BashCraft

First release! Changelog for 1.0.0:

Chains

• &&, || and ; with bash's rules; groups ( … ) that nest; quotes and \ escapes.
• [n] numbers on errors, so you can tell which command in a chain failed.
• Chains in chat, the console, command blocks and function files; /sh reports the chain's result to command blocks and /execute store.
• Transparent mode: chains typed without /sh, when every command after an operator starts with /.

Pipes

• | passes coordinates, numbers or text to the next command, appended or placed with {x} {y} {z} {value} {result}.
• grep, each, store and surface; real lists from /list, /tag … list, /team list, /scoreboard players list and NBT lists.

Variables

• x=…, $x, ${x}; your own set and the global set (my., global.); $?; $( … ); unset; echo.
• Kept in command storage bashcraft:vars, shared with datapacks.

Aliases and history

• alias NAME = BODY with $1…$9, $@, $# and ${N:-default}; global aliases for operators; unalias.
• !!, !PREFIX and history for the lines you type.

Time

• sleep with /schedule's units; & for parts of a chain that wait on their own; jobs and kill %N.

Client companion (optional)

• Chat-box colours for chains, BashCraft error hints, tab completion inside chains and command blocks, alias names.

Safety

• Chains never grant permissions; chat commands are refused inside typed /sh lines; values players control must be plain in trusted chains; limits on chain length, nesting, commands, sleeps and waiting chains, all configurable.
