Increasing productivity

To increase productivity of IntelliJ IDEA, you can change settings that reside in the following locations (depending on your operating system):

  • On Windows systems:
    <IntelliJ IDEA installation folder>/bin/idea.exe.vmoptions
                    
    or
    <IntelliJ IDEA installation folder>/bin/idea64.exe.vmoptions
                    
  • On *NIX systems:
    <IntelliJ IDEA installation folder>/bin/idea.vmoptions
                    
    or
    <IntelliJ IDEA installation folder>/bin/idea64.vmoptions
                    
  • On OS X:

    Since version 12:
    The file /Applications/IntelliJ IDEA.app/bin/idea.vmoptions should be copied to

    ~/Library/Preferences/IntelliJIdeaXX/idea.vmoptions

Example. increasing heap size

For example, to increase IntelliJ IDEA heap size, you should copy the original .vmoptions file from /Applications/IntelliJ IDEA.app/bin/idea.vmoptions to ~/Library/Preferences/IntelliJIdeaXX/idea.vmoptions, then modify the -Xmx setting.

For the older versions, the settings are stored in:

                    /Applications/IntelliJ IDEA.app/Contents/Info.plist
                

Managing case of unicode literals

11.1+

IntelliJ IDEA allows defining whether non-ascii characters should use literals like '\u00AB' or '\00ab'.

This behavior is controlled by the system property idea.native2ascii.lowercase. By default, upper case characters are used.

If it is desirable to use lower case characters, do the following (depending on your platform)

  • 12.0+On Windows and *NIX: add the line
        idea.native2ascii.lowercase=true
    

    to the bin/idea.properties file, located under the product installation.

  • On OS X:

    Copy the file /Applications/IntelliJ IDEA.app/bin/idea.properties to ~/Library/Preferences/IntelliJIdeaXX/, open it for editing, and add the line

        idea.native2ascii.lowercase=true
    

    It is essential to create a copy, since the settings are replaced rather than added.

    For the older versions of IntelliJ IDEA, open for editing the file /Applications/IntelliJ IDEA.app/Contents/Info.plist, and add the following code:

        <key>idea.native2ascii.lowercase</key>
        <string>true</string>
    
    

    to the section <key>Properties</key> <dict> ... <dict>
