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 - -(end of HISTORY) -- cgit v1.2.3
