    deb-substvars

    
    
    

    SYNOPSIS

           substvars
    
    
    

    DESCRIPTION

           Before  dpkg-source,  dpkg-gencontrol  and  dpkg-genchanges write their
           control information (to the source control file  .dsc  for  dpkg-source
           and  to  standard  output for dpkg-gencontrol and dpkg-genchanges) they
           perform some variable substitutions on the output file.
    
           A variable substitution has the form ${variable-name}.  Variable  names
           consist of alphanumerics, hyphens and colons and start with an alphanu-
           meric. Variable substitutions are performed repeatedly until  none  are
           left; the full text of the field after the substitution is rescanned to
           look for more substitutions.
    
           After all the substitutions have  been  done  each  occurrence  of  the
           string  ${}  (which  is  not a legal substitution) is replaced with a $
           sign.
    
           While variable substitution is done on  all  control  fields,  some  of
           those fields are used and needed during the build when the substitution
           did not yet occur. That's why you can't use variables in  the  Package,
           Source and Architecture fields.
    
           Variable  substitution  happens on the content of the fields after they
           have been parsed, thus if you want a variable to expand  over  multiple
           lines  you  do  not  have to include a space after the newline. This is
           done implicitly when the field is output. For example, if the  variable
           ${Description}  is  set  to "foo is bar.${Newline}foo is great." and if
           you have the following field:
    
            Description: foo application
             ${Description}
             .
             More text.
    
           It will result in:
    
            Description: foo application
             foo is bar.
             foo is great.
             .
             More text.
    
           Variables can be set using the -V common option. They can be also spec-
           ified in the file debian/substvars (or whatever other file is specified
           using the  -T  option).  This  file  consists  of  lines  of  the  form
           name=value.   Trailing  whitespace on each line, blank lines, and lines
           starting with a # symbol (comments) are ignored.
    
           Additionally, the following standard variables are available:
    
                  The source package version (from the changelog file). This vari-
                  able is now deprecated as its  meaning  is  different  from  its
                  function,  please  use  the  source:Version or binary:Version as
                  appropriate.
    
           Installed-Size
                  The total size of the package's installed files. This  value  is
                  copied  into  the  corresponding  control file field; setting it
                  will modify the value of that field. If this variable isn't  set
                  dpkg-gencontrol  will  use  du -k debian/tmp to find the default
                  value.
    
           Extra-Size
                  Additional disk space used when the  package  is  installed.  If
                  this  variable  is  set  its  value  is  added  to  that  of the
                  Installed-Size variable (whether set  explicitly  or  using  the
                  default  value) before it is copied into the Installed-Size con-
                  trol file field.
    
           F:fieldname
                  The value of the output field fieldname (which must be given  in
                  the  canonical  capitalisation).  Setting these variables has no
                  effect other than on places where they are expanded  explicitly.
    
           Format The  .changes  file  format version generated by this version of
                  the source packaging scripts. If you set this variable the  con-
                  tents  of the Format field in the .changes file will change too.
    
           Newline, Space, Tab
                  These variables each hold the corresponding character.
    
           shlibs:dependencyfield
                  Variable settings with names  of  this  form  are  generated  by
                  dpkg-shlibdeps.
    
           dpkg:Upstream-Version
                  The upstream version of dpkg.
    
           dpkg:Version
                  The full version of dpkg.
    
           If a variable is referred to but not defined it generates a warning and
           an empty value is assumed.

    BUGS

           The point at which field overriding occurs compared to certain standard
           output field settings is rather confused.
