output, classify and organize all of the dialogue type of messages. This paves
the way towards formalizing (and expanding!) the footnotes system with much
greater explanatory text, as well as providing much better fine-grained control
over which types of output that Tidy will produce.
Moved STRING_DOCTYPE_GIVEN, STRING_CONTENT_LOOKS, and STRING_NO_SYSID to the
Report paradigm from the Dialogue paradigm, as these are items that are
traditionally TidyInfo and included in the Report table, rather than any type
of dialogue.
At this point, we are exactly passing all tests.
Note that there are several regressions in the accessibility test suit that
are not related to output messages. These are a result of previous work, and
these results should be updated in the test suite when this item is merged.
extension is a file, and so links to TLD's ending with .pl, .au, etc., will
cause accessibility warnings. This fix attempts to distinguish between URI's
that are likely to be files versus links to domains.
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.
- Consolidated all output string definitions enums into `tidyenum.h`, which
is where they belong, and where they have proper visibility.
- Re-arranged `messages.c/h` with several comments useful to developers.
- Properly added the key lookup functions and the language localization
functions into tidy.h/tidylib.c with proper name-spacing.
- Previous point restored a *lot* of sanity to the #include pollution that's
been introduced in light of these.
- Note that opaque types have been (properly) introduced. Look at the updated
headers for `language.h`. In particular only an opaque structure is passed
outside of LibTidy, and so use TidyLangWindowsName and TidyLangPosixName
to poll these objects.
- Console application updated as a result of this.
- Removed dead code:
- void TY_(UnknownOption)( TidyDocImpl* doc, char c );
- void TY_(UnknownFile)( TidyDocImpl* doc, ctmbstr program, ctmbstr file );
- Redundant strings were removed with the removal of this dead code.
- Several enums were given fixed starting values. YOUR PROGRAMS SHOULD NEVER
depend on enum values. `TidyReportLevel` is an example of such.
- Some enums were removed as a result of this. `TidyReportLevel` now has
matching strings, so the redundant `TidyReportLevelStrings` was removed.
- All of the PO's and language header files were regenerated as a result of
the string cleanup and header cleanup.
- Made the interface to the library version and release date consistent.
- CMakeLists.txt now supports SUPPORT_CONSOLE_APP. The intention is to
be able to remove console-only code from LibTidy (for LibTidy users).
- Updated README/MESSAGES.md, which is *vastly* more simple now.
