Frequentry Asked Questions about GLOBAL.
----------------------------------------------------------------------------
Q1. Htags(1) aborts by short of memory. Why? Any workaround?
% htags
Out of memory!
% _
A1. It seems that Perl4 leaks memory. If you use that version of perl,
then you had better to use Perl5. This works well.
----------------------------------------------------------------------------
Q2. Global(1) and btreeop(1) sometimes core dumps when using a large tag file.
Any workaround?
A2. Btree(3) core dumps with a certain data set.
Please apply the patches in this package. See ./dbpatches/README.
----------------------------------------------------------------------------
Q3. GLOBAL skip some functions.
For example, GLOBAL skip the function 'func' in this example.
#define M(a) static char *string = a;
M(a)
func() { <= GLOBAL skip func().
...
}
A3. GLOBAL cannot recognize that pattern, because M(a) seems to be
a function definition.
It should be follows.
#define M(a) static char *string = a
M(a); <= end with ';'
func() {
...
}
Otherwise, you can tell gtags(1) that by listing the macros in
'.notfunction' file in current directory.
[.notfunction]
+---------------
|M
|...
----------------------------------------------------------------------------
Q4. I have set up 'global.conf' to use emacs's ctags command with GLOBAL
but I cannot use htags.
% gtags
% htags
htags: GTAGS and GRTAGS not found. Please make them.
% ls G*
GPATH GTAGS
A4. Emacs's ctags cannot locate function referencies. So, gtags cannot make
GRTAGS tag file with it. With the result that you cannot use htags and
global's -r option.

Patch for btree(3)
------------------
Btree(3) core dumps on certain data sets.
if (your system == FreeBSD 2.2.6R or former)
needs this patch.
else if (your system == Debian GNU/Linux 1.3.1)
needs this patch.
else
I don't know.
Please apply patch files in this directory.
1. patch your btree(3) source code
% ls
patch.1.2 patch.1.3 patch.1.4
% set dir=`pwd` <- set current directory
% cd /usr/src/lib/libc/db <- your db source code directory
% cd btree <- btree library
% patch < $dir/patch.1.2 <- it must be in this order.
.
.
% patch < $dir/patch.1.3
.
.
% patch < $dir/patch.1.4
.
.
2. remake and install your db(3) library.
3. remake GLOBAL.
4. remake tag files because tag files are already corrupted.
I derived these patches from 'http://www.sleepycat.com/update/'.
Information is found on 'http://www.sleepycat.com/update/patch.185.html'.

.Sh NAME
.Nm gctags
.Nd create a tags file (special command for GLOBAL)
.Nd print cross reference list for gtags.
.Sh SYNOPSIS
.Nm gctags
.Op Fl BDFacderstuvwx
.Op Fl f Ar tagsfile
.Ar name ...
.Op Fl b
.Op Fl e
.Op Fl n
.Op Fl r
.Op Fl s
.Op Fl w
.Ar file ...
.Sh DESCRIPTION
.Nm Gctags
makes a tags file for
.Xr ex 1
print cross reference list for
.Xr gtags 1
from the specified C,
Pascal, Fortran,
.Tn YACC ,
lex, lisp and assembler sources.
A tags file gives the locations of specified objects in a group of files.
Each line of the tags file contains the object name, the file in which it
is defined, and a search pattern for the object definition, separated by
.Tn JAVA ,
and assembler source to standard output.
Each line of output contains the object name, the line number which it appears,
the file in which it is defined, and a line image separated by
white-space.
Using the
.Ar tags
file,
.Xr ex 1
can quickly locate these object definitions.
It's same with the output of
.Xr ctags 1
with -x option.
.Pp
Depending upon the options provided to
.Nm gctags ,
objects will consist of subroutines, typedefs, defines, structs,
enums and unions.
objects will consist of function definitions, function references and other
symbols.
This command is the default parser of GLOBAL source code tag system.
.Bl -tag -width Ds
.It Fl B
use backward searching patterns
.Pq Li ?...? .
.It Fl D
allow duplicate object names.
.It Fl F
use forward searching patterns
.Pq Li /.../
(the default).
.It Fl a
append to
.Ar tags
file.
.It Fl c
print with compact format. It is valid only with -x option.
.It Fl d
create tags for
.Li #defines
that don't take arguments;
.Li #defines
that take arguments are tagged automatically.
.It Fl b
force level 1 block to begin when reach a '{' at the first column. (C only)
.It Fl e
force a function to end when reach a '}' at the first column. (C source only)
.It Fl f
place the tag descriptions in a file called
.Ar tagsfile .
The default behaviour is to place them in a file called
.Ar tags .
force level 1 block to end when reach a '}' at the first column. (C only)
.It Fl n

braces inside
.Li #ifdef Ns 's

In a similar fashion, multiple line changes within a definition will
cause it to enter the last line of the object, rather than the first, as
the searching pattern. The last line of multiple line
