Google C++ style about guess-indent.nvim

[zhongsanming]

I don't know much lua or nvim plugin writing or ident detect, can we maybe just ignore access modifiers? Let say if a C++ line matches regex "^\s*(private|public|protected)\s*:\s*$", then skip this line.

Thanks for letting me know. I'm not yet sure how to best fix this issue.
I have an idea on how I could modify the heuristic, but I'm worried that it might make it worse overall.

I created a new branch with a modified heuristic which works better with the Google C++ style, though it still tails with the example you provided (it is too short).

Hey @zhongsanming, a fellow C++ Google Style Guide user here. I arrived here because of a different problem (in Neovim 0.8 without editorconfig.nvim plugin, the guess-indent.nvim failed to respect my EditorConfig -- now solved), but here's a solution we happily use in our codebase:

just add an .editorconfig to your root directory of the project, with approx the following content:

# EditorConfig is awesome: https://EditorConfig.org

# top-most EditorConfig file
root = true

# Unix-style newlines with a newline ending every file
[*]
end_of_line = lf
insert_final_newline = true
charset = utf-8
trim_trailing_whitespace = true

[*.{h,cpp}]
indent_style = space
indent_size = 4

AND in case you are under 0.9 version of Neovim, install gpanders/editorconfig.nvim so the guess-indent understands the buffer vim.b.editorconfig variable here

guess-indent.nvim/lua/guess-indent/init.lua

Line 272 in b8ae749

local editorconfig = vim.b.editorconfig

.

After that, the guess-indent should be good! My justification is that Google Style Guide is quite nontrivial in that part and having editorconfig anyways helps.

@agronskiy Thank you for this nice solution, I'll give it a try.
