4 This script takes a list of keywords and generates a testcase, that checks
5 if using the keyword as identifier fails, for every keyword. The generate
6 test files are set read-only.
7 Test for https://github.com/rust-lang/rust/issues/2275
9 sample usage: src/etc/generate-keyword-tests.py as break
18 // This file was auto-generated using 'src/etc/generate-keyword-tests.py %s'
21 let %s = "foo"; //~ error: expected pattern, found keyword `%s`

30 test_file = os.path.join(test_dir, 'keyword-%s-as-identifier.rs' % kw)
32 # set write permission if file exists, so it can be changed
