Should I be able to use a forward slash in an expression?

Question

Should I be able to use a forward slash in an expression?

foconnor-DS opened this issue 3 years ago · 2 comments

I'm using handlebars to help write a generic data import tool. One of the test fields from the data file is:

Mailing State/Province

I'd like to refer to it, in an expression. I've tried:
{{[Mailing State/Province]}}
{{{[Mailing State/Province]}}}
Both fail to find the string key in the Dictionary<string,dynamic> I pass in.

Should this be valid syntax? I thought brackets were supposed to escape the off limits literals

Whitespace ! " # % & ' ( ) * + , . / ; < = > @ [ \ ] ^ ` { | } ~

The bracket escape seems to work for the other no-go literals i've run into.

Thanks.

Hello @foconnor-DS
You are right, [] should escape the literals and is treated as a single string.
If you can provide a test case it would be easier to find where the problem is.

Okay, I ran out of time this morning, but near as I can tell, all string literal notation is boken:

https://gist.github.com/foconnor-DS/7c991dff845e6ac1973e8534bb87c6b4

I wrote the code based on https://handlebarsjs.com/guide/expressions.html#literal-segments.

This test against the following notations:

[foo bar]
"foo bar"
'foo bar'
[foo!bar]
"foo!bar"
'foo!bar'
[foo"bar]
'foo"bar'
[foo#bar]
"foo#bar"
'foo#bar'
[foo%bar]
"foo%bar"
'foo%bar'
[foo&bar]
"foo&bar"
'foo&bar'
[foo'bar]
"foo'bar"
[foo(bar]
"foo(bar"
'foo(bar'
[foo)bar]
"foo)bar"
'foo)bar'
[foo*bar]
"foo*bar"
'foo*bar'
[foo+bar]
"foo+bar"
'foo+bar'
[foo,bar]
"foo,bar"
'foo,bar'
[foo.bar]
"foo.bar"
'foo.bar'
[foo/bar]
"foo/bar"
'foo/bar'
