Error: invalid module name: 'nim_1.1.1'

when i use nim c nim_1.1.1, the error is:

Error: invalid module name: 'nim_1.1'

i think this maybe an error of naming the nim source file, or the compiler's fault

The compiler tells you 'nim_1.1' is not a valid module name. A module name in Nim must be valid Nim identifier. Nim identifiers cannot have dots in them.

And it turned out, I can't have a program name 01.nim, even if I'm not going to consider it a module. C can, Python can, J can, Nim can't. Very sad.

Araq (orginal) [2017-12-01T12:30:10+01:00] view original

The language considers it a module if you personally don't. You can name it e01.nim or -- even better -- anything else that actually has a meaning. The only sad thing here is your way of naming things.

geo555 (orginal) [2017-12-01T13:02:01+01:00] view original

You can't know. In AoC they've always been DD.c, DD.py, DD.dat, DD.txt, DD.ijs etc, just because DD means the day of month, no need to add more letters. Now this scheme has to be broken. Not a big deal, just an awkward unnecessary nuisance.

Is this a naming scheme suggested by AoC? day1, day2, etc. Is far better anyway IMO

geo555: I don't see how this is unexpected - Nearly all languages that have a "namespace" or "module" concept restrict namespace/module names to valid identifiers. This is so the module can be referenced within the code.

Python allows running scripts with invalid identifiers, however it doesn't allow importing modules with invalid identifiers without import trickery. I believe Ruby also has a similar restriction.

C++ requires namespaces to be valid identifiers.

Java requires packages to be valid identifiers.

C and C++ both allow for including files with arbitrary names, however that is because the inclusion is handled by the preprocessor - there is no way to use the name of an included file in the same way you would use a module name.

Never mind. The fix is really simple, a line in lexer.c, a couple of lines in cgen.c.

You can always use the switch --out:

-o:FILE, --out:FILE	set the output filename

geo555 (orginal) [2017-12-28T21:05:52+01:00] view original

You can always use the switch --out:

No, I can't! It has nothing to do with the input file name!

jibal (orginal) [2017-12-30T06:23:21+01:00] view original

No, I can't! It has nothing to do with the input file name!

You mean that it has nothing to do with the output file name, surely. I don't know why Arrrrrrrrr would think his suggestion was relevant.
