This is a mirror of http://www.vim.org/scripts/script.php?script_id=1785
|
||||
|
||||
This is javacomplete, an omni-completion script of JAVA language for vim 7.
|
||||
|
||||
It includes javacomplete.vim, java_parser.vim, Reflection.java, and
|
||||
javacomplete.txt
|
||||
|
||||
Features:
|
||||
- List members of a class, including (static) fields, (static) methods and ctors.
|
||||
- List classes or subpackages of a package.
|
||||
- Provide parameters information of a method, list all overload methods.
|
||||
- Complete an incomplete word.
|
||||
- Provide a complete JAVA parser written in Vim script language.
|
||||
- Use the JVM to obtain most information.
|
||||
- Use the embedded parser to obtain the class information from source files.
|
||||
- Tags generated by ctags can also be used.
|
||||
- JSP is supported, Builtin objects such as request, session can be recognized.
|
||||
The classes and jar files in the WEB-INF will be appended automatically to classpath.
|
||||
|
||||
|
||||
Requirements:
|
||||
It works on all the platforms where
|
||||
- Vim version 7.0 and above
|
||||
- JDK version 1.1 and above
|
||||
existed
|
||||
|
||||
Input context:
|
||||
It recognize nearly all kinds of Primary Expressions (see langspec-3.0)
|
||||
except for "Primary.new Indentifier". Casting conversion is also supported.
|
||||
Samples of input contexts are as following: ('|' indicates cursor)
|
||||
(1). after '.', list members of a class or a package
|
||||
- package.| subpackages and classes of a package
|
||||
- Type.| static members of the 'Type' class and "class"
|
||||
- var.| or field.| members of a variable or a field
|
||||
- method().| members of result of method()
|
||||
- this.| members of the current class
|
||||
- ClassName.this.| members of the qualified class
|
||||
- super.| members of the super class
|
||||
- array.| members of an array object
|
||||
- array[i].| array access, return members of the element of array
|
||||
- "String".| String literal, return members of java.lang.String
|
||||
- int.| or void.| primitive type or pseudo-type, return "class"
|
||||
- int[].| array type, return members of a array type and "class"
|
||||
- java.lang.String[].|
|
||||
- new int[].| members of the new array instance
|
||||
- new java.lang.String[i=1][].|
|
||||
- new Type().| members of the new class instance
|
||||
- Type.class.| class literal, return members of java.lang.Class
|
||||
- void.class.| or int.class.|
|
||||
- ((Type)var).| cast var as Type, return members of Type.
|
||||
- (var.method()).| same with "var.|"
|
||||
- (new Class()).| same with "new Class().|"
|
||||
|
||||
(2). after '(', list matching methods with parameters information.
|
||||
- method(|) methods matched
|
||||
- var.method(|) methods matched
|
||||
- new ClassName(|) constructors matched
|
||||
- this(|) constructors of current class matched
|
||||
- super(|) constructors of super class matched
|
||||
Any place between '(' and ')' will be supported soon.
|
||||
Help information of javadoc is not supported yet.
|
||||
|
||||
(3). after an incomplete word, list all the matched beginning with it.
|
||||
- var.ab| subset of members of var beginning with `ab`
|
||||
- ab| list of all maybes
|
||||
|
||||
(4). import statement
|
||||
- " import java.util.|"
|
||||
- " import java.ut|"
|
||||
- " import ja|"
|
||||
- " import java.lang.Character.|" e.g. "Subset"
|
||||
- " import static java.lang.Math.|" e.g. "PI, abs"
|
||||
|
||||
(5). package declaration
|
||||
- " package com.|"
|
||||
|
||||
The above are in simple expression.
|
||||
(6). after compound expression:
|
||||
- PrimaryExpr.var.|
|
||||
- PrimaryExpr.method().|
|
||||
- PrimaryExpr.method(|)
|
||||
- PrimaryExpr.var.ab|
|
||||
e.g.
|
||||
- "java.lang . System.in .|"
|
||||
- "java.lang.System.getenv().|"
|
||||
- "int.class.toString().|"
|
||||
- "list.toArray().|"
|
||||
- "new ZipFile(path).|"
|
||||
- "new ZipFile(path).entries().|"
|
||||
|
||||
(7). Nested expression:
|
||||
- "System.out.println( str.| )"
|
||||
- "System.out.println(str.charAt(| )"
|
||||
- "for (int i = 0; i < str.|; i++)"
|
||||
- "for ( Object o : a.getCollect| )"
|
||||
|
||||
|
||||
Limitations:
|
||||
The embedded parser works a bit slower than expected.
|
||||
|
||||
TODO:
|
||||
- Improve performance of the embedded parser. Incremental parser.
|
||||
- Add quick information using balloonexpr, ballooneval, balloondelay.
|
||||
- Add javadoc
|
||||
- Give a hint for class name conflict in different packages.
|
||||
- Support parameter information for template
|
||||
- Make it faster and more robust.
