Report Success/Failure in the quickfix title

[mvanderkamp]

Per this comment, I've added the status label part of the message to the quickfix title. This label is only added when the command completes, and when updating the quickfix list only the initial part of the title (before the status label) is used to check against the current quickfix list, so updates to the current quickfix list should still work as expected.

The status label is currently only added under the same circumstances that the normal "Success"/"Failure" message is shown.

Been using this for a while with good results. I would have merged it some time ago, but (adapter/123) (Success:0) is just too much of a mess, and I haven't managed to think through what a replacement might look like. Eliminating the Success/0 redundancy would be a good start.

[mvanderkamp]

Just to be clear, are you thinking:

1. Only ever show the word "Success" or "Failure"
2. Only ever show the exit code
3. On success show only either the word "Success" or the status, otherwise show both word and code since the exit code can be useful in case of failure

[tpope]

Undecided. My initial instinct was something like (adapter/12345=>0) but that ASCII arrow is pretty ugly (and I want to stick to ASCII to maximize portability, so something like ⇒ or → is off the table).

[tpope]

I am okay to rethink the adapter/12345 part too, just so long as we retain something parseable and distinct.

What's the use case for showing handler and pid information in the title after the process has completed? Programmatically it is used to continue making sure that we uniquely identify lists in the quickfix history so that we can properly update them, but what does a user do with that information at that point?

If it's just for uniquely identifying quickfix lists, we could use the id of the list or set the context to achieve the same thing, and just show the exit status in the title instead.

PID and adapter are in the title for continuity with the start message, and they're in the start message because they're useful for understanding what's going on. Continuity could be fulfilled by the PID alone though, so that opens things up a bit. I wouldn't even say continuity is a hard requirement, but I do like that if you run the same command several times in a row, each title is unique, helping to reduce confusion.

We're currently in the process of phasing out Vim 7 support, but even when we get to an 8.0 minimum version, that's not enough to guarantee support for the quickfix ID or context.

[mvanderkamp]

Okay, that all makes sense, thank you!

What do you think of a format like: (12345/Failure[127])

• Use the title up to (12345/ to find quickfix lists
• While the command is running, put a _ placeholder in for the result label: (12345/_)
• Only show the [127] exit code part if the command failed.

Also: should this be how the postfix is always formatted, or just for the quickfix title?

[tpope]

Ngl I hate that ([]) nesting more than =>. Do we really need the exit code?

One thing I will say is that if we stick with Success/Failure, the natural placeholder is Running.

[mvanderkamp]

I'm not attached to the exit code, I just thought it would be useful- I don't mind ditching it.

the natural placeholder is Running.

Haha good call, of course it is!

[mvanderkamp]

Sorry I didn't notice there was a merge conflict! I think I've resolved it correctly (removed the added space before ! in the call to echo_truncated on line 1257 of autoload/dispatch.vim since the label is not shown in that part of the message anymore).

[tpope]

Still not ready to act on this, but I can assure you I consider this mandatory for the next stable release, as it's impossible to tell if the job adapter is finished without it, assuming you miss the status message. A merge conflict won't block this.

[Kamilcuk]

I'll just drop by for a +1

[tpope]

I still use the tmux adapter the majority of the time, but rest assured whenever I use the job adapter this continues to bother me!

We're currently in the process of phasing out Vim 7 support, but even when we get to an 8.0 minimum version, that's not enough to guarantee support for the quickfix ID or context.

One advantage of the long delay is enough time has passed that I think I'm willing to cave on this. I'm pushing a change to require the quickfix id for asynchronous dispatch to see if anyone complains.
