Subject: [FEATURE] Switch to PSR-2
X-Git-Tag: 3.0.0~17
X-Git-Url: https://git.p6c8.net/jirafeau_mojo42.git/commitdiff_plain/96707e02b8b24054e0827eaf169cc88504a1e78c

[FEATURE] Switch to PSR-2

Convert all PHP files to PSR-2, which defined
a basic Coding Style Guide for PHP projects.

Using the awesome friendsofphp/php-cs-fixer tool,
running with the @PSR2 ruleset.

1) script.php (no_spaces_after_function_name, braces)
2) f.php (indentation_type, no_spaces_after_function_name, braces)
3) install.php (indentation_type, function_declaration, elseif, no_spaces_after_function_name, braces)
4) lib/functions.php (no_spaces_inside_parenthesis, method_argument_space, function_declaration, elseif, no_spaces_after_function_name, lowercase_constants, lowercase_keywords, braces, single_blank_line_at_eof)
5) lib/functions.js.php (no_spaces_after_function_name)
6) lib/lang.php (function_declaration, no_spaces_after_function_name, lowercase_constants, no_closing_tag, braces, single_blank_line_at_eof)
7) lib/template/footer.php (braces)
8) lib/config.local.bak.php (method_argument_space, no_spaces_after_function_name, no_closing_tag, single_blank_line_at_eof)
9) lib/config.original.php (no_spaces_after_function_name, no_closing_tag, single_blank_line_at_eof)
0) lib/settings.php (indentation_type, no_spaces_after_function_name, braces)
1) lib/config.local.php (no_spaces_after_function_name, single_blank_line_at_eof)
2) index.php (indentation_type, no_spaces_after_function_name, braces)
3) admin.php (no_spaces_after_function_name, braces)
4) tos.php (no_spaces_after_function_name, no_closing_tag, single_blank_line_at_eof)
