This is a list of the frequently asked questions about SpaceVim. Including questions about installation, configuration and usage.


Where is my old vim configuration?

In Linux/MacOS, the old vim configuration file ~/.vimrc will be renamed to ~/.vimrc_back, and the directory ~/.vim also will be renamed to ~/.vim_back.


Can I try SpaceVim without overwriting my vimrc?

The SpaceVim install script will move your ~/.vimrc to ~/.vimrc_back. If you want to have a try SpaceVim without overwriting your own Vim configuration you can:

Clone SpaceVim manually.

git clone ~/.SpaceVim

Then, start Vim via vim -u ~/.SpaceVim/vimrc. You can also put this alias into your bashrc.

alias svim='vim -u ~/.SpaceVim/vimrc'

Why use toml as the default configuration file format?

In the old version of SpaceVim, we used a Vim file (init.vim) for configuration. This introduced a lot of problems. When loading a Vim file the file content is executed line by line. This means that when there was an error the content before the error was still executed. This led to unforeseen problems.

We decided going forward to use a more robust configuration mechanism in SpaceVim. SpaceVim must be able to load the whole configuration file and if there are syntax errors in the configuration file, the entire configuration needs to be discarded.

We compared TOML, YAML, XML, and JSON. We chose TOML as the default configuration language. Here are some of the drawbacks we found with the other choices considered:

  1. YAML: It is error-prone due to indentation being significant and when configuring transitions.
  2. XML: Vim lacks a parsing library for XML and XML is hard for humans to write.
  3. JSON: Is a good configuration format and Vim has a parsing function. However, JSON does not support comments.

Where should I put my configuration?

SpaceVim loads custom global configuration from ~/.SpaceVim.d/init.toml. It also supports project specific configuration. That means it will load .SpaceVim.d/init.toml from the root of your project.

E492: Not an editor command: ^M

The problem was git auto added ^M when cloning, solved by:

git config --global core.autocrlf input

Why SpaceVim can not display default colorscheme?

By default, SpaceVim uses true colors, so you should make sure your terminal supports true colors. This is an article about what true colors are and which terminals support true colors.

Why can’t I update plugins?

Sometimes you will see Updating failed, The plugin dir is dirty. Since the plugin dir is a git repo, if the directory is dirty (has changes that haven’t been committed to git) you can not use git pull to update plugin. To fix this issue, just move your cursor to the error line, and press gf, then run git reset --hard HEAD or git checkout .. For more info please read git documentation.

How to reload init.toml?

You can not reload init.toml after startup. After editing the init.toml file, you need to restart your vim or neovim.

How to enable +py and +py3 in Neovim?

In Neovim we can use g:python_host_prog and g:python3_host_prog to config python prog. In SpaceVim the custom configuration file is loaded after SpaceVim core code. So in SpaceVim itself, if we using :py command, it may cause errors. So we introduce two new environment variables: PYTHON_HOST_PROG and PYTHON3_HOST_PROG.

For example:

export PYTHON_HOST_PROG='/home/q/envs/neovim2/bin/python'
export PYTHON3_HOST_PROG='/home/q/envs/neovim3/bin/python'

Why does Vim freeze after pressing Ctrl-s?

This is a feature of terminal emulators. You can use Ctrl-q to unfreeze Vim. To disable this feature you need the following in either ~/.bash_profile or ~/.bashrc:

stty -ixon
