IndentWise

Description

IndentWise is a Vim plugin that provides for motions based on indent depths or levels in normal, visual, and operator-pending modes.

Movements by Relative Indent-Depth

The following key-mappings provide motions to go to lines of lesser, equal, or greater indent than the line that the cursor is currently on:

  • [- : Move to previous line of lesser indent than the current line.
  • [+ : Move to previous line of greater indent than the current line.
  • [= : Move to previous line of same indent as the current line that is separated from the current line by lines of different indents.
  • ]- : Move to next line of lesser indent than the current line.
  • ]+ : Move to next line of greater indent than the current line.
  • ]= : Move to next line of same indent as the current line that is separated from the current line by lines of different indents.

The above all take a {count}, so that, e.g., 4[- will move to the previous line that is 4 indent-depths less than the current one. An "indent-depth" is simply the indentation of the line, and thus any line with a smaller amount of indentation relative to current line is considered at a lesser indent depth, and, conversely, any line with a greater indentation than the current line is considered to be at a greater indent-depth.

Movements by Absolute Indent-Levels

In addition, you can navigate directly to a line of a particular indent-level, with the level specified by a (mandatory) {count} directive, using:

  • {count}[_ : Move to previous line with indent-level of {count}.
  • {count}]_ : Move to next line with indent-level of {count}.

An "indent-level" of a line is the number of shiftwidth units that the line is indented (as opposed to the "indent-depth", which is just the indentation amount of a line).

Movements by Indent-Block Scope

The following key-mappings provide motions based on indent-block scope boundaries, with an optional {count} directive specifying the number of levels of scope to include:

  • [% : Move to beginning of indent-block scope (i.e., move to the line just after the previous line of lesser indent); repeat for {count} outer scopes.
  • ]% : Move to end of indent-block scope (i.e., move to the line just before the next line of lesser indent); repeat for {count} outer scopes.

Customization

If you are unhappy with the default key-mappings you can provide your own by defining custom mappings in your .vimrc. For example to replicate the default mappings, you would define the following:

map [- <Plug>(IndentWisePreviousLesserIndent)
map [= <Plug>(IndentWisePreviousEqualIndent)
map [+ <Plug>(IndentWisePreviousGreaterIndent)
map ]- <Plug>(IndentWiseNextLesserIndent)
map ]= <Plug>(IndentWiseNextEqualIndent)
map ]+ <Plug>(IndentWiseNextGreaterIndent)
map [_ <Plug>(IndentWisePreviousAbsoluteIndent)
map ]_ <Plug>(IndentWiseNextAbsoluteIndent)
map [% <Plug>(IndentWiseBlockScopeBoundaryBegin)
map ]% <Plug>(IndentWiseBlockScopeBoundaryEnd)
