SpecBAS 0.900 Released
« on: 20. April 2017, 12:16:09 »
Against my better judgement, here's 0.900. It's got lots and lots new, but mostly the new shiny is the editor.

You can indent your code, you can edit it inside the listing window. You can use the Direct Command window just the same as you used to - but do read the supplied Readme file first for important control key changes! Oh, you can also cut, copy and paste code to and from the listing window.

It's not been extensively tested, so please, PLEASE report bugs if you find them!

Get it here.

Here's the What's new:

Quote
v0.0.0.900
==========

NOW IN 64BIT! SpecBAS32.exe and SpecBAS64.exe are newly available. The 64bit version is experimental, so feedback will be nice :)
NOW IN OPENGL! Using OpenGL in selected binaries (marked -gl) to display the screen, reducing the workload on the CPU.


Added:

  Added word (or rather, "line") wrapping. The direct command window can be used as it used to now, and lines will be forced to fit. Change the EDITORWRAP sysvar to enable/disable it.
  DeleteAll banks no longer removes system banks unless SpecBAS quits - preserves keyclicks.
  Added colour capability to POLYLINE/POLYGON with an array as a parameter
  Added particle engine - PARTICLE array() FRICTION n GRAVITY m,o
  Added radius to PLOT Array() handler in Array(n,4)
  Added INVERSE, ITALIC, BOLD and TRANSPARENT 8 - leave them as they are, same as Sinclair BASIC
  Changed Ctrl+Up/Down to jump to line starts prev/next
  Added Ctrl+Backspace/Delete for deletion of words
  Added F9 (run) and F10 (goto) hotkeys
  Added ITALIC and BOLD commands. PRINT embeddable, but BOLD is only for mono fonts.
  Added RENUMBER and DELETE handlers to the new editor.
  Added Listing reordering on CTRL-R.
  Added new editor, supports indentation and split lines.
  Further CPU reductions.
  Reduced idle CPU usage due to mouse moves triggering screen updates.
  Optimisation to IF/ELSE addressing string characters
  Reduced CPU usage when idle and during the editor quite significantly
  Fixed problems with using compound assigns in numeric arrays
  OVER 11 - Recolour mode. Any pixel that has a value of 0 gets the current PAPER colour, otherwise INK
  WINDOW FLIP id and WINDOW MIRROR id added - They do exactly what they say they do
  GRAPHIC FLIP and GRAPHIC MIRROR now also take a stringvar which, when containing a valid graphic, will flip and mirror it in-place
  Compound operators (+=, -=, *=, /= etc) can be used in expressions - LET b=a+=1 will add 1 to a and then assign the result to b
  MAT INTERP a(),b() TO c(),amount interpolates values of two similar arrays by a certain amount into a third array
  INTERP(start,end,amount) function interpolates between start and end by the amount (0 to 1)
  You can now use the {} characters to create comments inside a line
  Short-circuit boolean evaluation for numeric AND/OR speeds up condition testing
  BINV(n,m) and BREV(n,m) invert (or reverse the order of) m lower-order bits in n
  INPUT ERROR now takes an optional REPEAT keyword to re-do the INPUT when an error occurs
  64bit and 32bit builds display their bit-types on the title bar, along with FPS information
  You can now use the ";" character to repeat a keyword with new parameters - e.g, CLS 1;2;3;4;5;6;7 will issue 7 CLS with different colours
  64Bit-specific optimisations to many operations (mostly graphics, but memory filling and allocation too)
  Loading a program automatically changes the directory to the file's location (not for MERGE)
  A new, faster and more accurate quadratic bezier curve algorithm for the CURVE routine - demo "ultraviolet" looks a lot better
  Added the POLYLINE keyword - works as for POLYGON, but SpecBAS doesn't close the polygon
  Added array parameters for DRAW array() and DRAW TO array()
  Some nice animations to opening/closing of the editor windows
  Key buffering in the editor so that fast typing isn't lost
  New Splash-screen and startup sound :) The old one used to crash on NEW with small window sizes
  A totally new method of doing screen updates lets us get really smooth graphics, at any frame rate
  The ? symbol can now be used instead of PRINT
  Due to popular demand, LET is now optional - though you can still use it if you like
  Inline inc/dec/mul/div to LET - LET a+=10 to add 10 to a. Also for -=,*=,/= -and- %= (mod) ^= (power) &=,|=,~= (AND/OR/XOR)
  The editor now ignores font scaling for UI elements, looks better for non-square editor fonts
  DIM SPLIT can now split on multiple characters

Fixed:

  Line breaks inside strings now syntax highlights properly
  Fixed crash when an expression (such as GFX$ 5) causes an error during interpretion/optimisation.
  Fixed GFX$ should not be marked as an optimisable function.

  Highlight line extends to whole program line
  Fixed Cut/Copy of null selections
  Fixed out of bounds errors in listing display
  Fixed problems with hitting tab when hovering a number in DW
  Added MIN$ and MAX$ for string compares (same as MIN/MAX for numbers)
  Fixed slowdown on entering new lines in the editor
  Fixed erroneous error marker when executing an evaluation in the DW
  Fixed: TAB brings selected line up if there's a line already in the edit line, instead of refreshing the current line
  Fixed: GFX mode indicator no longer disappears when changing focus
  Fixed: Crash on pressing Enter when the edit line consists of only whitespace
  Fixed issue with IIF/IIF$ and string AND.
  Fixed crash with focused mouse moving out of the window
  Added graphics mode display region in DW
  Fixed scrollbars drawing on window 0 after error
  Fixed FN parsing crashing compiler thread
  Fixed Object Bank loading (unpacking Hex data overran the buffer)

  Labels now found properly with TAB.
  Fixed Undo for pasting, re-ordering and renumbering
  Fixed compiler issues during pasting
  Fixed renumber for non-existing lines

  Fix for Copy with two parameters (for older FPC compilers - Pandora/Pi mainly).
  Fix non-GL Linux build - needs GL headers or sound will crash... WTF?
  Fix GO TO selecting and deleting the final "O"

  A crash in the optimiser for certain multiplication operations
  IN no longer requires range brackets ("[ ]") for a single element range, such as a$ IN b$
  IN now checks multi-char strings against ranges, ie "21" iN "4321" returns 1 (True)
  An issue with CALL which caused a crash when used
  CONSTants when used in an IIF function caused problems

  Faster display updates in Linux versions
  PRINT and TEXT could cause a stack overflow in some circumstances
  INSERT$ added extra characters to the source string
  DIM works with a list of stringvars now, instead of just numvars
  EXECUTE and TOKEN$ no longer crash/error with an empty string
  Fixed filled circles - now small circles are the correct size/shape
  Fixed Filled polygons - a flawed algorithm gave innacuracies with very thin horizontal polygons
  DRAW now obeys OVER properly
  Inline operators now work on numeric arrays too
  Large (or very, very small) numbers not in scientific notation no longer crash SpecBAS
  CALL as part of an expression caused parameter errors when used in complex expressions
  END IF not working after ELSE in some circumstances

One and a half years between updates so... not so much :)

The new editor was a bitch though - and I've just found my first post-release showstopping bug! I'll get a new version 0.901 up later today.
