Standard Libraries

This sections gives an overview of the implementation state of the lua system libraries.

Basic library

• assert Calls System.Diagnostics.Debug.Assert.
• collectgarbage Only the parameter "count" and "collect" are supported. "step" and "isrunning" return always "true". "setpause" returns "false". "* dofile Redirects to DoChunk to load and run a text file. Optional add parameters for the script.

dofile('test.lua', 'a', 1, 'b', 2);

stdin is not supported."

• dochunk Redirects to DoChunk.
• error Throws a {{LuaRuntimeException}}.
• _G
• getmetatable No metatable for userdata, operators are used.
• ipairs
• load The "mode" "b" is not supported.
• loadfile The "mode" "b" is not supported.
• next
• pairs
• pcall
• print Prints on the debug output.
• rawequal
• rawget
• rawlen
• rawset
• select
• setmetatable No metatable for userdata, operators are used.
• tonumber
• tostring
• type “type” is extended with a second boolean parameter, that replaces “userdata” with the clr-type-name: type(obj, true);
• _VERSION
• xpcall

Coroutine library (coroutine)

Coroutines are implemented in the LuaThread class. This class creates a managed thread for every coroutine. The resume-steps can run asynchronous.

• create
• resume
• running
• status
• wrap
• yield
• :BeginResume Starts the execution of the next part of the thread.
• :EndResume Waits for the end of currently running part.

Package library (package)

• require Different implementation, that fits better with the NeoLua framework.
• config
• cpath
• loaded
• loadlib
• path
• preload
• searchers
• searchpath

String manipulation (string)

• byte
• char
• dump
• find .net regex syntax with an exchange of the escape symbol % is . But you can set string.__TranslateRegEx to false to use .net regulare expressions.
• format
• gmatch .net regex syntax with an exchange of the escape symbol % is . But you can set string.__TranslateRegEx to false to use .net regulare expressions.
• gsub .net regex syntax with an exchange of the escape symbol % is . But you can set string.__TranslateRegEx to false to use .net regulare expressions.
• len
• lower
• match
• pack
• packsize
• rep
• reverse
• sub
• unpack
• upper

Table manipulation (table)

• concat
• insert
• move
• pack
• remove
• sort
• unpack

Mathematical functions (math)

• abs
• acos
• asin
• atan
• atan2
• ceil
• cos
• cosh
• deg
• e
• exp
• floar
• fmod
• frexp
• huge
• ldexp
• log
• max
• maxinteger
• min
• mininteger
• modf
• pi
• pow
• rad
• random
• randomseed
• sin
• sinh
• sqrt
• tan
• tanh
• tointeger
• type

Bitwise operations (bit32)

• arshift
• band
• bnot
• bor
• btest
• bxor
• extract
• replace
• lrotate
• lshift
• rrotate
• rshift

Input and output (io)

"Works only with ASCII files. The file-handle uses the IDisposable-Pattern."

• close
• flush
• input
• lines
• open
• output
• popen
• read
• tmpfile
• tmpfilenew Creates a temporary file, that is deleted, when it is closed.
• type
• write
• :close
• :flush
• :lines
• :read
• :seek
• :setvbuf Ignored.
• :write

Operating system facilities (os)

• clock Returns TotalProcessorTime in seconds.
• date
• difftime
• execute On windows is no signal-result.
• exit
• getenv
• remove
• rename
• setlocale
• time
• tmpname

Debug facilities (debug)

• debug
• getuservalue
• gethook
• getinfo
• getlocal
• getmetatable
• getregistry
• getupvalue Works on closures and classes.
• setuservalue
• sethook
• setlocal
• setmetatable
• setupvalue Works on closures and classes.
• traceback
• upvalueid Do not trust the returned integer. The return value is only good for comparison.
• upvaluejoin Only works on closures (Lambda's). For example, the upvalues of the function that is returned by load are not join-able.
