— A REPL to play with.
Wrap any command into a TUI, displaying its output in a scrollable area. Change parts of the command, hit enter to re-run the command again. Repeat.
You can build this project using Bazel on NixOS:
$ bazel build replay
$replay - interactive command line tool
Usage: replay [-v|--version] [-n|--var-name NAME] [-w|--watch FILE]
[-i|--from-stdin] COMMAND ARGS
Repeatedly run a command and display its output.
Available options:
-v,--version output version information and exit
-n,--var-name NAME name of the variable to replace (default: "input")
-w,--watch FILE watch FILE and re-run command automatically if it
changes
-i,--from-stdin read input from stdin, pipe into program continually
-h,--help Show this help text
$ replay jq --color-output input -r wikipedia.json
This command executes the jq tool and displays the output in a text area. Editing the expression in the input field and hitting Enter re-runs the command and displays the new output.
Pressing Esc exits the program, and prints the last output to stdout.
