    v1 v2  
    44Trac has a built-in functionality for visualizing “diffs” - changes to files. 
    55 
    6 There are different kinds of ''change sets''.  
    7 Some can correspond to revisions made in the repositories, 
    8 others can aggregate changes made in several revisions,  
    9 but in the end, any kind of differences could be shown. 
     6When viewing a repository check-in, such as when following a 
     7changeset [wiki:TracLinks link] or a changeset event in the  
     8[wiki:TracTimeline timeline], Trac will display the exact changes 
     9made by the check-in. 
    1010 
    11 The changeset view consists of two parts, the ''header''  
    12 and the ''diff views''. 
     11The changeset view consists of two parts, the ''header'' and the ''diff views''.

    1413== Changeset Header == 
     
    2120 * Message -- A brief description from the author (the commit log message) 
    2221 * Files -- A list of files affected by this changeset 
    23  
    24 If more than one revision is involved in the set of changes being 
    25 displayed, the ''Timestamp'', ''Author'' and ''Message'' fields  
    26 won't be shown. 
    2722 
    2823In front of each listed file, you'll find  a colored rectangle. The color 
     
    4641In addition, various advanced options are available in the preferences form for adjusting the display of the diffs: 
    4742 * 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) 
    4943 * 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  
    56 When viewing a repository check-in, such as when following a 
    57 changeset [wiki:TracLinks link] or a changeset event in the  
    58 [wiki:TracTimeline timeline], Trac will display the exact changes 
    59 made by the check-in. 
    60  
    61 There will be also navigation links to the ''Previous Changeset'' 
    62 to and ''Next Changeset''. 
    63  
    64  
    65 '''Note: all of the following will only be available in Trac [milestone:0.10]''' 
    66  
    67 === Examining Differences Between Revisions === 
    68  
    69 A very frequent need is to look at changes made on a file  
    70 or on a directory spanning multiple revisions.  
    71 The easiest way to get there is from the TracRevisionLog,  
    72 where one can select the '''old''' and the '''new''' revisions 
    73 of the path being examined, and then click the ''View changes'' 
    74 button. 
    75  
    76 === Examining Arbitrary Differences === 
    77  
    78 One of the main feature of source configuration management 
    79 systems is the possibility to work simultaneously on alternate 
    80 ''Lines of Developments'', or ''branches''.  
    81 The evolution of branches are often made in parallel, making it 
    82 sometimes difficult to understand the exact set of differences  
    83 between alternative versions. 
    84  
    85 This is where Trac comes to the rescue:  
    86 the '''View changes ...''' button in the TracBrowser 
    87 leads to a form permitting the selection of arbitrary 
    88 ''From:'' and ''To:'' path/revision pairs. 
    89  
    90 The resulting set of differences consist in the changes  
    91 that should be applied to the ''From:'' content in order 
    92 to make it look like the ''To:'' content. 
    93  
    94 For convenience, it is possible to invert the roles 
    95 of the '''old''' and the '''new''' path/revision pairs 
    96 by clicking the ''Reverse Diff'' link on the changeset page. 
    97  
    98 === Checking the Last Change === 
    99  
    100 The last possibility for looking at changes is  
    101 to have a quick look on the ''Last Change'' while 
    102 browsing a file or a directory.  
    103  
    104 This shows the last change that happened on that path. 
    105 The links ''Previous Changeset'' and ''Next Changeset'' 
    106 are replace by links to ''Previous Change'' and ''Next Change'', 
    107 which makes it really convenient to traverse the change history 
    108 of a specific file or directory. 
    109 This view of a changeset, restricted to a specific path, 
    110 is called ''restricted changeset''. 
    111  
    112 Of course, if one is doing that on the root of the 
    113 repository, there will be no path restriction 
    114 and the full changeset will be shown.
