To be pedantic: this code is largely in TeX, not LaTeX.

stettberger4• 12 years ago

This is true, but largly in TeX and only Parts of it in LaTeX is still LaTeX. But you're right, I did use only a few rudimentary features.

SeanLuke2• 12 years ago

I think this is the minority view of LaTeX: it's built on top of and is a subset of TeX, not a superset. No one would ever consider \def to be LaTeX for example.

Not to denigrate what you produced of course.

Nice work, though I liked the dataref package even more!

stettberger4• 12 years ago

The dataref package is intended to be useful (and it acutally is). Avremu was only a long trip in sweden without internet, an editor and a reference manual.

"Are you insane? Not that anybody knows of."

hahaha that cracked me up, especially that i actually considered the possibility when i read the title.

This is mental and I love it.

That reminds me of this, a slightly bigger AVR emulating an ARM SoC running Linux:

Emulate that system instead, and now you can theoretically boot a Linux system inside of TeX.

stettberger4• 12 years ago

I already considered that, but until now i did not implement many peripheral devices. But when implemented those, it should be possible. But at the moment i'm rather thinking of an VHDL netlist emulator in TeX.

why?

stettberger4• 12 years ago

Sweden, Too much time, Masterthesis was submitted.

In the 1990s, when I was in college, I wrote a 6502 emulator in a text editor macro language (the text editor was QEdit, a DOS editor that was popular at the time). It was completely useless but a lot of fun.

There was a very low hard limit on the number of jumps (32, if I recall correctly) that complicated things. I eventually had to resort to a two step process, first translating 6502 code to a simpler virtual machine (using and abusing the find-and-replace command), and then executing that simpler code.

this is cool and you seem obviously intelligent, have you considered making something people want?

marvy• 12 years ago

sometimes, cool is enough :) I might actually want this though. C is much more convenient than TeX to code in, and yet sometimes you have no choice. Until now.

I wonder if this could be modified to control actual hardware? It looks the `\write18` command can be used to execute shell commands if LaTeX is run with the `--shell-escape` option. So in theory you could intercept all writes to the GPIO control registers and use a shell command to send bytes over the serial port to a physical MCU (or something like the SparkFun SPI Shortcut.)

Imagine a LaTeX document that, when processed, reads a series of measurements from a sensor over the serial port, then renders nice graphs directly to a PDF! :)

I was looking for this workflow for my research, and ended up going with an ipython notebook.

We need more of this.
