I know that I can get into bash while in vim via:
Ctrlz
or
:sh
or
:shell
etc.
Then use bash commands as normal, and get back out using fg.
What I am wondering is, can I execute a line of code from a script in vim straight to Bash, without having to exit vim, or having to copy it (via highlighting in visual mode for example) from vim, then going to a terminal and pasting it and hitting enter etc.?
Easiest way is to put the cursor on the line and type:
!!shreturn
This will replace the line with the output of the script. If you don't want that, simply follow up with u.
Arguably easiest way:
Yank the text you want to execute.
Open the cmdline (by pressing :)
type ! and then press ctrl-r and ", which will paste the content of the unnamed register to the cmdline (which will contain the text you wanted to execute)
press Enter

Sometimes when you ctrl-v with bash it will run the command even though you didn't intend to run it yet - is there a way to paste a command into the bash shell / terminal making sure you don't actually run any of the command(s)?
if you could set what was on the terminal prompt programmatically, you could do this with bash on MacOS:
export BASH_PROMPT="$(pbpaste)"
which ties into my other question that I just asked:
How to change the value that's in the prompt
There is a Readline variable:
enable-bracketed-paste
When set to On, Readline will configure the terminal in a way that will enable it to insert each paste into the editing buffer as a single string of characters, instead of treating each character as if it had been read from the keyboard. This can prevent pasted characters from being interpreted as editing commands. The default is off.
To turn this on, put something like
set enable-bracketed-paste on
into your ~/.inputrc.
This was introduced in Bash 4.4 / Readline 7.0.
Use ^X^E aka Ctrl+X Ctrl+E in bash to open your $EDITOR for command entry.
Paste and/or edit as much as you want, across as many lines as you want. When you're done, save and exit, and bash will run it.
(In vi mode, the shortcut is v)
Is there a way to highlight my input into the bash console while typing code?
For example, if I use bash keywords, those are highlighted in a specific color?
edit:
I'm particularly interested in solutions which make use of what bash already has to offer, like tweaking .bash_profile or similar.
You can use the syntax highlighting feature of vim/vi.
Open a file, for example open existing file called file.sh, enter
vi file.sh
Now press ESC key, type “: syntax on” i.e. type as follows
:syntax on
To turn it back off, press ESC key, type : syntax off
:syntax off
To make it permanent you can create a new .vimrc file in your home directory. Open the terminal and enter:
vim ~/.vimrc
There you can enter your various configurations. When done, you need to save the file and restart vim.
To be sure which vimrc is being used, you can ask inside of vim by typing:
:echo $MYVIMRC
Hey is there a way or plugin to execute Code e.g. Ruby in my case, directly from my vim editor. I know this from Textmate, where you can execute Code with Cmd+R or Cmd+B in Sublime Text2. In Sublime Text it is called Build System.
Thanks for advise!
If you just want to execute the current buffer in Ruby, you could do this in normal mode:
:!ruby %
You could also map that to a shortcut with your leader key:
:map <leader>r :!ruby %<cr>
Which would let you do leader+r to run the file.
My vim has a :rubydo command, select the section of code you want to execute (or nothing to execute the whole buffer), and do
:rubydo
"'<,'>" will be added automatically after ":" if something was selected.
that should to the trick
Well, one simple thing you can use is to execute a command in your shell with :!.
# Typing typing typing...
# Oh! Gotta commit.
:!hg ci -m "Add awesome module xyz"
Or you can use :shell to drop into the shell, if you're going to be doing more complex things.
Use the :!<anything want bash or the calling shell of vim to execute>. So if you have a script named foo.rb, to execute it from within the vim editor call :!ruby foo.rb.
ruby-runner is a vim plugin that allows you to run ruby script from within vim, the good part is you can see your code output along with the your code at the same time.

IMHO the better option is to use rcodetools.
Often I find my self navigating the filesystem from a Conque shell in Vim and want to open a specific file inside my existing MacVim session. Is this possible ? - I was hoping for something like:
shell> open some/file.txt
and then have file.txt pop up inside my existing Vim window (preferably in a new tab).
Note: I am using #wycats vim dot files (not sure this matters).
Type from ConqueShell
mvim --remote-tab-silent filename
This will open the file in a new tab in MacVim
You could also write a Bash alias to shorten the command (assuming you are using bash).
Put in your ~/.profile
alias vim='mvim --remote-tab-silent'
this would enable you to type
vim filename
from ConqueShell or bash, and have it open in a new MacVim tab, rather than terminal vim. It of course does disable your ability to run standard vim (although you could still use the vi command), so maybe you would want to name the alias differently.
Just to add, this will work only if you placed the mvim executable on your path E.G. /usr/bin/mvim. It comes with the MacVim.app

The beauty of running a shell from inside vim is you have all of vim and the shell at your disposal.
gf is your friend. Once you get the file you want displayed on the screen in some way, you can enter normal mode, move the cursor to the file you want to edit, then use the gf command to navigate to the file. There are many ways to use this. Any program or command that outputs file names is great for this (ll, git status, etc). You could also type the filename into the shell, just to make it visible on the screen without actually running any terminal commands (tab completion is handy here).
It is possible, you can start vim as server and then add as many files as you want, but I'm not very familiar with this, so I can't give you just a direction.
I found an awesome tip here. You can "[r]apidly invoke an editor to write a long, complex, or tricky command". However, when I press the key combination above, I get Emacs open. I would like to switch it to Vim. How can I invoke Vim with C-X e?
[1. Problem SOLVED by Brian Cambell]
export EDITOR=vim
Add to your .bashrc or appropriate shell rc file

I was unable to get the tricky command back to Bash. The errors were:
> Error detected while processing BufRead Auto commands for "*":
> E117: Unknown function: JumpToLastPosition
Quotes in .vimrc solved the second problem. I am still unsure about the part in my .vimrc:
" augroup misc
" autocmd!
" autocmd BufReadPost * call JumpToLastPosition()
" autocmd FileChangedShell * call WarningMsg("File changed outside of vim")
" augroup end
[3. Problem]
What do the above part in .vimrc do?
On most Linux installs (all the ones I tested), bash recognizes both the Emacs and Vi command history keys (or you can use "set -o vi" to force it).
So, you can just use the vi-mode "<ESC>v" to to enter visual mode, this will start editing in a Vim session.
To run the command, you just save and exit from Vim ("ZZ" or ":wq"). To cancel the command, you need to delete the contents, save and exit ("1GdGZZ").
In addition to running it by exiting, you can also save it while in the editor to another location (":w /tmp/myscript").
Keep in mind that visual mode will work with the currently selected line so you don't have to start with a blank command ("<ESC>v"). You can use the normal vi-mode tools to select a line from the history first and then enter visual mode ("<ESC>kv" for last command, "<ESC>/grep<ENTER>nnv" for third-last grep command and so on).
Using this method has the advantage of not changing the "EDITOR" variable which may be used for other things (unless you want Vim for everything, which is a very sensible position to take IMNSHO).
Update:
Regarding your error, posted after the question:
JumpToLastPosition() is the function called by Vim for all files to put the cursor where it was when you last edited the file. I'm going to assume you're actually getting this error when the editing starts, not when you exit, since this is the auto function following a buffer read.
Can you start a "normal" vim session ("vim xx.txt" and then "vim xx") without this error occurring? You may find you get the same problem (and possibly only on the last one).
If you do have the same problem, you need to look at your startup files. It's possible the autocmd for BufRead is broken somehow. Have a look inside your vimrc and you filetype.vim files to see where that function is called and/or defined (I suspect it's called but not defined and that may be a mismatch between the two files or one of them has been damaged).

The link that you provided contains the answer:
Next time you are using your shell, try typing ctrl-x e (that is holding control key press x and then e). The shell will take what you've written on the command line thus far and paste it into the editor specified by $EDITOR.
You need to set the EDITOR environment variable (like #Brian Campbell)
