Shortcuts¶

As everyone is lazy and there is some things that are very boring to do while very easy to transform into a shortcut, here’s the dedicated module.

Everything can be done directly with the nsre.ast module but it’s shorter with a shortcut.

nsre.shortcuts.seq(s: Sequence) → nsre.ast.Node¶

Converts a sequence of items into concatenated Eq matchers. Useful to match a string exactly.

>>> from nsre import *
>>> re = RegExp.from_ast(seq('foo'))
>>> assert re.match('foo')
>>> assert not re.match('bar')

nsre.shortcuts.anything() → nsre.ast.Node¶: Matches anything. Conceptual equivalent of “.*” in regular regular expressions.
