Hello all,
while working on my ebook, I found the following issues in mtx-epub.lua. Once a successful run is done, there is no need to try the other zippers. It also gives error messages, although everything is already done. Fix is attached.
Then, I got confused about the error messages appearing 3 times and found an issue in texlua of TL2011 (beta-0.70.1-2011062107) as well as the newest standalone (beta-0.70.2-2012052309). Consider the following example:
print(os.execute("abcxyz"))
This gives in Lua 5.2: sh: abcxyz: command not found
nil exit 127
But in texlua it does: sh: abcxyz: command not found
32512
This breaks the if conditional which becomes true, although there is no abcxyz command. If there are if statements such as this one in other places, they would not work as intended either.

As we give a list of zippers on failure, the following might be better:
local done = false
for i=1,#zippers do
local zipper = zippers[i]
if
os.execute(format(zipper.uncompressed,epubfile,"mimetype")) then
os.execute(format(zipper.compressed,epubfile,"META-INF"))
os.execute(format(zipper.compressed,epubfile,"OPS"))
done = zipper.name
break
end
end
lfs.chdir("..")
if done then
application.report("epub archive made using %s:
%s",done,file.join(epubpath,epubfile))
else
local list = { }
for i=1,#zippers do
list[#list+1] = zipper.name
end
application.report("no epub archive made, install one of:
%s",concat(list," "))
end
(I will look into the os.execute later .. remind me if needed.)
