# eregex.vim
## Installation
It is recommended to install the script using [Vundle][] or [pathogen][].
[Vundle]:https://github.com/gmarik/vundle
[pathogen]:https://github.com/tpope/vim-pathogen
## Quick Start
After installation, just press / or ? as usual.
This will map to `:M/` command, which is used to perform the PCRE search.
You can call `eregex#toggle` funtion to toggle the keymapping. For example,
add the following line into your `.vimrc` file:
nnoremap / :call eregex#toggle()
Then you can use / to toggle the eregex.vim.
For replacement, use `:%S//` (uppercase S) to trigger perl style regexp.
See `:help eregex` for more information.
## Config
To disable the script by default, put this line in your `.vimrc` file:
let g:eregex_default_enable = 0
To change the search delimiter to something else than the default `/` and `?`,
following options can be used:
let g:eregex_forward_delim = '/'
let g:eregex_backward_delim = '?'
To force case sensitive like perl re. Add the following config:
let g:eregex_force_case = 1
Then you will have case sensitive match by default. You can always change it by adding `/i` modifier.
