Localvimrc

This plugin searches for local vimrc files in the file system tree of the currently opened file. It searches for all ".lvimrc" files from the directory of the file up to the root directory. By default those files are loaded in order from the root directory to the directory of the file. The filename and amount of loaded files are customizable through global variables.

For security reasons it the plugin asks for confirmation before loading a local vimrc file and loads it using |:sandbox| command. The plugin asks once per session and local vimrc before loading it, if the file didn't change since previous loading.

It is possible to define a whitelist and a blacklist of local vimrc files that are loaded or ignored unconditionally.

The plugin can be found on Bitbucket, GitHub and VIM online.

Commands

The LocalVimRC command

Resource all local vimrc files for the current buffer.

The LocalVimRCClear command

Clear all stored decisions made in the past, when the plugin asked about sourcing a local vimrc file.

Variables

The plugin provides several convenience variables to make it easier to set up path dependent setting like for example makeprg. These variables are only available inside your local vimrc file because they are only unambiguous there.

Adding the following lines to a local vimrc in the root directory of a project modify the behavior of |:make| to change into a build directory and call make there:

let &l:makeprg="cd ".g:localvimrc_script_dir_unresolved."/build && make"

NOTE:

This is only possible if you disable sandbox mode.

Other variables provide a way to prevent multiple execution of commands. They can be used to implement guards:

" do stuff you want to do on every buffer enter event

" guard to end loading if it has been loaded for the currently edited file
if g:localvimrc_sourced_once_for_file
  finish
endif

" do stuff you want to do only once for a edited file

" guard to end loading if it has been loaded for the running vim instance
if g:localvimrc_sourced_once
  finish
endif

" do stuff you want to do only once for a running vim instance

The g:localvimrc_file variable

Fully qualified file name of file that triggered loading the local vimrc file.

The g:localvimrc_file_dir variable

Fully qualified directory of file that triggered loading the local vimrc file.

The g:localvimrc_script variable

Fully qualified and resolved file name of the currently loaded local vimrc file.

The g:localvimrc_script_dir variable

Fully qualified and resolved directory of the currently loaded local vimrc file.

The g:localvimrc_script_unresolved variable

Fully qualified but unresolved file name of the currently loaded local vimrc file.

The g:localvimrc_script_dir_unresolved variable

Fully qualified but unresolved directory of the currently loaded local vimrc file.

The g:localvimrc_sourced_once variable

Set to 1 if the currently loaded local vimrc file had already been loaded in this session. Set to 0 otherwise.

The g:localvimrc_sourced_once_for_file setting

Set to 1 if the currently loaded local vimrc file had already been loaded in this session for the currently edited file. Set to 0 otherwise.

Settings

To change settings from their default add similar line to your global |vimrc| file.

let g:option_name=option_value

The g:localvimrc_name setting

List of filenames of local vimrc files. The given name can include a directory name such as ".config/localvimrc".

Previous versions of localvimrc only supported a single file as string. This is still supported for backward compatibility.

  • Default: [ ".lvimrc" ]

The g:localvimrc_event setting

List of autocommand events that trigger local vimrc file loading.

  • Default: [ "BufWinEnter" ]

NOTE:

BufWinEnter is the default to enable lines like

setlocal colorcolumn=+1

in the local vimrc file. Settings "local to window" need to be set for every time a buffer is displayed in a window.

The g:localvimrc_reverse setting

Reverse behavior of loading local vimrc files.

  • Value 0: Load files in order from root directory to directory of the file.
  • Value 1: Load files in order from directory of the file to root directory.
  • Default: 0

The g:localvimrc_count setting

On the way from root, the last localvimrc_count files are sourced.

  • Default: -1 (all)

The g:localvimrc_sandbox setting

Source the found local vimrc files in a sandbox for security reasons.

  • Value 0: Don't load vimrc file in a sandbox.
  • Value 1: Load vimrc file in a sandbox.
  • Default: 1

The g:localvimrc_ask setting

Ask before sourcing any local vimrc file. In a vim session the question is only asked once as long as the local vimrc file has not been changed.

  • Value 0: Don't ask before loading a vimrc file.
  • Value 1: Ask before loading a vimrc file.
  • Default: 1

The g:localvimrc_persistent setting

Make the decisions given when asked before sourcing local vimrc files persistent over multiple vim runs and instances. The decisions are written to the file defined by and |g:localvimrc_persistence_file|.

  • Value 0: Don't store and restore any decisions.
  • Value 1: Store and restore decisions only if the answer was given in upper case (Y/N/A).
  • Value 2: Store and restore all decisions.
  • Default: 0

The g:localvimrc_persistence_file setting

Filename used for storing persistent decisions made when asked before sourcing local vimrc files.

  • Default (Unix): "$HOME/.localvimrc_persistent"
  • Default (Windows): "$HOME/_localvimrc_persistent"

The g:localvimrc_whitelist setting

If a local vimrc file matches the regular expression given by |g:localvimrc_whitelist| this file is loaded unconditionally.

Files matching |g:localvimrc_whitelist| are sourced even if they are matched by |g:localvimrc_blacklist|.

See |regular-expression| for patterns that are accepted.

Example:

" whitelist all local vimrc files in users project foo and bar
let g:localvimrc_whitelist='/home/user/projects/\(foo\|bar\)/.*'

" whitelist can also use lists of patterns
let g:localvimrc_whitelist=['/home/user/project1/', '/opt/project2/', '/usr/local/projects/vim-[^/]*/']
  • Default: No whitelist

The g:localvimrc_blacklist setting

If a local vimrc file matches the regular expression given by |g:localvimrc_blacklist| this file is skipped unconditionally.

Files matching |g:localvimrc_whitelist| are sourced even if they are matched by |g:localvimrc_blacklist|.

See |regular-expression| for patterns that are accepted.

Example:

" blacklist all local vimrc files in shared project directory
let g:localvimrc_blacklist='/share/projects/.*'

" blacklist can also use lists of patterns
let g:localvimrc_blacklist=['/share/projects/.*', '/usr/share/other-projects/.*']
  • Default: No blacklist

The g:localvimrc_autocmd setting

Emit autocommands |LocalVimRCPre| before and |LocalVimRCPost| after sourcing every local vimrc file.

  • Default: 1

The g:localvimrc_disable_upward_search setting

The plugin searches for g:localvimrc_name file from the directory of the current file up to the root directory. Set this option to 1 to disable upward search. If set to 1 plugin searches only in the file directory.

  • Default: 0

The g:localvimrc_debug setting

Debug level for this script.

  • Default: 0

Autocommands

If enabled localvimrc emits autocommands before and after sourcing an local vimrc file.

The LocalVimRCPre autocommand

This autocommand is emitted right before sourcing each local vimrc file.

The LocalVimRCPost autocommand

This autocommands is emitted right after sourcing each local vimrc file.
