hey folks is Daniel here with another Python developer tip so I've got I term to here which is the terminal emulator that I use on my Mac and it's got a super super handy feature that allows you to click on any file name in the terminal and an open at in your favorite editor so check this out I've got a Python project here and I'm gonna kick off a test run with PI tests and before I started the recording I actually broke one of the tests and I get this wonderful printout from PI test right and now what I can do I can hit press down command and then click on that file name with the line number and what's gonna happen is that I term actually opens that file in my editor which in my case is sublime text 3 and it bounces me directly to the failed test case so did you see that right just command click into I term 2 and it's gonna open that file directly on that failed assertion based on the line number it can fix my test and run it again so this is a super super handy feature if you're running Python test from the command line like I do like it's kind of my workflow and it took just cuts down on the time that you need to actually find these test failures and then fix them now the cool thing is it doesn't just stop there so I can just do that with any file name right it doesn't have to be part of a test failure so even if I just run the LS command to list my files I can just click on any of those files and they're gonna be opened in the editor that I have configured which is super super useful it has another feature where if you click on a folder or directory it's actually going to open that folder in finder so you can browse it and I use that feature all the time it is so handy and now I'm gonna show you how to actually configure that so what you want to do is you want to open the preferences for item 2 and then click on profiles and then go all the way to the right to the Advanced tab from there you want to go to the bit that says semantic history and you want to use these settings so I have to set to open with editor and then I just picked my editor of choice which in my case is sublime text 3 so you can you know pick any editor that's in your Applications folder and it's just gonna gonna work and well then you close the Preferences and you're ready to go just try this feature out out it's actually really easy to setup once you find this setting which took me I know like a year to actually realize that I term 2 could do this and I was really glad I found this so I think I term 2 is actually a really great program that I use well basically every day in my development workflow and I probably gonna do more videos about that so if you're interested in this topic you want to learn more tips like that then either subscribe to my channel or actually go to debate org slash newsletter where which is my website I have a ton of free stuff for Python developers tutorials and videos just like the one you just watched and if you want to go there then and sign up for a newsletter and you're never gonna miss out on another video and I'd love to stay in touch with you cool thanks so much for listening I hope this was helpful have a great day
Original Description
iTerm2 has a little known feature that lets you open a file in your favorite editor simply by clicking on a file name in the terminal.
This also works with folders (they'll open in Finder) – and it is a super handy feature if you're running your Python tests from the command line. I use it all the time to click and jump to failed test cases with the Pytest test runner, for example.
(This feature should be completely language agnostic by the way. So you'll be able to use it with any test runner or language.)
The feature is called "Semantic History" and configuring it will let you Cmd+Click on any file or folder name to open it from the terminal.
Watch the video to learn how to set everything up :)
