08/20/2015, 6:30 PMtoday PythonTask uses the global PythonSetup but it doesn't have to - m

08/20/2015, 6:31 PMso currently if someone wants to specify that they want to use ipython or some other interpreter on the command line they have to do… ./pants repl.py --ipython target I’m proposing that we allow ./pants repl —interpreter python|ipython for any other langs that have alternative interpreters they could use the same flag. - m

08/20/2015, 6:32 PM@rough-minister-58256 I don’t believe we would need to bundle ipython, unless that is already bundled since you can currently use ipython as the interpreter… its just awkard. - r

08/20/2015, 6:45 PMwhy not just./pants repl.ipy - b

08/20/2015, 6:53 PMI think I'm with molsen here. - b

08/20/2015, 6:53 PMYou can also imagine wanting
orjython
(or whatever) as your interpreter to test something on a replpypy - b

08/20/2015, 6:54 PMThere's a more generic issue here of asking repl or another python task to use a specific interpreter - a

08/20/2015, 6:54 PM@bored-art-40741: Yes. I sat around and did nothing and Nick and Fedor came along and started implementing stuff - b

08/20/2015, 6:54 PMOh cool - b
bored-art-40741
08/20/2015, 6:54 PMI missed those CRs - h
happy-kitchen-89482
08/20/2015, 6:55 PMA note on terminology: my understanding (and I could be wrong) is that ipython is a fancy shell, not an independent interpreter. - a

08/20/2015, 6:55 PMThis is why it is good to write design docs. - a

08/20/2015, 6:55 PMI don’t think Nick’s has landed yet. - h
happy-kitchen-89482
08/20/2015, 6:55 PMI.e., it doesn't implement a bytecode interpreter itself - h
happy-kitchen-89482
08/20/2015, 6:55 PMis that the case? - m
mammoth-pharmacist-54215
08/20/2015, 6:55 PM@rough-minister-58256: repl.ipy is not exactly clean… really people want to run repl they just want to override the interpreter… in their mind its not a separate task/goal, its just an option. - m

08/20/2015, 6:56 PM@bored-art-40741: I agree, this is a more general problem… just trying to solve this piece of it atm, since it’s the one I’ve heard people bring up. - h
happy-kitchen-89482
08/20/2015, 6:57 PMEither way, I would rather be very clear with the terminology - in Pants an 'interpreter' is a thing that compiles python source to bytecode and interprets that bytecode. What you're talking about is how to choose an interactive shell, yes? - h
happy-kitchen-89482
08/20/2015, 6:57 PMThose aren't the same. - r
rough-minister-58256
08/20/2015, 6:57 PMI think I’d much rather type
than./pants repl.ipy ...
just due to the shorthand../pants repl —interpreter=ipython … - b
bored-art-40741
08/20/2015, 6:57 PMWell, the latter wouldn't work - b
bored-art-40741
08/20/2015, 6:57 PMThe option is fully scoped - b
bored-art-40741
08/20/2015, 6:58 PMAnd if you set this with an environment variable or in pants.ini, then you don't need to type the option - m
mammoth-pharmacist-54215
08/20/2015, 7:03 PMthe problem (at twitter) with telling people to change things in pants.ini is most people use command line options to override things that we provide a pants.ini for them already with a bunch of settings. Command line options provide users a good way to override things on an individual basis. - m

08/20/2015, 7:03 PM@bored-art-40741: I don’t understand why you are saying ./pants repl —interpreter=ipython wouldn’t’ work? - b
bored-art-40741
08/20/2015, 7:04 PMIt would need to berepl.python - b
bored-art-40741
08/20/2015, 7:04 PMBecause of scoping - b
bored-art-40741
08/20/2015, 7:04 PMOr./pants repl --repl-python-interpreter=... - b
bored-art-40741
08/20/2015, 7:04 PMIt's a minor point
