Enjoying myself as I go through Learn Go with Tests by Chris James.
I didn’t enjoy myself on the official tour, or with whatever LinkedIn course it was that I took. The structure and flow of the learn-by-testing piece gives me a familiar context and the pace seems just about right. It’s giving me ideas where I might enjoy Go for my own projects.
So yeah I like it.
Still having some tiny issues with the output of
Part of it’s that my brain hasn’t gotten used to how Go displays its errors. Some of it’s that my brain always has — and always will — panic at random symbols without context.
I figured I wasn’t the first with this problem, so I went looking. Found a Stack Overflow answer pointing
me to grc. Installed via Homebrew, then followed directions from Stack Overflow to configure grc, with
a slight tweak to
grc needs an entry in
~/.grc/grc.conf for Go test runs.
# Go \bgo.* test\b conf.gotest
I did make a slight tweak to the suggested
~/.grc/conf.gotest, so that “panic” lines get highlighted as failures.
regexp==== RUN .* colour=blue - regexp=--- PASS: .* colour=green - regexp=^PASS$ colour=green - regexp=^(ok|\?) .* colour=magenta - regexp=^\s*panic: .* colour=red - regexp=--- FAIL: .* colour=red - regexp=[^\s]+\.go(:\d+)? colour=cyan
Now when I run tests through
grc go test, output is colorized and I can track it more easily!
Of course I’ll probably get used to how Go presents errors and then forget all about grc, but it’s great for today. Might be more generally useful too, if I want colorized output that my tools don’t already provide!
