[stringtemplate-interest] [ST4] How to avoid map key iteration?

[Sam Harwell]

Hi Udo,

 

The problem is the operation in use when you write it the way you originally
did - the ':' is a map operation as opposed to a pass to a function method.
In theory, the following syntax could solve the problem:

 

t2(adr,line2={x|<x.zip> <x.city>}) ::= <<

<adr.firstname> <adr.lastname>

<line2(adr)>

>> 

 

I know this syntax doesn't work in ST3, and I'm guessing it doesn't in ST4
either. Considering the way parameters and local variables work in many
languages, I don't think allowing this would be unexpected.

Hi Sam,

 

If you write it this way:

 ...

 <t2(adr=p,line2={<adr.city>, <adr.zip>})>

 

Good point.

 

I guess it is just my personal style (and background) that makes me raise
the issue. Inside a subtemplate I'd prefer to access the parameters of the
subtemplate (the {p1,p2|.}) over the access of something outside of the
subtemplate, especially with the dynamic name lookup of ST4 in mind.

 

 

Udo
