Vim mappings made within a file

Question

When you do a key mapping from within Vim and a certain file, does that mapping get saved for that file (Meaning that when I reopen that file at a later time, the mapping will still hold, but not for other files)?

I have done the remapping in my vimrc before but not like this, so I am unsure.

Thanks

Answer 1

Filetype specific mappings goes to plugin/ftplugins/<filetype>.vim . You can keep your mapping there, for instance, plugin/ftplugn/cpp.vim .

For you can make a autocmd for whatever mapping you want

autocmd FileType cpp map <buffer> <key> ...

You can put the filetype-related configuration into ~/.vim/ftplugin/<filetype>/<any-name>.vim . When you open file or create new file, Vim load all of files named ftplugin/<filetype>.vim and ftplugin/<filetype>/*.vim . I suggest to use ~/.vim/ftplugin/<filetype>/*.vim since you can separate files for each categories. For example,

• ~/.vim/ftplugin/html/pluginA.vim
• ~/.vim/ftplugin/html/pluginB.vim

You can separate configuration file for plugins.
