Smalltalk/X jv-branch ChangeLog

• 2017-06-06
  • ENH: Added support for reading / setting Unix TTY / PTY attributes (tcgetatr() / tcsetattr()). For details, see ​d58698c455c1/stx.libbasic

• 2017-05-29
  • ENH: Major cleanup and refactoring of keyboard mapping to allow applications to define their own shortcuts (so far shortcuts definition was sort-of-global). As a side effect, shortcut definition has been cleaned up and support for national languages in X11 has been significantly improved (not it works for most languages out of the box. no need to customize keymapping to map from X11 keysym to a characrer. XIC still yet to be implemented). For details, see:
    • 2bac4f32553f/stx.libview: Allow individual applications to define their own shortcut mapping
    • 43c6888f5f92/stx.libview: Changed shortcut labels in menus to always show uppercase letters
    • 8bbd397fe321/stx.libview: Keyboard mapping: refactored KeyboardMap to distinguish between a binding and an alias(es)

    • c7cab63f9ec9/stx.libview: X11: translate national characters early in X11 event processing
    • b7688f8c4d7a/stx.libtool: Keyboard mapping: code updated to catch up with KeyboardMap
    • c03e750ffe41/stx.libwidg2: Align shortcuts in menus to the right
    • 9ff89d98ba80/stx.libwidg2: Keyboard mapping: code updated to catch up with KeyboardMap

• 2016-02-18
  • ENH: In STC generated code, always refer class object using __STX_SomeClass instead of just SomeClass, i.e., use __STX_ prefix. This allow to #undef SomeClass in case it clashes with included definitions.

  • FIX: Fixed bug in LargeInteger literals in stc-compiled code.

• 2015-10-04

  • stx:libbasic
    • ENH: Performance fixes in String>>at: and Array>>at:/at:put: - see 877a8f1b326d/stx.libbasic and 9e4db770f8f5/stx.libbasic

  • Virtual machine
    • ENH: Use mmap() / munmap() to allocate new space.
