perf-config(1)
==============
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.
