This Vim plugin disapproves deeply indented code.
By default, it shows ಠ_ಠ at the beginning of each line that is indented at least 5 levels.
It can be configured with the following variables (setting them to 0 disables the feature):
let g:LookOfDisapprovalTabThreshold=5
let g:LookOfDisapprovalSpaceThreshold=(&tabstop*5)
You can easily install this Plugin with Pathogen or Vundle.
Vim needs to be compiled with +conceal for the face to appear.
The idea came from a comment made by StripTheFlesh in this thread on Reddit:
Just use ಠ_ಠ for indents. It will remind you to not use a lot indentation levels.
The plugin uses Vim's conceal feature. It does not modify the source code in any way, the disapproving look is just a visual indicator.
Conceal depends on modifying the syntax highlighting rules. For some file types and syntax settings, the rules defined in this plugin may conflict with the default rules applied for a filetype, making the look of disapproval appear in the beginning of shallowly indented lines as well.
In the case you encounter this issue, feel free to open an issue. Until it's fixed, you can disable the plugin for the problematic file types with the following command:
autocmd FileType SOME_FILETYPE let g:LookOfDisapprovalTabThreshold=0 | let g:LookOfDisapprovalSpaceThreshold=0
