[vim plugin] Bad Request about tern

[marijnh]

The problem appears to be that the counter I'm using to detect changes (undotree()['seq_cur']) is only updated when insert mode is left. So if you make two requests in a single insert mode episode, the second won't notice that the buffer is changed and updated text should be sent.

Does any solution come to mind? Maybe always send when in insert mode, since the user is probably typing.

Is there a way for a script to find out whether insert mode is active? I can't seem to find anything.

In Vim, insert mode is only used for typing, otherwise the user would be in normal mode (modulo some people who insist on staying in insert mode to pretend that Vim is modeless...). While completing, insert mode is always active. But when I enter :TernType, I've left insert mode, so shouldn't tern receive updated content then?

You could use the InsertEnter/InsertLeave events to flag insert mode for scripting, if that helps.

Attached patch should help. Somewhat awkward, but I guess we have to work with the tools that vim gives us.

[clausreinke]

If you find the events awkward, you could simply add a keyword parameter indicating mode to tern_runCommand. The call in tern_ensureCompletionCached should be the only one from insert mode.
