User-defined text objects are not correctly repeatable by `.` about vim-textobj-user HOT 11 CLOSED

Asked vim_dev: https://groups.google.com/d/topic/vim_dev/EA0jA9xLMsQ/discussion

from vim-textobj-user.

Idea: Is it possible to replace the :normal v trick with some combination including v:operator?

from vim-textobj-user.

Kana, while investigating this issue I have found some kind of workaround. It's also used in matchit.vim.

Change the first line in the script above to

onoremap iw v:<C-u>call Select()<Return>

Note the v. Now . works correctly in the normal case. Only after delfunction the behaviour becomes strange (deletes one character).

onoremap iw v:<C-u>call Select()<Return>

Thank you for the trick. And thank you also for great help on the thread in vim_dev. I wonder why the trick enables repeatability...

However, I don't want to use it. Because:

• o_v is to force an operation to work characterwise, or to toggle inclusive/exclusive. Using the trick disallows users to use these features. Though Vim currently doesn't provide API to detect o_v, o_V and o_CTRL-V from Vim script, but it's not difficult to add such API. I already proposed a patch, but it is not included yet.
• vim-textobj-user allows custom text objects to cancel the current operation. If a custom text object is invoked in Operator-pending mode and the text object couldn't find a valid target, vim-textobj-user doesn't move the cursor to target no text. This behavior can be emulated with the following key sequence: d:<Return>. But the trick disallows to cancel the current operation. If o_v is given to the current operator and the cursor doesn't move, a character under the cursor is treated as a target of the operator. For example, dv:<Return> delete a character under the cursor.

Repeatability is important, but cancelability is also important. Using the trick sacrifices cancelability, and it breaks backward compatibility of vim-textobj-user based plugins. And the repeatability problem seems to be caused by the internal of Vim, as you described to the thread in vim_dev. Therefore, I don't want to use the trick directly.

What about Tim Pope's vim-repeat?

@wellle This has been discussed at length, e.g.

Oh that's very interesting. Thank you for your work on this issue!

By the way: I believe this issue has been resolved in Vim 7.3.918.

Yes that's true, it's working 👍
