Statusline isn't working as expected

[wincent]

You should be able to debug this by strategically inserting some print(vim.inspect(value)) statements right before the lines where the error is being thrown. You'll probably find that in a spot like this (not sure if this is the exact spot that is error, but it will be something like this):

local fg = pinnacle.extract_fg(status_highlight)
local bg = pinnacle.extract_bg("StatusLine")
print(vim.inspect(fg))
print(vim.inspect(bg))
vim.cmd("highlight User4 " .. pinnacle.highlight({ bg = bg, fg = fg }))

If, say, fg or bg ends up being an empty string, that could cause the :highlight command to error, and so the next step is debugging why the associated highlight group (eg. StatusLine, or Identifier etc) doesn't have that set.

I'm using base16-vim, and I find that all the highlight groups have defined values. In your local set-up, something else must be happening; fixing it might mean doing something to the colorscheme, or to your statusline.lua file.

I'm currently using TreeSitter and when I try to implement the blur/focus methods you use, I can't get TreeSitter disabled for the inactive buffers. How would you deal with this?
Also, how would I add the gps to the statusline right after the file type next to the filename?

I'm not using either of those, so I don't have any specific advice to offer about them.

After a little digging, I found the issue. For some reason, when using the pinnacle plugin, the highlight variable was being set to: ctermbg=#505050 ctermfg=#d0d0d0 gui=italic. So, I just added :gsub("cterm", "gui") at the end of each line when modifying the highlight variable.

I'm going to keep this issue open since I'm currently working on getting the statusbar to work with gps and to get TreeSitter working along with the focus/blur method. Once I've completed these tasks, I'll post my results here and close the issue, just in case anyone else wants the same.

Alrighty. I just completed the gps part of the statusbar. Here's how the statusbar looks like.

Here's the code (I put this right after: .. "%)" -- End item group.)

      .. "%*" -- Reset highlight group.
      .. "%3*" -- Switch to User3 highlight group (bold).
      .. "%= %<%{%v:lua.require'nvim-navic'.get_location()%} %=" -- Navic in Center.
      .. "%*" -- Reset highlight group.

Of course, to get this working, you need to have nvim-navic installed and configured.
Here's my configuration for nvim-navic.

I'll try and get the TreeSitter + focus/blur done today and close this issue as soon as possible.

Finally. I figured out the final issue. I disable TreeSitter and IndentLine by adding the following autocmds:

autocmd("BufEnter", "*", "TSBufEnable highlight")
autocmd("BufEnter", "*", "IndentBlanklineToggle")
autocmd("BufLeave", "*", "TSBufDisable highlight")
autocmd("BufLeave", "*", "IndentBlanklineDisable")

This does bring about the following issues. When opening something like a float, it disables highlighters and indentation, but after leaving, it doesn't bring them back.

@wincent How would you create an autocmd that only triggers when leaving a buffer, and then re-entering another buffer?

Unfortunately, autocmds are notoriously fiddly, especially once you have multiple plug-in installed, firing autocmds, listening to autocmds, suppressing autocmds (eg. with :noautocmd, 'eventignore') etc. I don't really have any generic advice here, other than using 'verbose', :verbose, 'verbosefile' to capture debug information about what events are being triggered, and in what order, and to work from there.
