I have a string named MESSAGE and it varies depending on what people say.
Is there a way I can make MESSAGE replace the contents of a string inside of a string?
For example, if MESSAGE is equal to "Hey guys [rainbow]look at my awesome rainbow text[/rainbow] isn't it cool?" then how do I only replace the "[rainbow]look at my awesome rainbow text[/rainbow]" part by getting rid of "[rainbow]" and "[/rainbow]" and replacing "look at my awesome rainbow text" with a string called RAINBOWTEXT?
The reason I need this is because I would like users in my Flash-based chat to be able to make rainbow text, but the method I use needs to do this client-side. I did have a PHP version that would submit the text into the database, but it would cut the message off due to the large amount of data. Each character got a <font color="#123456"> and a </font> on either side of it, so messages were super long.
If I can replace the inside part of what is specified by [rainbow] and [/rainbow], I can have each person's client replace the message once it gets it. In the database, it will have "Hey guys [rainbow]look at my awesome rainbow text[/rainbow] isn't it cool?" but in chat it will have "Hey guys look at my awesome rainbow text isn't it cool?" with the actual text rainbowfied.
This sounds like a job for a regular expression and the replace() method. Have a dig around for expressions which will find and replace the contents of HTML tags and you should be able to adapt what you find to suit your requirements. Examples for JavaScript should also be valid as ActionScript and JavaScript both adhere to the ECMAScript standard for regular expressions.
Once you've found something, you can play around with it with this handy tool for testing ActionScript 3.0 regular expressions.

I'm working on a Salesforce coding issue. Let me preface this by saying I'm not a developer or Salesforce expert.
What language is this?
Data Type FormulaThis formula references multiple objects
IF (Fulfillment_Submission_Form_URL__c <> "" && CONTAINS(Fulfillment_Submission_Form_URL__c, "qualtrics"),
Fulfillment_Submission_Form_URL__c &
(IF (CONTAINS(Fulfillment_Submission_Form_URL__c,"?SID="), "&", "?")) &
(IF (CONTAINS(TEXT(Type__c), "Site Visit"),
"ContactId="&Statement_of_Work__r.Contractor_Contact__c&
"&CoachType="&SUBSTITUTE(Statement_of_Work__r.Work_Type__r.Name," ","%20")&
"&CoachName="&SUBSTITUTE(Statement_of_Work__r.Contractor_Name__c," ","%20")&
"&InitPartId="&Initiative_Participation__r.Id&
"&InstitutionName="&substitute(substitute(SUBSTITUTE(Institution_Name__c," ","%20"),")",""),"(","")&
"&AccountId="&Initiative_Participation__r.Participating_Institution__r.Id&

Essentially it's pulling a link from another product we've integrated it with. We then take the basic link and reformat it to add parameters.
The problem is when it pulls in some parameters (ex: CoachName) the Coach entered their name in strange formats like: John (Coach) Doe.
So when the script outputs a URL that includes parameters it breaks at the &CoachName=John%20(Coach)% portion of the URL. Any easy way to work around this by modifying the script? Unfortunately we DO need that (Coach) identifier because the system we push to grabs that as well.
It's formula syntax, I'd compare it to Excel-like formulas. There's self-paced training if you don't want to read documentation. And as it's not exactly code-related you may have more luck on dedicated site, https://salesforce.stackexchange.com/. More admins lurk there.
So you do want that "(Coach)" to go through but it breaks the link? Looks like ( is a special character. It's not technically wrong to have unescaped parentheses, if it breaks that other site you might want to contact them and get their act together. RFC doesn't force us to encode them but looks like you'll have to to solve it at least in the short term: https://webmasters.stackexchange.com/questions/78110/is-it-bad-to-use-parentheses-in-a-url
Instead of poor man's encoding (SUBSTITUTE(Statement_of_Work__r.Contractor_Name__c," ","%20") try using proper URLENCODE(Statement_of_Work__r.Contractor_Name__c).
Or there's bit more "pro" function called URLFOR but the documentation doesn't make it very clear how powerful the 3rd parameter is with the braces [key1 = value1, key2 = value2] syntax. Basically just pass the parameters and let SF worry about encoding special characters etc.
Read my answer https://salesforce.stackexchange.com/a/46445/799 and there are some examples on the net like https://support.docusign.com/s/articles/DFS-URL-buttons-for-Lightning-basic-setup-limitations?language=en_US&rsc_301
There is a webpage parser, which takes a page contains several tags, in a certain structure, where divs are badly nested. I need to extract a certain div element, and copy it and all its content to a new html file.
Since I am new to lua, I may need basic clarification for things might seem simple.
Thanks,
The ease of extraction of data is going to largely depend on the page itself. If the page uses the exact same tag information throughout its entirety, it'll be much more difficult to extract than it would if it has named tags.
If you're able to find a version of the page that returns json format, then you're that much better off. Here's a snippet of code on something I wrote to grab definitions from a webpage that did not have json format:
local actualword, definition = string.match(wayup,"<html.-<td class='word'>%c(.-)%c</td>.-<div class=\"definition\">(.-)</div>")
Essentially, this code searched down the page until it found the class "word", and took the word after it (%c is the pattern for control characters). It continued on to "definition" and captured that, as well.
As you can see, it's a bit convoluted, but I had the luck of having specifically named tags for what I wanted.
This is edited to fit your comment. As a side note that I should have mentioned before, if you're familiar with regular expressions, you can use its model to capture what you need. In this case, it's capturing the string in its totality:
local data = string.match(page, "(<div id=\"aa\"><div>.-</div>.-</div>)")
It's rarely the fault of the language, but rather the webpage itself, that makes it hard to data mine anything. Since webpages could literally have hundreds of lines of code, it's hard to pinpoint exactly what you want without coming across garbage information. It's why I prefer a simplified result such as json, since Lua has a json module that can encode/decode and you can get your precise information.
My Rails app processes incoming emails by splitting them into multiple lines. This is what I currently use on the plain text version of the body: lines = email.body.split("\n")
This works well unless the sentences are longer than ~74 characters as most email clients will automatically add a line break per RFC 2822.
Example email: https://gist.github.com/marckohlbrugge/39c17b928eb17d330d63
Looking at the plain text part there seems to be no way to discern between a line break added by the user versus the email client. You could ignore any line break happening at the 75th position, but I think there might be a chance of false positives. (I could be wrong.)
The HTML part has all the information we need, but I'm not sure about a universal way to process this. Is replacing every div and br with a newline and then stripping al other HTML elements enough? What about all the other block-element tags? What about inline elements styled as block-elements? What if an email doesn't have an HTML part?
I did find some interesting code examples in Convert HTML to plain text (with inclusion of s), but replacing a list of html tags with newlines doesn't seem like a complete (exhaustive) solution.
Is it worth looking at something like this mail library as they've probably already thought about the edge cases? ;)
I need to translate a website to a couple languages, and I've already read how to do it:
Mark strings for translation
Generate messages file
Translate messages file
The problem is, if I use whole sentences as the message ids, in english, for example, then if later I decide to modify the text, I'll have to change it in the code and on each message file . Or I could just change the english translation, but then my english message file will look weird, with translations from english to english which do not match.
Example:
Original: "I don't know what to do."
Translation: "I'm not sure what to do."
An alternative is to use unique message ids such as:
Original: "INDECISION_MESSAGE"
Translation: "I'm not sure what to do."
The advantage is that I can change translations without changing the id and things will still be consistent. But then there is no easy way for a translator to know what the message should be like as there is no context except by looking at the code.
What would you use?
In PHP people normally use the first approach you mentioned. In ASP.NET the second.
I think it's more of a personal taste and a matter of the framework that you use.
Personally I prefer the second option. Since you normally already have the ID/translation pair somewhere in a list, the translator can just take that list to translate.
What framework do you use?
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.
