==============

NAME
----
perf-config - Get and set variables in a configuration file.

SYNOPSIS
--------
[verse]
'perf config' -l | --list

DESCRIPTION
-----------
You can manage variables in a configuration file with this command.

OPTIONS
-------

-l::
--list::
	Show current config variables, name and value, for all sections.

CONFIGURATION FILE
------------------

The perf configuration file contains many variables to change various
aspects of each of its tools, including output, disk usage, etc.
The '$HOME/.perfconfig' file is used to store a per-user configuration.
The file '$(sysconfdir)/perfconfig' can be used to
store a system-wide default configuration.

Syntax
~~~~~~

The file consist of sections. A section starts with its name
surrounded by square brackets and continues till the next section
begins. Each variable must be in a section, and have the form
'name = value', for example:

	[section]
		name1 = value1
		name2 = value2

Section names are case sensitive and can contain any characters except
newline (double quote `"` and backslash have to be escaped as `\"` and `\\`,
respectively). Section headers can't span multiple lines.

Example
~~~~~~~

Given a $HOME/.perfconfig like this:

#
# This is the config file, and
# a '#' and ';' character indicates a comment
#

	[colors]
		# Color variables
		top = red, default
		medium = green, default
		normal = lightgray, default
		selected = white, lightgray
		jump_arrows = blue, default
		addr = magenta, default
		root = white, blue

	[tui]
		# Defaults if linked with libslang
		report = on
		annotate = on
		top = on

	[buildid]
		# Default, disable using /dev/null
		dir = ~/.debug

	[annotate]
		# Defaults
		hide_src_code = false
		use_offset = true
		jump_arrows = true
		show_nr_jumps = false

	[help]
		# Format can be man, info, web or html
		format = man
		autocorrect = 0

	[ui]
		show-headers = true

	[call-graph]
		# fp (framepointer), dwarf
		record-mode = fp
		print-type = graph
		order = caller
		sort-key = function

Variables
~~~~~~~~~

colors.*::
	The variables for customizing the colors used in the output for the
	'report', 'top' and 'annotate' in the TUI. They should specify the
	foreground and background colors, separated by a comma, for example:

		medium = green, lightgray

	If you want to use the color configured for you terminal, just leave it
	as 'default', for example:

		medium = default, lightgray

	Available colors:
	red, yellow, green, cyan, gray, black, blue,
	white, default, magenta, lightgray

	colors.top::
		'top' means a overhead percentage which is more than 5%.
		And values of this variable specify percentage colors.
		Basic key values are foreground-color 'red' and
		background-color 'default'.
	colors.medium::
		'medium' means a overhead percentage which has more than 0.5%.
		Default values are 'green' and 'default'.
	colors.normal::
		'normal' means the rest of overhead percentages
		except 'top', 'medium', 'selected'.
		Default values are 'lightgray' and 'default'.
	colors.selected::
		This selects the colors for the current entry in a list of entries
		from sub-commands (top, report, annotate).
		Default values are 'black' and 'lightgray'.
	colors.jump_arrows::
		Colors for jump arrows on assembly code listings
		such as 'jns', 'jmp', 'jane', etc.
		Default values are 'blue', 'default'.
	colors.addr::
		This selects colors for addresses from 'annotate'.
		Default values are 'magenta', 'default'.
	colors.root::
		Colors for headers in the output of a sub-commands (top, report).
		Default values are 'white', 'blue'.

tui.*, gtk.*::
	Subcommands that can be configured here are 'top', 'report' and 'annotate'.
	These values are booleans, for example:

	[tui]
		top = true

	will make the TUI be the default for the 'top' subcommand. Those will be
	available if the required libs were detected at tool build time.
