Re-brand! One Man Band is now shellflow.dev
As I build this tool, I'm spending most of my dev time in it. This means it's becoming less of just a worktree manager for LLM tools and more of a general-purpose terminal wrapper that includes workflow tools.
Still iterating and discovering new uses!

Released One Man Band 0.2.0. It's now capable enough that I'm using it to build itself alongside another project. Terminal notifications, progress, task running, and of course worktree management.
Now installable via brew (my tap, for now — check instructions).

I'm actually surprised that this is not a syntax error in Ruby
>> x = [foo: "bar", baz: "boo"]
=> [{foo: "bar", baz: "boo"}]
>> x = [foo: "bar", baz: "boo"]
=> [{foo: "bar", baz: "boo"}]

If you're writing API documentation, always specify units for duration parameters.
Not just "timeout: 30" but "timeout: 30 seconds" or better yet name the parameter if you can "timeout_in_seconds"

Working with LLMs means reviewing way more diffs than before.
I discovered delta a while back and this was such a huge improvement to working in a terminal and having amazing syntax highlighting for diffs

Currently in ActiveJob, `wait` in `retry_on` accepts a proc, but it is only handed the execution count. I think access to the error can also be useful when calculating the next wait time. If you agree, give it a like! github.com/rails/rails/...
