Same treatment the landing page got, across README, docs/, and both manpages (\(em included). 2026-09-02T13:09:36Z user user@clank 2026-09-02T13:09:36Z urn:sha1:cafa48e0a7e1eb48a783bfde6862c5fd82c7aede The +x+y offset goes -- 'N clients' says the thing that matters. The inverse-video chip goes with it: the tag now draws in attach_fg / attach_bg from the theme, defaulting to gray ink on the terminal's own background. Standing information, not an announcement. 2026-09-02T13:03:53Z user user@clank 2026-09-02T13:03:53Z urn:sha1:1a3ba183ae8f2613cae847c8f6460782512acc40 A small tag in each client's own top-right corner when several terminals share the session: the viewer count, and on a view that is a crop being panned by somebody else's cursor, the crop's offset into the shared screen ("2 clients +12+4") -- which is exactly the moment a screen moving on its own needs explaining. Stamped per client after projection, because every terminal has its own count of others and its own offset; the shared status bar is composed once and can be cropped out of a panned view anyway. attach_indicator false hides it. 2026-09-02T12:57:13Z user user@clank 2026-09-02T12:57:13Z urn:sha1:d698946464f25a0eb43730ffad15656f3247f56b The patch made shared attach unconditional; these make it a policy. multi_attach false restores the classic displacing attach (EXIT_REPLACED, which old clients already understand). size_follows picks whose size the shared screen takes: active (the patch's rule), smallest (the tmux rule: filler, never a crop), or largest. The size fold lives in apply_canvas, so any attach, resize or departure can move the canvas under the folding policies -- including a non-active client leaving, which under smallest may have been the very client holding the floor down. A config reload re-applies both knobs to the running session. 2026-09-02T12:51:02Z Ingmar Steen iksteen@gmail.com 2026-08-31T12:43:32Z urn:sha1:29061a4aca5e3d645c0e23b885342036ac48f97b Last input wins, canvas size is adjusted to active connection. 2026-09-02T12:43:09Z user user@clank 2026-09-02T12:43:09Z urn:sha1:18d1aef0f9bf4620135fd9f77f26683e6f2f8c00 The static musl release builds cannot dlopen -- musl compiles it out -- so loadable shader plugins were a feature most shipped binaries could not use. Nothing we ship used it either: every shader in contrib/shaders is an expression. Gone: the dlopen/glob loader in shader.c, shader_dir in the config, the plugin ABI table and entry macro, the Windows dl*/glob shims that existed only for it, the contrib/shader-plugin skeleton, its tests, and every doc mention. shader_abi.h stays as the shader model (cell_t, shade_ctx_t, shader_t) with a note about what it used to be. 2026-08-28T12:41:42Z Peter Geissler peter@haxx.in 2026-08-28T12:41:42Z urn:sha1:2fbd36c1cef6ea6c9fcf9c36afb5209089288257 Windows has no VEOF. The console driver does not know the character, so ^D arrives at cmd.exe and PowerShell as an ordinary keystroke and they ignore it -- it even echoes, which is how you find out: the line reads `echo hello^D`. The one key that closes a pane on every other platform does nothing at all, and closing a pane becomes a word you have to type. That you can type `exit` instead is the tell: the intent was never ambiguous, only unspoken. So slosh speaks it. What goes to the pane is the word, not a signal and not a close from outside -- the shell runs its own cleanup, returns its own status, and keep_dead decides what is left behind, all three of which reaching past it would skip. It is also what the user would have typed, so there is nothing new to explain. The knob is what makes it honest, because a wrong guess costs a pane. It fires only with the shell itself in the foreground (a program that is running may want the EOF for itself -- `cat` reading to end is the whole job), only on the primary screen (in an editor or a pager ^D is half a page down, and the alternate screen is the pane stating that rather than us matching process names), and only on an empty line (POSIX sends EOF there; what it does not do is discard what you typed). The line is an estimate. The shell's editor is on the far side of a pty, so pane_send_key counts what it forwarded since the last Enter. Editing it does not model -- a recalled history entry, ^U, completion -- leaves the count too high, which forgets to exit. That is the direction to be wrong in; the other one throws away a half-typed command. Default true on Windows, false on POSIX, where the line discipline already does this and does it properly: ^D there is also EOF for `cat` and every REPL, none of which is ours to intercept. A knob rather than an #ifdef so the guards are the same code everywhere and can be tested where the test suite runs -- test_ctrl_d.py turns it on and drives all four decisions, plus the case that does exit. Telling trapped from forwarded needs a program that reports what it received: on POSIX a forwarded ^D also ends an idle shell, and looking for the word `exit` cannot separate them either, because bash prints `exit` itself on EOF. Verified on the Windows box as well, where it is the default: ^D at an idle cmd.exe prompt takes the pane (and with it the session, having no panes left), `more` in the foreground keeps its own EOF, and a half-typed line survives with the line still on screen. 2026-08-27T13:27:51Z user user@clank 2026-08-27T13:27:51Z urn:sha1:b5df6a7b1d73fc9740a077e8eca2d7fc8f6afe60 Section 5 is where unix keeps its file formats, and slosh has two documents sharing one syntax -- the configuration and the layouts -- so they share a page the way they share a parser. docs/slosh.5 covers the KDL subset, where the file lives and how reload refuses a broken one, include and its precedence, every top-level setting grouped the way config.md groups them, the theme block, the shader vocabulary with the expression language summarised, the states and their ranking, the keys block including direct bindings, and the layout schema (tab, pane, and their properties). Held to the source like slosh.1 before it: every name in config.c's KNOWN_TOP -- the list the loader refuses unknown settings against, itself held to the loader by test_config.py -- must appear in the page, so a knob cannot be added without this page hearing about it. The pair must cross-reference each other, and both must be pure ASCII and lint clean under groff -ww. slosh(1) grows a SHADERS section -- the one feature a synopsis reader would never guess a multiplexer had -- and its SEE ALSO now names slosh(5) and nothing else: the other multiplexers can advertise themselves. Install puts the page under share/man/man5, the release tarballs carry both pages, and the Homebrew formula installs what the commit it is building has, guarded as before.
