-.Sh NAME
-.Nm ctags
-.Nd create a tags file
-.Sh SYNOPSIS
-.Nm
-.Op Fl BFadtuwvx
-.Op Fl f Ar tagsfile
-.Ar name ...
-.Sh DESCRIPTION
-.Nm
-makes a tags file for
-.Xr ex 1
-from the specified C,
-Pascal, Fortran,
-.Tn YACC ,
-lex, and lisp 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
-white-space.
-Using the
-.Ar tags
-file,
-.Xr ex 1
-can quickly locate these object definitions.
-Depending upon the options provided to
-.Nm ,
-objects will consist of subroutines, typedefs, defines, structs,
-enums and unions.
-.Bl -tag -width Ds
-.It Fl B
-use backward searching patterns
-.Pq Li ?...? .
-.It Fl F
-use forward searching patterns
-.Pq Li /.../
-(the default).
-.It Fl a
-append to
-.Ar tags
-file.
-.It Fl d
-create tags for
-.Li #defines
-that don't take arguments;
-.Li #defines
-that take arguments are tagged automatically.
-.It Fl f
-Places the tag descriptions in a file called
-.Ar tagsfile .
-The default behaviour is to place them in a file called
-.Ar tags .
-.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
-ctags \-v files \&| sort \-f > index
-vgrind \-x index
-.Ed
-.It Fl w
-suppress warning diagnostics.
-.It Fl x
-.Nm
-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.
-.El
-.Pp
-Files whose names end in
-.Sq \&.c
-or
-.Sq \&.h
-are assumed to be C
-source files and are searched for C style routine and macro definitions.
-Files whose names end in
-.Sq \&.y
-are assumed to be
-.Tn YACC
-source files.
-Files whose names end in
-.Sq \&.l
-are assumed to be lisp files if their
-first non-blank character is
-.Sq \&; ,
-.Sq \&( ,
-or
-.Sq \&[ ,
-otherwise, they are
-treated as lex files.
-Other files are first examined to see if they
-contain any Pascal or Fortran routine definitions, and, if not, are
-searched for C style definitions.
-.Pp
-The tag
-.Li main
-is treated specially in C programs.
-The tag formed
-is created by prepending
-.Ar M
-to the name of the file, with the
-trailing
-.Sq \&.c
-and any leading pathname components removed.
-This
-makes use of
-.Nm
-practical in directories with more than one
-program.
-.Pp
-Yacc and lex files each have a special tag.
-.Ar Yyparse
-is the start
-of the second section of the yacc file, and
-.Ar yylex
-is the start of
-the second section of the lex file.
-.Sh FILES
-.Bl -tag -width tags -compact
-.It Pa tags
-default output tags file
-.El
-.Sh EXIT STATUS
-.Ex -std
-Duplicate objects are not considered errors.
-.Sh SEE ALSO
-.Xr ex 1 ,
-.Xr vi 1
-.Sh HISTORY
-The
-.Nm
-command appeared in
-.Bx 3.0 .
-.Sh BUGS
-Recognition of
-.Em functions  ,
-.Em subroutines
-and
-.Em procedures
-for
-.Tn FORTRAN
-and Pascal is done in a very simpleminded way.
-No attempt
-is made to deal with block structure; if you have two Pascal procedures
-in different blocks with the same name you lose.
-.Nm
-doesn't
-understand about Pascal types.
-.Pp
-The method of deciding whether to look for C, Pascal or
-.Tn FORTRAN
-functions is a hack.
-.Pp
-.Nm
-relies on the input being well formed, and any syntactical
-errors will completely confuse it.
-It also finds some legal syntax
-confusing; for example, since it doesn't understand
-.Li #ifdef Ns 's
-(incidentally, that's a feature, not a bug), any code with unbalanced
-braces inside
-.Li #ifdef Ns 's
-will cause it to become somewhat disoriented.
-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
-.Li typedef Ns 's
-will similarly be noted.
