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).. -- Madhu ;;; PS: Here is a test case transcript, and also what to expect on the ;;; suggest fix : ;;; ;;; 1.
