--semgrepignore-filename

Accepted by

opengrep scan

Value

FILENAME

Default

.semgrepignore

See also

--exclude, --use-git-ignore, --project-root

Opengrep skips the paths listed in .semgrepignore at the project root. This flag reads the list from FILENAME instead.

The file uses the pattern syntax of .gitignore. When the project has no such file, a built-in list applies, which skips directories such as node_modules/, vendor/, test/ and tests/. The project root is set by --project-root.
