struct-tools

Printing dicts (and objects) legibly: keys aligned, arrays summarized, nested reprs indented. Plus attribute (dot) access.

• aligned: render key-value pairs with the keys aligned, summarizing arrays and indenting nested reprs to their key.
• AlignedDict: a dict printed by aligned.
• DotDict: the same, plus attribute (dot) style access.
• AlignedRepr: provides __repr__ (for subclassing) via aligned.
• get0: the first value of a dict.

TODO

• Put DotDict and AlignedDict each in their own module

Changes in 0.3.0

The printing was replaced by the (much smaller) repr written for MiniRes, which now shares it. Consequently:

• The package is now only about printing dicts (plus dot access): the dict/list utilities -- intersect, complement, prodct, transps and the transpose_* family, deep_getattr, deep_hasattr, flexcomp -- are gone. They originated in, and are already vendored by, DAPPER (dapper/tools/struct.py). 595 -> 190 lines.
• aligned and AlignedRepr are new; NicePrint is an alias of the latter.
• printopts is gone bar indent; MIN_LINEWIDTH too.
• Keys are no longer quoted, __str__ is no longer distinct from __repr__, and the line width is fixed (70) rather than the terminal's, so that output is reproducible.
• Recursion is guarded by the stdlib's reprlib.recursive_repr (...), rather than by hand.
• numpy stays an optional, lazy dependency: arrays are summarized if it is already imported, and it is never imported on its account.
