    <p>afaik <code>reindent.py</code> (available in the standard python examples) has a tokenizer allowing it to do smart reindenting based on the indentation level rather than on the number of spaces osed per level (which can vary in bad code)</p> <p>unfortunately it enforces 4-space indentation, but i want tabs, because 1 tab == 1 indentation level is more logical than x spaces.</p> <p><a href="https://stackoverflow.com/questions/338767/tool-to-convert-python-indentation-from-spaces-to-tabs">this</a> question has no suitable answer:</p> <ul> <li>i don’t care about pep-8 (i know how to write my code)</li> <li>vim is installed, but <code>:retab!</code> doesn’t handle inconsistent indentation</li> <li>all tools convert spaces used for alignment (!= indentation) to tabs, too.</li> </ul> <p>one way would be to use reindent.py and afterwards doing sth. like:</p> <pre><code>#!/usr/bin/env python3 from re import compile from sys import argv spaces = compile("^ +") multistr = False for line in open(argv[1]): num = 0 if not multistr: try: num = len(spaces.search(line).group(0)) // 4 except AttributeError: pass print("\t"*num + line[num*4:-1]) if line.count('"""') % 2 == 1: multistr = not multistr </code></pre> <p>but that’s rather hacky. is there no non-zealot version of reindent.py?</p> <p>PS: why suggests the highlighting that <code>// 4</code> is a comment instead of a truncating division?</p> <hr> <p>The following script should do the trick, but either i missed sth., or tokenize is buggy (or the example in the python documentation)</p> <pre><code>#!/usr/bin/env python3 from tokenize import * from sys import argv f = open(argv[1]) def readline(): return bytes(f.readline(), "utf-8") tokens = [] ilvl=0 for token in tokenize(readline): if token.type == INDENT: ilvl+=1 tokens.append((INDENT, "\t"*ilvl)) else: if token.type == DEDENT: ilvl-=1 tokens.append(token) print(untokenize(tokens).decode('utf-8')) </code></pre>

    1. COabout PS: you know `//` is a comment marker in a lot of languages... don't be too zealot... :)

    2. COi know i tend to be zealoty myself sometimes, but this code is highlighted as python, a language in which `//` means “truncating division”. highlighting everything after this operator as comment (css-class `com`; gray) is plain wrong.

    3. COYou start from the idea that syntax higligher checks question tags... which is not true. :)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
