Command Line Interface

REPL¶

lpy
#or
lpy -t #if you want to print python translation.

The REPL features Emacs-style keybindings (C-a, C-e, C-b, C-f, M-b, M-f, etc.), arrow key navigation, and persistent command history saved to ~/.lpy_history.

Auto-closing pairs¶

The REPL automatically inserts closing brackets and quotes when you type an opening one:

You type	REPL inserts	Cursor position
`(`	`()`	between `(` and `)`
`[`	`[]`	between `[` and `]`
`{`	`{}`	between `{` and `}`
`'`	`''`	between the quotes
`"`	`""`	between the quotes

Typing a closing character (), ], }) when the cursor is already before one will skip over it instead of inserting a duplicate.
Typing a quote (', ") when the cursor is before the same quote will skip over it.
Pressing backspace between an empty pair deletes both characters.

Run from source¶

lpy {filename}.lpy

Run translation¶

l2py {filename}.lpy

It just displays translation. (don't run it)

Run Tests (for development)¶

# in project root directory
pytest
#or
lpy -m pytest
