plenary.job doesn't work with fzf

[tjdevries]

isn't fzf waiting for something to input to it so that it can output something?

You can try piping something into the job if you want perhaps. Or connect one job to another. I think I had an idea about do unix style "piping" between jobs. I can investigate that.

fixed w/ new writer parameter

I think there was a misunderstanding here, can we re-open this?

The example command was run with the --filter option, which is meant for scripting and does not start an interactive process. WIth that option, it behaves more like fd but using the fuzzy algorithm. If you run it in a terminal, it outputs newline separated relative file paths for the matches and exits.

@smolck did you find a solution to this issue?

no it cant be reopened. the example was missing the pipe and that features was added with the writer interface

local Job = require("plenary.job")

Job:new({
  command = "fzf",
  args = {"--no-sort", "--filter", "thing"},
  on_stdout = function(_, data, _)
    print(data)
  end,
  on_exit = function(_, code, _)
    print("exit", code)
  end,
  writer = Job:new{
    command = "fd",
  },
}):start()

Thanks for the quick response @Conni2461 . I don't get it though, why would you pipe the fd command into fzf? The fzf --filter thing command is the complete command I am trying to run, and it exits immediately without input when run from a terminal. I don't need to add the fd command.

I'm trying to investigate, it seems like fzf is doing something with stdout/stderr that is unexpected. It works fine at the command line but never calls those methods when run in the job.

EDIT: Also, the above example produces errors when I try to run it:

@cseickel, were you able to use this solve this with the writer option?

[rohit-kumar-j]

@Conni2461, is there a way to do something like:

writer = Job:new{
    command = "stdin", -- for an interactive experience.. like a prompt-buffer?
  },
