DESCRIPTION

|
|
============
|

|
|
|
||
|
|
It's hard to find colorschemes for terminal Vim. Most colorschemes are
|
||
|
|
written to only support GVim, and don't work at all in terminal Vim.
|
||
|
|
|
||
|
|
This plugin makes GVim-only colorschemes Just Work in terminal Vim, as long
|
||
|
|
as the terminal supports 88 or 256 colors - and most do these days. This
|
||
|
|
usually requires no user interaction (but see the help for what to do if
|
||
|
|
things don't Just Work). After getting this plugin happily installed, any
|
||
|
|
time you use :colorscheme it will do its magic and make the colorscheme Just
|
||
|
|
Work.
|
||
|
|
|
||
|
|
Whenever you change colorschemes using the :colorscheme command this script
|
||
|
|
will be executed. It will take the colors that the scheme specified for use
|
||
|
|
in the GUI and use an approximation algorithm to try to gracefully degrade
|
||
|
|
them to the closest color available in your terminal. If you are running in
|
||
|
|
a GUI or if your terminal doesn't support 88 or 256 colors, no changes are
|
||
|
|
made. Also, no changes will be made if the colorscheme seems to have been
|
||
|
|
high color already.
|
||
|
|
|
||
|
|
If for some reason this transparent method isn't suitable to you (for instance
|
||
|
|
if your environment can't be configured to meet the |csapprox-requirements|,
|
||
|
|
or you need to work in Vim 6), another option is also available: using the
|
||
|
|
|:CSApproxSnapshot| command to create a new GUI/88-/256-color terminal
|
||
|
|
colorscheme. To use this command, a user would generally start GVim, choose a
|
||
|
|
colorscheme that sets up the desired colors, and then use |:CSApproxSnapshot|
|
||
|
|
to create a new colorscheme based on those colors that works in high color
|
||
|
|
terminals. This method is more flexible than the transparent mode and works
|
||
|
|
in more places, but also requires more user intervention, and makes it harder
|
||
|
|
to deal with colorschemes being updated and such.

|
Ideally, this plugin should require absolutely no configuration, but you may
|
||
|
|
need some tweaking to make sure vim realizes that your terminal supports more
|
||
|
|
than 16 colors. Also, konsole and Eterm users will want to make sure that
|
||
|
|
this plugin realizes that the terminal does not use colors that are exactly
|
||
|
|
xterm-compatible; they will want to skim through the help articles
|
||
|
|
|csapprox-palettes| and |csapprox-configuration| for a better end result.
