jde-build suggestion: use C-u for args
I suggest that C-u C-c C-v C-b invert the meaning of the
jde-read-{make,ant}-args flag.
I often want to issue the same build command, but sometimes a
different one. So I set jde-read-make-args to t, but now I have to
press an extra key in 99% of the build invocations: C-c C-v C-b RET.
What do people think?

You mustn't copy the cedet.el file. Instead, specify the correct path in your ~/.emacs file. Inside Emacs, use C-x C-f and filename completion with TAB to find out which name to specify for the cedet.el that's part of your tarball. Kai

Well, there are installation instructions, but you don't say whether you read them or not. Also, you don't say what's failing. Did you install Emacs? Does it work? What was the next step after installing Emacs? How did you verify that this step worked? Which other steps did you take before things failed? When it failed, what did you attempt to do? What happened when you did that? What did you expect to happen? It isn't nice to answer questions with counter-questions, but I can't think of anything else that might help you. Kai

Investigating quickfix functionality
I had been using Eclipse for some time a year ago. One thing I really liked about it was the quickfix functionality. When the compiler found an error in your source code, you could hit Ctrl+1 to pop up a little menu which suggested some remedies. Because I missed it so much, I investigate whether it would be possible to get this in Emacs, as well. It seems it would be possible in principle. This version only knows two kinds of errors: unreported exception, and cannot resolve symbol class Foo. I'd appreciate any comments or help or patches. What do people think?

Well, adding mode inheritance would be cool, but having JDEE preconfigure align.el would be easy enough to do in the interim. Or should I ask align.el to be changed to know JDEE? Kai
Which buffer is compilation buffer created by C-c C-v C-b?
If I do C-c C-v C-b, how do I later find the *compilation* buffer created by the command? If I do M-x compile RET, then I can access the variable next-error-last-buffer. Kai

I verified that the same thing happens with the test case in my environment. I didn't realize that one has to compile both *.java files to make it work. So now I need to work on getting a test case that demonstrates the problem: the problem still happens with the real code that I'm editing. One difference between the test case and the real code is that the real code is compiled, jared (jarred? jar'd?) and the *.jar file is in $CLASSPATH. But the *.class files are NOT in $CLASSPATH. Another difference is that the real project has a prj.el file whereas the test case didn't have one. I'm sure that this is pilot error; I just don't know what I'm doing wrong. Kai

Now I get "no completion". The environment variable $CLASSPATH starts with ".:", and Action.class is in the current working directory, together with Action.java and BTest.java. But this was just a test case, in the real code that I've got, I see the same behavior I described originally, even though the code has been compiled many times on this machine already, and a corresponding *.jar file is mentioned in $CLASSPATH. Originally, I thought that the problem comes from the "import foo.*" statements in the *.java file -- I normally don't use asterisks in import statements but the author of the file in question doesn't want me to expand them. Then I made this test case and observed the same error. What can I do to track down the problem? Something weird must be going on, but I don't know where to start looking. Kai
jde-complete generates imports I don't want
Create a file A.java with the following contents:
public class A {
public static int main(String[] args)
{
A a = new A();
a.@
}
}
Position point on "@", delete the character, then hit C-c C-v . and
observe how it adds "import org.apache.ecs.xhtml.a;" to the beginning
of the file.
Or this one: create a file Action.java that looks like this:
public class Action {
public int foo() {
return 42;
}
}
Then create a file BTest.java that looks like this:
public class BTest extends Action {
public int bar() {
return this.
}
}
Then position point after "this." and invoke jde-complete (in one of
its flavors). Observe how it adds an import statement for
javax.swing.Action.
Is it pilot error?
Is it just me?

This functionality is a good thing. However, I'm a little bit afraid that people reinvent the wheel in lots of places. For example, why shouldn't C programmers be able to take advantage of this? There is a package in Emacs already that allows paired insertion of parentheses. Maybe it is sufficient to augment this package with doing newline and indentation? "(autotype)Inserting Pairs" is the right info node, I believe. Hm. Of course, your functionality is different: you pair the brace only on the subsequent newline. Hm. So maybe skeleton-pair is not the right feature after all. But still, why shouldn't other programmers also benefit? Kai

Foo completes to FooBar, FooBar( gives a list of constructors for this class. Replace M-TAB with whatever key you use for completion. Kai
C-c C-v C-z adds many newlines
I open a file ~/tmp/foo.java and type the following into it:
// begin file
package tmp;
public interface foo
{
public String frob() throws IOException;
}
// end file
The package line is the first line in the file, and the } line is the
last line in the file.
I position point on the word IOException and type C-c C-v C-z RET.
Here is the result:
// begin file
package tmp;
import java.io.IOException;
public interface foo
{
public String frob() throws IOException;
}
// end file
There are now three empty lines after the import statement. When the
package statement is missing, no empty line is inserted by C-c C-v
C-z.
How do I tell JDEE to insert fewer than three empty lines? One is
enough, IMVHO.

Looking for traditional alternative to C-c C-v C-.
C-c C-v C-. displays a popup menu. C-c C-v . does cycling completion. But I prefer the traditional method for completion that's more like TAB in the shell: completing once inserts a substring of all possible completions. Completing again shows a *Completions* window listing the possibilities, then entering another character to disambiguate and completing again will insert more substrings. Is this possible with JDEE?

Re: O.T. Regexp question
"Tim Werner" <[EMAIL PROTECTED]> writes: > I want to open the log file with emacs, and do a > "search-forward-regexp" to look for lines that do NOT end with "same > date". It turns out that I am too stoopid to figure out how to > construct the correct regexp. IMHO it is better to use another Emacs feature to do what you need. For example, you could delete all lines that end with "same date", using the flush-lines command. Then all remaining lines are the ones you're looking for. Or, you write a function that looks if the current line ends with "same date". If not, then stop, else go one line forward and repeat. If it MUST be a regexp, then the idea behind it is this: a line that does not end with "same date" is a line that does not end with "e", or a line that ends with "e" but the character before that is not "t", or a line that ends with "te" but the character before that is not "a", and so on. Here is a beginning to express this kind of logic: [^e]$\\|[^t]e$\\|[^a]te$\\|... You may have to add some rules for lines that are too short. The above logic would not find the line "ame date", for example, because it expects a character before the "ame date". Of course, ^$\\|^.$\\|^..$ will match lines of up to two characters, but no longer lines. Kai

The macros let you write > and mix individual analyzers in a convenient high-level way. My understanding was that Common Lisp has a configurable reader that is flexible enough so that one does not need to use lexers. Is this true? I wonder if it would be a workable approach to augment Emacs to have a better reader, then to use that as the lexer. I don't have practical experience with building parsers. Theoretically, one wouldn't need a lexer, just something that returns the next character from the input would be sufficient and the rest could be done from the grammar. (I mean that one doesn't need lex and could do everything in yacc instead.) But that makes parsers difficult to write, and also probably slow. So one does need lexers. But the theory seems to imply that the lexers don't need to be all-powerful: if the lexer is too stupid, then one can still do it from the grammar. So would it work in practice to "just" use an augmented Lisp reader as the lexer? Kai
JSP completion
I had a quick peek and found out that JDEE uses bsh to find the completion for some classes. So in theory it ought to be possible to kludge it so that it first compiles the *.jsp to a *.java by invoking Tomcat (say), and then have it compile the *.java, and then bsh can do its thing. Right? How would one go about this? I apologize for claiming previously that JDEE wasn't able to do completion in JSP files. Shame on me. Kai

Make imenu more appropriate for interactive use?
I have bound C-c m to the imenu command. My idea was that I do C-c m on a method and then jump to the definition of this method. But, with JDEE installed, and thus Semantic installed, I instead need to do: C-c m invoke imenu c RET invoke "Classes" TAB RET select the only item, "class.Foo" m RET invoke "Methods" .foo TAB RETselect the foo method I'm glad that I have partial-completion-mode turned on, for otherwise that last line wouldn't have worked. I'm also glad that method return types usually don't contain periods in my code, for in that case my method would have failed, too. However, I like the Speedbar display with the submenus. Can I have the cake (better M-x imenu RET interface) and eat it, too (keep the Semanticized Speedbar display)? Like I said, when point is on a construct such as "foo()" or "x.bar()", then IWBNI M-x imenu RET selected foo (or bar) as the default method to jump to, so that just hitting RET goes there.
