-HISTORY for Lua 5.1
-
-* Changes from version 5.0 to 5.1
- -------------------------------
- Language:
- + new module system.
- + new semantics for control variables of fors.
- + new semantics for setn/getn.
- + new syntax/semantics for varargs.
- + new long strings and comments.
- + new `mod' operator (`%')
- + new length operator #t
- + metatables for all types
- API:
- + new functions: lua_createtable, lua_get(set)field, lua_push(to)integer.
- + user supplies memory allocator (lua_open becomes lua_newstate).
- + luaopen_* functions must be called through Lua.
- Implementation:
- + new configuration scheme via luaconf.h.
- + incremental garbage collection.
- + better handling of end-of-line in the lexer.
- + fully reentrant parser (new Lua function `load')
- + better support for 64-bit machines.
- + native loadlib support for Mac OS X.
- + standard distribution in only one library (lualib.a merged into lua.a)
-
-* Changes from version 4.0 to 5.0
- -------------------------------
- Language:
- + lexical scoping.
- + Lua coroutines.
- + standard libraries now packaged in tables.
- + tags replaced by metatables and tag methods replaced by metamethods,
- stored in metatables.
- + proper tail calls.
- + each function can have its own global table, which can be shared.
- + new __newindex metamethod, called when we insert a new key into a table.
- + new block comments: --[[ ... ]].
- + new generic for.
- + new weak tables.
- + new boolean type.
- + new syntax "local function".
- + (f()) returns the first value returned by f.
- + {f()} fills a table with all values returned by f.
- + \n ignored in [[\n .
- + fixed and-or priorities.
- + more general syntax for function definition (e.g. function a.x.y:f()...end).
- + more general syntax for function calls (e.g. (print or write)(9)).
- + new functions (time/date, tmpfile, unpack, require, load*, etc.).
- API:
- + chunks are loaded by using lua_load; new luaL_loadfile and luaL_loadbuffer.
- + introduced lightweight userdata, a simple "void*" without a metatable.
- + new error handling protocol: the core no longer prints error messages;
- all errors are reported to the caller on the stack.
- + new lua_atpanic for host cleanup.
- + new, signal-safe, hook scheme.
- Implementation:
- + new license: MIT.
- + new, faster, register-based virtual machine.
- + support for external multithreading and coroutines.
- + new and consistent error message format.
- + the core no longer needs "stdio.h" for anything (except for a single
- use of sprintf to convert numbers to strings).
- + lua.c now runs the environment variable LUA_INIT, if present. It can
- be "@filename", to run a file, or the chunk itself.
- + support for user extensions in lua.c.
- sample implementation given for command line editing.
- + new dynamic loading library, active by default on several platforms.
- + safe garbage-collector metamethods.
- + precompiled bytecodes checked for integrity (secure binary dostring).
- + strings are fully aligned.
- + position capture in string.find.
- + read('*l') can read lines with embedded zeros.
-
-* Changes from version 3.2 to 4.0
- -------------------------------
- Language:
- + new "break" and "for" statements (both numerical and for tables).
- + uniform treatment of globals: globals are now stored in a Lua table.
- + improved error messages.
- + no more '$debug': full speed *and* full debug information.
- + new read form: read(N) for next N bytes.
- + general read patterns now deprecated.
- (still available with -DCOMPAT_READPATTERNS.)
- + all return values are passed as arguments for the last function
- (old semantics still available with -DLUA_COMPAT_ARGRET)
- + garbage collection tag methods for tables now deprecated.
- + there is now only one tag method for order.
- API:
- + New API: fully re-entrant, simpler, and more efficient.
- + New debug API.
- Implementation:
- + faster than ever: cleaner virtual machine and new hashing algorithm.
- + non-recursive garbage-collector algorithm.
- + reduced memory usage for programs with many strings.
- + improved treatment for memory allocation errors.
- + improved support for 16-bit machines (we hope).
- + code now compiles unmodified as both ANSI C and C++.
- + numbers in bases other than 10 are converted using strtoul.
- + new -f option in Lua to support #! scripts.
- + luac can now combine text and binaries.
-
-* Changes from version 3.1 to 3.2
- -------------------------------
- + redirected all output in Lua's core to _ERRORMESSAGE and _ALERT.
- + increased limit on the number of constants and globals per function
- (from 2^16 to 2^24).
- + debugging info (lua_debug and hooks) moved into lua_state and new API
- functions provided to get and set this info.
- + new debug lib gives full debugging access within Lua.
- + new table functions "foreachi", "sort", "tinsert", "tremove", "getn".
- + new io functions "flush", "seek".
-
-* Changes from version 3.0 to 3.1
- -------------------------------
- + NEW FEATURE: anonymous functions with closures (via "upvalues").
- + new syntax:
- - local variables in chunks.
- - better scope control with DO block END.
- - constructors can now be also written: { record-part; list-part }.
- - more general syntax for function calls and lvalues, e.g.:
- f(x).y=1
- o:f(x,y):g(z)
- f"string" is sugar for f("string")
- + strings may now contain arbitrary binary data (e.g., embedded zeros).
- + major code re-organization and clean-up; reduced module interdependecies.
- + no arbitrary limits on the total number of constants and globals.
- + support for multiple global contexts.
- + better syntax error messages.
- + new traversal functions "foreach" and "foreachvar".
- + the default for numbers is now double.
- changing it to use floats or longs is easy.
- + complete debug information stored in pre-compiled chunks.
- + sample interpreter now prompts user when run interactively, and also
- handles control-C interruptions gracefully.
-
-* Changes from version 2.5 to 3.0
- -------------------------------
- + NEW CONCEPT: "tag methods".
- Tag methods replace fallbacks as the meta-mechanism for extending the
- semantics of Lua. Whereas fallbacks had a global nature, tag methods
- work on objects having the same tag (e.g., groups of tables).
- Existing code that uses fallbacks should work without change.
- + new, general syntax for constructors {[exp] = exp, ... }.
- + support for handling variable number of arguments in functions (varargs).
- + support for conditional compilation ($if ... $else ... $end).
- + cleaner semantics in API simplifies host code.
- + better support for writing libraries (auxlib.h).
- + better type checking and error messages in the standard library.
- + luac can now also undump.
-
-* Changes from version 2.4 to 2.5
- -------------------------------
- + io and string libraries are now based on pattern matching;
- the old libraries are still available for compatibility
- + dofile and dostring can now return values (via return statement)
- + better support for 16- and 64-bit machines
- + expanded documentation, with more examples
-
-* Changes from version 2.2 to 2.4
- -------------------------------
- + external compiler creates portable binary files that can be loaded faster
- + interface for debugging and profiling
- + new "getglobal" fallback
- + new functions for handling references to Lua objects
- + new functions in standard lib
- + only one copy of each string is stored
- + expanded documentation, with more examples
-
-* Changes from version 2.1 to 2.2
- -------------------------------
- + functions now may be declared with any "lvalue" as a name
- + garbage collection of functions
- + support for pipes
-
-* Changes from version 1.1 to 2.1
- -------------------------------
- + object-oriented support
- + fallbacks
- + simplified syntax for tables
- + many internal improvements

-INSTALL for Lua 5.1
-
-* Building Lua
- ------------
- Lua is built in the src directory, but the build process can be
- controlled from the top-level Makefile.
-
- Building Lua on Unix systems should be very easy. First do "make" and
- see if your platform is listed. If so, just do "make xxx", where xxx
- is your platform name. The platforms currently supported are:
- aix ansi bsd freebsd generic linux macosx mingw posix solaris
-
- If your platform is not listed, try the closest one or posix, generic,
- ansi, in this order.
-
- See below for customization instructions and for instructions on how
- to build with other Windows compilers.
-
- If you want to check that Lua has been built correctly, do "make test"
- after building Lua. Also, have a look at the example programs in test.
-
-* Installing Lua
- --------------
- Once you have built Lua, you may want to install it in an official
- place in your system. In this case, do "make install". The official
- place and the way to install files are defined in Makefile. You must
- have the right permissions to install files.
-
- If you want to build and install Lua in one step, do "make xxx install",
- where xxx is your platform name.
-
- If you want to install Lua locally, then do "make local". This will
- create directories bin, include, lib, man, and install Lua there as
- follows:
-
- bin: lua luac
- include: lua.h luaconf.h lualib.h lauxlib.h lua.hpp
- lib: liblua.a
- man/man1: lua.1 luac.1
-
- These are the only directories you need for development.
-
- There are man pages for lua and luac, in both nroff and html, and a
- reference manual in html in doc, some sample code in test, and some
- useful stuff in etc. You don't need these directories for development.
-
- If you want to install Lua locally, but in some other directory, do
- "make install INSTALL_TOP=xxx", where xxx is your chosen directory.
-
- See below for instructions for Windows and other systems.
-
-* Customization
- -------------
- Three things can be customized by editing a file:
- - Where and how to install Lua -- edit Makefile.
- - How to build Lua -- edit src/Makefile.
- - Lua features -- edit src/luaconf.h.
-
- You don't actually need to edit the Makefiles because you may set the
- relevant variables when invoking make.
-
- On the other hand, if you need to select some Lua features, you'll need
- to edit src/luaconf.h. The edited file will be the one installed, and
- it will be used by any Lua clients that you build, to ensure consistency.
-
- We strongly recommend that you enable dynamic loading. This is done
- automatically for all platforms listed above that have this feature
- (and also Windows). See src/luaconf.h and also src/Makefile.
-
-* Building Lua for QNX from Windows
- ---------------------------------
- Run cmd.exe and execute the following commands:
- > cd [bbndk] where [bbndk] is where the QNX NDK was installed (i.e. C:\bbndk)
- > bbndk-env.bat
- > cd [lua]/qnx where [lua] is the directory where Lua was extracted to
- > make
- Following this, the relevant binaries should reside in the following subdirectories:
- liblua:
- [lua]/qnx/arm/a.le.v7 (ARM release)
- [lua]/qnx/arm/a.le.v7.g (ARM debug)
- [lua]/qnx/x86/a (x86 simulator release)
- [lua]/qnx/x86/a.g (x86 simulator debug)
-
-* Building Lua on Windows and other systems
- -----------------------------------------
- If you're not using the usual Unix tools, then the instructions for
- building Lua depend on the compiler you use. You'll need to create
- projects (or whatever your compiler uses) for building the library,
- the interpreter, and the compiler, as follows:
-
- library: lapi.c lcode.c ldebug.c ldo.c ldump.c lfunc.c lgc.c llex.c
- lmem.c lobject.c lopcodes.c lparser.c lstate.c lstring.c
- ltable.c ltm.c lundump.c lvm.c lzio.c
- lauxlib.c lbaselib.c ldblib.c liolib.c lmathlib.c loslib.c
- ltablib.c lstrlib.c loadlib.c linit.c
-
- interpreter: library, lua.c
-
- compiler: library, luac.c print.c
-
- If you use Visual Studio .NET, you can use etc/luavs.bat in its
- "Command Prompt".
-
- If all you want is to build the Lua interpreter, you may put all .c files
- in a single project, except for luac.c and print.c. Or just use etc/all.c.
-
- To use Lua as a library in your own programs, you'll need to know how to
- create and use libraries with your compiler.
-
- As mentioned above, you may edit luaconf.h to select some features before
- building Lua.

-<B>lua</B>
-is the stand-alone Lua interpreter.
-It loads and executes Lua programs,
-either in textual source form or
-in precompiled binary form.
-(Precompiled binaries are output by
-<B>luac</B>,
-the Lua compiler.)
-<B>lua</B>
-can be used as a batch interpreter and also interactively.
-<P>
-The given
-<I>options</I>
-(see below)
-are executed and then
-the Lua program in file
-<I>script</I>
-is loaded and executed.
-The given
-<I>args</I>
-are available to
-<I>script</I>
-as strings in a global table named
-<B>arg</B>.
-If these arguments contain spaces or other characters special to the shell,
-then they should be quoted
-(but note that the quotes will be removed by the shell).
-The arguments in
-<B>arg</B>
-start at 0,
-which contains the string
-'<I>script</I>'.
-The index of the last argument is stored in
-<B>arg.n</B>.
-The arguments given in the command line before
-<I>script</I>,
-including the name of the interpreter,
-are available in negative indices in
-<B>arg</B>.
-<P>
-At the very start,
-before even handling the command line,
-<B>lua</B>
-executes the contents of the environment variable
-<B>LUA_INIT</B>,
-if it is defined.
-If the value of
-<B>LUA_INIT</B>
-is of the form
-'@<I>filename</I>',
-then
-<I>filename</I>
-is executed.
-Otherwise, the string is assumed to be a Lua statement and is executed.
-<P>
-Options start with
-<B>'-'</B>
-and are described below.
-You can use
-<B>'--'</B>
-to signal the end of options.
-<P>
-If no arguments are given,
-then
-<B>"-v -i"</B>
-is assumed when the standard input is a terminal;
-otherwise,
-<B>"-"</B>
-is assumed.
-<P>
-In interactive mode,
-<B>lua</B>
-prompts the user,
-reads lines from the standard input,
-and executes them as they are read.
-If a line does not contain a complete statement,
-then a secondary prompt is displayed and
-lines are read until a complete statement is formed or
-a syntax error is found.
-So, one way to interrupt the reading of an incomplete statement is
-to force a syntax error:
-adding a
-<B>';'</B>
-in the middle of a statement is a sure way of forcing a syntax error
-(except inside multiline strings and comments; these must be closed explicitly).
-If a line starts with

-then

-line. The expressions must be separated by commas.
-The primary prompt is the value of the global variable
-<B>_PROMPT</B>,
-if this value is a string;
