This makes it possible to run the spec parser in a way which is a bit more like the other tools that we have (e.g., tools/test.py): > tools/spec_parse.py tests/language/callable_test.dart It still requires the developer to run `make parser` in tools/spec_parser and hence does not run on a buildbot, but it's one step forward.

# This script runs the parser which is generated using ANTLR 3 from
|
|
# docs/language/Dart.g. It relies on a certain environment and is hence
|
|
# usable locally where this environment can be obtained, but it may not be
|
|
# possible to run it, e.g., on build bots. The requirements are as follows:
|
|
#
|
|
# - `make parser` in spec_parser has been executed successfully.
|
|
# - A suitable JVM is in the PATH and may be executed as 'java'.
|
|
# - the ANTLR3 jar is available as /usr/share/java/antlr3-runtime.jar.
