A simple function to determine what format page a page in document has. Parameters provided are width and height in float or integer format.

Return is a string like "A4-P" or "Letter-L" when an exact fit is found. If not, information is provided as a string like "width x height (other), closest <format> width x height". The closest format in this case is determined by minimizing the sum of absolute differences of width and height with a table of official formats.

Formating strings (print a table) (Batch)

2013-06-18T07:52:03-07:00

Batch recipe 578562 by greg zakharov (format, string, table).

As you know there are no escape characters such as "\t" in the windows command language but it does not mean that we can not format text. Command prompt has its own tricks. At firstly, you need declare enabledelayedexpansion after setlocal command in your batch file to get access for some interesting things; secondly, use <code><nul set /p "str=[string]"</code> construction which is equal print function in C language. OK, next batch file print multiplication table.

Cheap-date trick; a different way to parse (Python)

2012-03-06T14:08:10-08:00

Python recipe 578064 by Scott S-Allen (cheap, date, format, grep, parse, regex, sharp).

... a light meal with a heavy dose of "tutorial mash" on the side.

In the constructive spirit of "more ways to solve a problem"; this is a portion of my lateral, occasionally oblique, solutions. Nothing new in le régime de grande, but hopefully the conceptual essence will amuse.

Initially started as a response to recipe 577135 which parses incremental date fragments and preserves micro-seconds where available. That script does more work than this, for sure, but requires special flow-control and iterates a potentially incumbering shopping list (multi-dimensional with some detail).

So here's a different box for others to play with. Upside-down in a sense, it doesn't hunt for anything but a numerical "pulse"; sequences of digits punctuated by other 'stuff' we don't much care about.

Missing a lot of things, intentionally, this snippet provides several examples demoin' flexibility. Easy to button-up, redecorate and extend later for show, till then the delightful commentary makes it hard enough to see bones already -- all six lines or so!

Note: The core script is repeated for illustrative purposes. The first is step-by-step, the second is lean and condensed for utilitarian purposes. It is the second, shorter, version that I yanked from a file and gussied up.

Render tables for text interface (Python)

Python recipe 577202 by Denis Barmenkov (format, table, text). Revision 2.

Sometime pprint module is not enough for formatting data for console or log file output. This module provide function which fill the gap.

Sample function call:

nums = [ '1', '2', '3', '4' ]
speeds = [ '100', '10000', '1500', '12' ]
desc = [ '', 'label 1', 'none', 'very long description' ]
lines = format_table( [(nums, ALIGN_RIGHT|PADDING_ALL, 'NUM'), 
                       (speeds, ALIGN_RIGHT|PADDING_ALL, 'SPEED'), 
                       (desc, ALIGN_LEFT|PADDING_ALL, 'DESC')] )

Output:

=======================================
| NUM | SPEED | DESC                  |
=======================================
|   1 |   100 |                       |
|   2 | 10000 | label 1               |
|   3 |  1500 | none                  |
|   4 |    12 | very long description |
