I need to extract a file name from complete path and I see it strange that I when I split the path, I need to iterate through the list to get the file name. Why can't I just get the value simply by calling myList(3) as in DotNet, instead of having to instantiate an iterator, then loop through the records.
Here is my code;
List strlist=new List(Types::String);
strlist = strSplit(CompletePath, #"\");
After doing this I should have a list of all the different parts.
Is there any simple form to read the list, like FileName = strlist[2]; instead of having to do the below;
iterator = new ListIterator(strlist);
while(iterator.more())
{
FileName = iterator.value();
if (_Value == "myFile")
{
_NotFound=boolean::false;
}
Here again, if at that very moment, I don't know the file name, how do I check?
Global::fileNameSplit(fileName)
returns a container [path, file name, extension]
Should be used over the .NET methods recommended by Matej.
Use System.IO.Path::GetFileName(CompletePath) or System.IO.Path::GetFileNameWithoutExtension.

I have been working on legacy application where i am using Aspose.Words.jdk15.jar to print the .doc file. I have a requirement where i am getting list of value then we have to loop & print it in the doc file.
And that value we are replacing in doc using range.replace() method . This doc already exists in my workspace where we have mapped the value like this
Component Name:$COMPONENT_NAME
Billing Effective Date:$EFFECTIVE_DATE
Billing End Date:$END_DATE
and the code which i have written to replace the value of doc. So, my requirement is I need this value multiple times in my doc as per size of list.
for(int i=0;i<details.size();i++)
{
doc.getRange().replace("$COMPONENT_NAME" , checkNull(details.get(i).getComponentName()) + “,”, false, false);
doc.getRange().replace("$EFFECTIVE_DATE" , checkNull(details.get(i).getBillEffectiveDate()) + “,”, false, false);
doc.getRange().replace("$END_DATE" , checkNull(details.get(i).getBillEndDate()) + “,”, false, false);
}
The best way to achieve what you need is using mail Merge feature.
https://docs.aspose.com/words/java/about-mail-merge/
But in this case you need to replace your placeholders with mergefields in your template.
If you cannot change the template, you can clone the the document for each item in your list, replace values in the cloned document and them merge documents together to get the final result. Code will look like the following:
// Open template
Document doc = new Document("C:\\Temp\\in.doc");
// Create document where result will be stored to.
// Simply clone the original template without children,
// In this case styles of the original document will be kept.
Document result = (Document)doc.deepClone(false);
for(int i=0; i<details.length; i++)
{
Document component = doc.deepClone();
component.getRange().replace("$COMPONENT_NAME", details[i].getComponentName());
component.getRange().replace("$EFFECTIVE_DATE", details[i].getBillEffectiveDate().toString());
component.getRange().replace("$END_DATE", details[i].getBillEndDate().toString());
// Append the result to the final document.
result.appendDocument(component, ImportFormatMode.USE_DESTINATION_STYLES);
}
result.save("C:\\Temp\\out.doc");
But I would preferer Mail Merge approach.
I'm currently using a not-very-Scala-like approach to parse large Unix mailbox files. I'm still learning the language and would like to challenge myself to find a better way, however, I do not believe I have a solid grasp on just what can be done with an Iterator and how to effectively use it.
I'm currently using org.apache.james.mime4j, and I use the org.apache.james.mime4j.mboxiterator.MboxIterator to get a java.util.Iterator from a file, as so:
// registers an implementation of a ContentHandler that
// allows me to construct an object representing an email
// using callbacks
val handler: ContentHandler = new MyHandler();
// creates a parser that parses a SINGLE email from a given InputStream
val parser: MimeStreamParser = new MimeStreamParser(configBuilder.build());
// register my handler
parser.setContentHandler(handler);
// Get a java.util.Iterator
val iterator = MboxIterator.fromFile(fileName).build();
// For each email, process it using above Handler
iterator.forEach(p => parser.parse(p.asInputStream(Charsets.UTF_8)))
From my understanding, the Scala Iterator is much more robust, and probably a lot more capable of handling something like this, especially because I won't always be able to fit the full file in memory.
I need to construct my own version of the MboxIterator. I dug through the source for MboxIterator and was able to find a good RegEx pattern to use to determine the beginning of individual email messages with, however, I'm drawing a blank from now on.
I created the RegEx like so:
val MESSAGE_START = Pattern.compile(FromLinePatterns.DEFAULT, Pattern.MULTILINE);
What I want to do (based on what I know so far):
Build a FileInputStream from an MBOX file.
Use Iterator.continually(stream.read()) to read through the stream
Use .takeWhile() to continue to read until the end of the stream
Chunk the Stream using something like MESSAGE_START.matcher(someString).find(), or use it to find the indexes the separate the message
Read the chunks created, or read the bits in between the indexes created
I feel like I should be able to use map(), find(), filter() and collect() to accomplish this, but I'm getting thrown off by the fact that they only give me Ints to work with.
How would I accomplish this?
EDIT:
After doing some more thinking on the subject, I thought of another way to describe what I think I need to do:
I need to keep reading from the stream until I get a string that matches my RegEx
Maybe group the previously read bytes?
Send it off to be processed somewhere
Remove it from the scope somehow so it doesn't get grouped the next time I run into a match
Continue to read the stream until I find the next match.
Profit???
EDIT 2:
I think I'm getting closer. Using a method like this gets me an iterator of iterators. However, there are two issues: 1. Is this a waste of memory? Does this mean everything gets read into memory? 2. I still need to figure out a way to split by the match, but still include it in the iterator returned.
def split[T](iter: Iterator[T])(breakOn: T => Boolean):
Iterator[Iterator[T]] =
new Iterator[Iterator[T]] {
def hasNext = iter.hasNext
def next = {
val cur = iter.takeWhile(!breakOn(_))
iter.dropWhile(breakOn)
cur
}
}.withFilter(l => l.nonEmpty)
If I understand correctly, you want to lazily chunk a large file delimited by a regex recognizable pattern.
You could try to return an Iterator for each request but the correct iterator management would not be trivial.
I'd be inclined to hide all file and iterator management from the client.
class MBox(filePath :String) {
private val file = io.Source.fromFile(filePath)
private val itr = file.getLines().buffered
private val header = "From .+ \\d{4}".r //adjust to taste
def next() :Option[String] =
if (itr.hasNext) {
val sb = new StringBuilder()
sb.append(itr.next() + "\n")
while (itr.hasNext && !header.matches(itr.head))
sb.append(itr.next() + "\n")
Some(sb.mkString)
} else {
file.close()
None
}
}
testing:
val mbox = new MBox("so.txt")
mbox.next()
//res0: Option[String] =
//Some(From MAILER-DAEMON Fri Jul 8 12:08:34 2011
//some text AAA
//some text BBB
//)
mbox.next()
//res1: Option[String] =
//Some(From MAILER-DAEMON Mon Jun 8 12:18:34 2012
//small text
//)
mbox.next()
//res2: Option[String] =
//Some(From MAILER-DAEMON Tue Jan 8 11:18:14 2013
//some text CCC
//some text DDD
//)
mbox.next() //res3: Option[String] = None
There is only one Iterator per open file and only the safe methods are invoked on it. The file text is realized (loaded) only on request and the client gets just what's requested, if available. Instead of all lines in one long String you could return each line as part of a collection, Seq[String], if that's more applicable.
UPDATE: This can be modified for easy iteration.
class MBox(filePath :String) extends Iterator[String] {
private val file = io.Source.fromFile(filePath)
private val itr = file.getLines().buffered
private val header = "From .+ \\d{4}".r //adjust to taste
def next() :String = {
val sb = new StringBuilder()
sb.append(itr.next() + "\n")
while (itr.hasNext && !header.matches(itr.head))
sb.append(itr.next() + "\n")
sb.mkString
}
def hasNext: Boolean =
if (itr.hasNext) true else {file.close(); false}
}
Now you can .foreach(), .map(), .flatMap(), etc. But you can also do dangerous things like .toList which will load the entire file.
Is there any way to parametise the Datasource for the 'source' field in the Template Builder?
We have a multisite setup. As part of this it would save a lot of time and irritation if we could point our Droptrees and Treelists point at the appropriate locations rather than common parents.
For instance:
Content
--Site1
--Data
--Site2
--Data
Instead of having to point our site at the root Content folder I want to point it at the individual data folders, so I want to do something like:
DataSource=/sitecore/content/$sitename/Data
I can't find any articles on this. Is it something that's possible?
Not by default, but you can use this technique to code your datasources:
http://newguid.net/sitecore/2013/coded-field-datasources-in-sitecore/
You could possibly use relative paths if it fits with the rest of your site structure. It could be as simple as:
./Data
But if the fields are on random items all over the tree, that might not be helpul.
Otherwise try looking at:
How to use sitecore query in datasource location? (dynamic datasouce)
You might want to look at using a Querable Datasource Location and plugging into the getRenderingDatasource pipeline.
It's really going to depend on your use cases. The thing I like about this solution is there is no need to create a whole bunch of controls which effectively do he same thing as the default Sitecore ones, and you don't have to individually code up each datasource you require - just set the query you need to get the data. You can also just set the datasource query in the __standard values for the templates.
This is very similar to Holger's suggestion, I just think this code is neater :)
Since Sitecore 7 requires VS 2012 and our company isn't going to upgrade any time soon I was forced to find a Sitecore 6 solution to this.
Drawing on this article and this one I came up with this solution.
public class SCWTreeList : TreeList
{
protected override void OnLoad(EventArgs e)
{
if (!String.IsNullOrEmpty(Source))
this.Source = SourceQuery.Resolve(SContext.ContentDatabase.Items[ItemID], Source);
base.OnLoad(e);
}
}
This creates a custom TreeList control and passes it's Source field through to a class to handle it. All that class needs to do is resolve anything you have in the Source field into a sitecore query path which can then be reassigned to the source field. This will then go on to be handled by Sitecore's own query engine.
So for our multi-site solution it enabled paths such as this:
{A588F1CE-3BB7-46FA-AFF1-3918E8925E09}/$sitename
To resolve to paths such as this:
/sitecore/medialibrary/Product Images/Site2
Our controls will then only show items for the correct site.
This is the method that handles resolving the GUIDs and tokens:
public static string Resolve(Item item, string query)
{
// Resolve tokens
if (query.Contains("$"))
{
MatchCollection matches = Regex.Matches(query, "\\$[a-z]+");
foreach (Match match in matches)
query = query.Replace(match.Value, ResolveToken(item, match.Value));
}
// Resolve GUIDs.
MatchCollection guidMatches = Regex.Matches(query, "^{[a-zA-Z0-9-]+}");
foreach (Match match in guidMatches)
{
Guid guid = Guid.Parse(match.Value);
Item queryItem = SContext.ContentDatabase.GetItem(new ID(guid));
if (item != null)
query = query.Replace(match.Value, queryItem.Paths.FullPath);
}
return query;
}
Token handling below, as you can see it requires that any item using the $siteref token is inside an Site Folder item that we created. That allows us to use a field which contains the name that all of our multi-site content folders must follow - Site Reference. As long at that naming convention is obeyed it allows us to reference folders within the media library or any other shared content within Sitecore.
static string ResolveToken(Item root, string token)
{
switch (token)
{
case "$siteref":
string sRef = string.Empty;
Item siteFolder = root.Axes.GetAncestors().First(x => x.TemplateID.Guid == TemplateKeys.CMS.SiteFolder);
if (siteFolder != null)
sRef = siteFolder.Fields["Site Reference"].Value;
return sRef;
}
throw new Exception("Token '" + token + "' is not recognised. Please disable wishful thinking and try again.");
}
So far this works for TreeLists, DropTrees and DropLists. It would be nice to get it working with DropLinks but this method does not seem to work.
This feels like scratching the surface, I'm sure there's a lot more you could do with this approach.
I want to place some helper functions in another file, since they will be overly reused. I took the Computer-Databse sample's listing file:
https://github.com/playframework/Play20/blob/master/samples/scala/computer-database/app/views/list.scala.html
I created a new file, called "listing.scala.html" under the app/views package, and moved the #link function from the original file to it. This new file looks like this:
#(currentSortBy: String, currentOrder: String, currentFilter: String)
#****************************************
* Helper generating navigation links *
****************************************#
#link(newPage:Int, newSortBy:String) = #{
var sortBy = currentSortBy
var order = currentOrder
if(newSortBy != null) {
sortBy = newSortBy
if(currentSortBy == newSortBy) {
if(currentOrder == "asc") {
order = "desc"
} else {
order = "asc"
}
} else {
order = "asc"
}
}
// Generate the link
routes.Application.listPerfil(newPage, sortBy, order, currentFilter)
}
So, on my original file, I replaced the #link call, with this one:
#title
And the problem is, when I try to compile I get this error:
value link is not a member of play.api.templates.Html
But according to the documentation (http://www.playframework.org/documentation/2.0.4/ScalaTemplateUseCases) it seems to be ok.
Any guess?
Play's templates aren't the best place for placing advanced conditions, most probably you'll get better flexibility by processing it in some controller (or other method) which will return you only required link
ie.:
#title
In your case proposed link(...) function of Application controller can also return a reverse-route.
Keep in mind that including other templates is best option for repeating blocks of HTML but sometimes it's hard to get specified string (mainly because of not trimmed spaces). As you can see there is also problem with calling nested functions. Most probably you can generate whole A tag in the listing.scala.html however using it isn't comfortable enough (IMHO).
I'm storing the page content in a database table. The page content also includes some CF variables (for example "...this vendor provides services to #VARIABLES.vendorLocale#").
VARIABLES.vendorLocal is set on the page based on a URL string.
Next a CFC is accessed to get the corresponding page text from the database.
And this is then output on the page: #qryPageContent.c_content#
But #VARIABLES.vendorLocale# is showing up as is, not as the actual variable. Is there anyway to get a "variable within a variable" to be output correctly?
This is on a CF9 server.
If you have a string i.e.
variables.vendorLocal = 'foo';
variables.saveMe = 'This is a string for supplier "#variables.vendorLocal#'"' ;
WriteOutput(variables.saveMe); // This is a string for locale "foo"
then coldfusion will attempt to parse that to insert whatever variable variables.vendorLocale is. To get around this, you can use a placeholder string that is not likely to be used elsewhere. Commonly you'll see [[NAME]] used for this purpose, so in this example
variables.saveMe = 'This is a string for supplier "[[VENDORLOCALE]]'"' ;
WriteOutput(variables.saveMe); // This is a string for supplier "[[VENDORLOCALE]]"
Now you've got that you can then later on replace it for your value
variables.vendorLocal = 'bar';
variables.loadedString = Replace(variables.saveMe,'[[VENDORLOCALE]]',variables.vendorLocal);
WriteOutput(variables.loadedString); // This is a string for locale "bar"
I hope this is of help
There are lots of reasons storing code itself in the database is a bad idea, but that's not your question, so I won't go into that. One way to accomplish what you want is to take the code you have stored as as string, write a temporary file, include that file in the page, then delete that temporary file. For instance, here's a little UDF that implements that concept:
<cfscript>
function dynamicInclude(cfmlcode){
var pathToInclude = createUUID() & ".cfm";
var pathToWrite = expandPath(pathToInclude);
fileWrite(pathToWrite,arguments.cfmlcode);
include pathToInclude;
fileDelete(pathToWrite);
}
language = "CFML";
somecfml = "This has some <b>#language#</b> in it";
writeOutput(dynamicInclude(somecfml));
</cfscript>
