New language with asciidoc and dblatex
This post is to share how I was able to configure a new language with source highlight with asciidoc.
You will only need this if you have created a new language or you are writing about a language that dblatex doesn’t support.
In my case I have created a pseudo-code language to teach algorithm,
in portuguese. This is a simplified version of a language: if=SE,
else=SENAO, then=ENTAO, write=ESCREVA, read=LEIA. The ideia is to
highlight these keywords.
First let’s download a new copy of asciidoc:
$ cd ~
$ git clone https://github.com/asciidoc/asciidoc myasciidoc
Then we’re going to configure the new language dbalatex style.
To create a new language called “pseudo” add the following to
myasciidoc/dblatex/asciidoc-dblatex.sty:
\lstdefinelanguage{pseudo}
{
morekeywords={ENQUANTO,PARA,SE,SENAO,ENTAO},
morekeywords=[2]{LEIA,ESCREVA},
sensitive=true,
morecomment=[l]{//},
morecomment=[s]{/*}{*/},
morestring=[b]",
extendedchars=true,
keywordstyle=[2]{\color{black}\bfseries}
}
With the new language configured, the next step is to create
a test file (mylang_test.adoc):
== Testing new lang
[source,pseudo]
----
SE (x>2) ENTAO
ESCREVA "Alguma coisa"
SENAO
LEIA "Outra coisa"
----
The last step will be to generate the pdf with dbalatex and using the custom asciidoc:
$ myasciidoc/a2x.py -f pdf mylang_test.adoc
Here’s how the final pdf looks like:
