hledger: Make It So
What is it?
hledger-makeitso
is a command-line executable program that gives you a guided hledger workflow. It focuses on automated processing of electronic statements as much as possible, as opposed to manually adding your own hledger journal entries.
Manual entries are still possible, we just think it saves time in the long run to automatically process a statement whenever one is available.
It started when I realized that the scripts I wrote while playing around with the ideas in adept's Full-fledged Hledger isn't really specific to my own finances, and can be shared.
Overview of the Basic Workflow
- Save an input CSV file to a specific directory.
- Add an hledger rules file. Include some classification rules if you want.
- Run
hledger-makeitso import
Add all your files to your favourite version control system.
The generated journal that you most likely want to use as your LEDGER_FILE
is called all-years.journal
. This has include directives to all the automatically imported journals, as well as includes for your own manually managed journal entries.
In a typical software project we don't add generated files to version control, but in this case I think it is a good idea to add all the generated files to version control as well - when you inevitably change something, e.g. how you classify transactions in your rules file, then you can easily see if your change had the desired effect by looking at a diff.
Who should use this?
hledger-makeitso
is intended for you if:
- You are interested in getting started with hledger and you wouldn't mind pointers to the right docs along the way.
- You want a way to organise your finances into a structure that will be maintainable over the long term.
- You want to automate as much as possible when dealing with your financial life.
- You don't mind writing some scripts when needed, as long as it saves you time over the long term.
- You want the ability to model your entire financial life in one tool, as opposed to just the parts that some online tool currently supports.
- You appreciate the fact that all your financial information stays within your control.
How Stable is it?
We're not close to a 1.0 release yet, which means that we can still make changes if needed.
That being said, some parts have been used and tested extensively and are likely to remain stable. Have a look at the "Stability of this Feature" sections in the feature reference below.
I add future work, ideas and thoughts as Github issues and in TODO.org, so have a look there for more clues as to what may likely change.
Let me know if you can think of some improvements.
Detailed Step-By-Step Guide
Have a look at the detailed step-by-step instructions and the files in the documentation directory.

After Cloning This Repository
This repository has some submodules included, mostly related to the examples in the documentation.
You need to initialise and update the submodules:
git submodule init
git submodule update
Build Instructions
You need a recent version of stack installed.
Then run:
stack test
stack install
Which should end with this:
Copied executables to ~/.local/bin:
- hledger-makeitso
Ensure that ${HOME}/.local/bin
is in your PATH
.
Usually this means adding this to your ~/.bashrc
:
PATH="${HOME}/.local/bin:${PATH}"
Building with older Haskell Versions
To build using an older version of GHC and related dependencies, point stack to one of the other yaml files:
stack test --stack-yaml stack-8.4.4.yaml
stack test --stack-yaml stack-8.2.2.yaml
Feature Reference
Input Files
Your input files will probably be CSV files with a line for each transaction, although other file types will work fine if you use a preprocess
or a construct
script that can read them. These scripts are explained later.
We mostly use conventions based on a predefined directory structure for your input statements.
For example, assuming you have a savings
account at mybank
, you'll put your first CSV statement here: import/john/mybank/savings/1-in/2018/123456789_2018-06-30.csv
.
Some people may want to include accounts belonging to their spouse as part of the household finances: import/spouse/otherbank/checking/1-in/2018/987654321_2018-06-30.csv
.
More About Input Files
All files and directories under the import
directory is related to the automatic importing and classification of transactions.
The directory directly under import
is meant to indicate the owner or custodian of the accounts below it. It mostly has an impact on reporting. You may want to have separate reports for import/mycompany
and import/personal
.
Below the directory for the owner we can indicate where an account is held. For a bank account you may choose to name it import/john/mybank
.
If your underground bunker filled with gold has CSV statements linked to it, then you can absolutely create import/john/secret-treasure-room
.
Under the directory for the financial institution, you'll have a directory for each account at that institution, e.g. import/mycompany/bigbankinc/customer-deposits
and import/mycompany/bigbankinc/expense-account
.
Next you'll create a directory named 1-in
. This is to distinguish it from 2-preprocessed
and 3-journal
which will be auto-generated later.
Under 1-in
you'll create a directory for the year, e.g. 2018
, and within that you can copy the statements for that year: import/john/mybank/savings/1-in/2018/123456789_2018-06-30.csv
Stability of this Feature
The basic owner/bank/account/year structure has been used and tested fairly extensively, I don't expect a need for it to change.
I'm open to suggestions for improvement though.
Rules Files
If your input file is in CSV format, or converted to CSV by your preprocess
script, then you'll need an hledger rules file.
hledger-makeitso
will try to find a rules file for each statement in a few places. The same rules file is typically used for all statements of a specific account, or even for all accounts of the same specific bank.
- A global rules file for any
mybank
statement can be saved here:import/mybank.rules
- A rules file for all statements of a specific account:
import/spouse/bigbankinc/savings/bigbankinc-savings.rules
Statement-specific Rules Files
What happens if some of the statements for an account has a different format than the others?
This can happen if you normally get your statements directly from your bank, but some statements you had to download from somewhere else, like Mint, because your bank is being daft with older statements.
In order to tell hledger-makeitso
that you want to override the rules file for a specific statement, you need to add a suffix, separated by an underscore (_
) and starting with the letters rfo
(rules file override) to the filename of that statement.
For example: assuming you've named your statement 99966633_20171223_1844_rfo-mint.csv
.
hledger-makeitso
will look for a rules file named rfo-mint.rules
in the following places:
- in the import directory, e.g.
import/rfo-mint.rules
- in the bank directory, e.g.
import/john/mybank/rfo-mint.rules
- in the account directory, e.g.
import/john/mybank/savings/rfo-mint.rules
Example rules file usage
A common scenario is multiple accounts that share the same file format, but have different account1
directives.
One possible approach would be to include a shared rules file in your account-specific rules file.
If you are lucky enough that all statements at mybank
share a common format across all accounts, then you can include
a rules file that just defines the parts that are shared across accounts.
Two accounts at mybank
may have rules files similar to these.
A checking account at mybank:
# Saved as: import/john/mybank/checking/mybank-checking.rules
include ../../../mybank-shared.rules
account1 Assets:Current:John:MyBank:Checking
Another account at mybank:
# Saved as: import/alice/mybank/savings/mybank-savings.rules
include ../../../mybank-shared.rules
account1 Assets:Current:Alice:MyBank:Savings
Where import/mybank-shared.rules
may define some shared attributes:
skip 1
fields date, description, amount, balance
date-format %Y-%m-%d
currency $
Another possible approach could be to use your preprocess
script to write out a CSV file that has extra fields for account1
and account2
.
You could then create the above mentioned global import/mybank.rules
with the fields defined more or less like this:
fields date, description, amount, balance, account1, account2
Stability of this Feature
Rules files are a stable feature within hledger, and we're just using the normal hledger rules files. The account, bank and statement-specific rules files have been used and tested fairly extensively, I don't expect this to change.
Let me know if you think it should change.
Opening and Closing Balances
Opening Balances
hledger-makeitso
looks for a file named YEAR-opening.journal
in each account directory, where YEAR
corresponds to an actual year directory, eg. 1983 (if you have electronic statements dating back to 1983). Example: import/john/mybank/savings/1983-opening.journal
If it exists the file will automatically be included at the beginning of the generated journal include file for that year.
You need to edit this file for each account to specify the opening balance at the date of the first available transaction.
An opening balance may look something like this:
2018-06-01 Savings Account Opening Balance
assets:Current:MyBank:Savings $102.01
equity:Opening Balances:MyBank:Savings
Closing Balances
Similar to opening balances, hledger-makeitso
looks for an optional file named YEAR-closing.journal
in each account directory. Example: import/john/mybank/savings/1983-closing.journal
If it exists the file will automatically be included at the end of the generated journal include file for that year.
A closing balance may look something like this:
2018-06-01 Savings Account Closing Balance
assets:Current:MyBank:Savings $-234.56 = $0.00
equity:Closing Balances:MyBank:Savings
Example Opening and Closing Journal Files
As an example, assuming that the relevant year is 2019
and hledger-makeitso
is about to generate import/john/mybank/savings/2019-include.journal
, then one or both of the following files will be added to the include file if they exist:
import/john/mybank/savings/2019-opening.journal
import/john/mybank/savings/2019-closing.journal
The opening.journal
will be included just before the other included entries, while the closing.journal
will be included just after the other entries in that include file.
An include file may look like this:
cat import/john/mybank/savings/2019-include.journal
### Generated by hledger-makeitso - DO NOT EDIT ###
!include 2019-opening.journal
!include 3-journal/2019/123456789_2019-01-30
!include 2019-closing.journal
Stability of this Feature
The opening balances file works well in my opinion, I don't expect it to change. I'm only using closing balances in one or two places, so maybe that could do with some suggestions from people who use this more than myself.
The preprocess
Script
Sometimes the statements you get from your bank is less than suitable for automatic processing. Or maybe you just want to make it easier for the hledger rules file to do its thing by adding some useful columns.
If you put a script called preprocess
in the account directory, e.g. import/john/mybank/savings/preprocess
, then hledger-makeitso
will call that script for each input statement.
The preprocess
script will be called with 4 positional parameters:
- The path to the input statement, e.g.
import/john/mybank/savings/1-in/2018/123456789_2018-06-30.csv
- The path to an output file that can be sent to
hledger
, e.g.import/john/mybank/savings/2-preprocessed/2018/123456789_2018-06-30.csv
- The name of the bank, e.g.
mybank
- The name of the account, e.g.
savings
- The name of the owner, e.g.
john
Your preprocess
script is expected to:
- read the input file
- write a new output file at the supplied path that works with your rules file
- be idempotent. Running
preprocess
multiple times on the same files will produce the same result.
Stability of this Feature
Stable and tested.
The construct
Script
If you need even more power and flexibility than what you can get from the preprocess
script and hledger
's CSV import functionality, then you can create your own custom script to construct
transactions exactly as you need them.
At the expense of more construction work for you, of course.
As an example, hledger
's CSV import currently only supports two postings per transaction, even though hledger
itself is perfectly happy with transactions containing more than two postings, e.g.:
2019-02-01 Mortgage Payment
Liabilities:Mortgage $1000.00
Expenses:Interest:Real Estate $833.33
Assets:Cash -$1833.33
The construct
script can be used in addition to the preprocess
script, or on it's own. But since the construct
script is more powerful than the preprocess
script, you could tell your construct
script to do anything that the preprocess
script would have done.
Save your construct
script in the account directory, e.g. import/john/mybank/savings/construct
.
hledger-makeitso
will call your construct
script with 4 positional parameters:
- The path to the input statement, e.g.
import/john/mybank/savings/1-in/2018/123456789_2018-06-30.csv
- A "-" (indicating that output should be sent to
stdout
) - The name of the bank, e.g.
mybank
- The name of the account, e.g.
savings
- The name of the owner, e.g.
john
Your construct
script is expected to:
- read the input file
- generate your own
hledger
journal transactions - be idempotent. Running
construct
multiple times on the same files should produce the same result. - send all output to
stdout
.hledger-makeitso
will pipe your output intohledger
which will format it and save it to an output file.
Stability of this Feature
Stable and tested.
Manually Managed Journals
Not every transaction in your life comes with CSV statements.
Sometimes you just need to add a transaction for that time you loaned a friend some money.
hledger-makeitso
looks for pre-import
and post-import
files related to each generated include file as part of the import.
You can enter your own transactions manually into these files.
You can run hledger-makeitso import --verbose
to see exactly which files are being looked for.
As an example, assuming that the relevant year is 2019
and hledger-makeitso
is about to generate import/john/2019-include.journal
, then one or both of the following files will be added to the include file if they exist:
import/john/_manual_/2019/pre-import.journal
import/john/_manual_/2019/post-import.journal
The pre-import.journal
will be included just before the other included entries, while the post-import.journal
will be included just after the other entries in that include file.
An include file may look like this:
cat import/john/2019-include.journal
### Generated by hledger-makeitso - DO NOT EDIT ###
!include _manual_/2019/pre-import.journal
!include mybank/2019-include.journal
!include otherbank/2019-include.journal
!include _manual_/2019/post-import.journal
Stability of this Feature
It works, but the naming of _manual_
looks a bit weird. Should it be changed?
Compatibility with Ledger
When writing out the journal include files, hledger-makeitso
sorts the include statements by filename.
Ledger fails any balance assertions when the transactions aren't included in chronological order.
An easy way around this is to name your input files so that March's statement is listed before December's statement.
Another option is to add --permissive
to any ledger command.
So you should easily be able to use both ledger
and hledger
on these journals.
Project Goals
My hledger
files started to collect a bunch of supporting code that weren't really specific to my financial situation.
I want to extract and share as much as possible of that supporting code.
Adept's goals also resonated with me:
- Tracking expenses should take as little time, effort and manual work as possible
- Eventual consistency should be achievable: even if I can't record something precisely right now, maybe I would be able to do it later, so I should be able to leave things half-done and pick them up later
- Ability to refactor is a must. I want to be able to go back and change the way I am doing things, with as little effort as possible and without fear of irrevocably breaking things.
I've given a talk at Lambda Luminaries Johannesburg featuring hledger and hledger-makeitso.
FAQ
How does hledger-makeitso
differ from Full-fledged Hledger
?
Full-fledged Hledger is a brilliant system, and hledger-makeitso continues to learn much from it.
It has great documentation that does an excellent job of not only showing how things can be done, but also why it is such a great idea.
hledger-makeitso can be seen as a specific implementation of the Full-fledged Hledger system, with a few implementation details that are different.

---|---|
FFH describes itself as a tutorial with helper scripts that you can start using and adapt to your needs. | I started by following the FFH tutorial, and changed bits and pieces over time to suit my needs. The "owner/bank/account" structure for example. |
FFH is more open-ended: you can start with the basic scripts and over time turn it into something that solves your needs exactly. But you'll also end up with more code that you need to maintain yourself. | HMIS is less open-ended. For example, you have to adopt the "owner/bank/account" structure precisely as specified. But this allows HMIS to do more work for you. |
Maintaining include files are currently part of the user's responsibility. | HMIS generates flexible include files for you, and automatically includes opening/closing journals if the appropriately named files are present on disk. |
FFH actually generates some useful reports right now. HMIS still plans to get this done one day. | The "owner/bank/account" structure may look a bit much at first, but it allows us to run separate queries/reports for me/my spouse/my business etc and also allows for reports covering all of it in a an overall view. |
FFH chose scripts and build files that you can easily modify as you go along, but this requires a Haskell runtime to be installed everywhere it needs to run. The included docker image helps to make it less of an issue. | HMIS distributes a compiled binary. This means users or deployment targets don't need extra dependencies installed, they can just run a CLI program. This also provides a clearer distinction between what is provided, and what users need to do. |
The FFH build scripts requires familiarity with Haskell and the Shake build system. | Users may need to write preprocess or construct hooks, but in a language of their choice. |
Input files are assumed to always be CSV files. | HMIS de-empasises the need that input files must be in CSV format. Input files can be in any format that a preprocess or construct hook can read. |
