[CATPPUCCIN] color theme for [NEOVIM] is unsupported in ROXTerm version 2.9.5 about roxterm HOT 7 CLOSED

I also noticed you're not using roxterm's overlay scrollbars option (available in the Scrolling section of the profile). It looks better and saves space, especially when the scrollbar is redundant while using vim.

from roxterm.

Overlay scrollbars can be enabled by adding overlay_scrollbar=1 to your profile file, or in the GUI (Preferences > Edit Current Profile):

If that option is missing, you probably have an obsolete version of roxterm, which hopefully also explains the problem with catppuccin. I've installed the nvim theme myself and it works correctly in roxterm for me. Maybe full color isn't enabled in your version of roxterm? If it is, the COLORTERM environment variable should be set to truecolor by vte.

The latest version of roxterm is 3.14.3. You can get it from my PPA for Debian-based systems, or from roxterm-git in AUR for Arch-based systems.

It might be because of the TERM value of "gnome-256color". The default is xterm-256color. Try deleting the TERM part of the command option in your profile, and the two lines after that (I think the color_term key is a relic from an old version, because there's currently no reference to it in the source code). If that doesn't fix it, please could you test with another vte-based terminal, for example gnome-terminal, and see if it has the same problem?

from roxterm.

The reason why I modified TERM value to gnome-256color from xterm-256color is because it causes some problems with nvim characters, as shown in the picture below. Changing it back to xterm-256color however didn't solve the theme color problem

the below config didn't work either

Proceeding to test with gnome-terminal.

How do I do that? Which value should be changed?

To my surprise it works on gnome-terminal as well.

You're right I'm using roxterm version 2.9.5 GTK 2/VTE 9 build as I mentioned earlier, because apparently that's the latest version available via apt (I'm using a debian based OS).

I have tried changing the value of COLORTERM to truecolor and yet it didn't work. Also, the overlay_scrollbar variable is missing. So, it's safe to conclude roxterm version 2.9.5 GTK 2/VTE 9 build doesn't support Catppuccin colorscheme for Neovim.
Installing roxterm version 3.14.3 from Roxterm PPA and closing this issue.
