Please help style headlines in markdown

[prankousky]

Hi everybody,

I just stumbled upon this plugin; since I use markdown a bunch, I wanted to integrate it in my workflow.

This is the ~/.config/nvim/plugin/headlines.vim file I started with:

lua << EOF

vim.cmd [[highlight Headline1 guibg=#F0F]]
vim.cmd [[highlight Headline2 guibg=#F0F]]
vim.cmd [[highlight CodeBlock guibg=#F0F]]
vim.cmd [[highlight Dash guibg=#F0F gui=bold]]

require("headlines").setup {
    markdown = {
        headline_highlights = { "Headline1", "Headline2" },
    },
}
EOF

I used #F0F so that any changes would be clearly visible. But it seems like these lines don't make any difference, whether they are there, or not, or commented out.

I changed that file to the bare minimum as well

lua << EOF
require('headlines').setup()
EOF

What do I need to change in order to make it look like in the example image? Screenshot

I also tried the default config, but it did not work. When I use this, I got some errors; I realized they could be solved by :TSInstall org, :TSInstall norg. I tried added the color modifying block again (see below image). However, after doing this, it looked like this

This is the file I used for the screenshot above

lua << EOF

vim.cmd [[highlight Headline1 guibg=#F0F]]
vim.cmd [[highlight Headline2 guibg=#F0F]]
vim.cmd [[highlight CodeBlock guibg=#F0F]]
vim.cmd [[highlight Dash guibg=#F0F gui=bold]]

require("headlines").setup {

I like the way the colors are in the example image. Also, I am planning to use this exclusively for markdown (no org, no norg, nothing else); could you please tell me how a minimal configuration would have to look in order to make markdown files look like in the example? This way, I could build on top of it in case I want to change the look.

Thank you in advance for your help :)

#F0F is not a valid hex color in Neovim. You have to type it out, #FF00FF should work.

When I use this, I got some errors; [...] Also, I am planning to use this exclusively for markdown (no org, no norg, nothing else);

Just don't include the default values in your config, then you won't get any errors.

Thank you. Using valid hex color works, and I got familiar with the syntax. I stripped the code down to what's below. I also tried to read the different :h headlines* files and believe the answer is "no", but I'll ask anyway: is it possible to get an icon similar to what you have in a headline / another headline etc. on the example image I posted in my initial questin?

It still displays # / ## etc. for me, but I use markdown, not org, so perhaps that's why.

The icons are not from this plugin. They are from https://github.com/akinsho/org-bullets.nvim But yes, it's orgmode only
