How to generate javadoc comments in Android Studio - android-studio

Can I use shortcut keys in Android studio to generate javadoc comments?
If not, what is the easiest way to generate javadoc comments?

I can't find any shortcut to generate javadoc comments. But if you type /** before the method declaration and press Enter, the javadoc comment block will be generated automatically.
Read this for more information.

To generatae comments type /** key before the method declaration and press Enter. It will generage javadoc comment.
Example:
/**
* #param a
* #param b
*/
public void add(int a, int b) {
//code here
}
For more information check the link
https://www.jetbrains.com/idea/features/javadoc.html

Here is an example of a JavaDoc comment from Oracle:
/**
* Returns an Image object that can then be painted on the screen.
* The url argument must specify an absolute {#link URL}. The name
* argument is a specifier that is relative to the url argument.
* <p>
* This method always returns immediately, whether or not the
* image exists. When this applet attempts to draw the image on
* the screen, the data will be loaded. The graphics primitives
* that draw the image will incrementally paint on the screen.
*
* #param url an absolute URL giving the base location of the image
* #param name the location of the image, relative to the url argument
* #return the image at the specified URL
* #see Image
*/
public Image getImage(URL url, String name) {
try {
return getImage(new URL(url, name));
} catch (MalformedURLException e) {
return null;
}
}
The basic format can be auto generated in either of the following ways:
Position the cursor above the method and type /** + Enter
Position the cursor on the method name and press Alt + Enter > click Add JavaDoc

You can install JavaDoc plugin from Settings->Plugin->Browse repositories.
get plugin documentation from the below link
JavaDoc plugin document

Javadoc comments can be automatically appended by using your IDE's autocomplete feature. Try typing /** and hitting Enter to generate a sample Javadoc comment.
/**
*
* #param action The action to execute.
* #param args The exec() arguments.
* #param callbackContext The callback context used when calling back into JavaScript.
* #return
* #throws JSONException
*/

You can use eclipse style of JavaDoc comment generation through "Fix doc comment".
Open "Preference" -> "Keymap" and assign "Fix doc comment" action to a key that you want.

Here we can some something like this.
And instead of using any shortcut we can write "default" comments at class/ package /project level. And modify as per requirement
*** Install JavaDoc Plugin ***
1.Press shift twice and Go to Plugins.
2. search for JavaDocs plugin
3. Install it.
4. Restart Android Studio.
5. Now, rightclick on Java file/package and goto
JavaDocs >> create javadocs for all elements
It will generate all default comments.
Advantage is that, you can create comment block for all the methods at a time.

In Android Studio you don't need the plug in. On A Mac just open Android Studio -> click Android Studio in the top bar -> click Prefrences -> find File and Code Templates in the list -> select includes -> build it and will be persistent in all your project

Another way to add java docs comment is press : Ctrl + Shift + A >> show a popup >> type : Add javadocs >> Enter .
Ctrl + Shirt + A: Command look-up (autocomplete command name)

Add Javadoc
/** + return
set cursor inside method name -> ⌥ Option + return -> Add Javadoc

Simply select (i.e. click) the method name, then use the key combo Alt+Enter, select "Add JavaDoc"
This assumes that you have not already added comments above the method, else the "Add JavaDoc" option will not appear.

In Android studio we have few ways to auto-generated comments:
Method I:
By typing /** and Then pressing Enter you can generate next comment line and it will auto-generate the params, etc. but when you need the hotkey for this check out method II on below.
**Method II: **
1 - Goto topMenu
2 - File > Settings
3 - Select Keymap from settings
4 - On the top right search bar search for "Fix Doc"
5 - Select the "fix doc comment" from the results and double-click on it
6 - Select Add keyboard shortcut from the opened drop down after double-click
7 - Press the shortcut keys on the keyboard
8 - Goto your code and where you want to add some comment press the shortcut key
9 - Enjoy!

Just select the Eclipse version of the keycap in the Keymap settings.
An Eclipse Keymap is included in Android Studio.

i recommendated Dokka for geneate javadoc with comment and more

I'm not sure I completely understand the question, but a list of keyboard short cuts can be found here - Hope this helps!

Android Studio -> Preferences -> Editor -> Intentions -> Java -> Declaration -> Enable "Add JavaDoc"
And, While selecting Methods to Implement (Ctrl/Cmd + i), on the left bottom, you should be seeing checkbox to enable Copy JavaDoc.

Because almost of us use Kotlin, you can generate JavaDoc (KDoc) using plugins. In Android Studio open Settings (press Ctrl+Alt+S), select Plugins and find kdoc. I downloaded KDoc-er, but you can choose any of them. Then restart Android Studio.
Find any class/method, type /**, press Enter. You will get a short description like:
/**
* User data
*
* #property name
* #property avatar
* #property gender
* #constructor Create empty User data
*/
class UserData(...

to generate javadoc comment use
/**
Your docs
*/

ALT+SHIFT+G will create the auto generated comments for your method (place the cursor at starting position of your method).

Can I make Android Studio generate Dart constructors code with named parameters and add key?

When I auto generate dart constructors, I would like the generator to make my constructors using named parameters and add key.
(Curly braces wrapping the constructor arguments)
Is there some easy trick I can perform to make Android Studio do this for me?
// Auto generated constructor without named parameters.
// This is how Android studio currently generates my Widget constructors.
class MyTestModel {
MyTestModel(this.a, this.b, this.c);
final String a;
final String b;
final String c;
}
// Constructor with named parameters and key.
// This is how I would like Android Studio Auto Generate to behave.
class MyTestModelB {
MyTestModelB({Key key, this.a, this.b, this.c}) : super(key: key);
final String a;
final String b;
final String c;
}
So another way to phrase my question:
When I press "Command + N" and I use Android Studio to automatically generate my Dart constructor.
Currently Android Studio does not generate Named Parameter Constructors for me, neither does it add a key to the constructors.
Somewhere I guess there is a Template of some kind that Android Studio uses to autogenerate those constructors.
I guess I need to access that Template and modify it to have it autogenerate Named Parameter Constructors for me, and add key.
But where is it?
My installation of Flutter/Dart/Android studio is rather new.
From April/May 2020.
The default constructor generator from Cmd+N (MacOS) will not generate named parameters constructor. You need to highlight one of your final variable (must be final), wait for the popup (see video clip) and select generate constructor from final field or press alt+shift+enter.
If you are looking for the 'named argument constructor' option in the generate menu, then you should install Dart Data Class Plugin.
Ok, I don't know what has happened to my Android Studio, but now I can generate the constructors like a want them. Something must have happened! Maybe something got installed or updated? I don't know. If you know where exactly the settings for auto generate of Flutter constructors happens in Android Studio, I am interested to know. This is how my constructors look now:
class Avatar extends StatelessWidget {
final String photoUrl;
final VoidCallback onPressed;
const Avatar({Key key, this.photoUrl, this.onPressed}) : super(key: key);
}

Generate method or class comments in kotlin

I'm using Android Studio 3.0.1. I can hit fix doc comment to insert comment of method quickly in Java, but not effective in Kotlin. How can I solve it?
When you're typing # inside a kdoc, you'll see auto complete for #param, and after #param you'll see all parameters, and currently you cannot complete all parameters within one click.
Mention the /** */ comments are called kdoc in Kotlin, which is not javadoc.
Kotlin and especially KDoc encourage a different documentation style. As stated in this discussion:
The reason is that we found that referring to parameter names from the documentation text allows to write documentation that is more concise and easier to read compared to the traditional javadoc style where every parameter is documented in a separate tag. Therefore, we do not generate the template with parameter names by default. (D. Jemerov, Kotlin in Action Author)
Here’s an example of let, which is part of the standard library:
/**
* Calls the specified function [block] with `this` value as its argument and returns its result.
*/
#kotlin.internal.InlineOnly
public inline fun <T, R> T.let(block: (T) -> R): R

Can't get custom block module to appear in "Place blocks" screen in Drupal 8

I am trying to write a custom block module in drupal 8 that will allow me to place this block into my drupal pages using the block layout screen.
I'm very new to drupal - so this is very much a "hello world" project (initially) to figure out how this works. To this end, I have been following youtube video instructions as well as reading through whatever doco I can find on the net [and also a couple of books], but to no avail [yet].
What I have done, is created a directory "walker" in the modules folder in which I have created Walker.info.yml which looks like this:
name: Walker
description: A filewalker
core: 8.x
package: Custom
type: module
In the same directory I have created Walker.module which looks like this:
<?php
/**
* #file
* Code for the walker module.
*/
I have then created a directory:
module/walker/src/Plugin/Block/
and created a file called WalkerBlock.php with the following content:
<?php
/**
* #file
* Code for the walker block.
*/
namespace Drupal\walker\Plugin\Block;
use Drupal\Core\Block\BlockBase;
/**
* Provides a walker block
*
* #Block(
* id = "walker",
* admin_label = #Translation("The walker block"),
* category = #Translation("Blocks")
* )
*/
class WalkerBlock extends BlockBase
{
public function build()
{
return array('#markup' => 'Walker block');
}
}
If I run the command "find . -type f | grep Walker" from my root Drupal directory, I get the following output:
./modules/Walker/Walker.module
./modules/Walker/src/Plugin/Block/WalkerBlock.php
./modules/Walker/Walker.info.yml
Yet, though the documentation and videos I have read suggest that this should be all I require, the Walker block does not appear in the block layout screen as an option that I can place in one of the block regions.
Can anyone see what I'm doing wrong? I have been going around and around in circles for hours now.
Note also, that I have gone to the drupal8/admin/config/development/performance screen and clicked the "Clear all cache's" button
Thanks heaps for any assistance,
David Buddrige :-)
Check the module where you defined you block plugin is installed or not. If the module is not installed, go to the extend page of your site search for your module name and enable it. If you are using drush then you can simply enable it by
drush en moduleName
After that, I think you will get the block name in place block of your block layout section.

Android Studio: $END$ and $SELECTION$ in live template

I cannot get cursor in $END$ position when template inserted without surrounding (with selected text it works fine).
//region MyRegion
$SELECTION$$END$
//endregion
Is it possible to solve it in any way?
Android Studio version is 2.2.3.
UPDATE
To make question clear I have added steps to reproduce:
1) Create live template (surrounding) as it is specified above.
2) Give it some name, for example #mrgn.
3) Inside some class try to use it. So type #mrgn and press TAB.
It should insert the following text:
public class SomeClass {
//region MyRegion
< cursor should be here
//endregion
}
But it inserts text and place cursor in wrong place:
public class SomeClass {
//region MyRegion
< cursor is here.. but spaces are inserted, so only cursor does not work.
//endregion
}
You can fix this by creating 2 Live Templates. one for the surround one without.
Unfortunately that means that you will need to put up with 2 different aliases.
'regionSur'
//region MyRegion
$SELECTION$$END$
//endregion
'region'
//region MyRegion
$END$
//endregion
This isn't so bad, as the only time you see the surround syntax is when using the keyboard shortcut, instead of the auto complete lists.
The actual bug lies in the behaviour of $selection$ when it is empty, $END$ works fine.

Does anyone know where to find a SS2.0 JSDOC definition library?

Does anyone know or has a JSDOC definition library I can use for SS2.0??
The current one I have for SS1.0 looks like the one below, and I use it to plug into my IDE and get autocompletion.
/** * Loads an existing saved search. The saved search could have been created using the UI, or created using nlapiCreateSearch(type, filters, columns) in conjunction with nlobjSearch.saveSearch(title, scriptId).
*<br>API Governance: 5
* #param {String} recType [optional] - The record internal ID of the record type you are searching (for example, customer|lead|prospect|partner|vendor|contact). This parameter is case-insensitive.
* #param {String} searchId - The internal ID or script ID of the saved search. The script ID of the saved search is required, regardless of whether you specify the search type. If you do not specify the search type, you must set type to null and then set the script/search ID.
* #returns {nlobjSearch} nlobjSearch
* #since 2012.1 */
function nlapiLoadSearch(recType, searchId) { };
Not really a technical question but would come in handy for everyone.
You may consider what I did which there is no need to download other plugins. You will be able to enable the code assist if you have the copy of SS2.0 API and then use "#param" and "#type" JSDOC tag.
Then, there will be suggestion every time you type then 'CTRL' + 'SPACE".
Aside from that, your IDE will also provide description for each function.
So this is what will you do.
On your NetSuite accoun, download the SuiteScript 2.0 JavaScript files. You can do this by nagaviting at >Documents>Files>SuiteScripts>. Then at right portion of your screen, you should see links for "SuiteScript 2.0 API" and "SuiteSCript 1.0 API". Click for SS2.0 to download.
On Eclipse IDE, create a new JavaScript project for SS2.0 or include it on your existing project.
Next on the project you are working, right click then select “Properties”. Under >JavaScript>Include Path and then at “Projects” subtab, add the project where SS2.0 APIs are included.
You will now have code assist for object literal APIs of SS2.0. These are 'N/log' and 'N'util' modules.
Next to enable the code assist for object constructor APIs of SS2.0 like 'N/record' and 'N/search' modules, we should be adding "#param" JSDoc tag on each function declaration.
So if we are going to use the 'N/record', 'N/search' and 'N/error' modules in our script, we should have below sample comments before function declaration. But please take note that it should match the value inside the "{[VALUE HERE]}" tag and the module name. Also the variable name on the comment section and function declaration.
/**
* Do something.
*
* #param {record} objRec
* #param {search} objSearch
* #param {error} objError
*
*/
function doSomething(objRec, objSearch, objError)
{
//CODE HERE
}
You may also use '#type' for your variable declaration. Below is the sample code.
/**
* Do something.
*
*/
function doSomething()
{
/*** #type record**/
var recCustomerRefund = record.create(
{
type : 'customerrefund',
isDynamic : true
});
}
The way SS2 works you are essentially out of luck.
consider
define(['N/search'], function(bob){
var srch = bob.load({id:'customsearch_my_search'});
}
What is bob? Your IDE will have to be considerably smarter to know that bob is part of the search namespace. It's of course doable but less likely to work with a simple downloadable file that you can just plug into your IDE. If you just use 'search' that may make things more likely to work but now you've used up a very generic name that you cannot use elsewhere.
Also if an IDE can determine what 'bob' is now your arguments is an unordered hash so positional #params don't work anymore.
Typescript may help. I've been maintaining a Typescript definition file for SS1 at https://github.com/BKnights/KotN-Netsuite. As I start doing more with SS2.0 I may do the same for that. Then your IDE would have more of a chance:
define(['N/search'], function(bob:NSearch){...
So your Typescript aware IDE could use that for member completion and at least you'd have a compile time check on types
