Allow notifications for systems without graphical capabilities

[ammgws]

Solves #80.

@frederickjh Would you like to test this?

[frederickjh]

@ammgws Thanks for your work on this. I set this up on a remote server to test.

I copied done.fish from your pull repository and installed fishpkg/fish-humanize-duration. I then set:

# Set up done for remote notitfication via Telegram
set -U __done_allow_nongraphical 1
set -U __done_notification_command "ta \$title \$message"

Running a command longer than the default 5 seconds would generate a notification via my ta.fish function using Telegram.

I then increased the time before done sends a message to one minute with:

# in milliseconds time before done sends a message
set -U __done_min_cmd_duration 60000

This works as we discussed in #80.

I also added:

## Commands not to send done messages for. Accepts a regex
# all git commands, except push and pull.
# nano
set -U __done_exclude 'git (?!push|pull)|nano'

As who wants to be notified when they finish a long edit on a document?

Consider adding something like the following to the documentation section Prevent specific commands from triggering notifications. Accepts a regex. something like:

Useful with set -U __done_allow_nongraphical 1 to prevent notifications for commands normally run interactively that you do not want to get done notifications for.

All in all a 👍, thanks!

Good to know it's working!

I'll leave docs up to @franciscolourenco as I think it's fine

I found this blog post that says with X11 forwarding turned on for a SSH connection that that notify-send should send the alert on the local machine from the remote ssh session.

I have not yet had time to test this with done but the blog post says the code they are using ,which was added to fish_prompt.fish, should be added to the Fish shell on the remote host for this to work.

### Notify on long command completion

# If commands runs >= 10 seconds, notify user on completion
if test $CMD_DURATION
    if test $CMD_DURATION -gt (math "1000 * 10")
        set secs (math "$CMD_DURATION / 1000")
        notify-send "$history[1]" "Returned $status, took $secs seconds"
    end
end

If this works with done I think that it would be a good idea to add this to the documentation.

[ammgws]

If it works you should open another PR for adding it to the docs

@ammgws If it was only that simple. I could not get this to work between two Ubuntu machines. One 16.04 and the other 18.04. I tried a number of settings locally in the ~/.ssh/config file and the remote /etc/ssh/sshd_config but could not get this working even thought X11 forwarding is working to start a GUI program on the remote server and have it appear locally in a window to work on.

The notifications are sent via the DBUS. I tried setting the DBUS_SESSION_BUS_ADDRESS environmental variable but this too did not work. I have gone back to using done with my custom command that sends the notifications via a Telegram chat.

If someone smarter that me can figure this out so that it can be documented, so be it. 😉 😎 👼

Closing due to inactivity
Sorry @frederickjh !

[franciscolourenco]

@ammgws What is the status of this? Is it working, reliable?

[ammgws]

I made this for @frederickjh, so will need his input

[frederickjh]

@franciscolourenco and @ammgws Sorry I didn't realize that more input was needed from me. I thought that my comments above were clear as to the status of this pull request.

To summarize what I stated above:

• I tested this and it works. I am using a custom command (per the issue request Add support for done notifications from remote servers via custom command #80) that posts to Telegram.
• What I tried that did not work, which is outside the scope of the issue is using the X10 forwarding via SSH.
• I would add this pull request to the project, as it is documented and ready to be committed.

Actually there was one thing I thought should be added to the documentation. From above:

Consider adding something like the following to the documentation section Prevent specific commands from triggering notifications. Accepts a regex. something like:

Useful with set -U __done_allow_nongraphical 1 to prevent notifications for commands normally run interactively that you do not want to get done notifications for.

@ammgws I've had a look at the PR and it looks good, so I would be up for merging this. Do you think it makes sense to add what @frederickjh to the docs, and if so would you mind doing it? Thanks!

[ammgws]

@franciscolourenco done 🐟

[frederickjh]

Any reason @franciscolourenco this has not yet been merged in? Looks like this has everything to close #80.

[franciscolourenco]

Sorry, only was able to get to this.

[frederickjh]

No problem @franciscolourenco. Sometimes life happens.
