Purpose

This is a place to post snippets that are clever and/or useful.

Banner Comment

This generates a banner comment that spans the distance between the current column and the edge column (which I have set at 80).

banner = [[/%<string.rep("*", buffer.edge_column - buffer.column[buffer.current_pos] - 1)>
 * %0
 %<string.rep("*", buffer.edge_column - buffer.column[buffer.current_pos] - 2)>/]],

Include Guard

Generates an inclusion Guard for C/C++ header files. Defaults to the file's name without its extension and capitalized.

incguard = [[#ifndef %1(%<(buffer.filename or ''):match('[^/]*$'):upper():match('^[^%.]+')>)_H
#define %1_H
%0
#endif
]]

TA12: convert hyphens to underscores

With the syntax introduced in TextAdept 12, converting hyphens in a field to underscores looks like this:

hypopt = [[
cmdopt='--{1:long-opt}, var='${1/-/_/g}'
]]
