ec11c472c8 Various changes to bring pm.lua test closer to passing:
* New and complete character class support
 * string.gsub implemented
 * rawset implemented
 * lua_call added (based on lua_pcall)
 * lua_pop added
 * newCall removed; luaGetTable and luaSetTable in LFunction updated to
   use lua_call instead.
 * StandardTest changed to avoid an ArrayIndexOutOfBoundsException

Unfortunately I discovered a problem where execute() will loop around too
many times and call exec() with a call frame that has already completed.
This might be due to the lack of the "tailcalls" field in our CallInfo class
that the C version maintains?

fc8c790b0d Fixes for string.rep, string.byte, string.lower, and string.upper. Also
factor out negative index handling to separate function, posrelat (to
match C Lua). When converting numbers to strings, see if the double value
can be represented exactly as a long, and if so format the string as
an integer. With these changes the standard test case "strings.lua" runs
to line 104 (over half way through!), where it uses string.format.

bd6dd58a2d String related improvements:
(1) Fix string.char and string.byte (argument indexing was off by one)
(2) Implement string.find
(3) Change calls to charAt, which does array bounds checking, in the
    pattern matcher with calls to luaByte, which does not.
(4) Replace use of recursion with while/continue in pattern matcher.

534e69fcfb Add pattern matcher implementation ported from C version of Lua. Still
work to do:
(1) Replace use of recursion with while/continue
(2) Remove as many array bounds checks as possible

952a2f9f16 Add skeleton for string library calls. 2007-09-18 01:00:36 +00:00

6d0e9bb566 Add some helper methods:
(1) getKeys() in LTable is now public. It provides a convenient interface
    to access the table's elements from Java instead of Lua.
(2) LString.toInputStream produces an instance of InputStream from which
    the string's bytes can be read.

aeafca11b6 Change LString to use an array of bytes instead of wrapping Java's String.
This brings our implementation more in line with regular C Lua.

aa44eedf4b Allow metatable operations on values of all types, and use the metatable
on strings as the string package, so that string functions can be called
with self (:) syntax. Autoload test case now inexplicably fails more,
but it was already broken.

b8571b93f9 New implementation for Lua tables. Does not use Vector or Hashtable, instead
uses plain Java arrays directly to keep heap allocation to a minimum.
Includes some unit tests that seem to indicate the basic operations are
correct. However, the following things are not implemented:

* Shrinking the capacity when elements are removed
* Optimal storage of each element in array vs. hash when entries are
  added out of order. A junit test case is there for this.

b9fdb731fe optimization for tables that include sequential integral indices starting with 0.
commented out: a more sophisticated (but space-consuming) optimization
that accounts for arbitrary starting index, stride, and direction (increasing/decreasing).

commented out some table metatable stuff that was wrong.  metatables
need to be implemented properly.

8bf4c82a12 Rework the main API"s that implement the calling convention. Provide utility methods to get arguments that were supplied, and provide return values. Add a VM interface to clarify the relationship between the VM, things that call the VM, and things that are called by the VM. Make the code more closely aligned with the C++ version. 2007-07-24 05:06:10 +00:00

2a64db32b5 Add last Lua type: userdata. Changed LInstance to inherit from LUserData,
and changed instanceof/casts to LInstance to use LUserData instead. This
should enable various add-ons to be compatible without knowing much, or
anything, about each other.
