# Makefile.targ: common targets.
#
# NOTE: This makefile comes from the "eng" repo. It's designed to be dropped
# into other repos as-is without requiring any modifications. If you find
# yourself changing this file, you should instead update the original copy in
# eng.git and then update your repo to use the new version.
#
# This Makefile defines several useful targets and rules. You can use it by
# including it from a Makefile that specifies some of the variables below.
#
# Targets defined in this Makefile:
#
# check Checks JavaScript files for lint and style
# Checks bash scripts for syntax
# Checks SMF manifests for validity against the SMF DTD
#
# clean Removes built files
#
# docs Builds restdown documentation in docs/
#
# prepush Depends on "check" and "test"
#
# test Does nothing (you should override this)
#
# xref Generates cscope (source cross-reference index)
#
# For details on what these targets are supposed to do, see the Joyent
# Engineering Guide.
#
# To make use of these targets, you'll need to set some of these variables. Any
# variables left unset will simply not be used.
#
# BASH_FILES Bash scripts to check for syntax
# (paths relative to top-level Makefile)
#
# CLEAN_FILES Files to remove as part of the "clean" target. Note
# that files generated by targets in this Makefile are
# automatically included in CLEAN_FILES. These include
# restdown-generated HTML and JSON files.
#
# DOC_FILES Restdown (documentation source) files. These are
# assumed to be contained in "docs/", and must NOT
# contain the "docs/" prefix.
#
# JSL_CONF_NODE Specify JavaScriptLint configuration files
# JSL_CONF_WEB (paths relative to top-level Makefile)
#
# Node.js and Web configuration files are separate
# because you'll usually want different global variable
# configurations. If no file is specified, none is given
# to jsl, which causes it to use a default configuration,
# which probably isn't what you want.
#
# JSL_FILES_NODE JavaScript files to check with Node config file.
# JSL_FILES_WEB JavaScript files to check with Web config file.
#
# SMF_MANIFESTS XML files to check for validity using the SMF DTD.
#
# You can also override these variables:
#
# BASH Path to bash (default: bash)
#
# JSL Path to JavaScriptLint (default: "jsl")
#
# JSL_FLAGS_NODE Additional flags to pass through to JSL
# JSL_FLAGS_WEB
# JSL_FLAGS
#
# JSSTYLE Path to jsstyle (default: jsstyle)
#
# JSSTYLE_FLAGS Additional flags to pass through to jsstyle
#
#
# Defaults for the various tools we use.

# Targets. For descriptions on what these are supposed to do, see the
# Joyent Engineering Guide.
#
# These recipes make heavy use of dynamically-created phony targets. The parent
# Makefile defines a list of input files like BASH_FILES. We then say that each
# of these files depends on a fake target called filename.bashchk, and then we
# define a pattern rule for those targets that runs bash in check-syntax-only
# mode. This mechanism has the nice properties that if you specify zero files,
# the rule becomes a noop (unlike a single rule to check all bash files, which
# would invoke bash with zero files), and you can check individual files from
# the command line with "make filename.bashchk".

# The "docs" target is complicated because we do several things here:
#
# (1) Use restdown to build HTML and JSON files from each of DOC_FILES.
#
# (2) Copy these files into $(DOC_BUILD) (build/docs/public), which
# functions as a complete copy of the documentation that could be
# mirrored or served over HTTP.
#
# (3) Then copy any directories and media from docs/media into
# $(DOC_BUILD)/media. This allows projects to include their own media,
# including files that will override same-named files provided by
# restdown.
#
# Step (3) is the surprisingly complex part: in order to do this, we need to
# identify the subdirectories in docs/media, recreate them in
# $(DOC_BUILD)/media, then do the same with the files.
