Vim: Delete from cursor to next period - vim

Is there a shortcut in vim to delete from the current cursor to the end of the sentence?
cursor
v
This is half a sentence. My cursor is here, but I would
like to delete to this period. I do not want to delete this part.
^
delete from cursor to here
Imagine my cursor is somewhere on the text that says My cursor is here,. How can I delete from this line all the way (and including) that next .?

Though there's no exact motion for that, there are several possibilities:
The ) motion deletes the remainder of the sentence, but that also includes the whitespace after the period.
If there were no hard line break, you could use the useful f motion (which only works in the current line, unless you install a plugin): f. This is also useful if you want to keep the period: t.
The most general motion is search via /. You need to search for a literal period (\.), and to include it, move to the end (/e) of it: /\./e<Enter>.
All of these have to be appended to the d "delete" command, which takes a {motion}.
Learn how to look up commands and navigate the built-in :help (here, :help motion.txt in particular); it is comprehensive and offers many tips. You won't learn Vim as fast as other editors, but if you commit to continuous learning, it'll prove a very powerful and efficient editor.

you should combine d with motion command. for your example, this will be d/\.<Ret>

This visual-mode editing may help you understand what actually happen:
v/\.<Ret>ld

How to delete, including the current character?

Let's say I've typed "abcdefg", with the cursor at the end. I want to delete back to the c, so that I only have "abc" left.
Is there a command like d that includes the current character? I know I could do dTcx, but the x feels like a work-around and I suppose there's a better solution.
No. Backward motions always start on the left of the current character for c, y and d which is somehow logical but also unnerving.
The only "clean" solutions I could think of either imply moving to the char after c first and then do a forward delete:
Tcde
or using visual mode:
vTcd
v3hd
But, given your sample and assuming you are entering normal mode just for that correction, the whole thing sounds extremely wasteful to me.
What about staying in insert mode and simply doing ←←←←?
try this:
TcD
this will leave abc for your example... well if the abcdefg is the last word of the line.
if it is not the last word in that line, you may do:
ldTc
or golfing, do it within 3 key-stroke:
3Xx or l4X
See this answer to a similar question : there is a setting to be allowed to go beyond the end of the line
From the doc :
Virtual editing means that the cursor can be positioned where there is
no actual character. This can be halfway into a tab or beyond the end
of the line. Useful for selecting a rectangle in Visual mode and
editing a table.
"onemore" is not the same, it will only allow moving the cursor just
after the last character of the line. This makes some commands more
consistent. Previously the cursor was always past the end of the line
if the line was empty. But it is far from Vi compatible. It may also
break some plugins or Vim scripts. For example because |l| can move
the cursor after the last character. Use with care!
Using the $ command will move to the last character in the line, not
past it. This may actually move the cursor to the left!
The g$ command will move to the end of the screen line.
It doesn't make sense to combine "all" with "onemore", but you will
not get a warning for it.
In short, you could try :set virtualedit=onemore, and see if your environment is stable or not with it.
Use d?c
That will start d mode, search back to 'c' and then delete up to your cursor position.
Edit: nope, that does not include current position...
I may be misunderstanding your request, but does 3hd$ do it?
I would use vFdd in this example. I think it's nicer than the other solutions since the command explicitly shows what to delete. It includes the current character and the specified character when deleting.
v: enter visual mode (mark text)
F: find/goto character backwards
d: the character "d" that will be included for removal.
d: delete command
Since it is visual mode, the cursor can also be moved before executing the actual removal d. This makes the command powerful even for deleting up to a non unique character by first marking a special character close to the character and then adjusting the position.

Go to first line in a file in vim?

How do I go to first line in a file in vim ?
In command mode (press Esc if you are not sure) you can use:
gg,
:1,
1G,
or 1gg.
Type "gg" in command mode. This brings the cursor to the first line.
Go to first line
:1
or Ctrl + Home
Go to last line
:%
or Ctrl + End
Go to another line (f.i. 27)
:27
[Works On VIM 7.4 (2016) and 8.0 (2018)]
If you are using gvim, you could just hit Ctrl + Home to go the first line. Similarly, Ctrl + End goes to the last line.
Solution
Move to the true starting character of the file, even if it is a whitespace character, by typing only two characters:
go
Go to [count] byte in the buffer. Default [count] is one, start of
the file.
It's arguably even easier to remember than gg (e.g., mnemonic: "Just go to the real beginning of the file, already!"), but perhaps not as comfortable as gg in terms of minimal finger motion (or the ability to use a single finger on one hand to drum this particular "cursor motion beat.")
Unfortunately gg has the "limitation" that it does not go to the true beginning character of the first line when this character and perhaps the characters that follow happen to be whitespaces.
The following other options have the same limitation:
1G
:1<CR>
<Ctrl>-<Home>
Alternatives
Along with gg0, typing <Ctrl>-<Home> <Home> does perform the desired cursor motion to the true first character of the file. It seems somewhat antithetical to ViM principals to use a combination like the latter alternative, but who knows, there may be those that prefer this particular (logical) two key-stroke variation to go, which is why I present it as an potential alternative.
An Aside
Somewhat perplexingly, <Ctrl>-<End> does position the cursor at the true last character of the file, whitespace or not, and is probably the only single (logical) key stroke to do so. Personally, I prefer G$ (or the far more contrived Gg_ to position the cursor at the last non-whitespace character of the file), but if my fingers just happen to be "on the long road home after visiting other relatives in that far away neighborhood of the keyboard and there is a pressing need to stop for gas at the end of the file," well, you just might catch me "breaking the rules" and striking <Ctrl>-<End> to "get the job done."
Limitations
The only pre-requisite for go to work is that ViM is compiled with the byte_offset feature enabled (i.e., +byte_offset). Fortunately, this feature is enabled by default.
To check your particular build of ViM for this feature, you can use the :ve[rsion] command or vim --version from the command line. Both of these display the values of all of the build-time features that were in effect when the instance of ViM being tested was compiled. It is a good idea to commit these all-feature query commands to memory, btw, since the ViM help often refers to feature based restrictions while explaining commands and topics whose availability and/or effect is build feature controlled or restricted.

What are the most-used vim commands/keypresses?

I'm a Ruby programming trying to switch from Textmate to MacVim, and I'm having trouble wading through the gargantuan lists of things you can do in VIM and all of the keypresses for them. I'm tired of hearing "You can use 'I' for inserting text, or 'a' for appending text after the character, or 'A' for appending text at the end of the line, or…" I can't imagine everyone uses all 20 different keypresses to navigate text, 10 or so keys to start adding text, and 18 ways to visually select an inner block. Or do you!?
My ideal cheat sheet would be the 30-40 most-used keypresses or commands that everyone uses for writing code on a daily basis, along with the absolute essential plugins that rubyists use daily and the 10 most-used commands for them. In theory, once I have that and start becoming as proficient in VIM as I am in Textmate, then I can start learning the thousands of other VIM commands that will make me more efficient.
Or, am I learning VIM the wrong way altogether?
Here's a tip sheet I wrote up once, with the commands I actually use regularly:

Vim has some features that make it easy to highlight lines that have been changed from a base version in source control. I have created a small vim script that makes this easy: http://github.com/ghewgill/vim-scmdiff
http://www.viemu.com/a_vi_vim_graphical_cheat_sheet_tutorial.html
This is the greatest thing ever for learning VIM.
Here is a great cheat sheet for vim:
Have you run through Vim's built-in tutorial? If not, drop to the command-line and type vimtutor. It's a great way to learn the initial commands.
Vim has an incredible amount of flexibility and power and, if you're like most vim users, you'll learn a lot of new commands and forget old ones, then relearn them. The built-in help is good and worthy of periodic browsing to learn new stuff.
There are several good FAQs and cheatsheets for vim on the internet. I'd recommend searching for vim + faq and vim + cheatsheet. Cheat-Sheets.org#vim is a good source, as is Vim Tips wiki.
What most people do is start out with the bare basics, like maybe i, yw, yy, and p. You can continue to use arrow keys to move around, selecting text with the mouse, using the menus, etc. Then when something is slowing you down, you look up the faster way to do it, and gradually add more and more commands. You might learn one new command per day for a while, then it will trickle to one per week. You'll feel fairly productive in a month. After a year you will have a pretty solid repertoire, and after 2-3 years you won't even consciously think what your fingers are typing, and it will look weird if you have to spell it out for someone. I learned vi in 1993 and still pick up 2 or 3 new commands a year.
#Greg Hewgill's cheatsheet is very good. I started my switch from TextMate a few months ago. Now I'm as productive as I was with TM and constantly amazed by Vim's power.
Here is how I switched. Maybe it can be useful to you.
Grosso modo, I don't think it's a good idea to do a radical switch. Vim is very different and it's best to go progressively.
And to answer your subquestion, yes, I use all of iaIAoO everyday to enter insert mode. It certainly seems weird at first but you don't really think about it after a while.
Some commands incredibly useful for any programming related tasks:
r and R to replace characters
<C-a> and <C-x>to increase and decrease numbers
cit to change the content of an HTML tag, and its variants (cat, dit, dat, ci(, etc.)
<C-x><C-o> (mapped to ,,) for omnicompletion
visual block selection with <C-v>
and so on…
Once you are accustomed to the Vim way it becomes really hard to not hit o or x all the time when editing text in some other editor or textfield.
I can't imagine everyone uses all 20 different keypresses to navigate text, 10 or so keys to start adding text, and 18 ways to visually select an inner block. Or do you!?
I do.
In theory, once I have that and start becoming as proficient in VIM as I am in Textmate, then I can start learning the thousands of other VIM commands that will make me more efficient.
That's the right way to do it. Start with basic commands and then pick up ones that improve your productivity. I like following this blog for tips on how to improve my productivity with vim.
tuxfiles.org holds a pretty good cheat sheet. I think there are a couple of points to learning the commands:
Read the cheat sheet regularly. Don't worry about using all of them, or remembering all the keys, just know that the command exists. Look up the command and use it when you find yourself doing something repetitive.
If you find yourself doing something regularly (like deleting an entire line after a particular character d$), go a quick google search to see if you can find a command for it.
Write down commands you think you'll find useful and keep that list where you can see it while you're writing your code. I would argue against printing something out and instead encourage you to use post it notes for just a few commands at a time.
If possible, watch other programmers use vim, and ask them what commands they are using as you see them do something interesting.
Besides these tips, there are some basic concepts you should understand.
vim will use the same character to represent the same function. For example, to delete a line after a character use d$. To highlight a line after a particular character use v$. So notice that $ indicates you will be doing something to the end of the line from where your cursor currently is.
u is undo, and ctrl+r is redo.
putting a number in front of a command will execute it repeatedly. 3dd will delete the line your cursor is on and the two lines that follow, similarly 3yy will copy the line your cursor is on and the two lines that follow.
understand how to navigate through the buffers use :ls to list the buffers, and :bn, :bp to cycle through them.
read through the tutorial found in :help This is probably the best way to 'learn the ropes', and the rest of the commands you will learn through usage.
Go to Efficient Editing with vim and learn what you need to get started. Not everything on that page is essential starting off, so cherry pick what you want.
From there, use vim for everything. "hjkl", "y", and "p" will get you a long way, even if it's not the most efficient way. When you come up against a task for which you don't know the magic key to do it efficiently (or at all), and you find yourself doing it more than a few times, go look it up. Little by little it will become second nature.
I found vim daunting many moons ago (back when it didn't have the "m" on the end), but it only took about a week of steady use to get efficient. I still find it the quickest editor in which to get stuff done.
Put this in your .bashrc to open vim with last edited file at last edited line

Is there some pattern behind the many VIM commands?

I have to add a VIM personality to an IDE. I never used VIM for more than the most basic edits and i'm now overwhelmed by the complexity of the command structure.
Is there any overall structure for the combination of counts moves and insert/delete commands?
I just can't see the wood for the trees.
Well, there is obviously a finger position pattern behind h, j, k, l.
The fact that ^ goes to the beginning of a line and $ goes to the end is patterned on common regular expression syntax.
Ctrl-F and Ctrl-B page forward and back, and that's fairly intuitive.
i inserts (before) and a appends (after the cursor). Similarly,
I inserts at the beginning of the line, and A appends at the very end.
> and < indent and outdent, respectively. That's also kind of intuitive.
But on the whole, many of the other commands are on whatever keys were left – it's hard to find an intuitive mapping between the letters of the alphabet and an editor's commands.
Repeat counts are always entered before a command, and mostly repeat the command that many times, but in some cases do something clever but analogous.
I think the secret to not going crazy over vi is to start out with only a small handful of commands. I have a lot of colleagues who don't know to do anything other than
move the cursor around using the arrow keys (you don't have to use h, j, k, l);
insert with i, delete with Del (you don't have to use x);
delete a line with dd
get out of input mode with Esc
get out of vi with :x (exit) or q! (quit, and throw away my changes!)
Because I'm much smarter, the additional commands I know and use are:
go to the top of the file with gg, the bottom with G.
I can go to a specified line number with (line-number)G.
copy a line with y (yank), paste it with p
change a word with cw, the rest of the line with C
delete a word with dw, the rest of the line with D
I sometimes use . to repeat the last command, or u (undo) if I messed up.
When you have occasion to use other commands, you can teach them to yourself one by one as needed.
This is a good article for explaining the VIM philosophy.
I think the characteristic that better defines VIM in respect to other editors is its wide array of motion commands. The first thing to learn to fully use VIM is hitting the arrow keys as little as possible, and think at the text in terms of "blocks" like "a sentence" "a tag" "a word" "a group of brackets".
Say you have function foo($bar, $fooz) you can change the parameters by simply positioning your cursor anywhere inside the brackets and pressing ci) (mnemonic: change inner bracket). The same pattern applies to other commands: yank (y), delete (d) and so on.
I know this doesn't explain the whole "VIM philosophy" but combining normal mode commands with the vast amount of motion modifiers is what really made me see the light.
There are plenty of nice and interesting tutorials. One example is
http://blog.interlinked.org/tutorials/vim_tutorial.html
But the broad structure that most of them would give you is
There are two main modes for editing - Command mode and insert mode. You can move from insert mode to command mode using the key.
You can execute commands in the command mode by typing a single key or a sequence of keys.
Commands can help you achieve a wide variety of things
deletion of lines - dd
yanking (copying of lines ) - yy
pasting lines below the current line - p
pasting lines above the current line - P ( and so on)
Most commands in the command mode can be pre-fixed by a "count" to indicate the number of times the command has to be executed. For example, 3dd would delete three lines.
One set of commands in the command mode lets you move to the insert mode. That is explained below.
There are different ways of entering the insert mode from the command mode. Prominent among them are (i-insert at cursor, I-insert at beginning of line, o-insert a line below, O-insert a line above, a-append, A-append at end of line.
The quick reference at
http://www.andy-roberts.net/misc/vim/vim.pdf
Will help you understand the relevance of "count"

In vim, how do I go back to where I was before a search?

Programming in vim I often go search for something, yank it, then go back to where I was, insert it, modify it.
The problem is that after I search and find, I need to MANUALLY find my way back to where I was.
Is there an automatic way to go back to where I was when I initiated my last search?
Ctrl+O takes me to the previous location. Don't know about location before the search.
Edit: Also, `. will take you to the last change you made.
Use `` to jump back to the exact position you were in before you searched/jumped, or '' to jump back to the start of the line you were on before you searched/jumped.
I've always done by it setting a mark.
In command-mode, press m[letter]. For example, ma sets a mark at the current line using a as the mark identifier.
To get back to the mark press ' [letter]. For example, 'a takes you back to the line mark set in step 1. To get back to the column position of the row where you marked the line, use `a (back-tick [letter]).
To see all of the marks that currently set, type :marks.
On a slightly unrelated note, I just discovered another nifty thing about marks.
Let's say you jump to mark b by doing mb. Vim automatically sets the mark ' (that's a single-quote) to be whichever line you were on before jumping to mark b.
That means you can do 'b to jump to that mark, then do '' (2 single-quotes) to jump back to wherever you were before.
I discovered this accidentally using the :marks command, which shows a list of all marks.
You really should read :help jumplist it explains all of this very well.
CTRL+O and CTRL+I, for jumping back and forward.
I use this one:
nnoremap / ms/
nnoremap ? ms?
Then if I search something by using / or ?, I can go back quickly by `s. You could replace the letter s to any letter you like.
The simplest way is to set a mark, with m[letter], then go back to it with '[letter]
