Terminal "only" has 16777216 colors
After recently updating macOS (v10.15.6), Alacritty (v0.5.0) and Vim (v8.2.1456), CSApprox starts emitting a warning about having not enough terminal colours even though I actually have quite a lot:
CSApprox skipped; terminal only has 16777216 colors, not 88/256
So I have too many colours to use csapprox? :)
What's the output you get from:
:verb set term? t_Co? t_AB? t_AF? t_Sb? t_Sf?
And, for that matter, the full output from:
:set termcap
In the terminal outside of vim, does tput colors also print 16777216?
What color does "hello" print in if you run this in a terminal?
tput setaf 16776960; echo hello; tput sgr 0
And can you paste what this gives you?
infocmp
Thanks for your response, and sorry that it's taken me so long to respond to your response! The output of :verb set term? t_Co? t_AB? t_AF? t_Sb? t_Sf? is:
term=builtin_gui
t_Co=16777216
t_AB=
t_AF=
t_Sb=
t_Sf=
and :set termcap gives:
t_AB= t_EI= t_RS= t_ts=
t_AF= t_fs= t_RT= t_u7=
t_AU= t_GP= t_RV= t_ue=^[|8H
t_AL=^[|%p1%dI t_IE= t_Sb= t_us=^[|8h
t_al=^[|i t_IS= t_SC= t_ut=y

Outside of vim, tput colors gives 256; the $TERM environment variable is screen-256color.
Running tput setaf 16776960; echo hello; tput sgr 0 gives a regular white/grey hello.
Finally, infocmp outputs:

I have this exact issue with the exact error message; 16777... on arch linux using the latest Gvim (does not happen in vim in the terminal)
In terminal:
>>> tput colors
256
>>> tput setaf 16776960; echo hello; tput sgr 0
hello

Open the .vim file of GSApprox, e.g. /usr/share/vim/vimfiles/plugin/CSApprox.vim
Find
" Return if not running in an 88/256 color terminal
if &t_Co != 256 && &t_Co != 88
if &verbose && &t_Co != ''
echomsg "CSApprox skipped; terminal only has" &t_Co "colors, not 88/256"
echomsg "Try checking :help csapprox-terminal for workarounds"
endif
return
endif
Change the inner 'if' to your liking. For me, up to the upgrade to vim/gvim 8.2.3741, t_Co was empty, so the message was not printed because of this, not because it should not be printed. As you see in the inner 'if', the message is printed if verbose mode is on and t_Co is not empty. So, if your t_Co now (after a vim/gvim upgrade) has (finally) the correct value of 16777216, instead of being empty, then the message is correct.
You may of course find it annoying and change the inner 'if' to
if &verbose && &t_Co != '16777216'
echomsg "CSApprox skipped; terminal has" &t_Co "colors, not 88/256"
echomsg "Try checking :help csapprox-terminal for workarounds"
endif
or whatever other combination of conditions you like. I have changed mine to
if &verbose && &t_Co != '' && &t_Co != '16777216'
echomsg "CSApprox skipped; terminal has" &t_Co "colors, not 88/256"
echomsg "Try checking :help csapprox-terminal for workarounds"
endif
Of course, CSApprox is still NOT loaded (and correctly so) - only the message is suppressed, even in verbose mode.
