flaw(7) Miscellaneous Information Manual flaw(7)
NAME
flaw - a Lua OO management framework for awesome WM widgets
DESCRIPTION
flaw stands for Fully Loaded AWesome. It is a LUA object oriented li-
brary providing a thin abstraction layer above awesome widgets. It is
aimed at being simple and resources efficient.
To achieve these goals, flaw provides the following concepts.
gadgets
To add functionality to awesome widgets, flaw defines gadget ob-
jects, which are a wrapper around a widget. All gadgets have
properties, events, a refresh mechanism and a data provider (see
below). Gadgets can wrap all awesome widget type, namely text
boxes, image boxes, graphs or progress bars. flaw provides many
gadgets for common system information (like CPU or memory activ-
ity).
provider
flaw tries to minimise system access and data refresh. Since
all information do not have the same expiration rate, all gad-
gets refresh independently. And since some gadgets can share
information, all data is provided by providers which can be
shared among gadgets. Providers maintain status data from the
system and refreshes only when necessary (ie. when the gadget
with the shortest refresh rate demands it).
events Events are a way for the user to modify the gadget behaviour or
properties when some conditions are met. An event is composed
of a trigger, which computes the condition, and an action.
Event triggers are tested by the providers only when data
changes. Both the condition and the action are provided by the
user.
USAGE
flaw depends on the lua-filesystem package which can be found
http://luaforge.net/projects/luafilesystem. Once installed, the fol-
lowing statement must be inserted in awesome configuration before any
flaw gadget or mechanism is used.
require('flaw')
Using flaw consists in creating gadgets, passing them parameters to
customize their display and events to add some behaviour to them, and
then adding them in a wibox like any other awesome widget. flaw and
awful gadgets can live together. The complete flaw documentation is
available in Luadoc format. Enter the following command to generate it.
LUA_PATH="path_toflaw/doclet/html/?;;" luadoc -d html --nofiles
*.lua
DIAGNOSTICS
flaw tries to recover upon bad invocations. When something wrong oc-
curs, it outputs warning or error messages to stderr (for example, if
awesome was started with xsession, output will be found in ~/.xsession-
errors ).
BUGS
Certainly a lot.
