begindiv(intro)
|

|
|
<%= tldr %> I made a simple macro system for my blog. Now I juste have to write %<span></span>latex and it show as %latex.
|
|
|
|
enddiv
|
|
|
|
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:
|
|
|
|
<code class="yaml">
|
|
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>'
|
|
</code>
|
|
|
|
|
|
In the body it will replace every occurrence of:
|
|
|
|
- %<span></span>test by *%test*,
|
|
- and %<span></span>latex by *%latex*.
|
|
|
|
The source code is really simple.
|
|
For `nanoc` user, simply put this file in your `lib` directory.
|
|
|
|
<code class="ruby" file="macros.rb">
|
|
# usage:

# macros:

# test: "passed test"

# Here is a %test.

@macro.merge!( arg )

Macros could be very useful, read [this article](http://adam.gomaa.us/blog/2007/oct/22/markdown-doesnt-scale/index.html) for example.
