Originally forked from oppai-chunks to use pyoppai for a massive speed boost. Now I've rewritten it to use pyttanko with strains instead of difficulty.
Runs on Python 3 and uses pyttanko
./osustrain.py beatmap [mod bitwise]
beatmap is the .osu file you want to analyze.
mod bitwise is the bitwise for the mod combination(s) you want to apply.
For example, ./osustrain.py "haitai.osu" 24 will provide the strains for the map with HDHR.
Output are each chunks strain values for speed and aim with the sum of the two.
from osustrain import get_strains
...
get_strains(beatmap, mods=24)
You can also graph the strains instead.
from osustrain import get_strains
...
graph(beatmap, mods=24)
The arguments are the same as above. Here, the beatmap should be given as a path (osustrain('/path/to/beatmap.osu')). The outputs are four lists for the seperate strains for speed, aim, the sum of the two, and the time in milliseconds of which the chunk starts.
