Indentation change icon into ">>"

[rhesadaiva]

Problem

Hello, i have an old PHP project which i need to maintain, when i open the file for the first time, it shows the default indentline "|"

When i do some editing and save, the indentation change into ">>"

Steps to reproduce

And for the colors, i create a custom color palette which code like this

Expected behavior

It should return a normal indentline instead of ">>"

Neovim version (nvim -v)

0.9.5

The file probably gets formatted when you save, and the indentation changes from spaces to tabs. Take a look at :help ibl.config.indent.tab_char to configure how tabs get displayed.

This is happening to me on file open, not save, so it's not a format issue. But it only seems to happen for some languages. LUA seems fine, Go does not for example.

It doesn't happen after formatting for you because your file is already indented with tabs.

This is the correct behavior, please read :help ibl.config.indent.tab_char

So what you're saying is the intended behavior is to only show solid lines for space indented files? I've read the 2 help lines mentioned, it doesn't help explain the intended behaviour.

How spaces are displayed is configured with ibl.config.indent.char. How tabs are displayed is configured with ibl.config.indent.tab_char.

If you do not set ibl.config.indent.tab_char in your config, it defaults to :help lcs-tab if :help 'list' is set, otherwise it uses ibl.config.indent.char.
You have 'list' set, and tab in listchars set to >>. So that is what ibl is using.

This is explained in the help file.
