TCR lets you instantly use the test && commit || revert method of software development on your project. TCR watches your files, and when you save any file, the tests are run, if they pass the change is committed if it fails the code is reverted.
Poof! The failing code is gone.
TCR helps you think of the smallest possible changes you can make, without ever having broken code hanging around.
TCR runs on Windows, Linux and Mac. First install node, then run npx tcr 'my test command' and you will be up and running.
- No installation necessary
- Each save runs your test command. If it passes it's committed, if it fails it's reverted
- Failure messages are kept in the console, rather than overridden by the next test run
.gitignoreis respected to prevent watching compiled files- Stats on commits and reverts are shown along with the most recent file change detected
- Cross-platform for Windows, Linux and Mac
TCR is reliant on editors respecting changes on disk.
| Editor | Supported? | Notes |
|---|---|---|
| VS Code | ✅ | You may have to disable some plugins like Prettier which interfere with listening to changes |
| Atom | ✅ | |
| Sublime Text | ✅ | |
| Vim | ✅ | You need to install the autoread bundle to get reloading to work without a prompt |
| IntelliJ suite | ❌ | IntelliJ doesn't like external apps changing things, instead use the limited wip plugin by Dmitry Kandalov |
