v2.0-a086-80cc1eb

24 Jan 2018, 05:35

v2.0-a086-80cc1eb

Fixed methods [broken by v2.0-a085].
Changed `::: in a hotstring to escape only one colon, not two.
Changed hotstrings to split at the first ::, not the last. Note that with an odd number of consecutive colons, the previous behaviour did not consider the final colon as part of a pair. For example, ::1:::a included colon in the replacement while ::2::::b included double-colon in the trigger.

v2.0-a087-e4a5493

27 Jan 2018, 21:20

Changes to ([{ continuation:

Fixed detection of missing close-quote in continuation expressions.
Fixed comment sections and line continuation in or following ([{ continuation.
Fixed ([{ continuation for hotkeys with same-line action.
Fixed ([{ continuation for #If.

Changed ([{ continuation to allow continuation sections. The original intention was consistency between ( and [/{, but it didn't work out since continuation sections are handled before ([{ continuation (so were already "permitted" up to the first ([{-unbalanced line).

Improved detection of OTB vs. {} line continuation. It should now be smart enough to allow line continuation wherever an object literal is valid but OTB is not (except for While/If {, which are [still] treated as errors due to the missing parameter).

Other changes:

Improved continuation sections to automatically escape quotes if the continuation section is inside a quoted string, and not escape them otherwise. Removed the Quotes option.

Changed continuation sections to add space if first line ends with word.

Revised handling of xxx() where xxx is a control flow statement name.
  • All control flow statements allow () around their parameter list.
  • If at the start of a line, it is never a function call/definition.
Removed #IfWin and optimized #If Win().

Other bug fixes:

Fixed directives to not permit a comma after the directive name. The comma was treated as part of the parameter's value in most cases.
Fixed quotes being put around vars in ListLines/error text.
Fixed Hotkey() to throw correctly when it fails.
Fixed Hotkey() to allow Label to be omitted.

v2.0-a089-3de22ab

18 Feb 2018, 06:02

Fixed WinGetClientPos to return size, not bottom-right position.
Fixed unary operators following an empty parameter.
Merged v1.1.28.00.
Made A_ListLines writable.
Fixed properties like "x{" and "xx{" in class definitions.
Changed stdin (*) scripts to not prepend working dir to title or A_ScriptFullPath.
Changed threads to execute minimum one line before first interruption.
Changed default thread uninterruptibility to 17ms. Anything less can be virtually no time at all since GetTickCount() has a granularity of 15 or 16.
Removed Suspend("Permit") and added #SuspendExempt.
Removed obsolete checks for action type of thread's first line.
Fixed some issues with #If [broken by v2.0-a087].
Changed remapping to release mandatory modifiers, such as for ^a::b.

v2.0-a090-ae96c4a

26 Mar 2018, 05:25

Added nested functions, closures and fat arrow => functions.

Renamed RegisterCallback to CallbackCreate and changed to better utilize closures:
  • Added support for function objects.
  • Removed EventInfo parameter (use a closure or bound function instead).
  • Removed the special behaviour of variadic callback functions and added the & option (pass the address of the parameter list).
  • Added CallbackFree(Address), to free the callback memory and release the associated function object.
Changed IsFunc() and Func() to require a function name. Passing an object is now an error.

It is no longer possible to externally call a subroutine inside a function (local label). Nested functions provide the same benefits without the limitations. Specifically:
  • Changed SetTimer and Menu.Add to use only functions/objects, not labels.
  • Changed Hotkey and Hotstring to ignore local labels.
Improved handling of trailing blank parameters.

Optimized Func("LiteralName") to resolve the function name at load time (only applies to direct calls with a single plain quoted string).

Fixed the new Hotstring() function.

v2.0-a091-9baa9fa

30 Mar 2018, 23:30

Added the capability to name fat arrow functions. This also fixes crashes caused by previously invalid code like MsgBox() => expr.

Fixed => on a line following a label/hotkey/hotstring.
Fixed multi-level upvars (locals from outer-outer function).
Fixed := operator within a fat arrow function.
Fixed => in static class var initializers to not have an implicit this parameter.
Fixed => below if/else/loop/try/etc. to work without a block.
Debugger: Fixed stepping over return after a nested function.

Implemented some trivial optimizations to string key lookup and linear array indexing in objects.
Fixed () => x ? y := v : z.
Removed UseErrorLevel from Run/RunWait.
Changed Run/RunWait to always set A_LastError.
Converted RunWait, ClipWait, KeyWait and WinWait' to functions.
  • Never set ErrorLevel.
  • Return non-zero if condition was met (zero for timeout).

  • WinWaitClose: set Last Found Window.
Changed math functions and operators to throw an exception instead of returning "" for errors.
Added type-conversion functions Float, Integer and String.

Removed File.Tell().
Replaced SendRaw/ControlSendRaw with SendText/ControlSendText.
Changed hotstrings with continuation sections to use {Text} vs. {Raw}.

v2.0-a100-52515e2

05 Oct 2018, 22:52

Merge pull request #111 from HelgeffegleH/AutoHotkey_L (validation of A_CoordMode).
Changed A_CoordMode to require a non-empty value on assignment.
Changed ComObjValue() and ComObjFlags() to require a valid ComObject.
Changed Func.IsOptional(n) and Func.IsByRef(n) to throw if n is invalid.
Changed usage of Control parameter with Control functions and SendMessage/PostMessage.
  • Can be a HWND (integer)
  • Can be an object with a HWND property
  • Mandatory in most cases
  • Omit to use target window itself (ahk_parent is removed)
  • Blank values are invalid (never default to topmost control)
Added ControlGetClassNN().
Changed ControlGetFocus() to return a HWND.
Changed "Script file not found" to respect /ErrorStdOut and exit code.
Replaced A_IPAddressX with SysGetIPAddresses().
Changed * (stdin) scripts to use A_InitialWorkingDir as A_ScriptDir.
Changed StrPut and StrGet to throw on failure, not return "" or 0.
Updated ImageSearch, PixelSearch and PixelGetColor.
  • ImageSearch and PixelSearch: return true if found.
  • Throw an exception on failure.
  • Do not set ErrorLevel.
Changed PixelSearch to default to Fast mode; added Slow option.

Fixed 64-bit keys in the debugger on 32-bit builds.
Fixed reliability of object keys on 32-bit builds.
Fixed __init/__delete causing misleading error line/stack trace.
Fixed hotkey-related crashes caused by erroneous ZeroMemory call.

Note: Specifying a window (WinTitle) by HWND still requires ahk_id for now. WinTitle will get similar treatment to Control in a future update.
