# E-scripts on Lua.
#
# Note 1: use the eev command (defined in eev.el) and the
# ee alias (in my .zshrc) to execute parts of this file.
# Executing this file as a whole makes no sense.
# An introduction to eev can be found here:
#
# (find-eev-quick-intro)
# http://angg.twu.net/eev-intros/find-eev-quick-intro.html
#
# Note 2: be VERY careful and make sure you understand what
# you're doing.
#
# Note 3: If you use a shell other than zsh things like |&
# and the for loops may not work.
#
# Note 4: I always run as root.
#
# Note 5: some parts are too old and don't work anymore. Some
# never worked.
#
# Note 6: the definitions for the find-xxxfile commands are on my
# .emacs.
#
# Note 7: if you see a strange command check my .zshrc -- it may
# be defined there as a function or an alias.
#
# Note 8: the sections without dates are always older than the
# sections with dates.
#
# This file is at <http://angg.twu.net/e/lua5.e>

Before running any code, lua collects all command-line arguments in a
global table called arg. The script name goes to index 0, the first
argument after the script name goes to index 1, and so on. Any
arguments before the script name (that is, the interpreter name plus
its options) go to negative indices. For instance, in the call
$ lua -la b.lua t1 t2
the table is like this:
arg = { [-2] = "lua", [-1] = "-la",
[0] = "b.lua",
[1] = "t1", [2] = "t2" }
If there is no script in the call, the interpreter name goes to index
0, followed by the other arguments. For instance, the call
$ lua -e "print(arg[1])"
will print "-e". If there is a script, the script is called with
arguments arg[1], ..., arg[#arg]. (Like all chunks in Lua, the script
is compiled as a vararg function.)

x: (where x is not one of the magic characters ^$()%.[]*+-?)
represents the character x itself.
.: (a dot) represents all characters.
%a: represents all letters.
%c: represents all control characters.
%d: represents all digits.
%l: represents all lowercase letters.
%p: represents all punctuation characters.
%s: represents all space characters.
%u: represents all uppercase letters.
%w: represents all alphanumeric characters.
%x: represents all hexadecimal digits.
%z: represents the character with representation 0.
%x: (where x is any non-alphanumeric character) represents the
character x. This is the standard way to escape the magic
characters. Any punctuation character (even the non magic) can
be preceded by a '%' when used to represent itself in a pattern.
[set]: represents the class which is the union of all characters in
set. A range of characters can be specified by separating the
end characters of the range with a '-'. All classes %x described
above can also be used as components in set. All other
characters in set represent themselves. For example, [%w_] (or
[_%w]) represents all alphanumeric characters plus the
underscore, [0-7] represents the octal digits, and [0-7%l%-]
represents the octal digits plus the lowercase letters plus the
'-' character. The interaction between ranges and classes is not
defined. Therefore, patterns like [%a-z] or [a-%%] have no
meaning.
[^set]: represents the complement of set, where set is interpreted
as above. For all classes represented by single letters (%a, %c,
etc.), the corresponding uppercase letter represents the
complement of the class. ***For instance, %S represents all
non-space characters.***
The definitions of letter, space, and other character groups depend
on the current locale. In particular, the class [a-z] may not be
equivalent to %l.

The "arg" table is not discussed much in the reference manual for
lua-5.1... I haven't checked this very thoroughly, but I think that
"arg" is mentioned only at the "Incompatibilities with the Previous
Version" section.
For some reason people don't like the old idea of keeping the size of
an array at its ".n" field, and weird alternatives like having a
different kind of "nil" that is not seen as a "hole" pop up at the
mailing list all the time.
To do: find a link to some recent thread about these "alternative
nils" at the mailing list archive.
http://lua-users.org/lists/lua-l/
To do: replace the "unpack"s in the init file by "myunpack"s, and the
"return unpack(arg)"s by "return ..."s; also, check for 5.0-isms, and
and for old scripts still lying around that may still be lua-5.0
based.

i re-read Knuth over dinner last night. unfortunately, he is
discussing hashes where you store data elements right in the hash
table, and can then easily do linear probing [i heard that, you in the
second row]. i can't think of a good way to apply his double hashing
algorithm (algorithm D, p. 528) or Brent's variation (p. 532) to help
improve the hash function without using a multiplicative hash.

E. G. Mallach [Comp. J. 20 (1977), 137-140] has experimented with
refinements of Brent's variation, and further results have been
obtained by Gaston H. Gonnet and J. Ian Munro [SICOMP 8 (1979),
463-478].

<edrx> ok, I'm inspecting the disassembled bytecode for a lua script
to try to understand how a closure gets the name that is
displayed on tracebacks...
<Keffo> hmm, wtf is this.. http://www.ubuntu.org/
<Keffo> edrx: Why do you care? :)
<edrx> my only guess at the moment - if the disassembled bytecode
really shows everything that the bytecode has - is that
closures are born without names, and "setglobal" notice when
they are assigning unnamed closures to (named) variables and
set the name of the closure...
<edrx> but that seems a bit inneficient
<edrx> Keffo: I care because this is one of the two main things that I
don't understand about Lua and that I have to confess that I
don't know when I explian Lua to people or give talks about it
(I gave a few at free software events)

Add #ifdefs that activate the compatibily block of lauxlib.h.
Build the array "arg" before running the first "-e".
Allow things like ``while a=f() do ... end'', and maybe something
similar for `if' and `elseif' too.
Power patch: add a way to let the interpreter be a pointer to a
function instead of a fixed function
Power patch: add a keyword that when parsed interrupts the execution
of the interpreter, to let us examine its state
Power patch: create an interpreter that can be interrupted and resumed
Power patch: add a "tfunction" keyword that behaves like "function",
but if a certain global variable ("tfunctionfunction"?) exists it
invokes it just after building the bytecode for the function. For
example, in ``unnamedfunctions["3"] = tfunction return 1+2 end'' we
would have the call ``tfunctionfunction(bytecode, chunk, begpos,
endpos)'', where bytecode is the code for ``function return 1+2 end'',
chunk is the string from where that all came and begpos and endpos are
the positions of the ``tfunction return 1+2 end'' in the string. By
the way: the reason why I want such a beast (tfunction) is that I'd
like to keep a weak table with the source code of the ``user-defined
primitives'' in LForth, that are built from strings in complicated
way.

Idea: string.gsub(s, pat1, repl1,
pat2, repl2,
pat3, repl3, ...)
would, at each char, test the string "s" against pat1, pat2, ...; the
first one to match would be replaced - and, as usual, each repln is
either a string or a function.
That would be a cheap way to implement a simple form of "|".

This function returns a table with information about a function. You
can give the function directly, or you can give a number as the value
of function, which means the function running at level function of the
call stack: Level 0 is the current function (getinfo itself); level 1
is the function that called getinfo; and so on. If function is a
number larger than the number of active functions, then getinfo
returns nil.
The returned table contains all the fields returned by lua_getinfo,
with the string what describing which fields to fill in. The default
for what is to get all information available. If present, the option
`f' adds a field named func with the function itself.
For instance, the expression debug.getinfo(1,"n").name returns the
name of the current function, if a reasonable name can be found, and
debug.getinfo(print) returns a table with all available information
about the print function.
debug.getlocal (level, local)

Hi Kartik,
try this:

if a == 1 then error("1")
elseif a == 2 then return 3+g(1)
else return 4+h(2)
end
end
g = f

you will see this:

I think that debug.traceback() takes the function names from the
bytecode, that apparently stores how each function - or "method", or
"field" - is called... but I'm not totally sure.

# Global substitution
# -------------------
# The next example does a job somewhat similar to string.gsub. It
# receives a pattern and a replacement value, and substitutes the
# replacement value for all occurrences of the pattern in a given
# string:
#
# function gsub (s, patt, repl)
# patt = lpeg.P(patt)
# patt = lpeg.Cs((patt / repl + 1)^0)
# return lpeg.match(patt, s)
# end
#
# As in string.gsub, the replacement value can be a string, a function,
# or a table.

<edrx> as I understand it there's the PEG layer, where we have just
patterns that can succeed or fail, but we don't have a way to
specify and return captures
<edrx> on top of that the full thing with the captures is built - and
I imagine that there should be a way to "project" a
pattern-with-captures into the world of
patterns-that-just-succeed-or-fail
<edrx> supposing that this guess is right
<edrx> I think that there are also some basic functions to lift a
pattern-that-can-just-succeed-or-fail
<edrx> to a pattern-with-captures
<edrx> like: in case of success return the match as a string (a
substring of the subject), or return the starting point of the
match, or the end of the match
<edrx> and there are also ways to build bigger pattern-with-captures
from smaller patterns-that-just-succeed-or-fail and
patterns-with-captures
<edrx> hmmm, actually it seems that there's a natural embedding of the
world of patterns-that-just-succeed-or-fail into the world of
patterns-with-captures
<edrx> a pattern-that-just-succeed-or-fail returns the position of the
end of the match when it succeeds and nil when it fails
<edrx> hmmm again
<edrx> it seems that there is also the world of
patterns-that-might-be-resumed versus
patterns-that-on-success-have-no-backtracking-information

Hypothesis: patterns with captures are really a separate layer on top
of simple patterns; in order to make a pattern fail depending on
captured values I need to "move down" some values using, say, a global
variable "foo" and
pattwithcapturesthanchangesfoo *
lpeg.P(function (subj, pos) return foo and pos end)
No, that doesn't work - I have to use lpeg.P(function ... end) twice.
What is the exact moment in which a pattern is considered to have been
matched, and its captures are converted from "instructions for
captures" into "the values of the captures"?

Here's a bug that I found in lpeg-0.5... compare the two transcripts
below, the output "foo>" is wrong.

Does that happen on other people's machines too? I'm using Debian

The current version (now at github [1]) has a method to print
these bytecodes. ('pattern:pcode()', when compiled with LPEG_DEBUG
defined.) However, there is no explicit way to export or have
other access to the code. But it shouldn't be difficult for another
library to access that code inside the corresponding userdata.
(See the print function 'lp_printcode' for inspiration.)
Please keep in mind that the current instruction set is different from
the one used back there in that paper, but the general idea is the same.

<edrx> hi all - sorry if this is an obvious questions (pointers
welcome) but: suppose that I have my own function for reading a
line, "getline", say - how do I implement something like lua's
interactive mode - in lua - using it and the debug library? I
need to concatenate the lines that I've read and see if the
result either (1) is a complete command, (2) is an incomplete
command, (3) is "wrong" - how do I distinguish betwe
<edrx> en these three cases?
<lhf> btw, the HOPL paper is done. managed to mention you wrt
metamethods.
<rici> lhf: thanks
<rici> edrx: do it the way lua.c does
<rici> try to compile the line, and see what error you get, if any
<lhf> try loadstring. if it does not fail, run the chunk. if it fails,
check the message for eof.

# The body of my message was just:
Speaking of syntax for lambdas: in RiscLua a backslash is a synonym
for "function" and "=>" is a synonym for "return". See:
http://www.wra1th.plus.com/lua/book/rb04.html
The patch that implements that is just what's contained in the two
"#ifdef GCW_SUGAR" blocks in the file "c/llex" of RiscLua's sources
(<http://www.wra1th.plus.com/lua/zip/Luasrc.zip>); this "c/llex"
corresponds to the file "src/llex.c" in the standard Lua sources.

Adding another way to point to "levels" to debug.getinfo and friends
Hi list,
Two questions:
1) Is there a standard header that I can put in my e-mails that means
"this is _NOT GOING to be used in production code UNDER ANY
CIRCUMSTANCES_, this is going to be a personal hack that I will
only load into a Lua interpreter BY HAND for some VERY CONTROLLED
tests, etc, etc"?
(Can you please suppose that I started my e-mail with a header like
this? I've been considering asking the question below here at the
list for YEARS, but EVERY SINGLE TIME I predicted the probable
reaction of the professional programmers in the list and gave
up...)
By the way, I am the author of the article "Bootstrapping a Forth
in 40 lines of Lua code" that appeared in the Lua Gems book. One of
its last paragraphs is this:
I've met many people over the years who have been Forth
enthusiasts in the past, and we often end up discussing what made
Forth so thrilling to use at that time - and what we can do to
adapt its ideas to the computers of today. My personal impression
is that Forth's main points were not the ones that I listed at
the beginning of this section, and that I said that were easy to
quantify; rather, what was most important was that nothing was
hidden, there were no complex data structures around with
"don't-look-at-this" parts (think on garbage collection in Lua,
for example, and Lua's tables - beginners need to be convinced to
see these things abstractly, as the concrete details of the
implementation are hard), and _everything_ - code, data,
dictionaries, stacks - were just linear sequences of bytes, that
could be read and modified directly if we wished to. We had total
freedom, defining new words was quick, and experiments were quick
to make; that gave us a sense of power that was totally different
from, say, the one that a Python user feels today because he has
huge libraries at his fingertips.
The technical question that I want to ask is related to using Lua
as Forths were used in the early 90's - there were LOTS of commands
that if used wrongly could freeze the system and require a reboot,
and we were perfectly happy with that.
2) Here is the idea; the question is below.
The functions debug.getinfo, debug.getlocal and debug.setlocal are
usually called with an integer argument that the manual refers to
as "level", that is processed like this (I took the code from
db_getinfo, in ldblib.c) to set the variable "ar" to an "activation
record":
if (lua_isnumber(L, arg+1)) {
if (!lua_getstack(L1, (int)lua_tointeger(L, arg+1), &ar)) {
lua_pushnil(L); /* level out of range */
return 1;
}
}
I would like to have _variants_ of these functions, to be called
debug.mygetinfo, debug.mygetlocal and debug.mysetlocal, that would
accept an alternative to a numerical "level". Running
ar = debug.mygetstack(2)
would set ar to a string like
"activation record: 0x125cf20"
whose address part points to the "activation record" of a function
in the call stack, like the pointer that
lua_getstack(L1, (int)lua_tointeger(L, arg+1), &ar)
puts into ar, and if we are super-ultra-careful then we can call
debug.mygetinfo, debug.mygetlocal and debug.mysetlocal in either of
these ways, the second one being equivalent to the first one:
debug.mygetinfo (2, "n")
debug.mygetinfo (ar, "n")
debug.mygetlocal(2, 3)
debug.mygetlocal(ar, 3)
debug.mysetlocal(2, 3, 42)
debug.mysetlocal(ar, 3, 42)
But OF COURSE if we set ar to a bad address, say,
ar = "activation record: 0x12345678"
then debug.mygetinfo, debug.mygetlocal and debug.mysetlocal WOULD
NOT HESITATE to use that address and segfault (HAHAHA! DEAL WITH
THIS, MODERN PROGRAMMERS!!!)...
The question is: has anyone implemented something like this, or
something that would cover a part of this? I haven't written any C
code in ages... I think I can implement it myself, alone, but that
would take me one or two full days just for a prototype in which I
would just change ldblib.c... putting these new functions into a
".so" would take more.
Thanks in advance!!!

<edrx> hi (& happy new year =)) -
<edrx> I'm looking for hints on how to use luarocks more
verbosely...
<edrx> my current way of using it is through the sequences of
commands stored in these messy notes (which come with an
implicit "you are not expected to understand this" - summary
soon):
<edrx> http://angg.twu.net/e/lua5.e.html#luarocks
<edrx> so, for installing, for example, luarepl, I'd do this:
<edrx> ./luarocks download luarepl
<edrx> ./luarocks build luarepl 2>&1 | tee olb-luarepl
<edrx> which leaves a copy of the ___.rock and a build log in a
known place
<edrx> but I have the impression that there must a way to make the
"./luarocks build" run more verbose - in particular, to make
it show which dirs are being used, and what is the current
pwd before running a sequence of commands.
<edrx> if anyone has any hints I'd love to hear... luarocks still
feels quite opaque to me =\

Hi all,
I am trying to understand more about luarocks by running it from the
lua5.1 interpreter... I added this to my $LUA_INIT file,
loadluarocks = function ()
package.path = "/usr/share/lua/5.1//?.lua;/usr/share/lua/5.1//?/init.lua;"..package.path
command_line = require("luarocks.command_line")
program_name = "luarocks"
program_description = "LuaRocks main command-line interface"
commands = {}
commands.help = require("luarocks.help")
commands.pack = require("luarocks.pack")
commands.unpack = require("luarocks.unpack")
commands.build = require("luarocks.build")
commands.install = require("luarocks.install")
commands.search = require("luarocks.search")
commands.list = require("luarocks.list")
commands.remove = require("luarocks.remove")
commands.make = require("luarocks.make")
commands.download = require("luarocks.download")
commands.path = require("luarocks.path")
commands.show = require("luarocks.show")
commands.new_version = require("luarocks.new_version")
end
so that I can do things like this:
Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio
> loadluarocks()
> command_line.run_command("help")
and replace functions dynamically, adding print-like statements to
them.
One thing that I find very frustrating about luarocks is that I've
never managed to learn how to run it more verbosely... for example, if
I run this from from a shell,
sudo luarocks remove lpeg
sudo luarocks install lpeg
then the output shows how to build lpeg without luarocks - something
like:
Installing http://luarocks.org/repositories/rocks/lpeg-1.0.0-1.src.rock...
Using http://luarocks.org/repositories/rocks/lpeg-1.0.0-1.src.rock... switching to 'build' mode

Updating manifest for /usr/local/lib/luarocks/rocks
lpeg 1.0.0-1 is now built and installed in /usr/local/ (license: MIT/X11)
but I would like to make that output even more verbose, showing the
"chdir"s, the calls to tar and unzip, and the "cp"s - and, ideally,
but that may be much harder, to have a way to make luarocks run like
"make -n", showing the commands that it would run, but without running
them...
Any help or hints would be VERY appreciated. I understand very little
of the sources right now...
Cheers =),

Executable notes: LuaRocks
Hi all,
Lua has been my favorite language since 2000 but I use it in a very
unix-ish way - I use pipes and io.popen() to call external programs
instead of loading existing libraries written in C or writing my own -
and I use luarocks very little because I feel that don't understand it
(them?) well enough... which means that I use Lua practically without
batteries.
A few months ago I gave a talk at the EmacsConf2019 about how I keep
"executable notes" of everything that I do, and I finished it with a
demo. It's here, and there is even a transcript of the demo part:
http://angg.twu.net/emacsconf2019.html
I will use some of the tricks shown there in the demo part of the
video to explain why some things in LuaRocks are still mysterious to
me.
1. LuaRocks on Debian
=====================
I'm in a Debian box with lua5.1, lua5.2, lua5.3 and luarocks
installed, which means that I've done this:
sudo apt-get install lua5.1 lua5.2 lua5.2 luarocks
I use a huge LUA_INIT file, but if I run this in a shell
export LUA_INIT=
lua5.1
I get a "pure" Lua5.1.
If I do
luarocks
luarocks search lpeg
luarocks list
luarocks --verbose --local install lpeg 2>&1 | tee /tmp/olrl
luarocks --verbose --local install lpeglabel 2>&1 | tee /tmp/olrll
luarocks list
I install lpeg and lpeglabel in ~/.luarocks/, and luarocks also puts
some files in ~/.cache/luarocks/. These sexp hyperlinks
# (find-sh "cd ~/.luarocks/ && find * | sort")
# (find-fline "~/.luarocks/")
# (find-fline "~/.luarocks/share/lua/5.1/")
# (find-fline "~/.luarocks/share/lua/5.1/" "re.lua")
# (find-fline "~/.luarocks/share/lua/5.1/" "relabel.lua")
# (find-fline "~/.luarocks/lib/lua/5.1/")
# (find-fline "~/.luarocks/lib/lua/5.1/" "lpeg.so")
# (find-fline "~/.luarocks/lib/lua/5.1/" "lpeglabel.so")
# (find-sh "cd ~/.cache/luarocks/ && find * | sort")
# (find-fline "~/.cache/luarocks/")
# (find-fline "~/.cache/luarocks/https___luarocks.org/manifest-5.1")
help me inspect these directories and remember where the files are.
If I execute this in a shell
export LUA_INIT=
lua5.1
require "lpeglabel"
require "relabel"
I get errors, because neither "relabel.lua" nor "lpeglabel.so" are
found. If I run this in a shell,
luarocks path
luarocks path | tr "';" "\n\n"
I see that there are two ways to make Lua use these paths. One is:
export LUA_INIT=
eval $(luarocks path)
echo $LUA_PATH
echo $LUA_CPATH
lua5.1
require "lpeglabel"
require "relabel"
and another is
export LUA_INIT=
lua5.1
home = os.getenv "HOME"
package.path = home.."/.luarocks/share/lua/5.1/?.lua;" .. package.path
package.path = home.."/.luarocks/share/lua/5.1/?/init.lua;" .. package.path
package.cpath = home.."/.luarocks/lib/lua/5.1/?.so;" .. package.cpath
require "lpeglabel"
require "relabel"
so far so good - but I confess that I didn't find easy to figure this
out when I started using rocks several years ago.
2. Understanding a rock
=======================
How do I get the documentation of a rock? Does that documentation
always come with examples? Does the source always come with
documentation and examples? How do I download and unpack the source of
a rock?
I found - by trial and error - that I can do this,
luarocks
luarocks list
luarocks show lpeglabel
rm -Rv /tmp/lpeglabel/
mkdir /tmp/lpeglabel/
cd /tmp/lpeglabel/
luarocks download lpeglabel
unzip lpeglabel-1.6.0-1.src.rock
tar -xvzf v1.6.0-1.tar.gz
# (find-fline "/tmp/lpeglabel/")
# (find-fline "/tmp/lpeglabel/lpeglabel-1.6.0-1/")
# (find-fline "/tmp/lpeglabel/lpeglabel-1.6.0-1/README.md")
# (find-fline "/tmp/lpeglabel/lpeglabel-1.6.0-1/relabel.lua")
# (find-fline "/tmp/lpeglabel/lpeglabel-1.6.0-1/examples/")
but I don't have any idea if all rocks can be extracted in a similar
way... my video for the EmacsConf has a part that shows how I have
semi-automated the task of downloading the source of a Debian package
and unpacking and compiling it:
http://angg.twu.net/emacsconf2019.html ->
14:45 Demo: the `find-apt-get-source-links' ->
https://www.youtube.com/watch?v=86yiRG8YJD0&t=885
Can something similar be done for rocks? I don't know - I've tried to
do something like this a few years ago, and 1) I ended up with the
impression that there are several different ways to pack and unpack
rocks, 2) I tried to follow what luarocks do - but telling it to run
in verbose mode didn't make it verbose enough, 3) I tried to add some
prints and calls to repls to luarocks's code and to call its functions
from Lua's default REPL but I didn't get very far, 4) I sent the
following e-mail to the luarocks mailing list,
https://sourceforge.net/p/luarocks/mailman/message/34636407/
but soon after that I gave up...
Cheers,
Eduardo Ochs

Problem with luarocks unpack
Hi list,
ok, so Lua is a geek language with geek batteries, right? This means
that it should be easy to download and unpack the full source of any
given rock, right?...
I'm on Debian, and the version of the luarocks that comes with Debian
is 2.4.2 - see:
https://packages.debian.org/sid/luarocks
There are some rocks that that version can't install. Just to cite an
obvious example, I tried to ask the luarocks from Debian to install
the most recent version of luarocks - some package managers are able
to do this - by doing:
luarocks --local install luarocks
and I got these error messages:
Installing https://luarocks.org/luarocks-3.2.1-1.src.rock
Error: Rockspec format 3.0 is not supported, please upgrade LuaRocks.
So I tried to install a recent version of luarocks from the git repo.
Here's what I did:
sudo apt-get remove luarocks
# Clean all the stuff from previous uses of luarocks
rm -Rfv ~/.cache/luarocks/
rm -Rfv ~/.luarocks/
cd ~/usrc/
git clone https://github.com/luarocks/luarocks
cd ~/usrc/luarocks/
# Choose a version
git branch --list -a
git checkout 3.2.1
git reset
./configure
make
sudo make install
which luarocks
luarocks --version
rm -Rv /tmp/rock/
mkdir /tmp/rock/
cd /tmp/rock/
luarocks unpack stacktraceplus
# Output:
# "Error: Failed copying unpacked rockspec into unpacked source directory."
I got the same error on several rocks. What I am doing wrong?
"luarocks unpack" is not well documented, so I am mostly guessing that
it is the right thing for downloading rock sources...
Thanks in advance,
Eduardo Ochs

Subj: Status of lexpect?
Hi Steve,
what is the status of lexpect? Is the version from
http://mysite.mweb.co.za/residents/sdonovan/lua/lua-gdb.zip
the latest one? I'm trying to run it - recompiling the ".so"s in a
naive way - and I'm getting a linking error...
Here's what I've done:
rm -Rv ~/usrc/lua-gdb/
unzip -d ~/usrc/ $S/http/mysite.mweb.co.za/residents/sdonovan/lua/lua-gdb.zip
cd ~/usrc/lua-gdb/
rm -Rv *.dll
rm -Rv *.so
gcc -shared -I$LUA51SRC/src spawnx.c -o spawnx.so
gcc -shared -I$LUA51SRC/src stubby.c -o stubby.so
and then doing a "require 'lexpect'" in Lua fails, and if I try to
debug the problem here's what I get:
/home/edrx/usrc/lua-gdb(edrx:pe)# $LUA51SRC/bin/lua
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
> require "path"
> if not path.loadlib('lexpect','spawnx') then
>> print 'cannot find spawnx in same directory as lexpect.lua'
>> end
cannot find spawnx in same directory as lexpect.lua
> = path.loadlib('lexpect','spawnx')
nil cannot load extension: ./spawnx.so: undefined symbol: forkpty
>
Any hints? What is the right way to build the ".so"s? 8-\
Cheers & thanks in advance,

P.S.: I'm running all this in a Debian Stable ("Lenny") box...

(His answer:)
(...)
The only thing missing is -lutil for spawnx.c so that forkpty() can be found.
x in same directory as lexpect.lua
> > = path.loadlib('lexpect','spawnx')
> nil cannot load extension: ./spawnx.so: undefined symbol: forkpty
> >
It would help if the code actually gave the proper error message ;)
I'll package it properly, sorry packaging quality ain't always my
strong point. I'm intending to make lexpect/luagdb available as rocks,
but I'll sort out the makefiles as well.

Ei, acabei de ter uma ideia muito legal relacionada a essa historia de
passar os scripts todos pra Lua...
Quando o shell recebe uma linha como
wget -q -O - http://foo/bar | apt-key add -
ele separa ela em "comandos" (o "|" e' um sinal de diz como conectar
dois comandos separados) e depois em "palavras"; cada comando vira um
processo, e estes processos estao ligados entre si de certos modos...
por exemplo, o output do "wget" e' um pipe que e' o input do
"apt-key", e se o shell receber certos "signals" do wget ou do apt-key
ele retransmiste esses signals pro outro programa da pipeline...
Bom, shells interpretam essas pipelines criando processos conectados -
e fazem isso com umas rotinas em C que nao sao compridas (umas 100
linhas, acho, em codigo de baixo nivel que chama diretamente as kernel
calls) e que eu sempre quis entender...
Acho ate' que a parte em C necessaria pra gente fazer tudo isso a
partir de Lua ja' deve estar toda pronta dentro do lposix... e, bom,
tendo as ideias e as desculpas certas da' pra mandar umas mensagens
pra lista de Lua e os bichos de C e POSIX da lista vao produzir num
instante o codigo em lua que executa coisas como:
w = command({"wget", "-q", "-O", "-", "http://foo/bar"})
a = command({"apt-key", "add", "-"})
p = pipeline({w, "|", a})
run(p)
E ai' vamos ter uma biblioteca para fazer shells em Lua, que e' algo
que vai interessar a muita gente...
Ah, a parte de editar os arquivos de configuracao do Plurall usando
Lua e' facilima, claro...
[]oooooo,
Edrx

Hello. I am a developer from Phyzios, Inc. We've created a web application
using Lua Alchemy (http://code.google.com/p/lua-alchemy) and Box2d Flash
World Construction Kit (http://github.com/jesses/wck). By using the
application, you can create your own physics world by writing Lua codes.
Phyzios Lab: http://phyzios.net/Lab/
This is a research project and currently is a closed beta version. We
appreciate any comment/feedback/suggestion from you. Thanks.

Just a vague idea at the moment... Here it is. It shouldn't be hard to
code in Bison and Lexx the syntax of Lua; the result of parsing a lua
chunk should be a Lua chunk that creates a tree-ish data structure in
Lua -- something like what I do in "newtrees.lua" --, and these tress
will then be easy to process.

# Closure reductions (e-mail sent to Marc Simpson)
# 2010dec29
#
#####
# «closure-reductions» (to ".closure-reductions")
# (find-TH "__mt")
Hi Marc!
This is my favourite example for explaining closures:
foo = function () -- foo returns two functions...
local storage
return
function () return storage end, -- a "getter",
function (x) storage = x; return x end -- and a "setter".
end
get1, set1 = foo() -- get1 and set1 use a first "storage"
get2, set2 = foo() -- get2 and set2 use a second, different "storage"
print(set1(22), get1()) --> 22 22
print(set2(33), get1(), get2()) --> 33 22 33
Rewriting it with \, =>, and shorter var names, it becomes:
foo = \ () local st
=> \ () => st end,
\ (x) st = x; => x end
end
g1, s1 = foo()
g2, s2 = foo()
print(s1(22), g1())
print(s2(33), g1(), g2()
Only yesterday I realized that we can distinguish different local
variables with same name but with different scopes - and that includes
the ones used in closures, of course - by writing their time of
creation as a subscript... so:
foo = \() local st; => \() => st end, \(x) st = x; => x end end
g1, s1 = foo()
--~-> (\() local st; => \() => st end, \(x) st = x; => x end end)()
--~-> (\() local st_1; => \() => st_1 end, \(x) st_1 = x; => x end end)()
--~-> \() => st_1 end, \(x) st_1 = x; => x end
g2, s2 = foo()
--~-> (\() local st; => \() => st end, \(x) st = x; => x end end)()
--~-> (\() local st_2; => \() => st_2 end, \(x) st_2 = x; => x end end)()
--~-> \() => st_2 end, \(x) st_2 = x; => x end
-- Now we have:
-- g1 = \() => st_1 end

Maybe this trick would be enough to display your classes and instances
- and the ones in chapter 16 of PiL - as static objects, maybe not...
Probably your trick to backup "this" and "priv" deserves another
shortand...
More soon!

Hi Tom,
> The ZeroBrane site has no link to download the Linux version.
You can get the latest version from the repository and run "bash
./zbstudio.sh" (or use CMake build file in the build/ directory).
Running zbstudio.sh the first time will install the dependencies and
then run the IDE (tested on Ubuntu and Mint versions of Linux, but
should work anywhere with deb packaging support). I'll have a packaged
shell archive when the next version (0.33) is out.
I've described how this is done in my debugger (MobDebug:
https://github.com/pkulchenko/MobDebug) in this SO answer:
http://stackoverflow.com/a/11026978/1442917. It also integrates with
an IDE (in the signature), so you can see how this type of debugging
can work.

# eoo.lua: OO in 5 lines of code
Hello list,
I have just finished rewriting the documentation of eoo.lua, that is a
very minimalistic implementation of OO in Lua in just 5 lines of code.
Its code is just this, except for some functions that I only use very
rarely:
Class = {
type = "Class",
__call = function (class, o) return setmetatable(o, class) end,
}
setmetatable(Class, Class)
Most people will probably think that this has too few features to be
useful to them, but the diagrams in the documentation are very nice,
and can be adapted to other implementations of OO too (I guess).
It is here:
http://angg.twu.net/LUA/eoo.lua.html
http://angg.twu.net/LUA/eoo.lua
Cheers,

OO in five lines of Lua
Hi list,
I just added lots of documentation, including box diagrams and a
detailed example of use, to the OO mechanism that I've been using for
years, whose main part is just these these five lines of Lua code:
Class = {
type = "Class",
__call = function (class, o) return setmetatable(o, class) end,
}
setmetatable(Class, Class)
The code and the comments are here:
http://angg.twu.net/LATEX/dednat6/eoo.lua.html (htmlized)
http://angg.twu.net/LATEX/dednat6/eoo.lua (original)
I guess that most people here will find it almost offensibly simple
but I have hope that some people will find the box diagrams and the
reduction diagrams in its documentation inspiring... maybe even to the
point of creating box diagrams for some of the OOs here:
http://lua-users.org/wiki/ObjectOrientedProgramming
http://lua-users.org/wiki/ObjectOrientationTutorial

Cheers =),

Why there isn't a package called "lua5.3-doc" in Debian?
Hi list,
I just noticed that there isn't a "lua5.3-doc" package for Debian, and
that none of the packages generated from the lua5.3 Debian source
package contains a file "manual.html"... where can I find the
rationale for that? I grepped the Debian sources and found nothing...
Thanks in advance!

# lua-shepi - Tiny EDSL for shell pipes in lua
# 2020jan17
#
#####
# «lua-shepi» (to ".lua-shepi")
# «lua-shell-pipes» (to ".lua-shell-pipes")
# https://luarocks.org/modules/forflo/lua-shepi
# https://github.com/forflo?tab=repositories
# https://github.com/forflo/shepi
The EDSL uses the same left-to-right evaluation order and the pipe
character | that you are familiar with. For instance local pipe =
bp.echo('foo bar') | bp.tr('-d', ' ') becomes possible (see the
examples further below).
- There are no tempfiles.
- Space complexity for normal shepi pipes is constant (not taking into
account the commands in the pipeline of course).
- If you are using the shepi.fork function, space complexity is O(n) =
n, because it synchronuously joins the subpipes in order. (n referes
to the data input from the subpipes.)
- You can throw lua functions into the pipe. They also do run in a
separate process!
- You can reuse your pipes, since they are just regular lua-functions.
- And, of course, there won't be zombie processes (but that's not
really a hightlight).

Problem with -0
Hi list,
a few hours ago I noticed for the first time that print(0*-2) prints
"-0" instead of "0" - because Lua supports
<https://en.wikipedia.org/wiki/Signed_zero> - and I tried to write a
function that would "fix" the "-0"s in the cases that I don't want
them... and well, it turns out that this doesn't work on Lua 5.1.5:
fix0 = function (x) if (x == -0) then return 0 else return x end end
Here's a test:
--snip--snip--
cd
cat > /tmp/testminus0.lua <<'%%%'
f = function (x) if (x == 0) then return 0 else return x end end
g = function (x) if (x == -0) then return 0 else return x end end -- buggy on Lua5.1
h = function (x) if (x == -0) then return 42 else return x end end
print(f(0), f(-0), f(99))
print(g(0), g(-0), g(99))
print(h(0), h(-0), h(99))
%%%
lua5.1 /tmp/testminus0.lua
lua5.2 /tmp/testminus0.lua
lua5.3 /tmp/testminus0.lua
lua5.4 /tmp/testminus0.lua
--snip--snip--
It prints this:
/home/edrx(edrx:sc)# lua5.1 /tmp/testminus0.lua
0 0 99
-0 -0 99
42 42 99
/home/edrx(edrx:sc)# lua5.2 /tmp/testminus0.lua
0 0 99
0 0 99
42 42 99
/home/edrx(edrx:sc)# lua5.3 /tmp/testminus0.lua
0 0 99
0 0 99
42 42 99
/home/edrx(edrx:sc)# lua5.4 /tmp/testminus0.lua
0 0 99
0 0 99
42 42 99
/home/edrx(edrx:sc)#
So it seems that this doesn't work,
fix0 = function (x) if (x == -0) then return 0 else return x end end
but this does:
fix0 = function (x) if (x == 0) then return 0 else return x end end
Where is that bug documented? I would like to put in my code a link
that explains why the "more natural" version with (x == -0) doesn't
work, and why we need the "weird" version with (x == 0)...
Thanks in advance!

What you can do is simply use pcall, and check that the error message
is "interrupted!".

It's in the same vain as tryruby.org and the like. It will remember the
state of your session until the next browser reload.

A good example to look at is LuaSocket [1], where 'socket' is a Lua
module that builds on the undocumented "internal" C module,
'socket.core'.

Even if you didn't have sleep. You can just use select with empty sets :)
require "socket".select(nil,nil,0.5)
Or using SIP:
> res = {}
> = sip.match('Local Socket: $S{addr}..$i{port}',p,res)
true
> = res.port
750
