Ability to run the CLI import in non-interactive mode

[CharlesB2]

During setup, we run the CLI import tool a lot, and it's very long to answer all questions. There should be a non-interactive mode with CLI arguments, as well as the ability to provide the API key through an environment variable.

👍 to this!

Agreed, this would be great to have when wanting to import lots of projects at once

Folks, PLEASE add this, I'm begging you. I just wasted hours of my day importing github issues, something I should have been able to script.

For anyone else struggling with this, here's a half-baked solution using expect.

The reason I say it's half-baked is that it's likely not going to be exactly right for your use case, and it certainly isn't what I'd call a well-written script. I have literally never used expect or tcl before today, and I welcome any suggestions for improvement. But hopefully it's enough to give you a starting point for automating importing multiple repos.

#!/usr/bin/expect -f

set force_conservative 0 
if {$force_conservative} {
	set send_slow {1 .1}
	proc send {ignore arg} {
		sleep .1
		exp_send -s -- $arg
	}
}

set repos {
repo-1
repo-2
repo-3
etc...
}

foreach repo $repos {
	puts "processing repo: $repo"
	set timeout -1

	spawn linear-import
	match_max 100000

	expect "*Input your Linear API key (https://linear.app/settings/api)"
	send -- "[your-linear-api-key]"

	expect "*Which service would you like to import from?"
	send -- "GitHub\r"

	expect "*Input your personal GitHub access token (https://github.com/settings/tokens, select `repo` scope)"
	send -- "[your-github-token]"

	expect "*From which repo do you want to import issues from (e.g. \"facebook/react\")"
	send -- "$repo\r"

	expect "*Do you want to create a new team for imported issues?"
	send -- "n\r"

	expect "*Import into team:"
	# down arrow 5x then enter is what I needed, you'll almost definitely need to adjust this
	send -- "\033\[B"
	send -- "\033\[B"
	send -- "\033\[B"
	send -- "\033\[B"
	send -- "\033\[B"
	send -- "\r"

	expect "*Do you want to import to a specific project?"
	send -- "n\r"

	# you might have to comment this out
	# I couldn't figure out how to handle optional prompts
	expect "*Do you want to include comments in the issue description?"
	send -- "y\r"

	expect "*Do you want to assign these issues to yourself?"
	send -- "n\r"

	expect "*Assign to user:"
	# as above, adjust the number of down arrows you need to use
	send -- "\033\[B"
	send -- "\r"

	expect eof
