AL-IV:    Versions history

 

May, 7, 2018 - new version: 0.90.3

  • Changes:
    • Great progress in compiling to the Python: simplest GUI applications are compiling and working;
    • Python: {Clipboard} works now via tkinter (GUI library for the Python), so it is not necessary to install additionally (pyperclip);
    • {Paint_turtle}: sinse in Windows 8 incorrect colors can be returned by system functions, the 'BUTTON_TEXT' color is now used as a default normal color, and the method Set_normal_color added to set a desired normal color;
    • All visual tests are moved from AL4\Library\Visual to AL4\Test_visual_projects; OTLv4.h now is searching in %OTL% directory (%OTL% environment variable is required);
  • Fixes:
    • {Stream}.Get_line ==> can now load lines from unix text files (#LF - ended);
    • C#: {Button} autosized height was too low in systems with large font set, now recalculated on base of default font;
    • C++: {Random}.Probable ==> returned 0.0 always;
    • C++: analyzing errors was too suspicious: for case of any word "error" in an output it decided that it is not necessary to run compiled tests/application.

 

 

 

April, 12, 2018 - version: 0.90.2

  • Changes:
    • It is disabled to use ++/-- operations in expressions containing also && / || operations;
    • Good progress in compiling to the Python: console applications are compiling and working (under Windows and Linux);
  • Fixes:
    • Operations IN/!IN are disabled for case of checking a real number value inclusion into an array of real numbers.

 

 

 

April, 12, 2018 - version: 0.90.1

  • Changes:
    • {Stream}: faster loading strings in ANSI encoding;
    • C++: compiler option $SSTRINGS abandoned;
  • Fixes:
    • Delphi/KOL: Write_file_stream did not write any;
    • C#: loading text in an ANSI encoding;
    • Delphi/VCL: it was running 100% one processor core always;
    • Optimization with "inlining" a function body is not accepted if an "inlined" function itself calls functions from the classe which is not importing in the target function (otherwise there are problems in a target compiler).
  • IDE AL4:
    • fixes and improvements (see in Ide_al4.al4 at the end of source file).
    • Pascal (partial) syntax highlighting added;
    • Painting speed increased.

 

 

 

April, 8, 2018 - version: 0.90.0

  • Added:
    • Compiling the AL-IV project to a Python program. For now, for console applications only. (The test project Hello_world is compiling and working).
  • Changes:
    • Unbalanced quotations errors is replaced by a warning after the END.
  • Fixes:
    • Using '" ... "' not in the first line of a multi-line string;
    • Delphi/KOL: Running compiled application in earlier OS (Windows NT4);
  • IDE AL4:
    • fixes and improvements (see in Ide_al4.al4 at the end of source file).
    • syntax highlighting added for other programming languages (now, implemented for Python and FoxPro).

 

 

March, 21, 2018 - version: 0.89.3

  • Changes:
    • A semantics of the modifier TESTED was changed: a construction TESTED(nn) now means that class is tested at least on nn%. The TESTED modifier without parameters as well as for case when UNTESTED is not specified means that the class is proclaimed to be tested on 100%. Too strong proclaiming (with a gap more then 5%) is accounting as an error;
    • The language syntax: A special string literal format is added:
      '"..."' - such string constants can be placed only in separate lines of code, restricting it using mainly with long (multi-line) string constants; such strings allows to write any quotations to be written in a string except the ("') pare of quotations used only at the end of such triple-quoted string; therefore the way to check balancing quotes is still working for all other lines of code;
    • The language syntax:: Multi-line comments format is changed. Comments should start with the symbol */ and ended with /*. AL-IV code always should be located between symbols /* and */ as it would be comments for another language even if only AL-IV code is found in a file;
    • The DEBUG statement now can be written only in uppercase, the debug variant is no more supporting.
  • IDE AL4:
    • fixes and improvements (see in Ide_al4.al4 at the end of source file).

 

March, 16, 2018 - new version: 0.89.2

  • Changes:
    • Compiling of the compiler with C++ (code of AL4.h, AL4.cpp was moved to separate files from the compiler code, so its final adoption to a final project string options became possible);
    • C++ applications for Linux can now be built in Linux with the AL-IV-to-C++ compiler prepared to work in Linux;
  • Fixes:
    • C++: array[].Insert(At, Value);
    • C++: {System_functions}.Parameter(i) ;
    • C++, Delphi, Java: {System_functions}.MIN_INT (typo FFFF_FFFF instead of 8FFF_FFFF);

 

March, 11, 2018 - version: 0.89.1a

  • Fixes:

March, 10, 2018 - version: 0.89.1

  • Changes:
    • A capability added to compile C++ visual projects with GCC (for Linux);
    • {Bitmap} is drawn without any transformations set to the destination {Canvas} by Draw and Stretch_draw methods: destination point specified is always assumed relative to the top-left corner of the canvas - the reason is that not all platform support such bitmap draw operation natively and sufficiently fast, at least in Linux X this can be a problem;
  • Fixes:
    • Compiling C++ visual projects;
    • Building C++ projects via MSBuild;
    • C++: {Canvas}.Offset (ambiguous conversion to pixels before the translation);
    • C#: {Canvas}.Arc(...., FALSE);

 

March, 5, 2018 - version: 0.89.0

  • Changes:
    • A capability added to compile C++ console projects with GCC (for Linux); For now, compiling of the test code and running it are processing in the Windows. Then, final c++ project is created together with a command file _call_gcc.cmd to run in Linux. After compiling/building in the Linux, the executable is created and can be launched there.
  • Fixes:
    • Creating a console with keyboard input capability in a windowed project for C++ (MS Windows);

 

February, 26, 2018 - version: 0.88.0

    • all the warnings/errors now are written to the Compiler_messages.html (some messages were not stored there);
    • compiling a function call from a TEST function could lead to creating an incorrect (non-compilable) code;
    • compiling the ending TEST block could be interrupted earlier because of too optimistic prediction of iterations amount;
    • {Form}.Set_left (C++, Java);
    • C++: tests for GUI-applicationa are compiled for and executed in a GUI mode (rather then in console mode) - otherwise it is not possible to test GUI applications;

November, 22, 2017 - version: 0.85.4

  • Changes:
    • A requirement added on code structure: block statements (CASE, FOR, FOREVER, PUSH, DEBUG, debug) must always start from a new line (i.e. it is not allowed to write those in the same line following ELSE or in CASE branches follwing ':' or '?').

    • direction in vertical_wheel (Java, Delphi/KOL);
    • Setting {Paintbox}.Set_content_size less then current Visible_area_size (by width, height - Delphi/VCL);
    • Setting modifiers Ctrl, Alt, Shift in the field {Form}.Key for all the mouse and keyboard events (Java);
    • {Paint_lines} always stores values set by the method Move_top_left_to (for both vertical and horizontal directions) and returns it in case when a difference between that value and a correspondent scrollbar position is less then 1 in absolute value (this fixes rounding problem which occur in result of rounding to nearest integer of a value assigned to a scrollbar current position property);
    • C# compiler errors analyzing: not only word "error" is checking but its neighboring characters to ensure that error is not a part of longer word (i.e. a class name);
    •  code generation for STORED parameters (C++);
    • generating [].Delete(index++) (in case when index is auto-decremented or auto-incremented).
  • A small present to myself for anniversary a year from the first publication: an own code editor for AL-IV started (and sufficiently progressed). It is planned to finish its developing up to the end of the year.

 

November, 15, 2017 - version: 0.85.3

  • Added:
    • {Control}.Location ==> {rect} - control coordinates in a parent form rather then (Left, Top returning coordinates relatively to a parent column).
  • Fixed::
    • Generating code for NATIVE directives not starting from "using" (C#): moved into a resulting class;
    • Optimization in case of inlining of a function containing in an expression a type cast of class: RESULT = x.y.z.{Some_class};
    • {Control}.Top (Delphi/KOL);

 

November, 12, 2017 - version: 0.85.2

  • Changes:
    • on C++ code generation, in function Main following code is added: _CrtSetDbgFlag(0); (to prevent very long delay while reporting about memory leaks, on the application end - though these are not memory leaks actually but results of STL working).
  • Added:
    • A enumeration {Paintbox}.{cursor}, a field Cursor|_shape, a method Set_cursor(New_c|ursor_shape)
      -- it seems does not work for Delphi VCL (VCL bug?);
  • Fixed:
    • Generating code for NATIVE directives not starting from "using" (C#): moved into a resulting class;
    • {Canvas}.Measure (C# incorrectly calculates size for a string having trailing spaces);
    • special key codes handling (C++/wx);
    • code generation  for PUSH statements in CASE branches (C++ compiler can not initialize local variables);
    • For the {Paintbox} (and its descendant {Paint_lines}) when the option "F" is set (focusable), then all the navigation keys are handled in the control itself (all the languages/frameworks);
    • {Localize_str} for Java - in case when Set_directory_lang was not called;
    • {Paint_lines}.provide_caret (Java) - removing old caret before setting new one.

 

November, 9, 2017 - version: 0.85.1

  • A capability provided to use variables of class {Object} (and assigning NONE to them).
  • Added:
    • {Canvas}.System_color({system_color}, enumeration {system_color};

    • A visual component {Paint_tabs}:
  • Fixed:
    • {Canvas}.Offset , Measure - pixels were used, now current units of the canvas are used (default are points);
    • mouse coordinates {point} mouse for all the mouse events (in Java & C++);
    • pop-up menu coordinates for {Tray_icon} (C++);

 

November, 5, 2017 - version: 0.85.0

  • A capability added to specify parameters restrictions in form of comparison relations, e.g.:
    , IF P1 IS CONST, THEN P1 >= 0 ...
  • Fixed:
    • {Canvas}.Offset, Rotate - made the same for all the frameworks.
    • calling {Form}.resize event provided on form maximize / restore (Java).
  • A control {Paintbox} with content scroll is finished.
  • A visual control {Paint_lines} (based on {Painbox}) added with support of blinking caret and specific methods to handle lines.
