PINFO(1)

NAME
pinfo - is user-friendly, console-based viewer for Info documents

SYNTAX
pinfo [options] [infopage]

DESCRIPTION
This is a program for viewing info files. You specify which page you want to read by passing it an infopage argument. This argument contains the name of an info page (i.e. 'bash'). The program will then (by default) search for it in the current directory, /usr/share/info, /usr/info, /usr/local/share/info, /usr/local/info. and /opt/info. The search path can be adjusted by INFOPATH environment variable or in the configuration file. Pinfo will also automatically add the suffix '-info', '-info.Z', '-info.gz', or '-info.bz2'.

When the search for info pages fails, man is called with the infopage argument, and its output is parsed by pinfo. This means that when you don't have the appropriate info page, but have a man page instead; the man page will be viewed.

When no infopage is specified, the default `dir' page is shown.

Supported options are

-h, --help - print help information and exit.

-v, --version - print version information and exit.

-m, --manual - uses manual page instead of info by default. (pinfo -m could be used as a manual pager). Warning: Everything what follows this option is passed to the `man' program. Don't be confused if pinfo options, which followed `-m' don't work. When using this option, pinfo does not parse the info options as usual! It invokes the man part of program.

You can also call the man function of pinfo in another way. When pinfo is called with an argv[0] (the program file name), which contains the word 'man' in its name, the man functions are enabled automatically.

Previously there was a symlink to pinfo, called pman, but I had to remove it from the distribution, since its name was in conflict with some other utility. Anyway, you can feel free to create such a link if you wish.

-r, --raw-filename - uses a raw filename first (i.e. the name which you specified as infopage is considered to be a real file in the specified location).

-f, --file synonym for -r.

-a, --apropos - if this is set, apropos is called when no man or info page could be found.

-c, --cut-man-headers - if this is set, man parsing code will try to cut out the repeated man headers. Use with care. ;)

-s, --squeeze-lines- cut empty lines from manual pages. This option enables auto cutting of every repeated newline in a manual page.

-t, --force-manual-tag-table- forces manual detection of tag table. This allows you to view info pages, which may be corrupted. (as i.e. version of jed's pages, shipped with RH5.0). The tag table corruption usually appears in that the info links, which you follow, move you to quite unexpected nodes.

--node=nodename, --node nodename- Go to the node `nodename' of info file. Since 0.6.7 it is also possible to specify nodes as in standalone info via file names, like `(gcc)Introduction'.

--rcfile=filename, --rcfile filename- Use alternate configuration file.

--long-manual-links, -l- Use long link names in manuals. On some systems the manual hierarchy is divided into subsections like `3ncurses', etc, while on other systems all belongs to section `3'. If this option is what your system is like, feel free to use it.

--clear-at-exit, -x- Clear screen at exit.

The options are handled by GNU getopt, so you can here (as in other programs) abbreviate the option names to the minimal number of characters by which the options differ.

Warning! If you do not have getopt, these options will not work!

DEFAULT KEYS WHEN BROWSING INFO FILE

Just take a look at the example configuration file (below), and at the key descriptions. Keys available in manual viewer differ a bit from the keys available in info viewer.

ENVIRONMENT
There is a variable $INFOPATH, which can specify the paths to be searched for info files. It's format is similar to that of the $PATH variable. An example setting could look like:

/usr/info:/usr/somewhere/info:/not/even/in/usr/info

etc. Directories are separated by colons.

COLOR AND KEY DEFINITIONS

There are configuration files called ~/.pinforc and [prefix]/etc/pinforc, for local and global configuration (where prefix is the prefix of the directory, where pinfo is installed, i.e. /usr/local, or /). Here's an example of such a file; we'll discuss the contents below:

# Here are some color setting.
# Whitespace between the entries is optional.

As you can see, the format is simple. First I'll explain the color definitions. First you must enter a color name (all available color names are present in the example, and they're self explanatory, I think. There is also a special color COLOR_DEFAULT, which stands for transparency). Then you enter the foreground color, and the background color. The BOLD attribute means that we want the foreground color to be highlighted. (i.e. light blue, light green). BLINK attribute is the blinking attribute, or highlighted background in some other configurations.

Now let's move to the key definitions. Here we first put a key name (again all keys are present in the example); then we enter its value -- either surrounded by apostrophes, or a keycode number (like in KEY_REFRESH_1), or its mnemonic code name if its a special key (like i.e. in KEY_FOLLOWLINK_1).

If you wish to specify key by code value, use the supplied program 'testkey' to obtain the needed value. It mainly is a feature, when you want to add some CTRL+letter keybindings, and similar.

For each function you can bind two keys, i.e. you could bind both Enter and Cursor Right to the FollowLink-function. As you can see in the example above, the two key names are KEY_FOLLOWLINK_1 and KEY_FOLLOWLINK_2.

Here's an explanation of the key names:

    KEY_TOTALSEARCH_1

The special mnemonics for keys (which are defined at present) are:

    KEY_BREAK

    KEY_DOWN

    KEY_UP

    KEY_LEFT

    KEY_RIGHT

    KEY_DOWN

    KEY_HOME

    KEY_BACKSPACE

    KEY_NPAGE

    KEY_PPAGE

    KEY_END [Note: this works probably ONLY with Linux ncurses]

    KEY_F(x)

    KEY_CTRL('c')
        - this assigns the key value to a ctrl+c combination. c may be any letter you wish.

    KEY_ALT('c')
        - this assigns the key value to a alt+c combination. c may be any letter you wish. If alt key won't work, you may use ESC+key combination.

    'c' - this means a printable character c. The syntax is just like in C/C++ ;).

    [number]
        - you can also specify key as its code number. It is useful e.g. when specifying control keys, and some nonstandard keys. A numerical value of zero turns given key binding off.

See manual page for curs_getch (3x) for description of their meaning.

Warning! Try not to create some serious key binding conflicts!

The options in the last part of the example configuration file should be fairly self-explanatory. The variables that can be set to true or false do the same things as the command line arguments with the same names.

    MANUAL
        If this is set to true the default is to first check for a man page, instead of a texinfo file.

    CUT-MAN-HEADERS
        If set to true, then pinfo tries to cut off the repeated headers throughout man pages.

    CUT-EMPTY-MAN-LINES
        If set to true, then pinfo tries to cut off the repeated newlines (i.e. it will shorten each set of consecutive newlines to one newline).

    RAW-FILENAME
        If set to true, the file argument is taken to be the name of a file in the current working directory, i.e. the directories in INFOPATH will only be searched if a file with this name is not in the working directory.

    APROPOS
        If set to true, apropos is called if no info or man page is found.

    DONT-HANDLE-WITHOUT-TAG-TABLE
        If set to true , pinfo will not attempt to display texinfo pages without tag tables.

    HTTPVIEWER
        Set this to the program you want to use to follow http links in documents.

    FTPVIEWER
        Set this to the program you want to use to follow ftp links in documents.

    MAILEDITOR
        Set this to your favorite email program, and it will be started if you follow an email link in a document.

    PRINTUTILITY
        Utility, which you use for printing. I.e. `lpr'. If you don't use any, you may also try something like `cat >/dev/lp1', or sth. ;)

    MANLINKS
        This specifies the section names, which may be referenced in your man pages (i.e. Xtoolkit man pages match the section 3Xt (see for example XtVaCreateWidget) manpage), Xlib function pages match section 3X11, etc. Such extensions may not be recognized by default, so it is a good idea to add them).

    INFOPATH
        This allows you to override the default search path for info pages. The paths should be separated by colons.

    MAN-OPTIONS
        This specifies the options, which should be passed to the `man' program. (see man(1) for description of what they're like).

    STDERR-REDIRECTION
        Pinfo allows you to redirect the stderr output of called programs. For example if you don't want to see man's error messages about manual page formatting, you can use STDER-REDIRECTION="2> /dev/null". This is the default.

    LONG-MANUAL-LINKS
        This is another true/false option, which decides whether your system supports long manual section names, or not. (i.e. "3ncurses" instead of "3").

    FILTER-0xB7
        This decides, whether you want to convert 0xb7 chars to `o', or not. For example for iso-8859-2 fonts this makes man's list marks a bit nicer ;) (look for example at perl's man page, to see how those marks look like).

    QUIT-CONFIRMATION
        This decides whether you want to use quit confirmation on exit, or not.

    QUIT-CONFIRM-DEFAULT
        This yes/no option determines the default answer to the QUIT-CONFIRMATION dialog. (default answer is when you press a key, that does not match the asked question).

    CLEAR-SCREEN-AT-EXIT
        This true/false option determines if you want to have your screen cleared at exit, or no.

    CALL-READLINE-HISTORY
        This true/false option determines if you want to have a prompt of last history entry whenever calling readline wrapper, eg. in subsequent searches.

    HIGHLIGHTREGEXP
        This is an option, through which you may pass to pinfo regexps, which should be highlighted when working with document. Warning! This may turn very slow if you use it without care!

    SAFE-USER
        This option is used to pass the name of user, to which suid when pinfo is run with root privileges.

    SAFE-GROUP
        This option is used to pass the name of group, to which suid when pinfo is run with root privileges.

INTERNATIONALIZATION SUPPORT
Pinfo implements general features of gnu gettext library (the thing, which you need to see national messages ;). But it is not the end. Pinfo allows you to use national info pages! You only need to put them to your info directory, into a subdirectory, which is called `$LANG'.
