Hi Stephen,
The %!postvoodoo does not execute system commands, as you tried to do.
It's very similar to the %!postproc filter: accepts two arguments,
doing search and replace on the output. The only difference is that
you can replace multiple lines at once, since the entire output is
handled as a single string.
Usage:
%!postvoodoo: search_regex replace_text
More info, from the txt2tags source code:
Your entire output document will be put in a single string, to your
search/replace pleasure. Line breaks are single \n's in all platforms.
You can change multiple lines at once, or even delete them. This is the
last txt2tags processing in your file. All %!postproc's were already
applied. It's the same as:
$ txt2tags myfile.t2t | postvoodoo
Your regex will be compiled with no modifiers. The default behavior is:
^ and $ match begin/end of entire string
. doesn't match \n
\w is not locale aware
\w is not Unicode aware
You can use (?...) in the beginning of your regex to change behavior:
(?s) the dot . will match \n, so .* will get everything
(?m) the ^ and $ match begin/end of EACH inner line
(?u) the \w, \d, \s and friends will be Unicode aware
You can also use (?smu) or any combination of those.
