log failed tasks

[teto]

Please describe the problem you're trying to solve

I am trying to implement the suggested solution #1103 so I updated to nightly yazi, doing so I noticed the "28 tasks" in taskbar. Typing w prompted the task list with this result:

Typing "Enter" on one of the entry I got:

Preload task failed:
error converting Lua nil to function

Would you be willing to contribute this feature?

• Yes, I'll give it a shot

Describe the solution you'd like

I tried to get more context via less /home/teto/.local/state/yazi/yazi.log but the file remains empty (I had previously removed it).

I believe failed tasks should be logged in the log file. And maybe the UI could be improved to show more info:

• the tasklist could show if the task is running or failed ?
• I am not sure how the task name Run preloader 'mime' is supposed to help me.

Here is the excerpt from my config:

[plugin]
# https://yazi-rs.github.io/docs/configuration/yazi/#plugin
preloaders = [
	{ name = "*", cond = "!mime", run = "mime", multi = true, prio = "high" },
	# Image
	{ mime = "image/vnd.djvu", run = "noop" },
	{ mime = "image/*",        run = "image" },
	# Video
	{ mime = "video/*", run = "video" },
	# PDF
	{ mime = "application/pdf", run = "pdf" },
]

prepend_previewers = [
  # sync = true
  { name = "*.chunks", run = "chunks" },
  { name = "*.jsonzlib", run = "jsonzlib" },
  { mime = "audio/*", run = "zaz" },
]

is mime the name of a builtin preloader ?

Additional context

once again thanks a lot for this amazing software that never ceases to amaze me

Also I noticed that there were only two log levels "dbg" and "err" ? I think "warn" and "info" could be useful to help troubleshoot better the issues.

Hi, this is a breaking change for the upcoming Yazi v0.3 release. Please remove the mime plugin from your preloaders. See #1046 for details.

thanks it helped. I will let you close or let open depending on what you think of this part of my message

Do you mean to move the errors from the task manager to the log file for async tasks, or to keep the errors in the task manager and also copy them to the log file?

The reason I didn't add them to the error log before is that async tasks are often concurrent, making it hard to track their order in the log. But in the task manager, we can inspect and view errors in the list for each task individually.

Added to the Feature Requests as Group tasks in Task Manager by "Running"/"Failed"

Added some error notifications for the mime plugin, hoping to make the transition to v0.3 smoother :)
