How I tested this PR

I used Act to test Github actions locally

1. Prerequisite: docker
2. Install Act curl https://raw.githubusercontent.com/nektos/act/master/install.sh | sudo bash
3. Run ./bin/act -W .github/workflows/lint.yml
4. Check if the workflow runs successfully

Should --line-length still be 79? Or should I set it to 127 to match with flake8 config?

I found line length 79 that It is not enough for write text processing function but I don't sure that what the line length should be, so It should still be 79 until found the line length that enough for write text processing function.
