I just installed your plugin and started vim with a Kotlin file. First thing happening is this:

$ vim build.gradle.kts
Fehler beim Ausführen von "~/.vim/plugin/kotlin-vim/syntax_checkers/kotlin/kotlinc.vim":
Zeile   99:
E121: Undefinierte Variable: g:SyntasticRegistry
Betätigen Sie die EINGABETASTE oder geben Sie einen Befehl ein

Using hi def let's user override stuff, in color themes etc., I'm a heavy user of that and it was not working for kotlin.

Also current syntax is commonly defined at the end.

" to ' to make vim linter happy :)

Hope this helps and thnx for Kotlin!

As listed here: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/index.html

Fixes #12.

Realized after I made these changes that this conflicts with #32, which also adds some missing types but not all of these...

The whole of the following program is highlighted as a comment for me in vim 7.4 (Ubuntu 14.04):

/* Hello, world! */

fun main(args: Array<String>) {
    println("Hello, world!")
}

The problem appears to be that /* is matched as the start of the inner/contained region rather than the start of the outer/containing region i.e. this works:

/* */ */

fun main(args: Array<String>) {
    println("Hello, world!")
}

The documentation doesn't help much, but using a matchgroup (and not giving it the same name as the region) seems to solve the problem, and even handles /*/**/*/ and /* */* (via) correctly.

I also updated the README to include Vundle and Pathogen installation instructions.

This may not be an issue but a configurations error instead, I'm new to vim, I already searched for related solutions to my issue but I find none. I directed here to find some answers.

The plugin as it stands does not set the comment syntax, which means various Vim features acting on comments don't work properly.

This adds settings for comment syntax when editing Kotlin files.

Pictures say more than words, so here is one.

Function/constructor calls aren’t highlighted yet. I would like to add that as well, but that feels like a separate issue to me, and I don’t know if you even want it.

This allows us to have C-style comments in kotlin, a la:

/**
 * Start of comment
 *
 * More comment
 */

and have vim autoindent them (according to your formatoptions setting, that is). I copied the setting from the builtin ftplugin for JavaScript, since they have equivalent comment syntax.

Vim 8.1 does not detect *.kt nor *.kts files as kotlin.

Would you consider sending this plugin upstream to https://github.com/vim/vim/ ? All that's needed is for you (the author) to create an issue at https://github.com/vim/vim/ , point to this repo and say that you are the author and you would like it to be included.

As far as I know, the number constants like '1_000_000', '0xFF_EC_DE_5E' and '0b11010010_01101001_10010100_10010010' are also valid, so I updated these three patterns. By the way, the pattern for binary numbers should accept 0 and 1 only, I corrected it as well.

I've come across a bug in the indent/kotlin.vim file. The way it currently handles indentations does not account for C style/Javadoc comments like so:

/**
 * Comment
 * Stuff
 */
fun doSomething(): Int {
    
}

The problem:

When using the formatoptions r flag, Vim allows auto placement of comment blocks with a return line. For example, in normal Java, this will look like:

/**

Then pressing enter will give:

/**
 *

With the default configuration of the comments option in Vim. Kotlin's current indentation vim script ignores these settings, and places:

/**
*

This cannot be fixed unless the indentation script is modified. My current work around has been to remove the indentation script.

It would be great if vim could give you basic Kotlin syntax highlighting out-of-the-box. Any interest in sending a patch to add syntax into https://github.com/vim/vim/tree/master/runtime/syntax?

Triple-quoted strings in Kotlin do not do any escape processing so backslash-character should not be interpreted as an escape sequence.

E.g. my TeamCity config contains lines such as

        scriptContent = """tools\bin\make -C workdir myapp"""

...and the backslash-b is highlighted as if it is valid while backslash-m is highlighted as an error. Neither of these should be highlight.

I believe that the fix is to simply remove the ,ktSpecialChar,ktSpecialCharError bit from the end of the line in syntax/kotlin.vim for ktString start='"""' but I'm not sure if that's entirely correct.

I reference the information about "raw strings" on https://devtut.github.io/kotlin/strings.html#string-literals

Function name highlighting is implemented in both rust.vim and vim-cpp-enhanced-highlight, and rust.vim has highlighting for names of structs too, which is really nice (would be highlighting of class/interface/etc. names here). I'm not sure if this is wanted in this particular plugin, but I figured I'd throw it out there since it helps readability and makes things look nicer IMHO.

This could be implemented multiple ways too. For example, python-syntax only highlights the names of functions when they are defined, but not called (as far as I've noticed). I think always highlighting function names (on both calls and definitions) looks nicer, but of course opinions on this will vary.

How do you feel about adding support for appropriate makeprg into this plugin? Something like this should do:

:setlocal makeprg=java\ -cp\ .:/usr/local/Cellar/kotlin/1.3.10/libexec/lib/kotlin-stdlib.jar\ %:r:gs?^.?\\u&?Kt

( % filename :r remove extension gs?^.?\\u&? - capitalise first letter (hello - Hello) - same as in /^./\u&/gs Kt - add to the end )

This will cover scripts without specified package: :!java -cp .:/usr/local/Cellar/kotlin/1.3.10/libexec/lib/kotlin-stdlib.jar HelloKt

But sure this can be extended with something like :echo substitute(getline(1), ‘package ‘, ‘’, ‘’).

I'm not totally clear on how to get kotlin stdlib path. We can try to guess it or require user to set env variable to the kotlin install dir.

fun foo() {
    /*
    println()
    */
    <caret>

Press } at the caret position in the source above.

Expected result:

fun foo() {
    /*
    println()
    */
}

Actual result:

fun foo() {
    /*
    println()
    */
    }
