PIP Module Scanner
Scans your Python project for all installed third party pip libraries that are used and generates a requirements.txt based output.
Installation
Installing the scanner is easy, either clone the repository and run the script or install it via pip like so:
$ pip install pip-module-scannerUsage
Using the scanner is incredibly simple. Open a terminal and navigate to your project folder, run the script and watch magic happen before your eyes. Example:
$ cd ~/projects/my-awesome-project/
$ pip-module-scanner
foo==1.0.0
bar==2.1.0
baz==0.0.1Specifying a custom path
You can specify a custom path in which you want to run the script with the -p or --path argument. Example:
$ pip-module-scanner --path ~/projects/my-awesome-project/
foo==1.0.0
bar==2.1.0
baz==0.0.1Writing the output to a file
You can write the output of the script to a file by using the -o or --out argument. Example:
$ cd ~/projects/my-awesome-project/
$ pip-module-scanner -o requirements.txt
$ cat requirements.txt
foo==1.0.0
bar==2.1.0
baz==0.0.1Integrating the code in your project
You can easily integrate the scanner code in your own project so you can get the output of the scanner yourself or modify the class to suit your own needs. To do this, you can use it like so:
from pip_module_scanner.scanner import Scanner
scanner = Scanner()
scanner.run()
# do whatever you want with the results here
# example:
for lib in scanner.libraries_found:
print ("Found module %s at version %s" % (lib.key, lib.version))Specifying a path would work like so, make sure to also import the ScannerException as it will check if the path you specified is actually a real path:
from pip_module_scanner.scanner import Scanner, ScannerException
try:
scanner = Scanner(path="~/projects/my-awesome-project/")
scanner.run()
# do whatever you want with the results here
# example:
for lib in scanner.libraries_found:
print ("Found module %s at version %s" % (lib.key, lib.version))
except ScannerException as e:
print("Error: %s" % str(e))For the one-liner junkies out there (like me) you can also get all libraries with this nifty little one-liner (I'm so considerate)
from pip_module_scanner.scanner import Scanner
libs = Scanner().run().libraries_found # Isn't it beautiful?Class definitions
