.Sh DESCRIPTION
.Nm
is a helper program that displays graphical user
interfaces for other programs.
It renders the GUI definition found in a GtkBuilder XML file
(typically created using the
.Xr glade 1
interface designer), and communicates with the main program solely
through plain text messages via pipes or fifos.
It provides access to a subset of features of a subset of widgets of
GTK+ 3.
Simple one-shot dialogs as well as more complex, long-running programs
can be built using
.Nm ;
see
.Sx EXAMPLES .
.Sh OPTIONS
.Bl -tag -width Ds
.It Fl i Ar in-fifo
Creates a named pipe
.Ar in-fifo
if necessary, sets its permissions to
.Li 0600 ,
and uses it for command input.
.Pp
A command is a line of text.
Its format is
.Qq Ar id Ns Cm \&: Ns Ar action Bq Ar data ,
.Ar id
being the name of the receiving widget;
.Ar data
is separated from the rest of the command by a single whitespace
character.
Commands whose first non-whitespace character is
.Cm #
are considered comments and ignored silently, as are empty input lines.
Any occurences of the two-character sequences
.Cm \en
and
.Cm \er
will be converted into newline or carriage return, respectively.
Every other character following a backslash will be left unchanged,
but the backslash will be removed.
Invalid commands are reported on
.Va stderr
and are otherwise ignored.
See
.Sx WIDGETS
for applicable commands.
.Pp
It is an error if
.Ar in-fifo
exists but is not a named pipe.
The named pipe
.Ar in-fifo
is deleted upon successful program termination.
.Pp
Default command input is
.Va stdin .
.It Fl o Ar out-fifo
Creates a named pipe
.Ar out-fifo
if necessary, sets its permissions to
.Li 0600 ,
and uses it for output of feedback messages from the
graphical user interface.
.Pp
A feedback message is a line of text; its format is
.Qq Ar id Ns Cm \&: Ns Ar info Bq Ar data ,
.Ar id
being the name of the sending widget.
See
.Sx WIDGETS
for possible feedback messages.
.Pp
It is an error if
.Ar out-fifo
exists but is not a named pipe.
The named pipe
.Ar out-fifo
is deleted upon successful program termination.
.Pp
Default feedback-message output is
.Va stdout .
.It Fl b
Runs
.Nm
in the background after printing its process ID to
.Va stdout .
.Pp
It is an error if option
.Fl b
is used and not both
.Fl i Ar in-fifo
and
.Fl o Ar out-fifo
are specified.
.It Fl u Ar builder-file
Displays the graphical user interface
.Ar builder-file
which should be created using the
.Xr glade 1
user interface designer and saved in GtkBuilder (.ui) format.
Widget ids should consist of alphanumeric ASCII characters including
hyphens and underscores.
The main window must must be given the id
.Cm main .
.Pp
Default is
.Pa ./pipeglade.ui .
.It Fl e Ar parent-xid
Embeds the main window into the XEmbed socket
.Ar parent-xid
of another process.
.It Fl l Ar log-file
Appends for each command a line of
.Qq Ar time activity
to
.Ar log-file ,
.Ar time
being the number of microseconds elapsed during
.Ar activity .
.Ar time
and
.Ar activity
are separated by a tab character.
Permissions of
.Ar log-file
are set to
.Li 0600 .
A
.Ar log-file
name of
.Ql -
means
.Va stderr .
.It Fl O Ar err-file
Redirects
.Va stderr ,
appending its output to
.Ar err-file .
Permissions of
.Ar err-file
are set to
.Li 0600 .
.It Fl -display Ar X-server
Uses the display on
.Ar X-server
for user interaction.
.It Fl h
Prints a help message and exits.
.It Fl G
Prints the versions of the underlying GTK+ and cairo libraries and
exits.
.It Fl V
Prints the
.Nm
version and exits.
