While taking a look at 3rd party libs, I flashed: why not use the output of my favorite editor, VIM? It has powerful syntax highlighting and a lot of syntax files. I can even use color schemes and some of VIM's settings, such as line numbering, to make my life easier (and it reads my
So instead of using simple tools, I went for the complicated solution. I made two script to help extracting HTML-formatted syntax and its associated CSS styles. Note that these scripts outputs their results on
stdout, so they won't alter your files.
Converting to HTML
highlight.sh outputs HTML-formatted syntax highlight of a file:
#/bin/bash OUTFILE=$(mktemp -t highlight) INFILE=$1 PARAM="set nonumber" if [ -z "$INFILE" ] then echo "usage: $0 source.file" exit fi vim +"$PARAM" \ +'let html_use_css=1' \ +'TOhtml' \ +'/<pre>/,/<\/pre>/d a' \ +'g/./d' \ +'1pu! a' \ +'$d' \ +"wq! $OUTFILE" \ +'q!' $INFILE &>/dev/null cat $OUTFILE && rm $OUTFILE
Try the script on itself:
$ bash highlight.sh highlight.sh
syntax.sh loads VIM's syntax test and outputs its generated CSS styles:
#!/bin/bash OUTFILE=$(mktemp -t syntax) vim +'so $VIMRUNTIME/syntax/hitest.vim' \ +'let html_use_css=1' \ +'TOhtml' \ +'v/^\./d' \ +"wq! $OUTFILE" \ +'q!' &>/dev/null cat $OUTFILE && rm $OUTFILE
Extract current vim colors as CSS:
$ bash syntax.sh
Currently, it's not the best way to integrate code into my posts. It's not automated and I need to manually insert the HTML. I've made an
awk script to help with this task. I'll post about it when it's integrated into my process.
