In smalltalk, How can I add to string a link
example :
I have a string str = "trial string"
I want to add another string to it but when I click on it I go to some destination
and str will appear like
trial string and SomeLocation
If you are using Seaside you can use the following piece of code when your component will be rendered.
renderContentOn: html
html anchor
url: 'http://www.seaside.st';
with: 'Visit the Seaside'.
In any programming language, strings are just sequences of characters. Wether or not a hyperlink (in html markup language) is shown as a clickable link, as it is shown in a web browser, depends on how the string is interpreted by the editor/viewer that shows it.
If you want to show hyperlinks in Smalltalk code, I don't know of any Smalltalk IDE that has support for that. But I would not be surprised if there is some project out there that supports doing that.

I am creating a template in Wikipedia to link articles to an external website which is a book archive called fadedpage.com. I am generating a url to link to a specific author page. Part of the url is the author's name which contains one or more spaces. For example, the url for the author "Ian Fleming" is: http://fadedpage.com/csearch.php?author=Fleming, Ian. My template call structure is {{FadedPage|id=Fleming, Ian|name=Ian Fleming|author=yes}}.
For my template I am replicating an existing template which uses a script coded in lua to parse the template arguments. I have been able to generate all of the url except for the space character between the last and first name.
I could code the template call as: {{FadedPage|id=Fleming,%20Ian|name=Ian Fleming|author=yes}} which works OK but I would rather have the call format as it looks on the fadedpage website, ie. with the embedded space. So I need a way in lua to find the space character within the string and substitute it for the string "%20". So far I haven't figured out how to do it. Any help would be appreciated.
I am making a website for my friend
https://photos4humanity.herokuapp.com/
I'm thinking to pull the post from its facebook page and display it on the website so he doesnt have to duplicate content for both.
Each facebook post has both english and chinese in it. like here :
https://www.facebook.com/photosforhumanity/
I would like to auto detect the language from the json file I get from facebook. Then detect which is in English and which is in Chinese then only display the right language according to internatioanlize from rails.
Is there a smart way to do this?
You could use Regex to detect if the string has any English characters or not:
isEnglish = myString.match(/[a-zA-Z]/)
or
isEnglish = myString =~ /[a-zA-Z]/
I haven't tested either of these and I don't know how your json file is organized, but this should work for a singular string.
Edit:
To pull the English characters out of the string, you can use the slice! method:
englishString = myString.slice!(/[a-zA-Z]/)
After doing that, myString should only contain non-English characters and englishString should contain only English characters.
I am just starting a very basic program in Grails (never used it before, but it seems to be very useful).
What I have so far is:
in X.groovy,
a String named parameters, with constraint of maximum length 50000 and a couple other strings and dates, etc.
in XController.groovy,
static scaffold = X;
It displays the scaffold UI (very handy!), and I can add parameter strings and the other objects associated with it.
My problem is that the parameters string is a long string with formatting that is pasted in by the user. When it is displayed on the browser, however, it does not retain any carriage returns.
What is the best way to go about this? I'm a very beginner at Grails and still have lots and lots of learning to do on this account. Thanks.
The problem is that the string is being displayed using HTML which doesn't parse \n into a new line by default. You need to wrap the text in <pre> (see: http://www.w3schools.com/tags/tag_pre.asp) or replace the \n with <br/> tags to display it correctly to the user.
Is there a way to take a text label and an URL and use Applescript add them to the Mac clipboard such that rich-text apps see the data as a URL and make linked anchor text when pasting in the data.
I have untitled reference URLs (generated via code) that need to have a 'screen' title (anchor text). I can create the URL and anchor text. But, how do I combine them so that the Mac clipboard treats the data as a URL? I tried:
set the clipboard to "" & theAnchor & ""
..but when using this data from other apps I get the HTML string and not a link with the anchor text as the visible screen text.
StandardAdditions has 'URL' and 'web page' classes but I can't see how to apply them. This compiles but fails when run:
set myURL to theURI as URL
set myLinkAnchor to theAnchor as text
set linkURL to {URL: myURL, name: myLinkAnchor} as web page
AppleScript does support putting hex encoded HTML into the clipboard:
set the clipboard to «data HTML3c6120687265663d22687474703a2f2f7777772e69727261646961746564736f6674776172652e636f6d22207461726765743d225f626c616e6b223e4972726164696174656420536f6674776172653c2f613e»
It's pretty round-about, but here's how to do what you want:
set theURI to "http://www.irradiatedsoftware.com"
set theAnchor to "Irradiated Software"
set the clipboard to "" & theAnchor & ""
set theHEX to do shell script "pbpaste | hexdump -ve '1/1 \"%.2x\"'"
if theHEX is "" then
beep
else
run script "set the clipboard to «data HTML" & theHEX & "»"
end if
YMMV. I tried pasting this into Word 2011 and it worked fine. I couldn't get Pages to take take the paste. Also, I tried pasting into a new email message (Mail.app), and the link is fine, but you can't click on it. However, the recipient can click on the link.
You can't assume that all applications accept HTMLand convert it automatically into a clickable string. Your ability to do this depends on how the target application handles rich text. Some may use Cocoa's built-in rich text area classes while others may have their own completely custom text areas, each handling URLs their own way. You can look in the target application's Dictionary to see if it allows you to create URLs in an identifiable way.
My website is XHTML Transitional compliant except for one thing: the & (ampersand) in the URL are written as it is, instead of &
That is, all the URLs in my pages are usually like this:
Foo
But XHTML validator generates this error:
cannot generate system identifier for general entity "y"
... and it wants the URL to be written like this:
Foo
The problem is that Internet Explorer and Firefox don't handle the URL correctly and ignore the y parameter. How can I make this link work and validate correctly?
It seems to me that it is impossible to write XHTML pages if the browsers don't work with strict encoded XHTML URLs.
Do you want to see in action? See the difference between these two links (copy and paste them as they are):
http://stackoverflow.com/search?q=ff&sort=newest
and
http://stackoverflow.com/search?q=ff&sort=newest
I have just tried this. What you attempted to do is correct. In HTML if you are writing a link the & characters should be encoded as & You would only encode the & as %26 if you wanted a parameter value to contain an ampersand. I just wrote a simple HTML page that contained a link: Click me
and it worked fine: default2.aspx received the parameters intended and the source passed validation.
The encoding of & as & is required in HTML, not in the link. When the browser sees the & in the HTML source for a link it will interpret it as an ampersand and the link target will be as intended. If you paste a URL into your browser address bar it does not expect it to be HTML and does not try to interpret any HTML encoding that it may contain. This is why your example links that you suggest we should copy/paste into a browser don't work and why we wouldn't expect them to work.
If you post a bit more of your actual code we might be able to see what you have done wrong, but you appear to be heading the right direction by using & in your anchor tags.
It was my fault: the hyperlink control already encoded &, so my URL http://foo?x=1&y=2 was encoded to http://foo?x=1&y=2
Normally the & inside the URL is correctly handled by browsers, as you stated.
You could use & instead of & in your URL within your page.
That should allow it to be validated as strict XHTML...
Foo
Note, if used by an ASP.NET Request.QueryString function, the query string doesn't use XML encoding; it uses URL encoding:
/mypath/mypage?b=%26stuff
So you need to provide a function translating '&' into %26.
Note: in that case, Server.URLEncode(”neetu & geetu”), which would produce neetu+%26+geetu, is not what you want, since you need to translate & into %26, not just '&'. You must add a replace() call applied to URLEncode result, in order to replace '%26amp;' by '%26'.
To be even more thorough: use &, a numeric character reference.
Because & is a character entity reference:
Character entity references are defined in the markup language
definition. This means, for example, that for HTML only a specific
range of characters (defined by the HTML specification) can be
represented as character entity references (and that includes only a
small subset of the Unicode range).
That's coming from the wise people at W3C (read this for more).
Of course, this is not a very big deal, but the suggestion of W3C is that the numeric one will be valid and useable everywhere and always, while the named one is 'fine' for HTML but nothing more.
The problem is worse than you think - try it in Safari. & gets converted to & and the hash ends the URL.
The correct answer is to not output XHTML - there's no reason that justifies spending more time on development and alienating Mac users.
