Is there any way to hide the separator for transparent windows?

[vishalbalaji]

I use this highlight to hide the nvim-tree separator.

vim.api.nvim_set_hl(0, "NvimTreeWinSeparator", { fg = "bg" })

This works fine when the background is opaque, but does not update for transparent backgrounds. Setting fg = "NONE" only makes the separator revert back to its default color. Is there any way to hide it in transparent windows or just an option to disable it?

Hint: you can use hitest.vim to show the actual values and a demo for all highlight groups :help nvim-tree-highlight

You can completely clear highlight groups and their links e.g. :hi clear NvimTreeWinSeparator

There are some nvim deprecation complications around the vertsplit / winseparator highlight groups, see: ##1221 . Result is two groups for nvim-tree and two groups for nvim, with default links between them.

Experimentation, rerunning hitest to see the results:

• clear NvimTreeVertSplit
• clear NvimTreeWinSeparator
• clear WinSeparator
• clear VertSplit
