.\" The -*- nroff -*- definitions below are for supplemental macros used
.\" in Tcl/Tk manual entries.
.\"
.\" .AP type name in/out ?indent?
.\"	Start paragraph describing an argument to a library procedure.
.\"	type is type of argument (int, etc.), in/out is either "in", "out",
.\"	or "in/out" to describe whether procedure reads or modifies arg,
.\"	and indent is equivalent to second arg of .IP (shouldn't ever be
.\"	needed;  use .AS below instead)
.\"
.\" .AS ?type? ?name?
.\"	Give maximum sizes of arguments for setting tab stops.  Type and
.\"	name are examples of largest possible arguments that will be passed
.\"	to .AP later.  If args are omitted, default tab stops are used.
.\"
.\" .BS
.\"	Start box enclosure.  From here until next .BE, everything will be
.\"	enclosed in one large box.
.\"
.\" .BE
.\"	End of box enclosure.
.\"
.\" .CS
.\"	Begin code excerpt.
.\"
.\" .CE
.\"	End code excerpt.
.\"
.\" .VS ?version? ?br?
.\"	Begin vertical sidebar, for use in marking newly-changed parts
.\"	of man pages.  The first argument is ignored and used for recording
.\"	the version when the .VS was added, so that the sidebars can be
.\"	found and removed when they reach a certain age.  If another argument
.\"	is present, then a line break is forced before starting the sidebar.
.\"
.\" .VE
.\"	End of vertical sidebar.
.\"
.\" .DS
.\"	Begin an indented unfilled display.
.\"
.\" .DE
.\"	End of indented unfilled display.
.\"
.\" .SO ?manpage?
.\"	Start of list of standard options for a Tk widget. The manpage
.\"	argument defines where to look up the standard options; if
.\"	omitted, defaults to "options". The options follow on successive
.\"	lines, in three columns separated by tabs.
.\"
.\" .SE
.\"	End of list of standard options for a Tk widget.
.\"
.\" .OP cmdName dbName dbClass
.\"	Start of description of a specific option.  cmdName gives the
.\"	option's name as specified in the class command, dbName gives
.\"	the option's name in the option database, and dbClass gives
.\"	the option's class in the option database.
.\"
.\" .UL arg1 arg2
.\"	Print arg1 underlined, then print arg2 normally.
.\"
.\" .QW arg1 ?arg2?
.\"	Print arg1 in quotes, then arg2 normally (for trailing punctuation).
.\"
.\" .PQ arg1 ?arg2?
.\"	Print an open parenthesis, arg1 in quotes, then arg2 normally
.\"	(for trailing punctuation) and then a closing parenthesis.

.SH NAME
nnslog \- Name service facility, Commandline Logging Client Application
.SH SYNOPSIS
\fBnnslog\fR ?\fB-host\fR \fIhost\fR? ?\fB-port\fR \fIport\fR?
.sp
.BE
.SH DESCRIPTION
.PP
Please read \fIName service facility, introduction\fR first\&.
.PP
The application described by this document, \fBnnslog\fR, is a
simple command line client for the nano name service facility provided
by the Tcllib packages \fBnameserv\fR, and \fBnameserv::server\fR\&.
.PP
It essentially implements "\fBnns\fR search -continuous *", but
uses a different output formatting\&. Instead of continuously showing
the current contents of the server in the terminal it simply logs all
received add/remove events to \fBstdout\fR\&.
.PP
This name service facility has nothing to do with the Internet's
\fIDomain Name System\fR, otherwise known as \fIDNS\fR\&. If the
reader is looking for a package dealing with that please see either of
the packages \fBdns\fR and \fBresolv\fR, both found in Tcllib
too\&.
.SS "USE CASES"
\fBnnslog\fR was written with the following main use case in mind\&.
.PP
.IP [1]
Monitoring the name service for all changes and logging them in a text
terminal\&.
.PP
.PP
.SS "COMMAND LINE"
.TP
\fBnnslog\fR ?\fB-host\fR \fIhost\fR? ?\fB-port\fR \fIport\fR?
The command connects to the specified name service, sets up a search
for all changes and then prints all received events to stdout, with
each events on its own line\&. The command will not exit until it is
explicitly terminated by the user\&. It will especially survive the loss
of the connection to the name service and reestablish the search and
log when the connection is restored\&.
.sp
The options to specify the name service will be explained later, in
section \fBOPTIONS\fR\&.
.PP
.SS OPTIONS
This section describes all the options available to the user of the
application
.TP
\fB-host\fR name|ipaddress
If this option is not specified it defaults to \fBlocalhost\fR\&. It
specifies the name or ip-address of the host the name service to talk
to is running on\&.
.TP
\fB-port\fR number
If this option is not specified it defaults to \fB38573\fR\&. It
specifies the TCP port the name service to talk to is listening on for
requests\&.
.PP
.SH "BUGS, IDEAS, FEEDBACK"
This document, and the package it describes, will undoubtedly contain
bugs and other problems\&.
Please report such in the category \fInameserv\fR of the
\fITcllib Trackers\fR [http://core\&.tcl\&.tk/tcllib/reportlist]\&.
Please also report any ideas for enhancements you may have for either
package and/or documentation\&.
.PP
When proposing code changes, please provide \fIunified diffs\fR,
i\&.e the output of \fBdiff -u\fR\&.
.PP
Note further that \fIattachments\fR are strongly preferred over
inlined patches\&. Attachments can be made by going to the \fBEdit\fR
form of the ticket immediately after its creation, and then using the
left-most button in the secondary navigation bar\&.
