    I was just talking about a fun and largely forgotten feature of Joy+Horton vi elsewhere.

    * https://mastodonapp.uk/@JdeBP/116793159030149624

    You can see it here in Ritter vi on lines 83 et seq. of ex_vis.h . vi actually has three flavours of its 'open' mode, for cursor addressable video terminals, non-cursor addressable video terminals, and actual paper terminals.

    There's an as-yet unfilled niche for the retrocomputeristas with genuine ADM-3s or (as someone pointed out) TI Silent 703s and suchlike to do a YouTube video showing Joy+Horton vi in its 3 open modes.

      What is open mode?

      • JdeBP 5 hours ago

        Fortunately, I don't have to write up an explanation of this, as Joy and Horton already did.

        * https://ex-vi.sourceforge.net/viin/paper-7.html#section53

        It's basically the answer to the question of how one does vi-like visual editing when the cursor cannot be moved to arbitrary locations on the terminal, or sometimes cannot even be moved upwards.

        Amusing factoid: It's actually sort of the other way around. open mode was added to ex before visual mode was. visual mode is the answer to the question of how you can take advantage of an ability to move the cursor around arbitrarily.

        VIM and STEVIE never implemented it. VIM makes :open do the same as :visual . nvi and nvi2 issue a 'not implemented' error for the :open nex command. Watcom vi does not even have :open . Nor do NeoVIM, nextvi, neatvi, and viless.

        Mortice Kern vi has open mode. So does elvis version 2.

      As an undergrad around 1984 I stumbled on some AT&T 3B2's in the computer lab and started to play. Knowing nothing of Unix (would have been ~ SVR3.x), I asked for help and the TA said something like "read the fine manual" as was customary. So I started off with "man something" and off we went, ending up at "man 1 vi", the glorious, pure original, none of this vim stuff...

      Of course when I got onto the BSD VAX, someone set me straight and it was Emacs from there on..

        Tangentially related, I wish more websites and blogs looked like this now. It's elegant and modern but simple.

          I wish it took up more than 640 pixels on the left of my 1920 pixel screen. I changed the CSS of the body to be 900pt instead of 480, and it renders at 1200px wide, which looks a lot nicer to my eyes. Didn't bother trying to center it though, which would have improved it even more

          • himata4113 12 hours ago

            Lacks centering, other than that I also found it enjoyable to look at.

            • deadbabe 8 hours ago

              That’s a feature. It lets your thumb scroll comfortably in a larger blank area so the content is always in view for you. There is no reason for things to be centered, it does not aid readability.

              • lunar_rover 7 hours ago

                This only works on large enough tablets. On phones the page isn't readable without a 3x zoom.

                • himata4113 8 hours ago

                  Not a feature on a 32inch ultrawide.

                  • deadbabe 8 hours ago

                    Use smaller window

                    • zamadatix 7 hours ago

                      Use phone horizontally.

                      Much more practically, the best designs are the ones who don't demand of the user they be consumed in a single form across every scenario.

                      • deadbabe 3 hours ago

                        Horizontal phones haven’t been practical for a while. The weight balance is off and you are forced to use it two handed. You’ll look like a toddler.

              • christophilus 11 hours ago

                To me, the justified text makes it an effortful read.

                • Gualdrapo 11 hours ago

                  Yup, I hope every one agrees to leave proper justified text to LaTeX/ConTeXt/Typst/<your_favorite_typesetting_software>, doing such thing for HTML is still ugly and makes things harder to read

                • nosioptar 10 hours ago

                  Breaks Firefox's reader mode.

                  Looks like dog shit on mobile.

                  I agree that this general style is good, just without some of this page's fuckups.

                  • kps 10 hours ago

                    Chrome's too, but why? It's just plain HTML.

                    • heftig 9 hours ago

                      Mobile browsers are assuming you're looking at a legacy page optimized for desktops (widescreen) and have a relatively large virtual screen size by default. They expect you to manually zoom in as necessary. Adding this helps:

                        <meta name="viewport" content="width=640, initial-scale=1">
                      
                      This matches the max-width specified by the CSS. However, a smaller viewport width might be appropriate to increase the text size on mobile.
                      • chorizo 9 hours ago

                        Safari reader mode on mobile works great. But then again, this is a site where you should not need it.

                    I started writing a more fleshed out vi compatibility mode for TextAdept earlier this year. As someone who understood the basics after going through :vimtutor multiple times but always struggled with the more "advanced" commands, there's no better way to actually grok vi than to just try to recreate it. It's pretty amazing how much Bill Joy managed to pack in. Of course, if you're implementing POSIX vi, there are quite a few features that have aged poorly, like roff/troff macros and line-editing, but there are also quite a few commands that I had never paid attention to (like _) that have subtle behaviors that sped up my editing even more. The hardest part about becoming proficient in vi is committing commands to muscle memory so you don't habitually fall back on hjkl.

                      What do you mean by "roff/troff macros"?

                      EDIT: Ah, you're probably talking about the "section-wise" movements, defined in POSIX with language like "A line whose first character is a <period> and whose second and third characters match a two-character pair in the 'sections' edit option (see ex)" - that's the first time I've stumbled upon the 'sections' and 'paragraphs' options in the Vim manual ... Very quaint!

                      A 2007 article from sourceforge.net and it's not even throwback Thursday.

                      "Gunnar Ritter <gunnarr@acm.org> 2007-11-29"

                        It's been years since I heard the term "Throwback Thursday", funny that reading it here felt like a throwback in its own right ^_^

                          It's still very much alive.

                        I wish elvis was still around. I don't want everything vim has but I like syntax highlighting and other conveniences

                            Is still around, at least for some values of "around".

                            Elvis, at its latest release (2.2.0) is a required part of Slackware, part of the A (essential system) package series. I have it installed on my system, alongside Plasma 6.7 and kernel 7.1.

                            • mghackerlady 4 hours ago

                              I suppose, but you can only install it via the AUR or nixpkgs on linux, and 2 out of the 4 BSDs no longer have ports. Sure, you can compile from source but when it's that old I consider such a state effectively no longer around

                          • whartung 6 hours ago

                            I learned vi back in the day and have never really graduated to vim.

                            My favorite features are the ranges on the commands (like substitute or delete), piping the buffer into the bottomless utility of the classic UNIX command line, and the . do again command.

                            About the only vim feature I use today is being able to navigate while entering text, but even after all this time, that is not automatic to me.

                            I have used syntax coloring a couple of times, I find it particularly useful for XML, especially XML with chunks of XML commented out.

                            • soraminazuki 35 minutes ago

                              On the rare occasions that I encounter non-Vim vi clones, I quickly run into missing features like these:

                              - deleting past the insertion point in insert mode

                              - visual mode

                              - split screen

                              - multiple buffers

                              - text objects

                              - macros

                              So even for people who don't care about Vim's syntax highlighting or autocomplete features, I'd assume real vi is a non-starter. I'd choose it over nano (no offence), but still.

                              • sawyers 5 hours ago

                                Any interesting reading on the second paragraph?

                                • whartung 2 hours ago

                                  I can't think of any, but I can share some examples.

                                  When shredding things like log files, or raw data file, being able to do things like:

                                    :g/bad line/d
                                  
                                  To delete all of the "bad lines". When manually paring down some files, you can use `ma` to do "Mark A" (vs `mb`, which is Mark B). So, I can be scrolling through the file, do the mark when I get to the top of a garbage section, and page or scroll or search to the next "keep" section, and then do `d'a` which means "delete to A", and so it removes all of the stuff I've skipped through.

                                  Doing simple things like:

                                     !Gformat (! to shell out, G for "the entire buffer", format is the program)
                                  
                                  Which runs the entire buffer through the `format` command to wrap paragraphs. I don't necessarily need that feature in my editor, I have a utility that I can use instead.

                                  Of course, you can use `!'a` to a mark. or `!/thing` to run current line to the next "thing" (use `?` for previous).

                                  Banging to utilities is a nice way to develop a pipeline, you basically get to see stuff step by step. So instead of:

                                      grep thing file | cut -f 1 | sort 
                                  
                                  You can vi the file, `!Ggrep thing`, "Yup!", `!G cut -f 1`, "Ok!", `!G sort` and easily see the intermediate steps. (Not recommended on enormous files, since the entire region is replaced.)

                                  The `.` is great for `/word` to find a "word", `cwnew-word`, and apply it selectively. `n` to "search next", and it you like it, `.` to do the `cw` again. Otherwise, keep using `n` until you find the one you like.

                                  And I have no problem running a chunk through a bang command to see what's what, only to just `u`ndo it. (With modern `vim`, you can undo that all the way back to the start if you're doing that pipeline thing.)

                                  And, I would routinely do something like:

                                    ma$%:'aw/tmp/x.x!vi other.txt then /wherever, :r /tmp/x.x
                                  
                                  Mark A, `$` to EOL, `%` to closing brace (imagine a C function header), write from mark A to current line to /tmp/x.x, `!` to shell out to a new `vi` session, then read in the snippet.

                                  Old school, single session, copy and paste. My /tmp is scattered with x.x, x.y, x.1, etc. files.

                                  Along with regex replaces, this is 95% of how I use `vi`. I'm sure there's a bunch of other features, especially in `vim`, but these few bits are flexible and powerful enough to cover my needs. Since I haven't really been found "wanting", I'm not really "looking".

                                  And it started because `vi` was a singular common denominator across all of the disparate UNIX minis I used to work on, so I just managed to work with what was available wherever I went.

                                  :x is a vim feature, so this wouldn't support it, so you'll have to use :wq instead.

                                    Incorrect.

                                    :x is a vi feature, that was introduced by Mary Ann Horton to actual Joy+Horton vi in February 1980.

                                    * https://code.illumos.org/plugins/gitiles/illumos-gate/+/refs...

                                    Ritter's vi is derived from Joy+Horton vi. Illumos has the original.

                                      Fascinating! I wonder what fork of vi I landed on that didn't have :x for me to have mis-picked-up that bit of trivia.

                                          ZZ is the first vi command I learned. After typing vi and only seeing a column of ~s, I asked how do I get out of this thing. Someone answered - ZZ.
