I want to click on a link with variable text:
#variabletext = 'text' +#timestamp
But the link has a number like 01 # text010120121134. I just know text010120121134. Can someone help me click on the link with known text only.
If you only know part of the link's text, use a regex to match the text:
browser.link(:text => /text010120121134/).click
This would match the link:
<a>01 # text010120121134</a>
Since the text "01 # text010120121134" matches the regex pattern "/text010120121134/". Note that regexes are denoted by the '/'s.

I have a link by this text,
s= "http://xyz.com/Getid.ashx?JobID=250920&JobTitle=office+junior&seswitch=1&lid=801&AVSDM=2012-11-22+11%3a33%3a00"
I need to extract two information from this link
1)JobID which "250920"
2)JobTitle which is "office junior"
Is this possible by using gsub will I be able to get only those text from the link?
You can try .match with a regex:
result = s.match(/JobID\=(\d+).+JobTitle\=([a-zA-Z+0-9]+)\&/)
result[1] #JobID
result[2] #JobTile
I have an automated report tool (corp intranet) where the admins have a few text area boxes to enter some text for different parts of the email body.
What I'd like to do is parse the contents of the text area and wrap any hyperlinks found with link tags (so when the report goes out there are links instead of text urls).
Is ther a simple way to do something like this without figuring out a way of parsing the text to add link tags around a found (['http:','https:','ftp:] TO the first SPACE after)?
Thank You!
Ruby 1.87, Rails 2.3.5
Make a helper :
def make_urls(text)
urls = %r{(?:https?|ftp|mailto)://\S+}i
html_text = text.gsub urls, '\0'
html_text
end
on the view just call this function , you will get the expected output.
like :
irb(main):001:0> string = 'here is a link: http://google.com'
=> "here is a link: http://google.com"
irb(main):002:0> urls = %r{(?:https?|ftp|mailto)://\S+}i
=> /(?:https?|ftp|mailto):\/\/\S+/i
irb(main):003:0> html = string.gsub urls, '\0'
=> "here is a link: http://google.com"
There are many ways to accomplish your goal. One way would be to use Regex. If you have never heard of regex, this wikipedia entry should bring you up to speed.
For example:
content_string = "Blah ablal blabla lbal blah blaha http://www.google.com/ adsf dasd dadf dfasdf dadf sdfasdf dadf dfaksjdf kjdfasdf http://www.apple.com/ blah blah blah."
content_string.split(/\s+/).find_all { |u| u =~ /^https?:/ }
Which will return: ["http://www.google.com/", "http://www.apple.com/"]
Now, for the second half of the problem, you will use the array returned above to subsititue the text links for hyperlinks.
links = ["http://www.google.com/", "http://www.apple.com/"]
links.each do |l|
content_string.gsub!(l, "<a href='#{l}'>#{l}</a>")
end
content_string will now be updated to contain HTML hyperlinks for all http/https URLs.
As I mentioned earlier, there are numerous ways to tackle this problem - to find the URLs you could also do something like:
require 'uri'
URI.extract(content_string, ['http', 'https'])
I hope this helps you.
I'm writing a site with a custom tweet button that uses the www.twitter.com/share function, however the problem I am having is including hash '#' characters within the tweet text.
For example:
http://www.twitter.com/share?url=www.example.com&text=I+am+eating+#branstonpickel+right+now
The tweet text comes out as 'I am eating' and omits the hash and everything after.
I had a quick look on the Twitter forums and learnt the hash '#' character cannot be part of the share url. On https://dev.twitter.com/discussions/512#comment-877 it was said that:
Hashes are special characters in the URL (they identify document fragments) so they, and anything following, does not get sent the server.
and
you need to URLEncode it, so use %23
When I tried the 2nd point in my test link:
www.twitter.com/share?url=www.example.com&text=I+am+eating+%23branstonpickel+right+now
The tweet text came out as 'I am eating %23branstonpickel right now' literally including %23 instead of converting it to a hash.
Sorry for the waffely question, but does anyone know what it is I'm doing wrong?
Any feedback would be greatly appreciated :)
It looks like this is the basic setup:
https://twitter.com/intent/tweet?
url=<url to tweet>
text=<text to tweet>
hashtags=<comma separated list of hashtags, with no # on them>
This would pre-built a tweet of: <text> <url> <hashtags>
The above example would be:
https://twitter.com/intent/tweet?url=http://www.example.com&text=I+am+eating+branston+pickel+right+now&hashtags=bransonpickel,pickles
There used to be a bug with the hashtags parameter... it only showed the first n-1 hashtags. Currently this is fixed.
you can use %23 instead of hash (#) in url eg
http://www.twitter.com/share?url=www.example.com&text=I+am+eating+%23branston+%23pickel+right+now
I may be wrong but i think the hashtag has to be passed as a separate variable that will appear at the end of your tweet ie:
http://www.twitter.com/share?url=www.example.com&text=I+am+eating+branston+pickel+right+now&hashtag=bransonpickel
will result in "I am eating branston pickel right now #branstonpickle"
On a separate note, I think pickel should be pickle!

use encodeURIComponent to encode the url
If you're using PHP, you can use the following:
<?php echo 'http://www.twitter.com/share?' . http_build_query(array(
'url' => 'http://www.example.com',
'text' => 'I am eating #branstonpickel right now'
)); ?>
This will do all the URL encoding for you, and it's easy to read.
For more information on the http_build_query, see the PHP manual:
http://us2.php.net/http_build_query
For url with line jump, # , # and special unicode in it, the following works :
var lineJump = encodeURI(String.fromCharCode(10)),
hash = "%23", arobase="%40",
tweetText = 'https://twitter.com/intent/tweet?text=Le signe chinois '+hans+' '+item.pinyin+': '+item.definition.replace(";",",")+'.'
+lineJump+'Merci '+arobase+'Inalco_Officiel '+arobase+'CRIparis ❤️🇨🇳 '
+lineJump+hash+'Chinois '+hash+'MOOC'
+lineJump+'https://hanzi.cri-paris.org/',
tweetTxtUrlEncoded = tweetText+ "" +encodeURIComponent('#'+lesson+encodeURIComponent(hans));
urlencode
https://twitter.com/intent/tweet?text=<?= urlencode("I am eating #branstonpickel right now"); ?>"
You can just use this code and modify it
20% means space
23% means hashtag
In JS you can easily encode the special characters using encoreURIComponent.
(Warning: don't use encodeURI as "#" and "#" are not escaped.)
Here's an example with mention and hashtag:
const text = "Hello #world ! Go follow #StackOverflow";
const tweetUrl = `https://twitter.com/intent/tweet?text=${ encodeURIComponent(text) }`;
I'm implementing a search in my website, and would like to support searching for exact phrases. I want to end up with an array of terms to search for; here are some examples:
"foobar \"your mom\" bar foo" => ["foobar", "your mom", "bar", "foo"]
"ruby rails'test course''test lesson'asdf" => ["ruby", "rails", "test course", "test lesson", "asdf"]
Notice that there doesn't necessarily have to be a space before or after the quotes.
I'm not well versed in regular expressions, and it seems unnecessary to try to split it repeatedly on single characters. Can anybody help me out? Thanks.'
You want to use this regular expression (see on rubular.com):
/"[^"]*"|'[^']*'|[^"'\s]+/
This regex matches the tokens instead of the delimiters, so you'd want to use scan instead of split.
The […] construct is called a character class. [^"] is "anything but the double quote".
There are essentially 3 alternates:
"[^"]*" - double quoted token (may include spaces and single quotes)
'[^']*' - single quoted token (may include spaces and double quotes)
[^"'\s]+ - a token consisting of one or more of anything but quotes and whitespaces

Snippet
Here's a Ruby implementation:
s = %_foobar "your mom"bar'test course''test lesson'asdf_
puts s
puts s.scan(/"[^"]*"|'[^']*'|[^"'\s]+/)
The above prints (as seen on ideone.com):
foobar "your mom"bar'test course''test lesson'asdf
foobar
"your mom"
bar
'test course'
'test lesson'

Which style of Ruby string quoting do you favour?
Quick background: I have a string which contains references to other pages. The pages are linked to using the format: "#12". A hash followed by the ID of the page.
Say I have the following string:
str = 'This string links to the pages #12 and #125'
I already know the IDs of the pages that need linking:
page_ids = str.scan(/#(\d*)/).flatten
=> [12, 125]
How can I loop through the page ids and link the #12 and #125 to their respective pages? The problem I've run into is if I do the following (in rails):
page_ids.each do |id|
str = str.gsub(/##{id}/, link_to("##{id}", page_path(id))
end
This works fine for #12 but it links the "12" part of #125 to the page with ID of 12.
Any help would be awesome.
Instead of extracting the ids first and then replacing them, you can simply find and replace them in one go:
str = str.gsub(/#(\d*)/) { link_to("##{$1}", page_path($1)) }
Even if you can't leave out the extraction step because you need the ids somewhere else as well, this should be much faster, since it doesn't have to go through the entire string for each id.
PS: If str isn't referred to from anywhere else, you can use str.gsub! instead of str = str.gsub
if your indexes always end at word boundaries, you can match that:
page_ids.each do |id|
str = str.gsub(/##{id}\b/, link_to("##{id}", page_path(id))
end
you only need to add the word boundary symbol \b on the search pattern, it is not necessary for the replacement pattern.
