padfixer.lua -- read "Poker After Dark" wikipedia source, produce summary tables
2009-06-22 WF Note no '#!' line since not on usual box
This program allows a quick update of the Wikipedia "Poker After Dark" (PAD) "Stats"
section after additional information about a tournament has been added to the page.
To update the "Stats" section:
1) Have Lua available; see lua.org If you have a C or C++ compiler you can download
and install Lua on your computer in less than five minutes.
2) Copy/paste this page (or the source for it) into a text file named "padfixer.lua"
on your computer.
3) Edit the full page for "Poker After Dark" and copy/paste its full text into a text
file named "padinput" on your computer. Be sure to use the "Back" button to avoid
changing the PAD page.
4) Note the number of "seasons" of PAD that have been added to the page. At this
writing the number is 5. This number will be designated "nSeasons", below.
Ditto the last week of play "nWeek" (this/these should be fixed).
5) From a command line, run:
lua padfixer.lua nSeasons nWeek <padinput >padoutput
This reads the source of the PAD page from "padinput" and produces a new "Stats"
section in "padoutput".
6) It is probable that one or more errors/inconsistencies in player names will be
discovered by the program. The program requires that all occurrences of a player's
name in the tables be identical. Fix the "padinput" file accordingly. You might
also want to fix the tables on the PAD page itself to limit this problem in the
future.
7) When the program has run correctly, edit the PAD "Stats" section, delete all its
content, then cut/paste the "padoutput" file into it, completely replacing it.
8) "Show preview" the changes and check them before saving them.
Potential problems:
- The PAD source has some unicode characters so you have to select UTF-8 encoding
in order to save it. This does not affect the "Stats" tables now but may if we
get, for example, a player with an umlaut in his/her name. Plain Lua is rather
dumb about this. Maybe someone will be moved to translate this program into,
say, Python?
- The complete "Stats" section is reproduced. When accepted edits are made to it,
even if the table contents remain the same, the "forms" in the below source code
will have to be changed.
I plan to additionally sort on the other finishes columns, sometime or other.

-- "Stats" forms sans table contents ([[ and ]] for multi-line strings)
local form1 = [[
==Stats==
These statistics are meant to help readers judge the players' relative performances in the main type of event featured on "Poker After Dark": The six-player winner-take-all tournament. So, with the exception of the "Total appearances" column, the statistics omit all "Cash Games" (which do not even have declared winners) and the one "Heads Up" event played so far (Season 4, Week 3, won by Phil Hellmuth). The notations (x2) and (x3) mean the player achieved that placement two or three times, respectively.
:''Stats updated to reflect results through Season %d, Week %d.''
