Re: .vimrc for perl programmers

:imap dumper <ESC>^iwarn Data::Dumper->Dump([\<ESC>llyw$a], ['<ESC>pa']);<ESC>
lets you type '@myarraydumper' and you'll get 'warn Data::Dumper->Dump([\@myarray], ['myarray']);
map ß O#!/usr/local/bin/perl<CR><ESC>iuse strict;<CR><ESC>iuse warnings;<CR>
(un)comment: (update: this also works in visual mode. just select the block and type §1)

map §1 :s/^/# /<CR>
map §2 :s/^# //<CR>

Youll get more accurate results on self referential structures by using `warn Data::Dumper->Dump(sub{\@_}->(\@myarray), ['myarray'])` [download] it doesnt make that much difference when the example is an array, but when its a scalar it does make a lot of difference. Alternatively install Data::Dump::Streamer and get prettier, easier to read and more accurate dumps outright. Yes, this is a shameless plug. :-) --- $world=~s/war/peace/g	[reply] [d/l]

can you provide an example where this (undocumented?) syntax makes a difference?	[reply]

Looks like its been superficially improved so there is no difference anymore, which is good. But the output is still wrong, which is bad. For `$x=\$y; $y=\$x;` the raw call to `Data::Dumper->Dump([$x,$y])` used to produce: `$VAR1 = [ \\$VAR1->[0], ${$VAR1->[0]} ];` [download] But now it produces what Data::Dumper::Dumper (and what the sub{\@_} trick does) produce: `$VAR1 = \\$VAR1; $VAR2 = ${$VAR1};` [download] Wheras `Data::Dump::Streamer::Dump` produces the correct output: `$REF1 = \$REF2; $REF2 = \$REF1;` [download] Hope that explains things. --- $world=~s/war/peace/g	[reply] [d/l] [select]

For commenting and uncommenting code (in perl and many other languages) have a look at the BlockComment plugin.	[reply]
