Antlr import issue #2

Closed VaibhaviRaut closed 4 years ago

VaibhaviRaut commented 4 years ago

I followed the instructions in the swum_phrases -> readme and got the antlr4 installation correctly but am still not able to import the antlr library from lines 11 through 13. I tried referring to the website mentioned as well but I might have missed something?

Can you please guide me with the installations or are there any changes to be made?

Maybe a typo? Try replacing antlr-python3-runtime with antlr4-python3-runtime.

VaibhaviRaut commented 4 years ago

I was able to install antlr4 using this command 'antlr4-python3-runtime' but I'm not able to resolve this:

from antlr.SwumParser import SwumParser from antlr.SwumParserVisitor import SwumParserVisitor from antlr.SwumLexer import SwumLexer

I tried to run 'antlr-python3-runtime' for the above error but didn't work :P so I tried to check out the website mentioned in the readme which indicated these steps:

Quick Start See Getting Started with ANTLR v4OS X $ cd /usr/local/lib $ sudo curl -O https://www.antlr.org/download/antlr-4.8-complete.jar $ export CLASSPATH=".:/usr/local/lib/antlr-4.8-complete.jar:$CLASSPATH" $ alias antlr4='java -jar /usr/local/lib/antlr-4.8-complete.jar' $ alias grun='java org.antlr.v4.gui.TestRig'

I tried them, nothing really happened.

The imports from antlr are referring to the directory in the swum_phrases folder, so no need to install anything :)

Your IDE will complain about not being able to resolve the imports -- this is because when you run the swum_phrases script, the script first generates python files in the antlr directory before running SwumPhrases.py. Try the command . ./swum_phrases tests/testcases/simple_success.xml output.xml and see if it works.

Also if you haven't already, I would put the last three commands from the getting started page at the end of your ~/.bashrc file - this will save you from having to re-type them every time you open your terminal.

I tried running the cmd and below is the output, I'm not sure if it worked. Oh and my bad I forgot to mention but I'm using Pycharm IDE.

Also, should the ~/.bashrc file to be modified, be the external one through the system's terminal or through the Pycharm terminal? I tried doing both and tried to re-run the cmd you gave but still getting the same output.

I helped her fix it.

Thanks @BrianPopeck for helping Vaibhavi out.
