimate aim of keeping a checkbook ledger is to
know how much money is available to spend. That's really the aim of
all ledgers.
What computers add is the ability to walk through these transactions,
and tell you things about your spending habits; to let you devise
budgets and get control over your spending; to squirrel away money
into virtual savings account without having to physically move money
around; etc. As you keep your ledger, you are recording information
about your life and habits, and sometimes that information can start
telling you things you aren't aware of. Such is the aim of all good
accounting tools.
The next step up from a checkbook ledger, is a ledger that keeps track
of all your accounts, not just checking. In such a ledger, you record
not only who gets paid -- in the case of a debit -- but where the
money came from. In a checkbook ledger, its assumed that all the
money comes from your checking account. But in a general ledger, you
write transaction two-lines: The source account and target account.
*There must always be a debit from at least one account for every
credit made to another account*. This is what is meant by
"double-entry" accounting: the ledger must always balance to zero,
with an equal number of debits and credits.
For example, let's say you have a checking account and a brokerage
account, and you can write checks from both of them. Rather than keep
two checkbooks, you decide to use one ledger for both. In this
general ledger you need to record a payment to Pacific Bell for your
monthly phone bill. The cost is $23.00, let's say, and you want to
pay it from your checking account. In the general ledger you need to
say where the money came from, in addition to where it's going to.
The entry might look like this:
<example>
9/29 BAL Pacific Bell $200.00 $200.00
Equity:Opening Balances $-200.00
9/29 BAL Checking $100.00 $100.00
Equity:Opening Balances $-100.00
9/29 100 Pacific Bell $23.00 $223.00
Checking $-23.00 $77.00
</example>
The first line shows a credit (or payment) to Pacific Bell for $23.00.
Because there is no "balance" in a general ledger -- it's always zero
-- we write in the total balance of all payments to "Pacific Bell",
which now is $223.00 (previously the balance was $200.00). This is
done by looking at the last entry for "Pacific Bell" in the ledger,
adding $23.00 to that amount, and writing the total in the balance
column. And the money came from "Checking" -- a debit (or withdrawal)
of $23.00 -- which leaves the ending balance in "Checking" at $77.00.
This is a very manual procedure; but that's where computers come in...
The transaction must balance to $0: $23 went to Pacific Bell, $23 came
from Checking. There is nothing left over to be accounted for, since
the money has simply moved from one account to another. This is the
basis of double-entry accounting: that money never pops in or out of
existence; it is always a transaction from one account to another.
Keeping a general ledger is the same as keeping two separate ledgers:
One for Pacific Bell and one for Checking. In that case, each time a
credit is written into one, you write a corresponding debit into the
other. This makes it easier to write in a "running balance", since
you don't have to look back at the last time the account was
referenced -- but it also means having a lot of ledger books, if you
deal with multiple accounts.
Enter the beauty of computerized accounting. The purpose of the
Ledger program is to make general ledger accounting simple, by keeping
track of the balances for you. Your only job is to enter the
credit/debit transactions. If a transaction does not balance, Ledger
will display an error and indicate which transaction is wrong.[1]
In summary, there are two aspects of Ledger use: Updating the ledger
data file, and using the Ledger tool to view the summarized result of
your entries.
* Building the program
Ledger is written in ANSI C++, and should compile on any platform. It
only depends on the GNU multiprecision integer library (gmp, or
libgmp), and the Perl regular expression library (pcre, or libpcre).
Also, this project was developed using GNU make and gcc 3.3.

* Introduction
Ledger is an accounting tool with the moxie to exist. It provides not
one bell or whistle for the money, and returns the user to the days
before user interfaces were even a twinkle in their father's CRT.
What it does do is provide a double-entry accounting ledger with all
of the flexibility and muscle of its modern day cousins -- without any
of the fat. Think of it as the bran muffin of accounting tools.
To begin with, you need to start keeping a ledger. This is the basis
of all accounting, and if you don't know how to do it, now is the time
to learn. The little booklet that comes with your checkbook is a
ledger, so we'll describe double-entry accounting in terms of that.
A checkbook ledger records debits (subtractions, or withdrawals) and
credits (additions, or deposits) with reference to a single account:
your checking account. Where the money comes from, and where it goes
to, are simply described in the memo field where you write the person
or the company's name. The ultimate aim of keeping a checkbook ledger
is so you know how much money is available to spend at all times.
That is really the aim of all ledgers.
What computers add is the ability to walk through all of those
transactions and tell you things about your spending habits; let you
devise budgets to get control over your spending; squirrel away money
into virtual savings account without having to physically move the
money around; etc. As you keep your checkbook ledger, you are
recording a lot of information about your life and your habits, and
sometimes that information can tell you things you aren't even aware
of. That is the aim of all good accounting tools.
The next step up from a checkbook ledger is a ledger that covers all
of your accounts, not just your checking account. In this ledger, you
write not only who the money goes to -- in the case of a debit -- but
where the money is coming from. In the checkbook ledger, its assumed
that all of the money is coming from your checking account. But in a
general ledger, you have to write two-lines: The source and target.
There must always be a debit from some account for any credit made to
anyone else. This is what is meant by "double-entry" accounting.
For example, let's say you have a checking account and a brokerage
account, and that you can write checks from both of them. Rather than
keeping two checkbooks, you decide to use one ledger for both. Once
you get the hang of this, you'll be ready to use one ledger for all of
your accounting needs, which gets you to the point of this
introduction.
So in your general ledger, you need to pay Pacific Bell Telephone for
your monthly phone bill. The cost is $23.00. In a checkbook ledger,
you would write out a line that credits your account with Pacific Bell
by $23 as follows:
<example>
9/29 100 Pacific Bell $23.00 $77.00
</example>
Very simple: You've written check #100 for $23 to Pacific Bell, which
leaves your balance in checking at $77.
But in a general ledger, you need to say where the money is coming
from. A general ledger entry would look like this:
<example>
9/29 100 Pacific Bell $23.00 $223.00
Checking $-23.00 $77.00
</example>
What does all of this mean? The first line shows a credit (or
payment) to Pacific Bell to the tune of $23.00. Then, because there
is no one "balance" in a general ledger, we've written in the total
balance of your payments to the account "Pacific Bell". This was done
by looking at the last entry for "Pacific Bell" in the general ledger,
adding $23.00 to that amount, and writing in the total in the balance
column.
Secondly, the money is coming from your "Checking" account, which
means a debit (or withdrawal) of $23.00, which will leave the ending
balance in your "Checking" account at $77.00.
The transaction itself must balance to $0: $23 goes to Pacific Bell,
$23 comes from Checking: there is nothing left over to be accounted
for. The money has in fact moved from one account to another. This
is basis of double-entry accounting: That money never pops out of
existence, it is always described as a transaction between accounts --
as a flow from one place to another.
Keeping a general ledger is the same as keeping two separate ledgers:
One for Pacific Bell and one for Checking. In that case, each time
you write a credit into one, you write a corresponding debit into the
other. This makes it much easier to write in the running balance,
since you don't have to go looking back for the last time an account
was referenced, but it also means having a lot of ledger books if you
deal with multiple accounts.
Enter the beauty of a computerized accounting tool. The purpose of
Ledger is to make general ledger accounting simple by keeping track of
the balances for you. Your only job is to enter credit/debit pairs
and make sure they balance. If a transaction does not balance, Ledger
will display an error and ignore the transaction.[1]
Your usage of Ledger will have two parts: Keeping the ledger, and
using the Ledger tool to provide you with information summaries
derived from your ledger's entries.

* Using the Ledger Tool
** Dealing with cash
Now that you have an orderly and well-organized general ledger, it's
time to start generating some orderly and well-organized reports.
This is where the Ledger tool comes in. With it, you can balance your
checkbook, see where your money is going, tell whether you've made a
profit this year, and even compute the present day value of your
retirement accounts. And all with the simplest of interfaces: the
command-line.
Something that stops many people from keeping a ledger at all is the
insanity of tracking cash expenses. They rarely generate a receipt,
and there are often a lot of small transactions, rather than a few
large ones, as with checks.
The most often used command will be the "balance" command:
The answer is: don't bother. Move your spending to a debit card, but
in general ignore cash. Once you withdraw it from the ATM, mark it as
already spent to an "Expenses:Cash" category:
<example>
/home/johnw $ export LEDGER=/home/johnw/doc/ledger.dat
/home/johnw $ ledger balance
2004/03/15 ATM
Expenses:Cash $100.00
Assets:Checking
</example>
Here I've set my Ledger environment variable to point to where my
ledger file is hiding. Thereafter, I needn't specify it again.
The balance command prints out the summarized balances of all my
top-level accounts, excluding sub-accounts. In order to see the
balances for a specific account, just specify a regular expression
after the balance command:
If at some point you make a large cash expense that you want to track,
just "move" the amount of the expense from "Expenses:Cash" into the
target account:
<example>
/home/johnw $ ledger balance expenses:food
2004/03/20 Somebody
Expenses:Food $65.00
Expenses:Cash
</example>
This will show all the money that's been spent on food, since the
beginning of the ledger. For food spending just this month
(September), use:
<example>
/home/johnw $ ledger -d sep balance expenses:food
</example>
Or maybe I want to see all of my assets, in which case the -s (show
sub-accounts) option comes in handy:
<example>
/home/johnw $ ledger balance -s
</example>
To exclude a particular account, use a regular expression with a
leading minus sign. The following will show all expenses, but without
food spending:
<example>
/home/johnw $ ledger balance expenses -food
</example>
If you want to show all accounts but for one account, remember to use
"--" to separate the exclusion pattern from the options list:
<example>
/home/johnw $ ledger balance -- -equity
</example>
This way, you can still track large cash expenses, while ignoring all
of the smaller ones.

As a Bahá'í, I need to compute Huqúqu'lláh whenever I acquire assets.
The exact details of this are a bit complex, so if you have further
interest, please consult the Web.
For any fellow Bahá'ís out there who want to track Huqúqu'lláh, the
Ledger tool makes this extraordinarily easy. Just too easy, in fact.
Here's all you have to do: If an expense is exempt from Huqúqu'lláh --
a "necessary" expense -- put an exclamation mark before the account
name:
Ledger tool makes this extremely easy. Just set up the following
automated transaction at the top of your ledger file:
<example>
2002.12.31 Rent
!Expenses:Rent $450.00
Assets:Checking $-450.00
; These entries will compute Huqúqu'lláh based on the
; contents of the ledger.
= ^Income:
= ^Expenses:Rent$
= ^Expenses:Furnishings
= ^Expenses:Business
= ^Expenses:Taxes
= ^Expenses:Insurance
(Liabilities:Huqúqu'lláh) 0.19
</example>
Even easier than that, simply put a list of regular expressions that
match the categories you consider exempt in a file called =.huquq=,
and the special marking will be done for you. Here is the file I use:
This automated transaction works by looking at each transaction
appearing afterward in the ledger file. If any match the account
regexps, occurring after the equal signs above, 19% of the value of
that transaction is applied to the "Liabilities:Huqúqu'lláh" account.
So if $1000 is earned through Income:Salary, which is seen as a debit
from Income, a debit of $190 is applied to "Liabilities:Huqúqu'lláh";
if $1000 is spent on Rent -- seen as a credit to the Expense account
-- a credit of $190 is applied to Huqúqu'lláh. The ultimate balance
of Huqúqu'lláh reflects how much must be paid to that account in order
to balance it to zero.
When you're ready to pay, just write a check directly to the account
"Liabilities:Huqúqu'lláh":
<example>
^Income:
^Retirement:
^Expenses:Rent
^Expenses:Taxes
</example>
When you're ready to pay Huqúqu'lláh, just write the check to the
account "Huququ'llah" (no accents, one apostrophe):
<example>
2003.01.20 * (101) Baha'i Huququ'llah Trust
Huququ'llah $1,000.00
Assets:Checking $-1,000.00
2003/01/01 (101) Baha'i Huqúqu'lláh Trust
Liabilities:Huqúqu'lláh $1,000.00
Assets:Checking
</example>
That's it. To see how much Huqúq is currently owed based on your
ledger data, type:

** Command summary
*** balance
The "balance" command reports the current balance of any account.
This command accepts a list of optional regexps, which will confine
the balance report to only matching accounts. By default, the
balances for all accounts will be printed. If an account contains
multiple types of commodities, each commodity's total is separately
reported.
*** register
The "register" command displays all the transactions occurring in a
single account, line by line. The account regexp must be specified as
the only argument to this command. If any regexps occur after the
required account name, the register will contain only those
transactions that match. Very useful for hunting down a particular
transaction.
The output from "register" is very close to what a typical checkbook,
or single account ledger, would look like. It also shows a running
balance. The final running balance of any register should always be
the same as the current balance of that account.
*** print
The "print" command prints out ledger entries just as they appear in
the original ledger. They will be properly formatted, and output in
the most economic form possible. The "print" command also takes a
list of optional regexps, which will cause only those transactions
which match in some way to be printed.
The "print" command is a handy way to clean up a ledger file whose
formatting has gotten out of hand.
*** equity
Equity transactions are used to establish the starting value of an
account. You might think of equity as the "ether" from which initial
balances appear.
The "equity" command makes it easy to archiving past years, and then
remove them without changing any current balances. For example, if
it's now 2004 and we want to archive all of 2003's transactions to
another file, write:
<example>
export LEDGER=ledger.dat
ledger -e 2004/1/1 print > ledger-2003.dat
ledger -e 2004/1/1 equity > /tmp/balances
ledger -b 2004/1/1 print > /tmp/current
cat /tmp/balances /tmp/current > ledger.dat
rm /tmp/balances /tmp/current
</example>
After these commands, **ledger-2003.dat** will contain all the
transactions up to year 2004, with **ledger.dat** containing only those
since 2004. However, the balances reported from **ledger.dat** will still
be the same.
Sometimes you will not want to carry forward certain balances, such as
those for Expense and Income. To do this, change the second command
above to:
<example>
ledger -e 2004/1/1 equity -^Income -^Expenses > /tmp/balances
</example>

** Option summary
-B ::
When printing accounts containing commodities, display the base
price for the commodity, rather than the quantity of that commodity
(the default) or its current price (if -P is used).
-b DATE ::
Only consider entries occuring on or after the given date.
-e DATE ::
Only consider entries occuring before the given date. The date is
not inclusive, so any entries occurring on that date will not be
used.
-c ::
Only consider entries occurring on or before the current date.
-C ::
Only consider entries whose cleared flag has been set. The default
is to consider both.
-d DATE ::
Only consider entries fitting the given date mask. DATE in this
case may be the name of a month, or a year, or a year and month,
such as "2004/05". It's a shorthand for having to specify -b and -e
together.
-E ::
Also show empty accounts in the balance totals report.
-f FILE[=ACCOUNT] ::
Read ledger entries from FILE. This takes precedence over the
environment variable LEDGER. If "=ACCOUNT" is appended to the
filename, then all of the entries are seen as if the transactions
accounts were prefixed by "ACCOUNT:". There may be multiple
occurrences of the -f option.
-F ::
Print full account names in all cases, such as "Assets:Checking"
instead of just "Checking". Only used current by the "balance"
command.
-h ::
Print out quick help on the various options and commands.
-i FILE ::
Read in the list of patterns to include/exclude from FILE.
Ordinarily, these are specified as arguments after the command.
-M ::
When used with the "register" command, causes only monthly subtotals
to appear. This can be useful for looking at spending patterns.
TODO: Accept an argument which specifies the period to use.
-G ::
Modifies the output generated by -M to be friendly to programs like
Gnuplot. It strips away the commodity label, and outputs only two
columns: the date and the amount.
-n ::
Do not show subtotals in the balance report, or split transactions
in the register report.
-N REGEXP ::
If an account matches REGEXP, only display it in the balance report
if its total is negative. Useful to avoid seeing credit in accounts
where one cannot spend that credit, and it will soon become negative
anyway (such as credit cards).
-p ARG ::
If a string, such as "COMM=$1.20", the commodity COMM will be
reported only in terms of its translated dollar value. This can be
used to perform arbitrary value substitutions. For example, to
report the value of your dollars in terms of the ounces of gold they
would buy, use: -p "$=0.00280112 AU" (or whatever the current
exchange rate is).
-P ::
Download current prices for all commodities by calling the script
"getquote". There is a "getquote" script included with ledger,
although any similar program could be used. It must take a single
argument, the name of the commodity, and must report the value as a
single amount, such as would appear in a ledger file. If the
commodity has no price, nothing should be output and the exit code
should be set to a non-zero value.
-R ::
Ignore all virtual transactions, and report only the real balance
for each account.
-s ::
If an account has children, show them in the balance report.
-S ::
Sort the ledger after reading it. This may affect "register" and
"print" output.
-U ::
Show only uncleared transactions. The default is to consider both.

The Ledger tool is fast and simple, but it gives you no special

someday soon to make editing Ledger's data files much easier.
The Ledger tool is fast and simple, but it offers no custom method for

Then again, why would anyone use a Gnome-centric, 35 megabyte behemoth
to edit their data, and a 65 kilobyte binary to query it...
* Using timeclock to record billable time
The timeclock tool makes it easy to track time events, like clocking
into and out of a particular job. These events accumulate in a
timelog file.
Each in/out event may have an optional description. If the "in"
description is a ledger account name, these in/out pairs may be viewed
as virtual transactions, adding time commodities (hours) to that
account.
For example, the command-line version of the timeclock tool (which is
written in Python) could be used to begin a timelog file like:
<example>
$ export TIMELOG=$HOME/.timelog
$ ti ClientOne category
$ sleep 10
$ to waited for ten seconds
</example>
The **.timelog** file now contains:
<example>
i 2004/10/06 15:21:00 ClientOne category
o 2004/10/06 15:21:10 waited for ten seconds
</example>
Ledger can parse this directly, as if it had seen the following ledger
entry:
<example>
2004/10/06 category
(ClientOne) 0.00277h
</example>
In other words, the timelog event pair is seen as adding 0.00277h (ten
seconds) worth of time to the ClientOne account. This would be
considered billable time, which later could be invoiced and credited
to accounts receivable:
<example>
2004/11/01 (INV#1) ClientOne, Inc.
Receivable:ClientOne $0.10
ClientOne -0.00277h @ $35.00
</example>
The above transaction converts the clocked time into an invoice for
the time spent, at an hourly rate of $35. Once the invoice is paid,
the money is deposited from the receivable account into a checking
account:
<example>
2004/12/01 ClientOne, Inc.
Assets:Checking $0.10
Receivable:ClientOne
</example>
And now the time spent has been turned into hard cash in the checking
account.
The advantage to using timeclock and invoicing to bill time is that
you will always know, by looking at the balance report, exactly how
much unbilled and unpaid time you've spent working for any particular
client.
I like to =!include= my timelog at the top of my company's accounting
ledger, with the attached prefix "Billable":
<example>
; -*-ledger-*-
; This is the ledger file for my company. But first, include the
; timelog data, entering all of the time events within the umbrella
; account "Billable".
!include /home/johnw/.timelog Billable
; Here follows this fiscal year's transactions for the company.
2004/11/01 (INV#1) ClientOne, Inc.
Receivable:ClientOne $0.10
Billable:ClientOne -0.00277h @ $35.00
2004/12/01 ClientOne, Inc.
Assets:Checking $0.10
Receivable:ClientOne
</example>
Footnotes:
[1] In some special cases, it will automatically balance the entry
for you.

Welcome to ledger, a command-line accounting program that uses a
text-based ledger file, yet provides full double-entry accounting, use
of commodities, unlimited accounts, etc.
Ledger is written in ANSI C++, and should compile on any platform. It
only depends on the GNU multiprecision integer library (gmp, or
libgmp), and the Perl regular expression library (pcre, or libpcre).
Also, this project was developed using GNU make and gcc 3.3.
To build and install, once you have these libraries on your system,
enter these commands:
@example
make
cp ledger /usr/local/bin
@end example

@chapter Introduction
Ledger is an accounting tool with the moxie to exist. It provides not
one bell or whistle for the money, and returns the user to the days
before user interfaces were even a twinkle in their father's CRT.
What it does do is provide a double-entry accounting ledger with all
of the flexibility and muscle of its modern day cousins---without any
of the fat. Think of it as the bran muffin of accounting tools.
To begin with, you need to start keeping a ledger. This is the basis
of all accounting, and if you don't know how to do it, now is the time
to learn. The little booklet that comes with your checkbook is a
ledger, so we'll describe double-entry accounting in terms of that.
A checkbook ledger records debits (subtractions, or withdrawals) and
credits (additions, or deposits) with reference to a single account:
your checking account. Where the money comes from, and where it goes
to, are simply described in the memo field where you write the person
or the company's name. The ultimate aim of keeping a checkbook ledger
is so you know how much money is available to spend at all times.
That is really the aim of all ledgers.
What computers add is the ability to walk through all of those
transactions and tell you things about your spending habits; let you
devise budgets to get control over your spending; squirrel away money
into virtual savings account without having to physically move the
money around; etc. As you keep your checkbook ledger, you are
recording a lot of information about your life and your habits, and
sometimes that information can tell you things you aren't even aware
of. That is the aim of all good accounting tools.
The next step up from a checkbook ledger is a ledger that covers all
of your accounts, not just your checking account. In this ledger, you
write not only who the money goes to---in the case of a debit---but
where the money is coming from. In the checkbook ledger, its assumed
that all of the money is coming from your checking account. But in a
general ledger, you have to write two-lines: The source and target.
There must always be a debit from some account for any credit made to
anyone else. This is what is meant by ``double-entry'' accounting.
For example, let's say you have a checking account and a brokerage
account, and that you can write checks from both of them. Rather than
keeping two checkbooks, you decide to use one ledger for both. Once
you get the hang of this, you'll be ready to use one ledger for all of
your accounting needs, which gets you to the point of this
introduction.
So in your general ledger, you need to pay Pacific Bell Telephone for
your monthly phone bill. The cost is $23.00. In a checkbook ledger,
you would write out a line that credits your account with Pacific Bell
by $23 as follows:
@example
9/29 100 Pacific Bell $23.00 $77.00
@end example
Very simple: You've written check #100 for $23 to Pacific Bell, which
leaves your balance in checking at $77.
But in a general ledger, you need to say where the money is coming
from. A general ledger entry would look like this:
@example
9/29 100 Pacific Bell $23.00 $223.00
Checking $-23.00 $77.00
@end example
What does all of this mean? The first line shows a credit (or
payment) to Pacific Bell to the tune of $23.00. Then, because there
is no one ``balance'' in a general ledger, we've written in the total
balance of your payments to the account ``Pacific Bell''. This was done
by looking at the last entry for ``Pacific Bell'' in the general ledger,
adding $23.00 to that amount, and writing in the total in the balance
column.
Secondly, the money is coming from your ``Checking'' account, which
means a debit (or withdrawal) of $23.00, which will leave the ending
balance in your ``Checking'' account at $77.00.
The transaction itself must balance to $0: $23 goes to Pacific Bell,
$23 comes from Checking: there is nothing left over to be accounted
for. The money has in fact moved from one account to another. This
is basis of double-entry accounting: That money never pops out of
existence, it is always described as a transaction between accounts---
as a flow from one place to another.
Keeping a general ledger is the same as keeping two separate ledgers:
One for Pacific Bell and one for Checking. In that case, each time
you write a credit into one, you write a corresponding debit into the
other. This makes it much easier to write in the running balance,
since you don't have to go looking back for the last time an account
was referenced, but it also means having a lot of ledger books if you
deal with multiple accounts.
Enter the beauty of a computerized accounting tool. The purpose of
Ledger is to make general ledger accounting simple by keeping track of
the balances for you. Your only job is to enter credit/debit pairs
and make sure they balance. If a transaction does not balance, Ledger
will display an error and ignore the transaction.@footnote{In some special cases, it will automatically balance the entry
for you.}
Your usage of Ledger will have two parts: Keeping the ledger, and
using the Ledger tool to provide you with information summaries
derived from your ledger's entries.
@node Keeping a ledger, Using the Ledger Tool, Introduction, Top
@chapter Keeping a ledger
The most important part of accounting is keeping a good ledger. If
you have a good ledger, tools can be written to work whatever
mathematically tricks you need to better understand your spending
patterns. Without a good ledger, no tool, however smart, can help
you.
The Ledger program aims at making ledger entry as simple as possible.
Since it is a command-line tool, it does not provide a user interface
for keeping a ledger. If you like, you may use Gnucash to maintain
your ledger, in which case the Ledger program will read Gnucash's data
files directly. In that case, read the Gnucash manual now, and skip
to the next chapter.
If you are not using Gnucash, but a text editor to maintain your
ledger, read on. Ledger has been designed to make data entry as
simple as possible, by keeping the ledger format easy, and also by
automagically determining as much information as possible based on the
nature of your entries.
For example, you do not need to tell Ledger about the accounts you
use. Any time Ledger sees a debit or a credit to an account it knows
nothing about, it will create it. If you use a commodity that is new
to Ledger, it will create that commodity, and determine its display
characteristics (placement of the symbol before or after the amount,
display precision, etc) based on how you used the commodity in the
transaction.
Here is the Pacific Bell example from above, given as a Ledger
transaction:
@example
9/29 (100) Pacific Bell
Expenses:Utilities:Telephone $23.00
Assets:Checking $-23.00
@end example
As you can see, it is very similar to what would be written on paper,
minus the computed balance totals, and adding in account names that
work better with Ledger's scheme of things. In fact, since Ledger is
smart about many things, you don't need to specify the balanced
amount, if it is the same as the first line:
@example
9/29 (100) Pacific Bell
Expenses:Utilities:Telephone $23.00
Assets:Checking
@end example
For this entry, Ledger will figure out that $-23.00 must come from
``Assets:Checking'' in order to balance the entry.

@node Credits and Debits, Commodities and Currencies, Keeping a ledger, Keeping a ledger
@section Credits and Debits
Credit and debit are simple enough terms in themselves, but the usages
of the modern world have made them very hard to puzzle out.
Basically, a credit means you add something to an account, and a debit
means you take away. A debit card is correctly name: From your point
of view, it debits your checking account every time you use it.
The credit card is strangely named, because you have to look at it
from the merchant's point of view: Every time you use it, it credit's
@emph{his} account right away. This was a giant leap from the days of cash
and checks, when the only other way to supply immediate credit was by
a wire transfer. But a credit card does not credit you anything at
all. In fact, from your point of view, it should be called a
liability card, since it increases your liability to the issuing bank
every time you use it.
In Ledger, credits and debits are given as they are, which means that
sometimes you will see a minus sign where you don't expect one. For
example, when you get paid, in order to credit your bank account, you
need to debit an income account:
@example
9/29 My Employer
Assets:Checking $500.00
Income:Salary $-500.00
@end example
But wait, you say, why is the Income a negative figure? And when you
look at the balance totals for your ledger, you will certainly be
surprised to see Expenses as a positive figure, and Income as a
negative figure. Isn't that the opposite of how it should look?
It may take getting used to, but to properly use a general ledger you
will need to think in terms of correct debits and credits. Rather
than Ledger ``fixing'' the minus signs, let's understand why they are
there.
When you earn money, the money has to come from somewhere. Let's call
that somewhere ``society''. In order for society to give you an income,
you must take money away from society (debit) in order to put it into
your bank (credit). When you then spend that money, it leaves your
bank account (debit) and goes back to society (credit). This is why
Income will appear negative---it reflects the money you have drawn
from society---and why Expenses will be positive---it is the amount
you've given back. These credits and debits will always cancel each
other out in the end, because you don't have the ability to create new
money: It must always come from somewhere, and in the end must always
leave. This is the beginning of economy, after which the explanation
gets terribly difficult.
Based on that explanation, here's another way to look at your balance
report: Every negative figure means that that account or person or
place has less money now than when you started your ledger; and every
positive figure means that that account or person or place has more
money now that when you started your ledger. Make sense?
Also, credit cards will have a negative value, because you are
spending @emph{from} them (debit) in order pay someone else (credit). They
are called credit cards because you are able to instantly credit that
other person, by simply waving a card.
@node Commodities and Currencies, Accounts and Inventories, Credits and Debits, Keeping a ledger
@section Commodities and Currencies
Ledger makes no assumptions about the commodities you use; it only
requires that you specify a commodity. The commodity may be any
non-numeric string that does not contain a period, comma, forward
slash or at-sign. It may appear before or after the amount, although
it is assumed that symbols appearing before the amount refer to
currencies, while non-joined symbols appearing after the amount refer
to commodities. Here are some valid currency and commodity
specifiers:
@example
$20.00 ; currency: twenty US dollars
USD 20 ; currency: the same
40 AAPL ; commodity: 40 shares of Apple stock
MD 60 ; currency: 60 Deutsch Mark
£50 ; currency: 50 British pounds
50e ; currency: 50 Euros (use symbol)
@end example
Ledger will examine the first use of any commodity to determine how
that commodity should be printed on reports. It pays attention to
whether the name of commodity was separated from the amount, whether
it came before or after, the precision used in specifying the amount,
whether thousand marks were used, etc. This is done so that printing
the commodity looks the same as the way you use it.
An account may contain multiple commodities, in which case it will
have separate totals for each. For example, if your brokerage account
contains both cash, gold, and several stock quantities, the balance
might look like:
@example
$200.00
100.00 AU
AAPL 40
BORL 100
FEQTX 50 Assets:Brokerage
@end example
This balance report shows how much of each commodity is in your
brokerage account.
Sometimes, you will want to know the current street value of your
balance, and not the commodity totals. For this to happen, you must
specify what the current price is for each commodity. The price can
be in any commodity, in which case the balance will be computed in
terms of that commodity. The usual way to specify prices is with a
file of price settings, which might look like this:
@example
AU=$357.00
AAPL=$37
BORL=$19
FEQTX=$32
@end example
Specify the prices file using the @samp{-p} option:
@example
/home/johnw $ ledger -p prices.db balance brokerage
@end example
Now the balance for your brokerage account will be given in US
dollars, since the prices database has specified conversion factors
from each commodity into dollars:
@example
$40880.00 Assets:Brokerage
@end example
You can convert from any commodity to any other commodity. Let's say
you had $5000 in your checking account, and for whatever reason you
wanted to know many ounces of gold that would buy. If gold is
currently $357 per ounce, then each dollar is worth 1/357 AU:
@example
/home/johnw $ ledger -p "$=0.00280112 AU" balance checking
@end example
@example
14.01 AU Assets:Checking
@end example
$5000 would buy 14 ounces of gold, which becomes the new display
commodity since a conversion factor was provided.
Commodities conversions can also be chained, up to a depth of 10.
Here is a sample prices database that uses chaining:
@example
AAPL=$15
$=0.00280112 AU
AU=300 Euro
Euro=MD 0.75
@end example
This is a roundabout way of reporting AAPL shares in their Deutsch
Mark equivalent.
@node Accounts and Inventories, Understanding Equity, Commodities and Currencies, Keeping a ledger
@section Accounts and Inventories
Since Ledger's accounts and commodity system is so flexible, you can
have accounts that don't really exist, and use commodities that no one
else recognizes. For example, let's say you are buying and selling
various items in EverQuest, and want to keep track of them using a
ledger. Just add items of whatever quantity you wish into your
EverQuest account:
@example
9/29 Get some stuff at the Inn
Places:Black's Tavern -3 Apples
Places:Black's Tavern -5 Steaks
EverQuest:Inventory
@end example
Now your EverQuest:Inventory has 3 apples and 5 steaks in it. The
amounts are negative, because you are taking @emph{from} Black's Tavern in
order to credit your Inventory account. Note that you don't have to
use ``Places:Black's Tavern'' as the source account. You could use
``EverQuest:System'' to represent the fact that you acquired them
online. The only purpose for choosing one kind of source account over
another is for generate more informative reports later on. The more
you know, the better analysis you can perform.
If you later sell some of these items to another player, the entry
would look like:
@example
10/2 Strum Brightblade
EverQuest:Inventory -2 Steaks
EverQuest:Inventory 15 Gold
@end example
Now you've turned 2 steaks into 15 gold, courtesy of your customer,
Strum Brightblade.
@node Understanding Equity, , Accounts and Inventories, Keeping a ledger
@section Understanding Equity
The most confusing entry in any ledger will be your equity account---
because starting balances can't come out of nowhere.
When you first start your ledger, you will likely already have money
in some of your accounts. Let's say there's $100 in your checking
account; then add an entry to your ledger to reflect this amount.
Where will money come from? The answer: your equity.
@example
10/2 Opening Balance
Assets:Checking $100.00
Equity:Opening Balances $-100.00
@end example
But what is equity? You may have heard of equity when people talked
about house mortgages, as ``the part of the house that you own''.
Basically, equity is like the value of something. If you own a car
worth $5000, then you have $5000 in equity in that car. In order to
turn that car (a commodity) into a cash flow, or a credit to your bank
account, you will have to debit the equity by selling it.
When you start a ledger, you are probably already worth something.
Your net worth is your current equity. By transferring the money in
the ledger from your equity to your bank accounts, you are crediting
the ledger account based on your prior equity value. That is why,
when you look at the balance report, you will see a large negative
number for Equity that never changes: Because that is what you were
worth (what you debited from yourself in order to start the ledger)
before the money started moving around. If the total positive value
of your assets is greater than the absolute value of your starting
equity, it means you are making money.
Clear as mud? Keep thinking about it. Until you figure it out, put
``-- -Equity'' at the end of your balance command, to remove the
confusing figure from the totals.
@node Using the Ledger Tool, An easy way to add new entries, Keeping a ledger, Top
@chapter Using the Ledger Tool
Now that you have an orderly and well-organized general ledger, it's
time to start generating some orderly and well-organized reports.
This is where the Ledger tool comes in. With it, you can balance your
checkbook, see where your money is going, tell whether you've made a
profit this year, and even compute the present day value of your
retirement accounts. And all with the simplest of interfaces: the
command-line.
The most often used command will be the ``balance'' command:
@example
/home/johnw $ export LEDGER=/home/johnw/doc/ledger.dat
/home/johnw $ ledger balance
@end example
Here I've set my Ledger environment variable to point to where my
ledger file is hiding. Thereafter, I needn't specify it again.
The balance command prints out the summarized balances of all my
top-level accounts, excluding sub-accounts. In order to see the
balances for a specific account, just specify a regular expression
after the balance command:
@example
/home/johnw $ ledger balance expenses:food
@end example
This will show all the money that's been spent on food, since the
beginning of the ledger. For food spending just this month
(September), use:
@example
/home/johnw $ ledger -d sep balance expenses:food
@end example
Or maybe I want to see all of my assets, in which case the -s (show
sub-accounts) option comes in handy:
@example
/home/johnw $ ledger balance -s
@end example
To exclude a particular account, use a regular expression with a
leading minus sign. The following will show all expenses, but without
food spending:
@example
/home/johnw $ ledger balance expenses -food
@end example
If you want to show all accounts but for one account, remember to use
``--'' to separate the exclusion pattern from the options list:
@example
/home/johnw $ ledger balance -- -equity
@end example

@node Virtual transactions, Automated transactions, Using the Ledger Tool, Using the Ledger Tool
@section Virtual transactions
A virtual transaction is when you, in your mind, see money as moving
to a certain place, when in reality that money has not moved at all.
There are several scenarios in which this type of tracking comes in
handy, and each of them will be discussed in detail.
To enter a virtual transaction, surround the account name in
parentheses. This form of usage does not need to balance. However,
if you want to ensure the virtual transaction balances with other
virtual transactions in the same entry, use square brackets. For
example:
@example
10/2 Paycheck
Assets:Checking $1000.00
Income:Salary $-1000.00
(Debt:Alimony) $200.00
@end example
In this example, after receiving a paycheck an alimony debt is
increased---even though no money has moved around yet.
@example
10/2 Paycheck
Assets:Checking $1000.00
Income:Salary $-1000.00
[Savings:Trip] $200.00
[Assets:Checking] $-200.00
@end example
In this example, $200 has been deducted from checking toward savings
for a trip. It will appear as though the money has been moved from
the account into ``Savings:Trip'', although no money has actually moved
anywhere.
When balances are displayed, virtual transactions will be factored in.
To view balances without any virtual balances factored in, using the
``-R'' flag, for ``Reality''.

As a Bahá'í, I need to compute Huqúqu'lláh on some of my assets. The
exact details of this matter are rather complex, so if you have any
interest, I encourage you to do research on the Web.
For any fellow Bahá'ís out there who want to track Huqúqu'lláh, the
Ledger tool makes this extraordinarily easy. Just too easy, in fact.
Here's all you have to do: If an expense is exempt from Huqúqu'lláh---
a ``necessary'' expense---put an exclamation mark before the account
name:
@example
2002.12.31 Rent
!Expenses:Rent $450.00
Assets:Checking $-450.00
@end example
Even easier than that, simply put a list of regular expressions that
match the categories you consider exempt in a file called @samp{.huquq},
and the special marking will be done for you. Here is the file I use:
@example
^Income:
^Retirement:
^Expenses:Rent
^Expenses:Taxes
@end example
When you're ready to pay Huqúqu'lláh, just write the check to the
account ``Huququ'llah'' (no accents, one apostrophe):
@example
2003.01.20 * (101) Baha'i Huququ'llah Trust
Huququ'llah $1,000.00
Assets:Checking $-1,000.00

That's it. To see how much Huqúq is currently owed based on your
ledger data, type:
@example

@node An easy way to add new entries, Using Emacs to Keep Your Ledger, Using the Ledger Tool, Top
@chapter An easy way to add new entries
The three most laborious tasks of keeping a ledger are: adding new
entries, reconciling accounts, and generating reports. To address the
first of these, there is a sub-command to ledger called ``entry''. It
works on the principle that 80% of all transactions are variants of
earlier transactions. Here's how it works:
Let's say you have an old transaction of the following form:
@example
2004/03/15 * Viva Italiano
Expenses:Food $12.45
Expenses:Tips $2.55
Liabilities:MasterCard $-15.00
@end example
Now it's 2004/4/9, and you've just eating at Viva Italiano again. The
exact amounts are different, but the overall form is the same. With
the ``entry'' command you can type:
@example
ledger entry 2004/4/9 viva food 11.00 tips 2.50
@end example
This will produce the following output:
@example
2004/04/09 Viva Italiano
Expenses:Food $11.00
Expenses:Tips $2.50
Liabilities:MasterCard $-13.50
@end example
This works by finding a transaction that matches the regexp ``viva'',
and then assuming that any accounts or amounts you specify will be the
same as that earlier transaction. If Ledger does not succeed in
generating a new entry for you, it will print an error and set the
exit code to 1.
There is a shell script in the distribution called ``entry'', which
simplifies the task of adding a new entry to your ledger, and then
launches @samp{vi} to let you confirm that the entry looks appropriate.
@node Using Emacs to Keep Your Ledger, Using GnuCash to Keep Your Ledger, An easy way to add new entries, Top
@chapter Using Emacs to Keep Your Ledger
In the Ledger tarball is an Emacs module, @samp{ledger.el}. This module
makes the process of keeping a text ledger much easier for Emacs
users. I recommend putting this at the top of your ledger file:
@example
; -*-ledger-*-
@end example
And this in your @samp{.emacs} file, after copying @samp{ledger.el} to your
site-lisp directory:
@example
(load "ledger")
@end example
Now when you edit your ledger file, it will be in @samp{ledger-mode}.
@samp{ledger-mode} adds the following commands:
@table @strong
@item C-c C-a
For quickly adding new entries based on the form of older ones
(see previous section).
@item C-c C-c
Toggles the ``cleared'' flag of the transaction under point.
@item C-c C-r
Reconciles an account by displaying the transactions in another
buffer, where simply hitting the spacebar will toggle the cleared
flag of the transaction in the ledger. It also displays the current
cleared balance for the account in the modeline.

@node Using GnuCash to Keep Your Ledger, , Using Emacs to Keep Your Ledger, Top
@chapter Using GnuCash to Keep Your Ledger
The Ledger tool is fast and simple, but it gives you no special
method of actually editing the ledger. It assumes you know how to use
a text editor, and like doing so. Perhaps an Emacs mode will appear
someday soon to make editing Ledger's data files much easier.
Until then, you are free to use GnuCash to maintain your ledger, and
the Ledger program for querying and reporting on the contents
of that ledger. It takes a little longer to parse the XML data format
that GnuCash uses, but the end result is identical.
Then again, why would anyone use a Gnome-centric, 35 megabyte behemoth
to edit their data, and a 65 kilobyte binary to query it...
