Thanks for the patches, Michael. ME> find-function-noselect blindly strips the last four characters ME> from the filename; but the filename might end only in ".el", ME> or in no extension. Actually it only does/did this for the recorded names of compiled functions, but you're right and I will fix this in the next version. However in XEmacs-21-beta with all function definitions now recorded in `load-history' the current version of that code is probably already redundant? ME> (The real problem is that evaluating a defadvice form (via ME> eval-expression or similar) for a compiled file changes the ME> return value of (compiled-function-annotation def) to ME> "loadup.el".) It does? I am aware of problems of using `find-function' with adviced functions. It is mentioned in the to-do list: however I don't have a good solution for this. Again maybe this problem has also been solved in XEmacs-21-beta by `load-history'? ME> The second chunk of this patch improves the error message when ME> the definition can't be found in the particular file where it ME> was searched for. Thanks. This will be in the next version. -- Jens-Ulrik Holger Petersen <http://www.kurims.kyoto-u.ac.jp/~petersen/> Research Institute for Mathematical Sciences, Kyoto University
