LaTeX like macro for markdown
tl;dr: I made a simple macro system for my blog. Now I juste have to write %latex and it show as LaTeX.
I added a macro system for my blog system. When we are used to LaTeX this lack can be hard to handle. Particularly when using mathematical notations. In the header of my files I simply write:
macros: test: "This is a macro test" latex: '<span style="text-transform: uppercase">L<sup style="vertical-align: 0.15em; margin-left: -0.36em; margin-right: -0.15em; font-size: .85em">a</sup>T<sub style="vertical-align: -0.5ex; margin-left: -0.1667em; margin-right: -0.125em; font-size: 1em">e</sub>X</span>'
In the body it will replace every occurrence of:
- %test by This is a macro test,
- and %latex by LaTeX.
The source code is really simple.
For nanoc
user, simply put this file in your lib
directory.
# usage: # --- # ... # macros: # test: "passed test" # --- # ... # Here is a This is a macro test. # class Macros < Nanoc3::Filter identifier :falacy attr_accessor :macro def initialize(arg) super @macro={} @macro[:tlal] = %{<span class="sc"><abbr title="Trop long à lire">tlàl</abbr> : </span>} @macro[:tldr] = %{<span class="sc"><abbr title="Too long; don't read">tl;dr</abbr>: </span>} if @item.nil? if not arg.nil? @macro.merge!( arg ) end else if not @item[:macros].nil? @macro.merge!( @item[:macros] ) end end end def macro_value_for(macro_name) if macro_name.nil? or macro_name=="" or @macro[macro_name.intern].nil? return %{%#{macro_name}} end return @macro[macro_name.intern] end def run(content, params={}) content.gsub(/%(\w*)/) do |m| if m != '%' macro_value_for($1) else m end end end end
Macros could be very useful, read this article for example.
