I have html and javascript that grabs a file and parses it and places chunks of the file in a textbox. However, the file has ANSI codes for colors. I want the textbox to display these colors as well. I have found ANSI4J but I don't know how to incorporate it into my code. There is a readme file and it posts the following:
var palette = new XtermPalette256();
AttributeConfig config = new DefaultTextAttributeConfig.Builder()
.defaultForegroundColor(0x000000)
.defaultBackgroundColor(0xffffff)
.fontFamilies(List.of("Arial", "'Times New Roman', Times, serif"))
.extraColorsEnabled(true)
.palette16(palette)
.palette256(palette)
.build();
//Now we need context that will keep attributes.
AttributeContext context = new DefaultAttributeContext(List.of(config));
//Now we create a function processor.
var processor = new DefaultCssFunctionProcessor.Builder()
.resolvers(new DefaultTextAttributeResolver())
.generators(new JavaFxCssGenerator())
.build();
...
//To generate CSS declarations we need to process function fragments. Currently only SGR functions are supported
Fragment fragment = ... ;
if (fragment.getType() == FragmentType.FUNCTION) {
FunctionFragment functionFragment = (FunctionFragment) fragment;
if (functionFragment.getFunction() == ControlSequenceFunction.SGR_SELECT_GRAPHIC_RENDITION) {
List<String> declarations = processor.process(functionFragment, context);
var style = String.join(";", declarations);
...
}
}
but I don't know what to do with this.
Any help would be appreciated.

I'm sorry this question header is not 100% correct. Because of that, I'll explain my scenario here.
I created a function to merge 4 data sets into one return format. Because that's the format front-end side needed. So this is working fine now.
public ReturnFormat makeThribleLineChart(List<NameCountModel> totalCount, List<NameCountModel>,p1Count, List<NameCountModel> p2Count, List<NameCountModel> average) {
ReturnFormat returnFormat = new ReturnFormat(null,null);
try {
String[] totalData = new String[totalCount.size()];
String[] p1Data = new String[p1Count.size()];
String[] p2Data = new String[p2Count.size()];
String[] averageData = new String[p2Count.size()];
String[] lableList = new String[totalCount.size()];
for (int x = 0; x < totalCount.size(); x++) {
totalData[x] = totalCount.get(x).getCount();
p1Data[x] = p1Count.get(x).getCount();
p2Data[x] = p2Count.get(x).getCount();
averageData[x] = average.get(x).getCount();
lableList[x] = totalCount.get(x).getName();
}
FormatHelper<String[]> totalFormatHelper= new FormatHelper<String[]>();
totalFormatHelper.setData(totalData);
totalFormatHelper.setType("line");
totalFormatHelper.setLabel("Uudet");
totalFormatHelper.setyAxisID("y-axis-1");
FormatHelper<String[]> p1FormatHelper= new FormatHelper<String[]>();
p1FormatHelper.setData(p1Data);
p1FormatHelper.setType("line");
p1FormatHelper.setLabel("P1 päivystykseen heti");
FormatHelper<String[]> p2FormatHelper= new FormatHelper<String[]>();
p2FormatHelper.setData(p2Data);
p2FormatHelper.setType("line");
p2FormatHelper.setLabel("P2 päivystykseen muttei yöllä");
FormatHelper<String[]> averageFormatHelper= new FormatHelper<String[]>();
averageFormatHelper.setData(averageData);
averageFormatHelper.setType("line");
averageFormatHelper.setLabel("Jonotusaika keskiarvo");
averageFormatHelper.setyAxisID("y-axis-2");
List<FormatHelper<String[]>> formatHelpObj = new ArrayList<FormatHelper<String[]>>();
formatHelpObj.add(totalFormatHelper);
formatHelpObj.add(p1FormatHelper);
formatHelpObj.add(p2FormatHelper);
formatHelpObj.add(averageFormatHelper);
returnFormat.setData(formatHelpObj);
returnFormat.setLabels(lableList);
returnFormat.setMessage(Messages.Success);
returnFormat.setStatus(ReturnFormat.Status.SUCCESS);
} catch (Exception e) {
returnFormat.setData(null);
returnFormat.setMessage(Messages.InternalServerError);
returnFormat.setStatus(ReturnFormat.Status.ERROR);
}
return returnFormat;
}
so, as you can see here, all the formatting is hardcoded. So my question is how to automate this code for list count. Let's assume next time I have to create chart formatting for five datasets. So I have to create another function to it. That's the thing I want to reduce. So I hope you can understand my question.
Thank you.
You're trying to solve the more general problem of composing a result object (in this case ReturnFormat) based on dynamic information. In addition, there's some metadata being setup along with each dataset - the type, label, etc. In the example that you've posted, you've hardcoded the relationship between a dataset and this metadata, but you'd need some way to establish this relationship for data dynamically if you have a variable number of parameters here.
Therefore, you have a couple of options:
Make makeThribleLineChart a varargs method to accept a variable number of parameters representing your data. Now you have the problem of associating metadata with your parameters - best option is probably to wrap the data and metadata together in some new object that is provided as each param of makeThribleLineChart.
So you'll end up with a signature that looks a bit like ReturnFormat makeThribleLineChart(DataMetadataWrapper... allDatasets), where DataMetadataWrapper contains everything required to build one FormatHelper instance.
Use a builder pattern, similar to the collection builders in guava, for example something like so:
class ThribbleLineChartBuilder {
List<FormatHelper<String[]>> formatHelpObj = new ArrayList<>();
ThribbleLineChartBuilder addDataSet(String describeType, String label, String yAxisId, List<NameCountModel> data) {
String[] dataArray = ... ; // build your array of data
FormatHelper<String[]> formatHelper = new FormatHelper<String[]>();
formatHelper.setData(dataArray);
formatHelper.setType(describeType);
... // set any other parameters that the FormatHelper requires here
formatHelpObj.add(formatHelper);
return this;
}
ReturnFormat build() {
ReturnFormat returnFormat = new ReturnFormat(null, null);
returnFormat.setData(this.formatHelpObj);
... // setup any other fields you need in ReturnFormat
return returnFormat;
}
}
// usage:
new ThribbleLineChartBuilder()
.addDataSet("line", "Uudet", "y-axis-1", totalCount)
.addDataSet("line", "P1 päivystykseen heti", null, p1Count)
... // setup your other data sources
.build()
I have .docx file, containing mailMerge fields.
I want to extract all field names to List.
I saw some examples of dox4J, how to replace these fields with mapped value, but I DO NOT want to replace them, I need to read them only.
Is there a semy easy way to do that using docx4J?
Have a look at https://github.com/plutext/docx4j/blob/master/src/samples/docx4j/org/docx4j/samples/FieldsDiagnostics.java
You can also look at the code in MailMerger:
// find fields
ComplexFieldLocator fl = new ComplexFieldLocator();
new TraversalUtil(shellClone, fl);
// canonicalise and setup fieldRefs
List<FieldRef> fieldRefs = new ArrayList<FieldRef>();
canonicaliseStarts(fl, fieldRefs);
// Populate
for (FieldRef fr : fieldRefs) {
if ( fr.getFldName().equals("MERGEFIELD") ) {
String instr = extractInstr(fr.getInstructions() );
String datafieldName = getDatafieldNameFromInstr(instr);
I am using open graph library to fetch the metadata from url.
I am getting the title and description from url link which follow og tag rules. How to get metadata from url link which don't follow og tag.
my simple code :
OpenGraph data = new OpenGraph(url, true);
response.setDescription(data.getContent("description"));
response.setMetaDataImage(data.getContent("image"));
response.setTitle(data.getContent("title"));
response.setMetaDataUrl(data.getContent("url"));
Data fetch is null.
I think you're talking about this library. If so, the boolean in the constructor serves the purpose:
public OpenGraph(String url, boolean ignoreSpecErrors) {
...
}
The way I use this library to fetch, for example, images is as follows:
OpenGraph og = new OpenGraph(url, true);
MetaElement[] imageElements = og.getProperties("image");
Perhaps you are just using the wrong getter? If the page has og tags, this snippet should work!
I had similar issues with opengraph-java (ie. getting null response).
I tried the example in the docs, but the response was null
OpenGraph movie = new OpenGraph("http://www.rottentomatoes.com/m/back_to_the_future/", true);
System.out.println("movie = " + movie)); // movie = null
Trying the false option for ignoreSpecErrors throws an exception java.lang.Exception: Does not conform to Open Graph protocol
So I made a library called ogmapper that's a little more flexible.
DefaultOgMapper ogMapper = new JsoupOgMapperFactory().build();
OgTags ogTags = ogMapper.process(new URL("http://www.rottentomatoes.com/m/back_to_the_future/"));
System.out.println("title = " + ogTags.getTitle()); // title = Back to the Future (1985)
Hopefully this is helpful!
I am using Edraw Office Viewer component to open & edit the file. I want to save my file to my destination point so I am using JavaScript to save the file. But I am stuck at a point. I am showing my code below to save document using JavaScript.
function f_saveDocument(){
if(document.OA1.IsOpened)
{
var saveAsFileName = document.getElementById('hdnFileName').value;
alert(saveAsFileName);
var fileFormat = saveAsFileName.substring(saveAsFileName.lastIndexOf("."));
if(fileFormat == '.docx') {
var toUnLockFile = 'MergeTest'+fileFormat;
var tempFileLocation = document.OA1.GetTempFilePath(saveAsFileName);
var tempToUnLockFileLocation = document.OA1.GetTempFilePath(toUnLockFile);
document.OA1.SaveAs(tempFileLocation,12);
document.OA1.SaveAs(tempToUnLockFileLocation,12);
document.OA1.HttpInit();
document.OA1.HttpAddPostFile(tempFileLocation);
document.OA1.HttpPost("");
document.OA1.ClearTempFiles();
} else {
alert("asdsa");
document.OA1.HttpInit();
document.OA1.HttpAddPostOpenedFile(saveAsFileName);
**zAu.send(new zk.Event(zk.Widget.$('$btnSave'), "saveFile", {'' : {'data' : {'nodeId': ''}}}, {toServer:true}));**
alert("moved");
}
}
In case of JSP page I can put my JSP URL in HttpPost but in case of ZK how to move from this JavaScript to Java method. So to overcome this problem I am using Widget to call saveFile() method which is in my viewmodel class. But zAu.send is not working fine. Can any body tell other solution to call my Java method from JavaScript in ZK MVVM.
Your code is simply wrong
zAu.send(new zk.Event(zk.Widget.$('$btnSave'), "onSaveFile", {'' : {'data' : {'nodeId': ''}}}, {toServer:true}));
Event names must start with on so this will fire a onSaveFile
event to the Component with id btnSave. Just listen to it.
My Problem: I write an automated system that needs to read .doc and .odt, performs some operation on it and exports it to pdf again.
Currently that works fine for everything I need, I could solve all problems until this one:
If a user provides a Document that had recorded changes (Redlines) I need to automatically accept all that changes or hide them.
I could solve that one with the code below as long as the OOo is showing on screen. When I launch it hidden, my calls do nothing at all.
So, here is what I do currently:
// DO NOT try to cast this to Desktop as com.sun.star.frame.Desktop is NOT a valid class!
// keep it as Object and cast it to XDesktop later (via queryInterface)
Object desktop = xMCF.createInstanceWithContext("com.sun.star.frame.Desktop", xContext);
XMultiServiceFactory xFactory = (XMultiServiceFactory) UnoRuntime.queryInterface(
XMultiServiceFactory.class, xMCF);
// what goes for desktop above is valid for DispatchHelper as well.
Object dispatchHelper = xFactory.createInstance("com.sun.star.frame.DispatchHelper");
// the DispatchHelper is the class that handles the interaction with dialogs.
XDispatchHelper helper = (XDispatchHelper) UnoRuntime.queryInterface(
XDispatchHelper.class, dispatchHelper);
XDesktop xDesktop = (XDesktop) UnoRuntime.queryInterface(com.sun.star.frame.XDesktop.class, desktop);
XFrame xFrame = xDesktop.getCurrentFrame();
XDispatchProvider xDispatchProvider = (XDispatchProvider) UnoRuntime.queryInterface(XDispatchProvider.class, xFrame);
// We issute the Track Changes Dialog (Bearbeiten - Änderungen // Edit - Changes) and tell it
// to ACCEPT all changes.
PropertyValue[] acceptChanges = new PropertyValue[1];
acceptChanges[0] = new PropertyValue();
acceptChanges[0].Name = "AcceptTrackedChanges";
acceptChanges[0].Value = Boolean.TRUE;
helper.executeDispatch(xDispatchProvider, ".uno:AcceptTrackedChanges", "", 0, acceptChanges);
// We issue it again to tell it to stop showing changes.
PropertyValue[] showChanges = new PropertyValue[1];
showChanges[0] = new PropertyValue();
showChanges[0].Name = "ShowTrackedChanges";
showChanges[0].Value = Boolean.FALSE;
helper.executeDispatch(xDispatchProvider, ".uno:ShowTrackedChanges", "", 0, showChanges);
My current guess is that I cannot call this because being hidden, I have no Frame to call any dispatcher to. But I could not find a way to get the Dispatcher for the Component.
I already tried to dispatch TrackChanges as well (to FALSE) but that didn't do it either.
After spending two days understanding the OOo API, I realized that the document isn't loaded in the frontend which is why this approach fails. However, you can modify the document's property directly:
XPropertySet docProperties = UnoRuntime.queryInterface(XPropertySet.class, document);
docProperties.setPropertyValue("RedlineDisplayType", RedlineDisplayType.NONE);
The property name "RedlineDisplayType" can be found in the RedlinePortion documentation
