When I switched over to `flask run` entrypoint in b92391d177,
I forgot that the `if name==__main__` code no longer triggers.
So the SQLite in-memory database wasn't getting created for the example
app.
This moves the DB creation to a werkzeug/Flask hook that runs before the
first request to the app, so that the DB table is created when we query
it.
Also updated the test which worked fine previously, but this is more
idiomatic.
Drop `flask_script` in favor of Flask's native CLI:
* https://flask.palletsprojects.com/en/master/cli/
This also requires changing the tests so that `pytest` mocks the env var
`FLASK_ENV` so that the test app starts in development mode. Unlike
normal test apps, we _do_ want development/debug mode, in addition to
testing mode.
SQL queries containing non-ascii byte strings would cause errors, both with and
without Pygments highlighting.
This updates the non-Pygments case to handle a simple decoding to ensure the
value is ascii-safe. It also removes passing an explicit "utf-8" encoding to
Pygments, since this causes errors when the bytes are not utf-8. When the
encoding is omitted, Pygments will default to "guess" the encoding by trying
utf-8 and falling back to latin-1.
Fixes#55
The os.path.commonprefix() function only does basic string prefix checking, and
isn't aware of case-insensitive file names, or path separators. Instead, this
switches the filename formatting to use os.path.relpath() for normalizing paths
relative to sys.path.
Fixes#67
