Lablua is a research lab at PUC-Rio, affiliated with its\ Computer Science Department. It is dedicated to research\ about programming languages, with emphasis on research involving the Lua\ language. Lablua was founded on May 2004 by Prof. Roberto Ierusalimschy.\ Since then its members have produced one PhD thesis and two MSc dissertations.
\ \Lua is a scripting language not totally unlike Tcl, Perl, or Python. Like Tcl, Lua is an \"embedded language\", in the sense that embedding the interpreter into your program is a trivial task, and it is very easy to interface Lua with other languages like C, C++, or even Fortran. Like Python, Lua has a clear and intuitive syntax. Like all those three, Lua is an interpreted language with dynamic typing, and with several reflexive facilities.
\ \In these pages you can find information about current and past projects, publications and members. Please\ follow the links above to go to the other sections of the web site.
\ \Lablua is situated at PUC-Rio's campus, near the Cardeal Leme building. Prof. Ierusalimschy's contact\ information is in his web page. You can also contact\ Lablua by phone: 55-21-3527-1497 Ext. 4523.

\ \ \
\
The decompiler performs two passes. The first pass is considered a \"preliminary\
pass\". Only two actions are performed: addresses of backward jumps are gathered\
for while constructs, and variables referenced by CLOSE\
\
instructions are taken note of in order to identify the point where explicit\
do blocks should be opened.\
\ The actual decompilation takes place in the second, \"main pass\". In this pass,\ the instructions are symbolically interpreted. As functions are traversed\ recursively, the symbolic content of registers are kept track of, as well as\ a few additional data structures: two register stacks, one for \"variable\ registers\" (registers currently allocated for variables) one for \"temporary\ registers\" (registers holding temporary values); and a list of boolean conditions. \
\\
Instructions like ADD and MOVE combine the string\
representation of symbols and move them around in registers. Emission of actual\
statements is delayed until the temporaries stack is empty, so that constructs\
like a,b=b,a are processed correctly. \
\
\
The list of boolean conditions accumulate pairs of relational operators (or\
TESTs and jumps). The translation of a list into a boolean expression\
is done in three stages. In the first stage, jump addresses are checked to identify\
\"then\" and \"else\" addresses and to break the list into smaller lists in the case of\
nested if statements. In the second stage, the relations between the\
jumps is analyzed serially to devise a parenthization scheme. In the third scheme,\
taking into account the parenthization and an 'inversion' flag (used to tell\
\"jump-if-true\" from \"jump-if-false\" expressions), the expression is printed,\
recursively.\
\
Two forms of \"backpatching\" are used in the main processing pass: boolean conditions\
for while constructs are inserted in the marked addresses (as noted in\
the first pass), and do blocks are added as necessary, according to the\
liveness information of local variables.\
\
LuaDec is written by Hisham Muhammad, and is licensed\ under the same terms as Lua. Windows binaries contributed by Fabio Mascarenhas.
\ \\ LuaDec, in its current form, is not a complete decompiler. It does\ succeed in decompiling most of the Lua constructs, so it could be used as\ a tool to aid in retrieving lost sources.\
\ \\
The situations where LuaDec \"get it wrong\" are usually related to deciding\
whether a sequence of relational constructs including TEST operators\
are part of an assignment or an if construct. Also, the \"single pass\"\
nature of the symbolic interpreter fails at some corner cases where there simply\
is not enough information in the sequence of operator/jump pairs to identify what\
are the \"then\" and \"else\" addresses. This is an example of such a case:\
\ 1 [2] LOADNIL 0 2 0\ 2 [3] JMP 0 16 ; to 19\ 3 [4] EQ 0 1 250 ; - 2\ 4 [4] JMP 0 2 ; to 7\ 5 [4] TEST 2 2 1\ 6 [4] JMP 0 5 ; to 12\ 7 [4] EQ 0 1 251 ; - 3\ 8 [4] JMP 0 3 ; to 12\ 9 [4] LOADK 3 2 ; 1\ 10 [4] TEST 3 3 1\ 11 [4] JMP 0 0 ; to 12\ 12 [6] LOADK 0 2 ; 1\ 13 [7] JMP 0 7 ; to 21\ 14 [8] LOADK 0 0 ; 2\ 15 [8] JMP 0 3 ; to 19\ 16 [10] LOADK 0 1 ; 3\ 17 [11] JMP 0 3 ; to 21\ 18 [12] LOADK 0 4 ; 4\ 19 [3] TEST 1 1 1\ 20 [3] JMP 0 -18 ; to 3\ 21 [14] RETURN 0 1 0\\ \
\
local a, x, y\
while x do\
if ((x==2) and y) or ((x==3) and 1) or 0\
\
then\
a = 1\
do break end\
a = 2\
else\
a = 3\
do break end\
a = 4\
end\
a = 5\
end\
\
\
\
Notice that there is no reference to the \"else\" address in the highlighted sequence.\
Only with a more sophisticated block analysis it would be possible to identify the\
varying purposes of the JMP instructions at addresses 13, 15 and 17.\

\
LuaDec includes a -d flag, which displays the progress\
of the symbolic interpretation: for each bytecode, the variable stacks\
and the code generated so far are shown.\
\ In its default operation mode, LuaDec recursively processes the program functions,\ starting from the outmost chunk (\"main\"). When LuaDec detects a decompilation error\ (by doing sanity checks on its internal data structures), Luadec outputs the portion\ of the function decompiled so far, and resumes decompilation in the outer closure.\
\ \\
There is an alternative operation mode, set with the -f flag,\
where all functions are decompiled separately. This does not generate a .lua file\
structured like the original program, but it is useful in the cases where a\
decompilation error makes a closure declaration \"unreachable\" in the default\
operation mode. This allows a larger portion of the sources to be restored in\
the event of errors.\

\ \ \What sets Lua apart from those languages is its portability, simplicity, and small size. \ Lua is written in ANSI C, and runs without modifications in almost any platform (MS-DOS, \ all versions of Windows, all flavors of Unix, plus X-Box, PlayStation II, OS/2, BeOS, \ EPOC, etc.). The whole program lua.exe has less than 200 Kbytes. Its simplicity led other \ groups to adopt Lua as a scripting language for other scripting languages (see, for \ instance, Ruby-Lua).
\ \Currently, Lua has a strong presence whenever programmers need a light, efficient,\ and portable language. It is being used by some tens of thousands programmers around \ the world, both in research and in industrial projects. Lua has been successfully \ used in games (e.g. Grim Fandango, Escape from Monkey Island, MK2, Baldur's Gate), \ in robots (e.g. Crazy Ivan, that won the Danish RoboCup in 2000 and 2001), and \ several other applications (e.g. a hot-swappable Ethernet switch (CPC4400), a genetic \ sequence visualization system (GUPPY), \"The most Linux on one floppy disk\" (tomsrtbt)). \ An extended list of applications using Lua can be found \ here.
\ \The Lua.NET project integrates Lua with the \ Common Language Infrastructure,\ a framework for language interoperability. \ This integration allows Lua \ to act both as a \"client\" language and as a \"server\" language, although with a\ limited capacity for the latter. As a client, Lua scripts can access components available \ through the CLI. As a server, Lua scripts can implement new components accessible by \ other languages integrated with the CLI.
\ \
Because Lua is an interpreted language with dynamic typing, its integration with \ the CLI demands a dynamic nature. Lua.NET employs two approaches for this integration. \ The first uses the same techniques used to implement LuaOrb, \ a scripting tool that can access and implement CORBA, COM and Java \ components. The approach is implemented by the LuaInterface library.
\ \ \The second approach compiles Lua to the CLI's Common Intermediate \ Language, instead of its own bytecode representation. This approach is implemented\ by the Lua2IL compiler.
