pardes.git/src/panes.zig, branch release-0.24

A look at a directory opens a pane listing it, as acme's directory window: named dir/, its entries in acme's columns (bytewise, dotfiles kept, a directory's marked /), a look at an entry from there, Get or a look again reads it again, never dirty, Save refused; DirLook terminal keeps ls in a terminal

A +Pager pane whose text is a diff is drawn and looked at as a diff, as a diff command pane is: git diff, show and log -p page into review

2026-10-01T04:35:12Z

With git paging into +Pager, a diff arrived as plain text: no colour for its sides and a right click on a hunk line searched the word. A +Pager pane now notes, as its text is set, whether its first 64 KiB holds a diff header or a unified hunk, and such a pane takes the diff highlighting and the diff look every diff pane has.

A command run from a pane gets acme's $winid, the serial of the pane it was run from; one from a column's or the workspace's tag gets none

2026-10-01T03:12:18Z

PARDES_PANE names the command pane itself, so a script a click ran had no way to address the pane it was run in, as acme's win scripts do with $winid. The command pane now remembers that pane and its child gets winid set to it; a header tag's command, which no pane owns, gets winid unset. PARDES_PANE is unchanged. Co-Authored-By: Claude Opus 5.5

Terminal.zig is terminal.zig: a file of functions and no fields takes a namespace's lowercase name

2026-10-01T03:12:17Z

The last of the deferred renames, now that the tty and theme agents have landed: panes.terminal at its importers, the alias lines in Text.zig and File.zig and panes.zig's own uses following. dump.zig's Terminal struct, a dump record, is not this. The served sources list and docs/design.typ name the new file. test/perf.zig's references change, so the three perf baselines take its new harness id with their numbers as recorded. No behaviour changes. Co-Authored-By: Claude Opus 5.5

Mini.zig is mini.zig: a file of functions and no fields takes a namespace's lowercase name

2026-10-01T03:12:17Z

The naming the split agreed on, deferred until now; panes.mini is its name at its importers. File.zig keeps its alias line (const Mini = panes.mini) so the file another agent is working in changes by that line alone. The served sources list and docs/design.typ name the new file. No behaviour changes; test/perf.zig's two references change, and since the perf harness is keyed by its own text, its three baselines are recorded again (under other agents' builds, so a little slower).

A shell that cannot start fails Tty and pty/ctl exec with why, before either answers

2026-10-01T03:12:16Z

A shell whose exec failed (a script's missing interpreter) was reported started: Tty and pty/ctl exec succeeded, then the pane died. The child now reports a failed chdir or exec through a close-on-exec pipe the parent reads before acknowledging the shell; the host's spawn fails with the reason (`shell not found`, ENOENT), which fails the waiting write. A Tty whose first shell never ran leaves no pane; a terminal restarted by pty/ctl exec keeps its pane. Co-Authored-By: Claude Opus 5.5

A shell given a directory is not taken to be in this process's before it has spoken, so it logs no rename to the session's and back

2026-10-01T03:12:16Z

Each host read /proc//cwd right after forking the shell and at every frame after; before the shell's chdir that says this process's directory, a rename to it, then the real one a frame later, a rename back. A shell given a directory is named by it already (newShell) and is no longer asked at fork; and until it has printed anything, an answer naming this process's directory is not taken.

Tty in a missing directory fails and makes no pane; a shell that never started answers runs

2026-10-01T03:12:16Z

The host could not start the shell (its chdir failed), and the pane stayed with no pty: a run written to it waited for a prompt for ever. Tty now refuses a directory that is not there, `Tty: : no such directory`, before making a pane; and a terminal whose shell the host could not start (Pardes.shellFailed, from each host's spawn) answers any run with `error shell gone`.

A send to Python's REPL runs once, the Enter after the paste, not in it

2026-10-01T03:12:15Z

A one-line send (print(1)) to Python 3.14 stopped at ... and needed another Enter: its REPL takes a bracketed paste, and an Enter read in the same read as the paste is part of the paste, one line or not (checked in a real pty). Into a REPL that asked for bracketed paste, the Enters (two for an open block) now wait for its next output, its answer to the paste, or 250 ms with nothing. fs-test runs python3 in a real pty and checks a one-line exec prints at once; the docs' pty/data recipe says to send the Enter apart.

Del and Delcol refuse unsaved text once, as acme's do

2026-10-01T03:12:15Z

acme's Del asks winclean first and Delcol colclean (exec.c del, delcol): unsaved text is warned about, and the same word again closes. pardes closed at once. Both now refuse once through the one-warning-per-word mechanism Exit uses, from keys, tags, exec and ctl alike. A pane dirty only by a rename, or an empty one that never held a file, has no text to lose and is not asked about, and a scratch or a command's output under 100 bytes is not either, as acme's winclean passes a small unnamed window.
