I don't find it convincing to see use cases that are already done with other tools. Making big changes to a tool that's worked well for years in order to duplicate existing functionality isn't IMO a good strategy. The good news for you is that you don't need to convince me. I'm not the one that makes these decisions. Whether I agree or disagree is of no consequence.

I testet (dub master) the isUpToDate behavior on windows, linux (shebang and no shebang),
with source code files having *.d extension and without.

isUpToDate is always working fine and uses the last build.

I'm trying: https://github.com/Homebrew/homebrew-core/pull/47501 but apparently formulas recommend github repos with X stars and Y forks. So there's a chance it may be rejected. Let's see! 🤞

Looks like they require > 30 forks, > 30 watchers and > 75 stars. A reasonable requirement. rund has 1 fork, 2 watchers and 21 stars, so we'll have to wait and see if it gets more popular.

To everyone, if you want to see rund in your package manager of choice, show your support by starring and/or watching it on github: https://github.com/dragon-lang/rund

Added my own tap if anyone wants it on osx+brew.

brew install aliak00/dtap/rund

or

Or brew tap aliak00/dtap and then brew install rund

Here the fix which avoids the rebuild of Single file packages https://github.com/dlang/dub/pull/1811

Dub is a very good piece of software and issues can in most cases easily be fixed.

Nice work!

running a script with a single dependency, average of 3 runs.

currently:

Time           : 4224 ms (1408.000 ms/per)
Max RSS        : 313.6 MB

and with your pull request:

Time           : 398 ms (132.667 ms/per)
Max RSS        : 29.0 MB

Although...

Time           : 24 ms (8.000 ms/per)
Max RSS        : 5.0 MB

This is the time I get from directly calling the binary that
dub leaves under /tmp

So that's still quite a lot of overhead.

What is the overhead of dub, if you do not count the first run?
(the first run compiles the script to an executable, each sub subsequent
run from now on just calls the executable)

Did you compile dub using dmd or ldc? Performance of LDC with optimizations
on is a lot better than debug builds of dmd.

Kind regards
