'\"
'\" The 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
'\"	Start of list of standard options for a Tk widget.  The
'\"	options follow on successive lines, in four 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.

.SH DESCRIPTION
.PP
The \fByaml\fR package provides a simple Tcl-only library for parsing the
YAML \fIhttp://www.yaml.org/\fR data exchange format as specified in
\fIhttp://www.yaml.org/spec/1.1/\fR.
.PP
The \fByaml\fR package returns
data as a Tcl \fBdict\fR.  Either the \fBdict\fR package or Tcl 8.5 is
required for use.
.SH COMMANDS
.TP
\fB::yaml::yaml2dict\fR ?\fIoptions\fR? \fItxt\fR
.TP
\fB::yaml::yaml2huddle\fR ?\fIoptions\fR? \fItxt\fR
Parse yaml formatted text \fItxt\fR into a Tcl dict/huddle and return the value.
.RS
.TP
\fB\fB-file\fR\fR
\fItxt\fR is a filename of YAML-stream.
.TP
\fB\fB-stream\fR\fR
\fItxt\fR is just a YAML-stream.
.TP
\fB\fB-types\fR \fIlist\fR\fR
The \fIlist\fR is a type list for the yaml-scalar types.(e.g. !!str !!timestamp !!integer !!true ...)
.nf
 -types {timestamp integer null true false}
.fi
In this case, if a string matched "timestamp", converted to the TCL internal timestamp.(e.g. "2001-12-15T02:59:43.1Z" => 1008385183)
.TP
\fB\fB-m:true\fR \fIparam\fR\fR
The \fIparam\fR is two elements of list for the value of true, and considered strings.
.nf
 -m:true {1 {true on + yes y}}
.fi
In this case, the string "yes" found in YAML Stream, automatically converted 1.
.TP
\fB\fB-m:false\fR \fIparam\fR\fR
The \fIparam\fR is two elements of list for the value of false, and considered strings.
.nf
 -m:false {0 {false off - no n}}
.fi
.TP
\fB\fB-m:null\fR \fIparam\fR\fR
The \fIparam\fR is two elements of list for the value of null, and considered strings.
.nf
 -m:null {"" {null nil "" ~}}
.fi
.TP
\fB\fB-validate\fR\fR
Experiment,old: Output stream contains YAML's-tag, each node.
.nf
% puts [::yaml::load -validate {[aaa, bbb]}]
=>
!!seq {{!!str aaa} {!!str bbb}}

.fi
.RE
.TP
\fB::yaml::setOption\fR ?\fIoptions\fR?
Change implicit options for the library.
Now, the params are the same as \fB::yaml::yaml2dict\fR.
Arguments of\fB::yaml::yaml2dict\fR is more priority than this setting.
.TP
\fB::yaml::dict2yaml\fR \fIdict\fR ?\fIindent\fR? ?\fIwordwrap\fR?
.TP
\fB::yaml::list2yaml\fR \fIlist\fR ?\fIindent\fR? ?\fIwordwrap\fR?
.TP
\fB::yaml::huddle2yaml\fR \fIhuddle\fR ?\fIindent\fR? ?\fIwordwrap\fR?
Convert a dict/list/huddle object into YAML stream.
.RS
.TP
indent
spaces indent of each block node.
currently default is 2.
.TP
wordwrap
word wrap for YAML stream.
currently default is 40.
