Parse escape characters in string literals #7

Closed moleike closed 4 years ago

moleike commented 4 years ago

The parsing of strings in its current form is very incomplete.

A Jsonnet string is very much like a JSON string, but with some additional flexibility: string literals use " or '. Either can be used to avoid escaping the other, e.g. "Farmer's Gin" instead of 'Farmer\'s Gin'.

As a first step, we should handle:

escape characters \ + oneOf "'\/bfnrt
\uXXXX with 4 hex digits that encode the character's code point (we assume characters in the Basic Multilingual Plane for now)

If any doubts, please ask!
