Indent configuration not working for C++

[Ha5hBr0wn]

Hi I am using the Helix text editor and my indents in C++ are just 2 spaces and I want them to be 4. I can't figure out how to make it work

I have been adding the indent to the languages.toml file as the docs tell me to:

[[language]]
name = "cpp"
auto-format = true
formatter = {command = 'clang-format', args= ["--style=Google"]}
indent = { tab-width = 4, unit = "    " }

I was on version 20.05 at first and I also tried on latest master but I alway just get 2 spaces in auto indent and when I press tab

I know the languages.toml file is getting picked up because if I change the style for the formatter that does take effect as expected. So just the indent key is not working as expected for me

If you have a file that already has an indent of 2 spaces, you will have 2 spaces despite your configuration. Try in a new file or format yours with 4 spaces manually (or using formatter).
Fyi, this configuration works for me:

 [[language]]
 name = "c"
 indent = { tab-width = 4, unit = "    " }
 [[language]]
 name = "cpp"
 indent = { tab-width = 4, unit = "    " }

Do you have 2 spaces identation only after saving file or even on typing?

Bro, it is now 2024, wake up)

I just noticed that my C++ code (both existing and new files) are using two spaces instead of four (which is what they used to have). How do I change this? I just added

indent = { tab-width = 4, unit = " " }

but it doesn't seem to have any effect.

This is helix 24.7 (30fb63cc).

It should work with new files. In older files it will detect that there is indentation = 2 and will not even look at your config.
Workaround: manually convert tab 2->4 on old files.

It doesn't work with new files. I wonder if it's clang-format that's causing the issue.

# languages.toml
[[language]]
name = "cpp"

[language.indent]
tab-width = 4
unit = "    "

[[language]]
name = "c"

[language.indent]
tab-width = 4
unit = "    "

The pasted config does not work.

Solution 1: create new file, write some code that use 4 space as indentation, close it. Then open it with helix, it use 4 spaces now.

Solution 2: create new file with helix, type :indent-style 4 command, then write code as usual since it use 4 spaces now.
