Problem using 'M-.' 'insert-last-argument' in vi-keymap

[dezza]

With no other changes than

bleopt default_keymap=vi
ble-bind -m vi_imap -f 'C-c' discard-line
my/vim-load-hook() {
  bleopt keymap_vi_mode_show=
}
blehook/eval-after-load keymap_vi my/vim-load-hook

Demo using M-. insert-last-argument

$ echo foo
foo
$ echoecho  # M-. pressed after 'echo ', expected 'echo foo'

Do you have any idea why this could happen? It seems illogical to me as it works just fine with emacs keymap.

M-. is equivalent to ESC .. Here, in the vi editing mode, ESC (C-[) is taken by the command to "go to the normal mode (vi_nmap)". Then, by pressing M-., you essentially request to go to the normal mode and perform the command . (which repeats the previous edit).

Basically, the keybindings that contain the M- modifier are disabled in the vi editing mode by default because it conflicts with ESC. For example, you can see in §4.12 that M-. is only available in the emacs editing mode by default.

If you want to enable M-. in the vi editing mode, you can manually set up the keybinding as

# blerc
ble-bind -m vi_imap -f 'M-.' insert-last-argument

Or as explained here, you can enable all the meta bindings by the following setup:

# blerc
my/vim-load-hook() {
  bleopt keymap_vi_mode_show=
  ble-decode/keymap:vi_imap/define-meta-bindings # <-- add this line
}
blehook/eval-after-load keymap_vi my/vim-load-hook

Thanks a lot for the detailed explanation once again! Very helpful! Once again great project, I enjoy reading the code a lot as well as well as your memos, its very insightful!
