cl-lexical-let?

cl-lexical-let?

[Stephen Leake]

I'm updating jdee for emacs 25.

It uses the `lexical-let' function from cl, so I'm looking to replace
that with something, but there is no `cl-lexical-let'.

Here is a typical use:


(defun jde-jeval-cm (java-expr &optional buffer-head finish-fcn)
...
       (lexical-let ((finish finish-fcn))
	  (setq compilation-finish-functions
		(lambda (buf msg)
		  (funcall finish buf msg)
		  (setq compilation-finish-functions nil)))))
...


I think if I set lexical-binding t for the file, and change this to "(let
...", then this will work. Is that correct?

Is there any other replacement, if for some reason we don't want to set
lexical-binding t?

Yes.

Hopefully, there won't be any strong reasons not to set it.

State of Java support in JDEE, was: Re: cl-lexical-let?

Hi again, Stephen,

Since you doing this, you probably know: is there any kind of support 
now for language features of Java versions above 1.4, in JDEE?

 From what I've read before, it uses BeanShell (for completion, at 
least), and the latter didn't support generics.

Java 7 added a "smarter" type inference for generic instantiation; Java 
8 added lambda functions. It seems that JDEE should have even more 
difficulty handling modern Java code.

Any news there?

Thanks in advance,
Dmitry.

Not yet, but there is now interest in adding that.

JDEE recently moved to a git repository on github
https://github.com/jdee-emacs/jdee , and several people have expressed
interest in working on it.

Yes. The plan is to replace that with clojure.

Terrific, thanks for the news.
