Hi,
I would like to use in my documents double braces for the footnote –
for easily matching entire footnotes with RegEx (thus it can't
confuse with the nested braces) ...
text\footnote{{this is {\it one} tiny note\index{note}!}}
... and match the entire footnote with search regex for \\footnote\{\
{.+\}\}
Is this save? Or are there unwanted side-effects when using \footnote
{{ ... }} ?
Steffen

Nested patterns is something where gema really excels. Here is a gema script to convert \footnote{{something}} to \footnote{something} :\\footnote\W\{\{<matchbrace>\}\}=\\footnote\{$1\} matchbrace:\{#\}=\{#\} matchbrace:\\<Y1>=\\$1 Save it as footnote.gema and then run gema -f footnote.gema tex-file > output-file It handles these expressions correctly: \footnote{{This $\frac{a}{b^{c+d}}$ is a strange footnote}} \footnote{{This $\frac{a}{b^{c+d}}$ is a strange footnote with multiple {nested {expressions}}}} \footnote{{This $\frac{\left[\frac {a}{b}\right\}}{c}$ is a strange footnote}} It is much easier to write than regular expressions. Unfortunately, gema expressions can be as hard as regular expressions to read.

In vim you can highlight comands and their "regions" using region start, region end, and region contains. That can be used to highlight footnotes. (I once used something similar for highlighting sections in LaTeX, but no longer have that code). Of course, vim comes with rest of its baggage.

It recognizes keywords, string constants and comments, each can have a different (user definable) color. The comment start (usually --) and optionally comment end can be chosen via a preference panel.

Hi Steffen, Smultron does this on MacOS X: http://smultron.sourceforge.net/ In fact one can define easily a set of syntax colouring for almost anything with Smultron.

I don't know how many things I've read on the web to understand if regexps can handle nested delimiters or not (I think the long and short of it was that on some mathematical principle it just isn't possible); there is some pretty obscure perl stuff that might be able to do it but is highly experimental. If gema really can do this, it should be a godsend for processing TeX files. I have it installed now on my OS X box (but couldn't build the gel binary) and am looking forward to experimenting with it. All best, and thanks!

You have to redefine each and every command and make all special chars like $ and _ \active, but it is in fact pretty easy and fairly reliable. I would not do it like that again, these days I would use lpeg, but it was not nearly as complicated to do it in tex macros as I had anticipated.

If you set \tracingassigns=1 \tracingrestores=1 you will get a dump in the log of all assignments (and that includes definitions) as well as restores. You will not get the full definitions of macros though, just the first 32 tokens. If you want the full definition, you really have to hack the web source.

In there, matchtable[1] points to the "top" rule, which is "TEXT". The other key-value pairs in the table say roughly this: TEXT = an optional sequence [^0] of either footnote items [V("FOOTNOTE")] or non-footnote bytes [1], until the end of the data is reached [-1] FOOTNOTE = the string '\footnote', followed by optional space, followed by the footnote body. SP = zero or more occurrences of a space, tab, or newline byte BODY = a left brace, followed by an optional sequence of four possible things: 1. the string "\{" [P("\\{")] 2. the string "\}" [P("\\}")] 3. a byte that is not "{" nor "}" [(1 - S("{}"))] 4. a recursively included braced body [V("BODY")], followed by a right brace. The [/print] runs the print() command on each successful FOOTNOTE match.
