Re: slime-complete-symbol* : I noticed that slime-c-p-c does not work correctly but can mangle text after a completion is chosen , [I'm appending a test case to the end of this message.]

I'm afraid I'm to blame for this, I think: the patch I submitted claiming to fix XEmacs behaviour (on 2007-08-04) and which was committed on 2007-09-04 is incorrect [ 1. the analysis is not restricted to XEmacs, and 2. Emacs choose-completion does not work right unless the text in the buffer is a proper prefix of the completions displayed. I cannot see any lowest-common-denominator solution for this.]

I would suggest reverting the patch. The downside is that you get back the original behaviour, which mangles the text BEFORE the completion is chosen: If you type "m-v" and hit TAB the function will delete your text and leave you with "m" -- because "m" is emacs' completed-prefix matching both "machine-version" and "multiple-value*"s. [This may or may not be acceptable, indeed whether it is what you want would depend on which buffer you are in, and what symbol you are trying to complete]

Apologies for the incomplete patch and the earlier noise over the [unrelated yet related] unambiguous-prefix issue (from 06)..

;;; PS: Here is a test case transcript, and also what to expect on the ;;; suggest fix :

;;; ;;; 1. First we recreate the situation in acl, where there are multiple ;;; completions for "l-p-t". ;;;

CL-USER> '(locale-print-time logical-pathname-translations logical-pathname-translations-database-pathnames)

(LOCALE-PRINT-TIME LOGICAL-PATHNAME-TRANSLATIONS LOGICAL-PATHNAME-TRANSLATIONS-DATABASE-PATHNAMES)

;;; ;;; 2. slime-c-p-c-unambiguous-prefix-p is set to nil ;;; BEFORE:

CL-USER> l-p-t ;;; ^^^ hit TAB, then choose the logical-pathname-translations ;;; completion in the *Completions* buffer

;;; AFTER: The completed form looks like:

CL-USER> (l-plogical-pathname-translations

;;; ;;; 3. Next try after setting slime-c-p-c-unambiguous-prefix-p nil ;;; BEFORE:

CL-USER> l-p-t ;;; ^^^ hit TAB, then choose the logical-pathname-translations ;;; completion in the *Completions* buffer

;;; AFTER:

CL-USER> (logical-pathname-translationsp-t

;;; ;;; 4.WITH 2007-09-04 PATCH REVERTED: ;;; BEFORE:

CL-USER> l-p-t ;;; ^^^ hit TAB, then choose the logical-pathname-translations ;;; completion in the *Completions* buffer

;;; AFTER:

CL-USER> (lo ^^^ note that the text you input is gone.

;;; but at least choosing a completion won't mangle the text in your ;;; buffer
