Game Tag Bugs

Ugh! Page 3... i better quote the message i was addressing...

[Vinny]

test 2 without the numbered pieces

[Vinny]

and what's the point of aliasing?

[CrystyB]

Vin: you typo'ed -d2...

2. Ah, i guess looking at a post made through goboard made me believe we aren't supposed to see the moves on the right...

[Vinny]

doh!

nm jeep, my bad.

[CrystyB]

[jeep]

I thought about mentioning the spaces and comma thing, but I am thinking about how to remove that restriction. Since the alias is enclosed in braces, it shouldn't be too difficult, I just can't quite get the regular expression perfect.

As to the PS, is that good or bad?

-JEEP

[CrystyB]

Nah, it was just the pretext i needed to go edit that wiki page on mafscum. I'm almost done, but... i can't find a way to upload my pic (i have it in my glpics account until further developments) and put it in the page...

New idea: something i kinda dislike about the subtags is that no matter their order, the player with white stones will always be put above the player with black stones. Which is ridiculous, IMO.

[jeep]

Heh, true I look for the tags in a fixed order because it's easier than looping through each existing tag. For tagless games, it's extra processing, but at some point it becomes more efficient, so I suppose I'll change it eventually.

The reason it's ordered that way for black and white is because that's the order they are listed in the PGN spec. and I just reused the same code.

-JEEP

[CrystyB]

I had a hunch that was the reason. But this isn't even remotely supposed to be PGN, so why not do it the other way around? Not everybody knows that black starts a game of Go...

And you haven't answered my inquiry about pictures in wiki... Am i supposed to simply link to it, instead of including it in the page (as in an IMG-like kind of way)?

[jeep]

Oh, sorry.

I have uploads turned off right now. I'll turn them on when I get home. You can link it for now, if you wish.

-JEEP

[Chuck]

We should have generic game tags where the user supplies the images for the board and pieces. The user specifies within the tag where in the board image the center of each piece image goes. If pieces overlap the last one placed would be on top. Then we would never need to add more game tags.

[CrystyB]

OMFG!!! I tried to put the URL, to let the wiki engine come up with the link, and instead got the pic!!!

Jeep, thanks for the thought, but even if you would've enabled uploads, i would've had no idea how to use them...

@ Chuck

[CrystyB]

Finally! A real coding fluke for a change...

[jeep]

Yeah, I fixed that, but haven't release it. I hoped no one would notice

-JEEP

[Vinny]

[CrystyB]

i never really started to use them, so i know almost nothing of RegExps...

But, Vin, i wonder what would your Exp give from "start{text1}middle{text2}end"?

[mathgrant]

Considering how you play Chess4 all the time, I'm surprised you never considered the possibility that WHITE could be moving his pawns UP. The H2 pawn has never moved. :-p

Well, that's not really what I need Vinny.

I need to figure out how to get all the moves separated... the string will look like:

Game tags have been updated to handle the couple bugs we found and to add the capability to add titles to chessvariants and go.

[Vinny]

for Crysty, if you want to learn regexp pattern, here's a quick starting guide.

* Matches the previous character zero or more times
+ Matches the previous character one or more times
? Matches the previous character zero or one times
. Matches any single character except the newline
^ Matches the start of the input
$ Matches the end of the input
x|y Matches either first or second character listed
(pattern) Matches pattern
{number} Matches exactly number times
{number,} Matches number, or more, times (note comma)
{num1, num2} Matches at least num1 and at most num2 times
[abc] Matches any character listed between the [ ]
[^abc] Matches all characters except those listed between the [ ]
[a-e] Matches any characters in the specified range (a,b,c,d,e)
[^K-Q] Matches all characters except in the specified range
\ Signifies that the next character is special or a literal.
\b Matches only on a word boundary
\B Matches only inside a word
\d Matches only on a digit
\D Matches only on a non-digit
\f Matches only on a form feed character
\n Matches only on a new line
\r Matches only on a carriage return
\s Matches only on a blank space
\S Matches only on nonblank spaces
\t Matches only on a tab
\v Matches only on a vertical tab
\w Matches only on A to Z, a to z, 0 to 9, and _
\W Matches characters other than A to Z, a to z, 0 to 9, and _
\number Matches any positive number
\octal Matches any octal number
\xhex Matches any hexadecimal number (x is required)


It's really fun to mess with!

Actually jeep, I am guessing that you have code to split each move already. Can't you just apply the simple \{.*\} regexp to each move entry afterwards for parsing out the alias text?

[CrystyB]

Vin, the parsing-for-moves RegExp uses all the spaces it finds, i strongly suspect. (i don't know yet where does the comma come from.) The thing is: how to ignore spaces within curly brackets...

Ow, and thanks for the RegExp 101, but i guess i could get that from a manpage somewhere. I think i once or twice already looked at it, but it didn't stuck. It's just too much stuff to sink my teeth in at once. I'd rather just use "*" and "?", or do it myself. I know there aren't many (if any) arguments for what i'm saying, but i'm too lazy to study REs.

[CrystyB]

mg: oops, you do have a point, but it's not entirely correct. The board in Y is a triangle, which cannot be made similar to the Hex's rhombus.

Vin: i don't see how that (stick quotes around it, inside curly brackets) is any different better than the current (stick curly brackets around it)...

[Vinny]

lol.

true. I just looked to my eyes better that way


I guess I should wait for jeep to show us the regexp he's using currently (if he does) before making further suggestion.

[jeep]

Heh, today it's: #[\s,]+#

that is: preg_split ('#[\s,]+#', $text)

(or something very close...) I split it based on spaces or commas, THEN I break up each move into it's parts... (one of which is #{(.*)}#, to which I backreference to get the alias.)

-JEEP

[jeep]

OK so here is how I'm thinking the regexp might work:

invert the set of \S (non-white space) and {.*} and that's what I want. Now I just need to figure it out:

#[^\S({.*})]# didn't work, but I didn't really expect it to.

-JEEP

[jeep]

I'm annoyed at myself... the solution was relatively simple, once I changed my way of thinking:


Instead of splitting, match and then it's just;

[Lucky Wizard]

See the GLN thread... the PGN tags seem buggy, as the PGN notation no longer shows up in (for example) the PGN example in the GLN thread.

[jeep]

Huh, haven't touched that code in a while... so what's buggy other than the titles not showing?

-JEEP

EDIT: Found it. Let me know about anything else.

[CrystyB]

What's with this?? As i_h8_evil_stuff posted, it's sideways... How come??

[edit]But please don't remove that possibility. It would make for some interesting chess puzzles for the novices. [/edit]

[edit]Strangely, when replying to the thread, the board in the Review Topic iframe looks just like it's supposed to!!
And it's not just that one post. The board in the first post in that thread is affected too.

[update]Each second chessboard tag is switching colour placements. That's why in the Review Topic iframe, the board in the first post was affected.

[CrystyB]

fooling around with making the Chess tag promote one of my pawns, i tried f8-f8+Nf8 (since f8N was not valid -- i now understand it's supposed to be f8=N, but still, you might want to 'catch' this). This resulted in a total mess, with these messages output on the page:

[jeep]

So the bug is that the second board is reveresed? *sigh* I'll fix that. If you want to rotate the board, you'll have to use chessvariant tags, but that feature doesn't work as well as I'd like.

EDIT: I ported this from a stand alone app... I made the square color static...
