I am looking to rebind the ^ shortcut in normal mode (goes to the first non-whitespace character of the line), to use q instead. However, I can't seem to find the name of the command that is appropriated for this : I have tried "commands": ['cursorLineStart'] but this goes to the beginning of the line, including whitespace characters, which is not what I want.
Does anyone know the exact name of the command associated with ^ ?
Not exactly what you are asking but would this suffice:
nnoremap q ^
Edit:
Adding an operator pending motion so OP can do things like dq as mentioned in the comments.
onoremap q ^

I am trying to use relative line numbers with NeoVim to jump through my file so I am expecting to digit to jump 20 lines before:
:20k
and to jump 20 lines after:
:20j
I tried but nothing happens.
So I tried to add this configuration to my init.v file:
nnoremap <expr> j v:count ? 'j' : 'gj'
nnoremap <expr> k v:count ? 'k' : 'gk'
But when I insert something like: :20j it gives me this error:
E471: Argument required
How can I achieve my goal?
You can achieve your goal by learning properly how to use your tools. I don't know if Neovim still has it but Vim comes with $ vimtutor for the basics and you can still probably follow :help user-manual.
Case in point, it is 20j, not :20j.
^ stands for start of a line in Vim. But what if I does want to search for the character ^ itself but not start of lines? I have tried \^ but it seemed not work.
In you vim session type /\^. It works see :)
I just started with vim script and try make translation of opencart language files easier. I want to have a function that looks for a given search pattern and selects it. If there is no match left in the file, it shall open the next file for editing. What I have so far:
function! Nextmatch()
normal /\(= *'\)\#<=.\{-\}\('\)\#=/
normal v//e
endfunction
function! Nextfile()
if !exists("s:filecounter")
execute "!find -iname *.php > files.txt"
normal <CR>
let s:filecounter=0
endif
let s:lines= system("wc -l < files.txt")
if s:filecounter<s:lines
w
let s:filecounter += 1
let s:sedcommand="sed '".s:filecounter."!d' files.txt"
let s:selectedfile=system(s:sedcommand)
execute 'edit' s:selectedfile
else
wq
endif
endfunction
How can I achieve that Nextfile() is called in Nextmatch() if the search pattern is not found between the cursor and the end of the current file? And is there something that you consider to be bad style in my snippet?
Quickfix commands are powerful and well integrated with some external plugins, but if you really need to use your own script, and if you need to check a match in an if statement, just do:
if search("=\\s*'\\zs[^']*\\ze", 'W') == 0
echo 'No match until the end of the buffer'
endif
See :h search(), and please note :
the double backslashes, due to the double quotes
the 'W' flag which forbids wrapping around the end of file
I simplified the pattern you gave
You could simply use the :vim command to get rid of all your script.
I think the following should do quite what you're expecting:
:noremap <f8> <esc>:cn<cr>gn
/\(= *'\)\#<=.\{-\}\('\)\#=
:vim //g *.php
Then, to go to the next pattern in all files while selecting it,
you just have to press the F8 key.
In the noremap line, gn let you select the next actual search.
You may need to do:
:set nohidden
to let you navigate threw modified buffers (but don't forget to save
them with :wa, or list them with :ls)
About your script:
It's a good habit in scripts to always use :normal! instead of :normal (unless you deliberately need it) : thus, your personnal mappings won't interfer in your scripts.
How do I map a substitution to a key in my .vimrc without getting an error when I source it?
I'm trying to add
nnoremap <leader>re :'<,'>s/<%=*\s//g | '<,'>s/\s-*%>//g
to my .vimrc but when I do so and reload the file I get the following error:
The problem is that you're combining two :s commands, but the command separator | concludes the :map command, so that the second substitution is executed immediately, causing the error. You need to escape the |, or better use the special <Bar> notation inside mappings:
nnoremap <leader>re :'<,'>s/<%=*\s//g <Bar> '<,'>s/\s-*%>//g
PS: Wouldn't it be more natural to define the mapping in visual mode (as it works on the last selection, anyway)? With a :vmap, the first '<,'> range will be inserted automatically:
xnoremap <leader>re :s/<%=*\s//g <Bar> '<,'>s/\s-*%>//g
I've written a few macros in my .vimrc for the version control system I'm using (Perforce) (please don't suggest the perforce plugin for vim, I tried it and I don't like it). They all work fine except the revert macro, which breaks due to a confirmation prompt (which I need so I don't accidentally fat-finger my changes away). It currently looks like this:
map <F8> :if confirm('Revert to original?', "&Yes\n&No", 1)==1 | !p4 revert <C-R>=expand("%:p")<CR><CR><CR>:edit<CR> | endif
This causes bash to complain when vim tries to load the file:
bin/bash: -c: line 0: syntax error near unexpected token `('
Looking at the buffer bash sees, it looks like the error is that vim sends it everything after the first pipe, not just the part meant for bash. I tried a few alternatives but I can't seem to make it work. I've got it to show confirm dialog correctly when I removed the pipes and endif (using shorthand if), but then vim complains after the user gives a response.
I think you want something along these lines:
:map <F8> :if confirm('Revert to original?', "&Yes\n&No", 1)==1 <Bar> exe "!p4 revert" . expand("%:p") <Bar> edit <Bar> endif<CR><CR>
Remember that :map is a dumb sequence of keystrokes: what you're mapping F8 to has to be a sequence of keystrokes that would work if typed. A <CR> in the middle of the :if statement doesn't mean ‘and press Enter when executing the command at this point if the condition is true’; it means ‘press Enter here when in the middle of typing in the :if command’, which obviously isn't what you want.
Building it up a piece at time, from the inside out:
There's a shell command you sometimes want to run.
That shell command needs to be inside an :if to do the ‘sometimes’ bit, and so have an :endif following it.
After a literal ! everything following is passed to the shell, including | characters which normally signify the start of another Vim command. That's reasonable, because | is a perfectly good character to use in shell commands. So we need some way of containing the shell command. :exe can do this; it executes the supplied string as a command — and its argument, being a string, has a defined end. So the general form is :if condition | exe "!shell command" | endif.
Your shell command has an expression in it. Using :exe makes this easy, since you can simply concatenate the string constant parts of the command with the result of the expression. So the command becomes :exe "!p4 revert" . expand("%:p") — try that out on its own on a file, and check it does what you want before going any further.
Putting that inside the condition gives you :if confirm('Revert to original?', "&Yes\n&No", 1)==1 | exe "!p4 revert" . expand("%:p") | edit | endif — again try that out before defining the mapping.
Once you have that working, define the mapping. A literal | does end a mapping and signify the start of the next Vim command. In your original the mapping definition only went to the end of the condition (check it with :map <F8> after loading a file) and the !p4 part was being run immediately, on the Vim file that defines the mapping! You need to change each | in your command into <Bar>, similarly to how each press of Enter in your command needs writing as <CR>. That gives you the mapping above. Try it by typing it at the command line first, then do :map <F8> again to check it's what you think it is. And only then try pressing F8.
If that works, put the mapping in your .vimrc.
Use of the pipe to string multiple vim commands together is not particularly well-defined, and there are numerous eccentricities. Critically, (see :help :bar) it can't be used after a command like the shell command :! which sees a | character as its argument.
You might find it easier to use the system() function.
E.G.
:echo system("p4 revert " . shellescape(expand("%:p")))
The shellescape() wrapper is useful in case you have characters like spaces or quotes in the filename (or have cleverly named it ; rm -rf ~ (Don't try this at home!)).
In the interest of creating more readable/maintainable code, you may want to move your code into a function:
function Revert()
if confirm('Revert to original?', "&Yes\n&No", 1)==1
return system("p4 revert " . shellescape(expand("%:p")))
endif
endfunction
which you would access by using the :call or :echo command in your macro.
