• Highlight field selections. For example, the size in this.size. Note that the highlighting isn’t based on semantics, it simply matches identifiers after a period.

Changes

• Set the scope of [ERROR] and [WARNING] to markup.bold as I found many VSCode themes does not colorize scope message.error.
• Set this, true, false, and null to the correct constant scope.
• Do not automatically close single quotations becuase they are also used in variable names and type variable names. (The notIn property of autoClosingPairs does not support user-defined scope names.)

• Highlight functions with user-defined symbolic operators (#177).

0.0.2

• Support folding error and warning blocks generated by DiffTests.
