[Code] wrap length

[BeebMaster]

Is it possible to set the line length for wraparound when using "code" tags?

Lines longer than the message width are displayed with a horizontal scroll bar, and it would look a lot better if they wrapped at the same point as the right-hand margin in the normal message text.

e.g. the end of my post here where I posted a one-liner which doesn't wrap.

no, code tags in phpBB don't wrap. There might be an option to allow it, but I've never been on a board that does it

It is possible, but it requires hacking the theme. IIRC older versions of phpBB did this automatically, but recent versions try to look more pretty by adding scrollbars.

Basically in styles/prosilver/theme/content.css in the section defining ".codebox code {"
* remove "max-height: 200px;" if you want to remove vertical scrolling and make the codebox as tall as possible.
* add "white-space: break-spaces;" and it will turn off horizontal scrolling and will word-wrap

Of course all hacks like this make phpBB upgrades harder, and the admins of this forum don't want to do things that'll make life harder (which I totally agree with).

And with the "select all" option people can easily cut'n'paste into their editor of choice, which is what I do if I want to look at longer code segments.

You could make the line shorter:

Code: Select all

DIMosb 32:!osb=&1f001000:osb!4=0:osb!8=&200000:$(osb+11)="SYST":osb?15=13:A%=20:X%=osb MOD256:Y%=osb/256:CA.&FFF1

Code: Select all

DIMosb 32:!osb=&1f001000:osb!4=0:osb!8=&200000:$(osb+11)="SYST":osb?15=13:A%=20:X%=osb MOD256:Y%=osb/256:CA.&FFF1

smaller still if you didn't call the buffer the gratuitously long "osb".

DIMosb 32:!osb=&1f001000:osb!4=0:osb!8=&200000:$(osb+11)="SYST":osb?15=13:A%=20:X%=osb MOD256:Y%=osb/256:CA.&FFF1

smaller still if you didn't call the buffer the gratuitously long "osb".

and:

Code: Select all

osb!8=2^21

[BigEd]

Ah! I thought there'd be a shorter way to express that!

Edit: can we also do

Code: Select all

$(osb+11)="SYST"+CHR$13

Edit: do we need the MOD 256 here?

Code: Select all

X%=osb MOD256

[BeebMaster]

Well yes, but I still wanted the "short" version to be recognisable as a contraction of the program I posted in the same post.

Does this work I wonder...

"DIM X% 32" is a neat shortcut that I've seen jgh using.

Ooh, clever

78 characters if you don't mind the memory leak:

Code: Select all

DIMX%32:Y%=X%DIV256:!X%=&1000:X%!3=31:X%!7=0:$(X%+10)="SYST":A%=&14:CALL&FFF1

Having X% pointing to your control block is a useful technique as you can access it with X% indirections. I set up a global control block and initialise X%/Y% to point to it, and reinistialise X%/Y% at the start of any main loop if the program contains any calls that use X%/Y% themselves.

Eg:
10 REM > Demo
20 DIM ctrl% 31:X%=ctrl%:Y%=X%DIV256
30 blah blah
40 ON ERROR IF FNerr THEN PROCexit(ERR)
50 REPEAT:X%=ctrl%:Y%=X%DIV256
60 blah blah
70 UNTIL done:PROCexit(0)
80 :
90 DEFFNnetfs_op(A%,N%,A$):!X%=A%*256:X%?3=N%+LENA$:$(X%+N$)=A$:A%=&14:CALL&FFF1:ENDPROC
100 DEFPROCgbpb(A%,ch%,ad%,nm%,pt%):?X%=ch%:X%!1=ad%:X%!5=nm%:X%!9=pt%:CALL&FFD1:ENDPROC
110 DEFFNbyte(A%,X%,Y%)=((USR&FFF4)AND&FF00)DIV256
sorta thing.

I also program for A% and A$ to be "scratch" variables that can be used in any part of the program, knowing that if you call elsewhere they may have been trashed, so save having to save and restore them all the time.
