How do I escape ( and ) in rulesets?

For that matter, using the example from the language reference, how do you escape comma?

* insert Question(tr1, When did you leave?, date, false)

can't you just use \ to escape whatever you want?

ah, according to my own fsh testscript resources, you only need to escape the end parenthesis..

* insert AssertExpression ("Observation.exists(\)", false, "Expected: Pass")

From the current build of the spec:

As indicated, the list of values is enclosed with parentheses () and separated by commas ,. If you need to put literal ) or , characters inside values, escape them with a backslash: \) and \,, respectively. White space separating values is optional, and removed before the value is applied to the rule set definition.

I was escaping the ( as well... Thanks

I assume that you also need to escape backslash?

Ah. Good point. I think you're probably right about that, but would need to take a look at the code to confirm. But assuming you're right, we should probably update the doc to reflect that. Thanks!

OK, I think you're right. Escape \ with \ (i.e., \\). Simple example: https://fshschool.org/FSHOnline/#/share/3tnx1cc

Should I be seeing something with that link?

the school links works fine for me, shows that insert DoShort(he\)l\,l\\o) resolves to "short":"he)l,l\o"

Hmm, interesting. Works in Chrome, but not in Safari.

Oh, dang. Yeah, that behavior on Safari is not acceptable. Yikes. We'll have to take a look at that.
