     4Trac has a built-in functionality for visualizing “diffs” - changes to files.

    6 == The Changeset View ==
     6There are different kinds of ''change sets''.
     7Some can correspond to revisions made in the repositories,
     8others can aggregate changes made in several revisions,
     9but in the end, any kind of differences can be shown.

    8 When viewing a commited changeset, such as when clicking a changeset
    9 [wiki:TracLinks TracLink] or a changeset event-line in the
    10 [wiki:TracTimeline timeline], Trac will display what changes this current set of patches imposes.
     11The changeset view consists of two parts, the ''header''
     12and the ''diff views''.

    12 The changeset view consists of two parts, the '''header''' and the '''diff view'''.
    13 
    14 === Changeset Header ===
     14== Changeset Header ==
    1515
    1616The header shows an overview of the whole changeset.
     
    2222 * Files -- A list of files affected by this changeset
    2323
     24If more than one revision is involved in the set of changes being
     25displayed, the ''Timestamp'', ''Author'' and ''Message'' fields
     26won't be shown.
     27
    2428In front of each listed file, you'll find  a colored rectangle. The color
    2529indicates how the file is affected by the changeset.
     
    2832 * Red: Removed
    2933 * Yellow: Modified
     34 * Blue: Copied
     35 * Gray: Moved

    3137The color legend is located below the header as a reminder.

    33 === Diff View ===
     39== Diff Views ==
    3440
    3541Below the header is the main part of the changeset, the diff view. Each file is shown in a separate section, each of which will contain only the regions of the file that are affected by the changeset. There are two different styles of displaying the diffs: ''inline'' or ''side-by-side'' (you can switch between those styles using the preferences form):
    3642
    37  * The ''inline'' style shows the changed regions of a file underneath eachother. A region removed from the file will be colored red, an added region will be colored green. If a region was modified, the old version is displayed above the new version. Line numbers on the left side indicate the exact position of the change in both the old and the new version of the file.
    38  * The ''side-by-side'' style shows the old version of the left and the new version on the right (this will typically require more screen width than the inline style.) Added and removed regions will be colored in the same way as with the inline style (green and red, respectively), but modified regions will have a yellow background.
     43 * The ''inline'' style shows the changed regions of a file underneath each other. A region removed from the file will be colored red, an added region will be colored green. If a region was modified, the old version is displayed above the new version. Line numbers on the left side indicate the exact position of the change in both the old and the new version of the file.
     44 * The ''side-by-side'' style shows the old version on the left and the new version on the right (this will typically require more screen width than the inline style.) Added and removed regions will be colored in the same way as with the inline style (green and red, respectively), but modified regions will have a yellow background.
    3945
    4046In addition, various advanced options are available in the preferences form for adjusting the display of the diffs:
    4147 * You can set how many lines are displayed before and after every change
     48   (if the value ''all'' is used, then the full file will be shown)
    4249 * You can toggle whether blank lines, case changes and white space changes are ignored, thereby letting you find the functional changes more quickly

     52== The Different Ways to Get a Diff ==
     53
     54=== Examining a Changeset ===
     55
     56When viewing a repository check-in, such as when following a
     57changeset [wiki:TracLinks link] or a changeset event in the
     58[wiki:TracTimeline timeline], Trac will display the exact changes
     59made by the check-in.
     60
     61There will be also navigation links to the ''Previous Changeset''
     62to and ''Next Changeset''.
     63
     64=== Examining Differences Between Revisions ===
     65
     66Often you'll want to look at changes made on a file
     67or on a directory spanning multiple revisions. The easiest way
     68to get there is from the TracRevisionLog, where you can select
     69the ''old'' and the ''new'' revisions of the file or directory, and
     70then click the ''View changes'' button.
     71
     72=== Examining Differences Between Branches ===
     73
     74One of the core features of version control systems is the possibility
     75to work simultaneously on different ''Lines of Developments'', commonly
     76called “branches”. Trac enables you to examine the exact differences
     77between such branches.
     78
     79Using the '''View changes ...''' button in the TracBrowser allows you to enter
     80''From:'' and ''To:'' path/revision pairs. The resulting set of differences consist
     81of the changes that should be applied to the ''From:'' content in order
     82to get to the ''To:'' content.
     83
     84For convenience, it is possible to invert the roles of the ''old'' and the ''new''
     85path/revision pairs by clicking the ''Reverse Diff'' link on the changeset page.
     86
     87=== Checking the Last Change ===
     88
     89The last possibility for examining changes is to use the ''Last Change''
     90link provided by the TracBrowser.
     91
     92This link will take you to the last change that was made on that path.
     93From there, you can use the ''Previous Change'' and ''Next Change'' links
     94to traverse the change history of the file or directory.
