Recently I use web app made with ruby.
The app is very useful for me, but there is not chemoinformatics library in ruby.
So, I want to find way to use rdkit from ruby.
I found some web page that described how to run shell script from ruby. The simplest way is using back quotation.
It is means call “python xxx.py” from ruby.
I tested it.
At first, I wrote sample script named test.py. Just load SDF and print molecules as smiles.
from rdkit import Chem
sdf = Chem.SDMolSupplier( 'cdk2.sdf' )
for mol in sdf:
smi = Chem.MolToSmiles( mol )
print( smi )
Then, I wrote ruby script.
It just call test.py. That’s all. 😉
callpy.rb
res = `python test.py` print res
Run callpy.rb.

It worked. 😉
There are some ways to call shell script from ruby. I will try another method soon.
