====================================================== sgflib: Smart Game Format Parser Library & Utilities

Description

For Python programmers, sgflib.py is a module containing a parser and classes for SGF, the Smart Game Format, specifically for the game of Go.

For Go players, several utilities are included:

sgfmerge: Merge two or more game record files into one. Works best when the game record files are for the same game, and contain variations.
sgfnorm: Normalize an SGF file. Usful for comparing two files representing the same game.
sgfsummary: Read, analyze, and summarize one or more SGF files.

You'll need the Python language itself, version 3.8 or higher, freely available from http://www.python.org.

The sgflib.tgz archive contains the following:

If you have any trouble running this code, if you find (maybe fix?) any bugs, or add any features, please contact_ the author.

Reimplement the GameTree as a data structure that's convenient for the user of sgflib, rather than following the file format.
Reimplement the Cursor class? Or remove it altogether if unnecessary.
Reimplement the parser?
- Simplify. It works, but it seems clunky. Written early in my Python career.
- Reimplement as a generator?
- Support earlier versions of SGF?
Titler: Populate the title (GN/game_name property) inside the SGF file itself, e.g.:
```
player1 (2 dan, white) vs player2 (4 kyu, black +h5); W+18½; KGS; 2020-12-04
```

Renamer: Rename SGF files, e.g.:

2020-12-04 player1 · player2 +h5 W+18.sgf

Query SGF data: Extract game & node properties & comments from .sgf files. Queries could be Python expressions for maximum flexibility.
Handicap convertor? Lizzie (Leela Zero?) can't handle handicap stones, so this program would convert the HA[n] & AB[xx] tags to B[xx] moves & W[] passes. Katago via KaTrain doesn't have this problem though.
Auto-label variations.
