| Anton 22-May-2006 [1177] | Yes, I shouldn't have assumed it was needed, but I gave them a Yahoo email anyway, so no drama. |
| Henrik 22-May-2006 [1178] | I'm sure they'll spend the rest of the day in agony that they didn't get your real email address. :-) |
| DideC 28-May-2006 [1179] | Question to HTML / CSS gurus I have to display Rebol code in an HTML page. I use <PRE> tags. Problem : whatever I use (Cell, Div, Pre) the wrap only occurs based on the window width, not the one I specified in the tag. So, how to force PRE text to wrap in a specific width ? |
| Geomol 28-May-2006 [1180x3] | Can it be solved using newlines? Like: <html> <head> <title>test</title> </head> <body> <pre>line 1 line 2 line 3 </pre> </body> </html> |
I don't think, you can force a wrap at a certain place. It's in the nature of HTML, as it's not wysiwyg. | |
From http://www.w3.org/TR/REC-html32 A few user agents support the WIDTH attribute. It provides a hint to the user agent of the required width in characters. The user agent can use this to select an appropriate font size or to indent the content appropriately. It's not the width of the line. | |
| DideC 28-May-2006 [1183] | I have tried Width, but it only shrinks the box, not the text inside (almoast on FF). Odd OMO. |
| Sunanda 28-May-2006 [1184] | <pre> literally means "as written" -- if there are no line breaks in the text, then there will be none on the page. *** Some lines in <pre> tags can be accidently enormously long, and need to be wrapped by hand. That's one reason REBOL.org offers you a user-setting for the point at which you want Mailing list messages to be forcibly wrapped: http://www.rebol.org/cgi-bin/cgiwrap/rebol/cpt-update-profile.r (See Appearance and settings / Point at which Mailing List Archive messages will start to wrap.) |
| [unknown: 9] 28-May-2006 [1185x2] | Dideir, yeah we ran into this recently in allowing people to escape code inside our Wiki. We allow Rebol, HTML, etc. At first it seems counter intuitive. But this is the way of HTML. Aside from the straight forward concept as Sunanda mentioned, if you are willing to process the code a little you can count the characters of the longest line, and scale the text to match the final output. A couple of points dropped on a font stil are readable, and many sentences still fit. Another is to encode the whole thing, in other words convert all the "<" for example to escape sequences. Now HTML will wrap everything automatically. |
Doh..."Didier" (I was tricked by looking at DideC). | |
| Sunanda 28-May-2006 [1187] | Your other alternative is to use the CSS overflow propery
eg
pre {overflow: auto} or overflow:scroll
The problem there is the inconsistency between browsers......
Good ones will add scroll bars only when needed. Common and bad ones
will add horizontal and vertical scroll bars at all times for every
pre box. It's ugly.
|
| BrianH 28-May-2006 [1188] | You can specify overflow-y and overflow-x separately if you prefer. |
| Chris 29-May-2006 [1189] | Bad ones = Internet Explorer. Even version 7 they haven't really figured out how most people use overflow: auto. Oneliners become unreadable. |
| [unknown: 9] 29-May-2006 [1190] | Yup. |
| DideC 29-May-2006 [1191x2] | I have tried "Overflow: auto" (I just had a look to makedoc anywhere result to see how it handles that), but fall on the I.E. inconsistency. |
So in conclusion, there is nothing simply usable in the browser(s), I have to cut the line "myself". F..k !! | |
| [unknown: 9] 29-May-2006 [1193x2] | Yup. |
In Qtask we autocut strings loner than X spaces so that webpages don't get screwed up. Slashdot does the same/ | |
| Alek_K 29-May-2006 [1195] | Well - there is property in CSS - 3 - but add this in style
pre {
white-space: pre-wrap; /* css-3 */
white-space: -moz-pre-wrap; /* Mozilla, since 1999 */
white-space: -pre-wrap; /* Opera 4-6 */
white-space: -o-pre-wrap; /* Opera 7 */
word-wrap: break-word; /* Internet Explorer 5.5+ */
}

| Allen 29-May-2006 [1196] | Another option is to show in a textarea and set the rows & columns |
| DideC 29-May-2006 [1197] | Alek : I will try that this evening. |
| Pekr 19-Jul-2006 [1198x2] | one question re CSS. I have small template, where I put two images one under the other. You can look at http://www.xidys.com/hanka. But I will need to cut some images, and that fact destroys aspect ratio for me :-) I would like to ask, if, in CSS, I can define image the way that it would not be scaled? My definition looks like: .photo img { width: 614px; height: 460px; } and in html: <div class="photo"><!--[obrazek 1]--><img src="obrazky/IMG_1361.JPG"/></div> |
I would like to have something like a face, where you insert image top-left corner, but it uses aspect effect, that once it reaches particular width or height, it is drawn to the face, but the other axis stays as-is, so the aspect radio is kept correct. With above definition, it simply scales image to defined width-height, and I have to properly cut image in xnview, counting pixel ratios .... and that is very boring job :-) | |
| Anton 19-Jul-2006 [1200] | http://rjohara.net/server/css-figures-captions/ |
| Pekr 19-Jul-2006 [1201] | how do I align text under the image? I mean - image itself has some white-border in it. The text looks far too left. I would like to align block of text following the image to the center, but not align center text itself ..... |
| Anton 19-Jul-2006 [1202x2] | The third image down has centred text on Firefox. |
(on my Firefox anyway) | |
| Alek_K 20-Jul-2006 [1204] | Pekr: 1. I don't know if i understand correctly, but if You give only one size (f.e. width), image will be scaled with aspect ratio to that size. You can set .photo size too of course (so it will not ruin Your layout) 2. Text under the image - I can't identify the problem. Can You give a link to it? |
| Pekr 20-Jul-2006 [1205x4] | Alek - thanks, I am already done with the problem. As for 2, I just wanted to center text under the image. But whole text block, not centered text itself - http://www.xidys.com/hanka/T-XI.html |
the text should be aligned to both sides, not centered. It is whole text block, which should be centered. http://www.xidys.com/hanka/F-VI-F-VII.html Can't express myself :-) | |

| Gabriele 22-Jul-2006 [1209] | Petr: give the text container a fixed width, then set both left and right margins to "auto". this should center it. |
| Alek_K 24-Jul-2006 [1210] | Maybe You thinks about justify? Add to "text" style: text-align: justify; |
| Josh 28-Jul-2006 [1211] | Not that it's incredibly important, but some the links on http://www.rebolforces.com/archive/index.html are quite broken |
| Allen 30-Jul-2006 [1212] | yes. sadly lost a lot stuff when the previous host shut down in the same week as my hard-drive died. I had to retrieve what I could via the wayback machine, and too few CD backups. |
| Pekr 3-Aug-2006 [1213x2] | a question - I have Windows app in cp-1250 encoding. Then I generate some html, which is server from Linux. When I look in Mozilla at the page source (http://www.jablunkovsko.cz), the browser displays some czech chars encoded, e.g. á. But when I save the page locally on my Windows machine, I get correct czech chars ... |
could there be some code-page problems? Should I better "url-encode" special czech alphabet chars into some "universal" format? | |
| Alek_K 3-Aug-2006 [1215] | I saved page locally, and have still ´ I suppose it's fault of WYSIWYG software made with english people in mind only (or not properly configured). No need to encoding special chars this way if You have characters in declared encoding (that's what <meta http-equiv="Content-Type" for). |
| Pekr 3-Aug-2006 [1216] | thanks, Alek! |
| Sunanda 11-Sep-2006 [1217] | Anyone else getting their logon pages nibbled by botnets? Here's some (failed) REBOL.org logons from yesterday. Format is attempted user-name (truncated to 12 characters) followed by IP address of the perp: hvrkme6mailr 203.113.13.4 wjn4r55ebayc 203.113.13.4 jsyqbrvebayc 220.124.170.169 mnpwtrugmail 220.70.88.162 orf9a3aaltav 220.77.210.71 lcfu7h2searc 217.10.190.36 djspeememail 211.170.204.237 zdgnhb9hotma 211.48.29.27 aown600micro 59.6.92.19 It seems sad that the level of intelligence of malicious bot writers is so low. I blame TV. |
| Ladislav 11-Sep-2006 [1218x2] | what would you say if the perpetrators "got through"? - I don't think intelligence is what is this about |
or, maybe it is about intelligence, but then it actually does not matter whether they succeed or not, their intelligence is of the same nature for me | |
| Anton 12-Sep-2006 [1220] | There are lots of desperate people out there. |
| Louis 19-Sep-2006 [1221] | Due to a very slow Internet connection, I need to make the FTP module of my website builder script more efficient so I don't send files unnecessarily. What I have in mind is: 1. Delete all the files in the website directory on my harddrive to eliminate all unused files. 2. Build the website to the website directory on my harddrive. 3. Download a list of the file names and creation dates from the website (all are in one directory). 4. Read the list of file names and creation dates from the directory on my harddrive (all are in the one directory mentioned in 2 above). 5. If a file is on the hard drive but not on the server, send it to the server. 6. If a file is on the server but not on the harddrive, delete the file on the server. 7. If a file on the harddrive is newer than a file on the server, send it to the server. Has anyone already done this? Am I forgetting anything? Any pointers on how to do this? |
| MikeL 19-Sep-2006 [1222x2] | Hi Louis, |
Sorry about the CRLF ..... you don't want to be checking the timestamps on the server with a slow connection. Just hold the last updated value locally and if it changes then transfer the file. Same for deleting ... else you spend all of your time checking on the server over a slow connection. You could check the timestamps or hash the local value ... then if the hash value of the source changes, transfer the updated version. There's some code to do some of this in build-sie.r http://www.rebol.org/cgi-bin/cgiwrap/rebol/view-script.r?script=build-site.r but it's a rebol-ish task. | |
| Louis 19-Sep-2006 [1224] | Thanks, Mike. I'm studying the build-site.r code now. |
| Henrik 19-Sep-2006 [1225] | if you are on an unreliable or slow connection, you might experience timeouts which will in turn cause network errors. I recently worked on a similar system and you have to basically wrap all code that access the internet in TRY and do a lot of error trapping and possibly some retrying to ensure that uploads and downloads of entire filesets are done correctly. The code in build-site.r will not do that, so you have to restart the upload if it fails. |
