Last night I decided to bite the bullet and start to re-learn clojure with the intention of adopting it as my web stack for personal projects. I had been curious about Light Table, so I started there.
If you haven’t heard of Light Table, it’s a new IDE concept that is best seen rather than explained:
Soon after this video, they raised money from KickStarter and YCombinator, and now we’re starting to see some progress. v0.2.0 was released earlier this month.
Light Table is really rough right now — you can see the potential, and it’s totally not fair to judge it now, but here are my quick reactions (I’m totally ignoring all buggy behavior, as that’s very expected):
- It’s somewhat unfriendly to start with if you already aren’t working on a clojure project. After a few minutes, I realized I really needed to get Leiningen working first, generate out a project, then use Light Table on the generated files.
- The app is not signed, which Mountain Lion complains about — not a huge deal, but look at their website — they are projecting a nice brand and attention to details — getting this warning makes me think “side-project”. It’s easy to fix.
- Error messages comes up in a pane that isn’t resizable and not big enough. With how good Light Table looks, this pane is out of place, and makes using it on something real very frustrating.
- It’s slow in ways that are unexpected (like saving a file)
- Keyboard-oriented commands
- Surprisingly good text-editing
- The instarepl integration is slick — as is the in-editor form evaluation
- Very nice looking — which is part of the reason I’m picky on the more rough parts.
In the end, it was Light Table that gave me the push to go back into clojure, but I wonder if I can stick with it. The other options are worse (for me) — I can’t imagine using Eclipse, I don’t know Emacs, and the simpler editors don’t have any repl integration.
Top two reasonable feature requests
- Let me highlight a form and execute it
- Some better way to show errors (probably don’t try to put it off to the side right now)
