babeltrace2-sink.text.details \- Babeltrace 2\*(Aqs detailed plain text sink component class
.SH "DESCRIPTION"
.sp
A Babeltrace\ \&2 \fBsink.text.details\fR component deterministically prints the messages it consumes, with all the possible details, to the standard output\&.
.sp
.if n \{\
.RS 4
.\}
.nf
            +\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-\-+

See \fBbabeltrace2-intro\fR(7) to learn more about the Babeltrace\ \&2 project and its core concepts\&.
.sp
The purpose of a \fBsink.text.details\fR component is to always print the same text for the same sequence of consumed messages, whatever the build configuration of the Babeltrace\ \&2 project\&. This can be helpful for testing, debugging, and support\&.
.sp
The output format is optimized for human reading, with colors when the terminal supports it\&. You can control how the component prints color codes with the \fBcolor\fR parameter\&.
.sp
To achieve a reproducible output, a \fBsink.text.details\fR component sorts the members of all unordered sets before it prints them\&. For example, the component sorts enumeration field class mappings by label and, for each mapping, sorts the contained ranges\&.
.sp
In normal mode, each message has at least three lines, the three first being:
.sp
.RS 4
.ie n \{\
\h'-04' 1.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  1." 4.2
.\}
Timing information (cycles and nanoseconds since origin)\&.
.sp
Example:
.sp
.if n \{\
.RS 4
.\}
.nf
[102,423,274,041,829 cycles, 1,441,852,841,550,867,846 ns from origin]

.sp
.RS 4
.ie n \{\
\h'-04' 2.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  2." 4.2
.\}
Unique stream identifier\&.
.sp
To be able to follow a specific trace object (the name and UUID properties of a trace object are optional), the component assigns a unique numeric ID to the trace object when it first encounters it in a stream beginning message\&.
.sp
Example:
.sp
.if n \{\
.RS 4
.\}
.nf
{Trace 1, Stream class ID 0, Stream ID 2}
.fi
.if n \{\
.RE
.\}

.sp
.RS 4
.ie n \{\
\h'-04' 3.\h'+01'\c
.\}
.el \{\
.sp -1
.IP "  3." 4.2
.\}
Message type and basic information\&.
.sp
Examples:
.sp
.if n \{\
.RS 4
.\}
.nf
Packet beginning:
.fi
.if n \{\
.RE

.sp
.if n \{\

.sp
What follows depend on the specific message type\&. The component prints all the available properties and fields in a human\-readable, structured format\&.
.sp
When a \fBsink.text.details\fR component consumes a stream beginning or an event message, it can print a metadata block for all the metadata objects which it did not print yet\&. You can use the \fBwith-metadata\fR parameter to disable this\&.
.sp
You can hide specific properties with the \fBwith-stream-class-name\fR, \fBwith-stream-name\fR, \fBwith-time\fR, \fBwith-trace-name\fR, and \fBwith-uuid\fR parameters\&.
.sp
To make the component hide many message details and print a single message per line, you can enable the compact mode with the \fBcompact\fR parameter\&.
.SH "INITIALIZATION PARAMETERS"
.PP
\fBcolor\fR=(\fBnever\fR | \fBauto\fR | \fBalways\fR) [optional string]
.RS 4
Force the terminal color support, one of:
.PP
\fBauto\fR (default)
.RS 4
Only emit terminal color codes when the standard output and error streams are connected to a color\-capable terminal\&.
.RE
.PP
\fBnever\fR
.RS 4
Never emit terminal color codes\&.
.RE
.PP
\fBalways\fR
.RS 4
Always emit terminal color codes\&.
.RE
.sp
The
\fBBABELTRACE_TERM_COLOR\fR
environment variable overrides this parameter\&.
.RE
.PP
\fBcompact\fR=\fByes\fR [optional boolean]
.RS 4
Enable compact mode\&.
.sp
In compact mode, the component prints one line per message, omitting many details about messages\&. This is useful if you only need the time, type, and very basic information of messages\&.
.sp
In compact mode, the component still prints the full metadata blocks\&. You can remove such blocks with the
\fBwith-metadata\fR
parameter\&.
.RE
.PP
\fBwith-metadata\fR=\fBno\fR [optional boolean]
.RS 4
Do not print metadata blocks\&.
.RE
.PP
\fBwith-stream-class-name\fR=\fBno\fR [optional boolean]
.RS 4
Do not print stream class names\&.
.RE
.PP
\fBwith-stream-name\fR=\fBno\fR [optional boolean]
.RS 4
Do not print stream names\&.
.RE
.PP
\fBwith-time\fR=\fBno\fR [optional boolean]
.RS 4
Do not print timing information\&.
.RE
.PP
\fBwith-trace-name\fR=\fBno\fR [optional boolean]
.RS 4
Do not print trace names\&.
.RE
.PP
\fBwith-uuid\fR=\fBno\fR [optional boolean]
.RS 4
Do not print UUIDs\&.

Single input port\&.
.RE
.SH "ENVIRONMENT VARIABLES"
.PP
\fBBABELTRACE_EXEC_ON_ABORT\fR=\fICMDLINE\fR
.RS 4
Execute the command line
\fICMDLINE\fR, as parsed like a UNIX\ \&98 shell, when any part of the Babeltrace\ \&2 project unexpectedly aborts\&.
.sp
The application only aborts when the executed command returns, ignoring its exit status\&.
.sp
This environment variable is ignored when the application has the
\fBsetuid\fR
or the
\fBsetgid\fR
access right flag set\&.
.RE
.PP
\fBBABELTRACE_TERM_COLOR\fR=(\fBAUTO\fR | \fBNEVER\fR | \fBALWAYS\fR)
.RS 4
Force the terminal color support for the
\fBbabeltrace2\fR(1)
program and the project\(cqs plugins\&.
.sp
The available values are:
.PP
\fBAUTO\fR
.RS 4
Only emit terminal color codes when the standard output and error streams are connected to a color\-capable terminal\&.
.RE
.PP
\fBNEVER\fR
.RS 4
Never emit terminal color codes\&.
.RE
.PP
\fBALWAYS\fR
.RS 4
Always emit terminal color codes\&.
.RE
.RE
.PP
\fBBABELTRACE_TERM_COLOR_BRIGHT_MEANS_BOLD\fR=\fB0\fR
.RS 4
Set to
\fB0\fR
to emit
SGR (see <https://en.wikipedia.org/wiki/ANSI_escape_code>)
codes 90 to 97 for bright colors instead of bold (SGR code\ \&1) and standard color codes (SGR codes 30 to 37)\&.
