regular expression #48

Closed caichencn closed 3 years ago

In source code file tidy.ts，I can not understand line 175，What is this regular expression searching for？

const yamlIndex = clangTidyOutput.search(/^---$/m);

Does it search for three consecutive ‘-’ ？ why?

Yes. If I remember correctly, clang-tidy outputs a bunch of human readable diagnostic information before the yaml that the extension needs. The three dashes mark the start of the yaml.
