NAMEpinfo - curses based lynx-style info browser
SYNTAXpinfo [options] [infopage]
DESCRIPTIONThis 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. At present other suffixes are not recognized, but you can easily add them to the function openinfo() in filehandling_functions.c.
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 dont 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. Dont be confused if pinfo options, which followed -m dont 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 (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 jeds 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.
ENVIRONMENTThere is a variable $INFOPATH, which can specify the paths to be searched for info files. Its format is similar to that of the $PATH variable. An example setting could look like:
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 /). Heres an example of such a file; well discuss the contents below:
As you can see, the format is simple. First Ill explain the color definitions. First you must enter a color name (all available color names are present in the example, and theyre 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 lets 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.
Heres an explanation of the key names:
|Key for searching through all nodes of info file.|
|Alternate key for searching through all nodes of info file.|
|Key for searching through current node (or manual).|

|KEY_DOWN_2||Alternate key for scrolling the text down one line.|
|KEY_TOP_1||Key for going to the top (first) node.|
|KEY_TOP_2||Alternate key for going to the top (first) node.|
|KEY_BACK_1||Key for going back (in the history of viewed nodes).|
|KEY_BACK_2||Alternate key for going back (in the history of viewed nodes).|
|Key for following a hypertext link.|
|Alternate key for following a hypertext link.|

|Key for going to a specified line in file.|
|Alternate key for going to a specified line in file.|
|Key for printing viewed node or man page.|
Alternate key for printing viewed node or man page.
The special mnemonics for keys (which are defined at present) are:
KEY_END [Note: this works probably ONLY with Linux ncurses]
|- 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 wont work, you may use ESC+key combination.|
|c||- this means a printable character c. The syntax is just like in C/C++ ;).|
- 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.
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.|
|If set to true, then pinfo tries to cut off the repeated headers throughout man pages.|
|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).|
|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.|
|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.|
|Utility, which you use for printing. I.e. lpr. If you dont 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.|
|This specifies the options, which should be passed to the man program. (see man(1) for description of what theyre like).|
|Pinfo allows you to redirect the stderr output of called programs. For example if you dont want to see mans error messages about manual page formatting, you can use STDER-REDIRECTION="2> /dev/null". This is the default.|
|This is another true/false option, which decides whether your system supports long manual section names, or not. (i.e. "3ncurses" instead of "3").|
|This decides, whether you want to convert 0xb7 chars to o, or not. For example for iso-8859-2 fonts this makes mans list marks a bit nicer ;) (look for example at perls man page, to see how those marks look like).|
|This decides whether you want to use quit confirmation on exit, or not.|
|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).|
|This true/false option determines if you want to have your screen cleared at exit, or no.|
|This true/false option determines if you want to have a prompt of last history entry whenever calling readline wrapper, eg. in subsequent searches.|
|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.|
This option is used to pass the name of group, to which suid when pinfo is
run with root privileges.
INTERNATIONALIZATION SUPPORTPinfo 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.
