In Excel-generated + documents, styles only reference named styles as their parents. But in + 3rd-party generated documents, styles referencing unnamed styles as their + parents can occur. + +* gnumeric + + * fixed a crash when the document model returned a null pointer when a + reference resolver interface was requested. + +orcus 0.19.1 + +* general + + * implemented orcus::create_filter() which instantiates a filter object of + specified type. The returned object is of type + orcus::iface::import_filter. + + * moved test cases for format detection to the respective filter test files. + +* gnumeric + + * fixed a bug where the import filter did not set the formula grammer prior + to importing. + +orcus 0.19.0 + +* general + + * added support for allowing use of std::filesystem, + std::experimental::filesystem or boost::filesystem per build + configuration. + +* xlsx + + * refactored styles import to use style indices returned by the document + model implementer rather than using the indices stored in the file. This + allows the implementer to aggregate some style records and re-use the same + index for records that are stored as different records in the original + file. + +* xls-xml + + * fixed a bug where column styles were not applied to the correct columns + when the starting column index was not 0. + +* gnumeric + + * overhauled the Gnumeric import filter to fix many bugs and support many + missing features relative to the other filters included in orcus. Most + notable mentions are: + + * cell styles + + * rich-text strings + + * named ranges + + * row heights and column widths + + * merged cells + +* parquet + + * added partial support for Apache Parquet import filter. This is still + heavily experimental. + +orcus 0.18.1 + +* sax parser + + * added support for optionally skipping multiple BOM's in the beginning of + XML stream. This affects all XML-based file format filters such as + xls-xml (aka Excel 2003 XML). + +* xml-map + + * fixed a bug where XML documents consisting of simple single-column records + were not properly converted to sheet data. + +* xls-xml + + * fixed a bug where the filter would always pass border color even when it + was not set. + +* buildsystem + + * added new configure switches --without-benchmark and --without-doc-example + to optinally skip building of these two directories. + +orcus 0.18.0 + +* general + + * fixed the flat output mode to properly calculate the lengths of UTF-8 + encoded strings. + + * replaced all uses of std::strtol() to parse_integer() to properly parse + strings that are not necessarily null-terminated. + + * added a new output format type 'debug-state' which dumps the internal + state of the populated document model in detail. This can be useful + during debugging. + + * separated the import_shared_string interface implementation from the + backend shared strings store per separation of responsibility. + + * merged the foo_t and foo_active_t struct pair, such as font_t and + font_active_t, in the styles store into a single type using std::optional. + + * revised the documentation and public API and cleaned things up where + necessary. + +* ods + + * reimplemented the number format styles import to correctly keep track of + element stacks and correctly perform structure checks to detect malformed + documents. + + * added new interface to import named styles applied to columns. + + * added new interface to import attributes for asian and complex scripts for + the folloiwng font attributes: + + * font name + + * font size + + * font style + + * font weight + + * re-designed the styles import interface to make it multi-level. + + * re-worked the import of the style:text-underline-width attribute to make + its handling more in line with the specifications. + +* xls-xml + + * added support for importing wrap-text and shrink-to-fit cell format + attributes. + + * added support for importing cell-hidden and locked attributes. + + * added support for importing direct and named cell formats applied to + columns and rows. + +* xlsx + + * added support for importing wrap-text and shrink-to-fit cell format + attributes. + + * added support for importing direct and named cell formats applied to + columns and rows. + +* xml-map + + * added a new interface to pass the encoding information to the document + model so that it can correctly decode non-UTF-8-encoded string values. + +orcus 0.17.2 + +* ods + + * fixed a bug where the state of style:cell-protect="none" was not + explicitly pushed, thereby having had the same effect as not having this + attribute. After the fix, style:cell-protect="none" will explicitly push + the hidden state to false, locked state to false, and the formula-hidden + state to false. + +orcus 0.17.1 + +* general + + * addressed a number of coverity issues. + + * removed a variety of compiler warnings. + +* ods + + * re-generated sax parser tokens from ODF v1.3. + + * revised the style import code to only push style attributes that are + actually specified in the XML. + +* xls-xml + + * revised the XML structure validation strategy to ignore any mis-placed + elements and their sub structures rather than aborting the import. + +orcus 0.17.0 + +* general + + * set the baseline C++ version to 17. + + * cleaned up the public API to replace pstring with std::string_view, union + with std::variant, and boost::optional with std::optional. With this + change, the public API no longer has dependency on boost. + +* spreadsheet document + + * switched to using ixion::model_iterator for horizontal iteration of cells + instead of using mdds::mtv::collection. + + * fixed a bug where exporting a spreadsheet document containing adjacent + merged cells regions to html incorrectly exported the merged cell areas. + +* xlsx + + * cached cell values are now correctly loaded from the file. + +* sax parser + + * utf-8 names are now allowed as element and attribute names. + +* css parser + + * unquoted utf-8 property values are now allowed. + +* orcus-json + + * fixed segmentation fault when using --mode structure with the Windows + build. + + * added yaml output option. + +* xml-map + + * fixed a bug where mapping of an XML document with namespace aliases + sometimes corrupts the alias values. + +* python + + * added orcus.FormulaTokenOp enum type which describes type formula token + operator types in a more finer grained manner. + +* documentation + + * added notes to how to use orcus-xml and orcus-json to map XML and JSON + documents to spreadsheet documents. + +orcus 0.16.1 + +* fixed a build issue on 32-bit linux platforms, which was indirectly caused + by ixion. + +* fixed json parsing bug caused by an uninitialized variable, which manifested + itself on debian 32-bit platform. + +* removed compiler warnings on unused variables from the base parser handlers. + +orcus 0.16.0 + +* general + + * full formula recalculations are now optional when loading documents. It + makes more effective use of cached formula results. + + * added the option of failing on the first faulty cell, or skipping them. + + * fixed a bug that caused the threaded_sax_token_parser to deadlock. + + * added base parser handler classes in the public headers so that they can + be sub-classed to overwrite necessary handler methods. + +* json-parser + + * parsing of numeric values are now more strict for better conformance to + the specs. + +* ods + + * added support for loading named expressions from ods documents. + + * fixed an infinite loop when loading one of the attached ods documents from + https://bugs.documentfoundation.org/show_bug.cgi?id=82414 + +* xlsx + + * fixed a segfault when loading the xlsx document from + https://bugs.documentfoundation.org/show_bug.cgi?id=83711. + +* xls-xml + + * fixed a bug that prevented formulas from referencing cells located in + later sheets. + +* xml-map + + * adjusted the xml path expressions to be more like XPath. Previously, an + attribute was expressed as '@' in the old expression, but XPath uses '/@'. + The new expression uses '/@' for an attribute. + + * added the ability to identify and import ranges from XML documents without + map file. + + * added the ability to generate map file from XML documents for user + customization. + + * added support to specify default namespace in the map file. + +* python + + * added orcus.Cell class to represent individual cell values and attributes. + + * fixed several memory leaks in the python binding layer. + + * modified orcus.csv.read() function to take string input, instead of bytes. + + * added __version__ attribute to the orcus module. + + * cleaned up orcus.detect_format function to only take the stream parameter. + + * added named_expressions properties to Document and Sheet class objects. + + * added Python API to bulk-process a number of spreadsheet documents + (orcus.tools.file_processor). + + * added Python API to download attachments from bugzilla services via REST + API (orcus.tools.bugzilla). + +orcus 0.15.4 + +* fixed a build error with gcc 10 with LTO. For more details, visit + (https://bugs.gentoo.org/715154). + +* removed potentially non-free specification and schema files from the + package. + +orcus 0.15.3 + +* xml-map + + * fixed another bug related to filling of cells down the column in a linked + range with nested repeat elements. The bug would occur when the field in + a linked range is more than one level deeper than the nearest row group + element. + +* xls-xml + + * fixed a bug where TopCell and LeftCell attributes of the Table element + were not properly honored. + +orcus 0.15.2 + +* xml-map + + * fixed a bug that prevented filling of cells down the column in a linked + range with nested repeat elements. The bug would occur when the field in + a linked range is associated with an element content rather than an + attribute. + +* xls-xml + + * added code to properly pick up and pass the number format codes, including + named number format values such as 'General Date', 'Long Time, 'Currency' + etc. + +* fixed a build issue on older macOS environment, related to passing an rvalue + to a tuple expecting a const reference. The root cause was a bug in libc++ + of LLVM < 7. + +* fixed a build issue with gcc5. + +orcus 0.15.1 + +* switched xml_map_tree to using boost::object_pool to manage the life + cycles of the objects within xml_map_tree, to avoid memory + fragmentation. + +* fixed incorrect handling of newly created elements in xml_map_tree. + +* fixed segfault caused by double deletion of allocated memory for + xml_map_tree::element, which seemed to happen only on 32-bit gcc builds. + +* fixed weird test failures related to equality check of two double-precision + values, caused probably by aggressive compiler optimization which only seems + to get triggered in 32-bit gcc builds. + +orcus 0.15.0 + +* spreadsheet interface + + * import_sheet::fill_down_cells() has been added as a required method, to + allow the import filter code to duplicate cell value downward in one step. + +* json parser + + * added test cases from JSONTestSuite. + + * fixed a bug on parsing an empty array containing one or more blank + characters between the brackets. + +* sax parser + + * fixed a bug on parsing an attribute value with encoded character + immediately followed by a ';', such as '&;'. + + * fixed a bug on parsing an assignment character '=' that either preceded or + followed by whitespaces in attribute definition. + + * optionally use SSE4.2 intrinsics to speed up element name parsing. + +* orcus-xml + + * revised its cli interface to make use of boost's program_options. + + * orcus-xml-dump's functionality has been combined into orcus-xml. + + * map mode now supports nested repeat elements to be mapped as range fields. + +* orcus-json + + * map mode has been added to allow mapping of JSON documents to spreadsheet + document model. This mode either takes explicit mapping rule via map + file, or performs automatic mapping by auto-identifying mappable ranges by + analyzing the structure of the JSON document. + + * structure mode has been added to display the logical structures of JSON + documents. + + * significantly improved performance of json document tree by utilizing + object pool to manage the life cycles of json value instances. + +* xls-xml + + * added support for importing named color values in the ss:Color attributes. + + * added support for handling UTF-16 streams that contains byte order marks. + +* spreadsheet document + + * significantly improved performance of flat format output generation. + +* internal + + * string_pool now uses boost's object_pool to manage the instances of stored + strings. + + * file_content class has been added to memory-map file contents instead of + loading them in-memory. + + * memory_content class has been added to map in-memory buffer with the + optional ability to perform unicode conversion. + + * dom_tree has been renamed to dom::document_tree, and its interface has + been cleaned up to hide its implementation details. + +orcus 0.14.1 + +* addressed a number of coverity issues. + +* improved precision of points-to-twips measurement conversions by + reducing the number of numeric operations to be performed. This + especially helps on i386 platforms. + +orcus 0.14.0 + +* spreadsheet interface + + * import_data_table::set_range() now receives a parameter of type + range_t. + + * import_sheet::set_array_formula() interface methods have been + removed and replaced with import_sheet::get_array_formula() that + returns an interface of type import_array_formula. + + * import_formula interface class has been added to replace the + formula related methods of import_sheet. As a result, + set_formula(), set_shared_formula(), and set_formula_result() + methods have been removed from the import_sheet interface class. + + * import_auto_filter::set_range() now receives a parameter of type + range_t, rather than a string value representing a range. + + * import_sheet::set_fill_pattern_type() interface method now takes + an enum value of type fill_pattern_t, rather than a string value. + +* xls-xml + + * pick up the character set from the XML declaration, and pass it + to the client app via import_global_settings interface. + + * support importing of array formulas. + +* xlsx + + * support importing of array formulas. + + * fixed a bug where sheet indices being passed to the append_sheet() + interface method were incorrect. + +* shared formula handling code has been re-worked. + +* spreadsheet::sheet class has been de-coupled from the import and + export interfaces. + +* previously known as import_styles class is now split into styles + class and import_styles factory wrapper class. + +* sax_parser now gracefully ignores leading whitespace(s) if any, + rather than aborting the parsing for it's not a valid XML stream + to have leading whitespace(s). In the future we should make this + behavior configurable. + +* python + + * add orcus.xlsx.read() function that takes a file object to load + an xlsx file as a replacement for orcus.xlsx.read_file(). + + * add orcus.ods.read(), orcus.xls_xml.read(), orcus.csv.read(), + and orcus.gnumeric.read() functions. + + * add orcus.Sheet.write() method which exports sheet content to + specified format. For now only the csv format type is + supported. + +* xml_map_tree no longer requires the source stream persisted in + memory between the read and write. + +* the sax parser now stores the offset positions of each element + rather than their memory positions, in order to make the position + values usable between duplicated stream instances. + +* xml_structure_tree to support selection of an element by element + path. + +* document + + * correctly set the argument separator depending on the formula + grammar type. This change fixes loading of ods documents with + formula cells. + +* fixed a build issue with boost 1.67. + +orcus 0.13.4 + +* xls-xml + + * fix incorrect handling of formula cells without result caches. + +* fix incorrect parsing of invalid XML documents with multiple + self-closing root elements. + +orcus 0.13.3 + +* fix the handling of alpha values passed to set_fill_fg_color() and + set_fill_bg_color(). A value of 255 means fully opaque whereas a + value of 0 means fully transparent. + +* fix the solid fill color import, to use the foreground color + instead of the background color. + +* xlsx + + * import colors to disgonal borders. + + * remove carriage returns from multi-line cell strings. + +* xls-xml + + * import border colors. + + * import hidden row and column flags. + +orcus 0.13.2 + +* xls-xml + + * import column width and row height properties. + + * import solid fill colors in cells. + + * import text alignment properties. + + * import cell borders. + +* xlsx + + * import justified and distributed text alignment properties. + + * fix exception being thrown when the diagonal element is + encountered. + + * import diagonal cell borders. + +orcus 0.13.1 + +* use a more efficient way to set format ranges in spreadsheet + model. + +* support single quoted strings in the css parser. + +orcus 0.13.0 + +* fix incorrect parsing of XML 1.0 documents that don't include + header declarations. + +* fix incorrect parsing of XML elements and attributes whose names + start with an underscore. + +* orcus-csv: add an option to split content into multiple sheets in + case it doesn't fit in one sheet. + +* add csv dump mode for all spreadsheet document based filter + commands. + +* orcus-ods: suppress debug outputs unless the debug flag is set. + +* orcus-xlsx: correctly import boolean cell values. + +* add experimental cmake-based build support, primarily for Windows. + +* add initial support for importing select sheet view settings in + xlsx and xls-xml. + +* add API for directly constructing json document trees. + +* support import of cell formats for xls-xml. + +* support single-quoted attribute values in the sax xml parser. + +* orcus-xml: fix incorrect mapping of XML range data to sheet range + when the first column contains one or more empty elements. + +* support import of named expressions for xlsx and xls-xml. + +* support import of formula cells for xls-xml. + +* implement pivot cache import for xlsx. + +* fix a number of crashes in the csv parser. + +* fix a number of crashes in the json parser. + +* fix a number of crashes in the yaml parser. + +* integrate orcus into gitlab's continuous integration. + +orcus 0.12.1 + +* fix build when --disable-spreadsheet-model is specified and the + ixion headers are not present. + +* fix loading of file streams on Windows. + +* get the debug flag to work again. + +orcus 0.12.0 + +* handle escaped unicode in the xml parser + +* improve odf styles import + +* implement threaded xml parser + +* implement threaded json parser + +orcus 0.11.2 + +* make it buildable with mdds-1.2. + +orcus 0.11.1 + +* fixed various build issues with MSVC and clang on OSX. + +orcus 0.11.0 + +* remove boost dependency from the public headers. + +* implement JSON parser and document storage model. + +* implement YAML parser and document storage model. + +* add orcus-json. + +* add orcus-yaml. + +* improve parse error output from the XML parser. + +* use enum class in import_style::set_border_style(). + +* support non-local file import. + +orcus 0.1.0 + +* initial release. |
