Continuing a macro across buffers in vim - vim

I've got a large config file that i'm in the process of splitting out into individual ones based on section.
My workflow is like this:
Visual select the block of text in the main file (v)
Cut the text into the kill buffer (d)
Open a new buffer (:sp newfile.pp)
Paste the text (p)
Save the file with a new name and close the buffer (:wq! somefile.pp)
I tried creating a macro to do this, basically taking the steps above, but add (q a) right before cutting the text, and q again right after pasting. My macro stops as soon as the new buffer is open and won't run the paste command. I have to do this by hand.
Ideally: those steps above would complete to the point where I'd be left with the :wq! entered into the command line just waiting for me to give a filename and hit enter to close and save the buffer.
Is this possible, and how would I accomplish it without writing a script?
Edit
Found another faster way to do the same thing:
Visual select the text
Start typing a (:) command.. vim helpfully prefixes the command line to indicate an operation on your selection
:w filename.pp
Delete the block with (g v d)
Still curious why my recorded macro stops when a new buffer is created, though.

I had the same issue as you. I found out that the q after the p was not stopping the macro recording. I hope this is what you were seeing. To populate register a with content you can run (the ^# is entered by ctrl-v, ctrl-j):
let #a="d:sp! newfile.pp^#p"

How to repeat a navigation command in Vim

The . key can be used to repeat the last insert command. However, we might do some navigation that is not part of the insert, but we want it repeated.
Imagine commenting out lines like so:
// line of text
// line of text
line of text
line of text
The insert command is to put the two forward slashes and a space. That can be repeated using the . key. The navigation would be to navigate down one line and then left some number of characters. That part is not captured by the . key command.
How can we achieve this functionality? I read that it was not available in Vi some years ago, but I'm wondering if it exists now in the latest version of Vim.
Press qX, where X is any of the writable registers (typically: pick any lowercase letter).
Do whatever actions you want to record.
Press q again to stop recording.
Press #X (where X is the same register) to play it back (count times, if used with a count).
Press ## to replay the most recently used macro (count times).
I read that it was not available in Vi some years ago, but I'm wondering if it exists now in the latest version of Vim.
If the Vim docs are to be believed, Vi did not support recording (steps 1-3), but did support #. Then you would have to manually yank the characters into the target register with "Xy<motion> or some other register-writing command. That also works under Vim, but I can't recommend it because it is much more error prone.
Another approach would be "block select then edit" approach:
ctrl + v - block select
then go down j or down-arrow
shift + i will put you in insert mode. Make the change here where you want it to be reflected on all the other lines you've selected.
esc twice will show/repeat that change you made on the line one.
If you have a big range of similar lines and want to put // at the beginning of it, you can do something like:
:15,25norm! I//<space>
You can also use visual area (vip selects an entire paragraph)
:'<,'>norm! I//<space>
using a pattern
:g/TODO/norm! I//<space>

less viewer: Copy all the lines to clipboard

There has already been a post in stackoverflow for VI editor for copying all the text into the clipboard. (Copy all the lines to clipboard) I want to do the same thing with the less viewer. I tried to search online for the process called "yank" and I did not find anything for it.
How do I copy all lines in the less editor into the clip board.
And I cannot close less and reopen it in vi. It is because of the fact that I have managed to load this file into the editor and while I have loaded it, the file has already been moved in the back end. It is a long story. The easiest solution for me now is to copy the contents of the file into memory.
less doesn't have a clipboard, but you may be able to get it to output what's stored in its buffers to a new file. This will only work if the entire contents of the file are buffered:
Type g to go to the top of the file
Type | (that's a pipe character, not an L or I) to indicate that you want to output to a pipe
Type $ to indicate that you want the output content to go to the end of the file
Type dd of=/path/to/new/file and press Enter
The dd command will take the piped data and save it to the file passed to the of= argument.
as an workaround you can set terminal's font size to 1, then select with mouse and copy (works for big , but not huge files).
If the file is not too big and if it fits in your terminal number of lines configured, then do the following:
Terminal > Edit > Clear to start
cat <file_name>
Terminal > Edit > Select all
Terminal > Edit > Copy

What does ccw do in Vim macro

In the following vim macro from this article, the author gives an explanation. I understand some but not everything.
:qccwcommand<Esc>:w<Ctl-W>jj<Enter>q
This macro (which includes the record start / stop, if you’re wondering) will change the current ‘path_to_command’ word to ‘command’, write the file out to disk, change window splits to the grep search results, move down one line in the results and navigate to that result’s location.
Q1. What is ccw doing here? Is it something to do with cw (change word) but I am not sure.
Q2. :w must be to write, right?.
Q3. What is <Ctrl-W>jj doing here? The following is what :h CTRL-W_J is about but I am not sure if I am looking into the correct help nor the meaning of the help in this context.
*CTRL-W_J*
CTRL-W J Move the current window to be at the very bottom, using the
full width of the screen. This works like closing the current
window and then creating another one with ":botright split",
except that the current window contents is used for the new
window.
you're confused because ccw taken literally in that sequence of commands dosen't really make sense!
the initial qc means "start macro recording in register c"
then the next cw means change word (e.g. delete the next word and leave editor in insert mode)
also notice that the final command is a q: this means to finish the macro recording. Macros are super useful when doing things that require a lot of repetition!!1 --> http://vim.wikia.com/wiki/Macros
then, his explanation in the blog post contains the answer to Q2 and Q3
This macro (which includes the record start / stop, if you’re wondering)
will change the current ‘path_to_command’ word to ‘command’, write the file
out to disk, change window splits to the grep search results, move down one
line in the results and navigate to that result’s location. I ran the macro
by hitting #c and then verifying the line selected was one that I wanted to
change. For a few instances where I did not want to change the line, I
manually navigated to the next search result and then re-ran the #c macro.
Q2 - yup, to save the file: "write the file out to disk"
Q3 - the <Ctl-W>jj<Enter> is a sequence of Vim key commands to move to the next entry in the quickfix window from the vimgrep, as he indicates: "write the file
out to disk, change window splits to the grep search results, move down one
line in the results and navigate to that result’s location."

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:
References
vim documentation online
advanced vim tips
more useful tips and graphical cheat sheet
General
Nearly all commands can be preceded by a number for a repeat count. eg. 5dd delete 5 lines
<Esc> gets you out of any mode and back to command mode
Commands preceded by : are executed on the command line at the bottom of the screen
:help help with any command

By line:
0 start of line; ^ first non-whitespace
$ end of line
By paragraph:
{ previous blank line; } next blank line
By file:
gg start of file; G end of file
123G go to specific line number

^N (in insert mode) automatic word completion
Show local changes
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.

Vim: insert text from a file at current cursor position

To insert text from a file in the current Vim buffer I use :r filename to insert the text below the cursor or :0r filename to insert in the first line.
How do you insert the contents of a file where [Cursor] is located?
Actual line with some coding [Cursor] // TODO for later version
Line below actual line ...
This inserts the contents of the file whose path is at the cursor position:
:r <cfile>
Insert a line break, read the file, and then take out the line break...
I propose Ctrl-R Ctrl-O = join(readfile('filename','b'), "\n")
Other solution:
Possibly open the other file in another window, use :%yh (h is a register name) and in your original file, in normal mode use "hp or "hP or in insert mode, Ctrl-R Ctrl-O h
To expand on the accepted answer with actual code, since I tried the suggestion and it worked nicely;
Here is an example of it working to insert a little php snippet:
`nnoremap <leader>php a<CR><ESC>:.-1read $SNIPPETS/php<CR>I<BS><ESC>j0i<BS><ESC>l`
In general the syntax is
`nnoremap [KEY SEQUENCE] a<CR><ESC>:.-1read [FILE PATH]<CR>I<BS><ESC>j0i<BS><ESC>l`
Just to break it down:
nnoremap : I'm about to define a new key mapping for normal mode
<leader>php : I would like to trigger the command sequence when this key combination is pressed. In my case <leader> is , so I type ,php to trigger the command.
Now for the command, bit by bit:
a<CR><ESC> : go into insert mode (after the cursor), insert a line break, go back into normal mode.
:.-1read <file><CR> : this enters the desired file on the line above the current line.
I<BS><ESC> : jump to the start of the line, delete line break, return to normal mode.
j0i<BS><ESC>l : Go down one line (to the remainder of the line that you were initially on), jump to the start, enter insert mode, delete the line break, return to normal mode.
l : position the cursor to the right of the pasted file (this just made the command work more like how you expect it to).
note
You have a choice of whether to paste before or after the cursor. I have chosen in this example to paste after the cursor because that is how the p command usually works to paste yanked text. Alternately, to paste before the cursor you should change the a at the start of the command to an i. You could use one of these exclusively, or you could bind them both to different but related key sequences. For example:
`nnoremap <leader>php i<CR><ESC>:.-1read $SNIPPETS/php<CR>I<BS><ESC>j0i<BS><ESC>l`
Could paste text before the cursor,
and :
`nnoremap <leader><leader>php a<CR><ESC>:.-1read $SNIPPETS/php<CR>I<BS><ESC>j0i<BS><ESC>l`
could paste text after the cursor. Or vice versa. I have made 'before the cursor' easier to trigger because I use it more often when pasting in-line.
other note
This solution is mainly useful if you're reading from a file that you expect to use often enough that it's worthwhile setting up a key mapping for it (ie reading a snippet from a file). This doesn't really help if you just want to read in a random files whenever since you won't have the key mapping ready.
Since it is very formulaic, I'm sure it would be possible to define a function that would take the file name as an argument and do the same thing though. I've never written a function in vimscript though so if someone who knows more feels like editing this answer to contain that solution - I urge them to do so!
