Current release


2015.2 (rev 9120) (Nov 2015)


The main focus of this release was C++ parser and Assist++ features. and Android applications builder in TheIDE (library does not yet support Android though).




Improved C++11 support.

Leap second of 2015 added to time routines.


GUI programming & graphics


Improved support of UHD displays.

New QTF command {{* is shortcut for {{~0/0 to simplify using invisible tables for organizing text.

PdfDraw now supports urls (e.g. when converting QTF/RichText to PDF).

RichText/QTF now support round borders for table cells.

ScatterCtrl: new features.




Assist++ and C++ parser now support C++11 and non-project headers, parsing ability is generally improved.

Android builder.

UTF16 support, UTF BOM autodetection.

Rename/Delete package functions.

Layout designer has new code generation features and can jump to C++ using the layout.

Editor now truncates files longer than 200MB / 1GB (32/64 bits ide) while loading, makes them read-only.

Editor now shows misplaced whitespaces in source files.

TheIDE now detects binary files and provides binary viewer.

Toolbar has new navigation icons and icons to switch editation mode (text/designer/binary).

Legacy GDB-backended debugger was refurbished and became 'Standard' debugger for GCC.

Icon designer now shows images as files icons when inserting image files.


Win32 releases


Win32 now does not come as .exe installer, but simple .7z archive, which acts as "portable" installation. Nothing is written to the registry, nothing needs to be installed, simply running "theide.exe" setups everything needed. (theide.exe is 64bit executable. For those unlucky to still run 32-bit os, there is theide32.exe).

There is once again 'mingw' variant which is coupled with TDM64 release of mingw-w64.



2015.1 (rev 8227) (Mar 2015)




U++ abandoned "default pick" semantics for containers. The transfer semantics now has to be specified explicitly, either as 'pick' or 'clone' (this is enforced in C++11 mode, in legacy mode old behaviour is maintained and pick/clone are optional).

New containers, based on fast-insertion arrays: InVector, InArray, SortedIndex, SortedVectorMap, SortedArrayMap. SortedIndex, SortedVectorMap and SortedArrayMap provide binary searches, while maintaining random access to the array, with performance comparable to binary tree based containers (e.g. std::map).

New Core/POP3 package - support for retrieving emails form POP3 servers.

Initial round of C++11 support (lambda callbacks, minor fixes)

A set of small utility functions findarg, decode, min/max now supporting more arguments. SplitTo and Merge for splitting/merging strings.

InFilterStream, OutFilterStream classes that can provide some sort of processing (e.g. compression) to regular streams.

New Date related functions EasterDay, GetMonths, GetWeek, GetWeekDate.

MIME / fileextension mapping functions FileExtToMIME and MIMEToFileExt.

Some ARMv7 related optimization (unaligned access, byte swaps).

SpinLock class.

Stream optimization methods GetPtr, PutPtr, GetSzPtr provide safe access to Stream internal buffer.

String/WString::Find(const String&) significantly speed optimized.

Value invalid casts now throwing exception ValueTypeError instead of panic.

WebSocket class.

[Stable]SortBy[Keys|Values] functions for sorting VectorMap, ArrayMap.

plugin/lz4 - adapted fast compression library

plugin/lzma - adapted high ratio compression library

plugin/glew - popular OpenGL utility library adapted as package


GUI programming & graphics


Gtk backend (U++ now using Gtk for host platform interface)

EditDateDlg, EditNumber simple function for entering single value (equivalent to EditText)

ArrayCtrl new methods to add/retrieve ValueMaps and ValueArrays, new CreateCtrl<T> method.

LineEdit heavily optimized to be able to work with huge files (>100MB).

X11 backend: Multimonitor support, removed flickering when opening window

Case insensitive replace now has "mimic case" option (mimics the case of first and next characters, so replacing "vector" -> "array", when match is "Vector", result is "Array").

Compilation errors now parsed and displayed nicely.

Assist++ context goto (Alt+J) now supports local variables (goes to declaration).

Layout/Icon designers now have find Search filter.

Ide now displays long numbers with thousands separators.

Syntax highlighting refactored, added highlighting of HTML, XML, .log files, .xsd files, .diff files, C++11 keywords highlighted, TODO and FIXME comments highlighted

Directory comparison tool.

Simple Json/XML viewers.

Comment/Uncomment block.

Selected identifier is now highlighted in all the text.
