"unknown command pkg" from raco pollen render

[soegaard]

I get the following error when I follow the example in the docs.
I can't figure out what went wrong.

mba-5:pollen-example soegaard$ cat hello-world.txt.pp

lang pollen

Goodbye Stranger
Breakfast in America
Take the Long Way Home

mba-5:pollen-example soegaard$ ~/racket-april-2014/racket/racket/bin/raco pollen render hello-world.txt.pp
unknown command pkg

More pieces for the puzzle below. The problem is not "render", but using pollen from raco.

mba-5:pollen-example soegaard$ ~/racket-april-2014/racket/racket/bin/raco pkg install pollen

I've seen this bug a couple times. It has something to do with inconsistent .zo files. I'll take a closer look.

[soegaard]

Thanks for the hint. If it is related to .zo files, then the problem must be on my end.
Maybe it is due to the memoize package?

See http://bugs.racket-lang.org/query/?cmd=view&pr=14473

I fixed the problem with memoize, but it didn't help:

This problem was triggered by pollen/raco getting precompiled during raco setup. If it is left uncompiled, the problem seems to be fixed. (Though the reasons for this will have to remain mysterious to me.) I have updated info.rkt accordingly.

[soegaard]

Odd indeed. Thanks for the explanation.

Actually, maybe it's not that mysterious.

When you do raco setup pollen, the compiler performs any macro expansion as part of making the bytecode files, meaning all macros happen at (pre)compile time.

Whereas my pollen/raco file, which handles the arguments that are passed to raco pollen, depends on macros that need to be evaluated at runtime. So precompiling this file defeats the intended behavior. (In fact, that's why you saw unknown command pkg, because "pkg" was the argument sitting in the command line when pollen/raco got precompiled during setup.)

Strictly speaking, I didn't need to do it this way. But the raco pollen start command invokes the Racket webserver, which takes a long time to load. So it's a lot snappier to move the argument parsing into the syntax layer so I can avoid loading unnecessary modules.

If pollen/raco is omitted from the precompiled source files, it has to be expanded at runtime. This is the right result.

[mbutterick]

And thanks for the bug report.
