From 1.4.6 to 2.0
|
|
---------------------------
|
|
(25.06.2004)
|
|
|
|
Added support for XML 1.1 (Entities.getChar, UniClasses.isNms/isName/isXml
|
|
have now an 11 (for 1.1) counterpart which are to be called when the XML
|
|
declaration declares version 1.1.
|
|
|
|
Changed Makefile to better support Windows installation.
|
|
|
|
(13.02.2004)
|
|
Updated fxp to handle the new specification of the xml:space attribute
|
|
|
|
From 1.4.5 to 1.4.6
|
|
---------------------------
|
|
(09.10.2003)
|
|
Modified documentation to fit in the fxgrep gui framework
|
|
|
|
From 1.4.4 to 1.4.5
|
|
---------------------------
|
|
(20.02.2002)
|
|
Modified the Makefiles to avoid unnecessary recompilations
|
|
2001-09-17
|
|
- added hasElement, hasAttribute, etc. functions in Dtd
|
|
|
|
Changes from 1.4.3 to 1.4.4
|
|
---------------------------
|
|
2000-10-30
|
|
- fixed a bug : parser reported an error if more than one definition
|
|
was provided for the same ID attribute, instead of ignoring
|
|
delarations later than the first one
|
|
|
|
Changes from 1.4.2 to 1.4.3
|
|
---------------------------
|
|
2000-08-29:
|
|
- modified the autodetection of character encodings as stated in the
|
|
XML 1.0 Specification Errata from 2000-08-10 under E 44; among
|
|
others, UTF-8 with BOM is now recognized.
|
|
|
|
Changes from 1.4.1 to 1.4.2:
|
|
--------------------------
|
|
2000-07-28:
|
|
- fixed a Solaris bug in the Makefile
|
|
|
|
Changes from 1.4 to 1.4.1:
|
|
--------------------------
|
|
2000-06-08:
|
|
- fixed a bug in surrogate composition
|
|
- fixed a bug: parser complained about undeclared entities in
|
|
non-validating mode, even if the DTD has paramter references.
|
|
- fixed another bug: parser never complained about undeclared
|
|
parameter entities that constitute a validity error.
|
|
- slightly restructured ParseRefs; resulting in some minor
|
|
changes in other modules.
|
|
- modified sample applications to report fatal errors as fatal.
|
|
|
|
Changes from 1.3 to 1.4:
|
|
------------------------
|
|
2000-02-18:
|
|
- fixed a bug in UtilCompare.compareVector
|
|
- eliminated UnsafeOps structure. Unsafe operations yield only
|
|
insignificant speedup, but extremely impair reliability.
|
|
|
|
2000-02-10:
|
|
- parseElementContent reports only a single error for each piece
|
|
of character data in element content. Before this change, it did
|
|
report an error after each sequence of white space characters
|
|
followed by non-white space. Similarly for parseDocument.
|
|
|
|
1999-10-22:
|
|
- Added the start position of the PI text to HookData.ProcInstInfo.
|
|
|
|
1999-10-18:
|
|
- Fixed a small bug in UtilHash.hashTriple
|
|
|
|
1999-08-27:
|
|
- Removed the this/next components from the Entities.State type.
|
|
It is sufficient to compare the entity's indices in the DTD.
|
|
Added a type EntId, indicating whether an entity is a parameter
|
|
or general entity, and holding its index. isOpen, pushIntern and
|
|
pushExtern now have an additional parameter isParam:bool. Changed
|
|
all parser functions accordingly.
|
|
|
|
Changes from 1.2 to 1.3:
|
|
------------------------
|
|
1999-08-24:
|
|
- Removed options --table-size/width.
|
|
- added new encoding UCS2B/L, which is UTF16 without surrogate pairs.
|
|
- unrolled the getBytes loop in getCharUtf8. UTF-8 does not recognize
|
|
surrogates pairs any more (cf. Rfc 2279, lines 201-206). The same
|
|
for UCS-4.
|
|
- changed implementation getCharUtf16/getCharUcs4: they are not higher
|
|
order any more. Efficiency increased.
|
|
|
|
1999-08-13:
|
|
- Changed ParseDecl.parseGenEntDecl not to check for declaredness of
|
|
unparsed entities' notations.
|
|
- Added maxUsedGen to Dtd: returns the number of general entities defined.
|
|
- Added checkUnparsed to DtdDeclare. It checks whether all notations of
|
|
unparsed entities have been declared. Added a call to checkUnparsed
|
|
at the end of parseDtd.
|
|
|
|
1999-08-12:
|
|
- Made DecodeUtf8.byte1switch a vector.
|
|
- Changed type CharClasses.CharClass to a vector. Arrays are now only
|
|
used for initializing the char classes; for lookup, they must be
|
|
finalized to a vector.
|
|
|
|
1999-08-03:
|
|
- Restructered the Dtd[Elements|Attributes|Notations|Entities] modules.
|
|
There are now two modules: DtdDeclare for operations concerning
|
|
declarations, and DtdAttributes for generating attribute values.
|
|
- Renamed AuxDtd to DtdManager.
|
|
- Renamed some functions from Entities to shorter names.
|
|
- Changed ParseDocument.parseDoc not to set O_VALIDATE to false if there
|
|
is no DTD. Instead those functions that would produce too many errors
|
|
without a DTD call hasDtd in order to find out whether there is one.
|
|
- Changed the error message for ERR_NO_DTD.
|
|
|
|
1999-07-29:
|
|
- Fixed a bug in the ParseContent.parseElementContent: character
|
|
references were passed to the application instead of reporting
|
|
an error.
|
|
- Removed ERR_DATA_IN_ELEM and ERR_CDATA_IN_ELEM; added ERR_ELEM_CONTENT
|
|
instead, which does the job for data, CDATA sections and charrefs.
|
|
- Added a boolean flag to HookData.DataInfo,indicating whether the
|
|
data is whitespace in element content. This information was available
|
|
only implicitly by the content spec of the parent element.
|
|
|
|
1999-07-26:
|
|
- Fixed a bug in the decoder and encoder, concerning surrogates: the
|
|
offset added/subtracted in combine/splitSurrogates was 0wx10000
|
|
instead of 0wx100000.
|
|
- DecodeUtil.isSurrogate ignored the high surrogates: fixed that.
|
|
|
|
1999-07-22:
|
|
- Renamed DecodeBasic to DecodeFile. Changes getByte such that it
|
|
closes the file (and removes it if temporary) before raising EndOfFile.
|
|
|
|
1999-07-20:
|
|
- Reimplemented the Uri structure to use strings for uris. (They may
|
|
only contain ASCII characters). Changed the result type of uriSuffix
|
|
to string.
|
|
- Moved the URI encoding functions to a new structure UriEncode.
|
|
A character "%" is only encoded if not followed by two hex digits.
|
|
Removed URI decoding, since that is superfluous.
|
|
- Added parser option O_WARN_NON_ASCII_URI. Changed
|
|
ParseLiterals.parseSystemLiteral to issue a warning if a non-ASCII
|
|
character occurs. Added a corresponding command line option
|
|
--warn-uri.
|
|
- Removed types CharInterval and CharRange from structure UniChar.
|
|
Added them to CharClasses, used only in Naming and NameClasses.
|
|
- Renamed type UniChar.CharVector to Vector for brevity.
|
|
- Renamed structures NameRanges and Naming to UniRanges and UniClasses.
|
|
|
|
1999-07-19:
|
|
- Renamed structure Chars to UniChar. Changed definitions such that
|
|
UniChar provides a structure Chars : WORD such that type Char =
|
|
Chars.word;
|
|
- Moved type Byte to DecodeBasic such that DecodeBasic provides a
|
|
structure Bytes : WORD such that type Byte = Chars.word;
|
|
- Changed other structures to use UniChar.Char and DecodeBasic.Bytes
|
|
instead of hardwired Word and Word8.
|
|
|
|
1999-07-14:
|
|
- Changed the DTD structure. The DTD is not a bunch of global variables
|
|
anymore; it is now a single data structure handed as argument to all
|
|
DTD functions. It must therefore be passed around through all DTD-
|
|
dependent parts of the parser and of all applications.
|
|
+ Removed O_INIT_DTD option. Instead, the parser expects an optional
|
|
DTD as argument. If that is NONE, a new DTD data structure is
|
|
initialized, otherwise tghe provided one is used.
|
|
+ Changed all applications to pass the DTD around.
|
|
- Changed functions ParseMisc.skipS and ParseRefs.skipPS. Instead of
|
|
raising NotFound on error, they call the hookError function themselves.
|
|
|
|
Changes from 1.1 to 1.2:
|
|
------------------------
|
|
1999-06-07:
|
|
- Replaced the --error-minimize option by --few-errors[=(yes|no)].
|
|
The old option was buggy and could only turn on an feature that
|
|
was on by default.
|
|
|
|
1999-06-04:
|
|
- Removed option --no-output/-n from fxesis and fxcopy.
|
|
- Modified the main functions of all applications: in case of
|
|
option errors, they raise now raise exception Exit instead
|
|
of calling OS.Process.exit.
|
|
- Added support for remote URIs.
|
|
+ In structure Config, value retrieveCommand defines a command
|
|
to be executed for URI retrieval.
|
|
+ Uri.retrieveUri calls this command for storing the entity
|
|
in a local file. It returns the name of the file and a flag
|
|
indicating whether a temporary file has actually been created
|
|
or the URI was local.
|
|
+ DecodeBasic.FILE has this boolean as additional parameter.
|
|
Function decClose removes the temp. file if the flag is true.
|
|
|
|
1999-05-10:
|
|
- Added new type AppFinal to HookData signature. hookFinish now
|
|
returns a value of type AppFinal. This is also the new type of
|
|
ParseDocument.parseDocument's result.
|
|
|
|
1999-05-03:
|
|
- Added support for XML syntax of XML Catalogs.
|
|
+ new function Uri.uriSuffix. Depending on the suffix of a URI,
|
|
catalogs are parsed in Socat syntax (.soc, .SOC) or XML syntax.
|
|
|
|
1999-04-23:
|
|
- Fixed bug: Dict.getByKey raised NoSuchEntry for unknown keys.
|
|
That made fxp fail with an uncaught exception if, e.g., an
|
|
unknown output encoding was given.
|
|
|
|
1999-04-15:
|
|
- Added functions Dict.clearDict and SymTable.clearSymTable.
|
|
- Removed references from the tables in Dtd. The Tables are now
|
|
initialized with clearDict/SymTable.
|
|
|
|
1999-04-14:
|
|
- Moved Hooks, HookData, Dtd, DtdOptions, Resolve and ParserOptions
|
|
to directory Params. Deleted directory Hooks.
|
|
- Added the start and end position to the arguments of most of the Hooks.
|
|
Made the appropriate changes in the parser modules and the apps.
|
|
- The parser is now reentrant, i.e., multiple instances are possible
|
|
at the same time.
|
|
- Made Dfa a functor, expecting the Dfa-relevant options in a
|
|
structure DfaOptions. Added a new functor for creating such a
|
|
structure.
|
|
- Made ParserOptions a functor in order to have multiple instances
|
|
of it. ParserOptions creates DfaOptions as a substructure.
|
|
|
|
1999-04-13:
|
|
- Made Dtd a functor, expecting a structure DtdOptions holding all options
|
|
concerning the DTD. Removed these options from ParseOptions.
|
|
- Removed O_SILENT, O_ERROR_DEVICE and O_ERROR_LINEWIDTH from ParseOptions.
|
|
These options now belong to the application.
|
|
- Fixed some bugs in the option parsers of applications.
|
|
- Fixed a bug in Dfa: exception DfaTooLarge was not visible through the
|
|
signature.
|
|
- Added an integer parameter to exceptions DfaToLarge and to
|
|
WARN_DFA_TOO_LARGE. It is the maximal allowed number of states.
|
|
- ErrorMessage no longer depends on ParseOptions.
|
|
|
|
Changes from 1.0 to 1.1:
|
|
------------------------
|
|
1999-03-29:
|
|
- Fixed ErrorMessage.errorMessage to complain about standalone 'yes' instead
|
|
of 'no'.
|
|
- Avoid multiple EndOfFile events for the same entity by adding a boolean
|
|
flag to DecodeError/Bytes exceptions.
|
|
|
|
1999-03-25:
|
|
- Improved error reporting; the position handed to hookError/Warning is now
|
|
- whenever possible - the first character of the concerned item.
|
|
Exceptions are checks done at the end of the DTD or of the document.
|
|
- Improved handling of wrong end-tags. The strategy is:
|
|
+ if the end-tag is for the current element, consume it and finish the
|
|
element;
|
|
+ otherwise, if it is for an open element, assume the end-tag for the
|
|
current element was forgotten, i.e., finish the current element but
|
|
retain the end-tag;
|
|
+ otherwise, if the current element requires further content in order
|
|
to satisfy its content model, ignore the end-tag;
|
|
+ otherwise consumne the end-tag and finish the current element.
|
|
In order to implement this, the following were necessary:
|
|
+ an extra argument openElems to ParseContent.parseElement. It is a list
|
|
of the indices of the types of the enclosing elements;
|
|
+ an extra component optEtag in the return vale of parseElement. It is an
|
|
option and holds information about an end-tag that was not consumed when
|
|
finishing the element;
|
|
+ appropriate changes to the code of parse[Mixed|Element]Content.
|
|
|
|
1999-03-24:
|
|
- fixed some bugs:
|
|
+ comparison of fixed attribute values is now correct.
|
|
+ Naming.isUnicode: 0x10000..0xFFFFF was not unicode.
|
|
+ ParseContent.parseMixedContent complained about character '>' even if
|
|
it was not part of the sequence ']]>'.
|
|
+ whitespace normalization in attribute values also affected characters
|
|
that were escaped by a char reference.
|
|
+ end-of-line normalization was done for the replacement text of internal
|
|
entities, but may only be done for the literal entitiy values.
|
|
+ default values in attlist declarations were checked not only for lexical
|
|
validity but also for declaredness of notation/entity names. This is now
|
|
done when the default value is used.
|
|
|
|
1999-03-22:
|
|
- Added support for the Socat syntax of XCatalog:
|
|
+ new subdir Catalog with a main functor Catalog
|
|
+ the parser functor now expects an additional structure argument Resolve
|
|
providing a function resolveExtId. That does not exist in BaseData any
|
|
more.
|
|
|
|
1999-03-16:
|
|
- Extracted Unicode-specific code from the Parser:
|
|
+ made a new directory Unicode.
|
|
+ moved Parser/Front/front.sml to Parser/entities.sml; renamed Front to
|
|
Entities.
|
|
+ moved Parser/Front to Unicode/Decode; renamed everything to Decode<...>,
|
|
frontEncoding to Encode.
|
|
+ moved Parser/Back to Unicode/Encode; renamed everything to Encode<...>,
|
|
backEncoding to Encode; moved back.sml to Apps/Copy/copyEncode.sml
|
|
+ moved Parser/Chars to Unicode/Chars.
|
|
- Changed the implementation of Decode and Encode:
|
|
+ UTF-7 is no longer supported.
|
|
+ new structure Encoding providing types and functions for handling
|
|
encoding names.
|
|
+ both Encode and Decode now raise exceptions instead of printing errors.
|
|
+ made the appropriate changes to Entities and CopyEncode.
|
|
|
|
1999-03-08:
|
|
- Moved fillArray for Front to FrontEncoding, renamed it to encGetArray.
|
|
- Hid implem. of type FrontEncoding.Encoding through the signature.
|
|
|
|
1999-03-05:
|
|
- Changed Front.fillArray to use a function parameter instead of a reference.
|
|
|
|
1999-03-02:
|
|
- Changed all parser functors:
|
|
+ expect only a structure Params containing former Hooks, Front, Dtd,
|
|
AuxParse and AuxRecover.
|
|
+ No other parser structures are arguments to functors.
|
|
- Removed the functions from DtdTables from the Dtd signature.
|
|
- Renamed Dtd to AuxDtd and DtdTables to Dtd.
|
|
|
|
1999-03-01:
|
|
- Added function hookWhite to signature Hooks.
|
|
- Added calls to hookWhite in ParseDtd.parseSubset and ParseDocument.parseDoc.
|
|
- Changed CopyHooks and CopyOutput to account for this:
|
|
+ removed third bool arg from CopyOutput.outComment/ProcInstr; they never
|
|
print a newline now;
|
|
+ removed printing of newlines from declaration hooks in CopyHooks;
|
|
+ removed function CopyHooks.inContent;
|
|
+ added hookWhite to CopyHooks;
|
|
- Added hookWhite to NullHooks and EsisHooks;
|
|
- Added LOC_SUBSET to datatype Location in ErrorData and ErrorString.
|
|
- Fixed ErrorMessage.errorMessage to print "Could not open file..." instead of
|
|
"Could open file..." for ERR_NO_SUCH_FILE.
|
|
|
