# Tips for upgrading your configuration
|
||
|
||
<a name="v4"></a>
|
||
## From 3.5 to 4.0
|
||
|
||
The
|
||
**best advice is to start from the default `rc.lua` and backport any changes**
|
||
you might have added to your `rc.lua`.
|
||
This avoids most of the possible errors due to missing important changes.
|
||
|
||
To do this, you can download the default rc.lua for 3.5.9
|
||
[here](https://github.com/awesomeWM/awesome/blob/v3.5.9/awesomerc.lua.in), and
|
||
then compare your existing rc.lua with the 3.5.9 default using your diff tool of
|
||
choice. Write down the changes, then apply these to the 4.0 default rc.lua,
|
||
which you can find at /etc/xdg/awesome/rc.lua after the upgrade, or
|
||
[here](../sample%20files/rc.lua.html) if you have not yet performed the upgrade.
|
||
|
||
If you still wish to ignore this advice, first read the
|
||
<a href="89-NEWS.md.html#v4">NEWS</a> section about the breaking changes. This
|
||
document assumes you did.
|
||
|
||
Be warned, even if it looks like it's working after changing some lines, **it wont
|
||
supports dynamic screen changes and will have many subtle bugs**. The changes
|
||
mentioned below **are important for the stability of your window manager**.
|
||
|
||
Here is a diff of the 3.5.9 `rc.lua` with the 4.0 one. All changes due to
|
||
new features and new syntaxes have been removed. A `-` in front of the line
|
||
correspond to content of the 3.5 `rc.lua` and `+` its replacement in 4.0.
|
||
|
||
This document does not cover the new features added in the Awesome v4 `rc.lua`,
|
||
it only covers the minimal required changes to have a properly behaving config.
|
||
|
||
To test during the port, we recommend the `Xephyr` X11 server.
|
||
|
||
If Awesome v4 **is not installed yet**, we recommend to install it in its own
|
||
prefix to avoid conflicts in case you wish to stay on 3.5 for a little
|
||
longer:
|
||
|
||
cd path/to/awesome/code
|
||
mkdir -p $HOME/.config/awesome4
|
||
mkdir build -p
|
||
cd build
|
||
|
||
# Install in a local folder, this assumes all the dependencies are installed
|
||
cmake -DCMAKE_INSTALL_PREFIX=$HOME/awesome4_test ..
|
||
make -j4
|
||
|
||
# Use a copy of rc.lua to avoid it being overwritten accidentally
|
||
cp awesomerc.lua $HOME/.config/awesome4/rc.lua
|
||
|
||
make install
|
||
|
||
# Start Awesome in a 1280x800 window
|
||
Xephyr :1 -screen 1280x800 &
|
||
DISPLAY=:1 $HOME/awesome4_test/bin/awesome \
|
||
-c $HOME/.config/awesome4/rc.lua \
|
||
--search $HOME/awesome4_test/share/awesome/lib
|
||
|
||
If Awesome v4 is **already installed**, then backup your old `rc.lua` and overwrite
|
||
`~/.config/awesome/rc.lua` (replace this by another path if you use a custom
|
||
XDH config local directory). And only execute:
|
||
|
||
Xephyr :1 -screen 1280x800 &
|
||
DISPLAY=:1 awesome
|
||
|
||
Screens are now added and removed without reloading `rc.lua`. The wallpaper are
|
||
now set in a signal callback.
|
||
|
||
--- {{{ Wallpaper
|
||
-if `beautiful.wallpaper` then
|
||
- for s = 1, screen.count() do
|
||
- `gears.wallpaper.maximized`(beautiful.wallpaper, s, true)
|
||
- end
|
||
-end
|
||
--- }}}
|
||
|
||
+local function set_wallpaper(s)
|
||
+ -- Wallpaper
|
||
+ if `beautiful.wallpaper` then
|
||
+ local wallpaper = `beautiful.wallpaper`
|
||
+ -- If wallpaper is a function, call it with the screen
|
||
+ if type(wallpaper) == "function" then
|
||
+ wallpaper = wallpaper(s)
|
||
+ end
|
||
+ `gears.wallpaper.maximized`(wallpaper, s, true)
|
||
+ end
|
||
+end
|
||
+
|
||
+-- Re-set wallpaper when a screen's geometry changes (e.g. different resolution)
|
||
+`screen.connect_signal`("property::geometry", set_wallpaper)
|
||
|
||
Tags need to be created for each screens, the old static initialization cannot
|
||
work. Remove this section.
|
||
|
||
--- {{{ Tags
|
||
--- Define a tag table which hold all screen tags.
|
||
-tags = {}
|
||
-for s = 1, `screen.count`() do
|
||
- -- Each screen has its own tag table.
|
||
- tags[s] = awful.tag({ 1, 2, 3, 4, 5, 6, 7, 8, 9 }, s, layouts[1])
|
||
- end
|
||
--- }}}
|
||
|
||
The `quit` menu command must be wrapped in a function, otherwise an error
|
||
occurs due to mismatched argument types from the v4 `awful.menu` library.
|
||
|
||
-- {{{ Menu
|
||
-- Create a laucher widget and a main menu
|
||
myawesomemenu = {
|
||
{ "manual", terminal .. " -e man awesome" },
|
||
{ "edit config", editor_cmd .. " " .. awesome.conffile },
|
||
{ "restart", awesome.restart },
|
||
- { "quit", awesome.quit }
|
||
+ { "quit", function() awesome.quit() end}
|
||
}
|
||
|
||
The textclock is now part of the `wibox` library, rename it.
|
||
|
||
-- {{{ Wibar
|
||
-- Create a textclock widget
|
||
-mytextclock = `awful.widget.textclock`()
|
||
+mytextclock = `wibox.widget.textclock`()
|
||
|
||
|
||
Widgets were previously added to static global tables. This isn't going to
|
||
behave correctly when screen are added and removed. Remove this section.
|
||
|

|

-mywibox = {}

they are still supported, but will be removed in the next release.

end),

This section is **very important**. This is where adding and removing screens is
|
||
handled (including during startup). Note that the `mysomething` table
|

previously removed are replaced by custom screens attributes.

`awful.util.spawn` is now called `awful.spawn`.

Another dynamic screen related changes.

Another function-to-method API change:

|
||
|
||
The `mod4+[1-9]` keybindings also have some changes related to deprecated
|
||
functions.
|
||
|
||
-- Bind all key numbers to tags.
|
||
-- Be careful: we use keycodes to make it works on any keyboard layout.
|
||
-- This should map on the top row of your keyboard, usually 1 to 9.
|
||
for i = 1, 9 do
|
||
-- View tag only.
|
||
awful.key({ modkey }, "#" .. i + 9,
|
||
function ()
|
||
- local screen = `mouse.screen`
|
||
- local tag = `awful.tag.gettags`(screen)[i]
|
||
+ local screen = `awful.screen.focused`()
|

|
||
+ )
|

|
||
|
||
The default rules need to be changed to avoid having offscreen clients:
|
||
|
||
awful.rules.rules = {
|
||
-- All clients will match this rule.
|
||
{ rule = { },
|
||
properties = { border_width = beautiful.border_width,
|
||
awful.rules.rules = {
|
||
focus = awful.client.focus.filter,
|
||
raise = true,
|
||
keys = clientkeys,
|
||
+ buttons = clientbuttons,
|
||
+ screen = `awful.screen.preferred`,
|
||
+ placement = `awful.placement.no_overlap`+`awful.placement.no_offscreen`
|
||
|
||
The `tags` global table has been removed to support dynamic screens, you can
|
||
now access tags by name.
|
||
|
||
- -- properties = { tag = tags[1][2] } },
|
||
+ -- properties = { screen = 1, tag = "2" } },
|
||
|
||
If you need to get the current client object in global context, currently you can use
|
||
`client.focus` for it. E.g., to mark/unmark the client:
|
||
|
||
- awful.client.mark()
|
||
+ client.focus.marked = true
|
||
|
||
- awful.client.unmark()
|
||
+ client.focus.marked = false
|
