One of two project scripts files (Makefile, Shake.hs). This one
provides a stronger programming language and more platform
independence than Make. It requires stack and will auto-install the
haskell packages above when needed (on first run or when a new
resolver is configured in stack.yaml). Some rules below use additional
tools, including:
- groff
- m4
- makeinfo
- pandoc
- sed
- GNU date (on mac: brew install coreutils)
Compiling this script is recommended, to ensure required packages are
installed, minimise startup delay, and reduce sensitivity to the
current git state (eg when bisecting). To compile, run "./Shake.hs".
(Or "make Shake", or any other make rule depending on Shake).
Once compiled, run ./Shake without any arguments to list commands and
targets (see below).
When developing/troubleshooting this script, these are useful:
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)/)
