vscode-kotlin's Issues

Safe call ("someVariable.?test()") Syntax highlighting is broken

The variable gets wrongly highlighted as it follows

Support for annotations

Could we get syntax highlighting for things like @JvmStatic, @JvmField, @throws annotations?

Code Snippet not work

How do I make the code snippet work? I try to trigger the code snippet with ctrl + space, but nothing there.

Support for imports

Add auto-import support the same way Java plugin provide you with hints on where you can find un-imported objects.

'qualified this' (this@Activity) is not correctly highlighted

[email protected](R.a.b)
//            ^ these are also highlighted as keywords

poposed solution:
changing '/syntaxes/Kotlin.tmLanguage': line 624:
from

line 624:            <string>\b(this|super)\b</string>

to

line 624:            <string>\b(this|super)(@\w+)?\b</string>

Syntax highlighting problem with if expression

There seems to be a problem when highlighting this code. For some reason, after min function, the comments and the function below seem to break

After further testing, the issue exist in the if statement.

Specific kotlin codeblock breaks markdown document

First, look at the following.

You can see that the text after the code block is affected by syntax highlighting. I found that the same thing happens when we write certain code within a code block. The easiest way to reproduce this is to write only one "{" character.

I thought it was a bug, so I reported it. thanks.

Handle speech-mark at end of raw string

I noticed that syntax highlighting breaks if you have a speech-mark at the end of your raw string. e.g.

test = """"foo""""

Any subsequent lines will be highlighted as string content.

If there's a space between the speech-mark and the closing triple-speech-marks, it works fine. e.g.

test = """"foo" """

It also works if there are two speech marks. e.g.

test = """"foo"""""

I suspect as soon as it sees the first three speech-marks at the end, it ends the string literal. The fourth speech-mark then incorrectly begins a new string literal.

Sintax hightlight is broken when use String interpolation

Colorizing part of the variable name when it ends with "?."

If we are using "?." operator on variable containing capital letter, formatter thinks it is a class name:

The Kotlin Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted.

I got this notification in VS code.

The Kotlin Language Server server crashed 5 times in the last 3 minutes. The server will not be restarted.

And try to follow the instruction in Developer Tools I got another message.

Hover Provider to show docs

Problem

You don't see the documentation in the tooltip when hovering over a code element.

Solution

Add a hover provider that displays the information.

Or are the docs only for me not showing?

No methods outline with this plugin

This plugin does not enable the OUTLINE view to list any methods, functions or variables whatsoever. Nothing at all is shown.

Incorrect string interpolation parsing leaves closing quotes undetected

Possibly related to #35 string interpolation parsing will sometimes fail to detect the closing quotes incorrectly classifying the follow-up code.

Add support for Kotlin-JS

Hi
I develop online apps and find VSC a great tool.
For all the client (browser) code I use Kotlin-JS but the plugin keeps complaining about unresolved references (like in e.g. import org.w3c.dom.* ) or unsupported context (like dynamic) although the compiler runs through without problems. Can you please complete these references, or give advise for configuring the plugin!?

thx

FR: Syntax colorize var-created variables differently to val-created variables (values)

Any interest in syntax colouring the mutable variables declared with var, with a different colour from the immutable variables (values) declared with val?

I noticed F# has this feature, it really makes you take notice which variables are not immutable.

Worth a shot asking, thanks for making a great plugin. :)

Customizable colors

Should be some way to customize the colors. Currently, the syntax highlighting is basically useless as almost everything is in the same color.

Why there is no problems at the corner of editor when prolem file is open?

When I'm opening any file with error there is no highliting for this problem. Why?

As of Kotlin 1.3, unsigned datatypes

As of Kotlin 1.3, unsigned datatypes** in common/jvm/native:

** UInt, UIntArray, ULong, etc., etc.

Tabs for indentation

Hi,

Is there a way to get tabs (4 characters wide, not spaces) when using your extension?

That's my personal preference even if it's not Kotlin's official style.

I tried this in VS Code settings JSON file but it seemingly did nothing... Still getting 2 spaces for each Tab press.

"[kotlin]": {
	"editor.tabSize": 4,
},

support install in remote machine

Support Kotlin Debugging

I'm not able to set breakpoints in Kotlin files within vs code, possibly because this extension does not yet support Kotlin debugging

Add full auto completion

Hello, please add this auto-complete feature to this plugin.
Without this feature, the plugin does not work at all. Thank .

Added error detection

Hello . Please add error detection.
Unfortunately, this plugin does not detect the error.

Kotlin icon does not display for Kotlin scripts (files with *.kts extension)

In VS Code, the extension provides a nice looking icon for regular Kotlin files (*.kt) but not for Kotlin script files (*.kts).

It would be nice if the icon were used for Kotlin scripts as well.

Highlighting sometimes off

As you can see, it is confused by comments. Also sometimes happens in other situations:

No syntax highlighting

No syntax errors are highlighted, no matter how blatant. Am I doing something wrong?

Support for Kotlin code in Markdown documents

Code blocks starting with ```kotlin are not highlighted in Markdown documents.

Use GitHub releases for vsix

Although the vsix are currently rather light, doing this would make tags a necessity and make the download and install of these binaries more logical.

Is this plugin still maintained?

The last commit to master was in July and there are multiple PR from over 2 months ago open with no comments... So my question stands, is this plugin still maintained?
If not the repository should probably be marked as deprecated.

Syntax highlighting breaks after < and <= operators

Integrate idea plugin

I'm wondering how much work would require to integrate the plugin used by intellij idea community edition. It has a lot of features including static analysis, formatter, goto declaration, refactor and similar stuff. What do you think, is it doable?

won't install in devcontainer

Why this plugin cannot be installed inside a devcontainer?

Markdown Syntax Highlighting

Hi,

Syntax highlighting in markdown is code blocks is still not working for me. It was supposed to be fixed in #11

In a markdown document if I place something like this it will not be highlighted:

val len = text?.run {
    println("get length of $this")
    length //`this` can be omitted
} ?: 0

Thanks,
Ivan

Doesn't work in VS Code

thank you for reading this issue before, am tried to installing this extension on my VS Code. It's done properly. But, when am try to running my code. vs code said : You don't have an extension for debugging Kotlin. Should we ..... ?

what I suppose to do with that ? there is any more guide for me to solve this ?

print() highlighting not working

The highlighting color of the "println" function works as expected, but the color of "print" does not (it stays white, e.g.). Here's what it looks like:

Support for Kotlin formatter

🙏

kotlin support in markdown documents is missing

I have not used this plugin before but according to this fix #6 I would expect that the following section is highlighted in the editor of an .md file:

var x=3

It doesn't nor any other text I place inside.

End of line comments not always syntax highlighted

As shown in the image, some comments are missed by the syntax highlighter.

EDIT: changed image to include a properly highlighted comment for comparison.

Char literal syntax highlighting wrong for double-quote '"'

Issue Type: Bug

The Kotlin syntax for a double-quote char literal is '"'. Enter this by typing '"'. This syntax is highlighted incorrectly in vscode. It's highlighted as if the double-quotes somehow trump the single-quote char literals, which they should not.

Here is some Kotlin source code that illustrates the problem.

val a = '"'
val dummy1 = 1
val b = '"'
val dummy2 = 2

Here is an image showing the incorrect syntax highlighting in vscode:

Compare to an image of some correct highlighting from Android Studio:

Syntax Highlight broken when quote and double-quotes are used

For example, the code ssid.trim('"') will break it. See the image attached.
