When changing a function/type/field from unexported to exported, or visa versa, generally you will use vim.lsp.buf.rename and:
- Go to the start of the line
- Change the word from upper-case to lower-case, or visa versa
- Hit enter
This very small plug-in exposes one function that toggles between exported and unexported. Simply :lua require('toggle_export').ToggleExport()
Note: This only currently works for language that mark things as exported/unexported based on the first letter casing (e.g. Go).
