I am implementing an Eclipse plugin for C programmers.
I can't find a way to get the variable that the user already highlited.(The user will highlight a variable in the editor and I need to know which variable it is/variable's name/location of this variable in the editor, like line number..)
Can anyone help to achieve that ?
Well after searching in some links, I achvieved that by using the ISelectionProvider and ITextSelection Interfaces. Here a code to get the name of the highlighted variable :
ISelectionProvider selProvider = textEditor.getSelectionProvider();
ITextSelection txtSel = (ITextSelection) selProvider.getSelection();
String varName = txtSel.getText();

Hi (most probably Peter), I am having troubles to figure out how to make parametrization of my RUTA project.
First of all I have several scripts that make kind of chain:
Project Adjectives.ruta
Project Anatomy.ruta (contains "SCRIPT Adjectives;" and "Document{->CALL(Adjectives)};")
Project Anamnesis.ruta (contains "SCRIPT Anatomy;" and "Document{->CALL(Anatomy)};")
For the result I am calling this:
File specFile = new File("C:/.../.../pipelines/AnamnesisEngine.xml");
String path = new File(specFile.toURI()).getParentFile().getAbsolutePath();
AnalysisEngineDescription desc = null;
String[] VarNames = {"Name1", "Name2"};
String[] VarValues = {"Value1", "Value2"};
try {
desc = AnalysisEngineFactory.createEngineDescriptionFromPath(
specFile.getAbsolutePath(), RutaEngine.PARAM_SCRIPT_PATHS, path+"/script",
RutaEngine.PARAM_DESCRIPTOR_PATHS, path+"/descriptor",
RutaEngine.PARAM_RESOURCE_PATHS,path+"/resources",
RutaEngine.PARAM_VAR_NAMES, VarNames,
RutaEngine.PARAM_VAR_VALUES, VarValues); ..... End so on (Those parameters (VarNames and VarValues) are filled from query, but that is not so important right now)
Everything works fine and I am getting nice JSON output. But now I am having troubles with those parameters (VarNames, VarValues) and I can't figure this out.
When I make something like this in script Anamnesis.ruta
STRING Name1;
Anamnesis{->SETFEATURE("Lemma",Name1)};
Everything works perfectly and I can see in my output that lemma for Anamnesis annotation is set to Value1...
However I also need to work with those variables in projects Adjectives.ruta and Anatomy.ruta. I suspect that those projects are controlled by their own descriptors (AdjectivesEngine.xml and AnatomyEngine.xml). Is there way to set the parameters for those projects and use them while creating ae from AnamnesisEngine.xml?
When I try to add this to Anatomy.ruta (And again call AnamnesisEngine.xml)
STRING Name1;
Anatomy{->SETFEATURE("Lemma",Name1)};
There is no Lemma at all in the output. Which kind of makes sense but I was hoping that maybe that whole chain can be controlled by AnamnesisEngine.xml and those first two projects would be able to "find", assign and work with those variables... Well I was wrong...
Please what would be the best way to achieve this?
If somebody is ever interested, I managed to achieve this with "Aggregate Engine Type" - which let's you import other descriptors into it and propagates variables into them... Epic!
I'm migrating some pre Java 10 code and I'm wondering if IntelliJ offers a way to automatically refactor the code to replace the variable declarations that uses the actual type with var wherever it's possible.
The code is full of stuff like:
String status = "empty";
BigDecimal interest = BigDecimal.ZERO;
List<Future<Boolean>> results = es.invokeAll(tasks);
LocalDate start = LocalDate.of(2020, 1, 1);
And I would prefer:
var status = "empty";
var interest = BigDecimal.ZERO;
var results = es.invokeAll(tasks);
var start = LocalDate.of(2020, 1, 1);
I already looked in IntelliJ's settings (Code Style/Inspections) and couldn't find anything.
Go to File | Settings, there select Editor | Inspections, then under Java | Java language level migration aids | Java 10.
Right click on Local variable type can be omitted and select Weak Warning or similar.
Move Your cursor onto any of those warnings in Your code (highlighted grey), open quick fix context help (alt+enter), at Replace explicit type with 'var' move to the right and select Fix all 'Local variable type can be omitted' problems in file
Thanks for #olga-klisho for the idea (in comments)
I'm using IntelliJ IDEA 2021.3.2, but don't think the setting is new.
I've been struggling with this one myself.
It seems that the first time to install IntelliJ locally, by default, it will fall back to using traditional defining of variables (i.e. String s = new String();)
How I managed to change it into using var is after I declared something, for example new String(), either I pressed ⌥ Alt/Option+Enter to declare a variable for that declaration or by using ⌘ Command+⇧ Shift+V shortcut (I'm using Mac and classic Intellij key mapping, so YMMV) which activates declaration of a variable, this would show as follows:
As you see, it suggest to hit that key combination shortcut or clicking on the settings button that would open a pop up like this one:
Make sure you have Declare var type selected and you should be good to go.
Use the IntelliJ Edit -> Find -> Replace... option.
Or Ctrl + R
Is there any Intellij Idea hotkey or a plugin to quickly insert variable into string?
e.g. i have string
"My code is working, yay! Result is = ",
and i have to add construction "+variable +", resulting in
"My code is working, yay! Result is = "+ variable +"."
to properly insert a variable.
When i have to insert variables into 20+ string, its driving me nuts :)
tried to find solution on google or plugin repository, no result
PS: i know about soutv hotkey, but it cant help me since i have to change already existing strings in code
Added Live Template
Abbreviation: ++
Description: Insert variable into string
Expand with: Enter
Template text: "+ $EXPR$ +" (do not forget double quotes)
Edit Template Variable:
expression:variableOfType("") default Value: "expr"
settings screen
You type ++ in a string, press Enter, and template text is added, and you only need to choose a variable. Works like a charm.
Thanks for the idea, #Meo
When using Eclipse spell check inside comments is enabled, but when entering for example :
String myString = "why isnt this getttting cheackedd";
Eclipse isn't checking spelling inside quotes,
is there a option to set this enable ? or do i have to download a plugin for this matter ?
thanks
You need to disable
"Ignore Java String literals" under eclipse
Preferences->General->Editors->Text Editors->Spelling.
Having a problem with the ast.newSimpleName() method.
I am not able to create a SimpleName of the sort 'SomeJava.class'. But the method works fine for names like 'SWT.None' or 'SomeJava.None'.
Here is the code :
MethodInvocation loggerInstance = ast.newMethodInvocation();
loggerInstance.setExpression(ast.newSimpleName("Logger"));
loggerInstance.setName(ast.newSimpleName("getLogger"));
String[] name1 = {className.replace(".java", ""),"None"};
String[] name2 = {className.replace(".java", ""), "class"};
loggerInstance.arguments().add(ast.newName(name1)); // This works
loggerInstance.arguments().add(ast.newName(name2)); // This doesn't
Should i use any thing else other than SimpleName for this. Thanks in advance.
Edit : This is the statement i want to construct:
Logger.getLogger(ClientTest.class);
During my analysis, i found out that the problem arises when using the "class" literal. Not sure how to overcome this.
ast.newName("class");
ast.newSimpleName("class");
Use ASTView plugin (http://www.eclipse.org/jdt/ui/astview/index.php) to see what is the type of node for 'ClientTest.class' and then construct that type of node.
Got it from ASTView. Finally downloaded and installed it. :)
It should be a generated as a TypeLiteral, not as a SimpleName/Name.
TypeLiteral typeLiteral = ast.newTypeLiteral();
typeLiteral.setType(ast.newSimpleType(ast.newSimpleName(className)));
