- Many, many updates to the public header files.
- tidyenum.h was reorganized substantially in order to better generate
documentation with Doxygen.
- This was also a good time to clean up all of the various enums for languages
and strings. Everything is simple and in a single enum now, other than a
couple of cases (TidyOptionId, for example, doesn't need to be redefined).
- A full and complete audit of the strings meant some opportunities to delete
useless strings.
- Reorganized the order of the strings in language_en.h in order to better
find things when programmers want to make changes. There are a lot fewer
internal "sections" now, and everything has been painstakingly sorted within
the remaining sections.
- Consequently rebased all of the PO's, POT, and other language files.
- Updated several of the READMEs with the newest information.
- Made the READMEs easier to copy into the Doxygen project by changing some of
the code format for compatibility, mainly the use of tildes instead of
backslashes for code blocks.
- Added tidyGetMessageCode() to message API. Despite the huge diff, this is the
only externally-visible change, other than removing some enums (but not their
values!).
- Passing `next` tests on Mac, Linux, Win10.
This is a rather large refactoring of Tidy's messaging system. This was done
mostly to allow non-C libraries that cannot adequately take advantage of
arg_lists a chance to query report filter information for information related
to arguments used in constructing an error message.
Three main goals were in mind for this project:
- Don't change the contents of Tidy's existing output sinks. This will ensure
that changes do no affect console Tidy users, or LibTidy users who use the
output sinks directly. This was accomplished 100% other than some improved
cosmetics in the output. See tidy-html5-tests repository, the `refactor` and
`more_messages_changes` branches for these minor diffs.
- Provide an API that is simple and also extensible without having to write new
error filters all the time. This was accomplished by adding the new message
callback `TidyMessageCallback` that provides callback functions an opaque
object representing the message, and an API to query the message for wanted
details. With this, we should never have to add a new callback routine again,
as additional API can simply be written against the opaque object.
- The API should work the same as the rest of LibTidy's API in that it's
consistent and only uses simple types with wide interoperability with other
languages. Thanks to @gagern who suggested the model for the API in #409.
Although the API uses the "Tidy" way off accessing data via an iterator
rather than an index, this can be easily abstracted in the target language.
There are two *major* API breaking changes:
- Removed TidyReportFilter2
- This was only used by one application in the entire world, and was a hacky
kludge that served its purpose. TidyReportCallback (né TidyReportFilter3)
is much better. If, for some reason, this affects you, I recommend using
TidyReportCallback instead. It's a minor change for your application.
- Renamed TidyReportFilter3 to TidyReportCallback
- This name is much more semantic, and much more sensible in light of
improved callback system. As the name implies, it remains capable of
*only* receiving callbacks for Tidy "reports."
Introducing TidyMessageCallback, and a new message interrogation API.
- As its name implies, it is able to capture (and optionally suppress) *all*
of Tidy's output, including the dialogue messages that never make it to
the existing report filters.
- Provides an opaque `TidyMessage` and an API that can be used to query against
it to find the juicy goodness inside.
- For example, `tidyGetMessageOutput( tmessage )` will return the complete,
localized message.
- Another example, `tidyGetMessageLine( tmessage )` will return the line the
message applies to.
- You can also get information about the individual arguments that make up a
message. By using the `tidyGetMessageArguments( tmessage )` itorator and
`tidyGetNextMessageArgument` you will obtain an opaque `TidyMessageArgument`
which has its own interrogation API. For example:
- tidyGetArgType( tmessage, &iterator );
- tidyGetArgFormat( tmessage, &iterator );
- tidyGetArgValueString( tmessage, &iterator );
- …and so on.
Other major changes include refactoring `messages.c` to use the new message
"object" directly when emitting messages to the console or output sinks. This
allowed replacement of a lot of specialized functions with generalized ones.
Some of this generalizing involved modifications to the `language_xx.h` header
files, and these are all positive improvements even without the above changes.
