Python

Hi,

I wanted to use d2 in an environment where I could only install python and npm packages.

Given that, and that I could not find any other solution, I made d2-python-wrapper, a small python wrapper that bundles the d2 binaries.

Now you can use d2 from python like this:

from d2_python import D2

d2 = D2()

# Simple diagram
with open("test.d2", "w") as f:
    f.write("x -> y")

# Default SVG output
d2.render("test.d2", "output.svg")

# PDF output with specific theme
d2.render("test.d2", "output.pdf", format="pdf", theme="1")

The class just wraps the bin, so it works and supports the same as the bin. There is a GitHub Action that gets the bins for each platform (mac, win, linux) from the releases in this repo and publishes it to pip.

You can install this using

pip install d2-python-wrapper

Here is a short post with more context.

Just in case It's useful for anyone. 😁

I store my programs in a cryptomator vault which uses a fuse virtual drive (The default on Linux), but when trying to update pip inside a venv I get an error, then any subsequent use of pip also throws an error and {path_to_venv}/lib/python3.12/site-packages/pip/ becomes empty.

I imagine this is an issue that would happen in any FUSE drive although I don't know how to test that.

Here are the logs

• OS : Fedora 40
• pip version: 23.3.2 updating to 24.2
• python version: 3.12.7

I already made a bug report on the github

Does anyone know a temporary workaround for this ?

So, this uses a macro, but if you're thinking anything is possible with a macro, it's actually not in Rust. The input does still need to parse as valid Rust tokens.

Which means the authors asked themselves at some point: Is the Rust syntax a superset of the Python syntax?
And well, it's not. In particular, some Python keywords will just be tokenized as an identifier (like a variable name).

But it is close enough that the authors decided against requiring a massive string to be passed in, which does amuse me. 🙃

Hi,

I use gunicorn in my venv

I have quite few venv that run gunicorn.

I would like to reuse gunicorn for other venv

I launch my web application like this

#PWD = venv dir
source ./bin/activate
gunicorn A_WebApp:app
#A_WebApp is my python file A_WebApp.py

I supposes that gunicorn is a shell program ? if yes I should use $PATH ?
or gunicorn is a Python program only ? and then what I should do to use gunicorn in another venv ?

Thanks.

Hi,

I'm looking for a software similar to ZoneMinder
https://lemmy.ml/post/18530232

But it seem that ZoneMinder become slowly outdated, php etc..

I've found a couples of alternatives ( hard choice as the limitations of use are often buried deep )

It seem that openCV is really famous for AI Computer vision, So I would be surprise if there were no Python program to manage cameras like a ZoneMinder !?

Do you know any ?

Thanks.

I'm just trying to control my smartlights with a script, it seems to be having a lot of problems, I really don't know what I'm doing, i'd appreciate any help I can get

Once I have a script that can individually turn lights on/off i can edit the rest myself, I just can't get the base functionality working.

Hey, I've been looking to learn Python for a while, tried as a kid but got bored before I did anything. I was wondering if anyone knew of any good Python self-study workbooks? The ones with exercises in addition to theory. I'm using Mint, in case that brings up any IDE issues.

Developed a script to perform mm to inches conversions, which was conveniently transformed into a web app using Streamlit.

Hello Python community! There are a lot of resources online targeted at beginners that want to learn Python but very rarely do you see articles talking about moving to Python when you already have tons of experience in other languages like Ruby, and especially, many years of Perl experience and is interested in moving to Python.

I'm not looking for information on how to program in Python, that's really easy to find and most of the learning curve will be learning about the standard libraries and overcoming the years of muscle memory from other languages. I'm looking for information on the following topics:

• What's the recommended project structure for a library or a program that'll be distributed via PyPI?
• What are the general best practices to follow when writing "clean Python code"?
• What's the most commonly followed style guide for the language?
• How does import work internally and how does it perform its path lookup for local files (specifically for importing modules internal to a project)?
• How to properly set up pyenv for a project? (This one is tricky for me because the Python community loves pyenv and I'm used to having packages globally installed in Ruby and Perl)
