Quickstart¶

API / Library (this repository)¶

$ pip install --user cihai

from cihai.core import Cihai

c = Cihai()

if not c.unihan.is_bootstrapped:  # download and install Unihan to db
    c.unihan.bootstrap()

query = c.unihan.lookup_char('好')
glyph = query.first()
print("lookup for 好: %s" % glyph.kDefinition)
# lookup for 好: good, excellent, fine; well

query = c.unihan.reverse_char('good')
print('matches for "good": %s ' % ', '.join([glph.char for glph in query]))
# matches for "good": 㑘, 㑤, 㓛, 㘬, 㙉, 㚃, 㚒, 㚥, 㛦, 㜴, 㜺, 㝖, 㤛, 㦝, ...

UNIHAN data¶

All datasets that cihai uses have stand-alone tools to export their data. No library required.

unihan-etl - UNIHAN data exports for csv, yaml and json.

Developing¶

$ git clone https://github.com/cihai/cihai.git`

$ cd cihai/

Bootstrap your environment and learn more about contributing. We use the same conventions / tools across all cihai projects: pytest, sphinx, mypy, ruff, tmuxp, and file watcher helpers (e.g. entr(1)).
