[ #134 ] Manually Setting Vim Syntax Permalink
If you are editing a Perl script but the script name doesn't have a .pl extension and no hashbang line, your syntax highlighting will not work.
To manually set the syntax highlighting do this:
:set syntax=perl
[ #113 ] Merging Changes using VimDiff Permalink
Core Dump has a nice entry on this.
$ vimdiff file1 file2
Keyboard Shortcuts: do - Get changes from other window into the current window. dp - Put the changes from current window into the other window. ]c - Jump to the next change. [c - Jump to the previous change.
[ #110 ] Vim - What Changes Did I Make? Permalink
If you open a file in Vim, make some changes, then want to check those changes compared to when you opened it (do a diff before saving), then you have a few options:
:w !diff % -
... is an easy one. Others include:
[ #108 ] Perly Vim Permalink
Vim regexes aren't great, especially if you are used to Perl ones. When you are looking for a Perly way to substitute some text in Vim, try the simple:
:perldo s/something \d+/another/
This is a good way to make sure your ranges, special chars, character classes and flags etc work the way you have come to expect from using Perl.
By default this operation works on the entire file, but you can prefix the command with line ranges like you would with a normal Vim substitution.
[ #91 ] Case Insensitive Vim Search Permalink
There are a couple of options. If you want to do a once-off case-insensitive search, include the sequence \c in your search string anywhere, for example:
/SoMeThInG\c
... will match Something, something, someThing etc.
If you want case-insensitive searching to be the default, then add this to your .vimrc:
:set ic
If you are using set ic you might want to use the smart-case setting:
:set scs
... which, when the two settings are combined, will be mean that when you search for an all-lowercase word it will match any case, but if you have at least one uppercase character in the search string it will be case-sensitive. For example:
/mouse
... will match Mouse, MOUSE, mouse etc, but:
/Mouse
... will only match Mouse.
[ #89 ] .vimrc file Permalink
Here is my .vimrc file, for coding goodness!
set hidden
set nocompatible
set bs=2
set ts=4
set sw=4
syntax on
set softtabstop=4
set expandtab
set nohlsearch
set ruler
set ai
set backupdir=~/.backup
set directory=~/.backup
This config gives syntax highlighting and 4-space "tabs." It also puts all the swap files in the ~/.backup dir so they don't pollute your workspace. If you are having problems with the arrow-keys making weird codes (like "B" and "D") then using this config will fix that.
First remember to:
$ mkdir ~/.backup
