This is awesome, great work bugen!

I've created a package in Wasmer [1] to showcase this tool (also, it will do the processing fully sandboxed thanks to Wasm!)... hope you all like it! (here's the PR [2])

  # Install Wasmer
  curl https://get.wasmer.io -sSfL | sh
  # Add ppp alias
  alias ppp="wasmer run syrusakbary/pypipe@0.1.0 -- "

And then, run it normally:

  $ cat staff.txt |ppp 'i, line.upper()'

wow that wasmer thing is _SLOW_.. we are talking about 57x time slow! (granted most of this is likely startup delay). Here is a random benchmark with warmed-up cache:

    $ time cat /var/lib/dpkg/status | wasmer run syrusakbary/pypipe@0.1.0 -- 'i, line.upper()'  | wc -l
    39175
    real    0m5.761s
    user    1m15.071s
    sys     0m4.838s

vs regular python:

    $ time cat /var/lib/dpkg/status | python3 pypipe.py 'i, line.upper()'  | wc -l
    39175
    real    0m0.107s
    user    0m0.096s
    sys     0m0.026s

and the wasmer install procedure.. not a deb file in sight, adds itself to ~/.bashrc (of course...) and apparently requires two environment variables to even work.

Compare this to OP's instructions: (1) check out the repo (2) execute the file directly.

Not sure why would anyone want wasmer for simple command like tools like those.
