Spacing of default values in macros

[EmilePerron]

Hey folks!

Looking at the Twig Coding Standards, there doesn't seem to be a set standard for defining default values in macros.

However, the official documentation for macros uses spaces around the = in its examples.

twigcs currently detects default values in macro definitions as named arguments, and request you use no space around the =. I'm not sure if this is a decision based on the lack of clear standard, or simply a bug.

If this is a bug or an oversight, I'd be happy to look into it and try to work on a quick PR to fix this. I'd just like to validate the desired standard here before getting started.

Steps required to reproduce the problem

1. Create a macro with a default value

    {%- macro render_a_thing(my_var = null) -%}
       {# some macro content #}
    {%- endmacro -%}

2. Run twigcs (vendor/friendsoftwig/twigcs/bin/twigcs templates)

Expected Result

No violation found.

Actual Result

l.1 c.31 : ERROR There should be 0 space before the "=" in the named arguments list.
l.1 c.33 : ERROR There should be 0 space after the "=" in the named arguments list.

Hi,

I think it's a bug ^^

Hello and thank you for reporting this. I think it's a duplicate of #170

I tried to look at the fix a few weeks ago and it's not that easy. We would need some improvement on the code that split parenthesis to make the difference between a macro declaration and other parenthesis (macro call, arithmetic expression, etc...).
