java_getset.vim

Vim file type plugin for the creation of Java getters and setters. This code was written in 2002 and I've not programmed in Java for about the same amount of time. However, I post the code here for anyone interested.

Description

This filetype plugin enables a user to automatically add getter/setter methods for Java properties. The script will insert a getter, setter, or both depending on the command/mapping invoked. Users can select properties one at a time, or in bulk (via a visual block or specifying a range). In either case, the selected block may include comments as they will be ignored during the parsing. For example, you could select all of these properties with a single visual block.

public class Test 
{ 
   // Start your selection here 
   private static int count; 

   /** The name */ 
   private String name; 

   /** The array of addresses */ 
   private String[] address; 
   // End your selection here 

   public static void main(String[] args) 
   { 
   } 
}

The script will also add the static modifier to the method if the property was declared as static. Array-based properties will get additional methods added to support indexing. In addition, if a property is declared final, it will not generate a setter for it. If a previous getter OR setter exists for a property, the script will not add any methods (under the assumption that you've manually added your own).

The getters/setters that are inserted can be configured by the user. First, the insertion point can be selected. It can be one of the following: before the current line / block, after the current line / block, or at the end of the class (default). Finally, the text that is inserted can be configured by defining your own templates. This allows the user to format for his/her coding style. For example, the default value for s:javagetset_getterTemplate is:

    /** 
     * Get %varname%. 
     * 
     * @return %varname% as %type%. 
     */ 
    %modifiers% %type% %funcname%() 
    {   
        return %varname%; 
    }

Where the items surrounded by % are parameters that are substituted when the script is invoked on a particular property. For more information on configuration, please see the section below on the INTERFACE.

Installation

Download the script from Vim's script repository or from this repository.
Copy the script to your ${HOME}/.vim/ftplugins directory and make sure its named java_getset.vim or java_something.vim where something can be anything you want.
(Optional) Customize the mapping and/or templates. You can create your own filetype plugin (just make sure its loaded before this one) and set the variables in there (i.e. ${HOME}/.vim/ftplugin/java.vim)

Interface

The following section documents the commands, mappings, and variables used to customize the behavior of this script.

Commands

:InsertGetterSetter Inserts a getter/setter for the property on the current line, or the range of properties specified via a visual block or x,y range notation. The user is prompted to determine what type of method to insert.

:InsertGetterOnly Inserts a getter for the property on the current line, or the range of properties specified via a visual block or x,y range notation. The user is not prompted.

:InsertSetterOnly Inserts a setter for the property on the current line, or the range of properties specified via a visual block or x,y range notation. The user is not prompted.

:InsertBothGetterSetter Inserts a getter and setter for the property on the current line, or the range of properties specified via a visual block or x,y range notation. The user is not prompted.

Mappings

The following mappings are pre-defined. You can disable the mappings by setting a variable (see the Variables section below). The default key mappings use the <LocalLeader> which is the backslash key by default ''. This can also be configured via a variable (see below).

<LocalLeader>p (or <Plug>JavagetsetInsertGetterSetter) Inserts a getter/setter for the property on the current line, or the range of properties specified via a visual block. User is prompted for choice.

<LocalLeader>g (or <Plug>JavagetsetInsertGetterOnly) Inserts a getter for the property on the current line, or the range of properties specified via a visual block. User is not prompted.

<LocalLeader>s (or <Plug>JavagetsetInsertSetterOnly) Inserts a getter for the property on the current line, or the range of properties specified via a visual block. User is not prompted.

<LocalLeader>b (or <Plug>JavagetsetInsertBothGetterSetter) Inserts both a getter and setter for the property on the current line, or the range of properties specified via a visual block. User is not prompted.

If you want to define your own mapping, you can map whatever you want to <Plug>JavagetsetInsertGetterSetter (or any of the other <Plug>s defined above). For example,

      map <buffer> <C-p> <Plug>JavagetsetInsertGetterSetter

When you define your own mapping, the default mapping does not get set, only the mapping you specify.

Variables

The following variables allow you to customize the behavior of this script so that you do not need to make changes directly to the script. These variables can be set in your vimrc.

no_plugin_maps Setting this variable will disable all key mappings defined by any of your plugins (if the plugin writer adhered to the standard convention documented in the scripting section of the VIM manual) including this one.

no_java_maps Setting this variable will disable all key mappings defined by any java specific plugin including this one.

maplocalleader By default, the key mappings defined by this script use <LocalLeader> which is the backslash character by default. You can change this by setting this variable to a different key. For example, if you want to use the comma-key, you can add this line to your vimrc:

        let maplocalleader = ','

b:javagetset_insertPosition This variable determines the location where the getter and/or setter will be inserted. Currently, three positions have been defined:

        0 - insert at the end of the class (default) 
        1 - insert before the current line / block 
        2 - insert after the current line / block

b:javagetset_getterTemplate, b:javagetset_setterTemplate, b:javagetset_getterArrayTemplate, b:javagetset_setterArrayTemplate These variables determine the text that will be inserted for a getter, setter, array-based getter, and array-based setter respectively. The templates may contain the following placeholders which will be substituted by their appropriate values at insertion time:

        %type%          Java type of the property 
        %varname%       The name of the property 
        %funcname%      The method name ("getXzy" or "setXzy") 
        %modifiers%     "public" followed by "static" if the property is static

For example, if you wanted to set the default getter template so that it would produce the following block of code for a property defined as public static String name:

        /** 
         * Get name. 
         * @return name as String 
         */ 
        public static String getName() { return name; }

This block of code can be produced by adding the following variable definition to your vimrc file.

        let b:javagetset_getterTemplate = 
          \ "\n" . 
          \ "/**\n" . 
          \ " * Get %varname%.\n" . 
          \ " * @return %varname% as %type%.\n" . 
          \ " */\n" . 
          \ "%modifiers% %type% %funcname%() { return %varname%; }"

The defaults for these variables are defined in the script. For both the getterTemplate and setterTemplate, there is a corresponding array-baded template that is invoked if a property is array-based. This allows you to set indexed-based getters/setters if you desire. This is the default behavior.
