Feature Request: Inotify module about elvish HOT 4 CLOSED

looking into the golang file watching ecosystem, it seems the list of events above is likely more verbose than needed.

I plan on using fsnotify, which means this will be cross-platform, but will only support Create, Write, Rename, Remove, Chmod events

from elvish.

Regarding the design itself:

• There's precedent in accepting duration strings (as accepted by time.ParseDuration) in sleep.

• There's no precedent in outputting timestamps though. It should probably be another basic data type, like numbers.

• debounce can be a general-purpose command, so you'd do something like watch ... | debounce 1s.

But...

However, developing the behavior above as a separate command, that implements all the logic defined above, and simply outputs json, could be wrapped relatively easily by elvish, and might make more sense than an addition to the stdlib.

I agree with this :) Developing a command that is based on fsnotify and outputs JSON makes a lot of sense.

I do like the idea of having this well integrated into Elvish - the output is structured, so it's quite clumsy in traditional shells but very easy in Elvish. If you'd like to build an Elvish module that wraps it, that's something I'm thinking about in #1607 (case 3).

Makes sense :). I have a few thoughts about #1607 I'll leave there.

Note that there is no reason this needs to be limited to working on Linux. The fswatch command shows that it is possible to support Linux, the various BSDs (including macOS), and Windows. In fact, if you're going to write a module that wraps an external command to make using the external command easier to use with Elvish I would argue that fswatch is a better choice given that it also works on all the platforms supported by Elvish.
