Add syntax highlighting and snippets to Java/JSP files in Atom.
Originally converted from the Java TextMate bundle.
Contributions are greatly appreciated. Please fork this repository and open a pull request to add snippets, make grammar tweaks, etc.
Simple test case:
class Test
{
public void test()
{
test ? new Object() : new Object();
}
}The colon and the second new are not tokenized properly.
Copy/paste the above snippet into Atom and set the grammar as Java.
class A
{
private int array[];
}In java there is a keyword "volatile", it works very similar to syncronized, but only in variables.
Syntax highlighting for Java ternary operator is confused when used with the 'new' keyword and strings that have ':' character in them.
((1==1) ? new Date().toString() + " : " : "");
The above example makes the first '"' character not start a string. Therefore '?' matches with the first ':' it sees. It also breaks the syntax highlighting for the rest of the file. Although the problem can be easily solved by getting 'new Date()' into paranthesis, this is still a valid Java code and should be highlighted correctly.
((1==1) ? new Date().toString() + " : " : "");Expected behavior: '?' should only match the first valid ':' character, which is the second one in my case.
Actual behavior: It matches the first one it sees instead.

// compare
method( new Foo()
{
void bar( int a, int b ) {
// ...
}
});
// with
method( new Foo() {
void bar( int a, int b ) {
// ...
}
});
}
}The first boolean is "primitive" as it should be, but the second one isn't:
Looks like words that aren't keywords, etc are colored yellow instead of white. I'm not sure if this is a language problem or a problem with Atom One - let me know if I should post this over there!
Brackets and parentheses aren't scoped, they are the same color as variables:
list[i] = (sum == n ? true : false);Sometimes they can be distinguished in an identifier class:
public static void main(String[] args) {
}But they still aren't scoped:
The resources part of the try-with-resources statement does falsely require a trailing semicolon.
class Main {
public static void main() {
try (Foo foo = bar) {
}
}
}Expected behavior:
The meta.try.resources.java scope ends at the closing parenthesis and the try body gets the scope meta.try.body.java.
Actual behavior:
The meta.try.resources.java scope does never end and the try body still has the scopes meta.try.resources.java and meta.definition.variable.java.

Support for try-with-resources was originally added in #80 after being reported in #79.
The Java Spec defines the syntax of this language element as:
TryWithResourcesStatement:
try ResourceSpecification Block [Catches] [Finally]
ResourceSpecification:
( ResourceList [;] )
ResourceList:
Resource {; Resource}
Resource:
{VariableModifier} UnannType VariableDeclaratorId = Expression
See: http://docs.oracle.com/javase/specs/jls/se8/html/jls-14.html#jls-14.20.3
Therefore the semicolon after the "ResourceList" is optional. Furthermore the resources in the try-with-resources can't be arbitrarily code (link it is currently the case), but have to be a special kind of assignment.
Relevant source code: grammars/java.cson L532
I would fix it myself but I have no time at the moment + few experience with atom grammars, but maybe i have some time to look into it in the future.
The keyword strictfp does not get recognized as a keyword, although it is a valid one.
strictfp as a modifierExpected behavior: Recognition as a keyword (i.e. syntax highlighting)
Actual behavior: It is treated as regular source code

Have to put the constructor after the method for it to be properly highlighted.
I'm trying to add syntax highlighting to the default word in code like this:
public interface Lion {
default void roar() {
// roar
}
}However, the only selectors available seem to be .meta.method.return-type. Is there any plan to add Java 8 stuff like this and maybe add the default word to something like .storage.modifier or something?
Using a constructor reference within a code block in .rst or .md files breaks syntax highlighting for everything after that code block. I do believe this is an issue with the java grammar, as I was able to reproduce it with both of the aforementioned languages.
A screenshot showing the faulty highlighting in a java code block within a .rst file can be found here.
The error only occurs on constructor references (SomeClass::new), normal method references (SomeClass::someMethod) work fine.
If there is an ampersand as a value, something you could have for example in an href attribute, then the syntax highlighting breaks, at least in 0.24.0
There's no scopes set on stuff in catch blocks. See this simple example:
class MyClass {
public static void main(String[] args) {
try {
} catch (Exception exception) {
}
}
}
I would find it beneficial if there were a scope set on everything within the parenthesis (Exception, andexception in my example). What would that scope be called?
Reproduction:
class Test {
public int a;
}put cursor at int and Editor: Log Cursor Scope:
(adding [] after int as to actually have a primitive array works as expected)
atom 1.16 on ArchLinux. See attached source file and screenshots
bug.zip
Currently the JSP expression language just includes the normal java syntax (See jsp grammars line 80), but actually JSP EL has a quit different syntax then Java.
See: JSP EL on tutorialspoint or the spec (probably a bit overkill)
A few exampel JSP EL snippets :
${foo eq bar}
${fn:contains(true, 'x') ? bar : 'foo'}
${bar mod 10 eq 0}
${bar('some longer string', bar())}
${param["username"]}
${fn:indexOf(pageContext.session.getAttribute('bar'), 'foo') eq -1}
This happend with all themes (Atom included).

I have noticed that commented a method after a constructor leaves it the usual color, i.e. it is not greyed out. I have tried with a fresh install on Arch Linux 64bit and the bug is still there.
Expected behavior:
Proper highlight is triggered when the object is not constructed right before, as you can see here.
Actual behavior:
When doing the two steps in one shot, the problem arises: as you can see .setAppName(...) is not grayed.
My system is Arch Linux 64bit (up-to-date).

See: atom/language-coffee-script#39
Per the discussion on the CoffeeScript language package, it makes sense to keep the various default Atom language packages consistent. So rather than this being given a class of variable.language it should be given a class of variable.language.this.
Currently, as of version 0.17.0 of the package, there is no javadoc highlight. I could not find option to enable it either. What do you think about adding this feature? Or have you considered adding it in the past? For example, language-scala supports highlighting, so we could just implement something very similar, I guess.
@50Wliu I would appreciate your feedback on this, thanks.
It would be helpful, if a command for do-while-loop exist =)
Hi there,
This is probably a long-existing issue, but it's the first time I use auto-indent and I suspect it's the language-java scheme that determines how auto-indent behaves in java files? If not, let me know.
This should illustrate the difference between blocks with brackets and those without:
Cheerio.
The syntax highlighting for JavaServer Pages is being thrown off by a JSTL string replace pattern that consists of an escaped single quote:
<c:set var="foo" value="${fn:replace(entry.name, '\\'', ''')}" />
<c:set var="bar" value="test" />The problem is with the '\\'' segment.
Expected behavior: [What you expect to happen]
The syntax highlighting rules should catch the mismatched single quotes and ignore them.
Actual behavior: [What actually happens]
The odd number of single quotes confuses the syntax highlighter, and it treats any successive lines in the file as being string values.

Hi,
java syntax coloring breaks for some floating point constants:
float foo = 0.1f; // okay
float bar = .1f; // not okayThe latter case leads to '1f' being highlighted in bright red.

}I'm trying to use the scopes for some parsing of the java file. However, it seems as members of a class does not get scope meta.definition.variable.java unless it is also defined inline:
Is this intended or a bug/oversight?
The comments inside the Enum declarations are not highlighted properly.
The syntax highlighting gets messed up when the number of arguments to a function is large. I am not sure if this is a language-java issue in particular. But this is what I mean:
There is nothing wrong with the code. It renders with no syntax errors on Eclipse.

}
Save the file, and open it with VS Code.
Observe. It'll take very long time to open and applying syntax highlight.

In dark solarized theme & ubuntu 14.04,
Most color used in under source code is just blue!
Better colored source codes make users better to get into code.

}
}To be specific,
in function signature,
scope returnType functionName (arguments)
are just blue color.
even import are all colored blue..
import pakagePath.function
make pakagePath and Function should be colored differently for user interface.
Even, className is colored blue.
Therefore, I suggest to change coloring policy for Java source code.
I opened a similar issue for JavaScript: atom/language-javascript#374
Frankly, I dont use Atom to edit Java code, I use Eclipse instead. Given the low number of issues here, either I am not alone, or you are very good... 😛
OK, let's repeat the gist of the previous issue:
Atom 1.7.3, Windows 7, although the latter is probably not relevant...
AFAIK, $ is part of the valid characters in identifiers, like underscore. Yet it is treated as a foreign punctuation character in many features of Atom.
Examples:
$log.I know that Sun recommended not to use $ in identifiers, keeping this usage for themselves, but yet it is a valid char, and should be treated as such.
