Hello,
I'd need to call the OS, namely lua in it.
I have the following code:
----
\write18{lua -e "require 'lfs'"}
\write18{lua -e require'lfs'}
\starttext
A
\stoptext
----
When calling directly from the command line
lua -e "require 'lfs'"
- there is no error.
From within the Context code, I'm getting (see CmdLine.log):
"
...
lua.exe: (command line):1: '=' expected near 'lfs'
lua.exe: (command line):1: '=' expected near '<eof>'...
"
What could be the problem?
My OS is WinXP 32b.
Best regards,
Lukas

And how about
\ctxlua{os.execute(lua -e "require 'lfs'")}
btw, if you run texlua you get lfs for free.

OK, this is just a sample. I need to use another file, in fact.

Hello,
I slightly modified the example - my code now is:
----
\ctxlua{os.execute([[echo lua -e "print 'WWW'"]])}
\starttext
A
\stoptext
----
So now I'm able to diagnose what exactly is passed to the command line.
I'm getting:
"
...
languages > language en is active
lua -e "print "WWW""
{c:/ConTeXt/tex/texmf-context/fonts/map/pdftex/context/mkiv-base.map}
...
"
So it can be seen that [surprisingly] character ' was substituted for " - and IMHO this causes the problem.
Could anyone explain why this substitution is performed and how to avoid it?
Best regards,
Lukas

probably some os.execute parsing ... does os.exec or os.spawn work ok?

Do you mean Lua itself does the parsing and substitution? I guessed [lua]tex core...
When I try to call on the command line:
"
C:\Lukas\ConTeXt\TestDDv>lua
Lua 5.1.4 Copyright (C) 1994-2008 Lua.org, PUC-Rio
> os.execute([[lua -e "print 'WWW'"]])
WWW
> os.execute([[echo lua -e "print 'WWW'"]])
lua -e "print 'WWW'"
> =os.exec
nil
> =os.spawn
nil
>
"
- There is no '/" substitution in standalone Lua (?!).
> does os.exec or os.spawn work ok?
Well, the 'os.exec' works, in condition that it is called with "cmd /c":
----
\ctxlua{os.execute([[echo lua -e "print 'EXECUTE'"]])}
\ctxlua{os.exec([[cmd.exe /c echo lua -e "print 'EXEC'"]])}
\ctxlua{os.spawn([[cmd.exe /c echo lua -e "print 'SPAWN'"]])}
\starttext
A
\stoptext
----
Gives:
"
...
languages > language en is active
lua -e "print "EXECUTE""
lua -e "print 'EXEC'"
system | total runtime: 0.609
"
Interesting that the string to be passed to 'os.exec' keeps ' whilst that to 'os.execute' doesn't.
Why this happens?
Anyhow, thanks for the idea with 'os.exec'.
Best regards,
Lukas

you can try texlua instead of lua to see what happens

... Finally, I use the following to avoid ' in arguments and to keep " to os.execute():
----
\bgroup
\catcode`\%=11
\ctxlua{os.execute(([[echo lua -e "print 'EXECUTE'"]]):gsub("'(.-)'", "[[%1]]"))}
\egroup
% Or:
\startluacode
os.execute(([[echo lua -e "print 'EXECUTE'"]]):gsub("'(.-)'", "[[%1]]"))
\stopluacode
\starttext
A
\stoptext
----
None of both solutions are "pure" as I'd imagine but they seem to work.
Best regards,
Lukas
