Perl Editor Voodoo

by vroom (Pope)
on Feb 19, 2002 at 14:55 UTC ( #146388=perlmeditation: print w/ replies, xml ) Need Help??

I've been attempting to beef up my .vimrc. The goal is as always to simplify my life somewhat. I'm curious what types of shortcuts, macros, and other magic people have in their vimrc's. If you *gasp* use another editor perhaps you can contribute other editor-specific tips for other users out there too. Here are some of the things I've added so far:
iab _cb ############################################################<C +R> iab _cl # #<C +R> iab _ds <C-R>=strftime("%Y-%b-%d")<CR> iab _fn <C-R>=bufname("%")<CR> iab _lm <C-R>="Last Modified: " . strftime("%a %b %d %H:%M:%S %Y") <C +R> iab _href <a href="" alt=""></a> iab _img <img src=""> iab <TABLE> <TABLE></TABLE> iab <TR> <TR></TR> iab <TD> <TD></TD>

    You might find info in this snippet, this script and this more descriptive node useful.

    My personal contribution is:
    :map \# ^[I#!/usr/bin/perl -w^Muse strict;^M
    update
    I have been using Vim with embedded Perl for a while.
    I don't think I am exploiting all the possibilities, but it is really helpful to have perl regular expressions at your disposal, so you don't have to think about the differences between the two RegEx dialects. Once you are used to Perl's syntax, capturing parentheses in Vim  \(.*\) look painfully unfamiliar.
    I often use Perl's sort to manipulate my lines of text.

    A nice feature is that you can test one or more lines of code, while you are writing them. Here is just one example:
    # line 10 of your code $a = sqrt(64);
    If you want to see the result of that assignment (provided that your internal CPU can't calculate it :) this command
    :10perldo s/$/$_/ee
    will append the result at the end of the line.
    I mapped this command, referring to the current line.
    :map _ee ^[:.,.perldo s/$/$_/ee^M
    I am sure that there is a lot more than these few tricks. Having Perl embedded in your editor can trigger your imagination!

    On a somewhat related note:
    Has anyone else compiled vim with the perl interface enabled? Last night I decided I wanted to bring my vim up to date and applied all the patches up to 6.0.225. Since I was doing that, I thought I'd compile in the perl support. Haven't had much time to play with it yet, but it looks promising.

      And as a compiler-ignorant Win32 user... does anyone have a pre-compiled binary of Vim with Perl support, or can someone point me in the right direction? (using Perl 5.6.1)

      Cheerio!

    one particular shortcut i use all the time is when i need to comment out certain lines (which are not contiguous)
    map @ I# ^[j
    This makes it possible to add the # sign at the beginning of the line,regardless of where the cursor is on the line) using the @ sign
    Since I need to write database-related code, these shortcuts also come in handy
    ab sd $sth = $dbh->prepare($sql); ab se $sth->execute ab sa $sth->fetchrow_hashref; ab ss $sth->finish;

    I have so much in my vimrc that I sometimes forget what nice features I have :)

    In the skel.pl file you can put -w and strict

    The shortest and handiest line in my .vimrc is:
    map <return> i

    apart from that I like
    map <anykey> :!make<return> imap <anykey> <esc>:!make<return>i
