# One of two project scripts files (Makefile, Shake.hs).
# This one was a reboot of Makefile.old.
# It is probably used by hledger developers/contributors but not end-users.
# It requires GNU Make (https://www.gnu.org/software/make/).
# Also, some rules may require:
# - stack (http://haskell-lang.org/get-started, installs libs and runs ghc)
# - shelltestrunner (hackage, runs functional tests)
# - quickbench (hackage/stackage, runs benchmarks)
# - ghcid (hackage/stackage, recompiles and optionally runs tests on file change)
# - hasktags (hackage, generates tag files for code navigation)
# - profiterole (hackage/stackage, simplifies profiles)
# - profiteur (hackage/stackage, renders profiles as html)
# - hpack (hackage/stackage, generates cabal files from package.yaml files)
# - perl
#
# Kinds of hledger builds:
#
# - stack build: built with stack
#   (hledger/.stack-work/dist/ARCH/CABAL/build/hledger/hledger,
#   .stack-work/install/ARCH/SNAPSHOT/GHC/bin/hledger, installs to ~/.local/bin)
# - cabal (v1) build: built with cabal (and maybe a sandbox)
#   (hledger/dist/build/hledger/hledger, installs to ~/.cabal/bin)
# - ghc-only build: built quickly with ghc only, unoptimised, with DEVELOPMENT flag
#   (hledgerdev)
#
# This makefile mostly uses stack to get things done (slow but robust).
# It may sometimes (still ?) use ghc only, or cabal, when easier.

# see also: https://gmsl.sourceforge.io/

# XXX do we need this ?

# MAKEFILE HELP SYSTEM

# This defines the def-help* functions for generating makefile help
# (see the file for more details), and a "help" target (our default).
# Every useful rule in this makefile should use def-help to describe itself.
# "make" or "make help" will show these descriptions.
-include Makefile.helpsys

# Some calls and dummy targets to augment the default help output.
# Also, help-SUBSTR and SUBSTR-help targets to show only matching help.
