Execute against a string/buffer?

Is it possible to execute this against a string or buffer? Love the work, but would prefer not to write temp files :)

Start by reading the repository's command entry points and the current file-based input flow to determine how pipreqs receives and scans project sources. Clarify whether the requested string or buffer input belongs in the command interface or an underlying API; done should include a documented input path that avoids temporary files and coverage for it.
