gtags.conf — configuration data for GNU GLOBAL

Synopsis

´gtags.conf´
´~/.globalrc´

Description

´gtags.conf´ 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
(2) $GTAGSCONF
(3) [project root]/gtags.conf
(4) $HOME/.globalrc
(5) /etc/gtags.conf
(6) [sysconfdir]/gtags.conf

The format is almost similar to termcap(5) except for some extensions described later. The 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 of the meaning of 'default' it is different from one of termcap(5).

Lines starting with '#' are ignored. A record consists of one or more fields sepalated 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. (1) boolean: This type has no value; existence of variable means true else false. (2) number: This type has a number value after '#'. (3) string: This type has a string value after '='. Most variables are relevant to string type.

If data includes ':' or newline, you need quote it by '\'. An empty field is permitted, but it doesn't make sense.

Variable substitution

Variable substitution similar to sh(1) is available. You can refer any string variable using '$' prefix. For example, the following b has a value 'XYZ'.

:a=Y:b=X${a}Z:

Including another record

Tc is a special variable; it read in definitions in another record. It is similar to the tc of termcap(5). Syntax is as follows:

tc=label[@file]

If only a label is given, tc read from a record specified by the label in the same file. If '@file' is also given, tc read from a record specified by the label in the specified file. Different from termcap(5), you can use tc anytime anywhere.
