This is one of two collections of maintainer/developer scripts; Makefile is the other.
This one, based on shake, provides a stronger programming language and
more platform independence. It requires stack and will auto-install
the haskell packages above when needed.
Some of the commands below require additional command-line tools, including:
- GNU date (on mac: brew install coreutils)
- groff
- m4
- makeinfo
- pandoc
- sed
Some things that may be useful when working on this:
- https://docs.haskellstack.org/en/stable/GUIDE/#script-interpreter
- watch Shake.hs for compile errors: make ghcid-shake
- load Shake.hs in GHCI: make ghci-shake
- rebuild things when files change with entr (file watcher), eg:
find hledger-lib hledger | entr ./Shake manuals
- view rule dependency graph:
./Shake --report, open report.html?mode=rule-graph&query=!name(/(doc%7Cimages%7Cjs%7Ccss%7Cfonts%7Ctime%7Capi%7Cui%7Ccsv)/)
