+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.

- Netscape Navigator, Internet Explorer and so on. But some browsers
- cannot treat framed index. Then select '[no frame version is here]'.
-

+
+ Move the mouse cursor to a function name and click the middle button.
+ You will then go to the function's definition, or to its references,
+ depending on the context. In 'GTAGS SELECT MODE', move the mouse cursor
+ to a line and click the center button.
+
+ To return to the previous position, click the right button.
+
+4. Hypertext generator
+
+4.1. Features
+
+ o Htags makes hypertext from C, Yacc and Java source files.
+ o Once the hypertext is generated, you need nothing other than a WWW browser.
+ o You can move the hypertext to anywhere. It is independent of the source code.
+ o You can use all of your browser's functions, such as search,
+ history, bookmark, save, frames, windows.
+
+4.2. Preparation
+
+ At first, you must ensure that you have a lot of disk space. Hypertext
+ needs a great amount of disk space. For example, the source code
+ of FreeBSD kernel needs:
+
+ source code(/usr/src/sys) 14.0MB
+
+ GTAGS 1.5MB
+ GRTAGS 8.0MB
+ GSYMS 12.0MB
+ HTML/ 55MB(!!!)
+ -------------------------------------------------
+ total 77MB
+
+ Please do the following:
+
+ (at your source directory)
+ % gtags <- make the tag database(GTAGS,GRTAGS,GSYMS)
+ % htags <- make the hypertext(HTML/)
+
+ Then you will find an 'HTML' subdirectory in the current directory.
+
+4.3. Usage
+
+ Please start a web browser like this:
+
+ % lynx HTML/index.html
+
+ You will understand the usage by looking at the examples.
+
+ You can move the HTML directory to anywhere. It is independent of the
+ source code.
+
+4.4. Making hypertext of the kernel
+
+ If you would like to make hypertext of the FreeBSD kernel source, it is
+ convenient to use the systags script in this package.
+
+ % cd /usr/src/sys
+ % systags
+ then
+
+ % netscape HTML/index.html
+
+ You can use following functions with systags:
+
+ o An input form for a dynamic index.
+ (this reqires you to set up an httpd server for the CGI program.)
+ o Unlimited nested index.
+
+ Of course, you can use the above functions without systags. Please
+ see gtags(1) and htags(1).
+
+4.5. Gozilla
+
+ If you use Netscape Navigator, you can control the browser from the command
+ line by using gozilla(1).
+
+ % gtags
+ % htags
+ % global -x fork
+ fork 60 kern/kern_fork.c fork(p, uap, retval)
+ % gozilla +60 kern/kern_fork.c
+ %
+
+ Then you can see the hypertext specified around the fork function directly
+ on Netscape Navigator. If the browser has not been loaded, gozilla loads it.
+
+ If you use another browser like lynx, try this:
+
+ % gozilla -b lynx +60 kern/kern_fork.c
+
+ or
+
+ % setenv BROWSER lynx
+ % gozilla +60 kern/kern_fork.c
+
+ You can send a remote command to Netscape Navigator too. Try this:
+
+ % gozilla -C pagedown
+ % gozilla -C pageup
+
+ The remote commands are undocumented, but you can see the hint in the
+ resource file (Netscape.ad).
+
+ NOTES:
+ Netscape Navigator is a registered trademark of Netscape Communications
+ Corporation in the United States and other countries.
+
+
+5. Elvis using global
+
+Elvis 2.1 has new "tagprg" and "tagprgonce" variables for
+running an external tag search program. You can use them with GLOBAL.
+
+5.1. Features
+
+ o The tag function of elvis+GLOBAL can locate not only function definitions
+ but also function references.
+ o Elvis+GLOBAL allows duplicate tag entries.
+ o Elvis+GLOBAL can understand POSIX regular expressions
+ as a tag name for the search.
+ o Symbol search and pattern search are available.
+ o Mouse events are supported.
+
+5.2. Preparation
+
+ First, do the preparation of global. (Please see "1.2. Preparation").
+
+ Second, start elvis and execute 'set tagprg="global -t $1"' like this.
+
+ % elvis
+ ~
+ ~
+ ~
+ ~
+ ~
+ ~
+ :set tagprg="global -t $1"
+
+5.3. Basic usage
+
+ o To go to func1, you can say
+
+ :tag func1
+
+ It seemes the same as original elvis, but elvis execute 'global -t func1'
+ internally and read it instead of tags file.
+
+ o To go to the referenced point of func1, add -r option.
+
+ :tag -r func1
+
+ Elvis executes command like 'global -t -r func1' internally.
+
+ o To go to any symbols other than function, try this.
+
+ :tag -s lbolt
+
+ o To go to any strings other than symbols, try this.
+
+ :tag -g Copyright
+
+ o When using -r, -s or -g, you had better to use browse command.
+
+ :browse -r fork
+
+ It brings a following selection list. You can select tag and go to
+ the point.
+
+ Browse -r fork (2 matches)
+ +----------------+----------------+-------------------------------
+ | TAG NAME | SOURCE FILE | SOURCE LINE
+ +----------------+----------------|-------------------------------
+ |fork |ux/linux_misc.c | (line 565)
+ |fork |ern/init_main.c | (line 191)
+ +----------------+----------------+-------------------------------
+
+ o To get list of functions in a file, use -f command.
+
+ :browse -f main.c # locate functions in main.c.
+
+ o Other tag commands are also available:
+
+ <control-]> - go to the definition of current token.
+ <control-T> - return to the most recent tag context.
+ ":tag" - without argment, go to the next tag.
+ ":pop" - return to the most recent tag context.
+ ":stack" - display the tags stack.
+ ":stag" - creates a new window and moves its cursor to the
+ tag's definition point.
+ ":sbrowse" - same with 'browse' but show in a new window.
+
+5.4. Applied usage
+
+ o You can use POSIX regular expressions.
+
+ :tag ^put_ # locate functions start with 'put_'.
+
+ :browse -g 'fseek(.*L_SET)' # locate fseek() using L_SET argment.
+
+ o You can browse functions list of many files.
+
+ :browse -f *.c # locate functions in *.c.
+
+ o You can browse project files which includs specified pattern.
+
+ :browse -P ^vm/ # under vm/ directory.
+ :browse -P \.h$ # all include files.
+ :browse -P init # files including 'init'
+
+ o You can use mouse to select tag.
+
+ +----------------+----------------+-------------------------------
+ | TAG NAME | SOURCE FILE | SOURCE LINE
+ +----------------+----------------|-------------------------------
+ |fork |ux/linux_misc.c | (line 565)
+ |fork |ern/init_main.c | (line 191)
+ +----------------+----------------+-------------------------------
+
+ Please select tag name with mouse cursor and double click on the left
+ button and you go to the tag's point.
+ In source screen, also select function name and double click on the
+ left button and you can go to the point that the function is defined.
+ To come back, double click on the right button.
+
+A. Other topics
+
+A.1. How to plug in a parser
+
+ You can use a plugged-in parser. Copy global.conf to /etc/global.conf
+ or $HOME/.globalrc.
+
+ For example, if you would like to use ctags based on etags (included
+ by Emacs),
+
+ % cd /<emacs source directory>/lib-src
+ % make ctags
+ # cp ctags /usr/local/bin/ctags-emacs
+ % setenv GTAGSLABEL ctags-emacs <- see global.conf
+ % gtags
+ % ls G*
+ GPATH GTAGS
+
+ Or if you would like to use exuberant ctags (included by Vim editor),
+
+ % cd /<vim source directory>/src/ctags
+ % cp Makefile.unix Makefile
+ % make
+ # cp ctags /usr/local/bin/ctags-exuberant
+ % setenv GTAGSLABEL ctags-exuberant <- see global.conf
+ % gtags
+ % ls G*
+ GPATH GTAGS
+
+ GRTAGS and GSYMS don't exist, simply because these parsers don't support
+ the -r option and -s option like gctags(1) does.
+ All plugged-in parsers must print tag information to standard output
+ in the same style as 'ctags -x', ie.:
+
+ [1] [2] [3] [4]
+ ----------------------------------------------------------------
+ main 20 ./main.c main(argc, argv) /* xxx */
+
+ [1] tag name
+ [2] line number the tag appeared
+ [3] path name. It must be equal to argment path name.
+ [4] line image
+
+ Otherwise, you can make a suitable wrapper for the pug-in parser.
+
+A.2. Compact format.
+
+ You can save disk space with the compact format. The compact format
+ needs source files.
+
+ o To specify the use of the compact format on the command line,
+ add the -c option:
+
+ % gtags -c
+
+ o To specify the use of the compact format in the configuration file:
+
+ +----------------------------
+ |...
+ |default:\
+ | format=compact:...
+
+ o If you will publish hypertext generated by htags then use the -c option
+ of htags too:
+
+ % htags -c
+
+ With the -c option, htags makes gzipped hypertext.
+ You need to set up an HTTP server so that gzipped files can be read
+ (see 'HTML/.htaccess.skel').
+
+
+ Example:
+
+ Standard Compact Compressed rate
+ -------------------------------------------------------
+ GTAGS 1744896 bytes 720896 bytes -59%
+ GRTAGS 10133504 bytes 1409024 bytes -86%
+ GSYMS 11911168 bytes 9306112 bytes -22%
+
+ Standard Compact Compressed rate
+ -------------------------------------------------------
+ HTML/ 56618 kbytes 15219 kbytes -73%
+
+A.3. Incremental updating
+
+ Modifying some source files, you need not remake whole tag files.
+ Instead, you can use incremental updating facility (-i option).
- o mouse command is avalable.
+ % gtags
+ % cd kern
+ % vi tty.c # modify tty.c.
+ ...
+ :wq
+ % global -vi # -v means verbose.
+ [Sun Dec 6 16:27:47 JST 1998] Gtags started
+ Tag found in '/usr/src/sys'.
+ Incremental update.
+ Updating tags of 'kern/tty.c' ...GTAGS..GRTAGS..GSYMS.. Done.
+ Global databases have been modified.
+ [Sun Dec 6 16:28:30 JST 1998] Done.
+ % global -vi # try again.
+ [Sun Dec 6 16:28:48 JST 1998] Gtags started
+ Tag found in '/usr/src/sys'.
+ Incremental update.
+ Global databases are up to date. # do nothing.
+ [Sun Dec 6 16:28:52 JST 1998] Done.
- If you use X version emacs, try this.
- (But xemacs doesn't work well. I don't know why.)
+A.4. Plans for the furture
- Move mouse cursor to a function name and click center button. And you
- will go to function's definition or references depending on the context.
- In 'GTAGS SELECT MODE', move mouse cursor to a line and click center
- button.
+ Please see GLOBAL home page.
- To return to the previous position, click right button.
+ <http://wafu.netgate.net/tama/unix/global.html>

-And of course, I'm grateful to all excellent tools (vi, emacs, perl, C, db,
-mozilla ...) and its authors.

+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 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.

-.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

-needed at the current directory. (C source only)
+needed at the current directory. (C and Java source only)
+By default, locate function definitions.
.It Fl s
-collect symbols except for functions.
-.It Fl t
-create tags for typedefs, structs, unions, and enums.
-.It Fl u
-update the specified files in the
-.Ar tags
-file, that is, all
-references to them are deleted, and the new values are appended to the
-file. (Beware: this option is implemented in a way which is rather
-slow; it is usually faster to simply rebuild the
-.Ar tags
-file.)
-.It Fl v
-An index of the form expected by
-.Xr vgrind 1
-is produced on the standard output. This listing
-contains the object name, file name, and page number (assuming 64
-line pages). Since the output will be sorted into lexicographic order,
-it may be desired to run the output through
-.Xr sort 1 .
-Sample use:
-.Bd -literal -offset indent
-gctags \-v files \&| sort \-f > index
-vgrind \-x index
-.Ed
+collect symbols other than functions. By default, locate function definitions.
.It Fl w
-suppress warning diagnostics.
-.It Fl x
-.Nm gctags
-produces a list of object
-names, the line number and file name on which each is defined, as well
-as the text of that line and prints this on the standard output. This
-is a simple index which can be printed out as an off-line readable
-function index.
