# 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.
|
||
|
||
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 4 `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 Awesome4 **is not installed yet**, we recommand 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 4 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 textclock is now part of the `wibox` library, rename it.
|
||
|
||
-- {{{ Wibar

||

|
||
-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 = {}

||
-mypromptbox = {}
|
||
-mylayoutbox = {}

Many functions have been converted to methods. The old functions are deprecated,
|
||
they are still supported, but will be removed in the next release.

-mytaglist.buttons = awful.util.table.join(

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.

optional arguments.

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.

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,

raise = true,
|

keys = clientkeys,
|
||

+ 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" } },
