项目历史

xwininfo belongs to the classic X11 application/tool set rather than to a separately branded application lineage. Its current X.Org README describes it plainly as a program that prints information about windows on an X server, with primary development in the xorg/app/xwininfo repository and questions directed to the Xorg mailing list.

The public cgit history shows the modern standalone module rooted in X.Org's early-2000s source imports: an X.Org baseline commit in 2003, XFree86 vendor imports in 2004, modular build-system work in 2005, and X11R7 packaging updates as X.Org split the monolithic tree into independently released modules.

Because xwininfo's job is to interrogate X server window state, its history follows X11's debugging culture: small tools such as xwininfo, xprop, xev, xlsclients, and xdpyinfo expose protocol and window-manager details that desktop users normally never see.

采用历史

xwininfo is widely packaged because it is basic X11 diagnostic equipment. Distributions ship it either as its own X.Org app package or as part of grouped X utilities; users reach for it when they need a window id, geometry, root-window data, child tree, or details for scripting around X clients.

Its adoption persists even as Wayland desktops grow, because Xwayland, remote X11, legacy window managers, CI display tests, and old Unix desktops still need simple command-line inspection of X windows.

使用方式

Without an id or name, xwininfo lets the user click a target window and then prints default stats. Common scripted forms include `xwininfo -id 0x...`, `xwininfo -root`, `xwininfo -tree -root`, `xwininfo -name TITLE`, and `xwininfo -all` for a broader dump.

The manpage documents options for children/tree traversal, geometry and size, bits, events, window-manager hints, shape extension data, root-window inspection, and integer-vs-hex window ids.

为什么软件包爱好者会关心

xwininfo is a package-nerd staple because it is one of the smallest ways to see the X server's model directly. It turns invisible protocol objects into text, which makes it useful in packaging tests, bug reports, shell scripts, window-manager debugging, and support docs.

It also illustrates the X.Org modularization story: a once-monolithic X utility became an independently versioned app module with its own repository, releases, and downstream package recipes.
