Suggestions: Add scroll back as suggestion source. #19061
Description
Description of the new feature
This is based on Vim's out of the box completions where it sources the options from words in the open buffers. In this case it would pull the options from the active terminal buffer.
The case where I have found this really useful is when I have run a command that returns some data and now want to use part of the result in my next command. Ex. After running git log, running an additional command on one of the hashes and being able to auto complete it. Or After running --help on a command and then being able to auto complete the options.
Being able to define a regex for the filter was really useful to be able to have targeted completions for common stuff (hashes, addresses, command line flags) and then a catch all "default" one for words with > 4 chars.
Example Config.
{
"command":
{
"action": "showSuggestions",
"source": "scrollback",
"regex": "[^\\s]{5,}"
},
"id": "User.showSuggestions.2F7A7303"
},
{
"command":
{
"action": "showSuggestions",
"source": "scrollback",
"regex": "-{1,2}\\w(?:[\\w+|-])+"
},
"id": "User.showSuggestions.2F7A7304"
},
{
"command":
{
"action": "showSuggestions",
"source": "scrollback",
"regex": "\\b(?:0x)?[0-9A-Fa-f]{8,16}(?:`[0-9A-Fa-f]{1,16})?|\\b[0-9A-Fa-f]{7,40}\\b"
},
"id": "User.showSuggestions.2F7A7305"
},This what it looked like when I was testing what I had hacked together locally.

To quote Leonard Hecker (@lhecker), "This is disgusting in a good way"
We love it.

Yea this is super cool. I think a spec in the past called out "words from the buffer", but by god I can't find that spec now. And the regex matching? WAY cooler than anything I had come up with for that.
Assuming that this does regex smartly enough, then I'd ship the shit out of this (and I haven't even been on the terminal in like 10 months 😝)
