Over the last week or two I had a go at writing this and called it pynd (python find). As a very young project it is likely to change and evolve but I would love some feedback. Is this something you think you would use? What features would you like to see? Please send me your feedback.
I have spent lots of time grepping huge Python projects, pynd is starting to make that easier for me.
What can it do?
Find and list all public functions
$ pynd --def --public ./retrace.py 181:def retry(*dargs, **dkwargs): 105: def delay(self, attempt_number): 117: def delay(self, attempt_number): 128: def attempt(self, attempt): 140: def attempt(self, attempt_number): 150: def validate(self, result): 159: def validate(self, result): 171: def delay(self, attempt_number): 174: def attempt(self, attempt_number): 177: def validate(self, result):
or, with the --private flag.
$ pynd --private --def ./retrace.py 49: def _update_wrapper(wrapper, wrapped, 67: def _wraps(wrapped, assigned=functools.WRAPPER_ASSIGNMENTS, 233: def _setup_limit(self, limit): 248: def _setup_interval(self, interval): 263: def _setup_validator(self, validator): 276: def _nice_name(self, thing):
Look for each time a class instance was created
$ pynd --class Interval --call ./retrace.py 100:class Interval(_BaseAction): 251: self._interval = Interval()
Search only within docstrings
$ pynd --doc "decorator" --ignore-case ./retrace.py 181:def retry(*dargs, **dkwargs): The retry decorator. Can be passed all the arguments that are accepted by Retry.__init__. 210:class Retry(object): The Retry decorator class. This class handles the retry process, calling wither limiters or interval objects which control the retry flow.
$ pynd --help usage: pynd [-h] [--version] [--ignore-dir [IGNORE_DIR [IGNORE_DIR ...]]] [--ignore-case] [--files-with-matches] [--show-stats] [--public | --private] [--verbose | --debug] [-d] [-c] [-f] [-i] [-C] [-a] [PATTERN] [FILES OR DIRECTORIES [FILES OR DIRECTORIES ...]] Search for PATTERN in each Python file in filesystem from the current directory down. If any files or directories are specified then only those are checked. positional arguments: PATTERN The pattern to match against. This must be a valid Python regular expression. FILES OR DIRECTORIES A file or directory to limit the search scope. This can be provided multiple times. optional arguments: -h, --help show this help message and exit --version show program's version number and exit --ignore-dir [IGNORE_DIR [IGNORE_DIR ...]] A pattern to exclude directories. This must be a valid Python regular expression. It can be provided multiple times. --ignore-case Make all the regular expression matching case insesitive. --files-with-matches Don't output all the results, just the paths to files that contain a result. --show-stats At the end, show some stats. --public Only show results considered to be public in Python. They don't start with an underscore. --private Only show results considered to be private in Python. They start with an underscore. --verbose Explain what is happening. --debug Output excessively to make debugging easier -d, --doc Match class and function docstrings. -c, --class Match class names. -f, --def Match function names. -i, --import Match imported package names. -C, --call Match call statements. -a, --attr Match attributes on objects
That was just a super quick tour of some of the features. Now I just need to settle in and use the project for a while and hopefully find a few others to do the same. Then we can see what to do next.
