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

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
		code = 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
