Without this patch, parse-commit will unconditionally use a faillure
continuation which simply returns `#f`. This may be undesirable in
some situations. As such, this commit allows (optionally) passing
a custom failure continuation as a second argument. If none is passed
the old behavior is used, hence this commit doesn't cause any backwards
incompatible API changes.
See #822
While testing a `(chibi parser)`-based parser I noticed that
`parse-string` is the only provided parser combinator which uses a list,
instead of a string, as a failure reason. It is not explicitly
documented but since all other standard parser combinator use a string
for the error reason I assume this to be a bug and have adjusted the
`parse-string` combinator accordingly in this commit.
In `servlet-respond', the server defaults to Content-Type "text/html;
charset=UTF-8" for extensions that don't appear in
`mime-type-from-extension'. This meant that CSS files, JavaScript
files, and various types of image files were getting the wrong
Content-Type, which was fine when they were served directly, but
caused clients to close the connection when they were loaded over
HTTP/1.1, which can deliver back-to-back resources on the same
connection.
Sort the types in the `mime-type-from-extension' list now that it is
longer. It's still not long enough for the order to be material for
performance.
This restores third-party (ab)users of the Chibi macro system such
as in https://gist.github.com/baguette/2632464, while allowing us
to break those uses in more interesting ways.
It also keeps the core slightly smaller (both in C and Scheme)
and speeds up the macro expansion process.
Add some newlines and a comment to improve readability.
Use local string port instead of parameterizing current-output-port.
Pass symbol 'BEGIN to tell test reporter that evaluation of a test
starts. Adapt documentation of current-test-reporter accordingly.
Use define-opt instead of case-lambda.
