Issues in starting off with this plugin

[Aster89]

Given what's written in README.md, my understanding is that after installing the plugin I'm ready to go.

Unfortunately, I'm facing some issues.

If I open a file which is read-only because it's not in any changelist yet and try to edit it, I am indeed prompted to open it in perforce:

File is read only. Attempt to open in Perforce?

and if answer yes the file is no more read-only, so I can keep changing and writing it. However the file has not been added to any changelist. Indeed, in the p4v client the file is shown in the workspace without the blue-ish color of modified files. Only dragging it to a changelist reveals it is modified.

If I do :P4edit, I get vim-perforce: File not under perforce client's root.

If I do :P4movetocl, the correct list of options is shown in the quickfix window, namely New changelist, default, and all named changelists. However, if I pick any of this choices I get the following

Error detected while processing function perforce#P4ConfirmMoveToChangelist[25]..perforce#P4CallMoveToChangelist[8]..<SNR>55_err:
line    2:
vim-perforce: Unable to move file to Changelist default

where default is a number if I've picked an existing changelist; if I had picked New changelist, a new changelist is created, but then the same error as above happens and the file is not added to the changelist.

Am I missing something obvious?

I guess this plugin is long dead.
