Modify the build system to assume config files by default. Modify tidyplatform
to accomodate these changes. Reformat tidyplatform for friendliness to new
developers.
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.
merge.
- Sort all of the existing options and re-indent per Tidy standards. This is
simply for cosmetic effect.
- Allow the iterator to return all options again, even "internal" options.
Things are too embedded with N_TIDY_OPTIONS, etc., to try to hide them.
- Instead, simply add documentation to LibTidy users that they shouldn't use
internal options.
- Also added `TidyInternalCategory` to `TidyConfigCategory` without adding a
new field to the struct. API users should check for this category before
use.
- Defined a two character macro for `TidyInternalCategory` for use in
`option_defs[]`.
- Changed struct `option_defs[]` to reflect the new category for affected
options.
- Removed string indicating * refers to internal options, since it no longer
applies.
- Regen'd all strings for previous point.
- `tidy.c` now checks for `TidyInternalCategory` everywhere in order to
suppress output.
- Updated strings files to match.
- Inhibit internal options from being output via the iterator. Internals should
never have the chance to be exposed if they shouldn't be use.
- Added tidySetEmacsFile() and TidyGetEmacsFile() to the public API, and use it
instead of secret API to set the filename in the console application.
The end result is that `gnu-emacs-file` (and also `doctype-mode`) officially no
longer exist to CLI users nor to API users, and tidy console behaves properly
by using a published API to set the filename for emacs.
- TidySlideStyle
- TidyBurstSlides
- Added documentation for TidyEmacsFile, since it's a valid option.
- Because TidyEmacsFile is a valid option, tweaked tidy.c so that it can
be specified in a configuration file without being overwritten by the console
app. Why a user might do this is dumb, but who are we to stop them.
- 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.
- Show the language Tidy is using.
- Update the POT and POs with the modified string.
- Regen language_es.h, which uses the string.
Note that the new header uses the new commentless behavior that's still
pending in another branch. In addition the proper c style hints have
been added to all PO's, as their previous absense was a bug.
In K&R (pure) C all variables used in a context must be declared before
the first executable phrase. gcc allowed this C/C++ crossover many years
ago.
But compilers, like MSVC, will bark at this problems with a quite weird
difficult to understand, error message!
This small re-arrangement of the code fixes that...
