File: texinfo.info, Node: Other Info Directories, Next: Installing Dir Entries, Prev: New Info File, Up: Install an Info File Info Files in Other Directories =============================== If an Info file is not in the `info' directory, there are three ways to specify its location: * Write the pathname in the `dir' file as the second part of the menu. * If you are using Emacs, list the name of the file in a second `dir' file, in its directory; and then add the name of that directory to the `Info-directory-list' variable in your personal or site initialization file. This tells Emacs where to look for `dir' files. Emacs merges the files named `dir' from each of the listed directories. (In Emacs version 18, you can set the `Info-directory' variable to the name of only one directory.) * Specify the Info directory name in the `INFOPATH' environment variable in your `.profile' or `.cshrc' initialization file. (Only you and others who set this environment variable will be able to find Info files whose location is specified this way.) For example, to reach a test file in the `/home/bob/manuals' directory, you could add an entry like this to the menu in the `dir' file: * Test: (/home/bob/manuals/info-test). Bob's own test file. In this case, the absolute file name of the `info-test' file is written as the second part of the menu entry. Alternatively, you could write the following in your `.emacs' file: (setq Info-directory-list '("/home/bob/manuals" "/usr/local/info")) This tells Emacs to merge the `dir' file from the `/home/bob/manuals' directory with the `dir' file from the `/usr/local/info' directory. Info will list the `/home/bob/manuals/info-test' file as a menu entry in the `/home/bob/manuals/dir' file. Finally, you can tell Info where to look by setting the `INFOPATH' environment variable in your `.cshrc' or `.profile' file. If you use a Bourne-compatible shell such as `sh' or `bash' for your shell command interpreter, you set the `INFOPATH' environment variable in the `.profile' initialization file; but if you use `csh' or `tcsh', you must set the variable in the `.cshrc' initialization file. The two types of shells use different syntax. * In a `.cshrc' file, you could set the `INFOPATH' variable as follows: setenv INFOPATH .:~/manuals:/usr/local/emacs/info * In a `.profile' file, you would achieve the same effect by writing: INFOPATH=.:$HOME/manuals:/usr/local/emacs/info export INFOPATH The `.' indicates the current directory as usual. Emacs uses the `INFOPATH' environment variable to initialize the value of Emacs's own `Info-directory-list' variable. However you set `INFOPATH', if its last character is a colon, this is replaced by the default (compiled-in) path. This gives you a way to augment the default path with new directories without having to list all the standard places. For example (using `sh' syntax: INFOPATH=/local/info: export INFOPATH will search `/local/info' first, then the standard directories. Leading or doubled colons are not treated specially.  File: texinfo.info, Node: Installing Dir Entries, Next: Invoking install-info, Prev: Other Info Directories, Up: Install an Info File Installing Info Directory Files =============================== When you install an Info file onto your system, you can use the program `install-info' to update the Info directory file `dir'. Normally the makefile for the package runs `install-info', just after copying the Info file into its proper installed location. In order for the Info file to work with `install-info', you should use the commands `@dircategory' and `@direntry' in the Texinfo source file. Use `@direntry' to specify the menu entry to add to the Info directory file, and use `@dircategory' to specify which part of the Info directory to put it in. Here is how these commands are used in this manual: @dircategory Texinfo documentation system @direntry * Texinfo: (texinfo). The GNU documentation format. * install-info: (texinfo)Invoking install-info. ... ... @end direntry Here's what this produces in the Info file: INFO-DIR-SECTION Texinfo documentation system START-INFO-DIR-ENTRY * Texinfo: (texinfo). The GNU documentation format. * install-info: (texinfo)Invoking install-info. ... ... END-INFO-DIR-ENTRY The `install-info' program sees these lines in the Info file, and that is how it knows what to do. Always use the `@direntry' and `@dircategory' commands near the beginning of the Texinfo input, before the first `@node' command. If you use them later on in the input, `install-info' will not notice them. If you use `@dircategory' more than once in the Texinfo source, each usage specifies one category; the new menu entry is added to the Info directory file in each of the categories you specify. If you use `@direntry' more than once, each usage specifies one menu entry; each of these menu entries is added to the directory in each of the specified categories.  File: texinfo.info, Node: Invoking install-info, Prev: Installing Dir Entries, Up: Install an Info File Invoking install-info ===================== `install-info' inserts menu entries from an Info file into the top-level `dir' file in the Info system (see the previous sections for an explanation of how the `dir' file works). It's most often run as part of software installation, or when constructing a dir file for all manuals on a system. Synopsis: install-info [OPTION]... [INFO-FILE [DIR-FILE]] If INFO-FILE or DIR-FILE are not specified, the various options (described below) that define them must be. There are no compile-time defaults, and standard input is never used. `install-info' can read only one info file and write only one dir file per invocation. If DIR-FILE (however specified) does not exist, `install-info' creates it if possible (with no entries). Options: `--delete' Delete the entries in INFO-FILE from DIR-FILE. The file name in the entry in DIR-FILE must be INFO-FILE (except for an optional `.info' in either one). Don't insert any new entries. `--dir-file=NAME' Specify file name of the Info directory file. This is equivalent to using the DIR-FILE argument. `--entry=TEXT' Insert TEXT as an Info directory entry; TEXT should have the form of an Info menu item line plus zero or more extra lines starting with whitespace. If you specify more than one entry, they are all added. If you don't specify any entries, they are determined from information in the Info file itself. `--help' Display a usage message listing basic usage and all available options, then exit successfully. `--info-file=FILE' Specify Info file to install in the directory. This is equivalent to using the INFO-FILE argument. `--info-dir=DIR' Equivalent to `--dir-file=DIR/dir'. `--item=TEXT' Same as `--entry=TEXT'. An Info directory entry is actually a menu item. `--quiet' Suppress warnings. `--remove' Same as `--delete'. `--section=SEC' Put this file's entries in section SEC of the directory. If you specify more than one section, all the entries are added in each of the sections. If you don't specify any sections, they are determined from information in the Info file itself. `--version' Display version information and exit successfully.
