# Make A Makefile is provided to make common developer tasks easy to remember, and to insulate us a little from the ever-evolving Haskell tools ecosystem. Using it is entirely optional, but recommended. You'll need [GNU Make](https://www.gnu.org/software/make) installed. The Makefile contains a fair amount of obsolete cruft and needs cleanup. Some tasks (docs, website) are now handled by the [Shake](#shake) file instead. The Makefile is self-documenting. Run `make` to see a list of the main make rules: ```cli $ make Makefile:37: -------------------- hledger make rules -------------------- Makefile:39: make [help] -- list documented rules in this makefile. make -n RULE shows more detail. Makefile:204: (INSTALLING:) Makefile:206: make install -- download dependencies and install hledger executables to ~/.local/bin or equivalent (with stack) Makefile:231: (BUILDING:) Makefile:235: make build -- download dependencies and build hledger executables (with stack) Makefile:304: make hledgerdev -- quickly build the hledger executable (with ghc and -DDEVELOPMENT) ... ``` To see what a make rule will do without actually doing it, use the `-n` flag: ```cli $ make build -n stack build ``` ```cli $ make test -n (stack test \ && echo pkgtest PASSED) || echo pkgtest FAILED (stack exec hledger test \ && echo builtintest PASSED) || echo builtintest FAILED (COLUMNS=80 PATH=`pwd`/bin:/home/simon/src/hledger/bin:/home/simon/.local/bin:/home/simon/.cabal/bin:/opt/ghc/7.10.1/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/var/lib/gems/1.9.1/bin stack exec -- shelltest --execdir -- -j16 --hide-successes tests \ && echo functest PASSED) || echo functest FAILED ```
