While programming I am regulary using the following two lines:
sprintf(buff,"%s", __func__);
putrsUART(buff);
Is it possible to set any keyboard shortcut to insert these two lines?
E.g. when I type \sp in command mode, these functions get added at the cursor position in my file. Is this possible? And if so, how do I map my keys?
Thanks in Advance.
You can use abbreviations, which are designed for this.
:abbr spb sprintf(buff,"%s", __func__);
:abbr uart putrsUART(buff);
Use :help abbr for the gory details. Note that you need to type another character after the abbreviated form for vim to recognize them. This comes naturally for these as you will type ENTER as the next character. It is also possible to enter more than one line with abbreviations. Simply use <CR> where you want a new line.
Here's an easy mapping for normal mode that lets you hit \sp (unless you've remapped leader, in which case use that instead of \) in order to insert the sprintf statement.
map <Leader>sp isprintf(buff,"%s", __func__);<Esc>
That being said I think abbreviations are the way to go here
As already mentioned, abbreviations (which I would limit to insert mode (:iabbr), because you probably won't need them in the command-line) are best for simple expansions; you can also define them only for certain filetypes only (via :iabbr <buffer> ...).
Your __func__ looks like a template parameter that you need to adapt each time. You cannot do this via abbreviations, but there are various plugins (many inspired from functionality in the TextMate editor) that offer template insertion with parameter expansion and several advanced features. Check out one of snipMate, xptemplate, or UltiSnips.
Try snip-Mate for inserting regularly used codesnippets. http://www.vim.org/scripts/script.php?script_id=2540
Wrong answer, Sorry:
Try this in your vimrc:
map <c-w> :sprintf(buff,"%s",func)<cr>
This means mapping to Ctrl-W.

I am using JetBrains' phpstorm with the IdeaVim plugin.
I am wondering if I can bind keys in normal mode to editor actions.
For example, I used to have mapped Ctrl+B to Navigate > Declaration. Yet Ctrl+B is a vi motion to go one page backwards and that is ok.
I know I can configure a keyboard shortcut to a different one, e.g. Ctrl+Shift+B , yet to keep things simpler I want to have a key in ideavim's command mode mapped to that functionality, e.g. ;.
So that pressing ; in command mode would trigger the action of Declaration witin phpstorm.
How can I achieve this?
To give a specific answer for exactly what you asked to map: put this into your ~/.ideavimrc:
nnoremap ; :action VimGotoDeclaration<CR>
To find the action name, I typed :actionlist declaration which gives a subset of action names that include the word "declaration" in the action name.
As others have noted, you might also prefer to use one of the existing mappings rather than adding a new one.
what you wanted go to declaration is built in command in vim. You don't have to use IDEA's actions.
gd (goto declaration) is the thing you are looking for.
So you just press (normal mode) gd, to see what is gonna happen.
In a normal vim, do :h gd to check details.
You can use <C-]> (Ctrl+]) for following references (jumping to the declaration is an example of a reference) and <C-O> for going back. You can also map these Vim-style shortcuts using the map commands similar to the original Vim.
I really like the supertab plugin. Reaching <C-x><C-p> is a bit too long and mapping it to tab gives me a better workflow. However, sometime I just want to insert a regular tab and for this I need to insert a space first, i.e. foo<Space><Tab>bar.
This pollute my sources with useless spaces before each tab char (this assuming I don't use expandtab).
I am wondering is there is a smarter way to use auto-completion ?
Going back to <C-x><C-p> which is much slower
Using another key mapping like
Using supertab with a wiser feature:
i. Automatically insert a <Tab> if I press a char that doesn't match any of the possible completions.
ii. Inserting a real tab with
???
Any ideas?
You can suppress the Supertab trigger and insert a literal tab by pressing <C-v><Tab>. (On Windows, that frequently is <C-q><Tab>.)
Supertab also provides a mapping for direct input, by default <C-Tab>; see :help supertab-mappingtabliteral. That default key combination probably only works in GVIM, though.
Just another try.
You can have a global substitute after editing work like:
:%s/ \t /\t/g
Is there any way to define and use snippets on the vim command-line? For example, when I want to select a portion of text I want to replace a string of text within, excluding the rest of the line, I have to change:
:'<,'>
to
:%s\%VsPat/rPat/g
which once in awhile might be alright, but lately I find myself performing this kind of s/S/R/ often enough to make it a PITA; yet still more efficient than making each change in the selection manually.
Actually there are quite a few regular editing command I use in VIM that would increase my efficiency if I could tie them to a snippet somehow. So is there any way to use snippets at vim command-line?
What about just going on with your substitution without changing anything?
:'<,'>s/\%VsPat/rPat/g
Or using a visual mode mapping?
xnoremap <key> :s/\%V/g<left><left>
There is build-in feature cnoreabbrev it is simple replacement, so if you define it for example
:cnoreabbrev ss %s\%VsPat/rPat/g
then when you type :ss and press <space>, it will automatically replace ss with following
:%s\%VsPat/rPat/g
Check it out, it should solve at least half of your problems :-)
I'm swapping some mappings on my keyboard to make it easier on my wrist, but I wouldn't want others to be surprised if they open vim on a computer I had been working on.
So I put these mappings inside a function in my .vimrc so I can selectively enable the mappings.
My question is, how can I tell vim (in the .vimrc file) to call a function if I :set a variable?
Something like :set wrist and it would call SwapKeysForWrist.
Note: I know I can give the function a simpler name and call it, for example :call Shahbaz(), but that requires me to use shift three times (besides :) which is what I'm trying to avoid. In fact, the function swaps the digits with their alternative keys (since I use those symbols much more often than actual numbers during programming), and typing parentheses (added that I'd be holding shift) does strain my wrist.
You cannot define your own :set names, you can only use mappings or custom commands.
I would suggest using a custom :Wrist command; it's short to type and should be easy for you to remember. If you want to get around the uppercase W, you need to use a :cabbrev or the cmdalias plugin.
In my .vimrc I have mapped the #-key to a macro for commenting out/in lines of code.
Unfortunately # in vim already has a function - it searches backwards for the word beneath the cursor.
What I would now like to have is a way to map this functionality to another key-sequence (ideally I would like to have Control-* for that as * alone searches forward).
Does anyone know how to achieve this?
Many thanks!
Unfortunately, Ctrl + * cannot be used; I would propose \*; it's longer to type, but backwards searches are probably not that common.
:nnoremap <Leader>* #
Like Ingo Karkat said, mapping Ctrl+certain keys is impossible in vim. However, you can map Alt+8 instead:
noremap <A-8> #
I suggest Alt+8 instead of Alt+* because if you wanted to bend your hand in unnatural ways to press more than one modifier keys to perform a command, you would probably be using Emacs instead of Vim.
I use \+c for commenting and \+d for removing comments. The mappings are following :
:map \c <ESC>:s,^\(\s*\)[^/ \t]\#=,\1// <ESC>,e<CR>j$a
:map \d <ESC>:s,^\(\s*\)// \s\#!,\1<ESC>,e<CR>j$a
Above mappings are used in command mode. Taken from one answer on SO, which I am currently unable to find.
