Just a reminder for myself on how to do certain things

Pytest

Printout all outputs (-s is important) pytest -s -k TestName

Datalad

https://github.com/jstout211/datalad_examples

Used for nested looping and getting the x,y index in a matrix

np.unravel_index(tile_idxs, [row_num, col_num])

find all files and replace a specific word (deprecated function) with an alternative. Use git clean / checkout / restore to fix if erroneous changes happen

find /MYGITPROJECT/ -type f | xargs sed -i 's/word1/word2/g'

Checking connectivity issues to a computer

ping IPADDRESS --- if this works and the below says filtered, then there is a network block
sudo nmap -p 22 -Pn --traceroute IPADDRESS

also nslookup is helpful to return the ip address of a named computer
On the local computer --- sudo ufw status -- this may show any local firewall filtering that is occuring

Upload to pypi

Register at pypi and testpypi
Get a token and add to ~/.pypirc

python3 -m build -> Generates the ./dist folder with wheel and tar.gz files Test Repo
twine upload --repository testpypi dist/* --verbose

Sphinx setup (still learning this)

pip install sphinx
pip install sphinxcontrib-napoleon

mkdir docs
cd docs
sphinx-quickstart

Add the following to the conf.py file :

import os, sys
sys.path.insert(0, os.path.abspath('..'))

extensions = ["sphinx.ext.todo", "sphinx.ext.viewcode", "sphinx.ext.autodoc", "sphinx.ext.napoleon"]  

Run

cd ..
sphinx-apidoc -o docs .
sphinx-build -b html ./ ./html
