Since Nikola already supported HTML, reStructuredText and Markdown, adding a couple more is not very difficult. Here's how:
[Core] Name = textile Module = compile_textile [Documentation] Author = Roberto Alsina Version = 0.1 Website = http://nikola.ralsina.com.ar Description = Compile Textile into HTML
Then you need to create a python module called (in this case) compile_textile.py
The compile_html method takes two arguments, one file from which it reads the markup, and one to write HTML. Example:
def compile_html(self, source, dest): if textile is None: raise Exception('To build this site, you need to install the "textile" package.') try: os.makedirs(os.path.dirname(dest)) except: pass with codecs.open(dest, "w+", "utf8") as out_file: with codecs.open(source, "r", "utf8") as in_file: data = in_file.read() output = textile(data, head_offset=1) out_file.write(output)
Make sure to use utf8 everyhere.
The create_post function is used to create a new, empty, post with some metadata in it. Example:
def create_post(self, path, onefile=False, title="", slug="", date="", tags=""): with codecs.open(path, "wb+", "utf8") as fd: if onefile: fd.write('<notextile> <!--\n') fd.write('.. title: %s\n' % title) fd.write('.. slug: %s\n' % slug) fd.write('.. date: %s\n' % date) fd.write('.. tags: %s\n' % tags) fd.write('.. link: \n') fd.write('.. description: \n') fd.write('--></notextile>\n\n') fd.write("\nWrite your post here.")
The metadata has to be in the form ".. fieldname: fieldvalue" and usually needs to be wrapped in a comment so that it's not shown in the output.
The onefile parameter means you have to write that metadata in the post. If it's False, you don't.
In some rare cases (Creole, I am looking at you) comments are not supported and you should raise an exception if onefile is True.
And that's it, markup support is fairly easy to add as long as there is a python implementation of a function to convert markup into html.
