mscz-differ

Compares two MuseScore files and colorizes notes that are different.

Usage

Consider having two similar .mscz files

• a.mscz
• b.mscz

Running ./mscz-differ.py a.mscz b.mscz creates two new files

• a-b.mscz
• b-a.mscz

a-b.mscz have exactly the same content as a.mscz with the only difference that the elements not found in b.mscz are color highlighted.

Usage Examples

• finding differences among two versions of the same project (as already written above)
• finding differences among two parts of the same file, e.g. when merging two consecutive verse sections into one repeated section
  • this requires to extract each verse section into own separate file before applying this differ

Current Limitations

• currently only Notes diff highlighting is implemented (no other elements like Rest differencing is present)
• tested on Linux only
• the cross-check between the two files is done naively in O(2*m*n)
