# 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. ## Changes ### 2.61 * Support for ignorecase ### 2.60 * Support for the backword search. * Support for the count argument. * Use function to auto map keys. * Support for custom search delimeters. * hlsearch works fine. ## License Author : 安久津 Origin : [eregex.vim][origin] Maintainer : othree See `:help eregex-license-to-use` for license information.
