About JDarkRoom

JDarkRoom is a popular, simple full-screen text file editor with none of the usual bells and whistles that might distract you from the job in hand. If you are writing a speech, novel, essay, thesis or just need to be able to concentrate on your writing, then JDarkRoom may help you.

I have released JDarkRoom under the umbrella of CodeAlchemists. Please donate if you find this software useful - it encourages me to add features and fix bugs.

The development of JDarkRoom was heavily inspired by DarkRoom, an implementation of WriteRoom (which is a Mac-only application) for Windows, but DarkRoom requires the Microsoft .NET framework. I decided to create my own implementation in Java for those that prefer not to use .NET.

Once the program has fully downloaded, you should be able to double-click on it and it should run straightaway. If you download the JAR version, an alternative is to open a command prompt, navigate to the directory where you downloaded the program, then type
java -jar JDarkRoom.jar
Mac users: You should be able to double-click the downloaded ZIP file, open the JDarkRoom directory, then drag JDarkRoom to your Applications folder, or to the Dock.

Tips

  • AsusTek Eee users: Download the Linux version and follow the instructions below for Ubuntu Linux. JDarkRoom will work with Java 1.5, but you will need to specify
    force.full.screen=true
    as described below. ('suppress.native.look.and.feel=true' is not required)
  • Ubuntu Linux (or Xandros) users: JDarkRoom will work on Ubuntu/Xandros with Java 1.6. You will need to add the following line to your conf/jdarkroom.properties file (create one if it doesn't exist):
    suppress.native.look.and.feel=true
    If that doesn't work (and you're using Ubuntu Gutsy) try adding:
    force.full.screen=true
  • To override the default 'conf' directory location, set the JDARKROOM_CONF environment variable to (for example) ~/.jdarkroom and JDarkRoom will look for jdarkroom.properties in that directory instead of the default location
  • To switch between JDarkRoom and another program, use Alt-Tab (on Windows) or Command (Apple)-Tab (on an Apple Mac).
  • Another way to temporarily switch out of JDarkRoom is to try pressing Ctrl-K (may not work for all platforms).
  • To upgrade from an old version of JDarkRoom, just copy the new JDarkRoom file you downloaded over the old one.
  • Ctrl-backspace deletes the previous word
  • Press F9 to automatically recalculate font size and margins to something appropriate to your screen resolution
  • Any file specified on the command line will be opened at startup, e.g.
    java -jar JDarkRoom.jar /My JDarkRoom Files/writing.txt
    (as of version 12, they can contain spaces)
  • Backups (enabled by default) are auto-saved every 5 minutes. New files are saved to the directory shown on the settings screen and are called something like .jdarkroom-3765.tmp. Files that already have a filename are backed up in the same directory as the proper file, but are named .yourfilename.backup (for example). The filenames are prefixed with a dot so that they become 'hidden' on some platforms - to see them, you may need to type
    ls -a
  • To enable Emacs-style key bindings, you must shutdown JDarkRoom, add the following to your 'keymap.conf' file (in $HOME/.jdarkroom directory):
    Ctrl-F        = move cursor left
    Ctrl-B        = move cursor right
    Ctrl-N        = move cursor up
    Ctrl-P        = move cursor down
    Ctrl-A        = move cursor to beginning of line
    Ctrl-E        = move cursor to end of line
    
    .. then start up JDarkRoom.
  • To have JDarkRoom export your file to HTML format, you can use the 'export via Markdown' feature. In the Settings screen (F6), change the export converter to 'Markdown', then use Ctrl-F2 to export your file - give the exported file a name like 'myfile.html'. The syntax used is called 'Markdown' - learn more at http://daringfireball.net/projects/markdown/

If you find a bug with JDarkRoom, please report it via our bug tracker. It would help us greatly if you could attach debug information (JDarkRoom can automatically generate this for you via a button on the Settings screen (F6)) and a screenshot of the problem (again, automatically generated if you press Ctrl-F11).
