# Version numbers
|
|
|
|
|
|
|
|
|
|
Some places version numbers appear:
|
|
|
|
|
|
|
|
|
|
- --version (and sometimes --help) output of all hledger* executables
|
|
|
|
|
- web manuals on hledger.org
|
|
|
|
|
- download page
|
|
|
|
|
- changelogs
|
|
|
|
|
- release notes
|
|
|
|
|
- release announcements
|
|
|
|
|
- hackage/stackage uris
|
|
|
|
|
- cabal tarball filenames
|
|
|
|
|
- platform-specific packages
|
|
|
|
|
|
|
|
|
|
Some old version numbering goals:
|
|
|
|
|
|
|
|
|
|
1. automation, robustness, simplicity, platform independence
|
|
|
|
|
2. cabal versions must be all-numeric
|
|
|
|
|
3. release versions can be concise (without extra .0's)
|
|
|
|
|
4. releases should have a corresponding VCS tag
|
|
|
|
|
5. development builds should have a precise version appearing in --version
|
|
|
|
|
6. development builds should generate cabal packages with non-confusing versions
|
|
|
|
|
7. there should be a way to mark builds/releases as alpha or beta
|
|
|
|
|
8. avoid unnecessary compiling and linking
|
|
|
|
|
9. minimise VCS noise and syncing issues (commits, unrecorded changes)
|
|
|
|
|
|
|
|
|
|
Current version numbering policy:
|
|
|
|
|
|
|
|
|
|
- We (should) follow <https://haskell.org/haskellwiki/Package_versioning_policy>
|
|
|
|
|
|
|
|
|
|
- The "full release version" is ma.jor.minor, where minor is 0 for a
|
|
|
|
|
normal release or 1..n for bugfix releases. Each component is a
|
|
|
|
|
natural number (can be >= 10). Eg: 1.13 major release, 1.13.1
|
|
|
|
|
bugfix release.
|
|
|
|
|
|
|
|
|
|
- The "release version", which we prefer to use when possible, is
|
|
|
|
|
just ma.jor when minor is 0. Ie elide the dot zero.
|
|
|
|
|
|
|
|
|
|
- The build version is ma.jor.minor+patches, where patches is the number
|
|
|
|
|
of patches applied in the current repo since the last release tag.
|
|
|
|
|
|
|
|
|
|
- `hledger --version` shows the release version or build version as
|
|
|
|
|
appropriate.
|
|
|
|
|
|
|
|
|
|
- Release tags in the VCS are like PKG-VERSION. Eg hledger-1.13,
|
|
|
|
|
- hledger-ui-1.13.1.
|
|
|
|
|
|
|
|
|
|
Current process:
|
|
|
|
|
|
|
|
|
|
- In each hledger package directory there's a `.version` file
|
|
|
|
|
containing its desired version number.
|
|
|
|
|
|
|
|
|
|
- After changing a `.version` file: run `./Shake setversion` to
|
|
|
|
|
propagate the versions to all other places in the packages where
|
|
|
|
|
they should appear. This is not perfect (see Shake.hs) so review and
|
|
|
|
|
manually adjust the proposed changes before committing. Those
|
|
|
|
|
places include (you can also run these rules individually):
|
|
|
|
|
|
|
|
|
|
- `PKG/package.yaml` contains the cabal package version declaration,
|
|
|
|
|
bounds on other hledger packages, and a CPP VERSION macro used in
|
|
|
|
|
`hledger/Hledger/Cli/Version.hs`. Changes in package.yaml will be
|
2024-04-24 21:39:07 +03:00
|
|
|
propagated to `PKG/PKG.cabal` on the next stack build or --dry-run build
|
|
|
|
|
or with `just cabalfiles`.
|

|
|
|
|
|
|
|
|
- `PKG/.version.m4` contains the _version_ macro used in documentation source files (*.m4.md). It is updated by `./Shake setversion`.
|
|
|
|
|
|
|
|
|
|
- `PKG/.date.m4` contains the _monthyear_ macro used in man pages. It is updated by `./Shake manuals`.
|
|
|
|
|
|
|
|
|
|
- At release time:
|
|
|
|
|
|
|
|
|
|
- `./Shake PKG/CHANGES.md-finalise` converts the topmost heading, if
|
|
|
|
|
it is an interim heading (just a commit hash), to a permanent
|
|
|
|
|
heading containing the version and today's date.
|
|
|
|
|
|
|
|
|
|
- for each package being released, a PKG-VERSION git tag is created.
|
|
|
|
|
|
|
|
|
|
- At major release time:
|
|
|
|
|
|
|
|
|
|
- A new snapshot of the reference docs is added to the website, by
|
|
|
|
|
`./Shake site/doc/VERSION/.snapshot`, and added to the links in
|
|
|
|
|
`site/js/site.js`.
