[stringtemplate-interest] Generating JSON using StringTemplate

[Udo Borkowski]

Hi Piotr,

you don't need to add the 'format="…"'  in many many places. Just create one template containing the formatted string rendering and use that template instead of the '…' stuff.

E.g. create a template "q" (for "quote")


> q(s) ::= <<
> <s;format="singleQuote">
> >>
> 
> main(user) ::= <<
> {
>    firstName: <q(user.firstName)>,
>    lastName: <q(user.lastName)>
> }
> >>

This will output:

> {
>    firstName: 'Joe',
>    lastName: 'O\'Donovan'
> }



Depending on the concrete application I would also consider adding a template to render both the key and value:

> kv(key, value) ::= <<
> <key>: <value;format="singleQuote">
> >>
> 
> main(user) ::= <<
> {
>    <kv("firstName",user.firstName)>,
>    <kv("lastName", user.lastName)>
> }
> >>
