Functions

Line(matcher, indent=True)

source code

ContinuedLineFactory(matcher)
Create a replacement for Line() that can match multiple lines if they end in the given character/matcher. source code

Extend(matcher)
Apply the given matcher to a token stream that ignores line endings and starts (so it matches over multiple lines).

source code

constant_indent(n_spaces)
Construct a simple policy for Block that increments the indent by some fixed number of spaces.

source code

explicit(_current, indent)
Another simple policy that matches whatever indent is used.

source code

to_right(current, indent)
This allows new blocks to be used without any introduction (eg no colon on the preceding line).

source code

Variables

NO_BLOCKS = object()
Magic initial value for block_offset to disable indentation checks.

DEFAULT_TABSIZE = 8
The default number of spaces for a tab.

DEFAULT_POLICY = constant_indent(DEFAULT_TABSIZE)
By default, expect an indent equivalent to a tab.
