1 bertho 1.14 CvsGraph 1.2.1, 24-Apr-2002
2 bertho 1.5 ===========================
3 bertho 1.1 CvsGraph creates a graphic representation of the revisions and branches in a
4     cvs/rcs repository. CvsGraph is inspired on the 'graph'-option from WinCVS. I
5     could not find something right away on the web and decided that it was time to
6     write a stand-alone version. I might have been doing some double work, but hey,
7     I like a hack.

11 bertho 1.5 New in this version
12     -------------------
13 bertho 1.14 - Implement a workaround for browsers that do not understand unordered
14     y-coordinates in the imagemap when generated upside down.
15    
16     - Fix the slowness of CvsGraph when parsing very large (typically -kb files)
17     by bypassing the parsing of the actual deltatext. On my machine (K6-2/500/256M
18     it makes a difference of 7.5s vs 0.04s on a 93MByte file, without counting
19     disk-overhead; with disk-overhead it takes 12.5s).
20     Downside is that the logentry cannot be expanded if the file is not parsed in
21     full (see below). Use option parse_logs to enable log-expansions.
22    
23     - Implemented logentry expansions using %l and %L. You must enable full parsing
24     (option parse_logs) for this to work.

28     Compiling
29     ---------
30 bertho 1.9
31 bertho 1.1 create directory:
32     $ cd /where/ever/you/want
33 bertho 1.14 $ tar xzf cvsgraph-1.2.1.tar.gz
34     $ cd cvsgraph-1.2.1
35 bertho 1.3 $ ./configure
36 bertho 1.1 $ make
37    
38     This should do the trick and you have an executable file 'cvsgraph' in the
39     current directory.
40    
41 bertho 1.9 NOTE: The GD library is required for CvsGraph to function. Get it from
42     http://www.boutell.com, compile it and use either --with-gd-lib=DIR
43     and --with-gd-inc=DIR to specify its location. You might also have
44     to use --with-z-inc, --with-z-lib and --with-png-inc, --with-png-lib
45     for gd versions 1.6 and higher.
46     If you build with static libgd (i.e. libgd.a) and already have
47     libpng.so and/or libjpeg6b.so (i.e. dynamic), then you might want to
48     try to trick configure into adding these libs to the tests by adding
49     commandline options '--with-png-lib=.' and '--with-jpeg-lib=.'.
50 bertho 1.11 If you have linked libgd with freetype, then you might also need
51     either --with-freetype-lib or --with-freetype2-lib.

54 bertho 1.12
55 bertho 1.1 Installing
56     ----------
57     Put the executable file 'cvsgraph' somewhere where you think it should go.
58     Normally this would be "/usr/local/bin" or "/usr/bin". The configuration file
59     ought to be put in "/usr/local/etc" or "/etc". The exact position can be
60     overriden on the commandline anyway. Edit the configuration file to your liking
61     and you should be all set.
62    
63    
64    
65     Running CvsGraph
66     ----------------
67     Do *NOT* execute the program directly from a webserver. Direct execution would
68     be very insecure. Make a wrapper cgi-script in php, perl, or whatever you
69 bertho 1.10 normally use. The easiest way is to get the ViewCVS package from their website
70     at http://viewcvs.sourceforge.net and follow the instructions.
71    
72     Alternately, you can hack the 'cvsweb' package to call CvsGraph. There are
73     several scripts and patches available from the CvsGraph homepage (see below for
74     address). However, the scripts are no longer maintained because ViewCVS has
75     native support now.
76 bertho 1.1
77 bertho 1.2 To generate an image do something like:
78 bertho 1.5 $ cvsgraph -r /home/to/repository -m module -o mygraph.png myfile.c,v
79 bertho 1.1
80     This generates a revison/branch image of the rcs file 'myfile.c,v' and puts it
81 bertho 1.5 into 'mygraph.png'. The '-r' option is the path to the repository *located and
82 bertho 1.1 accessible* on your filesystem. The '-m' is the module in the repository. Note
83     that the extension of the file ends with ",v".
84    
85 bertho 1.9 Just to make it clear: You cannot make images from a cvs-repository over the
86     internet as if you were using cvs. The repository files
87     must be on a locally mounted filesystem. However, you
88     can use cvsup or rsync to get a repository to your
89     local filesystem and make then image from there.
90    
91 bertho 1.1 Type 'cvsgraph -h' to get a full list of options. If the output is not given
92     (no '-o'), then the output is written to standard output.
93    
94 bertho 1.5 Please read the manual pages cvsgraph(1) and cvsgraph.conf(5) for more
95     information on execution and configuration.

99     Todo
100     ----
101     - do a better job in making a layout (auto moving branches and rubber banding
102 bertho 1.12 revision-connectors to make place). A start is made, but this is not very
103     functional yet.
104 bertho 1.1
105 bertho 1.11 - draw only a part or parts of the tree.
