Hi, I totally agree that most important is to have a consensus. And apparently the majority of the community prefer to use tabs. I asked because all the coding standards I looked at recently use spaces instead of tabs:
- Moodle http://docs.moodle.org/en/Development:Coding_style#Indentation
- Zend Framework http://framework.zend.com/manual/en/coding-standard.php-file-formatting.html#coding-standard.php-file-formatting.indentation
- PEAR http://pear.php.net/manual/en/standards.indenting.php
- Python http://www.python.org/dev/peps/pep-0008/
But after a quick search I found other important free software project that use tabs (just as an example):
- Wordpress http://codex.wordpress.org/WordPress_Coding_Standards
I have just one more doubt. The PEAR coding standard mention that they use spaces to avoid problems with tabs when performing diffs. There are some tips to use tabs and do not run into trouble with diffs? As I'm not used to use tabs I'm not even sure what kind of problem could be, if there are any.
I propose that we clarify the reasons why we use tabs on dev.tikiwiki.org. I will try to organize something during this week. Maybe creating a page for coding standard and on this page explain why we use tabs and also give some tips on how to properly configure some popular editors to use tabs. It might also be a good idea to think of ways to make it clear that we do have a coding standard (I bet that a good part of Tikiwiki developers didn't know that we have one, including myself a few days ago).
The numbers I mentioned about how much of the code use spaces and how much use tabs are not precisely (for example, as mentioned by Sylvie, they include the Zend library which is huge and use spaces for indentation) but they do show that we have a mix of both on Tikiwiki code. So we might consider again some code cleanup.
