SID-00428: itex2mml or itextomml (Windows XP)

I'm trying to install the [[http://twiki.org/cgi-bin/view/Plugins/LaTeXToMathMLPlugin ][LaTexToMathMLPlugin]] but as a prerequisite I need to install [[http://pear.math.pitt.edu/mathzilla/itex2mml.html ][itex2mml]. Unfortunately I'm not able to find a windows binary for this file. There use to be one here:

http://golem.ph.utexas.edu/~distler/blog/archives/000319.html

but the link seems no longer valid:

Discussion and Answer

I forgot to add, well I wait for a response, I am currently downloading a C compiler. This however scares me. Assuming I can compile it correctly, I'm not sure I"ll know how to configure it. For instance will I need to create any bat files or make any registry changes.

-- JohnCreighton - 2009-07-21

So anyway, I downloaded borland turbo C++. I'll still try to track down the binary but in the mean time I might try and learn a little about C.

Anyway, in the zip file supplied here: http://pear.math.pitt.edu/mathzilla/itex2mml.html

There is the following in the Make file:

http://www.opensource.apple.com/source/gnuzip/gnuzip-25/gzip/msdos/Makefile.bor

CC = gcc

itex2MML: y.tab.o lex.yy.o $(CC) -o itex2MML y.tab.o lex.yy.o

lex.yy.o: lex.yy.c y.tab.h

y.tab.c y.tab.h: itex2MML.y $(YACC) -d -v itex2MML.y

lex.yy.c: itex2MML.l $(LEX) itex2MML.l

Two issues I have. One, I'm wonder if the IDE is appropriate. Make files seem to be shell scripts and in the case of windows this would be a bat file. So maybe I should call the compiler from the command line (Sounds tricky). I don't know if I can get the compiler to use a make file from within the IDE. Also the shell commands from the last two dependencies seem to be lexical analyzers.

Here are some relevant links:

http://web.mit.edu/gnu/doc/html/flex_3.html http://www.debian.org/doc/manuals/debian-reference/ch12.en.html http://en.wikipedia.org/wiki/Lex_programming_tool

-- JohnCreighton - 2009-07-22

After some further thought since the output of lex is a generated c file, I don't think I need either flex or lex. But if I was to use them there seems to be some C sharp versions as mentioned by Wikipedia:

http://en.wikipedia.org/wiki/List_of_C_Sharp_lexer_generators

Or I could use the unix versions I suppose in windows by using Cygwin.

That said it is nice to know about these utilities. They sound quite powerful!

Okay, moving on. I don't quite know enough to compile it yet.

So I know, that lex.yy.o: is a lunix executable for a lexical analyzer which is compiled from the c file.

lex.yy.c with the header file: y.tab.h

The c file lex.yy.c is generated by using the lexical analizer generater "lex".

I know that y.tab.o is a lunix executable for a parser which is compiled from the c file:

y.tab.c with the header file: y.tab.h:

The c source y.tab.c is generated using the parser generator:

Yacc

http://en.wikipedia.org/wiki/Yacc

Now here is where I start to get uncertain.

In the make file the first shell command used to compile itex2MML is:

$(CC) -o itex2MML y.tab.o lex.yy.o

where $(CC)=gcc

http://cs.acadiau.ca/~jdiamond/comp2103/beginner-tutorials/LinuxTutorialGcc.html

The first argument to the compiler gcc, seems to be a lunix script file (lunix people please help) which uses the lunix shell http://linux.about.com/library/cmd/blcmdl1_sh.htm

Here what is in the file:

# /bin/sh

itex2tth <$1 >$1.tex

/home/paul/tth_linux/tth -r <$1.tex >$1.html

I presume $1 is the first input, so the script file takes, one input, there are two inputs passed to the compiler. I'm not sure how the compiler uses these inputs.

I believe that tth is a text to math math mark up language translator:

http://hutchinson.belmont.ma.us/tth/mml/

So does the compiler just generate a program, that links, a text to mathML translator, to a lexical analyzer and a parser? If so why? WHy not just use the tex to mathML translator directly. Also in the zip file there is a program called tidy, which can translate, a latex document into a math MML web page. Why not use this program directly. What am I missing?

-- JohnCreighton - 2009-07-22

Hmmmmmm.........Tidy seems to be a program to correct errors in HTML files:

http://en.wikipedia.org/wiki/HTML_Tidy http://tidy.sourceforge.net/

I'm not sure if it is used in itex2mml. I do neet to read more about "tth" though.

-- JohnCreighton - 2009-07-22

Forgot to add the link: http://hutchinson.belmont.ma.us/tth/

-- JohnCreighton - 2009-07-22

Okay, here is what I think. Tex is a lower level language then Latex.

http://en.wikipedia.org/wiki/LaTeX

and itex:

http://golem.ph.utexas.edu/~distler/blog/itex2MMLcommands.html

I think that the parsers in itex2mml translate itex into tex and then use the program "tth" to translate the tex into mathML.

What I don't understand is how the gcc compiler combines the tth with a parser and a lexical analyzer into a single program.
