Set TM_LATEX_FLAGS=--shell-escape.

You can do this in the Shell Variables preference pane of TextMate's preferences, or on a per-project basis.

This is some old cruft that will be removed. Basically, I wanted to treat “preamble files” specially, but I needed a way to recognize them. Now, you can just use the extension “ltx” to indicate that you are working on a preamble file.

By “preamble file” I mean the tex source of a “fmt file”.  A fmt file is essentially a memory dump from the tex processor.  You can do something like this:

Create a file my-format.ltx with contents:

> \documentclass{article}
> \usepackage{myfavoritepackage}

When you build this file with ⌘R, LaTeX2 will produce a “my-format.fmt” file. What do you do with a fmt file?

Create my-document.tex with these contents:

> %&my-format
> \begin{document}
> HI
> \end{document}

This will build just fine! The fmt file is just a binary dump of tex's memory contents after loading the article class and myfavoritepackage. fmt files can really speed up compiling for documents that do a lot of usepackaging and command-defining in the preamble.
