This is something I was always missing - posibbility to operate on
binary files or streams in pure lua. In most cases we do only need to
read simple variables from files such as integers with different amount
of bytes. This "class" will provide that ability.
It's a simple implementation of following C module for lua:
http://www.inf.puc-rio.br/~roberto/struct/
It has much less, though. Following elements have been implemented:
">" flag to set mode to big endian.
"<" flag to set mode to little endian.
"b" a signed char.
"B" an unsigned char.
"h" a signed short (2 bytes).
"H" an unsigned short (2 bytes).
"i" a signed int (4 bytes).
"I" an unsigned int (4 bytes).
"l" a signed long (8 bytes).
"L" an unsigned long (8 bytes).
"s" a zero-terminated string.
An example how to use it:
```lua
local packed = Struct.pack('<LIhBsb', 123456789123456789, 123456789,
-3200, 255, 'Test message', -1)
-- packed is now a lua string we can save to file as binary data
local L, I, h, B, s, b = Struct.unpack('<LIhBsb', packed)
print(L, I, h, B, s, b)
```
You can use g_resources.readFileContents as function to read binary
files and parse them via this class.
* Fixed NextButton and PreviousButton style
* Little update to SpinBox including dontSignal
* Market cleanup and more check to be safe
* Limit Market amountWindow by player balance
* Set proper maximum amount when creating offers
* Fixed fee label not calculating the correct fee sometimes
- Market now works after reloading
- Fixed button / tab styles
- MarketRightTabBarButton now inherits the base style
- Fixed amountWindow buttons being hardly clickable
- "All" search filter is now on by default
* Added better walk key binding (for other uses, like the sample given WASD).
* Made string.ends part of the string meta table rather than parameter based.
* Begin working on a new layout system for UIMinimap and later UIMap,
this new layout system allows to add widgets to the minimap
* Add option to disable motd
* Rework hotkey binding
* Lots of fixes in hotkeys manager
* Add fullmap view using Ctrl+Shift+M
* Prevent some crashs in ThingType draw
* Add function to load minimap from PNG files
* Fixes in minimap saving
* Fixes in Tile::isClickable
* Add UIMapAnchorLayout, new layout for maps
* Fix freezes in win32 when pressing alt key
