Format function

[Bas van der Vlies]

I just want to use a function in format(), eg:
* "$(this.bundle): $(with)" with => format("bas %S", readdata("$(template_dir)/$(json_files)", "auto"));

I get all kind of errors:
{{{
error: format() didn't have enough parameters
}}}

The question is this an error or is it not allowed?

Which version of CFEngine are you using?

{
   "Hello": "World"
}

Hi Bas,

It seems like the format() function doesn't accept functions as input yet. Can
you open an issue for this. I believe that the format() function needs
"collecting" behavior.

bundle agent main
{
   reports:
     "CFEngine $(sys.cf_version)";

     "$(this.bundle): $(with)"
        with => format("BAS %S", readdata( "/tmp/example.json", "auto" ));
}

   error: format() didn't have enough parameters
   error: format() didn't have enough parameters
R: CFEngine 3.11.0
   error: format() didn't have enough parameters
   error: format() didn't have enough parameters
R: main: $(with)
   error: format() didn't have enough parameters
   error: format() didn't have enough parameters
   error: format() didn't have enough parameters
   error: format() didn't have enough parameters

Here are some alternate patterns that work as expected with nested functions.

bundle agent main
{
   vars:

     "d" data => readdata( "/tmp/example.json", "auto" );

   reports:
     "CFEngine $(sys.cf_version)";

     "$(this.bundle): $(with)"
        with => format("BAS %S", d );

}

R: CFEngine 3.11.0
R: main: BAS {"Hello":"World"}

bundle agent main
{
   vars:

     "d" data => readdata( "/tmp/example.json", "auto" );

   reports:
     "CFEngine $(sys.cf_version)";

     "$(this.bundle): $(with)"
        with => string_mustache("BAS {{$-top-}}", d );

}

R: CFEngine 3.11.0
R: main: BAS {"Hello":"World"}

bundle agent main
{
   reports:
     "CFEngine $(sys.cf_version)";

     "$(this.bundle): $(with)"
        with => string_mustache("BAS {{$-top-}}", readdata( "/tmp/example.json", "auto" ) );

}

R: CFEngine 3.11.0
R: main: BAS {"Hello":"World"}

Thanks a lot Nick for this suggestion. Very useful the ‘string_mustache’ and easy ;-)

Yes, and don't forget about {{%-top-}} (multi-line JSON representation)
