Hi, so I'm posting this last message to share the "final" version of the Label Table command; of course it is very rudimentary and would need additional work, but for me it does exactly what I need, so maybe it can be useful for others too. I hope Haris or Allan like it and add something like it to the Latex Bundle in the future (who knows what's in the mind of masters anyway).
I guess it is not possible to attach files from the web gmane interface, so I am posting the command inside the text. After all it takes 2 minutes to join back the long sed commands into one line, copy and paste into the bundle editor... Input: entire document, Output: HTML file, scope: you choose.
The command creates an HTML window listing all the \label-s of the topmost open window (only one file at the time, sorry). Each label in the window is clickable, and clicking inserts text at the insertion point in the open TextMate window. If the label name starts with "eq", then \eqref{label_name} is inserted; otherwise, only \ref{label_name}.
Best way to use the command: launch it the first time, the HTML window opens; resize and put the window in a handy position; then never close it, when you need it just issue the command again (the window is refreshed and jumps over the other windows).
Thanks to Allan for help. Enjoy and improve, Piero
TEXT OF THE COMMAND:
# parse the file for \labels (plus two lines following them) sed -n -e "/\label/{=;N;N;G;p;}" | # separate labels from each other, the html way sed '/^$/d' | sed 's/^([0-9]*)$/<p></p>\1/' | sed 's/(.)$/\1<br>/' | # the following two sed commands must be on one line each! # do not insert spaces when joining lines # insert active javascript links: for equations (we want \eqref here)... sed 's/\label{eq(.*)}/<a href="javascript:TextMate.system ("/usr/bin/osascript &>/dev/null -e @tell app \" TextMate\" to insert \"\\\\eqref{eq\1}\" @ &", null);">\label{eq\1}</a>/' | # ... and for the rest (sections, theorems etc.: we need \ref) sed 's/\label{([^e][^q].*)}/<a href="javascript:TextMate.system ("/usr/bin/osascript &>/dev/null -e @tell app \" TextMate\" to insert \"\\\\ref{\1}\" @ &", null);">\label{\1}</a>/' | # I used @ instead of ' for escaping reasons - put the quotes back tr "@" "'"
