Constant Summary collapse

JSONC_TOKEN =

Matches either a JSON string literal (with escapes), a line comment, a block comment, or a trailing comma. The alternation lets gsub preserve strings while stripping the JSONC-only constructs, so e.g. “//” inside a URL value is not mistaken for the start of a comment.

T.let(
  %r{
    ("(?:\\.|[^"\\])*")    # JSON string literal
    | //[^\n]*             # line comment
    | /\*.*?\*/            # block comment
    | ,(?=\s*[\}\]])       # trailing comma
  }mx,
