       cvsgraph.conf - CVS/RCS repository grapher configuration


       The  configuration  file  is  a  context free grammar where empty lines and whitespace are
       ignored. Comments start with '#' and everything until end of line is ignored.
       A configuration parameter is written as:
            <keyword> = <argument> ;

       Keywords are defined in PARAMETERS. The argument can be either numerical or string typed.

       Numbers may be entered as octal, decimal or hex as in  0117,  79  and  0x4f  respectively.
       Floating  point numbers contain a single '.', but must start with a digit. Integer numbers
       are automagically converted to floats if required.

       Strings are C-style strings, enclosed in double quotes in which characters may be  escaped
       with  '\'  and written in octal and hex escapes. Note that '\' must be escaped if it is to
       be entered as a character. Escapes recognized are '\[abfnrtv]', '\[xX][0-9a-fA-F]{2}'  and
       Some  strings  are expanded with printf like conversions which start with '%'. Not all are
       applicable at all times, in which case they will expand to nothing.
       Note that expansions of paths are available with and without trailing '/'. The distinction
       is  required  for  path construction to ensure that empty expansions will not redirect the
       path to root and no double '/' in a path is generated.

       %c     CVS root including a trailing '/' if non-empty

       %C     CVS root without trailing '/', regardless of how it was entered on the command line

       %m     CVS module including trailing '/' if non-empty

       %M     CVS module without trailing '/', regardless of how it was entered  on  the  command

       %f     filename without path (basename <name> functionality)

       %F     filename without path and with ",v" stripped (basename <name> ,v functionality)

       %p     path part of filename. This includes a trailing '/' if the path is non-empty

       %r     number of revisions

       %b     number of branches

       %%     literal '%'

       %R     the revision number (e.g. '')

       %P     previous revision number

       %B     the branch number (e.g. '1.2.4')

       %d     date of revision

       %a     author of revision

       %s     state of revision

       %l     The  log entry of the revision. You need to enable parse_logs for this to work. You
              may append an optional truncate length by writing '[num]'  (with  num  the  maximum
              length)  directly  after  %l.  If  no  truncation  is  specified,  then all will be
              expanded. Specifying a negative truncation length means  that  newlines  should  be
              replaced  by  spaces.  If  truncation  occurs,  then  "..."  will  be appended. The
              expansion is scanned  for  possible  HTML  entities  and  are  replaced  by  &#...;
              For example: "%l[25]" will expand up to 25 characters of the log.
              Note: This expansion is obsolete. Please use "%(%L%)"; see comment below.

       %L     Same as %l, but no HTML entity translations are performed.

       %t     current tag of branch or revision

       %0..%9 command-line argument -0 .. -9

              HTMLize  the  string  withing the parenthesis. This is useful to prevent a possible
              cross site scripting bug when expanding tags  into  the  map  generation.   For  an
              exploit,  you  need  to  have  an  attack  on  your CVS server, or you need to be a
              complete idiot to enter a tag with '<', '>' or '"' characters.
              Example:  a  string  "%(%t%)",  with  tag  ><script  xxx="..."><  will  expand   to
              &gt;&lt;script xxx=&#34;...&#34;&gt;&lt; and not into the execution of a script.
              Note:  This  method  is  preferred  to the %l expansion, because it is more generic
              solution (i.e. use "%(%L%)" for log expansions).

       Fonts are numbered 0..4 (as defined in libgd) where 0 =  tiny,  1  =  small,  2  =  medium
       (bold), 3 = large and 4 = giant.

       Colors  are  strings, similar to HTML type colors in the form "#rrggbb" with parts written
       in hex, where rr = red (00-ff), gg = green (00-ff) and bb = blue (00-ff).

       Colors  and  some  strings  can  also  be  defined  as  conditional  expressions  so  that
       revision/branch conditions can be repesented visually:
         color/string = [ "key" op "content" truecase falsecase ];
       Operator 'op' can be one of:

       =~     contained in regex

       =*     contained in regex, case insensitive

       !~     not contained in regex

       !*     not contained in regex, case insensitive

       <      less than string, timestamp or rev/branch number

       <=     less or equal than string, timestamp or rev/branch number

       >      greater than string, timestamp or rev/branch number

       >=     greater or equal than string, timestamp or rev/branch number

       ==     equal than string, timestamp or rev/branch number

       !=     not equal than string, timestamp or rev/branch number

       The 'content' is one of:
           * POSIX 1003.2 extended regular expression
           * timestamp in UTC format: YYYY[.MM[.DD[.hh[.mm[.ss]]]]]
           * revision or branch number

       The 'key' can be one of:

       state  State of the revision

       author The auther of a revision

       tag    both revision- and branch-tags

       date   date of the revision

       rev    numeric revision- or branch-number

       Both  'truecase'  and 'falsecase' can be either a (color-)string, as described above, or a
       new conditional expression.  Examples:
           rev_bgcolor = [ "state" =~ "dead" "#e08080" "#f0f0f0" ];
           branch_color= [ "rev" < "2.1.2" "#000000" [ "tag" =~ "XyZ.*" "#123456" "#654321" ] ];
           rev_idtext  = [ "state" == "dead" "Dead %R" "%R" ]
       Note that not all colors can be changed on the fly. For example, branch_color cannot be be
       changed  based  on  revision  identification (i.e. author, date or state). The color_bg is
       always unique and fixed (all expressions will evaluate to the  false  case).   Also,  only
       string  rev_text  and  rev_idtext can be conditional expressions as other do not make much
       sense to be dynamic.

       Booleans have three possible arguments: true, false and not. `Not' means inverse  of  what
       it  was (logical negation) and is represented by the value -1.  For the configuration file
       that means that the default value is negated.  However, the  not  possibility  is  a  very
       handy tool for command line overrides generated from (CGI) scripts.

       There are several reserved words besides of the keywords.  These additional reserved words
       expand to numerical values:
            false  = 0
            true   = 1
            not    = -1
       Alignment specifiers:
            left   = 0
            center = 1
            right  = 2
       Image specifiers:
            gif    = 0
            png    = 1
            jpeg   = 2
       Font specifiers:
            tiny   = 0
            small  = 1
            medium = 2
            large  = 3
            giant  = 4
       HTML level specifiers:
            HTML3  = 1
            HTML4  = 2
            XHTML  = 3


       cvsroot string
              The absolute base directory where the CVS/RCS repository can be found.  A '/'  will
              be appended to the string if it is not empty and does not contain a trailing '/'.
              Default is an empty string.

       cvsmodule string
              The  module  name  in the CVS/RCS repository. This is converted into a subdirectory
              name with a trailing '/'.
              Default is an empty string.

       color_bg color
              The background color of the image.
              Default is white ("#ffffff").

       transparent_bg boolean
              The background color of the image is to be the  transparent  color.  This  is  only
              useful for PNG images. Be sure to set color_bg to something reasonable to make sure
              that the image is viewable with programs that do not support transparency.
              Default is false.

       date_format string
              The strftime(3) format  string  for  date  and  time  representation  in  the  '%d'
              Default is "%d-%b-%Y %H:%M:%S".

       box_shadow boolean
              A boolean whether or not to draw a shadow for the boxes of revisions and branches.
              Default is false.

       upside_down boolean
              Draw  the  entire tree upside down if set. I.e. highest revisions are at the top of
              the image. See also cvsgraph(1) option '-u'.
              Default is false.

       left_right boolean
              Draw the entire tree from left to right instead of top down if set.   I.e.  highest
              revisions  are  at the right of the image. You can also draw the tree right to left
              when upside_down is set too.
              Default is false.

       strip_untagged boolean
              Omit all revisions that do not have tags and are not a branch point.  This  reduces
              the image-size, but can be confusing when looking for a specific revision. See also
              cvsgraph(1) option '-s'.
              Default is false.

       strip_first_rev boolean
              Also omit the first revision in a branch if it does not have  tags  and  is  not  a
              branch  point.  This has only effect if strip_untagged is set. See also cvsgraph(1)
              option '-S'.
              Default is false.

       auto_stretch boolean
              Try to stretch the inter-revision spacing to move the  trunks  more  to  the  left,
              effectively reducing the image's size. See also cvsgraph(1) option '-k'.
              Default is false.

       use_ttf boolean
              Enable  TrueType  rendering of strings using the FreeType interface of libgd.  Note
              that ttf rendering is significantly slower than libgd's bitmap fonts.
              Default is false.

       anti_alias boolean
              Enable antialias rendering of TrueType fonts. This has only effect  if  use_ttf  is
              set.  Enabling anti_alias gives very nice results.  However, that is at the expense
              of 8-bit vs. 4-bit colormap images, which can be a major drawback because the  size
              of 8-bit images is 3..4 times that of 4-bit images (with compressed PNG as output).
              Default is true.

       thick_lines number
              Set  the  thickness of connector lines between boxes. Normally, lines are drawn one
              pixel wide, but can look somewhat thin. Setting the thickness to  anything  over  5
              would  be  plain ugly (but hey, who is to debate taste :-).  Values less than 1 and
              over 11 are clipped.
              Default is 1.

       parse_logs boolean
              Enable the parsing of the entire ,v file to read the log-entries between revisions.
              This  is  necessary  for the %l expansion to work, but slows down parsing by a very
              large factor. You've been warned.
              Default is false.

       html_level number
              Set the compliance to different types of HTML. The generated image map is  slightly
              different  for  version  3.x, 4.x and XHTML. You can use the predefined identifiers
              (HTML3, HTML4 and XHTML) to set this value. Command line option '-x' overrides  the
              Default is HTML3 (3.x compatibility).

       branch_ttfont string

       branch_tag_ttfont string

       rev_ttfont string

       rev_text_ttfont string

       tag_ttfont string

       title_ttfont string

       msg_ttfont string
              Set  the  TrueType  font  face or filename for the individual elements. Gd's bitmap
              fonts are used as a fallback if the font cannot be found or contains errors.
              Default none.

       branch_ttsize float

       branch_tag_ttsize float

       rev_ttsize float

       rev_text_ttsize float

       tag_ttsize float

       title_ttsize float

       msg_ttsize float
              Set the TrueType font size for the individual elements. See also *_ttfont.
              Default 0.0.

       tag_font number
              The font used to draw tags in the revision boxes.
              Default is tiny.

       tag_color color
              The color used to draw tags in the revision boxes.
              Default is black ("#000000").

       tag_ignore string
              An extended regular expression as described in regex(7)  to  match  all  tags  that
              should  not  be displayed in the graph. Note that a tag will always be displayed if
              it matches the merge_from/merge_to expressions regardless to it being set to ignore
              Example: tag_ignore = "(test|alpha)_release.*";
              Default is empty (no matching occurs).

       tag_nocase boolean
              Ignore the case in regex matching in tag_ignore.
              Default is false.

       tag_negate boolean
              Negate the matching criteria of the tag_ignore setting. If set, tags that match the
              tag_ignore will be shown, instead of matches being ignored. In any case, tags  that
              match merge_from/merge_to expressions will never be suppressed.
              Default is false.

       tag_ignore_merge boolean
              If set, then tags matched with tag_ignore will no longer be considered for matching
              by merge_from and merge_to.
              Default is false.

       rev_font number
              Default is tiny.

       rev_color color
              The color of revision boxes, including the revision number.
              Default is black ("#000000").

       rev_bgcolor color
              Revision box background color. This is the interior fill of the box.
              Default is white ("#ffffff").

       rev_separator number
              Space between tags in revision boxes.
              Default is 0.

       rev_minline number
              The minimum vertical distance between revision boxes.
              Default is 0.

       rev_maxline number
              The maximum vertical distance between revision boxes.   This  has  only  effect  if
              auto_stretch is set to true (or option '-k' is specified).
              Default is 5 times rev_minline.

       rev_lspace number

       rev_rspace number

       rev_tspace number

       rev_bspace number
              Interior  spacing  in  revision  boxes of left, right, top and bottom respectively.
              Note that the left right spacing is not used  separately  because  text  is  center
              Default is 0.

       rev_idtext conditional string
              The revision ID or revision number in a revision box.
              Default is "%R".

       rev_text conditional string
              The additional text in a revision box under the revision number.
              Default is "%d".

       rev_text_font number
              The font of the additional text in a revision box under the revision number.
              Default is tiny.

       rev_text_color color
              The font color of the additional text in a revision box under the revision number.
              Default is black ("#000000").

       rev_maxtags number
              Limit  the  number of tags in a revision box. Old trees tend to have some revisions
              with extremely many tags attached, which would generate a huge  revision  box  when
              drawn.  Limiting  the  number  is  a  fair  solution.  Note that tag sorting is not
              specified in the rcsfile(7), but cvs(1) will normally have the newest tags  located
              before  older  ones.  Therefore, limiting the number of tags would most likely only
              affect older tags to be stripped.  However, no guarantees are given that a specific
              tag  is  present  when  the  limit  is  imposed.  An ellipsis (...) is shown in the
              revision box when the number of tags got truncated.
              Default is 0, meaning all tags shown.

       rev_hidenumber boolean
              If set, then no revision number is displayed in  the  revisionboxes.  This  reduces
              size for those graphs where the actual revision-number is irrelevant.
              Default is false.

       msg_font number
              The font used to draw error and warning messages at the bottom of the graph.
              Default is tiny.

       msg_color color
              The color used to draw error and warning messages.
              Default is black ("#000000").

       merge_color color
              The color of the lines to show merges.
              Default is black ("#000000").

       merge_front boolean
              The  merge  lines are drawn on top of the image if true. Otherwise, merge lines are
              drawn underneath.
              Default is false.

       merge_nocase boolean
              Ignore the case in regex matching in merge_from and merge_to.
              Default is false.

       merge_from string
              The merge_from is an extended regular expression as described in regex(7) and POSIX
              1003.2  (see  also  Single  Unix  Specification  at ). The
              matching tags describe source revisions of merges. Each match is subsequently  used
              in a search for the destination tag as described by the merge_to parameter.
              Note:  normal  string  rules apply. Therefore, all backslashes '\' must be escaped,
              e.g. "\." must be written as "\\.".
              Example: merge_from = "^from_(.*)";
              Default is empty (no matching occurs).

       merge_to string
              The merge_to is an extended regular expression with  a  twist.  All  subexpressions
              from  the merge_from are expanded into merge_to using %[1-9] (in contrast to \[1-9]
              for backreferences). Care is taken to escape the constructed expression. A  '$'  at
              the  end  of  the  merge_to  expression  can  be  important to prevent 'near match'
              references. Normally, you want the destination to be a good representation  of  the
              source. However, this depends on how well you defined the tags in the first place.
              Example: merge_to = "^merge_%1$";
              Above   example,   combined   with   the  merge_from  example  would  match  a  tag
              "from_BugFix_2002" to the merge-destination with tag "merge_BugFix_2002".
              Default is empty (no matching occurs).

       merge_findall boolean
              Normally, merge_from/merge_to will only find the first matching tag-combination and
              draw a line between them, If merge_findall is set, then all matching merge_tos will
              result in lines from the from-tag to the to-tag.
              Default is false.

       merge_arrows boolean
              Enable the use of arrows pointing to the merge destination.
              Default is true.

       merge_on_tag boolean
              Draw merge lines  originating  from/to  the  actual  tags  that  are  matched  when
              left_right is enabled. This improves the usability of the lines drawn but can under
              circumstances be difficult to visualize  without  revision  boxes  overlapping  the
              lines and arrows.
              Default is false.

       merge_cvsnt boolean
              Enable drawing of mergepoints as used by CVSNT.
              Default is true.

       merge_cvsnt_color color
              The color of the lines to show merges from mergepoints.
              Default is black ("#000000").

       arrow_length number
              Specifies the size of the arrow pointing to the merge destination.
              Default is arrow_width=3, arrow_length=12.

              Default is 0.

       branch_connect number
              Length of the vertical connector from a revision to the branch box.
              Default is 0.

       branch_dupbox boolean
              Add an extra branch box at the end of the  trunk.  Useful  for  upside  down  drawn
              trees.  If there are no commits on a branch, then no extra box is added, regardless
              of the setting of this option.
              Default is false.

       branch_fold boolean
              Fold branches that have no commits into one branch-box. This helps  to  reduce  the
              size of the overall image by a huge factor (5..10 in most cases). Many applications
              of CVS use many branches, but not all files  in  the  repository  change  for  each
              branch.  Especially  stable  files line .cvsignore or older code tend to accumulate
              many empty branches at one and the same revision. Folding these branches  into  one
              box reduces the width of these images considerably.
              Default is true.

       branch_foldall boolean
              Fold  all  empty  branches  that  sprout from the save revision in one box. If this
              option is not set, then multiple boxes will be created if the  empty  branches  are
              interspaced  with  ones that have revisions attached. When this option is set, then
              all empty branches will be collected and put into the box of  the  first  occurring
              empty branch on the revision's branch point.  Setting this option will reduce image
              size with interspaced commits to the a maximum.
              Default is false.

       branch_resort boolean
              Resort the branches according to the number of  revisions  they  have,  where  less
              revisions  will  stick  closer  to the sprouting trunk. This will reduce image size
              under circumstances where  many  branches  have  significant  different  number  of
              Default is false.

       branch_subtree string
              Reduce  the  tree  only  to include the subtree from the branch-number given in the
              argument. If the argument is a revision which is the root  of  branches,  then  all
              those  branches  will  be  shown. The argument can also be a symbolic tag (either a
              branch- or revision-tag). You normally would set this option from the command  line
              with the -O option for interactive flexibility.
              Example: branch_subtree = "1.2.4";
              Default is empty (all branches shown).

       title string
              The title of the image.
              Default is empty string.

       title_x number

       title_y number
              Position of title.
              Default is 0.

              Default is tiny.

       title_align number
              Horizontal alignment of the title.
              Default is left.

       title_color color
              The color of the title.
              Default is black ("#000000").

       margin_bottom number

       margin_left number

       margin_right number
              Margins of the image. Note: the title position is not affected by the margin.
              Default is 0.

       image_type number
              Image  types are available if they can be found in the gd library. Some versions of
              gd do not have gif, although newer version have  it  implemented  again.   CvsGraph
              will automatically generate png images if gif is not available.
              Default  is  dependent on availability and is prioritized in the order png, gif and

       image_quality number
              The quality of a jpeg image (1..100)
              Default is 100.

       image_compress number
              Set the compression level of png images  (-1..9).  Zero  means  no  compression.  A
              higher  number  means  higher  compression.  Minus  one selects the default library
              Default is -1.

       image_interlace boolean
              Write png and jpeg images in interlaced format. This enables progressive loading in
              your browser (if supported).
              Default is false.
