4.4.1 - panic on startup

[Herby Gillot]

Describe the bug
Starting Ticker v4.4.1 for the first time seems to cause a panic?

panic: runtime error: index out of range [0] with length 0

goroutine 26 [running]:
github.com/achannarasappa/ticker/internal/ui.generateQuoteMsg.func1()
	/opt/macports-test/var/macports/build/_Users_herby_Source_macports-ports_finance_ticker/ticker/work/gopath/src/github.com/achannarasappa/ticker/internal/ui/ui.go:55 +0x140

To Reproduce
Steps to reproduce the behavior:

1. Build ticker 4.4.1 in a fresh environment, no pre-existing config or anything
2. Run it.
3. See panic.

Expected behavior
That runs and doesn't panic, or runs and exits cleanly (even with an error exit code if necessary).

Environment (please complete the following information):

• OS: macOS 12.1
• Terminal: iTerm
• Terminal Version: 3.4.14
• ticker Version: v4.4.1

Additional context
When run in the exact same environment and same way, v4.3.0 starts without issue.

Thanks for reporting this - this should be fixed in v4.4.3 but let me know if you're still seeing the issue

[Herby Gillot]

4.4.3 looks better, but when run with the print sub-command, we're still seeing panic:

$ .../ticker print
panic: runtime error: index out of range [0] with length 0

Thanks for finding that issue - I've added the missing validation in v4.4.4

[Herby Gillot]

OK thanks, confirmed that v4.4.4 is working. The MacPorts port for ticker has been updated. Closing this issue.
