Refining ModuleNotFoundError

[ehmatthes]

Polish this, and then start working on other exceptions.

• Write an e2e test.
• Run on Linux.
• Run on Windows.
• Update README to try out on Pillow?
• Update README to install from PyPI.
• Should modify only one import statement. Running against Pillow/src/PIL modifies all three plain import statements.
  • failing test (test file with two imports, should change only one)
  • pass the test
• Find all target elements, and choose one at random to modify.
• Implement a --num-bugs to introduce.
  • failing test
  • pass the test
• Consider implementing CLI with click; it's likely to grow larger than I want to manage with stdlib.
• Parse all .py files not in .gitignore.
• Start a utils/ dir, and a set of utils functions.
• Target random .py files, not just first one found. (Target random .py files, not first one found #14)
• Support --target-file.
• Try supporting -e IndexError?
• Make a 0.2 release, share.
• Make a 541 request? opened 3/25/25
• Move cli files to a separate cli/ dir, with a utils file.
• Move CST classes to a separate module.
• add_typo(name) - Add a typo to a legal python identifier.
  • Remove a char (if len(name) > 1)
  • Add a char
  • Replace a char
  • Add an illegal symbol
  • Replace _ with -.
  • But, make sure the intended exception is induced. ie, don't add a hyphen if that becomes a syntax error. (Maybe check the args, and if SyntaxError not in args, don't make that kind of change.)
• Keep a clean main file.
  • Move most logic to other modules and subdirs.
• Finish logic for simple imports.
  • Find all imports before choosing which to modify.
  • Add an arg for modifying more than one. (post 1.0)
  • Maybe parse all nodes before focusing on specific modifications.
• Manage git.
  • Make sure .git dir.
  • Make sure clean commit.
  • Make a commit after modifying files.
• Make an initial release.
• Share this, for early feedback.
  • Call out silly SO post.

More notes

• Uninstall a package that's imported?
• Make a better system for tracking which changes to make, and which have been made.

Workflow

• For each bug requested, randomly choose a file, then randomly choose a node to create that kind of bug.
