The idea for lazybuilder came up during a recent coding dojo doing code kata. We were using Vim and a separate terminal to run the tests. Switching back and forth between two windows when trying to move quickly seemed like a waste of time.
There are several tools in this space but most of them work by polling for changes or use linux events that are not available on a mac. lazy builder uses CoreServices.
I found during testing with a rails app that some events are received after the build has completed. To avoid looping I added a 100ms delay after a build. This is a bit of a hack and I am working on trying to recognize changes that are due to build activity as an alternative.
with no parameters watches the current directory and runs make.
lazybuilder . rake
watches the current directory and runs rake
If you want to run more complex build commands enclose them in quotes:
lazybuilder . "raake test"
- Improve cool down period
- Avoid triggering build on temp file changes generated by emacs
- Consider committing changes to version control (particularly git) if the build command is successful
If you get to try out lazy builder I would really appreciate feedback, bug reports and pull requests.
