I usually use 1.5 myself but 1.75 would prolly work. It sounds like people are drunk when I watch at 1x. It gets rough when Prime goes to 1.5x himself cause now I'm watching what he's watching at 3x. Prime is already a fast talker too. About the only thing i dont like about watching at a faster speed is when videos pop something on screen ans it goes away so fast.

BRO EXACTLY I just commented that, this is a 30 second problem for a analyst using excel, but it would take me a week until I figure out how to do it using vin and coding coding regular expressions What sucks is that using Excel it will not be scalable. My first thought was to split each character in a cell line, in the next column do the same but moving the characters 1 position up, same for the next 2 Columns, 5th column concatenate line coluns A...D, 6th column the line number last make another sheet, character aaaa to zzzz and make a Procv on sheet1 F:F (6th column) There, you got all the situations where it happened and where it happened

Tip: You can use :v instead of :g to run the command on every line that doesn't match. So instead of using the \@! thing, you could just do :v/\d/d also :v acts the same way "grep -v" works.

@jamesnicolas5323

5 ай бұрын

A couple of other search tips I use often but don't see much in the wild. If you do a search with /, and later want to use the same search in an :s or :g command, you can do :s// or :g// and it will use the / register automatically If you want to append, surround, or prepend a search using the :s command, you can do so with the \0 capture group instead of wrapping with \(\) For example: :%s/foo/\0bar/g will append bar to all instances of foo.

What is the name of the video where you solved this problem?

At this point one wonders why one doesn't simply use variables or registers to solve this.

You actually don't need that crazy regex at the end. Once you have all the lines with 4 characters, you can create another macro to identify duplicates for one line and then apply it to all lines. You go to the first column, copy the current character to register A, then press dt followed by register A. (I'm not quite sure how to do that, but it should be possible. I'm watching this on my phone at 2am). Then press L and repeat the above steps for three times. Apply the macro on all lines. Then delete the first 3 characters from all lines. The first line with an entry will be the one you're looking for. Remember the line number. Undo theb delete operation and jump to that line to see the actual letters

I would do a regex where the first is a capture group of any single character, then the next 3 are capture groups of negative matches of \1 | \2 | \3 etc. probably not great performance to say the least. On mobile so I can't test it but I'll give it a shot later and edit this comment

You actually can do it with regex, but you'd need to use backrefs which (IIRC) Vim's regex engine doesn't support. (And that would just *find* the unique sequence, I don't know if Vim could get you the *location* of it from the match.) Edit: lol d'oh; I guess it does support backrefs

@freyja5800

5 ай бұрын

you can use lookbehinds, combined with lookaheads & backreferences, to find just the last character of a sequence of unique characters though at least with the very simple scheme I used as a short proof of concept, neovim refused to match anything after a certain length, Including wildcards (though that is a limitation of the engine, not of regex in the abstract)

@Yotanido

5 ай бұрын

You're actually not entirely wrong about vim not supporting backrefs. Vim has two regex engines, a fast one, and one with more features. Backrefs are not supported by the fast one, so it has to switch to the slower one. (The fast regex engine can only do actual regular expressions. If the language it is parsing is not regular, it can't do it.)

I think this is regex will directly find the first sequence of 4 characters that are different in *vim*: /\v(.)(%(\1)@!.)(%(\1|\2)@!.)(%(%(\1|\2)|\3)@!.)/ \v -- enable 'very magic' (fewer \s) (x) - capturing group . - match any single character %(x) - non-capturing group x@! - negative lookahead assertion x|y - "or" between two 'atoms', note: I tried %(\1|\2|\3), doesn't work this is pretty straight-forward really but it was annoyingly difficult to get it working due to oddities with vim pattern (mainly that last one) It reads as: find any character, followed by any character that is not the first character, followed by any character that is not the first or second character, followed by any character that is not the first or second or third character

So in VIM regex we escape characters that we want to work like special not other way around ?

@atijohn8135

5 ай бұрын

vim (by default) uses the Basic Regular Expression scheme, where the .*[]^$ characters are treated like special characters without a backslash, and every other special character (e.g. (){}|+?) must be preceded by a backslash. you can make more characters "special by default" by typing \v at the beginning of the regex, or make even the basic characters require a backslash by typing \V at the beginning of the expression

Apparently VIM doesn't even have macro counters 😂 - Emacs user
