Very nice article!
Thank you!
Interesting from the animation that it decided that importing
std.stdio can be "reduced" to importing std!
Yes, it's a new minor annoyance for all DustMite users :)
I see that you can prevent reductions via regex.
Regex and similar rules are applied at input parsing time, not on
the emitted output.
How do you say "Don't reduce `std\..*` to `std`" or is that
possible? In other words, I'm fine with reducing imports, but
not that specific reduction.
The canonical way, right now, is to add something like `if grep
-q 'import .*std[;,]' ; then exit 1 ; fi` to the test script. To
make this test reusable, it can be saved to e.g.
"dustmite-no-std" and DustMite invoked with `dustmite src
"dustmite-no-std && ../actual-test-script.sh"`.
I don't know if it's worth it, but to make this common annoyance
easier to handle without baking in more highly-D-specific stuff
into a tool which aims to be general-purpose, I'm thinking of the
following additions:
1. Allow more than one test command. A reduction is considered
successful only if all test commands pass. (It would be the
equivalent of chaining them with && in a shell command.)
2. Add built-in tests which can be used in place of a test
command, such as ":d-no-std".
