Usage

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(unihan_options)

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.

Developing

poetry is a required package to develop.

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

cd cihai

poetry install -E "docs test coverage lint format"

Makefile commands prefixed with watch_ will watch files and rerun.

Tests

poetry run py.test

Helpers: make test Rerun tests on file change: make watch_test (requires entr(1))

Documentation

Default preview server: http://localhost:8035

cd docs/ and make html to build. make serve to start http server.

Helpers: make build_docs, make serve_docs

Rebuild docs on file change: make watch_docs (requires entr(1))

Rebuild docs and run server via one terminal: make dev_docs (requires above, and a make(1) with -J support, e.g. GNU Make)

Formatting / Linting

The project uses black and isort (one after the other) and runs flake8 via CI. See the configuration in pyproject.toml and setup.cfg:

make black isort: Run black first, then isort to handle import nuances make flake8, to watch (requires entr(1)): make watch_flake8

Releasing

As of 0.10, poetry handles virtualenv creation, package requirements, versioning, building, and publishing. Therefore there is no setup.py or requirements files.

Update __version__ in __about__.py and pyproject.toml:

git commit -m 'build(cihai): Tag v0.1.1'
git tag v0.1.1
git push
git push --tags
poetry build
poetry deploy
