Added a basic debugger:
- Debugging relies on a network socket for communication between the two processes. - You may need to accept a firewall warning to allow this communication. - The default listening port number is 4000. This can be changed with a startup option, for example: sbasic -p 4001

To debug a program:
- Turn on editing. Display the context menu (right mouse click), then click the “Editor” option. It should it show “Editor [ON]” when you next re-display the context menu. - Navigate to a .BAS file, then click the file name. This should display the program in the editor. - Press F5. A new window should appear. - Press F6 to step thru each program line, or press F7 to continue - Press ESC to end the debugging session. - To set a breakpoint, press Ctrl+T (C-t) on the desired program line. - The breakpoint doubles as a bookmark. Press (C-g) to goto the next bookmark/breakpoint line. - Now when you press F7 in a debug session, the program will pause at the breakpoint line.

Debugger limitations:
- The variables/stack data is currently unnamed. - The bytecode includes redundant line information for full comment lines

Improved INPUT widget including clipboard handling.
Update INKEY to return ALT, CTRL, ALT+CTRL key information
Added timer func support. When called as a function, the TIMER keyword accepts two arguments: a timeout value (in milliseconds) and the name of a call back FUNC. Note the timeout value only provides approximate millisecond precision.

Sub timer_func
    print "Timer called: ", Timer
End

Timer(5000, timer_func)
Print "Starting..."

While 1
  Pause 1
  Print "paused..."
Wend

Refactor FORM handling to use system object

REM create a form widget
input1.x = n
input1.y = n
input1.width = n
input1.height = n
input1.value
input1.label
input1.type  - [label|link|listbox|choice|text|button|image
input1.name - file name for image button type
input1.backgroundColor
input1.color
input1.visible
input1.selectedIndex
input1.length
input1.noFocus
input1.onclick = func

REM creates a form object
f.input << input1
var f = form(f)

REM
f.value = "text"
f.focusColor = "green"

REM push messages through the system event queue
f.doEvents()

REM close the form
f.close()

Please refer to examples: memoryTest.bas, calc.bas, sokoban.bas

Update IMAGE handling.

There are two supported image formats PNG and XPM. PNG images can to be loaded using the OPEN command, or by passing the filename string as an argument to the Image creator function. XPM images can also optionally be passed as a string argument to the Image creator function.

REM Use the OPEN statement to open the image file
Open "1234.png" as #1

REM create an IMAGE object
i = Image(#1)

REM Display the image - passing optional x, y, zindex, opacity attributes
i.Show([x, y [, zindex [, opacity]]])

REM change the image attributes
i.x = 100
i.y = 10
i.offsetTop = 1
i.offsetLeft = 1
i.width = 100
i.height = 100
i.zindex = 0
i.opacity = 0

REM display the image with current attributes
i.Show()

REM hide the image
i.Hide()

... print the image details
PRINT i

REM create an XPM image
ar << "30 30 770 2"
ar << "     c None"
ar << ".    c #5B3015"
...
ar << ". + @ # $ @ % & * = - ; > , ' ) ! ~ { ] ^ / ( _ : < [ } | 1 "
...
i2 = image(ar)
i2.x=15
i2.y=15
i2.zindex=1
i2.show()

Added WINDOW system object to control the ansiwidget

REM create a window object
w = Window()

REM Create a status message
w.status("Hello")

REM draw into an inset screen
w = window()
w.insetTextScreen(5,10,90,90)
for i = 0 to 200
  ? "This is in the text screen"
next i

REM display in the text based screen
w.textScreen()
print "This is the text mode screen"

REM switch between graphics screens
w = window()
print "on screen1... pausing"
pause
w.graphicsScreen2()
print "on screen 2.... pausing..."
pause
w.graphicsScreen1()
print "back to 1"

REM  display an alert
local wnd = window()
local msg = "You must restart SmallBASIC for this change to take effect"
wnd.alert(msg, "Restart required")

REM Display a menu
local w = window()
w.menu("one", "two", "three")

REM Display the keypad
local w = window()
w.showKeypad()

0.11.16

This release includes language and performance improvements.

Variables:

The MAP variable type combines the features of previously separate “User Defined Structures” and “Associated Array” variables. The MAP provides value-key pair access along with array or dotted notation. The MAP can be initialized from a String variable using the ARRAY command. The ARRAY command supports JSON (Javascript object notation) syntax.

The MAP can be converted back into a JSON string using the STR command. You can test whether a variable is a MAP using the ISMAP command.

The ARRAY command can be used to process web services results. For example: https://raw.githubusercontent.com/smallbasic/SmallBASIC/master/samples/distro-examples/devio/google.bas

The REF variable type is a “reference” to another variable (like a pointer in c). You create a reference by assigning a variable with the BYREF keyword (or @ symbol). For example LET c = @ b. You can test whether a variable is a reference using the ISREF command.

Commands:

The IMGW and IMGH commands have been replaced with the single IMAGE command. IMAGE takes a file pointer and returns a system object allowing full control of the image placement. Note: In this release only the language aspect has been implemented. This feature will be completed in the next build.

Added the SHOWPAGE command. This command is used to display pending graphics operations allowing for smooth animations.

Added TRY/CATCH support - see http://smallbasic.sourceforge.net/?q=node/1229

Compiler:

It is now possible to use unary-operators on array elements, for example a(0)++.
Handling of round brackets with FUNC calls has been fixed.
Renamed command “#UNIT-PATH:” to “UNITPATH”
Renamed command “#INC:” to “INCLUDE”
Fixed/implemented INCLUDE command.

  Then in the foo.bas file:

  Unit other.something.Foo
  export my_var

  The unit file should be saved in $UNITPATH/other/something.
  If not defined, $UNITPATH is inferred as the host program
  file directory.

2007-10-10 * A runtime error is now created in lieu of crashing when you pass a value less than 0 to the LEFT and RIGHT string commands. * The runtime error for LEFT,RIGHT,REPLACE,MID,INSTR,RINSTR now includes the invalid index in the message

2007-08-31 * Fixed a problem referring to UDS fields from an array eg x = foo(0).x

2007-08-18 * Fixed a problem with the short-circuit eval code causing incorrect true/false return IP’s being calculated

2007-08-02 * The IN operator when applied to arrays now returns the 1 based index position, eg: a << “cat” a << “dog” ? “dog” in a ’prints 2

2007-07-21 * Implemented experimental logical expression short-circuit evaluation

2007-07-12 * (re) Implemented user defined structures * AnsiWidget added to FLTK core package

2006-08-16 * Fixed error message with unterminated strings in a sub or func. complained about missing END instead of the missing ” char * Quoted strings no longer required the end quote char. A new line is taken as the end of string.

2006-08-12 * added support for func/sub pointer variables used with the call statement:

      func foo(s)
       foo="foo!"+s
      end
      sub bar
        ? "in bar"
      end
      p = @foo
      ? call(@foo, "#")
      ? call(p, "%")
      pb = @bar
      call pb
      call @bar

* USRCALL has been removed since it never worked and the above
      is a better replacement (IMHO)

2006-07-28 * updated chain command to take string or array of string arguments in lieu of a file name. After calling this command, the calling program now successfully resumes. * added HAVE_C_MALLOC to replace complicated memory routines with simple malloc/free calls * added GRID+TAB button support to GTK build

2006-05-27 * added form support to GTK build

    Human language depented files for messages and keywords.
    The messages and the keywords can be easily translated to another language.
    This is not suggested because that means incompatible source-code but it is very usefull for education purposes;
    I believe that, the kids will work better if they are using their natural language
    (and we are very sensitive on that matter).
    I suggest to the "translators" to be very carefull, there is no mean on a word-to-word translation.

    several internal changes for easy development.
    --- cxx_sb.hpp provides a new iterface to whole SB.
    --- SB can compiled as a C or C++ library. That would
    --- help a lot the IDEs developers. Main Makefile
    --- splitted, it is working like main-menu now.
    FLTK IDE added but not finished yet.
    --- Actually that shows the power of the libsbasic.
    --- It is very easy now to build IDE. Unfortunately
    --- I am no friend of GUI, I've never tried Qt or GTK.

    new code: lopen_bridge.h
    --- I rewrote the VMTs. The code was a mess. Several parts of SB
    --- uses #def blocks just to do simple tasks with open/close command-set
    --- So, I wrote a "driver" which cleans a lot of those parts by using
    --- real std-c emu of functions open/close for PalmOS and VTOS.
    update: new VMT
    --- VMTs are now basic part of the system. Because of lopen_bridge.h is
    --- easy portable too. In VMTs is stored a fake environment-variable table,
    --- VMTs are used for memory swaping, and will be used as basic-level database.
    update: PalmOS, On PalmOS 3.5+ the opt_safedraw (SDK3.5 draw functions) is
    --- used by default on 3.5+.

    Trying to support nested arrays.
    --There are some problems with nested arrays.
    --Nested arrays are not visible to SB compiler so
    --SB does not stores optimized info for them.
