why would you want this recipe ? You need to integrate markup sources into a scons based build system and you would like implicit dependencies for xi:include directives.
file SConscript:
import sys from markup.filters import IncludeFilter from markup.template import Template,TemplateLoader def markup_xinclude_scan(node, env, path, arg): t=Template(node.get_contents()) loader=TemplateLoader('.'.split()) t.filters.insert(0, IncludeFilter(loader)) t.generate().render() return loader._cache.keys() markup_scanner = Scanner( name='markup', function=markup_xinclude_scan, argument=None, skeys = '.xhtml .html .xml'.split()) scanners = Environment().Dictionary('SCANNERS') env = Environment(SCANNERS = scanners + [markup_scanner]) env.Command('page-out', 'page.html', './render $SOURCES $TARGET')
So, assuming page.html references another file, say base.html, using the Xinclude recipe, any edit to base.html will cause scons to consider page-out to be out of date. After an edit of either page.html or base.html scons -f SConscript will be sufficient to bring page-out up to date.
render is a trivial wrapper script that renders the final output using markup for a single source file. Mine looks like this:
#!/usr/bin/python import sys try: import wingdbstub except ImportError: pass from markup.filters import IncludeFilter from markup.template import Template,TemplateLoader t=Template(file(sys.argv[1]).read()) t.filters.insert(0, IncludeFilter(TemplateLoader('.'.split()))) outf = sys.stdout if len(sys.argv) > 2: outf=file(sys.argv[2], 'w') print >> outf, t.generate().render()
There may be slicker ways of doing this. If you know them then please update this recipe.
