Enhances `swift-syntax-test` to output the parser diagnostics so we can verify that if the incremental parse resulted in parser diagnostics, those diagnostics were also emitted during the full parse.

description='Utility for testing incremental syntax tree transfer',
|
|
epilog='''
|
|
Based of a single template the utility generates a pre-edit and a post-edit
|
|
file. It then verifies that the incrementally transferred syntax tree
|
|
matches the syntax tree passed as --expected-incremental-syntax-tree.
|
|
|
|
To generate the pre-edit and the post-edit file from the template, it
|
|
operates on markers of the form:
|
|
|
|
<<test_case<pre|||post>>>
|
|
|
|
These placeholders are replaced by:
|
|
- 'pre' if a different test case than 'test_case' is run
|
|
- 'pre' for the pre-edit version of 'test_case'
|
|
- 'post' for the post-edit version of 'test_case'
|
|
''')
