Error on pych --compile

[buddha314]

I have two files.

call.py

from pych.extern import Chapel

@Chapel(sfile='./response.chpl')
def shout_out():
    return None

if __name__=="__main__":
    shout_out()

and response.chpl

module Response{
  export
  proc shout_out() {
        writeln("HI DEE HI DEE HI DEE HI!");
  }
}

They are next to each other in the same directory. I have sourced the SubGenius' venv.sh as in this ticket: #75

When I was least expecting it, I got attacked by an error log:

(pychapel) >  pych --compile response.chpl

I blame myself, really... But PyChapel may have a bug in it.

[lydia-duncan]

Yeah, that's definitely a limitation. It currently likes its sfiles to live in a separate directory with sfile in the path name

[buddha314]

Sounds like it more than "likes" it, sounds like it DEMANDS it... brat. Okay, is the solution to then do..?

src/python/call.py
src/chpl/sfile.response.chpl

[buddha314]

Computer says "No"

pych --compile chpl/sfile.response.chpl

I think you'll want

src/call.py
src/sfile/chpl/sfile.response.chpl

but I'm looking if that's just because I've been writing tests in $LydiasPychapelInstallDir/docs/source/examples/

[lydia-duncan]

Also, that error looks really similar to #15

[buddha314]

Computer says "No". What is this, the f'n HAL 9000? Open the pod-bay doors, damn it!

What is old is new again...

[lydia-duncan]

You know, I haven't tried pych --compile in a really long time. I tend to just python compile and blow away the .chpl file when I need to. Should probably have a test script that ran that guy when it worked (if it worked 3 years ago?)

[lydia-duncan]

You are finding so many things I forgot about!

[buddha314]

It changes the room when actual users walk in... I get the same thing every time we deploy to production, I hide under my desk.

[buddha314]

I moved the file to a sub directory. Here is my new call.py

import os
from pych.extern import Chapel

currentloc = os.path.dirname(os.path.realpath(__file__))

@Chapel(sfile=os.path.join(currentloc + '/sfile/chpl/sfile.response.chpl'))
def shout_out():
    return None

if __name__=="__main__":
    shout_out()

And then I skipped pych -c and went straight to python call.py. It worked! Now I'm going to try to modify the .chpl file and see what breaks next.

[buddha314]

Well, all right! I have new files. Using the two below, just running python call.py works. When I modify response.chpl the updated version gets executed. With this in mind, I don't know when I would need to compile them first with pych. I think for what I need, I'll just run with the python command.

Also running the first time is slow, second time much faster.

reponse.chpl

module Response{
  export
  proc shout_out() {
        writeln("HI DEE HI DEE HI DEE HI!");
        writeln("HO DEE HO DEE HO DEE HO!");
        writeln("YIPPIDITY DIPPITIY DEE DAAAA!");
  }
}

call.py

import os
from pych.extern import Chapel

currentloc = os.path.dirname(os.path.realpath(__file__))

# @Chapel(sfile=os.path.join(currentloc + '/sfile/chpl/sfile.response.chpl'))
@Chapel(sfile=os.path.join(currentloc + '/response.chpl'))
def shout_out():
    return None

if __name__=="__main__":
    shout_out()

[lydia-duncan]

Excellent! We should still fix the pych --compile command, but I'm glad you are able to make progress!
