How to specify clang-format indendation for Eclipse C++ LSP editor?

[kevin071586]

Hi,
I'm trying to switch over to the Eclipse C++ LSP editor and would like to figure out how to fix up my automatic indentation. It seems like I'm always getting 4 spaces for an indent -- for example on the line after the opening brace of a new function, despite having specified in my .clang-format file:

BasedOnStyle: Google
IndentWidth: 2
TabWidth: 2
UseTab: Never

I'm somewhat new to the clang-format configuration so maybe have mixed something up. This .clang-format file is in a parent directory of the file I'm editting. I don't see any other configurable preferences for tabs in Eclipse (for the LSP editor) and don't have indentation specified anywhere else that I'm aware of. What might I be doing wrong?

Thanks,
Kevin

Hi Kevin,
you have to (currently) distinguish between the settings while writing code and auto formatting. The first one has to be done in Window -> Preferences -> Editors -> Text Editors:

The .clang-format settings come into play when the file gets formatted on file save (if it's enabled) or if you format the code manually via Source -> Format:

Thanks, I had the "insert spaces for tabs" box ticked but I had left the "4" in the "Displayed tab width" because I was under the impression it only affected how "tabs" would be displayed. It seems that this setting also has a side effect of how many spaces are inserted in place of a tab. This works for me, thanks!
