Interactive REPL

Launch the REPL by running devv with no arguments:

devv

  devv v0.1.0 — type a command or "help"

devv >

Features

Tab completion

Press Tab to autocomplete tool names and subcommands:

devv > js<Tab>
json     jwt

devv > json <Tab>
format   minify   validate

Command history

Use ↑ / ↓ arrows to cycle through previous commands. History persists across sessions.

Inline pipelines

Chain commands with | directly in the REPL:

devv > json format {"a":1,"b":2} | base64 encode
eyJhIjogMSwgImIiOiAyfQ==

devv > uuid | hash - sha256
a1b2c3d4...

Multi-line input

For large JSON or text, paste directly — the REPL handles multi-line input.

Commands

Command	Description
help	Show available commands
exit / quit / Ctrl+D	Exit the REPL
clear	Clear the screen
history	Show command history
alias <name> = <command>	Create a shortcut

Aliases in the REPL

Create shortcuts for commands you use often:

devv > alias jf = json format
devv > alias h256 = hash - sha256
devv > alias uu = uuid --count 5

devv > jf {"a":1}
{
"a": 1
}

Aliases persist across sessions. See Aliases for more details.

Tips

• The REPL auto-detects whether input looks like JSON and adjusts parsing
• Errors show in red with helpful messages
• Pipe output works: devv > uuid | hash - sha256 runs both steps inline
• Server tools work in the REPL too (requires devv login first)
