Any option to make nvim-tree window keep current window width when opening another file from nvim-tree?

[ljie-PI]

Sometimes name of files are long and I change the width of the nvim-tree window to view the full names. Then I may open that file from nvim-tree. The nvim-tree window gets reset to pre-defined width after I open the file, and I need to resize the nvim-tree window again to see the full name of files.

Is there an option that can let nvim-tree window keep the width?

You have a lot of options for width, including a function to define whatever behaviour you want. See :help nvim-tree.view.width

You could try dynamic width: set a min and max to suit.

I have a mapping A that toggles between fixed width 30 and unlimited (adaptive) width: https://github.com/alex-courtis/arch/blob/master/config/nvim/lua/amc/plugins/nvt.lua#L103

Thanks @alex-courtis . I see your are switching between VIEW_WIDTH_FIXED and -1. Does "-1" means current width? I tried directly using -1, but seems not working as expected.

[alex-courtis]

-1 indicates unbounded - fit to the longest name.

I usually use it, however must turn it off for deep codebases, such as java.

If you're having trouble getting functions etc. going, you could try hardcoding to demonstrate the functionality:

  view = {
    width = {
      max = -1,
    },
  },
