Context Colour

[karimlevallois]

Just trying to change the context highlight colour (Treesitter) from white to blue. Tried adding 'char_highlight' under my config, but that doesn't seem to be working.

Any help greatly received.

Ah, fixed it with vim.cmd[[highlight IndentBlanklineContextChar guifg=#F8BD96 gui=nocombine]]

[karimlevallois]

OK, so Python files seem to be highlighting correctly. Grey indentations being shown and peach while in context. However, HTML aren't being highlighted while in context, just grey indentations showing?

[lukas-reineke]

If you don't have context for HTML, it probably means your context_patterns are missing the patterns for HTML. You can check how they look like with ::TSPlaygroundToggle

[karimlevallois]

Fixed it by just removing my context_patterns list.

Sorry for adding on a closed issue, I wanna modify the colour as well but the command doesn't change anything somehow 😕

local M = {}

function M.setup()
    local status_ok, indent_blankline = pcall(require, "indent_blankline")
    if not status_ok then
        return
    end

    indent_blankline.setup {
        show_trailing_blankline_indent = false,
        space_char_blankline = " ",
        use_treesitter = true,
        show_current_context = true,
        show_current_context_start = true,
    }

    vim.cmd[[highlight IndentBlanklineContextChar guifg=#62646C gui=nocombine]]
end

return M

Any clues? Cheers~

[lukas-reineke]

Your code looks correct. Maybe the highlight group gets overwritten somewhere? You can check if and where it was set with :verbose highlight IndentBlanklineContextChar

[Soooda]

Thank you very much! Indeed, it looks like I config the new context indent colour before setting my color scheme so it got overwritten. Resolved!
