1 bertho 1.10 .TH "CvsGraph" "1" "1.2.1" "B. Stultiens" "CVS/RCS Utilties"
2 bertho 1.1 .SH "NAME"
3     cvsgraph \- A CVS/RCS repository grapher
4     .SH "SYNOPSIS"
5     \fBcvsgraph\fR [\fIoptions\fR] \fIfile\fR
6     .SH "DESCRIPTION"
7     \fBCvsGraph\fR generates images and imagemaps from CVS/RCS repository files.
8     .SH "OPTIONS"
9     .TP
10 bertho 1.5 \fB\-b\fR
11 bertho 1.6 Add a branch box at the end of the trunk too. This option negates the
12 bertho 1.7 \fBbranch_dupbox\fR setting from the configuration file.
13 bertho 1.5 .TP
14 bertho 1.1 \fB\-c\fR \fIfile\fR
15     Read alternate config from \fIfile\fR.
16     .TP
17     \fB\-d\fR \fIlevel\fR
18     Enable debug mode at \fIlevel\fR. The amount of information is determined by a
19     bitwise or of the following: 1=config lexer, 2=config parser, 4=rcsfile lexer,
20 bertho 1.6 8=rcsfile parser, 16=rcsfile structure. The \fIlevel\fR argument may be in
21     decimal, octal or hexadecimal format.
22 bertho 1.1 .TP
23     \fB\-h\fR
24     A brief description of possible options.
25     .TP
26     \fB\-i\fR
27     Generate an imagemap instead of an image.
28     .TP
29 bertho 1.7 \fB\-I\fR \fIfile\fR
30     Also write an imagemap to \fIfile\fR. This can be usefull if you want to
31     generate both image and imagemap simultaneously. This halves the total time
32     spent on accessing the repository file because it is parsed only once.
33     .br
34     However, keeping track of auto-generated files can be a bit of a hack if
35     used in http requests (unless you pass both image and html-file in one
36     http-stream).
37     .br
38     Note 1: most time is used for the image-drawing routines (actually libgd),
39     so you might want to think twice in CGI apps.
40     .br
41     Note 2: you can still use '\fB-o\fR' to specify an output file for the image.
42     And, if you also specify '\fB-i\fR', then you'll get two imagemaps, for
43     whatever purpose that might be.
44     .TP
45     \fB\-k\fR
46     Try to reduce the image size by adjusting inter\-revision spacing and moving
47 bertho 1.8 trunks more left. This options negates the \fBauto_stretch\fR setting from the
48 bertho 1.7 configuration file.
49     .TP
50 bertho 1.1 \fB\-M\fR \fIname\fR
51 bertho 1.7 Use \fIname\fR as imagemap name (has only effect in combination with
52     '\fB\-i\fR'). This option overrides \fBmap_name\fR in the configuration file.
53 bertho 1.1 .TP
54     \fB\-m\fR \fImod\fR
55     Use \fImod\fR as cvsmodule.
56 bertho 1.7 This option overrides \fBcvsmodule\fR in the configuration file.
57     .TP
58     \fB\-O\fR \fIcfg_option=value[;opt=val[...]]\fR
59     Set \fIcfg_option\fR to \fIvalue\fR. Multiple \fB-O\fR are allowed as well
60     as multiple options can be set simultaneously by separating them with ';'.
61     See \fBcvsgraph.conf(5)\fR for a detailed list of options.
62     See also \fBCONFIGURATION\fR below.
63 bertho 1.1 .TP
64     \fB\-o\fR \fIfile\fR
65     Output to \fIfile\fR. Otherwise, output is written to standard output.
66     .TP
67     \fB\-q\fR
68     Be quiet (i.e. no warnings)
69     .TP
70     \fB\-r\fR \fIpath\fR
71     Use \fIpath\fR as cvsroot.
72 bertho 1.7 This option overrides \fBcvsroot\fR in the configuration file.
73 bertho 1.5 .TP
74 bertho 1.6 \fB\-s\fR
75     Strip all untagged revisions from the tree. Only the first, last and each
76     tagged revision of each trunk will be shown. This will greatly reduce the size
77     of the generated image if you didn't tag everything (and are not interested in
78 bertho 1.7 all revisions). This option negates the \fBstrip_untagged\fR setting from the
79 bertho 1.6 configuration file.
80     .TP
81 bertho 1.7 \fB\-S\fR
82     Also strip the first revision in a branch if untagged and not a branchpoint.
83     This has only effect if \fBstrip_untagged\fR or option '\fB\-s\fR' is set.
84     The '\fB\-S\fR' option negates the \fBstrip_first_rev\fR from the configuration
85     file.
86     .TP
87 bertho 1.5 \fB\-u\fR
88 bertho 1.6 Draw the tree upside down (newest revision at the top). This option negates the
89 bertho 1.7 \fBupside_down\fR setting from the configuration file.
90 bertho 1.1 .TP
91     \fB\-V\fR
92     Print version and exit.
93     .TP
94     \fB\-[0\-9]\fR \fItxt\fR
95     Use \fItxt\fR for expansion
96     .SH "CONFIGURATION"
97 bertho 1.7 \fBCvsGraph\fR starts with reading a configuration file. If the '\fB\-c\fR'
98     option is given on the commandline, then it is read. Otherwise, \fBcvsgraph\fR
99     first looks for a configuration file in the current directory using
100     \fI./cvsgraph.conf\fR and, if not found, tries to open
101     \fI/usr/local/etc/cvsgraph.conf\fR. Defaults and commandline overrides
102     will be used if no configuration file can be opened. The format of the
103     configuration file is described in \fBcvsgraph.conf(5)\fR. Configuration
104     parameters entered on the commandline have always precedence over the
105     configuration file. Configuration options are processed in the following
106     order:
107     .br
108     - configuration file
109     .br
110     - '\fB-O\fR' commandline options
111     .br
112     - other commandline overrides (\fB-bkMmrSsu\fR)
113     .br
114     If you do not want to process any configurationfile, then you can set option
115     \'\fB-c /dev/null\fR', which will read an empty configuration file.
116     .PP
117 bertho 1.1 The location of a repository file is determined by the configuration parameters
118 bertho 1.7 \fBcvsroot\fR and \fBcvsmodule\fR and the respective commandline options
119     '\fB\-r\fR' and '\fB\-m\fR'. The \fBcvsroot\fR, \fBcvsmodule\fR and \fIfile\fR
120     are concatenated with separating '/' path\-separators forming the final
121     location:
122 bertho 1.1 .br
123     <cvsroot>/<cvsmodule>/\fIfile\fR
124     .br
125 bertho 1.7 No path\-separator is appended if \fBcvsroot\fR and \fBcvsmodule\fR are empty
126     strings. An error message is issued if the resulting path cannot be opend.
127     Note that \fBcvsgraph\fR does not atempt to check any validity of the path
128     components. This enables a user to open any file on the file\-system by setting
129     \fBcvsroot\fR and \fBcvsmodule\fR to empty strings.
130 bertho 1.1 .br
131     For example, \fIcvsgraph \-r '' \-m '' ../myfile,v\fR would try to open the
132 bertho 1.7 file \fI../myfile,v\fR. Note that a variety of possibilities yield the same
133     file and all have their advantages and drawbacks, which are mostly related to
134     the possible use of the parameters in text expansions.
135 bertho 1.9 .PP
136     If no \fIfile\fR is given on the commandline, then input is read from standard
137     input. This can make expansion strings somewhat strange looking, but they are
138     composed with the information available. If no input file was given, then the
139     input filename for expansion is set to \fB<stdin>\fR.
140    
141 bertho 1.1 .SH "OUTPUT"
142 bertho 1.7 The output generated by \fBcvsgraph\fR can be either an image (default) or and
143     HTML imagemap ('\fB\-i\fR' and '\fB-I\fR' options).
144 bertho 1.1 .br
145 bertho 1.7 Images can have several formats, depending on the capabilities of the gd
146     library on which the drawing is built. The configuration allows for GIF, PNG or
147     JPEG type images. Newer versions of gd do no longer support GIF and PNG will be
148     used instead.
149     .br
150     Generation of imagemaps conforms to the HTML standard and maps rectangular
151     regions of the image where revisions and branches are drawn. Additionally, an
152     extra rectangular region is generated between revisions to support diff
153     generation.
154 bertho 1.1 .SH "FILES"
155     .LP
156     .TP
157     \fI/usr/local/etc/cvsgraph.conf\fR
158     Configuration file read for default layout parameters.
159     .SH "AUTHOR"
160     \fBCvsGraph\fR is written and maintained by B. Stultiens.
