The "Compare with" dialog

Revision as of 05:06, 30 May 2008 by Tomasz.Zarna.pl.ibm.com (Talk | contribs) (Must have)


The goal of this project is to provide a more flexible and user-friendly way to compare files inside the Eclipse environment. Currently, the Eclipse's "Compare With" feature has a few problems:

  • There is no easy way to compare files located outside the workspace with ones located inside (see bug 73923 for details).
  • To compare two or three files in the current workspace the user has to select them (using a ctrl-click) and choose the "Compare With"->"Each Other" option from a pop-up menu.

Both these issues can be solved by providing an UI element (possibly a dialog or a view) to which user can add two or three files and than invoke a compare editor from it.

This project is part of 2008 Google Summer of Code.

Must have

  • adding files for comparison by drag'n'dropping them from the Package Manager
  • adding files for comparison by "Open Resource"/"Open Type" dialogs
  • adding files for comparison by "Open file" dialog (for choosing files located outside the current workspace)
  • adding clipboard content for comparison

Should have

  • invoking folder compares from the dialog

Nice to have

  • invoking a compare editor by drag'n'dropping one file to another in the Package Manager

Community proposals

Feel free to add your comments and ideas.

  • Please also have a look at the "AnyEdit tools" plugin: http://andrei.gmxhome.de/anyedit/index.html
    It also adds several enhancement to the selection of to be compared artifacts (like clipboard, opened editor...), so maybe you can benefit from the ideas or work over there.
