Dotvim2

What?

This is the second incarnation of my dotvim configuration

V1 can be found here

IMPORTANT: Please be sure to read the installation section!

Why

Over the years V1 became too bloated, and hard to update and fix. Once something went-in, its hard to remove it, since somebody might be using it.

Also, people kept sending me patches with their favorite plugins, which might not necessarily be useful for everybody.

The result is that the configuration became way too big and slow.

So my goals for this v2 release are:

  • easy customization and extensibility. It should be easy to add optional functionality, plugins, bindings etc. with dotvim v1 its easy to make any plugin conditionally loadable, any value to be configurable (and have a default), etc.

  • upgradeability. Your customizations should easily survive version upgrades. If you decided that you don't need 'ruby support', you should still have it 'off' next time you upgrade the version. But it should be trivial to bring it back if you ever need to.

  • minimal boilerplate. You can always achieve configurability by defining a ton of vim variables and checking them with 'ifs' all over the place. This is ugly and not productive. Dotvim2 uses a shell library to keep, update, and merge your "choices" in a shell script file .config. More info TBD.

Status

dotvim2 seems to be stable enough at this point, I'll probably release 1.0 soon.

Note that not all plugins from v1 made it into v2, if you are missing anything major, please let me know ;)

Major changes

Modularity

The number 1 major feature is that its all very modular now. Many parts are optional, and its actually trivial to make most any other part optional too.

The modularity is achieved by switching from configuration files to configuration file templates and generators. You no longer use the project as-is, instead you run make in it, to generate your actual configuration in your directory of choice. You can (and its recommended to) keep this generated directory content in git as well, so that after every upgrade or configuration change you can see the exact difference.

Note: while the idea is to have this very customizable, there are still many parts and plugins that are hard-coded. Those are mostly those plugins and settings that I consider to be essential, ans so I didn't bother (yet) to allow for customization. That being said, its very easy to make any part of setup configurable. Just look at any prompt.sh file inside plugins directory. Oh, and pull requests are welcome ;).

dein

NeoBundle was replaced with dein. This time around it seems that this time around vim plugin managers are ten a penny. So I just went with dein, which is the replacement from the author of NeoBundle. NeoBundle was fast, Dein supposed to be faster still.

TBD

## Installation

Clone this repository and run make.

Installation will ask you a ton of questions and then generate your vim configuration in the VIM_DIR directory. The default is ./dist, but you can pass it anything through environment or arguments. e.g.:

VIM_DIR=~/.vim make

if you use a directory other then ~/.vim you will need to link it so that vim can find it, e.g.:

ln -sfn YOUR_VIMDIR_PATH ~/.vim

Note: Depending on your version of vim you might also have to link ~/.vimrc => YOUR_VIMDIR_PATH/vimrc. Newer versions can use ~/.vim/vimrc, but older versions will only look for ~/.vimrc

Once your configuration is generated and linked you can run vim, it will detect missing plugins and install them on the first run.

Configuration

Your configuration choices are stored in VIM_DIR/.config. You can edit it directly or just run make edit.

You will be asked quesions during the install only if the config file doesn't already contain the answer.

make reconfigure will ask all questions all over again, with your previous choices used as defaults.

During the installation a README file is generated in the destination directory with just the information relevant to your own configuration chocies.

The README file in the project repository was generated with my own configuration ;).

YouCompleteMe

Dotvim2 (optionally) uses YouCompleteMe for code completion (v1 used AutoComplPop).

It is a quite a bit more complex and not without its problems, but it seems to be the completion plugin to use at this time.

Note: You will need cmake installed if you want this to work.

IMPORTANT: YouCompleteMe installation seems to be quite problematic. One particular problem that happened to me a lot is git failing to featch all the submodules from github. In case of such a failure you can try to run make completion, which will retry YouCompleteMe installation. you might need to run it seveal time until it succeeds.

TBD

load order

  • vimrc
    • vimrc.plugins
      • ~/.vimrc.plugins
      • gvimrc.plugins
        • ~/.gvimrc.plugins
    • << here all plugins are actually loaded >>
    • after/plugin/after.vim
      • vimrc.after
        • ~/.vimrc.after
        • gvimrc.after
          • ~/.gvimrc.after

Each plugin can add content to files in the target vim directory by simply having the corresponding files present in the plugin/files directory

E.g. if plugin foo has file plugins/files/directory/files, then this file's content will be added to ~/.vim/directory/files

Plugins found in the plugins subdirectory will be automatically loaded as well.

To make sure each such files will be re-created appropriately upon each install run, they have to be cleaned up.. 10-init/plugins/10-cleanup plugin takes care of the standard ones, if you need a new one, you might need to clean it up your self. place it in 000=-.... plugin directory to make sure it is called before any other plugin tries to add content to it.

If a plugin has a prompt.sh file in the directory, its loading will be conditioned on evaling this script.

If the script "fails" (i.e. non-zero exit code), then the plugin will not be loaded.

IMPORTANT: The prompt script is evaled in the contenxt of the generator, so it has access to all the state and functions, so it can run ask... functions, etc.

Note that prompt.sh should usually only ask simple question and return true/false, if you want something more complex create an install.sh instead.

If a plugin has an install.sh file in the directory, it will be sourced.

so the logic flow is as follows:

  • check for prompt.sh and exit if it returns false
  • copy files from files directory
  • load all plugins in the plugins directory
  • run install.sh if exists

TBD.
