Error after update/install

[khalidchawtany]

Each time I run any of PlugUpdate / PlugInstall command, I get the error below. After the error message by a second, it disappears, as if is feed to it, to simulate press Enter prompt.

Error detected while processing function <SNR>2_job_handler..<SNR>2_tick..<SNR>2_upd
ate_finish..<SNR>2_finish..plug#end:
line   50:
E183: User defined commands must start with an uppercase letter

Looks like you have invalid config in your vimrc, i.e. lowercase command in on option. Please post your vimrc.

Awch :(
You were right, I had 'on': ['obsess'] instead of 'on': ['Obsess']

Sorry for the noise, and many thanks for your great plugins ;)

Just one small suggestion:

Can you make the plugin show a more informative error message?

Well, I think the message is pretty straightforward, but I realized that there are more fundamental problems.

1. You don't see the error message upfront when you start vim.
2. The current code was written to check if an argument to on option starts with an uppercase letter and ignore it otherwise. However, cmd =~ '^[A-Z]' can return true even if cmd starts with a lowercase letter when &ignorecase is set, which is what you just experienced.

Both problems are trivial to fix. I'll fix them.

EDIT: I had some facts mixed up, but anyway some improvements needed.
