[trying to get a red leftmargin]
Make a complete (with text) example where we can see your problem (a
example of the output could help), I get a red background for the
left margin.
Here it is. And the output (processed with texexec --lua) is attached.
Thanks for everything.

[NTG-context] Possible memory leak?
Hi, Hans:
in font-afm.lua, you use fontforge to open and to_table a pfb, but
without closing it?
btw, when MKIV is running for the first time (i.e., no cache file). it
will use a lot of memory (parsing a 10M font will use 700-800 MB
memory), are there some ways to reduce that? Another problem is, the
memory usage seems incremental:
I watch the memory usage in top carefully, it does not reduce when
MKIV finish reading and caching an otf font. (well I read the
font-otf.lua, and you are actually closing that font. so maybe that's
because luatex is leaking memory?)
btw, I load arial 300 times using the following file,
%engine=luatex
\directlua0{
function load_font (filename)
local metrics = nil
local font = fontforge.open(filename)
if font then
metrics = fontforge.to_table(font)
fontforge.close(font)
end
return metrics
end
myfont = load_font('arial.ttf')
% 300 myfont = load_font('arial.ttf')
myfont = load_font('arial.ttf')
myfont = load_font('arial.ttf')
myfont = load_font('arial.ttf')
myfont = load_font('arial.ttf')
}
and I can see the memory usage may ebb and flow, but actually it is
leaking memory.

Hi Yue Wang,

and I can see the memory usage may ebb and flow, but actually it is
leaking memory.
I also see a non-trivila leak (somewhere inside the fontforge library).
I will investigate further next week, it is not that massive. I get this
result for your input file, with 500 arial.ttfs (ArialMT version 3.0,
367112 bytes):
==8819== LEAK SUMMARY:
==8819==definitely lost: 16,965,191 bytes in 707,541 blocks.
==8819== possibly lost: 1,128 bytes in 22 blocks.
==8819==still reachable: 202,135,427 bytes in 81,127 blocks.
==8819== suppressed: 0 bytes in 0 blocks.
==8819== Rerun with --leak-check=full to see details of leaked memory.
So some 32kb per font. Noticeable, but not enormous. The growth in
'top' is probably caused more by memory fragmentation than by this leak.
Best wishes,
Taco

Hello, Kevin D. Robbins krobb...@alumni.princeton.edu writes: Thanks for the suggestions Wolfgang and Luigi. I've now got several good options to research. Kevin I use 3 modes for teaching: manuscript -- notes that go on-line for students to download presentation -- pictures for use in class speakernotes -- miniatures of the pictures, each on a separate page, that I scrawl on for use in class (so I know what I'm supposed to say). I got a lot of help from this list in putting these together. Context experts might find them laughable, but I'm attaching the modes in a tarball just in case they are useful.

Re: [NTG-context] Possible memory leak?
ok, thanks for noticing, i added a
fontforge.close(pfbblob)
good
btw, when MKIV is running for the first time (i.e., no cache file). it
will use a lot of memory (parsing a 10M font will use 700-800 MB
hm so much?
Yes, when finish reading the following tex file without \bye using plain TeX,
LuaTeX will cost 719M memory on my machine. The font used is Adobe
song std light.
[...@localhost ~]$ cat a.tex
\directlua0{
function load_font (filename)
local metrics = nil
local font = fontforge.open(filename)
if font then
metrics = fontforge.to_table(font)
fontforge.close(font)
end
return metrics
end
myfont = load_font('song.otf')
}
[...@localhost ~]$
when using the above script loading four fonts (you can try this by
adding 3 myfont = load_font('song.otf')),
the memory consumption will be higher than 1G on my machine. Remember
I am using Plain TeX to do this test, MKIV will consume more memory.
also, mem consumption reported is a bit of a lie because lua seems to
allocates double of what it needed with each increment but not always use it
otf fonts are already quite packed in mkiv (i'm considering adding an option
to mtx-font to precache fonts but i'm not sure if it's worth the trouble
is mem consumption less a second run?
Yes, dramatically less. with 4 chinese fonts loaded (I use zhfonts.tex
for testing), MKIV consumes 300-400MB.
