Getting Help

QuickStart

#wget https://github.com/alex-ber/PythonPackageSyncTool/archive/master.zip -O master.zip; unzip master.zip; rm master.zip

pip3 install https://github.com/alex-ber/PythonPackageSyncTool/archive/master.zip#egg=python-package-sync-tool[tests]

---

python3 -m pip install https://github.com/alex-ber/PythonPackageSyncTool/archive/master.zip

cd /opt/anaconda3/lib/python3.7/site-packages/alexber/reqsync/data/

Note: This is Path where you’re actually install my utility, it can be different in your machine.

If you use venv it will look something like:

cd /opt/MyProject/venv/Lib/site-packages/alexber/reqsync

---

Alternatively you can create these file for yourself, named driver.py:

#!/usr/bin/python3

import alexber.reqsync.app as app

if __name__ == “__main__”:

app.main()

Than create file config.yml near your script (see data/config.yml) or provide all parameter using command line argruments. Use ‘:’ in places where you should naturally write ‘==’ (see explanation below).

Parammeters ‘source’ and ‘destination’ are required. You should also provide (requirements) file for ‘source’.

‘mutual_exclusion’ has default value True.

---

After you’ll go to the directory with driver script (whether provided or that you’ve just written). Type

Note: I’m assuming hear that you have config.yml as in data/config.yml.

chmod 755 driver.py

./driver.py –add=some_new_package:1.0.0

This will add some_new_package with version 1.0.0 to the requirements-dest.txt

Note:

Semicolomn and not equal sign is used here due to Python limitaion of usage of equal sign in the value in the command line.

You can specified multiple packages using comma delimiter.

You can specifiy path to your config file using –config_file.

It can be relative to the folder whether you put driver.py script or absolute.

---

./driver.py –add=some_new_package

This will run quick check whether package is not in remove list.

Installing from source

python3 -m pip install . # only installs “required”

python3 -m pip install .[test] # installs dependencies for tests

---

From the directory with setup.py

python3 setup.py test #run all tests

pytest
