No indent in LUA files about treesj

[Wansmer]

Hello, I think, you have 'shiftwidth' equals 0 for filetype 'lua'.
Indent calculating on value of 'shiftwidth'.
Try :lua =vim.bo.shiftwidth. If it will be '0', set option shiftwitdh bigger than 0 in your init.lua.

Thank you for the quick response.
Yes it's true i have shiftwith = 0 because when zero, it defaults to tabstop. And I have tabstop = 4.
Interestingly, when inside e.g..js or .py files, the indent works properly with shiftwith = 0. Is this intended, that .lua files are treated differently?

Setting shiftwith to 4 would solve my problem, however I like having shiftwith bound to my tabstop. If it's not too complicated, I'd love to see a fix but otherwise i'll just change my shiftwith value.

Great plugin by the way ❤️

Thanks for feedback.
I not sure what it needs to be fixed, because shiftwidth is a default for builtin neovim indent engine.

Try set expandtab to false – it will save tabs instead of spaces and you can use shiftwidth.

Is this intended, that .lua files are treated differently?

I think, it sets by neovim's directly. Neovim have builtin preset for different filetypes.

Yes it's true, shiftwith is a default. However you can not take that value literally.

Output from :help shiftwith:

Number of spaces to use for each step of (auto)indent.
Used for 'cindent', >>, <<, etc. When zero the 'ts' value will be used.

That means, whenever shiftwidth is set to zero, the true value of shiftwidth is the value of tabstop. The zero just denotes, that tabstop and shiftwith are bound together.

You're using the shiftwidth literally in two palces:

treesj/lua/treesj/utils.lua

Line 368 in 023db2f

local shiftwidth = vim.api.nvim_buf_get_option(0, 'shiftwidth')

treesj/lua/treesj/treesj/init.lua

Line 72 in 10aed3c

local sw = vim.api.nvim_buf_get_option(0, 'shiftwidth')

An additional check like the following would solve the issue:

if shiftwidth == 0 then
    shiftwidth = vim.api.nvim_buf_get_option(0, 'tabstop') 
end

I'd do a PR, but i don't understand the logic of your plugin. Do when do you use the calc_indent() and when the build_tree() function? Do you need to change it in both places? I guess you have a better understanding of that.

You're right with that. The global value was overwritten by ftplugin. Thanks for the clarification

That means, whenever shiftwidth is set to zero, the true value of shiftwidth is the value of tabstop. The zero just denotes, that tabstop and shiftwith are bound together.

I use shiftwidth in a logic way – because it about indentation. tabstop it only about width of tabulation.
I'll learn a little more about interconnections of tabstop and shiftwidth. At the moment, sw looks the best values for use.

The shiftwidth() function returns the effective value of 'shiftwidth'; see :h shiftwidth().
