SYNOPSIS

include <build.www.mk>

DESCRIPTION

The build.www.mk module generates a set of HTML documents (or code fragments), possibly in multiple language variants, from an HTML source file. The HTML source is processed by m4(1) macro processor in conjunction with the multi-language preprocessor mlproc(1). The following source types are recognized:

HTML4/HTML5 + M4 sources (*.htm)
M4 macro packages (*.m4)
JavaScript sources (*.js)
Cascading style sheets (*.css-in)

From those sources, build.www.mk is able to generate:

Minified HTML documents/fragments (*.html.<lang>)
Matching HTTP variant data (*.html.var)
Minified, translated JavaScript (*.<lang>.js)
Minified cascading style sheets (*.css)

TARGETS ↑

${HTML}	Source from which to generate HTML documents. The source may include M4 macro calls, multi-language "<ml>" tags, and "$_(gettext)" sequences (see mlproc(1) for details).
${JS}	JavaScript source files. The source is only fed through mlproc(1), and may include "$_(gettext)" sequences.
${CSS}	Source from which to generate cascading style sheets (may include M4 macro calls).
clean-www	Clean up the generated files.
cleandir-www	Clean up for packaging.
install-www	Install HTML documents to the target installation directory HTMLDIR,overwriting any existing document if HTML_OVERWRITE is Yes. If HTML_INSTSOURCE is Yes, all files needed for re-generating the documents are also installed into the target directory (including a Makefile).
deinstall-www	Uninstall documents from the installation directory.

VARIABLES ↑

HTML	Documents to generate and install. If multilingual support is not required, use the .html extension. Otherwise, specify the .html.var extension (documents will be generated for each combination of language and character set -- the .html.var file may then be used directly by Apache's mod_negotiation or equivalent).
M4	Path to the m4(1) macro processor.
M4FLAGS	Extra flags to pass to m4.
MINIFIER	Path to HTML/CSS minifier (such as html-minifier(1)).
MINIFIERFLAGS	Flags to minifier (for HTML).
MINIFIERFLAGSCSS	Flags to minifier (for CSS).
MLPROC	Path to the mlproc(1) preprocessor (part of BSDBuild).
MLPROCFLAGS	Arguments to mlproc(1). For gettext-style translation, the -L and -D arguments should be specified.
PERL	Path to the perl(1) interpreter.
ICONV	Path to the iconv(1) utility, needed to generate the character set variants.
BASEDIR	Directory containing the macro files (Default = "m4").
DTD	Insert at beginning of generated documents (default: "<!DOCTYPE html>").
TEMPLATE	Template to use for preprocessing the HTML source. It must reside in BASEDIR and use the .m4 extension.
CSS_TEMPLATE	Similarly to TEMPLATE,but used to preprocess CSS source.
LANGUAGES	Space-separated list of translations available for the documents specified in ${HTML}. See the section MULTI-LINGUAL SUPPORT for more details.
DEF_LANGUAGE	The default language.
CLEANFILES	Extra files to remove in the clean target.
HTMLDIR	Installation directory. The special value none indicates that the install operation should be a no-op (Default = "none").
HTML_OVERWRITE	Don't overwrite existing documents in the install phase (Default = "No").
HTML_INSTSOURCE	Install the HTML source, templates, JS/stylesheets and all other files needed to be able to re-generate the documents in the installation directory, including a Makefile. (Default = "Yes").

MULTI-LINGUAL SUPPORT ↑

The LANGUAGES variable specifies a list of languages in which the documents specified in HTML are available. If documents are fed to mlproc(1) (the default), they may contain translations enclosed in <ml> tags, like so:

	<ml lang="en">Hello</ml>
	<ml lang="fr">Bonjour</ml>

Sequences such as "$_(foo)" will also be translated using gettext(3) (see mlproc(1) for details).
