13.2 Indentation

Optional "begin" - Some language constructs, for example the conditional statement if or the loop statement for, require a begin - end block to control the execution of several statements. Such blocks are called optional "begin" in order to distinguish them from other cases like fork begin ... end endfork' or plain begin ... end blocks used just for grouping several statements together for readability. This option affects the optional "begin" blocks:
- Leave as is
- On a new line - begin is moved on a new line
- On the same line - begin is moved on the same line with it's construct
- On a new line and indent - begin is moved on a new line and indented

Initial code	Leave as is	On a new line	On the same line	On a new line and indent

"else" - This option affects else placement:
- Leave as is
- On a new line - else is moved on a new line
- On the same line - if end precedes it else is moved on the same line with end

Initial code	Leave as is	On a new line	On the same line

Parameters - This option affects module ports and parameters, function and task arguments, class parameters:
- Leave as is
- One per line (open parenthesis on the same line) - each parameter/argument is placed on it's own line and the open parentheses is placed on the same line with the parameter/argument receiver
- One per line (open parenthesis on the next line) - each parameter/argument is placed on it's own line and the open parentheses is placed on the next line after the parameter/argument receiver
- More per line - more are placed on the same line, as fit when line wrapping is enabled

Initial code	Leave as is	One per line (open parenthesis on the same line)	One per line (open parenthesis on the next line)	More per line

Preprocessing - This option affects `ifdef blocks:
- Leave as is
- Indent - indent, but don't increase the enclosed statements indentation
- Indent and increase indentation level - indent like any other scope language construct that increases indentation of it's enclosed statements
- Indent and increase indentation level except first - indent the preprocessing block according to the enclosing scope and increase the enclosed code indentation with the exception of the first nested preprocessing block
- Move at first column - move at line start, but don't increase the enclosed statements indentation

Initial code	Leave as is	Indent	Indent and increase indentation level	Indent and increase indentation level - except first	Move at first column

Don't indent single line comments at first column - This option affects single line comments that start at column zero. It is useful to disable the indentation for whole regions of code that are block commented, for example by using Ctrl + /. When enabled, single line comments that start at column zero are not indented.

Indent multi-line comments - This option affects multi-line comments ( /* ... */). When enabled, multi-line comments are indented.

Before	After

Do not indent multi-line content of assigns - When enabled, the assign lines are not indented such as to preserve an alignment.

Before	After

Add New Line After Begin And Before End - Controls whether to add a new line after `begin` and before `end`.

Ignore lines starting with- Space separated list of line prefixes. A line starting with one of the prefixes is completely ignored, that is it is not indented, nor it contributes to indentation.

Before	After

Don't increase the indent Level On - By default all scope language constructs increase indentation. This option allows you to control which language constructs should increase indentation.

Before	After ("assert" keyword)

Implicit semi macros - The code formatting engine depends on detecting some delimiters for properly identifying the proper indentation scope, for example indentation should not increase after if(a) foo1();, but it should after if(a) begin foo();. Semicolon or end is such a delimiter and sometimes it may be encapsulated inside a macro. This option allows you to explicitly list such macros for proper code formatting.

Before	After

Open/Close scope macros - An open scope macro increases the indentation level of subsequent code to visualize scoping. A close scope macro decreases back the indentation level. Open/close scope macros are paired, for example: `TEST and `ENDTEST, similar with language keywords like function and endfunction.
