OneCommand

A python script to generate one-command contraptions in Minecraft 1.9, by myself and yrsegal.

User Interfaces

The GUI

Windows Executable

This Tk-written wrapper for the OneCommand library allows you to edit your commands in a clean GUI. For those not on windows, you would simply run oneCommandGUI.py.

Sublime Text Plugin

A OneCommand syntax/generator has been written as a plugin for Sublime Text. You can check it out above, or download via Package Control.

The Command Line

oneCommand.py has been designed from scratch with the CLI in mind. The arguments are as follows:

  • -m {m,i}, --mode {m,i}: Choose whether to have the contraption activated manually (m) or instantly, upon deployment (i).
  • -f [FILE], --command_file [FILE]: Use a file as input. Without an argument, it will pull from STDIN.
  • -a, --alternate-parser: Use the old parser.
  • -C, --no-copy: By default, OneCommand will copy the output to the clipboard. This argument prevents that behavior.
  • -q, --quiet: Silences all output besides the command itself.
  • -v, --verbose: More detailed output.
  • -O, --no-output: Doesn't dump the command to STDOUT. If -O and -C are used, the command will not be outputted at all.
  • -h, --help: Shows the list of arguments.

The Syntax

Most of the differences between the OneCommand syntax and regular commands lie in the prepends.

  • INIT: as a prepend will make the command only run once, when you run the command.
  • COND: as a prepend will make the command only run if the previous one was successful. Not recommended to use on the first command, nor the first INIT: command.
  • REPEAT: as a prepend will make the command in a repeating command block. This is included to allow for different-speed clocks, and similar functions.
  • BLOCK: as a prepend will use the following command (format minecraft:BLOCKNAME:DATA) as a normal block instead of a command. This can be used to visually seperate parts of a module; remember that REPEAT: must be used afterwards to carry the signal.

\ appended to the end of a line will append the next line to the current line.

There's also the DEFINE: syntax, similar to the C #define directive. This allows simpler-to-read blocks of code to be written.
The syntax is DEFINE: identifier replacewith. You can then use this by calling out, anywhere in your code, $identifier.
As with C, DEFINE: can be used to make macros. For example, DEFINE: example(argument) say |argument| and $example("hello") will give you say hello. There's also UNDEFINE: which will remove that variable's definition.

IMPORT: will import the .1cc file of the same name. IMPORT: test will import the file named test.1cc.
