Template	This template does not require a rating on Wikipedia's content assessment scale.

Standard chess diagram template is a result of discussions and votings which took place in WikiProject Chess on Meta-Wiki. It is based on Template: chess position widely used in English Wikipedia. Both the template and the images of pieces were modified.

On this page I am going to place description of further modifications (if any). Please post your comments or questions in WikiProject Chess on Meta-Wiki. --Klin 21:50, 7 August 2005 (UTC)[reply]

Syntax

There are three standard chess diagram templates:

"Chess diagram" (square size 26x26 px)
"Chess diagram small" (square size 22x22 px)
"Chess diagram 8x10" (chessboard with ten columns, 26x26 px)
"Raumschach diagram" (5x5x5 board for Raumschach, 22x22 px)
"Omega Chess diagram" (10x10 board + 4 corners, 22x22 px)

The syntax is the same for all of them.

{{Chess diagram|=
| <alignment>
| <header>
| <a8> | <b8> | ... | <h8>
| <a7> | <b7> | ... | <h7>
...
| <a1> | <b1> | ... | <h1>
| <footer>
}}

Parameters:

<alignment> - defines horizontal alignment of the whole image, must be "tright" or "tleft";
<header> - the text which appears above the diagram, may be empty;
<a8>, <b8>, ... <h1> - define corresponding squares of the chessboard, see below;
<footer> - the text which appears beneath the diagram, may be empty.

A square is defined by the name of piece or empty parameter. The names of the pieces are those given in algebraic notation:

k = king
q = queen
r = rook
b = bishop
n = knight
p = pawn

There are also some fairy chess pieces available:

a = archbishop (knight + bishop compound)
c = chancelor (knight + rook compound)
f = upside-down king
g = upside-down queen
m = upside-down rook
e = upside-down bishop
s = upside-down knight
h = upside-down pawn
z = champion (for Omega Chess)
w = wizard (for Omega Chess)

These letters are combined with either "l" for Light=White, or "d" for Dark=Black. So "kl" is White's king, and "nd" is Black's knight.

An empty square is written either using underscores, spaces, or nothing at all. Two spaces are recommended. You can also use "xx" for a cross, "xo" for a black circle on an empty square or "oo" for a white one. Numbers can also be added to squares by using "x1" for 1, "x2" for 2, ..., "x9" for 9.

Examples

In the following examples the rows and columns are numbered. Because any text between "|=" and the next "|" is ignored, numbers and letters can be added without affecting output.

	a	b	c	d	e	f	g	h
8									8
7									7
6									6
5									5

Small diagram

This one may be useful in articles with many diagrams. It uses another template named "Chess diagram small".

Note: for some technical reasons the small diagrams have no header. The second parameter is just ignored, left only for compatibility.

Questions

How to use special symbols

How can I use symbol '=' in the caption? When I tried to use it directly, I see just something like "{ { 65 } }". I need this for GBR code. The caption should say in fact "GBR code of this study: =0323.12g3g1". Andreas Kaufmann 21:54, 9 August 2005 (UTC)[reply]

You can use <nowiki>=</nowiki> in the bottom caption. I'm not sure why it's necessary, but at least it works. Anyway, I updated the article to fix the problem. — Bcat ^{(talk • email)} 22:11, 9 August 2005 (UTC)[reply]

Use of template on another Wiki

Can I use this template on another wiki, by chance? Or no? I thought I'd ask first. -- Zalethon (Talk) 00:52, 19 December 2006 (UTC)[reply]

The template is under GFDL. You can use it, but need to put texts, which use the template, under GFDL as well. Andreas Kaufmann 14:06, 21 December 2006 (UTC)[reply]

Could you point me in the right direction for instructions on how to grab the template to install on another wiki? Oayfer 18:48, 8 February 2007 (UTC)[reply]

First you need to make sure that another Wiki is running on the same version of MediaWiki software as Wikipedia does (some older version might work as well). Then you need to copy the template:

Start article "Template:Chess diagram" in your Wiki
Switch to "template" on top of this page, do "edit this page", copy and paste the template text to "Template:Chess diagram" in your Wiki. Then you also need to download all chess pieces images and upload to your Wiki. Andreas Kaufmann 20:05, 8 February 2007 (UTC)[reply]

featured discussion / featured template

Was thinking, this template is a prime example of community colloboration to achieve an ingenious and pragmatic solution to a significant problem. Well, we do have featured articles, and featured pictures, but I was wondering, is there such thing as featured discussions or featured templates? Anyhow, it's been a long road since April 2004 since this was thought up, with a myriad of harmonic contributions from many Wikipedians to the entire template, lots of discovery and evolution of it since then, from the template itself, to different implementations of it (such as Template:Game of Go Position and Template:Xiangqi position which is under development mainly for the images), and then, across different languages. I would like to thank you all, for making this possible. Hurrah! :-) -- Natalinasmpf 07:15, 24 August 2005 (UTC)[reply]

FEN2Wikipedia converts FEN data (that you create directly or via a chess program) into the "Chess diagram" format.

use of Template:switch and Template:if

I was thinking, we can eliminate the need for separate templates for different boards totally if we could use the templates if and switch. We could even have the template switch boards at will:

Ie. we have another parameter, ie. "board=", that if not filled in will result in the default, if filled in, be casablanca, etc. We could even have it reversed (for each type), ie. it could be put in "perspective=" be "black" or "white", and would be the same template structure, just that the 64th parameter is now at the 8th, 32nd at the 31st, for a mirror image. However, if and case is very esoteric, so I need assistance with this. Any ideas? I also hope to introduce this for Template:Game of Go Position and Template:Xiangqi position (when it is completed). -- Natalinasmpf 18:09, 4 December 2005 (UTC)[reply]

I think we need something like for here to eliminate much of duplicate code. Is something like this possible in templates? Andreas Kaufmann 19:21, 4 December 2005 (UTC)[reply]

I don't think so - yet..."for" would require use of variables which can change - "if" simply uses parameters, which doesn't change as long as the argument to the template remains the same. A new wiki function should really make it easier to program templates. -- Natalinasmpf 21:55, 4 December 2005 (UTC)[reply]

We may iterate chess diagrams for switching background colours. I dont know if the foreach/for can read board sizes variables but if it works, we may use a for field iterator that recursively switches background colours. A switch that recursively changes them is already good enough - or what about a field that bypasses them? The next problem would be the variable counting. I have an idea that could make recursive calls quite nice...

Pseudocode:

Board diagram:
{{{chessfield_black|{{{size}}}|{{{1}}}|{{{2}}}|{{{3}}}|{{{4}}}|...}}}
{{{chessfield_white|{{{size}}}|{{{5}}}|{{{6}}}|{{{7}}}|{{{8}}}|...}}}

switch {{{boardsize}}} is greater than 2, do the same as above
...

template:chessfield_black:
{{{stone|{{{1}}}black|{{{size}}}}}}
switch {{{2}}} is neither empty nor unset, call chessfield_white with similar parameters to above

template:chessfield_white:
{{{stone|{{{1}}}white|{{{size}}}}}}
switch {{{2}}} is neither empty nor unset, call chessfield_black with similar parameters to above

template:stone:
just draw a table cell containing the stone with the specified background colour

Well, we still have a problem with counting, any ideas?

Got it! Ever thought of how powerful #sub might be? What if we use variables for each line and use the recursive algorythm as from above?

Pseudocode:

Board diagram:
{{chessline_firstblack|{{{pixels}}}|{{{1}}}}}
{{chessline_firstwhite|{{{pixels}}}|{{{2}}}}}
#switch {{{boardsize}}} is greater than 2, iterate as shown above...

template:chessline_firstblack:
{{chessfield_black|{{{1}}}|{{{#sub|{{{2}}}|0|2}}}|{{{#sub|{{{2}}}|2}}}}} //steal first two characters and append the trail
1 is size 2 is trailing stones

template:chessfield_black
{{stone|{{{1}}}|{{{2}}}black}}
1 is size 2 is piece identifer
#switch {{{3}}} is not empty, call chessfield_white template as shown above
3 is trailing stones

Note that we can now also use similar systems for working with abcdefgh and 12345678 :) please leave comments!

Any idea why this template doesn't work for me on another MediaWiki site?

I've copied across the Chess diagram template to a wiki on editthis.info. And I believe I've copied across the individual piece and square images.

Yet when I display the template, none of these images show up. Instead almost the entire screen is consumed by an orange block containing image ... instructions in each cell of the table. Thegn 11:34, 22 February 2007 (UTC)[reply]

Hm, images seems to be missing (see http://editthis.info/wiki/Template_talk:Chess_diagram) Are you sure that you uploaded images to the correct place? Andreas Kaufmann 19:15, 23 February 2007 (UTC)[reply]

Andreas, thanks for looking into this. Actually the wiki is at http://editthis.info/chess/Template:Chess_diagram . I believe I've copied across all the images, but I could be wrong. Thegn 22:38, 23 February 2007 (UTC)[reply]

OK, I've got it figured for you. Your wiki is using an old version of the MediaWiki software - version 1.5.5. The template was using default values for the arguments. However, the support for default values was added to MediaWiki in version 1.6. I have removed the default values now and the template seems to be functioning well, although it seems that you have forgotten to upload the pawn images. --ZeroOne (talk | @) 11:56, 24 February 2007 (UTC)[reply]

Many thanks. It's all now working, I think. Somehow, yes, I neglected to upload the Pawn images. Thegn 14:07, 24 February 2007 (UTC)[reply]

Black points of view

I was wondering if there is an (easy) way of showing the board (with coordinates) from black points of view. Thanks a lot for any info on this Voorlandt 20:44, 28 April 2007 (UTC)[reply]

No, there isn't. —This comment was added by Sibahi (talk • contribs) 21:36, April 28, 2007 (UTC)

As a matter of fact it is.. I might put the solution up here one of these days.. Its almost finished on my personal wiki (based on this template, for which I d like to thank everyone involved - & sorry for these multiple edits here, but I forgot to sign & date) - Gen 15:39, 21 July 2007 (UTC)

(outdent) Seems to me that all that's needed is to recreate, upload and use the two images showing the coordinates but with them reversed (originals here and here). I am not sure if the third piped argument in the 64 square listings needs to be changed (e.g., from "a8" to "h1"), but if so that is even easier. Baccyak4H (Yak!) 13:46, 17 August 2007 (UTC)[reply]

WordPress Port

For anyone who's interested, I've ported this most excellent template to WordPress. Details can be found right here. --Viper007Bond 10:41, 6 September 2007 (UTC)[reply]

Why is there so much padding

7									7
6									6
5									5
4									4
3									3
2									2
1									1
	a	b	c	d	e	f	g	h

Slav Declined

Notice the enormous gulf between the diagrams. It looks like the chess diagrams are set up to pad 6 pixels on top, and 10 on the bottom. This seems to leave a very unsightly gap when trying to stack diagrams (both paddings are applied) and causes diagram float layout problems on any page that wants to use several diagrams. The tleft and tright CSS classes already set margins (based on the font size, not absolute pixels as the diagram template does), so why do we pad so heavily (or even at all)?

Not working

User:Hairchrm posted a message on my talk page saying that the template is not displaying correctly on one of my userpages. I looked into this, and it would appear that this template is not displaying properly on any page. All empty black squares, and all normal pieces except the following are displaying as broken links:

White king on white square

Black king on black square

White queen on black square

Black queen on white square

Black rook on black square

Seeing as it is not just me who is having problems, I think it is likley that there is something wrong with the template. Is anyone else having problems? --GW_Simulations_{User Page | Talk} 17:04, 15 September 2007 (UTC)[reply]

Oh, by the way, the experimental SVG version (above) seems to work fine, so if there is a major and unrectifiable problem with the PNG version, then it could be resolved by replacing it with the SVG version. --GW_Simulations_{User Page | Talk} 20:44, 15 September 2007 (UTC)[reply]

I checked from the IRC, #wikipedia-tech says that there have been problems with the database/images all day and the problem is being looked into. So it has got nothing to do with this template per se and the problem should soon go away. :) —ZeroOne (talk / @) 23:56, 15 September 2007 (UTC)[reply]

Thanks. Black squares are displaying now, but the pieces are still not working. I hope it clears up soon. --GW_Simulations_{User Page | Talk} 12:23, 16 September 2007 (UTC)[reply]
