NAME
deb-substvars - Debian source substitution variablesSYNOPSIS
substvarsDESCRIPTION
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 alphanumeric. 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.
Variables can be set using the -V common option. They can be also specified 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:
- Arch
- The current build architecture (from dpkg --print-architecture).
- source:Version
- The source package version.
- source:Upstream-Version
- The upstream source package version, including the Debian version epoch if any.
- binary:Version
- The binary package version (which may differ from source:Version in a binNMU for example).
- Source-Version
- The source package version (from the changelog file). This variable 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 control 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 contents 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.SEE ALSO
