Notes

This repository may not be feature complete and/or fully functional, Pull Requests that add features or fix bugs are certainly welcomed. For example this project converts integers only at this time, I.E. floating point numbers are not supported.

  • Fork this repository to an account that you have write permissions for.

  • Add remote for fork URL. The URL syntax is [email protected]:<NAME>/<REPO>.git...

cd ~/git/hub/javascript-utilities/decimal-to-base

git remote add fork [email protected]:<NAME>/decimal-to-base.git
  • Commit your changes and push to your fork, eg. to fix an issue...
cd ~/git/hub/javascript-utilities/decimal-to-base


git commit -F- <<'EOF'
:bug: Fixes #42 Issue


**Edits**


- `<SCRIPT-NAME>` script, fixes some bug reported in issue
EOF


git push fork main

Note, the -u option may be used to set fork as the default remote, eg. git push fork main however, this will also default the fork remote for pulling from too! Meaning that pulling updates from origin must be done explicitly, eg. git pull orgin main

  • Then on GitHub submit a Pull Request through the Web-UI, the URL syntax is https://github.com/<NAME>/<REPO>/pull/new/<BRANCH>

Note; to decrease the chances of your Pull Request needing modifications before being accepted, please check the dot-github repository for detailed contributing guidelines.

Notice, edits to source code should target .ts (TypeScript) files, because JavaScript (.js) files are overwritten during transpiling process.
