indent_size = tab - what does it mean?

[Harold Tessmann]

Either I need more caffeine, or the documentation at <https://github.com/editorconfig/editorconfig/wiki/EditorConfig-Properties#indent_size> is unclear. What would it mean if you set indent_size = tab?

It means an indent should be a tab.

[Harold Tessmann]

Isn’t this redundant with indent_style = tab, though? What would happen if I did:

indent_style = space

indent_size = tab

It seems like the only acceptable value for indent_size should be numeric, and indent_style alone should determine whether to use a tab character or spaces.

It could be the case that indent_style is tab but indent_size is a
number. In this case, tab fill most of the indent and spaces fill the
rest when tabs are too wide. This could happen to some projects such as
GCC and Vim. However, if indent_size is not specified an indent_style is
tab, it defaults to tab.

The semantics of indent_size = tab is not clear to me after reading this thread. 

Hong Xu, could you please 

(1) document indent_size = tab in https://github.com/editorconfig/editorconfig/wiki/EditorConfig-Properties#indent_size 

and 

(2) add a few tests with concrete data somewhere that will show clearly what the various combinations of indent_style and indent_size are supposed to do?

Thanks,

Hi Peter,

The explanation is in this page:

http://docs.editorconfig.org/en/master/editorconfig-format.html

A test case is available here:

https://github.com/editorconfig/editorconfig-core-test/blob/master/properties/indent_size_default.in

Thanks,
Hong

I have now added the explanation to the wiki page. Thank you for
pointing this out.
