CWM Patches

A collection of patches for the CWM window manager from OpenBSD. These patches are also applicable to Christian Neukirchen's portable CWM. A development branch that includes all these patches is available on Github.

Bugfixes

Fix moving of clients to group 0

cwm-movetogroup0.patch

Some clients (e.g., stalonetray) are shy and may hide at start-up if configured with autogroup 0. This patch fixes this issue. (Fixed in OpenBSD 6.1)

Fix screen_area(), remove unused fields from region_ctx

cwm-screen-area.patch

In screen_area(), if no matching region is found, the gap will effectively be applied one time too many. Additionally, region_ctx.work is never used, and .area is the same as .view, so I removed these (except .view).

If cwm-keep-visible.patch is applied, this patch cannot be applied and is not needed.

Smaller patches

cwm-ignored-borders.patch: Don't put border on ignored clients when returning from fullscreen. (In OpenBSD 6.1)

cwm-resize-new.patch: Resize new clients after client_placecalc(). This is needed if client_placecalc() decides to change size of the new window. (In OpenBSD 6.1)

cwm-ptrwarp-inbound.patch: Ensure pointer is within warped-to window. This is relevant after a window shrinks (e.g., is unmaximized) and another client becomes active. (Fixed in OpenBSD 6.1)

Enhancements

Preserve stacking order during cycling

cwm-restack.patch v3

After cycling through many windows, the original window may be obscured by many others, and if you still want to see its contents you end up doing the Alt-Tab-Tab-Tab-Tab-Tab, Alt-Tab, Alt-Tab dance.

This patch adds restacking of windows during cycling. Hold Alt, press Tab and a window will be raised. Press Tab again while still holding Alt and that window will be lowered back before another is raised. Once you release Alt, the original window will be hidden behind no more than one other (the target), assuming it was raised before.

Always keep clients visible

cwm-keep-visible.patch v3

cwm makes a client active only when the mouse pointer enters the window. Thus, once a client is off screen and another becomes active, it's lost forever.

This patch forces clients to overlap with at least one region (known as "CRTC" (or "output"?) to XRandR fans and "monitor" to normal people) when the client is moved or resized (or does it to itself). The client's region is:

• The region containing the centre point of the client;
• Failing that, the region that has the biggest overlapping area with the client;
• Failing that, the region closest to the client by Manhattan distance between edges.

When XRandR configuration changes, for every old region a matching new region is calculated using the algorithm above, and all clients within it migrate to the new region while preserving their relative positions. Full screen and maximized clients may change their sizes accordingly. Tiled regions may become no longer properly tiled.

Additionally:

• screen_area() was fixed and unused fields were removed from region_ctx
• Size hints are respected when creating a client
• Tiling commands now work on regions, not screens
• Bind commands migrateregion and rmigrateregion to move the current client between regions were added

Limitations: XSHAPE is not handled.

Don't clear urgency flag while cycling

cwm-cycling-urdency.patch v2

Don't clear the orange border signifying urgency (_NET_WM_STATE_DEMANDS_ATTENTION) from windows when Alt-Tabbing through them. Instead, do it when Alt is released within such window, or when the mouse is moved into it.

Code simplifications

cwm-simplify-ghoh.patch: Simplify group_holds_only_hidden(). (In OpenBSD 6.1)

cwm-simplify-toggles.patch: Simplify client_toggle_*(). (In OpenBSD 6.1)

cwm-minsize.patch: Remove redundant minimum client size adjustment. (In OpenBSD 6.1)
