|

|
|
Parameters via Commas, Typed via Spaces:
|
||
|
|
|
||
|
|
> FunctionName ( type indentifier, type identifier = value, modifier type identifier )
|
||
|
|
> FunctionName ( indentifier, identifier = value )
|
||
|
|
|
||
|
|
The general idea is that parameters are separated by commas. Identifiers cannot contain spaces. Types and modifiers,
|
||
|
|
if available, are separated from the identifiers with spaces. There may be an equals sign to set the default value.
|
||
|
|
|
||
|
|
So parsing means splitting by commas, stripping everything past an equals sign for the default value, stripping everything
|
||
|
|
after the last space for the identifier, and the rest is the type. If there are no internal spaces after the default value is
|
||
|
|
stripped, it's all identifier.
|
||
|
|
|
||
|
|
Note that internal parenthesis, brackets, braces, and angle brackets should be parsed out. They may be present in default
|
||
|
|
values or types and any commas and equal signs in them should not be included.
|
||
|
|
|
||
|
|
Applies to C++, Java, C#, JavaScript, Python, PHP, Ruby.
|
||
|
|
|
||
|
|
Applies to Perl as well, even though it doesn't have any real parameter declaration structure. Just adding it with comments
|
||
|
|
is fine.
|
||
|
|
|
||
|
|
Parameters via Semicolons and Commas, Typed via Colons:
|
||
|
|
|
||
|
|
> FunctionName ( identifier: type; identifier, identifier: type; identifier: type := value )
|
||
|
|
|
||
|
|
Parameters via semicolons, types via colons. However, there can be more than one parameter per type via commas.
|
||
|
|
Default values via colon-equals.
|
||
|
|
|
||
|
|
Applies to Pascal, Ada.
|
||
|
|
|
||
|
|
|
||
|
|
SQL:
|
||
|
|
|
||
|
|
> FunctionName ( identifier type, identifier modifier type, identifier type := value )
|
||
|
|
|
||
|
|
Parameters separated by commas. Identifiers come before the types and are separated by a space. Default values are
|
||
|
|
specified with colon-equals.
|
||
|
|
|
||
|
|
> FunctionName @identifier type, @dentifier modifier type, @identifier type = value
|
||
|
|
|
||
|
|
Microsoft's SQL uses equals instead of colon-equals, doesn't need parenthesis, and starts its parameter names with an @
|
||
|
|
symbol.
|
||
|
|
|
||
|
|
|
||
|
|
Visual Basic:
|
||
|
|
|
||
|
|
> FunctionName ( modifiers identifier as type, identifier = value )
|
||
|
|
|
||
|
|
Parameters separated by commas. Default values via equals. However, any number of modifiers may appear before the
|
||
|
|
identifier. Those modifiers are ByVal, ByRef, Optional, and ParamArray.
|
||
|
|
|
||
|
|
|
||
|
|
Tcl:
|
||
|
|
|
||
|
|
> FunctionName { identifier identifier { whatever } } { code }
|
||
|
|
|
||
|
|
Identifiers are specified in the first set of braces and have no commas. However, they can be broken out into sub-braces.
