I've been working with Eric Ludlum to develop additions to semantic that will integrate the Java classpath with semantic. By this I mean, whenever you ask for information about a class, the JDEE will look first in the semantic databases on your system and only resort to the beanshell as a last resort. This will all be done transparently so tha clients of the semantic database, such as the JDEE's completion and go-to-symbol-def commands, never need to worry about where the class information is located. I've got a lot of the functionality implemented but have had to put the project on hold in order to make time to absorb a recent spate of JDEE contributions and also because of work deadlines. I expect to get back to this project in a few weeks. - Paul > Let me know what you think. > > > (defun jde-custom-find-fqimport (import-list class) > "Opens the source file for `class' if a fully qualified import statement > for > the class is found in `import-list' and returns t; returns nil otherwise. > Uses `jde-find-class-source' to open the file" > (let ((current-import) > (match-found nil) > (iterator import-list)) > (while (and iterator (not match-found)) > (setq current-import (car (car iterator))) > (message current-import) > (if (string-match (concat ".*\\." class "\\'") current-import) > (progn > (if (not (jde-find-class-source current-import)) > (message "Can't find source")) > (setq match-found t))) > (setq iterator (cdr iterator))) > match-found > ) > ) > > (defun jde-custom-find-starimport (import-list class) > "Opens the source file for `class' if a star import statement for > the class is found in `import-list' and returns t; returns nil otherwise. > Uses `jde-find-class-source' to open the file" > (let ((current-import) > (match-found nil) > (iterator import-list)) > (while (and iterator (not match-found)) > (setq current-import (car (car iterator))) > (message current-import) > (if (string-match "\\(.*\\.\\)\\*" current-import) > (progn > (setq current-import (replace-match "\\1" t nil current-import)) > (message "found star import") > (message current-import) > (if (jde-find-class-source (concat current-import class)) > (setq match-found t)))) > (setq iterator (cdr iterator))) > match-found > ) > ) > > > (defun jde-custom-open-class (&optional unqual-class) > "Opens the source file for `class' if an import statement for > the class is found or the class is found in the current source file > directory or in java.lang. > Uses `jde-find-class-source' to open the file" > (interactive) > ;; (semantic-bovinate-toplevel t) > (save-excursion > (let* ((class (or unqual-class > (read-from-minibuffer "Class: " (thing-at-point > 'symbol)))) > (tokens (semantic-bovinate-toplevel t)) > (depends (semantic-find-nonterminal-by-token 'include tokens))) > (cond ((jde-custom-find-fqimport depends class)) > ((jde-custom-find-starimport depends class)) > ((progn > ;; look for file in current directory > (let ((fname (concat class ".java"))) > (if (file-readable-p fname) > (progn (find-file fname) ; open file in current > dir > (message "Opened %s" (expand-file-name > fname))))))) > ((jde-find-class-source (concat "java.lang." class))) > ((jde-open-class-source class)) > ) > ))) > > (defun jde-custom-open-class-at-point() > (interactive) > (jde-custom-open-class (current-word))) > > > > > Tim Babin > > <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2//EN"> > <HTML> > <HEAD> > <META HTTP-EQUIV="Content-Type" CONTENT="text/html; charset=iso-8859-1"> > <META NAME="Generator" CONTENT="MS Exchange Server version 5.5.2654.89"> > <TITLE>Using semantic + import statement to open class source</TITLE> > </HEAD> > <BODY> > > <P><FONT SIZE=2 FACE="Arial">Hi,</FONT> > <BR> <FONT SIZE=2 FACE="Arial">I found the >java-open package written by Rajeev Karunakaran to be quite useful and quick.</FONT> > <BR><FONT SIZE=2 FACE="Arial">I have written some functions which use the same >concept but use semantic to get the import statements instead</FONT> > <BR><FONT SIZE=2 FACE="Arial">of reg-ex.
