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
I am using selenium to verify a web site where doctors' names appear in a drop-down box. If the name in the database has extra spaces (like "Kildare , Jack , MD") the blanks should be removed like "Kildare, Jack MD". I am using the selenium method select.getOptions() (where select is the web element of a select box).
When I retrieve the date from the box and print it, it shows the names as still having spaces (see Alois Alzheimer and Sigmund Freud below). In the text box visually it shows Sigmund Freud formatted correctly, but Alois Alzhemier still has a space after Alois (see the attached picture). I am not sure what is happening here. Looks like the select box occasionally removes blanks itself and sometimes doesn't. Any clues?
Here is the debug text from select box:
DEBUG [PP21644] ----<Alzheimer, Alois , DO>-----
DEBUG [PP21644] ----<Freud, Sigmund Schlomo, Jr, MD>-----
DEBUG [PP21644] ----<Mayo, Charles Mayo, MMIN>-----
And the picture of how it looks is attached. Sigmund is formatted correctly but Alois is not (see the space highlighted with a yellow square). And yes, I had to run this with famous doctors' names to protect the names of the actual providers.
There are a few ways you could do this
You could examine the HTML of the OPTIONs and figure out where the spaces are coming from, parse it, etc. to get rid of the spaces. I can't really offer code here since I don't know what the HTML looks like.
Another way given what you provided is to use regex and .replace() to remove repeated spaces and to remove a space before a comma.
public static void main(String[] args)
{
String s1 = "Alzheimer, Alois , DO";
String s2 = "Freud, Sigmund Schlomo, Jr, MD";
String s3 = "Mayo, Charles Mayo, MMIN";
System.out.println(cleanup(s1));
System.out.println(cleanup(s2));
System.out.println(cleanup(s3));
}
public static String cleanup(String s)
{
return s.replaceAll(" +", " ").replace(" ,", ",");
}
I ma making a game, and I want to pull the apprpriate dialog from the resource file, but which string to pull changes from level to level.
How would I get this to work?
I would want something like:
int level = 3;
String dialog = getResources().getString(R.string.["level_dialog_"+level]);
With the goal being that the apprpriate string resource ID is found using the name of the string resource plus the level. But of course that won't even compile.
What is the right way to do this?
Thanks AJcodez for getting me thinging along the right path. Even if you answer was not the right one.
I found the right answer myself:
To get a resource by string name, there is already an android function as part of the Resources object:
int id = getResources().getIdentifier("level_"+1+"_intro", "array", getPackageName());
String[] level1 = getResources().getStringArray(id);
The first line, I get the resource id. The parameters are the name of the resournce, the type (array, id, string, drawable, etc) and the third parameter is the package name.
In the second line, I can now get the resource just like I would using R.array.
(note to self: RTFM)
I would store your strings in a string-array, and then access the strings through the index of the array. See here: http://developer.android.com/guide/topics/resources/string-resource.html#StringArray
I need to translate my app, so i want to use gettext-common from http://code.google.com/p/gettext-commons
I checked out the svn and tried to compile the example:
javac -classpath ../java I18nExample.java
java -classpath ../../target/gettext-commons-0.9.6.jar:. I18nExample
The program does not give me the targeted output; I have absolutely no idea whats going on!
It seems that the de.properties is completly ignored. If I set the Properties file to "de" in the Factory's constructor, I get partly the output I want to see.
Is there anywhere in the internet a working example of gettext for java?
this is the output from the example script:
First run
This text is marked for translation and is translated
This text is marked for translation but not translated
This text is marked for translation but not translated
Four: 4
chat
chat
1 file is open
2 files are open
Second run
This text is marked for translation and is translated
This text is marked for translation but not translated
This text is marked for translation but not translated
Four: 4
chat
chat
1 file is open
2 files are open
There are a couple of issues, perhaps due to the build process.
First, for the message lookup to work, I needed to move the en and de resources into Messages_en.properties and Messages_de.properties in order to make a real resource bundle.
Second, the example code tries to use messages with no translations available, like the "file is open" stuff. Here's an updated version of what I tried; this all appears to work with the above modification:
public static void main(String[] args) {
I18n i18n = I18nFactory.getI18n(I18nExample.class, "Messages");
for (int i = 0; i < 2; i++) {
if (i == 0) {
print("First run");
} else {
print("Second run");
i18n.setLocale(Locale.GERMAN);
}
print("Current locale: " + i18n.getLocale());
print(i18n.tr("This text is marked for translation and is translated"));
String mark = i18n.marktr("This text is marked for translation but not translated");
print(mark);
print(i18n.tr(mark));
mark = i18n.tr("This is the {0}. text to be translated", "chat (noun)");
print(mark);
mark = i18n.tr("This is the {0}. text to be translated", "chat (verb)");
print(mark);
print(i18n.tr("chat (noun)"));
print(i18n.tr("chat (verb)"));
print("");
}
}
Note also that to insert translated words, you need something like this:
print(i18n.tr("This is the {0}. text to be translated", i18n.tr("chat (noun)")));
print(i18n.tr("This is the {0}. text to be translated", i18n.tr("chat (verb)")));
However, without un-banging (removing the ! and providing an English translation in Messages_en.properties, it shows up as chat (noun), which... strikes me as being almost useless.
The documentation is lacking on this aspect.
I want to use regions for code folding in Eclipse; how can that be done in Java?
An example usage in C#:
#region name
//code
#endregion
Jet Brains IDEA has this feature. You can use hotkey surround with for that (ctrl + alt + T). It's just IDEA feature.
Regions there look like this:
//region Description
Some code
//endregion
There's no such standard equivalent. Some IDEs - Intellij, for instance, or Eclipse - can fold depending on the code types involved (constructors, imports etc.), but there's nothing quite like #region.
With Android Studio, try this:
//region VARIABLES
private String _sMyVar1;
private String _sMyVar2;
//endregion
Careful : no blank line after //region ...
And you will get:
No equivalent in the language... Based on IDEs...
For example in netbeans:
NetBeans/Creator supports this syntax:
// <editor-fold defaultstate="collapsed" desc="Your Fold Comment">
...
// </editor-fold>
http://forums.java.net/jive/thread.jspa?threadID=1311
Custom code folding feature can be added to eclipse using CoffeeScript code folding plugin.
This is tested to work with eclipse Luna and Juno. Here are the steps
Download the plugin from here
Extract the contents of archive
Copy paste the contents of plugin and features folder to the same named folder inside eclipse installation directory
Restart the eclipse
Navigate Window >Preferences >Java >Editor >Folding >Select folding to use: Coffee Bytes Java >General tab >Tick checkboxes in front of User Defined Fold
Create new region as shown:
Restart the Eclipse.
Try out if folding works with comments prefixed with specified starting and ending identifiers
You can download archive and find steps at this Blog also.
For Eclipse IDE the Coffee-Bytes plugin can do it, download link is here.
EDIT:
Latest information about Coffee-Bytes is here.
This is more of an IDE feature than a language feature. Netbeans allows you to define your own folding definitions using the following definition:
// <editor-fold defaultstate="collapsed" desc="user-description">
...any code...
// </editor-fold>
As noted in the article, this may be supported by other editors too, but there are no guarantees.
the fastest way in Android Studio (or IntelliJ IDEA)
highlight the code you want to surround it
press ctrl + alt + t
press c ==> then enter the description
enjoy
AndroidStudio region
Create region
First, find (and define short cut if need) for Surround With menu
Then, select the code, press Ctrl+Alt+Semicolon -> choose region..endregion...
Go to region
First, find Custom Folding short cut
Second, from anywhere in your code, press Ctrl+Alt+Period('>' on keyboard)
Contrary to what most are posting, this is NOT an IDE thing. It is a language thing. The #region is a C# statement.
I were coming from C# to java and had the same problem and the best and exact alternative for region is something like below (working in Android Studio, dont know about intelliJ):
//region [Description]
int a;
int b;
int c;
//endregion
the shortcut is like below:
1- select the code
2- press ctrl + alt + t
3- press c and write your description
The best way
//region DESCRIPTION_REGION
int x = 22;
// Comments
String s = "SomeString";
//endregion;
Tip: Put ";" at the end of the "endregion"
If anyone is interested, in Eclipse you can collapse all your methods etc in one go, just right click when you'd normally insert a break point, click 'Folding' > 'Collapse all'. It know it's not an answer to the question, but just providing an alternative to quick code folding.
here is an example:
//region regionName
//code
//endregion
100% works in Android studio
#region
// code
#endregion
Really only gets you any benefit in the IDE. With Java, there's no set standard in IDE, so there's really no standard parallel to #region.
I usually need this for commented code so I use curly brackets at start and end of that.
{
// Code
// Code
// Code
// Code
}
It could be used for code snippets but can create problems in some code because it changes the scope of variable.
vscode
I use vscode for java and it works pretty much the same as visual studio except you use comments:
//#region name
//code
//#endregion
Meet custom folding regions ⌥⌘T
Actually johann, the # indicates that it's a preprocessor directive, which basically means it tells the IDE what to do.
In the case of using #region and #endregion in your code, it makes NO difference in the final code whether it's there or not. Can you really call it a language element if using it changes nothing?
Apart from that, java doesn't have preprocessor directives, which means the option of code folding is defined on a per-ide basis, in netbeans for example with a //< code-fold> statement
On Mac and Android Studio follow this sequence:
Highlight the source code to fold
Press Alt+Command+t
Select <editor-fold>
Also you can select other options:
In Visual Studio Code, try this:
//region Variables
// Code you need
//endregion
In Eclipse you can collapse the brackets wrapping variable region block. The closest is to do something like this:
public class counter_class
{
{ // Region
int variable = 0;
}
}
Just intall and enable Coffee-Bytes plugin (Eclipse)
There is some option to achieve the same, Follow the below points.
1) Open Macro explorer:
2) Create new macro:
3) Name it "OutlineRegions" (Or whatever you want)
4) Right Click on the "OutlineRegions" (Showing on Macro Explorer) select the "Edit" option and paste the following VB code into it:
Imports System
Imports EnvDTE
Imports EnvDTE80
Imports EnvDTE90
Imports EnvDTE90a
Imports EnvDTE100
Imports System.Diagnostics
Imports System.Collections
Public Module OutlineRegions
Sub OutlineRegions()
Dim selection As EnvDTE.TextSelection = DTE.ActiveDocument.Selection
Const REGION_START As String = "//#region"
Const REGION_END As String = "//#endregion"
selection.SelectAll()
Dim text As String = selection.Text
selection.StartOfDocument(True)
Dim startIndex As Integer
Dim endIndex As Integer
Dim lastIndex As Integer = 0
Dim startRegions As Stack = New Stack()
Do
startIndex = text.IndexOf(REGION_START, lastIndex)
endIndex = text.IndexOf(REGION_END, lastIndex)
If startIndex = -1 AndAlso endIndex = -1 Then
Exit Do
End If
If startIndex <> -1 AndAlso startIndex < endIndex Then
startRegions.Push(startIndex)
lastIndex = startIndex + 1
Else
' Outline region ...
selection.MoveToLineAndOffset(CalcLineNumber(text, CInt(startRegions.Pop())), 1)
selection.MoveToLineAndOffset(CalcLineNumber(text, endIndex) + 1, 1, True)
selection.OutlineSection()
lastIndex = endIndex + 1
End If
Loop
selection.StartOfDocument()
End Sub
Private Function CalcLineNumber(ByVal text As String, ByVal index As Integer)
Dim lineNumber As Integer = 1
Dim i As Integer = 0
While i < index
If text.Chars(i) = vbCr Then
lineNumber += 1
i += 1
End If
i += 1
End While
Return lineNumber
End Function
End Module
5) Save the macro and close the editor.
6) Now let's assign shortcut to the macro. Go to Tools->Options->Environment->Keyboard and search for your macro in "show commands containing" textbox (Type: Macro into the text box, it will suggest the macros name, choose yours one.)
7) now in textbox under the "Press shortcut keys" you can enter the desired shortcut. I use Ctrl+M+N.
Use:
return
{
//Properties
//#region
Name:null,
Address:null
//#endregion
}
8) Press the saved shortcut key
See below result:
