UPDATE-OTAGS(8) 					  System administration commands					   UPDATE-OTAGS(8)

NAME

       update-otags - update system-wide tags tables

SYNOPSIS

       update-otags

DESCRIPTION

       update-otags  runs  otags  on  the  system-wide installed OCaml files (in ocamlc -where). This makes it possible to use the tag-features of
       vi/vim and Emacs to jump to the declarations of library functions in the system-wide installed .mli files to read the documentation that is
       hopefully embedded in those files.

       To  use the system-wide tags table in Emacs, use M-x visit-tags-table <RET> /var/lib/otags/TAGS.  To load it by default, customize tags-ta-
       ble-list to contain /var/lib/otags (by using M-x customize-variable, for instance).

       For vim use :set tags=/var/lib/otags/tags or add set tags=/var/lib/otags/tags to your .vimrc.

       One would typically update the system-wide tags tables with a cron-job once per week or day.

FILES

       /var/lib/otags/{TAGS,tags}
	      System-wide tags table for Emacs and vi/vim.

       /usr/share/otags/hints
	      Directory for parsing hints. Packages that install files in non-standard syntax can install a parser hints file for  otags  in  this
	      directory, see option -parser-hints in the otags(1) manual.

BUGS

       Camlp4 (and therefore otags too) cannot parse all legal OCaml sources. Most notably, camlp4 dies on pervasives.mli (see bug #5495).  There-
       fore, none of the core library functions are tagged.

       Various files in the system-wide OCaml directory are written in the revised syntax or require other syntax extensions. In  principle  these
       files can all be properly tagged, but the dumb update-otags script tries to parse all files with the original syntax.

CREDITS

       update-otags  appeared  first in Debian Etch (see Debian bug #341939). It has been added to the contrib directory with an improved man page
       in otags 3.12.2.
