Release Notes

0.0.6

Features

• Highlight type in class Foo[type A].
• Highlight nested DiffTests flags (e.g. :ducs:postprocess.result).

Fix

• Include trailing single quotes as a part of entity names.
• Recognize trailing single quotes as a part of words. So, if you press ⌥← or ⌥→, the editor will select names including the trailing single quotes.
• Comments can follow DiffTests flags.

0.0.5

Features

• Support hexidecimal, octal, and binary integer literals. #199
• Support floating-point decimal literals. #199

Fix

• The rule for parameter lists should not be at top-level.
• Highlight some keywords even they are not in a valid declaration.
• Highlight keyword rec.
• Highlight normal variables.

0.0.4

Additions

• Highlight modifiers declare and virtual for function declarations.
• Highlight modifiers declare, private, abstract, and data for class declarations.
• Highlight modifier private for trait declarations.
• Highlight modifiers declare and private for module declarations.
• Highlight mixin declarations.
• Highlight keyword super.
• Highlight modifiers declare and virtual for function declarations.
• Highlight val declarations with modifiers declare, private, and lazy.
• Highlight in/out variance modifiers and type variables starting with a single quote in parameter lists.
• 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.)

0.0.3

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

0.0.2

• Support folding error and warning blocks generated by DiffTests.
• Add two simple snippets. I'm just trying it out.
• Fix minor bugs.
