@top Overview

Ledger is a command line accounting tool that provides double-entry
accounting based on a text journal.  It provides no bells or whistles,
and returns the user to the days before user interfaces were even
a 1twinkling in their father's CRT.

Ledger-mode assists you in maintaining input files for Ledger, running
reports and much more...

@section Quick Installation
@cindex installation

The Emacs lisp source for Ledger-mode is included with the source
distribution of Ledger.  It is entirely included in the @file{lisp}
subdirectory. To use Ledger-mode, include the following in your Emacs
initialization file (@file{~/.emacs}, @file{~/.emacs.d/init.el}, or
@file{~/.Aquamacs/Preferences.el}).

@lisp
(add-to-list 'load-path
             (expand-file-name "/path/to/ledger/source/lisp/"))
(load "ledger-mode")
(add-to-list 'auto-mode-alist '("\\.ledger$" . ledger-mode))
@end lisp

This sets up Emacs to automatically recognize files that end with
@file{.ledger} and start Ledger-mode.  Nothing else should be required
as long as the ledger command line utility is properly installed.

@subsection Quick Add
@kindex C-c TAB
@kindex C-c C-a

As simple as the Ledger transaction format is, it can still be daunting
to add many transactions manually.  Ledger provides two way to add
transactions with minimal typing. Both are based on the idea that most
transactions are repetitions of earlier transactions.

In the @file{demo.ledger} buffer enter a date using the correct
format. Then type the first few characters of another payee in the
@file{demo.ledger} buffer.  Type @kbd{C-c TAB}.  Ledger-mode will
search for a Payee that has the same beginning and copy the rest of the
transaction to you new entry.

Additionally you can use the ledger @command{xact} command, by either
typing @kbd{C-c C-a} or using @samp{Add Transaction} menu entry. Then
typing a close match to the payee. Ledger-mode will call @command{ledger
xact} with the data you enter and place the transaction in the proper
chronological place in the ledger.

@node Reconciliation, Reports, Quick Add, Quick Demo
@subsection Reconciliation
@kindex C-c C-r
@kindex SPC
@kindex C-c C-c
@kindex q

The biggest task of maintaining a ledger is ensuring that it matches the
outside world.  This process is called reconciliation (@pxref{Basics of
Reconciliation}) and can be quite onerous.  Ledger-mode attempts to make
it as painless as possible.

In the @file{demo.ledger} buffer type @kbd{C-c C-r}.  Emacs will prompt
for an account to reconcile in the Minibuffer.  Enter @samp{Checking}.
Emacs will then prompt for a target value.  The target value is the
amount you want the cleared transactions in the buffer to total.
Normally this would be the ending value from your bank statement, or the
latest value in your on-line transaction summary.  Enter @samp{1710}.
Note that Ledger-mode assumes your are using @samp{$} (USD) as your
default commodity, this can be easily changed in the customization
variables. @xref{Ledger-mode Customization}.

You now see a list of uncleared transactions in a buffer below the
@file{demo.ledger} buffer.  Touching the @kbd{SPC} bar will mark
a transaction as pending and display the current cleared (and pending)
balance, along with the difference remaining to meet your target. Clear
the first three transactions, and you will see the difference to target
reach @samp{$0}.  End the reconciliation by typing @kbd{C-c C-c}.  This
saves the @file{demo.ledger} buffer and marks the transactions and
finally cleared.  Type @kbd{q} to close out the reconciliation buffer.

@node Reports, Narrowing, Reconciliation, Quick Demo
@subsection Reports
@kindex C-c C-o C-r
@kindex C-c C-c

The real power of Ledger is in it reporting capabilities.  Reports can
be run and displayed in a separate Emacs buffer.  In the
@file{demo.ledger} buffer, type @kbd{C-c C-o C-r}.  In the Minibuffer
Emacs will prompt for a report name.  There are a few built-in reports,
and you can add any report you need @xref{Adding and Editing Reports}.

In the Minibuffer type @samp{account}.  When prompted for an account
type @samp{checking}.  In another buffer you will see a Ledger register
report. You can move around the buffer, with the point on a transaction,
type @kbd{C-c C-c}.  Ledger-mode will take you directly to that
transaction in the @file{demo.ledger} buffer.

Another built-in report is the balance report.  In the
@file{demo.ledger} buffer, type @kbd{C-c C-o C-r}.  When prompted for
a report to run, type @samp{bal}, and a balance report of all accounts
will be shown.

@node Narrowing,  , Reports, Quick Demo
@subsection Narrowing
@kindex C-c C-f

A ledger file can get very large.  It can be helpful to collapse the
buffer to display only the transactions you are interested in.
Ledger-mode copies the @command{occur} mode functionality.  Typing
@kbd{C-c C-f} and entering any regex in the Minibuffer will show only
transactions that match the regex.  The regex can be on any field, or
amount.

Beyond the two ways of quickly adding transactions (@pxref{Quick Add})
Ledger-mode assists you by providing robust @kbd{TAB} completion for
payees and accounts.  Ledger-mode will scan the existing buffer for
payees and accounts. Included files are not currently included in the
completion scan. Repeatedly hitting @kbd{TAB} will cycle through the
possible completions.

Ledger-mode can also help you keep your amounts in alignment.  Setting
@option{ledger-post-auto-adjust-amounts} to true tells Ledger-mode to
automatically place any amounts such that their last digit is aligned to
the column specified by @option{ledger-post-amount-alignment-column},
which defaults to @samp{52}. @xref{Ledger Post Customization Group}.

the balance of the account will be displayed in the Minibuffer.

@node Copying Transactions, Editing Amounts, Adding Transactions, The Ledger Buffer
@section Copying Transactions
@kindex C-c C-k
@cindex transaction, copying

An easy way to copy a transaction is to type @kbd{C-c C-k} or menu entry
@samp{Copy Trans at Point}. You will be prompted the new date for the
copied transaction, and after having confirmed with @kbd{RET}, new
transaction will be inserted at @emph{date} position in buffer.

@section Editing Amounts

@cindex Calc
@cindex GNU Emacs Calculator
@cindex transaction, editing amounts

GNU Emacs Calculator, aka @samp{Calc}, is a very powerful Reverse Polish
Notation calculator built into all recent version of Emacs.  Ledger-mode
makes it easy to calculate values for amount by integrating
@command{Calc}. With the point anywhere in the same line as a posting,
typing @kbd{C-c C-b} will bring up the @file{Calc} buffer, and push the
current amount for the posting onto the top of the @command{Calc} stack.
Perform any calculations you need to arrive at the final value, then
type @kbd{y} to yank the value at the top of stack back into the ledger
buffer.  Note: @command{Calc} does not directly support commas as
decimal separators.  Ledger-mode will translate values from
decimal-comma format to decimal-period format for use in @command{Calc},
but it cannot intercept the value being yanked form the @command{Calc}
stack, so decimal-comma users will have to manually replace the period
with a comma.

@node Marking Transactions, Deleting Transactions, Editing Amounts, The Ledger Buffer
@section Marking Transactions
@cindex transaction, marking
@cindex uncleared
@cindex pending
@cindex cleared

Ledger considers transaction or posting to be in one of three states:
uncleared, cleared, and pending.  For calculation Ledger ignores these
states unless specifically instructed to use them.  Ledger-mode assigns
some additional meaning to the states:

@itemize

@item Uncleared.
No state.  This is equivalent to sticking a check in the mail.  It has
been obligated, but not been cashed by the recipient.  It could also
apply to credit/debit card transactions that have not been cleared into
your account balance.  You bank may call these transactions ``pending'',
but Ledger-mode uses a slightly different meaning.

@item Pending.
Ledger-mode's reconciliation function see pending transactions as an
intermediate step in reconciling an account.  When doing
a reconciliation (@pxref{Reconciliation}), marking a transaction as
pending means that you have seen the transaction finally recorded by the
recipient, but you have not completely reconciled the account.

@item Cleared.
The transaction has been completely recognized by all parties to the
transaction.

@end itemize

@kindex C-c C-e
@kindex C-c C-c

Clearing complete transactions is done by typing @kbd{C-c C-e} with
point in a transaction.  This places an asterisk @samp{*} after the
date.  Clearing individual postings is done by typing @kbd{C-c C-c}
while in a posting. This places an asterisk prior to the posting.

@node Deleting Transactions, Sorting Transactions, Marking Transactions, The Ledger Buffer
@section Deleting Transactions
@kindex C-c C-d
@cindex transaction, deleting

Along with normal buffer editing methods to delete text, Ledger-mode
provides an easy way to delete the transaction under point: @kbd{C-c
C-d}.  The advantage to using this method is that the complete
transaction operation is in the undo buffer.

@node Sorting Transactions, Narrowing Transactions, Deleting Transactions, The Ledger Buffer
@section Sorting Transactions
@kindex C-c C-s
@cindex transaction, sorting

As you operating on the Ledger files, they may become disorganized.  For
the most part, Ledger doesn't care, but our human brains prefer a bit of
order.  Sorting the transactions in a buffer into chronological order
can help bring order to chaos.  Either using @samp{Sort Region} menu
entry or typing @kbd{C-c C-s} will sort all of the transactions in
a region by date.  Ledger-mode isn't particularly smart about handling
dates and it simply sorts the transactions using the string at the
beginning of the transaction.  So, you should use the preferred ISO 8601
standard date format @samp{YYYY/MM/DD} which easily sorts.

Note, there is a menu entry @samp{Sort Buffer} to sort the entire
buffer.  Special transactions like automated transaction, will be moved
in the sorting process and may not function correctly afterwards.  For
this reason there is no key sequence.

You can limit the allowed sort region by using embedded Ledger-mode
markup within your ledger.  For example:

@example
<<< information to not sort >>>

; Ledger-mode: Start sort

<<< transactions to sort >>>

; Ledger-mode: End sort

<<< information to not sort >>>
@end example

You can use menu entries @samp{Mark Sort Beginning} to insert start and
@samp{Mark Sort End} to insert end markers.  These functions will
automatically delete old markers and put new new marker at point.

@node Narrowing Transactions,  , Sorting Transactions, The Ledger Buffer
@section Narrowing Transactions
@kindex C-c C-f
@cindex transaction, narrowing
@cindex transaction, display filtering

Often you will want to run Ledger register reports just to look at
a specific set of transactions.  If you don't need the running total
calculation handled by Ledger, Ledger-mode provides a rapid way of
narrowing what is displayed in the buffer in a way that is simpler than
the Ledger register command.

Based on the Emacs Occur mode by Alexey Veretennikov, Ledger-occur hides
all transactions that do @emph{not} meet a specific regular expression.
The regular expression can match on any part of the transaction.  If you
want to find all transactions whose amount ends in @samp{.37}, you can
do that (I don't know why, but hey, whatever ever floats you aerostat).

Using @kbd{C-c C-f} or the @samp{Narrow to Regex} menu entry, enter
a regular expression in the Minibuffer.  Ledger-mode will hide all other
transactions.  For details of the regular expression syntax, see
@ref{(emacs)Regexps, Syntax of Regular Expressions} or
@ref{(elisp)Regular Expressions, Regular Expressions}.  A few examples
using the @file{demo.ledger} are given here:

@table @samp

@item Groceries
Show only transactions that have a posting to the @samp{Groceries}
account.

@item ^2011/01
Show only transactions occurring in January of 2011.

@item ^2011/.*/25
Show only transactions occurring on the 25th of the month in 2011.

@item auto
Show only transactions with payees or accounts or comments containing.
@samp{auto}

@item harley$
Show only transactions with any line ending with @samp{harley}.

@end table

To show back all transactions simply invoke @samp{Narrow to Regex} or
@kbd{C-c C-f} again.

@cindex reconciliation, basics

Even in this relatively modern era, financial transactions do not happen
instantaneously, unless you are paying cash.  When you swipe your debit
card the money may take several days to actually come out of your
account, or a check may take several days to @emph{clear}.  That is the
root of the difference between @emph{obligating} funds and
@emph{expending} funds.  Obligation says you have agreed to pay it, the
expenditure doesn't happen until the money actually leaves your
account. Or in the case of receiving payment, you have an account
receivable until the money has actually made it to you.

After an account has been reconciled you have verified that all the
transactions in that account have been correctly recorded and all
parties agree.

@node Starting a Reconciliation, Mark Transactions Pending, Basics of Reconciliation, The Reconcile Buffer
@section Starting a Reconciliation
@findex ledger-reconcile-default-commodity
@kindex C-c C-r
@cindex reconciliation, starting

To start reconciling an account you must have a target, both the
transactions that you know about and the transactions the bank knows
about.  You can get this from a monthly statement, or from checking your
on-line transaction history.  It also helps immensely to know the final
cleared balance you are aiming for.

Use menu @samp{Reconcile Account} or @kbd{C-c C-r} and enter the account
you wish to reconcile in the Minibuffer.  Ledger-mode is not particular
about what you enter for the account.  You can leave it blank and
@file{*Reconcile*} buffer will show you @emph{all} uncleared
transactions.  After you enter the account enter the target amount.
Ledger expects you to enter an amount with a commodity.  It assumes
initially that you are using @samp{$} (USD) as your default commodity.
If you are working in a different currency you can change the default in
variable @option{ledger-reconcile-default-commodity} to whatever you
need.  If you work in multiple commodities simply enter the commoditized
amount (for example @samp{340 VSDX}, for 340 shares of VSDX).

Ledger-mode reconcile cannot currently reconcile accounts that have
multiple commodities, such as brokerage accounts. You may use
reconciliation mode to clear transactions, but balance calculations will
not display the complete list of commodities.

@node Mark Transactions Pending, Edit Transactions During Reconciliation, Starting a Reconciliation, The Reconcile Buffer
@section Mark Transactions Pending
@kindex SPC
@cindex reconciliation, transaction marking

The @file{*Reconcile*} buffer will show all the uncleared transactions
that meet the criteria set in the regex.  By default uncleared
transactions are shown in red.  When you have verified that
a transaction has been correctly and completely recorded by the opposing
party, mark the transaction as pending using the @kbd{SPC} bar.
Continue this process until you agree with the opposing party and the
difference from your target is zero.

If you type a report name that Ledger-mode doesn't recognize it will
prompt you for a ledger command line to run.  That command is
automatically saved with the name given and you can re-run it at any
time.

There are two ways to edit the command line for a report. The first is
to provide a prefix argument to the run-report command.  For example,
type @kbd{M-1 C-c C-o C-r}. This will prompt you for the report name,
then present the report command line to be edited.  When you hit
@kbd{RET}, the report will be run, but it will not be permanently saved.
If you want to save it, type @kbd{S} in the @file{*Ledger Report*}
buffer you will have the option to give it a new name, or overwrite the
old report.

Deleting reports is accomplished by typing @kbd{C-c C-o C-e} or using
@samp{Edit Reports} menu in the ledger buffer, or typing @kbd{e} in the
@file{*Ledger Report*} buffer.  This takes you to the Emacs
customization window for the Ledger Reports variables.  Use the widgets
to delete the report you want removed.

@node Expansion Formats, Make Report Transactions Active, Adding and Editing Reports, Adding and Editing Reports
@subsection Expansion Formats
@cindex report, custom variable

It is sometimes convenient to leave room to customize a report without
saving the command line every time.  For example running a register
report for a specific account, enter at runtime by the user.  The
built-in report @var{account} does exactly that, using a variable
expansion to prompt the user for the account to use.  There are four
variables that can be expanded to run a report:

@table @var

@item ledger-file
Returns the file to be operated on.

@item payee
Prompts for a payee.

@item account
Prompt for an account.

@c FIXME : is it 'value' or 'tag' for '@item value' just below?
@item value
Prompt for a tag value.

@end table

You can use these expansion values in your ledger report commands.  For
example, if you wanted to specify a register report the displayed
transactions from a user-determined account with a particular meta-data
tag value, you specify the following command line:

@example
ledger -f %(ledger-file) reg %(account) \
  --limit \"tag('my-tag') =~/%(value)/\"
@end example

Note how the double-quotes are escaped with back-slashes.

@node Make Report Transactions Active,  , Expansion Formats, Adding and Editing Reports
@subsection Make Report Transactions Active
@cindex report, custom command

In a large register report it is convenient to be able to jump to the
source transaction.  Ledger-mode will automatically include source
information in every register file that doesn't contain
a @option{--subtotal} option. It does this by adding
@option{--prepend-format='%(filename):%(beg_line):'} to the register
report command-line you specify.  You should never have to see this, but
if there is an error in your ledger output this additional information
may not get stripped out of the visible report.

@node Reversing Report Order,  , Adding and Editing Reports, The Report Buffer

@cindex report, order reversing

Often, banks show their on-line transaction histories with the most
recent transaction at the top.  Ledger itself cannot do a sensible
ledger report in reverse chronological order, if you sort on reverse
date the calculation will also run in the opposite direction.  If you
want to compare a ledger register report to a bank report with the most
recent transactions at the top, type @kbd{R} in the @file{*Ledger

maintain the proper mathematical sense.
