Docs

hledger’s documentation structure

“There is a secret that needs to be understood in order to write good software documentation: there isn’t one thing called documentation, there are four. They are: tutorials, how-to guides, explanation and technical reference. They represent four different purposes or functions, and require four different approaches to their creation.” –[Daniele Procida] (https://news.ycombinator.com/item?id=21289832)

2019: out of date, needs update.

Project documentation lives in a number of places:

• site/*.md is the hledger.org website content, which is generated with hakyll[-std] and pandoc
• haddock documentation in the code appears on Hackage
• short blurbs: cabal files, module headers, HCAR, GSOC project, ..
• doc/notes.org has some old developer notes
• developer reports (profiles, benchmarks, coverage..) in doc/profs, sometimes published at hledger.org/profs
• https://github.com/simonmichael/hledger/tree/master/doc

site/ is now a symlink to the separate hledger_site repo.

See also Shake.hs.

hledger doc files can be divided into several groups:

1. Project admin/dev notes not published on the website. These are kept in this directory (doc/). They include:

   doc/finance/      project finances
   doc/hcar/         Haskell Community and Activities Report entries
   doc/lib.m4        common macros used in package manuals
   doc/manpage.*     misc. templates for rendering package manuals
   doc/mockups/      exploratory developer mockups   
   doc/profs/        a place for long-term profiling/performance data
   

2. Project doc files required to be in the top directory:

   README.md         the main project readme, displayed on github
   LICENSE           the default project license
   

3. Code/API docs in haskell source files as haddock comments:

   hledger*/**/*.hs  haddock module and function docs in most source files
   

4. Per-package descriptions, readmes, changelogs, and reference manuals. These are in the respective package directories:

   hledger*/package.yaml    source for package metadata (description, etc.)
   hledger*/README          package readme, displayed on hackage
   hledger*/CHANGES         package changelog, displayed on hackage
   hledger*/hledger*.m4.md  package manual source file(s)
   

5. The project website and additional docs - home page, FAQ, tutorials, how-tos, developer guide, etc. These are in the site directory:

   site/             hledger.org website content, templates, assets
   

Workflows

Last updated: 2025-09

Compile the Shake script

Shake.hs automates some doc maintenance tasks (complementing Justfile). Most contributors don’t need to use it, but if you do, compile it like so: in the hledger repo, run:

$ ./Shake.hs

Update options help

Edit general options definitions in hledger/Hledger/Cli/CliOptions.hs and command options definitions in hledger/Hledger/Cli/Commands/*.hs.

Update manuals’ content

Updates and fixes for the manuals’ content are welcome and encouraged! They can be committed together with related code changes, or separately.

The manuals have (a) source files, kept in the hledger repo and (b) generated files derived from those. Don’t edit the generated files, such as: - hledger/hledger.md or hledger-ui/hledger-ui.md in the hledger repo - site/src/1.50/hledger*.md or site/src/dev/hledger*.md in the hledger_site repo

Instead, edit the source files: - hledger/hledger.m4.md or hledger/Hledger/Cli/Commands/*.md for the hledger manual - hledger-ui/hledger-ui.m4.md for the hledger-ui manual - hledger-web/hledger-web.m4.md for the hledger-web manual.

(There are a few more source files which change less often; if you click “edit this page” on a recent release manual on the website, you’ll see all source files listed.)

Update manuals’ generated files

Contributors don’t need to do this; usually it’s done periodically by the maintainer. It requires unix tools such as m4, makeinfo and pandoc.

In the hledger repo: first, set current year and month for the man pages:

$ just mandates

Then update the lists of command line options in the manuals’ source files (only as needed, if command line options or option help have changed):

$ stack build && ./Shake cmddocs -c

Then regenerate the text, man, info, and markdown manuals in hledger*/ from their source files:

$ ./Shake manuals -c

Update dev manuals on the website

When updates to manuals’ generated files land in the master branch of the hledger repo on github, the dev manuals on hledger.org will update automatically.

(The manuals on the website are rendered from site/src/VERSION/*.md in the hledger_site repo, which are symlinked copies of hledger/hledger.md, hledger-ui/hledger-ui.md and hledger-web/hledger-web.md in the hledger repo.)

Update release manuals on the website

Contributors can do this, but doing it the right way is a little complicated; you can also ask the maintainer to do it.

The release manuals on the website are rendered from site/src/1.50/*.md, site/src/1.43/*.md, etc. These are generated as follows:

In the hledger repo, with the hledger_site repo symlinked as ./site;
for each major release REL that needs updating:

1. Cherry pick the manuals’ content updates for REL (not generated files updates) from master to REL-branch
2. In master, run just site-manuals-snapshot REL to update the release manuals in the site repo.

When these commits land in the hledger_site repo on github, the release manuals on hledger.org will update automatically.

Update hledger binaries with latest docs

This ensures the hledger dev executables are embedding the latest manuals’ generated files, affecting: - options help displayed by --help - command docs displayed by CMD --help - manuals displayed by help, --info, and --man.

Update the options help, manuals’ content and manuals’ generated files as above, then rebuild:

$ stack build

A quick heads-up: I am feeling like stepping back from github wiki, and reorganising our docs like so:

Two repos:

1. hledger - code and hard docs

• code and code docs (haddock docs & doctest examples)
• developer docs (READMEs in md or org format)
• product manuals (hledger/hledger.m4.md)
• release notes and announcements
• HCAR entries

2. hledger-site - website and soft docs

• hledger.org content, resources, site infrastructure
• user cookbook, how-tos, articles
• links to blog posts, discussions etc.
• other resources relating to our web presence/marketing

If you disagree, let’s discuss. Some quick considerations:

• moving docs to the wiki hasn’t affected the contribution rate
• using the wiki increases our dependence on github and makes our work less self-contained and future-proof
• the wiki docs don’t look great, aren’t very flexible, & don’t integrate well with our site & static docs
• using two docs systems increases complexity
• dev docs in the wiki are too far from the code, and compete with READMEs

PS:

• Why not go back to just one repo for everything ? Or if two repos, why not put all docs in one of them ?

Dev docs are most discoverable and maintainable right there in the main repo, ie as READMEs. Likewise for API docs (haddocks) and the reference manuals (hledger/hledgerm4.md). We want all of these updated in lock step with code/tooling changes.

Other (“soft”) docs are needed, but these have a more relaxed process, schedule, and scope (eg bookkeeping advice). They occasionally generate a lot of noise in the commit log, and I think it’s a good to keep that out of the code history. The website (home and other pages, site design, site infrastructure) generates similar commit storms and is somewhat independent of code, so it goes in the soft docs repo too.

These are my thoughts, but I have an open mind if you see a better way.

10/27/18 Still plenty of time to discuss and reconsider, but see also https://github.com/simonmichael/hledger/issues/920 https://github.com/simonmichael/hledger/issues/921

I’ll probably make a start on the first one (consolidating dev docs in main repo).
