I wanted to use a ruby environment inside a Ubuntu VM but still be able to edit text files in Textmate. So I shared out my project folder and fired up a watchr script I made. Unfortunately, it didn’t work at all.
I tried a few different libs, including rev, rb-inotify, rb-fsevents (which turned out to be mac only) but nothing was firing when I’d save a file. I thought maybe rev or watchr was broken in 1.9 but that was not the case. The problem is the vmware shared folders. When you do a write, modify or whatever, it doesn’t fire the same hooks as a local event does: ` Modify File -> Textmate Save -> project/foo.txt (does not fire in watchr) Modify File -> Vi Save in VM -> project/foo.txt (watchr fires) `
And it wasn’t just watchr (as I said), every ruby library was seeing the same thing. So I gave up on the shared folders through VMware and just installed netatalk.
sudo aptitude install netatalk
I can edit files in Textmate this way and watchr works as expected. So why is this important? Because a tight REPL is important. And watchr / wtchr makes the tight loop happen. This is also probably going to happen if you use autotest in a project with lib/* test/* too.
Pretty specific but I hope it helps someone.
