Re: New Emacs-style command-line editor
Hi Alex, Are the arrow keys usable on the phone? Both the vi- and the emacs-style command line in PicoLisp now also support arrow keys for navigating the history. Yes, they work great. One less keypress. Great! Thorsten, Alex - Would it be possible to add hooks to the emacs line editor? I came up with a rough patch to demonstrate what I mean. I wanted to minimize the number of changes to eled but had some problems due to needing to reference the transient symbols. Also, I'm still pretty basic when it comes to my understanding on the best way to do things. In any case: Change #1 - lib/eled.l add a hook to the front of the insMode case list (de insMode (C) (if (= C ^I) ... (case C ~(car (list *EmacsKeyHook)) (^? Change #2 - lib/eled.l add a method to wrap the transients and invoke a block (de EmacsHook Prg (let (_Line Line _chgLine chgLine) (eval (car Prg ))) ) From these two changes, I can inject my own functions such as this one to automatically close parens Let's say I have an init.l (de closeParens (Line) (let (Open (length (sect Line (list ( ))) Close (length (sect Line (list ) (make (for X Line (link X)) (for X (- Open Close) (link )) (setq *EmacsKeyHook '((^y (EmacsHook (let L (closeParens _Line) (_chgLine L (length L))) I can then run: /pil init.l -em + : '(a (b (c Ctrl-Y and have it automatically close my open parens I'm sure there's other ways to do this but wanted to share the concept Thanks again for the new feature Joe

It works very well on my phone too which had some trouble with the terminal program switching in and out of vi mode due to the poor handling of Esc. I will definitely be using this Thanks for the feedback, good to know that it works for others too. In some cases there is surprising behaviour (like 'eating' the last char of the line after a navigation command), but thats easily changed. Please report, if you encounter 'not emacs-like' behaviour, I reused many of the vi-functions, and sometimes the semantics of the same command are a bit different in vi and emacs. I have spent the last year learning emacs and what I've found is (my personal experience, not a flame war) that emacs can be more efficient and natural when creating new content - either code or text. Vim is more efficient for me when changing large amounts of code or refactoring. That may come with time in emacs. I think both vi and emacs users are in the top 5pc of efficient computer users, so no real reason to worry if one is slightly better than the other in occasions. But since the concepts are so different, I would not want to change frequently between thinking in vi and thinking in emacs, so I did not even touch vi (and won't do so ;) did you know that: ,- | C-c v runs the command view-buffer, which is an interactive compiled | Lisp function in `view.el'. | | It is bound to C-c v. | | (view-buffer BUFFER optional EXIT-ACTION) | | View BUFFER in View mode, returning to previous buffer when done. | Emacs commands editing the buffer contents are not available; instead, a | special set of commands (mostly letters and punctuation) are defined for | moving around in the buffer. | Space scrolls forward, Delete scrolls backward. | For a list of all View commands, type H or h while viewing. `- I dired, you just type v instead of f on a file to open it in view mode. That nice if you want (vi-like ?) read-only navigation without messing up your sources accidentally. Just type e to make the buffer editable again, or q to delete the buffer. -- cheers, Thorsten -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
New Emacs-style command-line editor
Hi List, I just posted a reference article on the wiki (http://picolisp.com/5000/!wiki?emacsstyleled) that explains how to activate and use the new Emacs-style command-line editor developed by me (with some help from Alex). You can try it out with the new testing version 3.1.0.15 available on the download page. Feedback is welcome. The goal is that Emacs users feel right at home at the PicoLisp command-line - that its possible to switch between the REPL and Emacs almost without being aware of changing the application (like switching between Emacs and Conkeror). There is still some functionality to add, but it works already quite good, I use it all the time now. I would be highly appreciated if Emacs users could test it and report bugs. -- cheers, Thorsten -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
Re: New Emacs-style command-line editor
Thanks Thorsten! I will give it a shot. This gives me a reason to try emacs again for picolisp. I installed everything the other day and then switched back to vi and vi mode in the repl after getting frustrated with not knowing how to cycle through my command history in inferior-picolisp. I am so used to esc k j After some googling tonight I found how to cycle using - M-p (comint-previous-input) Select the previous command in the input history. - M-n (comint-next-input) Select the next command in the input history. It might be nice to add this and any other tricks to your emacs style page. By the way, if no one has tried it yet, ConqueTerm makes a nice alternative to inferior-lisp when using vim. I typically run it in a split. I've found the paren matching to be somewhat slow when it copies in the text so sometimes I'll just skip ConqueTerm altogether and map a key to run pil on the file I'm working on.

However, I found it very frustrating to be totally lost on the PicoLisp command-line (since I don't know nothing about vi). And I do think that the PicoLisp philosophy (live in the command-line, open an editor on demand) does have its merits sometimes. Therefore I wrote the Emacs-style editor. Its still alpha, but now I can use the PicoLisp line editor in a 'natural way' (for an Emacs user), just like I use the Bash command-line in Emacs mode without thinking.

Thats already implemented, but I used C-p and C-n instead of M-p and M-n since there is only only line in the REPL and and C-p and C-n can't server as line-up and line-down in a buffer. However, I could change that anytime.
