This is a very brief README, since things are just beginning and still very much in flux. First, this document assumes the use of SBCL for now. Other implementations will be tested soon. * Installation The first thing to do is install the prerequisites. You may do this quite easily using asdf-install (note that if Hunchentoot gives you compilation error on the file port-sbcl, just select the restart for ACCEPT): $ sbcl * (require 'asdf-install) * (asdf-install:install :cl-ppcre) * (asdf-install:install :local-time) * (asdf-install:install :series) * (quit) Now you need to pull all of the projects relating to Ledger: $ git submodule init $ git submodule update The next step is to configure SBCL so it knows where to load ledger from. Create a file called ~/.sbclrc and add these contents: ;; -*- lisp -*- (mapc 'require '(asdf asdf-install)) (push "/path/to/cl-ledger/" asdf:*central-registry*) (dolist (project '("red-black/" "cambl/" "periods/")) (push (merge-pathnames project "/path/to/cl-ledger/") asdf:*central-registry*)) Make sure you change /path/to/cl-ledger/ to be the directory where CL-Ledger lives. Also, be sure this pathname ends with a slash! In CL, directory names always end with/ Now you can run Ledger at the REPL like this: $ sbcl * (require 'asdf) * (asdf:oos 'asdf:load-op :cl-ledger) This compiles and loads the Ledger core, and also the textual parser package, for parsing standard Ledger text files (other parser packages soon to come). * Basic commands Once in the REPL, try out this command: * (ledger:register-report "/path/to/cl-ledger/doc/sample.dat") You should see a register printed representing the contents of sample.dat. You can constrain this report using keyword modifiers: * (ledger:register-report "/path/to/cl-ledger/doc/sample.dat" :account "books") Ledger only reads the file past on the first run, and if it changes, so feel free to repeat the same command several times even for large journal filse. The following reports are supported: * (ledger:register-report "/path/to/cl-ledger/doc/sample.dat" [OPTIONS]) * (ledger:balance-report "/path/to/cl-ledger/doc/sample.dat" [OPTIONS]) * (ledger:print-report "/path/to/cl-ledger/doc/sample.dat" [OPTIONS]) * (ledger:equity-report "/path/to/cl-ledger/doc/sample.dat" [OPTIONS]) * (ledger:derive-entry "/path/to/cl-ledger/doc/sample.dat" [OPTIONS]) As for OPTIONS, any of the following keyword pairs is allowed. There are some extra options allowed for `derive-entry', for which please see below. :account "REGEXP" :not-account "REGEXP" :payee "REGEXP" :not-payee "REGEXP" :note "REGEXP" :not-note "REGEXP" :begin "YYYY/MM/DD" :end "YYYY/MM/DD" :range "RANGE EXPRESSION" ; a range expression, like "this month" :period "PERIOD EXPRESSION" ; like "every month this year" :expr "VALUE-EXPR" ; most Ledger 2.x value exprs allowed :limit "VALUE-EXPR" ; the same as 2.x's --limit or -l ; this is a convenience alias for :expr :only "VALUE-EXPR" ; the same as 2.x's --only :display "VALUE-EXPR" ; the same as 2.x's -d or --display :status KEYWORD ; only report transactions whose status ; is :CLEARED, :PENDING or :UNCLEARED :sort "VALUE-EXPR" ; sort based on VALUE-EXPR calculation :no-total BOOL ; don't show totals :collapse BOOL ; collapse multiline entries :subtotal BOOL ; group all transactions by account :invert BOOL ; negate all transaction values ; (same as saying :amount "-a") :related BOOL ; show "other" transactions of each entry :lots BOOL ; show all commodity lot information :lot-prices BOOL ; show commodity lot prices :lot-dates BOOL ; show commodity lot dates :lot-tags BOOL ; show commodity lot tags :amount "VALUE-EXPR" ; use EXPR to display transaction amounts :total "VALUE-EXPR" ; use EXPR to display the running total :set-amount "VALUE-EXPR" ; instead of :amount, actually represent ; the amount using EXPR (this is rarely ; something you want to do) :set-total "VALUE-EXPR" ; same for the running total :bridge-totals BOOL ; if the running totals are not contiguous ; create revaluation entries to fill gaps :show OUTPUT-MODE ; show amounts and totals using the given mode :show :market ; .. in terms of their market value :show :basis ; .. in terms of their basis cost Here's a quick table for translating Ledger 2.6.1 options into their corresponding CL-Ledger keywords: Short option Long option CL-Ledger keyword ------------ -------------------- --------------------- -b ARG --begin ARG :begin ARG -e ARG --end ARG :end ARG -p ARG --period ARG :period ARG -l ARG --limit ARG :limit ARG --only ARG :only ARG -d ARG --display ARG :display ARG -n :no-total t <-- for balances -n --collapse :collapse t -r --related :related t -s --subtotal :subtotal t -S EXPR --sort ARG :sort ARG --sort-entries ARG :sort-entries ARG -t EXPR * Options to `derive-entry' The reporting command `derive-entry' takes some special options. Here is the docstring for derive-entry: The DERIVE-ENTRY report uses Ledger to intelligently create a new entry for you. The possible keywords arguments are: :DATE <DATE-STRING> :PAYEE <REGEXP> :ACCOUNT <REGEXP> :BALANCE-ACCOUNT <REGEXP> :AMOUNT <VALUE-STRING> :APPEND <BOOLEAN> Except for :PAYEE, all of these keyword arguments are optional. Here is what they mean: :PAYEE REGEXP Find the most recent entry whose payee matches REGEXP, and base the new entry derivation on its details. If no matching entry can be found, the payee of the newly created entry will exactly match REGEXP. :DATE DATE-STRING The date of the new entry will be DATE-STRING, otherwise it is today. :ACCOUNT REGEXP Set the first account line in the new entry to be the most recently used account which matches REGEXP. If no such account can be found, an account named REGEXP is used. If no account is specified, the account "Expenses:Unknown" is used. :BALANCE-ACCOUNT REGEXP Like :ACCOUNT, except this refers to the account used for the second transaction in the newly derived entry. If not specified, a calculated "balance account" is looked for in the matching entry; if this does not apply, the journal's default account is used; if this does not apply, the account "Asets:Unknown" is used. :AMOUNT VALUE-STRING The amount of the first transaction. If it has no commodity, the correlated commodity from the discovered entry is used. :APPEND BOOLEAN If non-NIL, the new entry is written to the same journal where the matching entry was found (for a binder that references many journals, this is whichever file the discovered entry was in). Here are a few examples, using sample.dat as a reference: (ledger:derive-entry "doc/sample.dat" :payee "book") => 2007/12/04 Book Store Expenses:Books $20.00 Liabilities:MasterCard (ledger:derive-entry :payee "book" :amount "$125") => 2007/12/04 Book Store Expenses:Books $125.00 Liabilities:MasterCard (ledger:derive-entry :payee "Hello World") => 2007/12/04 Hello World Expenses:Unknown Assets:Unknown (ledger:derive-entry :date "2004/01/01" :payee "Hello World") => 2004/01/01 Hello World Expenses:Unknown Assets:Unknown (ledger:derive-entry :payee "book" :account "equ") => 2007/12/04 Book Store Equity:Opening Balances $20.00 Liabilities:MasterCard (ledger:derive-entry :payee "book" :account "Who Knows") => 2007/12/04 Book Store Who Knows $20.00 Liabilities:MasterCard (ledger:derive-entry :payee "book" :balance-account "bank") => 2007/12/04 Book Store Expenses:Books $20.00 Assets:Bank:Checking (ledger:derive-entry :payee "book" :account "liab" :balance-account "bank") => 2007/12/04 Book Store Liabilities:MasterCard $-20.00 Assets:Bank:Checking (ledger:derive-entry :payee "book" :account "bank" :amount 50) => 2007/12/04 Book Store Assets:Bank:Checking $50.00 Liabilities:MasterCard (ledger:derive-entry :payee "book" :account "bank" :amount "$125") => 2007/12/04 Book Store Assets:Bank:Checking $125.00 Liabilities:MasterCard * Binder caching After the call to `read-binder', the variable `*last-binder*' contains the contents of what was read. From that point forward, if no binder or string is passed to the reporting function, they will assume you wish to report on the contents of `*last-binder*'. * Implementations status Here is how Ledger stands up against current Lisp implementations, in order of how frequently I use them: SBCL 184.108.40.206 WORKS LispWorks 5.02 Personal WORKS Allegro CL 8.1 Express Fails to compile CL-FAD (where is :OSI?) Clozure CL 2007-12-07 Fails to compile LOCAL-TIME OpenMCL 2007-07-22 Fails to compile LOCAL-TIME ECL 2007-12-07 Fails to compile SERIES ABCL 0.0.10 Fails to compile SERIES CLISP 2.43 Fails to compile RED-BLACK CMUCL 19d (2007-11) Fails to compile PERIODS GCL 2.6.7 <unable to build so far> * In closing That's it for now, expect more in this file as things progress! John Wiegley 2007/11/17 p.s. For fans of the SERIES library, you can apply `scan-transactions' or `scan-entries' to a binder/account/journal/entry in order to produce a SERIES of the corresponding type. Example: (collect (ledger:scan-transactions (ledger:read-journal "doc/sample.dat"))) => [a list of all transactions, in sequence, within sample.dat]
