Subject [jira] [Commented] (PIVOT-960) Implement simple macro system in JSONSerializer
Date Wed, 05 Nov 2014 08:24:34 GMT

Sandro Martini commented on PIVOT-960:
--------------------------------------

Hi Roger,
now I think your last proposal is better because $name is good but for variable substitution
in a specific context (inside a delimited string or a page tag) ... but if it's not a problem
I'd prefer the ${name} , as you said aligned with Ant syntax, and aligned with tag in jsp/other
web pages.

> It occurred to me since we are using JSON style sheets to style our application, and
it is getting quite big, that a macro system (maybe similar to C/C++ with #define or something
similar) would be useful, especially for repeated colors, and other constants (like padding
values, fonts, etc.)  This would enable using custom values consistently while avoiding inconsistencies
due to typos or changes introduced one place and not others.
> I was thinking of a simple
> #define NAME value
> as in C/C++, and then using $(NAME) as the substitution token.  This is easily implemented
in JSONSerializer.
> I'm open to suggestions for the syntax, but I believe the feature will be very useful,
especially for the JSON stylesheet.
