NAME

       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) [project root]/[objdir]/gtags.conf

       (5) $HOME/.globalrc

       (6) /etc/gtags.conf

       (7) [sysconfdir]/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).

       Lines starting 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 false.

       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.

Variable substitution

       Variable substitution similar to sh(1) is available.  You can refer to 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 reads in definitions in another record.  It is similar to the
       tc of termcap(5).  Its syntax is as follows:
       tc=label[@file]
       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.

CONFIGURATION

       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.
       GREP_COLOR
       GREP_COLORS
       GTAGSBLANKENCODE
       GTAGSCACHE
       GTAGSFORCECPP
       GTAGSGLOBAL
       GTAGSGTAGS
       GTAGSLIBPATH
       GTAGSLOGGING
       GTAGSTHROUGH
       GTAGS_OPTIONS
       HTAGS_OPTIONS
       MAKEOBJDIR
       MAKEOBJDIRPREFIX
       TMPDIR

       The following variables are also available as a string variable.  By default, each of them
       has a directory path given by the configure script.
       bindir
       datadir
       libdir
       localstatedir
       sysconfdir

ENVIRONMENT

       The following environment variables affect the execution of the commands.

       GTAGSCONF
              If this variable is set, the value is used as a configuration file.

       GTAGSLABEL
              If  this  variable  is set, the value is used as a label of the configuration file.
              The default is default.
