gtags.conf − configuration data for GNU GLOBAL
has configuration data for global(1),
gozilla(1), gtags(1) and htags(1). They
look for the following files in this order, and read from
the first one that exists and is readable.
(1) --gtagsconf file
(3) [project root]/gtags.conf
(4) [project root]/[objdir]/gtags.conf
[sysconfdir] is ´/usr/local/etc´ by default; you can change it by the --sysconfdir option of the configure script. [objdir] is ´obj´ by default; you can change it by GTAGSOBJDIR or MAKEOBJDIR.
Its syntax is similar to termcap(5) except for some extensions described later. A file includes one or more records. You should select a record using a label. Default label is ´default´. If GTAGSLABEL is set, its value is used. Please be aware the meaning of ´default´ is different from that of termcap(5).
with ´#´ are ignored. A record consists of one
or more fields separated by ´:´ and ends with a
newline. The first field must have a label name. Each field
of the rest has a variable definition. There are three types
in those variables.
Boolean: This type has no value; existence of variable means true else
Number: This type has a number value after ´#´.
String: This type has a string value after ´=´.
Most variables are relevant to string type.
If data includes ´:´ or newline, you need to quote it by ´\’. An empty field is permitted, but it doesn’t make sense.
When there is more than one definition, the previous one is adopted. Exceptionally, all values of skip, langmap and gtags_parser are adopted and connected respectively.
substitution similar to sh(1) is available. You can
refer to any string variable using ´$´ prefix.
For example, the following b has a value
Tc is a
special variable; it reads in definitions in another record.
It is similar to the tc of termcap(5). Its
syntax is as follows:
If only a label is given, tc is read from a record specified by the label in the same file. If @file is also given, tc is read from a record specified by the label in the specified file. File should be an absolute path, and should not include variables. Different from termcap(5), you can use tc anytime anywhere.
About variables for each command, please see each manual.
You can use the
following environment variables as a string variable. If
these variables are set then environment variables of the
same name are set before command execution.
variables are also available as a string variable. By
default, each of them has a directory path given by the
environment variables affect the execution of the commands.
If this variable is set, the value is used as a configuration file.
If this variable is set, the value is used as a label of the configuration file. The default is default.
