Can't enable 256 colors in ConEmu

Question

I'm trying to get 256 colors in the fantastic ConEmu-Maximus5 console.

Update: Now it only shows 8 colors. I know because '$tput colors' output is '8'

I have followed the instructions and activated:

• TrueMod (24-bit color) support
• Inject ConEmuHk
• ANSI x3.64 / xterm 256 colors

I don't understand what to do with 'check off whether the buffer / slide.'

• I'm in windows 7.
• I start ConEmu with a custom direct link, so it loads cygwin bash file.

 "C:\Program Files\ConEmu\ConEmu64.exe" /cmd ""C:\cygwin\bin\bash.exe" --login -i" 

• In my bashrc profile I have -> export TERM=cygwin
• This is my custom command prompt:

     function prompt {      local RED="\[\033[0;31m\]"     local GREEN="\[\033[0;32m\]"     local COOLRED="\e[38;5;173m"     local COOLGREEN="\e[38;5;113m"     PS1="$COOLRED\u@\h $LIGHT_COOLGREEN\$PWD \[\e[0m\] > "      }      prompt 

• The value of ConEmuANSI in ON, by the way.

I have some screen shots:

As you can see the command prompt looks very extravagant because it doesn't like the 256 color settings. If i substitute the variables COOLRED and COOLGREEN with RED and GREEN, then it looks ok, but it's not 256 colors.

More screenshots of the settings:

And the last sceen shot it's cygwin's mintty. Everything is ok there. Full 256 color supported. It's a shame mintty doesn't have tabs. That's mostly the reason why I'm trying to move to ConEmu.

Thank you very much for helping!!!

Answer 1

Bash does not send ANSI sequences to console. It tries to process them itself. And, because *nix terminal is generally only 8-color (not taking into account 256-color mode), bash uses 8-color palette instead of 16-color palette which is common to Windows terminal.

I think, 256-colors works in mintty because _isatty returns zero in that terminal. But it returns non zero value under ConEmu. May be in future builds I solve this puzzle (how to create real terminal with PTY features for some applications).

As for the question

You have no need in 256-colors In fact. To redefine prompt palette you may use "Extend foreground colors with background" feature. In breaf - set up colors 16, 17, etc. in ConEmu, set prompt background in bash to #5 (configurable in ConEmu), and voila.

There was a small bug in ConEmu "Extend..." processing. Use build 121016 or later.

PS1="\e[30;45m\u@\h \e[34;45m$PWD \[\e[0m\] > " 

Following info does not match the question, but may be useful

Current version does not support 256-color mode in 'whole' console buffer (limitation, yes, removing it in plans).

So, you can go 2 ways

• totally disable scrollback buffer (many ways, for example "cmd -cur_console:h0")
• work in the bottom of the scroll-buffer.

Answer 2

I also couldn't get 256 color support to work (the colors would show up, but they looked the same as the 16-color palette). I switched to the "xterm" color scheme and now it works in native Windows executables (such as Python) but not in anything that uses Cygwin. Cygwin appears to have terminal-escape-sequence processing that you can't turn off, which defeats the ConEmuHk injection.

This is documented on the ConEmu wiki, here.
