How to...

(This is the README in the hledger repo's bin/ directory, also published as the Scripts and add-ons page on hledger.org.)

A script is a program you can run immediately without needing to compile it first. They are often small and defined in a single file or shell alias or shell function. You can create your own simple or complex scripts which enhance hledger. Eg you might script a complicated report so you don't have to remember the detailed command(s).

A hledger add-on command is any program whose name begins with "hledger-". Add-on commands found in PATH will appear in the commands list (shown when you run hledger with no arguments). Some of the scripts below are add-ons. Some add-ons are written in Haskell and can use hledger's full power, like builtin commands.

Below are some existing scripts you can use or learn from. Most of these are collected in hledger's bin/ directory, which you can get by cloning the hledger source. Compiled add-ons are also listed below, in their own section.

Note, you don't need any of these extras if you are new to hledger - except possibly hledger-ui and hledger-web, which can be nice to have at the start.

Here are some scripts which don't use hledger directly, but might be useful to hledger users. (For more, see also: plaintextaccounting.org > Software).

pricehist

pricehist is useful for downloading market prices / conversion rates; recommended. And hledger-pricehist is a small script to make it show up in the hledger commands list.

paypaljson

paypaljson downloads the last 30 days of Paypal transactions (requires a free developer account & API key).

paypaljson2csv

paypaljson2csv (python) converts paypaljson's output to CSV, with format similar to Paypal's manually-downloaded CSV.

hledger command line scripts

These scripts use hledger's command line interface, or process one of its output formats.

bashrc

bashrc contains many example bash aliases and functions. After installing the bin scripts: as a bash user,

# customise FINDIR and LEDGER_FILE at the top of bin/bashrc
$ . bin/bashrc
$ fin        # list the scripts available

ft

ft is a way to organise your finance-related reports and scripts using standard bash. (See also Justfile below.)

$ alias f=~/src/hledger/bin/ft
$ f
--------------------------------------------------------------------------------"; }
ft - finance tool: run financial reports and finance-related scripts

Justfile

https://github.com/casey/just is a nice tool for organising financial reports and scripts, similar to make, but more robust for this use case. I can recommend it. See also hledger and just.

Here is a Justfile reimplementing the ft and tt scripts more simply:

$ brew install just  # eg
$ alias j=just
$ cd ~/finance
$ cp ~/src/hledger/bin/Justfile .  # or start from scratch: just --init
$ j
Justfile commands:
    watch CMD                      # rerun the given command with watchexec whenever local files change
    get-csv                        # download auto-downloadable CSVs (paypal)
    import-dry                     # import new downloaded transactions to the main journal, dry run
    import                         # import new downloaded transactions to the journal, logging and not printing errors

watchaccounts

watchaccounts shows hledger account names, updating on file change under the current directory. Arguments are passed to the hledger accounts command. Useful when cleaning up accounts.

$ watchaccounts expenses -2
$ watchaccounts -f time.journal client1 date:thismonth -l

sortandmergepostings

sortandmergepostings is an adventuresome awk script intended to clean up and merge similar postings in a transaction (see original discussion). It sorts postings so that positive ones are first, negative ones last. Within each sign, postings are sorted alphabetically by account name. Lastly if there are multiple postings to the same account in the same direction, it tries to merge them (by leaving some amounts blank). Piping the output to hledger print can recalculate the missing amounts. Multiple runs might be needed to clean up all duplicates.

$ sortandmergepostings input.journal | hledger -f - print -x

hledger-simplebal

hledger-simplebal shows how to reliably report a single machine-readable number with hledger. This and the other "hledger-" scripts are add-on commands.

$ hledger simplebal

hledger-bar

hledger-bar prints quick bar charts in the terminal.

$ hledger bar reimbursement
2023-01	++++++
2023-02	++
2023-03	++
2023-04	-------

$ hledger bar                                        # show help
$ hledger bar food                                   # monthly food expenses
$ hledger bar -- 1 --count food                      # monthly food posting counts
$ hledger bar -- type:c not:tag:clopen cur:\\\\$ -W  # weekly cashflow, $ only
$ hledger bar -- type:al not:tag:clopen cur:\\\\$    # monthly net worth change ($)
$ hledger bar -- type:rx --invert cur:\\\\$          # monthly profit/loss ($)
$ hledger bar -- -v 1 -f $TIMELOG -D                 # daily hours, with numbers

hledger-git

hledger-git provides easy version control for your journal files, using git. Run it with no arguments for help.

$ hledger git log
$ hledger git status
$ hledger git record [MSG]

hledger-pijul

hledger-pijul provides the same thing using the pijul version control system..

$ hledger pijul log
$ hledger pijul status
$ hledger pijul record [MSG]

hledger-edit

The hledger-utils python package provides a hledger-edit command to edit the queried transactions in your $EDITOR no matter what file they reside in.

Install or upgrade:

$ pip install -U hledger-utils    # might be slightly different on your system

Examples:

# Opens your $EDITOR or $VISUAL with only costs in Florida 
# (if you named and tagged them like that)
# edit the transactions, save and exit your editor, 
# then the changes are distributed to the original files
$ hledger edit Cost tag:location=Florida

# Automate changes by setting `$EDITOR` to a script
# (here all food we had on that one day in Florida was Fast Food 🌭 and we initially forgot to write that) 
EDITOR='perl -pi -e "s|Cost:Food|Cost:Food:Fast Food|g"' hledger edit tag:location=Florida date:2022-12-20

hledger-plot

The hledger-utils python package provides a hledger-plot command for generating charts with matplotlib.

Install or upgrade:

$ pip install -U hledger-utils    # might be slightly different on your system

Examples:

$ hledger-plot -h
$ hledger plot -- bal -DH ^Assets -2

hledger-lots

hledger-lots shows a lots report, or generates a lot sale transaction, using FIFO strategy (and without needing subaccounts for lots).

Install or upgrade:

$ pip install -U hledger-lots

Examples:

$ hledger lots
$ hledger lots view
$ hledger lots list

hledger-report1.sh

hledger-report1.sh is a custom compound report done in shell. See also hledger-report1.hs.

hledger haskell scripts

These scripts are written in Haskell and use hledger's haskell API (by importing the hledger or hledger-lib haskell libraries). They are often stack scripts. They can do anything hledger's builtin commands can do, and are usually more robust than command line scripts. Some builtin commands were first developed as standalone haskell scripts.

hledger-script-example

hledger-script-example.hs is a template for writing your own hledger-integrated add-on command. It has the same structure as most of the add-ons here:

a stack script for robustness
providing command line help
accepting common hledger options

hledger-print-location

hledger-print-location.hs is a variant of hledger's print command that adds the file and line number to every transaction, as a tag:

$ hledger print-location -f hledger/examples/sample.journal desc:eat
2008/06/03 * eat & shop
  ; location: /Users/simon/src/hledger/examples/sample.journal:30
  expenses:food                  $1
  expenses:supplies              $1
  assets:cash

hledger-swap-dates

hledger-swap-dates.hs prints transactions with their date and date2 fields swapped.

hledger-check-tagfiles

hledger-check-tagfiles.hs interprets all tag values containing a / (forward slash) as file paths, and checks that those files exist. hledger-check-tagfiles.cabal.hs is the same command implemented as a cabal script rather than a stack script.

hledger-register-max

hledger-register-max.hs runs a register report and prints the posting with largest historical balance.

$ hledger-register-max -f examples/bcexample.hledger checking
2013-01-03 Hoogle | Payroll  Assets:US:BofA:Checking      1350.60 USD  8799.22 USD
$ hledger register-max -- -f examples/bcexample.hledger checking
2013-01-03 Hoogle | Payroll  Assets:US:BofA:Checking      1350.60 USD  8799.22 USD

hledger-check-postable

hledger-check-postable.hs check that no postings are made to accounts declared with a postable:n or postable:no tag. This can be used as a workaround when you must declare a parent account to control display order, but you don't want to allow postings to it. Eg, to allow postings to assets:cash but not assets (remember that account tags are inherited):

account assets         ; postable:n
account assets:cash    ; postable:

hledger-stockquotes fetches market prices. Not widely used, consider pricehist instead.
hledger-diff compares two journal files. It's now built in to hledger, so you don't need it.

How to...

Install scripts

To use these bin scripts you must ensure they are in your $PATH and runnable:

Shell scripts: you may need bash, or to adapt the scripts for your shell.
Python scripts: you'll need python 3 and pip.
Haskell scripts: you'll need stack. Or if you know how, you can make them cabal scripts, or install their dependencies manually and use runghc/ghc.

Here's a suggested install procedure:

# Go to wherever you keep financial files:
$ cd ~/finance

# Get the hledger repo
# the fast way, without version control:
$ curl -LOJ https://github.com/simonmichael/hledger/archive/refs/heads/master.zip && unzip hledger-master.zip && mv hledger-master hledger
# or the slow way, with version control for easy diffing/updating/contributing
# git clone https://github.com/simonmichael/hledger

# Make a more convenient symlink to the bin directory:
$ ln -s hledger/bin

# Add the bin directory to your PATH. Eg as a bash user:
$ echo "export PATH=$PATH:$PWD/bin" >>~/.bash_profile"
$ export PATH=$PATH:$PWD/bin

# Optionally, compile all haskell scripts for faster startup:
$ cd hledger; bin/compile.sh

# Optionally, install the python scripts:
$ pip install -U hledger-utils
$ pip install -U hledger-lots

# Check that hledger's command list now includes the bin scripts.
# Eg "check-fancyassertions" and "swap-dates" should be listed:
$ hledger

Create a new script

To create a new hledger-integrated script, copy hledger-script-example.hs. On unix, the new script should be marked executable. This should do it:

$ cd bin
$ cp hledger-script-example.hs hledger-cmd.hs   # replace cmd with your command name
# edit hledger-cmd.hs, updating at least the command name and help
$ stack install safe text     # ensure the script's dependencies are installed
$ hledger-cmd.hs --help
cmd [OPTIONS]
  My new cmd command.
  ...
$ stack ghc hledger-cmd.hs  # optionally compile for faster startup/durability
$ hledger cmd -- --help
cmd [OPTIONS]
  My new cmd command.
  ...

Run ghcid on a script

$ stack exec --package 'safe text' -- ghcid hledger-cmd.hs 
...
Ok, one module loaded.
All good (1 module, at 10:50:48)

Run ghci on a script

$ stack ghci --package 'safe text' hledger-cmd.hs 
...
Ok, one module loaded.
...
ghci>
