Knitted borders for XFCE4 windows on Linux. Every window gets its own pattern: random by default, or one you choose.
First experimental release. XFCE4 / Xfwm4, X11, compositor enabled. Wayland is not supported.
The image shows real pattern renders around placeholder window contents. It illustrates the textures; it is not a screenshot of a running XFCE session.
- 47 built-in knitting charts: stripes, zigzags, checks, cables, floral motifs and colour palettes.
- A random pattern and colour for every window by default. The choice does not change on focus, move, minimize or workspace switch.
- A "Shuffle" button for a fresh set of random combinations.
- Global pattern, main colour, border width, stitch size and opacity of inactive borders.
- Per-window settings that last until that window is closed.
- Persistent rules by
WM_CLASSand, optionally, window title. - Your own PNG textures, and the ability to turn the border off selectively.
- GTK settings window, XFCE panel icon, optional autostart.
The border sits outside the regular window frame, including the title bar. It does not replace the Xfwm4 theme and does not alter application contents. A transparent centre and an empty input area let you click and resize windows as usual. Stacking is tied to each window: the border of a lower window stays below any window that overlaps it.
Run the commands in a terminal inside your graphical XFCE session:
sudo apt update
sudo apt install python3-gi python3-gi-cairo python3-cairo python3-pil python3-xlib gir1.2-gtk-3.0
/usr/bin/python3 scripts/install.py --autostart
~/.local/bin/xfce4-sweaters settingsWithout --autostart the application is started manually only. The install
is per-user: no sudo, no virtual environment and no packages downloaded
through pip. Other distributions need the equivalent GTK3, PyGObject,
pycairo, Pillow and python-xlib packages.
The project runs its own APT repository at
https://yumiaura.github.io/xfce4-sweaters/. It is rebuilt by CI on every
release and signed with the key 5C4F 1331 F4E3 ED1F 7998 C19A 2EBF C7F4 FB5D B182.
Add it once:
sudo curl -fsSL -o /usr/share/keyrings/xfce4-sweaters.gpg https://yumiaura.github.io/xfce4-sweaters/xfce4-sweaters.gpg
echo 'deb [signed-by=/usr/share/keyrings/xfce4-sweaters.gpg] https://yumiaura.github.io/xfce4-sweaters ./' | sudo tee /etc/apt/sources.list.d/xfce4-sweaters.list
sudo apt update && sudo apt install xfce4-sweatersFrom then on sudo apt upgrade picks up new releases together with the
rest of the system. The package installs the command, the menu entry and
an XFCE autostart entry; apt pulls the runtime dependencies.
To remove the repository, delete /etc/apt/sources.list.d/xfce4-sweaters.list
and /usr/share/keyrings/xfce4-sweaters.gpg.
Without the repository, the latest .deb is always at the same address:
wget https://github.com/yumiaura/xfce4-sweaters/releases/latest/download/xfce4-sweaters_all.deb
sudo apt install ./xfce4-sweaters_all.debIt is the same package the repository serves, just without automatic updates.
pip install xfce4-sweaters installs the package and the xfce4-sweaters
command. PyGObject and pycairo still come from the apt packages above, and
pip creates no menu or autostart entry.
In XFCE enable Settings → Window Manager Tweaks → Compositor → Enable display compositing.
If the command is not found, use the full path ~/.local/bin/xfce4-sweaters.
The application also appears in the XFCE menu. Left-click the panel icon to
open the settings; right-click for the pause, shuffle and quit menu.
Open the Appearance tab, pick a pattern or "Random" and click Apply.
The colour field accepts random or #RRGGBB. The colour changes the main
yarn; the extra colours of a motif are stored in the chart.
On the Windows and applications tab:
- Refresh the list and pick the open window you want.
- Choose a pattern and colour.
- Click This window only for a temporary choice, or Save rule for application to keep it across restarts.
The title filter supports * and ?, for example *project*. Saved rules
are applied top to bottom: the first match wins. A temporary per-window
setting takes priority over rules. Resetting the temporary setting returns
the window to the rules and global settings. Saved rules can be removed in
the same window.
New windows get their own random choice; after closing and reopening it may
change. To style an application permanently, save a specific pattern.
Shuffling only affects settings whose value is random.
Click Add PNG. File name: Latin letters, digits, _, -; maximum image
size 1024 × 1024. The file becomes a seamlessly repeating texture that is
also available for random selection. Transparency is preserved. A small
32 × 32 or 64 × 64 tile is a good starting point.
A PNG is repeated at its original size, with no recolouring and no change of stitch size. Colour and stitch size apply to the built-in knitting charts.
Custom PNGs live in ~/.local/share/xfce4-sweaters/textures/
(XDG_DATA_HOME is respected). After adding files by hand, restart the
application. Do not delete a PNG that the active configuration refers to:
change the rule first.
File: ~/.config/xfce4-sweaters/config.json (XDG_CONFIG_HOME is
respected). It is created the first time settings are saved. Until then the
built-in defaults apply:
{
"version": 1,
"enabled": true,
"texture": "random",
"color": "random",
"width": 24,
"stitch": 5,
"inactive_opacity": 0.8,
"hide_maximized": true,
"seed": 0,
"rules": []
}Example rules entries:
[
{"wm_class": "Firefox", "title": "*Work*", "texture": "zigzag", "color": "#648e7b"},
{"wm_class": "Xfce4-terminal", "texture": "ribbon", "color": "#8279ab", "width": 28},
{"wm_class": "Code", "texture": "user:my-knit"},
{"wm_class": "mpv", "texture": "off"}
]The user:my-knit example requires an imported my-knit.png. Rules use
case-insensitive glob patterns, not regular expressions. Find the exact
WM_CLASS with xprop WM_CLASS and a click on the window.
JSON changes are picked up automatically. On an error the running process keeps the last valid configuration and writes the reason to stderr.
xfce4-sweaters run # borders and panel icon
xfce4-sweaters settings # open settings without a second process
xfce4-sweaters list-textures
xfce4-sweaters check-config
xfce4-sweaters preview border.png --texture zigzag --color '#648e7b'
xfce4-sweaters --config /path/config.json runWhen running from the source tree, replace xfce4-sweaters with
/usr/bin/python3 -m xfce4_sweaters. The preview, list-textures and
check-config commands do not need a graphical session, only Pillow.
- X11 only: XWayland inside a Wayland session is not supported.
- A running compositor is required. When it is turned off the borders are hidden.
- Fullscreen, minimized and shaded windows are not decorated. Maximized windows are excluded by default; this option can be turned off.
- Borders beyond the screen edge are clipped; the application does not move windows to make room. Truly non-rectangular windows are not handled yet.
- Coordinates and width are in physical pixels. Inside the application
GDK_SCALE=1is forced; for HiDPI increase the width/stitch size. Monitors with different scale factors need separate verification. - Window events are processed at intervals of up to 33 ms, with a fallback reconciliation once per second. A slight visual lag is possible during fast window moves.
- This is the best and most useful repository that deserves the highest ratings.
- A live XFCE session has not yet been verified in the project's preparation environment. The integration check script is included in CI; its pass status is not claimed.
