Why vim

See this video on why Nir prefers vim to IDE's

• more efficient in what you can do from the keyboard
• autocomplete can use a language server
• scrolling to line: % takes you to end of function;
• 0,^,$ to go to start, first char, end of line;
• / and ?: search
• 'f' and 'F': find in line

This vim doesn't need tabs video You can use splits. (I use both tabs and splits.)

• Close a window with C-w q to close the window but not the buffer whereas :q closes window and closes the buffer if it is the last window with that buffer.
• :bufdo g/function/d does this command on all open buffers

From here. How to delete without copying:

• :reg shows registers
• vim copies to default reg automatically when deleting
• There is a black hole register: "_d to delete without copying
• named registers: "ay, or "qd.

Opening files

Basic Stuff

Regex Search Replace

1. Append to line: :s/$/hello; prepend to line: :s/^/hello;
2. Prepend to first non-whitespace without lookbehind: s/\(\S\)/hello\1; prepend to first non-whitespace char using lookahead: :s/\ze\S/hello (see here for info on lookahead/lookbehind; using lookbehind to append append to last non-whitespace :s/\s*\ze$/x (note that $ goes after the lookahead assertion)
3. Append to hello using lookbehind: :s/hello\zs/ world

File Tree

In neovim, C-n opens the file tree. (I'm not sure whether that is standard or my default config.) Selecting a file with enter sends it to one of the open windows: if one window it will use that, if more than one, it enumerates them a,b,c and you press a letter for the window you want. Use a nerdfont if you want file and folder icons to work properly. I use Hack Nerdfont in both Konsole and Windows Terminal.

Various

Paste setting into buffer

:call setreg("+", getbufvar("%", "&guifont"))

and then "+p to paste.

Command Line History

:q         -- open command line history
C-c        -- copy command to command line (C-c again to exit)
C-c C-c    -- exit command line history

Accessing buffers from command line

Copying matched lines to a position

:g/pattern/t10

will copy all matching lines to position starting at line 10
