Using grep crate (as library)

[bq-wrongway]

Hi,
i am having an issue that i am not sure how to solve :

    let matcher = RegexMatcher::new_line_matcher(&pattern)?;
    let mut searcher = SearcherBuilder::new().line_number(true).build();

I use something like this to create a searcher , and i use iced.rs to provide gui for search,

Then from UI, i select some directory or file, put in a word, and perform search which i can either save or present, even piping works, i can search just FOO or i can search FOO|BAR and it will find both words, but i dont see way to tell Searchbuilder (or matcher) to search ONLY rust files for example , -trust wont work.

I am not sure how would i be able to search only certain files, also going to grep create and checking grep_regex, grep_searcher i did not find way to add some extension filtering.
with cli is trivial, but with library is bit unclear.

Thank you

Yeah the high level documentation for "ripgrep as a library" is basically non-existent.

The problem here is that the grep family of crates are just for searching something. They don't help you with gathering what to search. You can do whatever you want to gather what to search. walkdir is a pretty standard implementation for directory traversal and you can apply your own filter rules at that level. The ignore crate is much higher level, uses parallelism, respects your .rgignore and .gitignore files and you can specify custom globs for filtering.
