it's text editor tuesday!
Welcome to the first installment of this exciting new feature! (Ok, and probably the last, because I forget about things and fear commitment.) Anyway, this is where I will share something I've recently discovered about editing text (in Vim or otherwise).
The other day, I decided I was tired of typing the datestamps on these
entries, so I stuck this in
(which is in my
#!/bin/bash echo -n '<h3>'`date '+%A, %B %e'`'<h3>'
And this in my
" use comma for the leader key let mapleader = "," " get a datestamp for a p1k3 entry " .-1 puts it on the current line, since :r reads onto the line below the " current one (or below the specified line - so here we're specifying the " one before the current one) nmap <leader>td :.-1r !today<CR><CR>
Silly, but it may illustrate a handful of useful techniques. Namely:
— I use
nmap so the mapping will only apply in
Reading about the distinctions between mapmodes opens up quite a few possibilities
for writing context-sensitive commands.
— If you define a leader, you'll have a place to hang custom keybindings without interfering with any of Vim's established ones. The comma seems to be a typical choice.
:r !foo, you can read the output of any given
shell command. I knew that before, but I had to skim the docs for ranges
to discover that you can say something like "current line minus one". Helpful
if you don't want the output from
showing up below where you're at.
echo -n if you don't want a trailing newline on the
