Dependencies between lazy loaded plugins

[barthalion]

I want to lazy load CtrlP and its external plugin Funky. I expected the following snippet to load both CtrlP and Funky when :CtrlPFunky is called:

Plug 'ctrlpvim/ctrlp.vim', { 'on': [ 'CtrlP', 'CtrlPFunky' ] },
Plug 'tacahiroy/ctrlp-funky', { 'on': 'CtrlPFunky' }

Unfortunately it results in:

E492: Not an editor command: CtrlPFunky

It also happens with Airline and plugins it supports. Is there anything that can be done about it?

Hmm right, they shouldn't work. on option defines a proxy command for loading the plugin and rerunning the command from the loaded plugin. The second line in your case overrides the proxy command CtrlPFunky defined from the first line. It is possible that we make vim-plug not to override the previous one but to build the list of plugins to be loaded. Not sure if it's worth the effort though.

At the moment, you can define a proxy command yourself which calls plug#load() function.

Plug 'ctrlpvim/ctrlp.vim', { 'on': 'CtrlP' }
Plug 'tacahiroy/ctrlp-funky', { 'on': [] }

command! CtrlPFunky call plug#load('ctrlp.vim', 'ctrlp-funky') | CtrlPFunky

@barthalion Updated vim-plug to handle such cases. Please upgrade vim-plug and let me know if it doesn't work as expected. Thanks!

Thank you, works like a charm.

@junegunn What is the order between the plugins loaded by CtrlPFunky? The same as the line order?

Because in some cases, it's mandatory that the dependency gets loaded before the dependant.

For example with:

Plug 'ctrlpvim/ctrlp.vim', { 'on': [ 'CtrlP', 'CtrlPFunky' ] },
Plug 'tacahiroy/ctrlp-funky', { 'on': 'CtrlPFunky' }

The ctrlp plugin is loaded before ctrlp-funky plugin because it's in the line above ?

@alem0lars Yes.
