This file is sourced before any other file or plugin. Janus core is loaded before this script, so you get access to all the functions defined in janus.vim.
This is perfect for setting things like the
any mappings using the
<leader> keywords that is parsed before
mapleader won't have any effect on them.
~/.vimrc.after is loaded after Janus but before other plugins
are loaded. This allows you to override anything set by Janus or
This is useful for re-mapping some of the bindings to your
liking, setting the colorscheme, changing the
encoding or the
~/.janus directory for your custom additions. These
will be loaded before any other group, except of course the core
group. This will ensure that your version of any already-installed
plugins will be loaded instead.
To add customizations or add more Vim plugins, create a
directory and add your plugins there, either with a
git clone or by
adding submodules to your own git repository there. This directory is
treated like a normal pathogen directory. An example of adding a plugin:
$ cd ~/.janus $ git clone https://github.com/vim-scripts/Rename2.git rename2
Or, if you have a git repository in
~/.janus, you can use a submodule:
$ cd ~/.janus $ git submodule add https://github.com/vim-scripts/Rename2.git rename2
Note: Plugins must be added within a containing directory as would be
done by the git commands above, and not the bare
(as would be done in with Vim in
~/.janus folder separate from the janus checkout in
lets you manage this folder of your own customizations separately,
making it easier to duplicate your setup on multiple machines.
To override a color theme bundled with janus or plugin that cannot be
loaded twice, you can place your plugin in
$ cd ~/.janus.before $ git clone https://github.com/jnurmine/Zenburn.git
Even if not every vim-script hosted on
vim.org has a git repository
(by the author or a mirror), you can easily cro a git repository for it
using Vim-scripts Github mirror.
The list of color schemes can be found in the
Janus makes it easy to disable any included plugin, color-scheme,
lang etc. Disabling a plug-in is done only within your
file using the janus#disable_plugin() method. This does not work
~/.gvimrc.before. This methods takes two arguments: the plugin
name and optionally the reason for disabling the plugin. If
reason is given, all bindings that Janus binds to the plugin
will still be bind but the action will just be an echo that the plugin
is disabled. For example:
Janus adds the binding
<D-t> on MacVim to open the
plugin which requires Vim built with
ruby support. If your Vim is not
ruby support, your Vim will not throw errors about it
because Janus will disable the plugin automatically. However, if you
<D-t> (you might expect that nothing happens but..) the
following message appears in the command-line area:
The plugin command-t is disabled for the following reason: Vim is compiled without ruby support.
Here's the signature of the
janus#disable_plugin function. You might
notice in the source code that it supports specifying the group as well,
but since this feature is not working yet, please ignore it.
" Disable a plugin " " @param [String] The plugin name " @param [String] The reason why it is disabled " @return [Bool] function! janus#disable_plugin(...) endfunction
Disabling a plugin in
" Disable command-t because I don't like it, but keep the bindings to remind me call janus#disable_plugin('command-t', "I don't like it") " Disable Hammer because it doesn't work and remove the bindings call janus#disable_plugin('hammer')
The snippets that come with Janus are very extensive, but part of the allure of vim is being able to customize your setup. Adding snippets to Janus is really simple.
If you haven't already setup a
~/.janus directory, go ahead and do so.
snipMate will hunt for a snippets directory in the sub directories of
~/.janus (but not at the root level). So, make a directory
mkdir -p ~/.janus/mysnippets/snippets # mysnippets can be whatever you like
Then place a blank
_.snippets file in that directory to signal that
it's a directory with snippets in it:
You can now create snippets in your new snippets directory (~/.janus/mysnippets/snippets) following the regular snipMate help file instructions.
Creating Snippets That Already Exist In Janus
You'll likely run into creating a snippet that already exists in Janus's core snippets. If this happens, Vim will simply prompt you and ask which snippet you want to use.
If you run into this often, you may find it annoying and prefer to
exclude all of Janus' snippets. This is easily done by using the
disable plugin function in your
Of course, you could continue even further by following the steps above and create another custom snippets directory, but instead clone the honza repo in it and manually edit those snippets. It's Vim...it's up to you!
