6.1.5 Directive Statements
Directive statements provide direction to the GateD configuration language parser about included
files and the directories in which these files reside. Directive statements are immediately acted
upon by the parser. Other statements terminate with a semi-colon (;), but directive statements
terminate with a newline. The two directive statements are:
- %directory "directory"
- Defines the directory where the include files are stored. When it is used, GateD looks
in the directory identified by pathname for any included files that do not have a fully
qualified filename i.e. do not begin with "/". This statement does not actually change the
current the directory, it just specifies the prefix applied to included file names.
- %include "filename"
- Identifies an include file. The content of the file is included in the gated.conf file at the
point in the gated.conf file where the %include directive is encountered. If the
filename is not fully qualified, i.e., it does not begin with "/", it is considered to be
relative to the directory defined in the %directory directive. The
%includedirective statement causes the specified file to be parsed completely before
resuming with this file. Nesting up to ten levels is supported. The maximum nesting
level may be increased by changing the definition of FI_MAX in parse.h.
In a complex environment, segmenting a large configuration into smaller, more easily understood
segments might be helpful, but one of the great advantages of GateD is that it combines the
configuration of several different routing protocols into a single file. Segmenting a small file
unnecessarily complicates routing configurations.
