Hi,
While we are at the subject of tips for budding Vim scripters -
I had created this mapping -->
nmap com ^:if search('\/\*.*\*\/','c',line("."))!=0<CR>
:.s/\/\*\(.*\)\*\//\1/g<CR> :else<CR>
:.s/\(\s*\)\(.*\)\(\s*\)/\1\/\*\2\*\/\3/g<CR> :endif<CR> :noh<CR>
this command basically toggles C-style commenting on a line i.e. if the line
wasn't commented it comments out the entire line and vice-versa. I spent an
intense hour of exploring the help pages and plenty of effort in trial and
error before I could reach the 'Eureka' moment.
What I wanted to know is could the same functionality have been achieved by a
better sequence of commands? Can an experienced 'vimmer' do better?
Regards,
Sibin

Keep ff=unix . In other case your scripts won't be working under non
windows systems.
Always supply modeline to make sure basic editing things will be working
for others.
When changing options use setlocal not set - be polite to user
environment.
Try to cut on g:variables (see above).
Try to maintain documentation, not only for use of script but also for
messing with it.

Each script covers only part of Vim functionality. It is hard to say
which one is best for learning.

It depends on what are you want to achieve.

Avoid \| in complex regexps, often two, separate substite() are
faster than one substite() with \|.
Avoid * whenever possible, try to use \+ if appropriate.
\x class is faster than [collection]
When doing complex substitutions it is often faster to check if some
part of pattern already exists and only if this is true execute
substitution.
