If you know how to build a Neovim plugin and allow for custom user keybinding, we can be friend 
The project
Few months ago, I decided to build something that would allow one to stay in Neovim while interacting with Taskwarrior. I didn’t want to reinvent Taskwarrior so I went with a simple script limited to my needs. After sharing it online, some people showed interest in this tool. As a result, I’ve added few features, but the remaining issue is to convert this script as a real Neovim plugin.
The features
-
Create/edit/update a task: Type #TW some text and use the default keybinding <leader>ta to create a task with some text as description, and add a task annotation in the form of “+line filepath” so you can easily access this task’s line from Taskwarrior.
The script will recognize the #TW pattern and ask for a project name, start and due date, and tags for this task. By default, the due date is set to start+1h to fit my specific needs, but you can change that by editing line 90.
All these fields are optional. The task will be added to Taskwarrior, and the task UUID will be appended to the line which will be commented.
-
Delete a task: Using the default <leader>td keybinding will delete the current line if it has a valid task UUID and remove the task in Taskwarrior. In the background, it will also add task’ annotations to all tasks below the current line.
-
Undo actions: Revert the last delete action with the default <leader>tu keybinding.
-
Retrieve task info summary: With the default <leader>ti keybinding, can call a notification window that will show you a summary of the task info.
-
Mark task as completed: Can be done using <leader>tc keybinding.
The missing steps
I’ve never built a real Neovim plugin. and this project was designed to be one more script to my collection. Hence, there are two issues remaining to be solved to convert this idea to a plugin:
- Create a correct git structure to allow for pulling by Neovim plugin managers.
- Allow for users to customize the keybindings.
The current script
local M = {}
-- Default
M.keybindings.keybindings = {
create_or_update_task = "<leader>ta",
task_delete = "<leader>td",
task_undo = "<leader>tu",
task_info = "<leader>ti",
}
-- Function to allow users to define their own keybindings
function M.setup(custom_keybindings)
-- Merge custom keybindings with the default ones
if custom_keybindings then
for action, key in pairs(custom_keybindings) do
if M.keybindings[action] then
M.keybindings[action] = key
end
end
end
-- Rebind the keys based on the defined keybindings
vim.keymap.set("n", M.keybindings.create_or_update_task, function()
M.create_or_update_task()
end)
vim.keymap.set("n", M.keybindings.task_delete, function()
M.task_delete()
end)
vim.keymap.set("n", M.keybindings.task_undo, function()
M.task_undo()
end)
vim.keymap.set("n", M.keybindings.task_info, function()
M.task_info()
end)
end

function M.annotation_update(line_nb)
if line_nb == 0 then
