Ctrl-[ is mapped to escape by default in vim, which means no annoying rebinding of esc on your os (leaving capslock free to be mapped to ctrl, as G-d intended.)

[@damian_madmansnest]

The whole point of rebinding Caps Lock to Esc is that you have a quick way to escape to normal mode which you do often in vim. C-[ is hell of a convenient combination to press often. And i wonder what on earth do you need to remap Caps lock to Ctrl for? Emacs?

[@ianpan0102]

Vim emulation with bindings in favorite IDEs is a really good thing. It's the best of both worlds, you have all the powerful abilities of Vim and the great tools of you IDE.

I've learned vi's precursor ed in the Old Days(tm), when Curses terminals weren't common yet. vi, nvi, and then vim, were huge improvements in terms of user-friendliness. But even today, I still use ed (or vim in ex mode, just start vim with its alternate name ex) when dealing with extremely low-bandwidth or high-latency connections. Configuring those remote machines with ed/ex is extremely snappy, compared to anything fully visual like vim. Oh, and of course sed(1) rules as well. This may seem like a very exotic use of vim, but hey, thank $DEITY that ed/ex mode is still around. Great to see a vim lecture on KZbin in 2020.

vim have normal mode not because "this is whole new world and programing language", but just more pragmatic reason. There is not enough hotkeys(reasonably ergonomic hotkeys) if you keep letters to work as text input. That is why you need to have modes.

[@daleowens7695]

Even if you decide not to use VIM, learning the navigation keybindings are still pretty useful. I suppose more accurately I could say ex-normal mode is what I'm talking about here. Off the top of my head the less, man pages, git log output programs support VIM navigation bindings including search, eg. '/' or '?'. I'm sure I'm leaving out dozens of programs. Pretty much most Linux tui programs support VIM style navigation.

[@daleowens7695]

[@marksmod]

does someone know if one can map caps-lock+key (for example caps-lock+"f") to Escape, without X11 keyboard shenanigans (see sidenote at bottom of post)? That is, directly in vim or emacs? [sidenote] (you can set caps-lock to mod4 and then map the mod4 level to certain keys, but for who knows why not to escape and other special characters. I use a programmable keyboard, a vortex keyboard, to map Caps-lock+"a" to mod4+ctrl, leaving all other keybindings still intact, so for example if you bind mod4+l to left-arrow key, and then press mod4+"a"+"l" at the same time (not a chord) then it would be synonymous to pressing ctrl+"left key", which is, in my opinion often times faster than allot of the vim or emacs chords. I also bind mod4+"x" and mod4+"c" to "end" and "home" keys. Oh, and things like Shift+mod4+"a"+"l" are also possible which would be synonymous to Shift+ctrl+"left arrow". This alone enhances "edit mode" for me considerably, though it doesn't quite suffice for moving very quickly between parts in a single document, language dependent )

[@TehGettinq]

Idk if that will help you, but on ubuntu in the settings theres a one click option to literally remap escape to caps lock. Its not a vim thing in this case but a distro thing, they put it by default because they know that the escape key is far. Btw for vim you can use ctrl [ (thats the same as escape and thats the most "vim thing" to do to) but i find having caps lock as escape is nicer, also useful outside of vim.

[@astropgn]

I am of the opinion that the editor matter less than what he conveyed at the beginning of this lecture. One thing is to try to write code in programs that have very few features. Another thing is to compare full feature editing tools tuned to the sole purpose of writing code. Yeah, efficient people who uses VIM do it very efficiently... so as efficient people writing in visual studio or their favorite IDE. I didn't buy the argument that at 20 hours will get the same speed and then forward you will see improvement. We see improvements on every tool we have expertise. The one argument in favor of vim, in my opinion, is to be able to efficiently work when you cannot control the environment. If you write a lot of code remotely on the cloud, for example, or if you have to access someone else's computer but they don't have the software you use. Otherwise, you can get the same level of optimization with any other editor. Whenever I see someone saying that it is inherently more efficient and practical to use vi, I think it is just confirmation bias .

[@TehGettinq]

You will definitely edit text way faster in vim/nvim than in any other editor/ide. Its not even close to being comparable. Does it matter? probably not really.

[@astropgn]

​@@TehGettinq I don't think it is an easy statement to accept. First, people can get very proficient with their set of tools. Blind people using assistive aids can navigate through their phones as fast as non blind people for example. So it could be, at least theoretically, that very proficient vim users do as well as an equivalent non vim user that are also experienced users of their set of tools. Hard to know for sure, but also hard to deny it as well. It is hard even to test this. Yeah, one can show a workflow where vim is incredibly faster than any other method... But nitpicking a couple or dozen of cases while ignoring the entire universe of cases the industry demands does not prove anything. Another way to think about it is that the market tends towards efficiency of resources. If vim was really that much better at delivering productivity, the market would tend to make non vim editors obsolete (no company uses punch cards anymore). This does not happen. What we see is a spectrum of tools used by a spectrum of users. This makes me believe two things: First, many of these tools could each one be better at specific set of tasks, but none being better overall, and second, the cost of learning and getting experience with a specific tool might damage productivity as a whole, which makes the industry tends towards an equilibrium between users that use vim and users that don't. This would explain the distribution and there would be no reason to argue in favor of one or another like that. In either case there is no indication of superiority.

[@Qladstone]

​@@TehGettinqYou may be able to edit text faster, but can you do full-scale refactoring with IDE scan for usages, instant creation of getter/setter methods, step-debugging with live evaluation of arbitrary expressions at any line you want, instant scroll of all usages of a method/variable/class, alongside many powerful features of a commercial grade IDE like Intellij IDEA? Maybe you could configure all of those things, but surely not in 20 hours. More like 200 hours of trial and error and frustration probably, and still not get the desired effect. Not to mention you can do pretty much everything in IntelliJ IDEA with keyboard shortcuts. I pretty much never have to touch my mouse when using IntelliJ IDEA.

[@TehGettinq]

@@Qladstone yep, can do.

[@leonardopikachu343]

Alright, i still don’t understand why this will make me more efficient editing code, compared to, say, sublime.... or compared to using a mouse..... i get it if you are in a Linux system and vim is the only editor available... but if you are using a Mac or windows machine, why vim?

[@rhaeyx1076]

In my experience, using vim with touch typing would increase your efficiency by a lot. It takes time to get used to it though. But as you spend more time programming, you get kind of annoyed when you need to reach for your mouse or the arrow keys to select something a few lines above, because with vim you can just switch to visual mode and use the hjkl keys to navigate which are keys that are already near your fingers.

[@Duiker36]

Tbh, the differential isn't worth it. Vi users tout the "code as fast as you think" bit as a selling point, but the truth is that most programmers need to learn to think and type slower, not faster. The real value of Vi (or Emacs or Nano) is that virtually every standard server will have it. Pushing mouse inputs through an ssh tunnel to the other side of the world is inefficient at best, and the weight of a graphical interface makes it non-ideal. And even that is less and less of an issue, because editing a file on a server probably suggests you're doing something wrong, and as the industry's standards have improved, the need is just rarer and rarer. I personally use vim because that used to be a real concern (a company I used to work at preferred us all work off development environments located on company servers, so you'd have to ssh in to do anything to begin with), and now it's just a habit. The real takeaway that I feel this class didn't advocate strongly enough for is this: pick your tool, and learn it well. If it's vim, great. If it's vscode or intellij, great. Learn its quirks, how it thinks, why it makes what choices it does, how to get it to do all sorts of stuff. And also learn its limitations. Vim will always be terrible with a visual programming language, for example. But the point is that, if a tool is in your toolbox, be good at the tool. But pick one. It doesn't have to be the best. It just has to be _your_ best.

As you learn more, there are things that are far more efficient in vim, Sorting code, putting variable s into columns, removing duplicate lines, recording macros and say a couple keystrokes to repeat that macro a thousand times. Plus most text editors don't have a dictionary built in, the ability to add a thesaurus, there are allot of things that other editors just don't do well, or at all. But it depends on how somebody uses it, if they use it like a regular text editor and don't learn the features, there probably won't be much benefit.

32:19, "And that can select rectangular blocks of text. So I bet this is something your old editor couldn't do" Actually, vscode has that (in two variants). Holding down the middle mouse button allows for rectangular block select, and `ctrl + shift + alt + arrow key` is a multicursor select (not sure that's a default keybinding). Multicursor select is really useful, because you can edit multiple lines at once. I find it really useful for editing parameters to repeated function calls, or lining up code vertically

Yes. Vim minimizes the time between realizing what you have to change in the text and having it done. When you ‘get’ vim you start looking at your edits as precise tactical actions. You become confident knowing that the changes you’ve made are exactly what you had in mind. Next time you mash the same keys a few times to put your cursor where it needs to be or reach for the mouse to select precisely the portion of the text you need to overwrite know that vim would almost certainly give you a more efficient approach of making the same change.

VS Code has vi emulators. One reason I believe is the plain existence of the default "normal" mode of vi: the browsing mode being the default. I use vi, VS Code, Visual Studio and Intellij Idea for many reasons. Sometimes in the same day. And today is normal to have many --- really many --- files open at the same time and the way all these modern editors do is that if you press a key it goes into your file. Period. File is changed. And many times a file gets changed by mistake, because I just typed in the wrong window. Sometimes it goes up to git repositories :). And there is no easy way to protect a file. It is easy when you are just reviewing a file for some reason, a demo, a conference maybe, and the file gets changed by mistake. Programmers not always want to change a file. Other thing a miss in the other editors is the Z commands, for precise cursor positioning. When looking up for a string just to key in /string the cursor goes to the point. Then z- and the line is the last on screen, Z. it goes to the middle, Z enter and the text scrolls so the line is the first on screen.

So, here is the deal: I like the idea about learning vim and all that it has to offer, but for an intermediate or beginning programmer it is probably not as useful. One major thing that other editors like VS Code or Atom offer is code autocompletion. And I know what you're going to say: this too is available in vim. Yes, I know, but I just spent way too much time trying to install that and still ended up without this feature because I got stuck with the stupid installation instructions for Vundle and pathogen when I tried to install jedi-vim. Why is it so complicated? In Atom or VS Code it's already there, especially if you have Kite. This is my 3rd or 4th attempt at vim and I keep getting discouraged. I might give it another shot sometime later if I'll need to write a book or something.

[@Aqueelzalla]

I had the exact same experience... tried couple of times but couldn't get autocompletion work...

[@glzr_io]

Use the vim extension for VS Code and you get the best of both worlds

[@GwenHrothgar]

Or don't use autocomplete and practice memorizing and typing faster.

[@TehGettinq]

@@GwenHrothgar thats retarded and leads to errors. Its a bad idea. Typing faster isnt an issue.

[@rumble1925]

It's not that useful honestly. I work with guys that use vim emulation, and they constantly mess up which mode they are in and mess up chunks of code. They never use the vi language features in any way that is more complex than what you'd do in a normal text editor. Vim is super powerful... but for writing code it's overkill. I'm way faster in VS Code because I don't need to keep track of anything in my head, I just edit the code as it is on screen.

@@almasfizashaikh6159 ya :q is the standard methods of exiting vim, there are two other methods which I know are :wq and :q! or :qa!. :wq saves the file and quits the Vim window (:wa lets u save and keep working), :q! and :qa! are not recommended though :)

[@TehGettinq]

@@your_name96 :q! is recommended and very useful. it means you can exit the file without saving changes. Aka edit the file and ignore changes.

[@Yotanido]

@@your_name96 There's also :x, which does the same as :wq. (Well... :x only saves the file if it was actually changed, while :wq does a write even if it is unchanged. This will only be relevant in very niche cases, though)

@@БарометрАтмосферный Vim is by far not the most minimalist text editor; Vim is a very big one. Smaller text editors are, for example, ed(1), ex(1) and sam(1).
