They are Python libraries that I developped on 2011.
- PyExecJS: Automatically picks the best runtime available to evaluate your JavaScript program.
- Python-CoffeeScript: A bridge to the JS CoffeeScript compiler.
They are ports of ruby gems with same name (execjs and ruby-coffee-script).
The aim of them were to compile CoffeeScript code on Windows XP. It was difficult and tangled to install Ruby, NodeJS or V8 (at least, I thought so). What I could use were builtin JScript and Python (which is installed with installer).
EOL. PyExecJS and Python-CoffeeScript are no longer maintananced. Bugs are not be fixed (even if they are trivial or essential).
We suggest to use other library or to make a fork.
Currently, NodeJS works on Windows 10.
- To execute JavaScript snippet, We can use
subprocess.check_output(['node', ...])
. - To compile CoffeeScript code, we can use build tool such as WebPacker.
So, I think that PyExecJS and Python-CoffeeScript are useless (for my original purpose).
It seems for me that PyExecJS is mainly used as a bridge to NodeJS.
However, As a bridge to NodeJS, PyExecJS is badly designed.
It is because I designed (cloned) PyExecJS as a adapter to cover-up difference of JS engines (NodeJS, PyV8, JScript, etc..).
So, PyExecJS does not support NodeJS specific features (such as to specify NODE_ENV
). It is difficult to add features while keeping consistency with original design.
If we want to call NodeJS function from Python, I think we should use raw subprocess.check_output
or an single purpose library.
Thanks for using PyExecJS and Python-CoffeeScript, for sending merge requests and issues.
hi can you make library to make possible compile coffee from python? that exactly what im looking for, but you said it no longer maintained
