That's true, it fixes only the execution path, not the arguments. So it does not help in this case. What I do usually with portable scripts is calling 'pil': #!/usr/bin/pil @lib/too.l or #!/usr/bin/pil -load "@lib/too.l" foo/main.l etc. > > The other escapes, like character attributes, line clearing, show/hide > > cursor > > and switching between first and second screen are more or less just > > cosmetics. > > Ok, thanks, maybe I understand that somehow now. > > If you do a (horizontal) split, then 2 +Window objects refer > to the same +Buffer object, so changes are synchronized. > The split is realized by dividing the current window hight by 2, > adjust the existing +Window object, and create a new one.

Ok, thanks, maybe I understand that somehow now. If you do a (horizontal) split, then 2 +Window objects refer to the same +Buffer object, so changes are synchronized. The split is realized by dividing the current window hight by 2, adjust the existing +Window object, and create a new one. Vip itself than draws the separating status line for each window (except the "mini buffer", in Emacs terminology). So its really just PicoLisp drawing on one terminal screen, not much vt100 "intelligence" involved.

The windows are maintained by Vip directly and explicitly. Simply positioning the cursor and writing stuff. Windows are just areas on the screen like everything else. As you see in @lib/vip.l, it uses only one single escape sequence for all such positionings: (de cup (Y X) (prin "^[[" Y ";" X "H") ) The other escapes, like character attributes, line clearing, show/hide cursor and switching between first and second screen are more or less just cosmetics. > On an up-to-date ArchLinux today, with the freshly downloaded dev > version of PicoLisp: > > [tj@arch picoLisp]$ (cd src64/;make) > /mkAsm x86-64 ".linux" .s Linux base "" ../lib/map version.l glob.l > main.l gc.l apply.l flow.l sym.l subr.l big.l io.l db.l net.l err.l > sys/x86-64.linux.code.l > Exception in thread "main" java.lang.UnsupportedClassVersionError: > PicoLisp : Unsupported major.minor version 52.0 It seems to fall back to Java because it finds no existing picolisp.

Oh, sorry! The article is outdated in this regard.
The Vip REPL now no longer behaves this way (triggering evaluation with an
opening parenthesis). Instead, it needs ": " (a colon and a space).
Practically, you get the colon by pressing ':' (as in Vim) or . At this
point you can enter commands like "e" (edit), "w" (write) and so on (see the
full list in the 'command' function in the 'case C' body. BUT if you press
a(nother) space here, the rest of the line will be evaluated.
This is easier than it sounds ;)
Try this: Hit '-' a few times to get a bigger command window. Then hit space,
space,(+ 3 4 and . The command window shows
: (+ 3 4)
-> 7
The focus is back to the current edit window.
Or, you move to the command window permanently with "qj" or "^wj", and edit
expressions manually. You can (re)evaluate any line there by pressing on
it.

Not a region (in the sense of as part of a file), but you can evaluate ('load')
the whole file by pressing F7.
Or you copy some lines to the command window ('y' and 'p' commands) and evaluate
them there.

Re: Vip without [N]curses
By the way, I wanted to clear a misunderstanding I seem to be having, regarding code evaluation in Vip. The wiki article says, that if I move to the command buffer and enter a Picolisp expression on a line of its own, then I can execute it by pressing Enter. So what I did was, I entered the following command: (out "/tmp/vip-test" (prinl "test")) And pressed Enter with the cursor on that expression. Based on the article, I would expect the code to be run and the /tmp/vip-test file to appear, but it didn't. Am I missing something? While I'm on the topic, is there a way to evaluate arbitrary Picolisp code from *any* Vip buffer, i.e. sending region to the Picolisp REPL?

The only place where @lib/vip.l calls 'align' is in 'status' (that's why you get the inverse video): (need (- *Columns (length A) (length Z)) " ") So it looks like *Columns is not set. Vip fetches it with (setq *Columns (format (sys "COLUMNS")) *Lines (format (sys "LINES")) ) I think in your environment these variables are not set or not exported. ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
Re: Vip without [N]curses
I know, but the invocation I mentioned worked for me before. The invocation from your email doesn't work either. Same error as before.

You can either call it from the REPL $ ./pil lib/vip.l + : (vi "file") ... : (vi 'car) Or make a startup script.

Re: Vip without [N]curses
Hmm... When running Vip (both with and without "+"), I get a reversed video Picolisp prompt. When I exit with a (bye), I get the following error message: [/usr/local/bin/vip:6] !?

Re: Vip without [N]curses
Great news! I also found it increasingly annoying, even on the user side, that on various systems getting Vip to run correctly was not always easy. Giving it a try right now.

Vip without [N]curses
Hi all, more and more I got frustrated with all the quirks of Ncurses (as discussed here and in IRC), so I decided to abandon them, and implement Vip directly with ANSI escape sequences (VT-100). To my surprise this turned out quite easy, and the result is both smaller and simpler! I tested on Termux, Tmux, XTerm and Linux Console. If anybody is interested, it is in the rolling picoLisp.tgz release :) ☺/ A!ex -- UNSUBSCRIBE: mailto:picolisp@software-lab.de?subject=Unsubscribe
