Subject: passing buffer to lua functions
Date: Mon, 29 Sep 2008 21:53:51 +0200 [thread overview]
Message-ID: <20080929195351.GB14467@blackowl.org> (raw)
Dear all,
I'm trying to implement a very simple filter mechanism in lua like this:
\def\test#1{%
\startlua
local pipe, str
pipe = io.popen("./my_filter '\luaescapestring{#1}'", "r")
str = pipe:read("*a")
tex.print(str)
pipe:close()
\stoplua
}
\test{%
line 1
line 2
}
The issue I have is that the argument of test has its line breaks
removed in the process (i.e. the filter my_filter sees a single line
argument). How to prevent this while keeping the lua escape at the same
time? (I know I can implement such a thing with executecommand and using
buffers written to files, but I would like to avoid writing on the hard disk.)
Olivier
