For example: say I jump to this function and want to fix a bug (the `search` should strip off the first two characters here, not just one). So I need to change `regex.search(s[1:], ...)` to `regex.search(s[2:], ...)`:
def compile_hg_glob(line):
pat = glob_to_re(line)
# Mercurial ignore globs are quasi-rooted at directory boundaries or the
# beginning of the pattern.
pat = '(^|/)' + pat
# Mercurial globs also have to match to the end of the pattern.
pat = pat + '$'
try:
regex = re.compile(pat)
return lambda s: regex.search(s[1:] if s.startswith('./') else s)
except:
warn("could not parse hgignore pattern '%s'" % line)
return lambda s: True
If I've just used a fancy shortcut key to jump to this function, my cursor is probably on the function name. In Vim, I'd do `cinr2:<esc>`. Seven keystrokes. I could also do `/[<cr><ctrl-a>` which is only four keystrokes, but a little more awkward to reach. If I tried to do this editing with arrow keys and backspaces I'd need 12 down keystrokes just to get to the right line.Or suppose I'm looking at this and want to add a `,` character to the end of each of the type entries, because I forgot Python likes its commas:
result = result | {
'a': TYPES_ALL
'e': TYPES_FILE_REAL
'x': TYPES_FILE_SYMLINK
'c': TYPES_DIR_REAL
'y': TYPES_DIR_SYMLINK
'f': TYPES_FILE
'd': TYPES_DIR
'r': TYPES_REAL
's': TYPES_SYMLINK
}[c.lower()]
In Vim I'd press `j` to get to the first entry, then `A,<esc>` to append the `,` after the first one, then `j.` to move down and repeat the action. I then press `j.` a bunch more times (which is really easy to do rapidly with your index and ring finger on Qwerty) and in 2 seconds I'm done. Vim's `.` to repeat the last action is really powerful and can save you a ton of time for small ad-hoc edit repetitions that don't warrant doing a full macro with `q`.These kinds of things happen constantly, and when you've got Vim burned into your fingers trying to edit text without it (actually edit text, not just jumping to something) feels like typing with oven mitts on.
I've seen many Vim/Emacs-only devs being easily beaten in speed by others using modern IDEs that have tooling and functionality (auto formatting, refactoring, templating, etc) focused on actually getting things done.
And I'm not talking about Vim the editor. I'm talking about Vim as an idea. Which is today implemented for pretty much every single [popular] editor and IDE in use. That fact alone is pretty illustrative of awesomeness of the idea of Vim.
And the comment about Emacs is quite disingenuous. I have never been inside a Formula One cockpit, but I can totally get "the job done" with my Camry, because it is totally more efficient for parallel parking.
I have used many IDEs, including InteliJ (which I used for about seven years). Emacs wins solely by its extensibility, no editor/IDE has ever matched its capabilities. For some people that is not an important factor, just like the efficient parallel parking might not be important for Formula One pilots. But when you can automate pretty much anything it feels very empowering and liberating.
Small example: when I'm about the create a new commit, an emacs-lisp script can figure out the current ticket I'm working on (based on currently clocked Org-mode task), generate a branch name based on the ticket description, generate part of the commit message (in the way that it is in compliance with git tool like gommit), I would just have to type the rest of the message.
That is not only more efficient, but also reduces frustration. Compare that with the workflow in any other editor and IDE - most of these steps will have to be manual. Then someone might say: oh there's actually a plugin for Editor X that does some of that stuff for Jira. But what if I join a different company that uses Pivotal Tracker instead? I can extend my emacs-lisp script. Whereas if that's an InteliJ plugin I would either have to go through daunting process of forking and modifying the plugin or submit a feature request and wait for something that may never happen.
Moving a little bit faster through the text file to edit characters is rarely the issue and I certainly wouldn't give up IDE features for it.
2: select the first :, ctrl+d until all are selected, right arrow, comma
Doesn’t sound any more efficient? Plus, who writes code without an auto-formatter these days? Problem two would have been solved by the linter the moment you wrote that.
Obviously the first part is language-neutral, and is exactly why I think multiple cursors is one of the greatest inventions in text editing! :)
Eh. I'd probably do 'qqA,<esc>j0q', and then '8@q'.
That's also probably not the best example, since that's also trivial if you have an editor supporting multiple cursors.
That said, I think multiple cursors are the greatest addition to text editing since, well, vim. I was an enthusiastic user of Sublime Text 1, right before I learned about vim.
Luckily, vim has multiple cursor support, which is... decent. Not great, but decent. I actually think that the only thing that makes multiple cursors more awesome, is being able to combine them with vim's commands, since multiple cursors rely on you being able to do precise things at each cursor, and vim gives you the language for it.
Yeah, it's hard to come up with a decent example because I don't even think about it any more, it's just burned into my fingers. I just know how excruciating it feels to edit without Vim (I even wrote that last comment in Vim and then copied it into the browser because writing it in a text field is miserable).
It basically gives vim-like keys anywhere you want, when holding down the caps lock key. So e.g. caps+h/j/k/l are movement keys.
It goes a lot farther than that: I have a key to delete a line, a key to select a word, a key to go up/down by 4 lines, a key to delete the last word, etc. I even mapped caps+f to jump forward 20 characters (to badly simulate using 'f [letter]' in vim).
This makes so it I never have to leave home position on the keyboard, because while holding caps I have all the movement keys I want at my disposal. It's a total lifesaver, and the only way I can effectively use a keyboard outside of vim :)
<c-v>8j$A,<esc>
The part about moving the cursor. Vim users typically don't move the cursor with the mouse but rather with the keyboard. Having to move your hands off the keyboard to reach for the mouse then back is the part that starts to feel sluggish if you get used to not doing it.
In a modern IDE you have a multitude of shortcuts and a mouse, and they complement each other.
Longtime vim users who didn't know how to use vim? That's... interesting.
Stock vim is mouseless, and without arrow-keys, which means relying on /? (searching) or other keys to achieve the function of arriving at text. CTRL-F never quite matches that (after you hit enter, the CTRL-F dialog is still open, and needs to be closed with ESC or by clicking away), and moving to the arrow keys/pgup/pgdown/mouse is slow.
Having said that - there are some plugins that match this behaviour - I particularly like the ones where a key (f in vimium) highlights each word with a character, allowing for one or two keypresses to jump anywhere on the screen.
- Go-to-definition is `g d` (with the cursor over the function name in question)
- Project-wide file search is `SPC SPC`
- Jumping to a function is `SPC s i` and then just start typing to fuzzy-match the function name
I stick with this setup because it does pretty much everything I could want from IDEA, and does it without churning up most of the resources on my machine. And trust me, I've tried to switch to IDEA, but it's just too big and too slow, and too poor of an editor for me to actually make the switch.
The one related function that I would miss is using vimgrep and the QuickFix list to get a list of the locations where the function name appears which I can use e.g. to do a search and replace in those files (or a subset of them)
E.g., say you somehow got to a file, and it now has a bunch of functions in it, and you're literally looking at the line you want to edit. To get to that line, there's a bunch of different ways, but you can do this in like 3 key presses. Then, within the line, you can change anything in it really easily.
This sounds weird, so I'll try to give an example. Let's assume you have something like:
Func(self._something, self.something_else).validate, 'Validate exam foundation table')
And let's say you want to change the string that says 'Validate [...]' to say 'Change is good!!'.
To do that, once you've gotten to the line, I'd probably hit two key presses that mean "go to the first open quote in the line", then I'd hit the keys that mean "delete everything inside of the quote character", then I'd type what I want. All in all, I'd be typing these characters before actually writing what I want to write: f'ci' (so, 5 characters).
That probably looks either idiotic or daunting - but the idea of vim is that it's a language - you are literally thinking in your head "go to that quotation mark", then tell vim to do that and it does. Then you're thinking "delete everything inside of these quotations", and it does it. The distance between thinking what you want to do and doing it is almost zero - it's as close as you can get to literally telling someone exactly what to do.
If you're using a non-vim editor, you'd probably have your cursos in the begining of the line, and have to do "cmd+right" several times to skip over words in order to get to the first word of the string, then have to "shift+cmd+right" to get to the end of the string, then write what you want.
There might also be some small annoyances - the last shift+cmd+right might take you over the last quotation mark, and you'd end up selecting the closing paren as well. In vim - that doesn't happen, you're saying exactly what you want to have happen.
Or you might want to undo this change - in vim, it's always hitting "u" once, because in vim, changing the string to something else is an atomic motion. In another editor, you might have to undo a few words at a time, or maybe not - it's not always predictable. And since it's atomic in vim, it's also easy to re-apply the same action to another string - so changing another string to the same thing is a simple matter of hitting "." on it.
And of course, this is just a tiny example. It's easy to dismiss as trivial or unimportant - these are tiny savings of time, after all, and even if you add it up, I doubt the "time saved" in doing things more efficiently is worth much.
But once you know this language for telling an editor exactly what to do, then using an editor that doesn't speak that language just feels super slow - it feels like you are not able to communicate properly, and suddenly, what used to be zero gap between thinking and doing, takes a long time.
Double-click the word to select it, and start typing right away.
> it's as close as you can get to literally telling someone exactly what to do.
I usually tell someone "Change the word 'validate' to 'something else'". SO i grab my mouse/trackpad, and get there in one click (or double-click).
> It's easy to dismiss as trivial or unimportant - these are tiny savings of time, after all
You should observe most of these "savings" in real life. There's rarely a time when I can't do stuff with code faster than a Vim user. Because by the time the vim user has typed the required sequence of letter, or counted which line/symbol/mark to go to, or wrote a macro correctly, I'll have finished all I needed to do using IDEs built-in capabilities and/or a mouse.
In vscode, I'm usually already looking at the call site of a function I want to edit. So I move the cursor into the function call and hit F12 which takes me to the function definition to edit it. Once I'm done, I hit Alt+LEFT to navigate back to where I was to continue on...
If I didn't start from a call site but I know the file I want to edit - I hit Ctrl+P, type the name of a file, hit ENTER - now I'm in the file, ready to edit it.
To jump to a function, I collapse all functions (Ctrl+K,Ctrl+0/1/2/3/4) and then scroll (or PAGE UP/DN) to find it...then use arrow keys or Ctrl+G to enter the line number. Now I'm ready to edit the function. I might have to hit Ctrl+Shift+] to expand the body of the function.
Alternatively, I Ctrl+F and type the name of the function I want to edit, pressing ENTER to find it...and I'm ready to edit the function.
What do you do in vim that is far easier?
