Just a parser for some strings. Under the hood it uses Megaparsec.

Usage

Build and run via nix command

❯ nix run .# -- kubectl get -o json pod web,haproxy
"running with input: kubectl get -o json pod web,haproxy"
Parser command is:
Kubectl (K {action = (Get,Pod {podName = Just "web,haproxy"}), output = Just Json})

❯ nix run .# -- kubectl get pods
"running with input: kubectl get pods"
Parser command is:
Kubectl (K {action = (Get,Pod {podName = Nothing}), output = Nothing})

❯ nix run .# -- kubectl get pods -o json
"running with input: kubectl get pods -o json"
Parser command is:
Kubectl (K {action = (Get,Pod {podName = Nothing}), output = Just Json})

❯ nix run .# -- kubectl get -o yaml pod web,srv1
"running with input: kubectl get -o yaml pod web,srv1"
Parser command is:
Kubectl (K {action = (Get,Pod {podName = Just "web,srv1"}), output = Just Yaml})

❯ nix run .# -- omg this is an another command
"running with input: omg this is an another command"
Parser command is:
Omg

GUI with the unix socket interface

You can run the parser in gui mode with a unix socker as an input interface. To do so provide a --gui as an only parameter.

nix run .# -- --gui

Then use socat or similar tool to send a message to the socket

echo "kubectl get pods -o yaml" | socat - /tmp/omgparser.socket

DevEnv

To fire up a development environmetn use nix develop and then cabal repl.
