Added more Lua environment features
Package library:
* Added a simulation of the Lua 5.1 package library.
* Removed mw.import(), replaced it with a package loader. Packages can be
retrieved from the wiki, using require('Module:Foo'), or from files
distributed with Scribunto, using require('foo'). The "Module:" prefix allows
for source compatibility with existing Lua code.
* Added a couple of libraries from LuaForge: luabit and stringtools.
* Made fetchModuleFromParser() return null on error instead of throwing an
exception, to more easily support the desired behaviour of the package loader,
which needs to return null on error.
* Renamed mw.setupEnvironment() to mw.setup() since it is setting up things
other than the environment now.
* In MWServer:handleRegisterLibrary(), remove the feature which interprets dots
in library names, since LuaSandbox doesn't support this.
Improved module isolation and related refactoring:
* Expose restricted versions of getfenv() and setfenv() to user Lua code.
Requires luasandbox r114952.
* Don't cache the export list returned by module execution for later function
calls. This breaks isolation of #invoke calls, since the local variables are
persistent.
* Removed ScribuntoFunctionBase and its children, since it doesn't really have
a purpose if it can't cache anything. Instead, invoke functions using a module
method called invoke().
* Removed Module::initialize(), replaced it with a validate() function. This is
a more elegant interface and works better with the new module caching scheme.
* Use a Status object for the return value of Engine::validate() instead of an
array. Use the formatting facilities of the Status class.
Other:
* Removed "too many returns" error, doesn't fit in with Lua conventions.
* Use the standalone engine by default, so that the extension will work without
configuration for more people.
* Added an accessor for $engine->interpreter
* Fix mw.clone() to correctly clone metatables
* If the standalone interpreter exits due to an error, there are some contexts
where the initial error will be caught and ignored, and the user will see the
error from checkValid() instead. In this case, rethrow the original error for
a more informative message.
* Load mw.lua into the initial standalone environment, to reduce code
duplication between mw.lua and MWServer.lua.
* Fixed a bug in Scribunto_LuaStandaloneInterpreter::handleCall() for functions
that return no results.
* Fixed a bug in encodeLuaVar() for strings with "\r". Added test case.
* In MWServer.lua, don't call error() for internal errors, instead just print
the error and exit. This avoids a protocol violation when an error is
encountered from within handleCall().
* Added lots of documentation. Lua doc comments are in LuaDoc format.

LuaBit
|
|
|
|
|
------
|
|
|
|
|
LuaBit is a bitwise operation lib completely written in Lua. It's
|
|
|
|
|
written in the belief that Lua is self-contained.
|
|
|
|
|
|
|
|
|
|
The supported operations are: not, and, or, xor, right shift, logic
|
|
|
|
|
right shift and left shift.
|
|
|
|
|
|
|
|
|
|
Several utilities are designed to leverage the power of bit operation:
|
|
|
|
|
1. hex: a dec <-> hex number converter
|
|
|
|
|
2. utf8: convert utf8 string to ucs2
|
|
|
|
|
3. noki: convert nokia pc suite backuped SMS file to .txt
|
|

LuaBit. You can require 'hex' to use them:
|
|
|
|
|
hex.to_hex(n) -- convert a number to a hex string
|
|
|
|
|
hex.to_dec(hex) -- convert a hex string(prefix with '0x' or '0X') to number
|
|
|
|
|
|
|
|
|
|
With hex, you can write code like:
|
|
|
|
|
bit.band(258, hex.to_dec('0xFF'))
|
|
|
|
|
to get the lower 8 bits of 258, that's 2.

-------

|
|
|
|
v0.4
|
|
|
|
|
* utf8 to ucs2 converter(utf8.lua).
|
|
|
|
|
* clean up for compatible with Lua5.1 and 5.0.
|
|
|
|
|
* add 'How to use' section for bit.lua and hex.lua.
|
|
|
|
|
|
|
|
|
|
v0.3
|
|
|
|
|
* noki added as an application of bit.

|
* typo correction.
|

|
|
v0.2
|
|
|
|
|
* add logic right shift(>>>) support: bit.blogic_rshift.
|
|
|
|
|
* add 2 utility functions: bit.tobits and bit.tonumb.
|
|
|
|
|
* update hex.to_hex(in hex.lua) to support negative number.

LuaBit is written when I do my own game project(Fio at http://fio.edithis.info).

Added more Lua environment features
Package library:
* Added a simulation of the Lua 5.1 package library.
* Removed mw.import(), replaced it with a package loader. Packages can be
retrieved from the wiki, using require('Module:Foo'), or from files
distributed with Scribunto, using require('foo'). The "Module:" prefix allows
for source compatibility with existing Lua code.
* Added a couple of libraries from LuaForge: luabit and stringtools.
* Made fetchModuleFromParser() return null on error instead of throwing an
exception, to more easily support the desired behaviour of the package loader,
which needs to return null on error.
* Renamed mw.setupEnvironment() to mw.setup() since it is setting up things
other than the environment now.
* In MWServer:handleRegisterLibrary(), remove the feature which interprets dots
in library names, since LuaSandbox doesn't support this.
Improved module isolation and related refactoring:
* Expose restricted versions of getfenv() and setfenv() to user Lua code.
Requires luasandbox r114952.
* Don't cache the export list returned by module execution for later function
calls. This breaks isolation of #invoke calls, since the local variables are
persistent.
* Removed ScribuntoFunctionBase and its children, since it doesn't really have
a purpose if it can't cache anything. Instead, invoke functions using a module
method called invoke().
* Removed Module::initialize(), replaced it with a validate() function. This is
a more elegant interface and works better with the new module caching scheme.
* Use a Status object for the return value of Engine::validate() instead of an
array. Use the formatting facilities of the Status class.
Other:
* Removed "too many returns" error, doesn't fit in with Lua conventions.
* Use the standalone engine by default, so that the extension will work without
configuration for more people.
* Added an accessor for $engine->interpreter
* Fix mw.clone() to correctly clone metatables
* If the standalone interpreter exits due to an error, there are some contexts
where the initial error will be caught and ignored, and the user will see the
error from checkValid() instead. In this case, rethrow the original error for
a more informative message.
* Load mw.lua into the initial standalone environment, to reduce code
duplication between mw.lua and MWServer.lua.
* Fixed a bug in Scribunto_LuaStandaloneInterpreter::handleCall() for functions
that return no results.
* Fixed a bug in encodeLuaVar() for strings with "\r". Added test case.
* In MWServer.lua, don't call error() for internal errors, instead just print
the error and exit. This avoids a protocol violation when an error is
encountered from within handleCall().
* Added lots of documentation. Lua doc comments are in LuaDoc format.

When loading resources, I have to do some bit operation. And I do not
|
|
|
|
|
like the embedded way of bit operation. So I decide to implement those
|
|
|
|
|
ops in lua. And that's LuaBit. It's not as fast as the embedded one, but
|
|
|
|
|
it works. And Lua is self-contained :-)

It'll be useful if LuaBit support those bitwise op like:

bit.band(258, '0xFF')
|
|
|
|
|
ease to type and use. This will be supported in next release.

May more utility functions add to Noki - phonebook might be a nice candidate.

There's no UCS2 -> UTF8 convertion now, this feature may add in next release

or when the project need.

into a powerful tool to support more Nokia PC Suite backup format(.nfb,

though the bit sequence is correct. So if you want do some arithmetic with

the result of bit operation, be careful.
