* A Newcol refused because the panes' tags would not fit logs its err alone ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | and spends no column serial Newcol tries its column before keeping it: the new column is inserted, the panes' rows are shared out again, and where a pane would be left under its tag and two rows the column is taken back. The trial showed. insertColumn logged `newcol N` and the take-back `delcol N`, so a follower saw a column come and go around the err. Laying the column out also gave it a serial, so the next column made skipped one. The trial is now unannounced, since insert and drop have unlogged forms. A refusal puts the serial counter back where it was, after first giving every existing column its serial so the trial's is the only one spent. Only a column that stays is logged, and it gets the next serial. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A backward search along one long line takes time in the line's length, not ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | its square: ?a? over 117 KB goes from 6.4 s to 0.03 s The 9P fuzzer (seed 124) hung a session for over 5 s on `?a?` in a 117 KB file of one line. A backward search is every forward match up to the limit, so Regex.find ran once per match. Each call looked back from its start to the line's start, and forward to the line's end, over the whole line each time. That is quadratic, and the step budget, which counts only mvzr's steps, never saw it. find now keeps where it last learned a line starts and ends in the same text, and looks back only to there. The literal prefix's look back stops at the known part of the line. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* The ctl word name refuses a leading blank, as the name file doesGabriel Schneider5 days
| | | | | | | | | | `name /tmp/x` written to a pane's ctl trimmed the extra blank and named the pane /tmp/x. The same name written to the name file was refused with "a blank at its start", which fs.md gives as the rule, so the name a script wrote is the name it gets. The ctl word now hands the name file everything after its one separating blank. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Help and Find from the workspace or a column tag act in the session's ↵Gabriel Schneider5 days
| | | | | | | | | | | | directory, not the keyboard pane's New, Tty and commands clicked in a tag no pane owns ran in the session's directory, but Help named its +Help after the pane with the keyboard, and Find walked that pane's directory. So the same click gave different results depending on which pane was focused. Both now take the session's directory from a header, through execDir as the others do.

* A column's and the workspace's tag read with no trailing newline, as a ↵Gabriel Schneider5 days
| | | | | | | | | | | pane's does A pane tag read back its text alone, but a column tag and /tag appended a newline and gave a stat size one byte longer. So `$(cat tag)` agreed across the three kinds while `cat tag | wc -c` and a byte compare did not. All three now read the text alone, and fs.md says so.

* A builtin that takes no argument, written with one to an exec, is refused ↵Gabriel Schneider5 days
| | | | | | | | | | | | wrong #args as at a ctl At a ctl, `Config extra` and `DumpConfig extra` were refused with `wrong #args`. Written to an exec, the builtin match missed, since the word takes no argument, and the line ran as a shell command named Config, which did nothing and said nothing. An exec now refuses it with the ctl's words. A setting word keeps its value (`Verbose off`). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* acme's Tab, Indent, Local, Incl and Abort are refused as acme words pardes ↵Gabriel Schneider5 days
| | | | | | | | | | | | | has not, never run as shell commands The five were missing from the refused list, so at an exec or a ctl a typed `Indent on` fell through to the shell as a command named Indent. pardes has no equivalent for any of them: its tabs and indentation follow the file, commands always run in the pane's directory, and there is no include path or abort. They now get the same "invalid: acme's X is not a pardes builtin" as Zerox or Send. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | why, not a bare bad regular expression `^def|x` and `foo$|^zèbre` were refused with a bare "bad regular expression", the same words as a syntax error, so a script could not tell what to change. They now say "an alternation anchors every branch with ^ or none (^a|^b, not ^a|b)", through addr and Edit alike. fs.md states the rule and that a `$` does not count toward it (`foo$|bar` is fine).

* pardes NEWFILE in a pane forwards even when its directory is missing, and ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | Save makes the directories fs.md said FILE must already exist, while `pardes new.txt` in fact forwarded, making a pane named for it that Save creates. With a missing directory (`pardes notes/new.txt`) the launch gave up forwarding and started a nested editor inside the pane. Now the name is made absolute as written and forwarded the same way. A name written to a pane's name file that goes into a directory not there has its Save make the directories, as Config's pane does. A Save <path> into a missing directory still fails ENOENT. The Forwarding section now says what a new FILE does. fs.py launches one into a missing directory and saves it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* New and Tty run at /tagexec and a column's exec, and with no pane at allGabriel Schneider5 days
| | | | | | | | | | | | | The words New and Tty make a pane in the session's directory, and fs.md already has them run at a tag no pane owns. But /tagexec refused New as a pane's word, since the workspace tag does not hold it. Every header exec also failed ENOENT when no pane was left, and Tty gave up when it had no pane to take a directory from. Now New and Tty are every tag's words. A header exec with no pane runs at the stand-in, as a click in the empty window's tag does, and Tty with no pane asking starts in the session's directory, as New's scratch does.

* A word at /tagexec or a column's exec that makes, acts on and focuses no ↵Gabriel Schneider5 days
| | | | | | | | | | | | pane reads back nothing Newcol written to /tagexec read back `1`, the pane with the keyboard, which the word never touched. That was a pane word's fallback (a pane's exec answers the pane it ran at) applied to a tag no pane owns. A word in a column's or the workspace's tag now answers the pane it made, refilled, went to or focused, and otherwise nothing. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A failure naming a long path keeps its reason, and name refuses a component ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | over 255 bytes A Save of a 3000-byte path failed with the record "err 2 ctl: Save…", which lost the reason. The first cause was reportError, which formatted into 256 bytes, so the operation's path filled the buffer before the reason was written. The second was the waiting write's late failure, which took the first 256 bytes of the message row, never its end. Now reportError has room for the longest path. reportFailure also keeps the words fitted as an err is (fitErr: the path gives up its middle, the reason stays), and the late failure of a Save, a Dump, a shell or a ThemeFile takes those words. fs.md already said a name holds up to 255 bytes a component, but a longer one was taken and only failed later at Save. Now it is refused when written. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Nothing about a pane is logged before its new, and the boot terminal's new ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | carries the session directory, not / and a rename A pane named in the update that made it (Config's init file, a look renamed on open) logged `rename N <name>` before `new N`, so a follower met a serial it had never seen. The boot shell, started with no directory, was announced as `new 1 /` and renamed once its shell spoke. Now noteLog drops the rename of a pane not yet announced, since its new carries the name, and announces a pane first for any other record about it. A terminal whose shell has not said where it is is named by the session's directory, where it was started, and the shell saying so is no rename. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Column serials go on across a Restore as pane serials do: a restored column ↵Gabriel Schneider5 days
| | | | | | | | | | | | never takes a serial the old session handed out A Restore carried next_serial over for panes but started column serials at 1 again. So a restored column could take the serial a deleted column had, and a script holding col/<n> from before the Restore would find a different column there. The column counter is now carried over like the pane one, and restoredcol maps each old serial to a fresh one. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A control character in a write to any ctl file refuses the whole write, and ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | a refused line is quoted with its control bytes shown as blanks fs.md already promised that the whole of a write to /ctl, a pane's ctl and a column's ctl is checked first, as it is for exec and look. But a ctl write ran its lines one by one, so a line holding a control byte gave that line's own, misleading reason ("unknown command"). Worse, the reason quoted the raw byte back into the err record. The check now happens in tree.write before anything runs, with the same EINVAL and reason exec gives. A refusal's quoted line shows control bytes as blanks, so an err record never carries a raw escape. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Pane, column and workspace tags take one set of write checks, and a refused ↵Gabriel Schneider5 days
| | | | | | | | `>` write leaves the tag as it was A column's or the workspace's tag took any length, so a write past 4096 bytes went in and a later Dump failed on it (bad dump tag), and a truncating open wiped any tag before the write after it could be refused. The column and workspace tags now refuse what a pane tag refuses: the 4096-byte limit (ENOSPC, tag: no space: over 4096 bytes) as well as the control characters they already did. A truncation of any of the three is held until the write after it is known to fit, and done with it; a refused write drops it; a close or read with no write after it does it then (so `: > tag` still clears). A test runs a truncating write too long, a control character and a bare truncation at each kind, and Dumps after. docs/fs.md says so. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* An append to a body through 9P costs its own bytes, not five passes over the ↵Gabriel Schneider5 days
| | | | | | | | whole body: 60 KB appends go from 35.7 to 2.1 ms each Round 25 measured bulk body writes at about 8 ms a write. There is no frame wait in it: a profile of open, write, clunk in a loop found the flush of each close walking the whole body five times. dotOf, setDot and showOffset turned the cursor between offsets and rows by counting every newline from the top; setContent found the line index's changed span by comparing old and new byte for byte, and hashed the new text to see whether it was back to the saved one. The rows now come from the file's line index by binary search (checked against the counting at every offset), a splice tells setContent the span it changed, and the text is hashed only when its length is the saved text's. Measured over 9P on a Debug build: 60 KB appends 35.7 to 2.1 ms, 8 KB 5.3 to 0.8 ms, 1 KB 1.3 to 0.9 ms. What is left is two copies of the text an edit (the splice's and the undo snapshot's). The perf gate gains body-appends, 64 appends of 8 KB on the 50k-line file, and its three baselines are recorded again. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Config opens the startup file, DumpConfig the settings report, and the ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | workspace tag reads Dump Themes Config Debug Exit Config (SPC f c) opens init, found as the settings report finds it (opts.startup_config_path: $XDG_CONFIG_HOME/pardes/init or ~/.config/pardes/init, and the macOS and Windows paths config.md gives). A pane that already holds it is gone to instead; a file on disk is looked at; with none, an empty pane is named for it, and Save makes its directory and any above it first (File.make_dirs, fs.makeDirs) before writing. Without a configuration directory it says so and opens nothing. The report Config used to open, the startup path and every live setting, is DumpConfig, in a +DumpConfig pane. No alias keeps the old meaning. The workspace tag's default words put Themes where NextColor was, NextColor staying a builtin, and Config beside it. A tag the user edited is kept as it was: a dump stores only an edited one (topbar_custom), and a restore puts back only that. theme.snap types NextColor onto the workspace tag to click it, and tagnav's walk back to Dump takes five long-word steps. The rest of the re-recorded goldens differ in the workspace words and their widths only. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Terminal.zig is terminal.zig: a file of functions and no fields takes a ↵Gabriel Schneider5 days

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 <[email protected]>

| |/ / | | | | | | | | | | | | | | | | | | | | | pane under its tag and two rows, or is refused A seeded sweep of placements (New, pane/new, Edit =, Tty, look, Delcol, deletes, refusals included) over screens 6 to 40 rows high found no refused placement that leaves a pane short since lyltlqnz and lrpzwyom; the pane a row short came from Newcol, which halves a column's width so long tags wrap onto more rows, raising those panes' minimums with no rows moved. Newcol now shares each such column's rows out again, and where a column has not the rows for every minimum there is no new column (Newcol: no space for a column: the panes' tags would not fit), as a size too small is refused. The sweep, 300 seeds, is the test; a user's drag or a tag grown by editing may still take a pane under, as before. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | a write to pane/new, is its error alone, and every refusal is said in words The one-failure rule is a write's. A refused remove, pane/new's open refused for want of a slot, and an OTRUNC open's refused truncation (data's after a failed addr) also logged an err, and a reply carrying only an errno reached the client as the C library's text (Operation not permitted). tree.handle now gives such a reply Plan 9's words, chosen so 9ns maps each back to its errno (EPERM's to EACCES, as Plan 9's does), and serveFs logs errs for writes only, not a write to pane/new, which is only read. docs/fs.md and the 9P skill say so, and that a look miss quotes what was written.

It is now looked for whole, as zzq:2 already was, so every form's miss reads no match for "<as written>".

Rewriting the class before compiling, as ^a|^b already is, needs no mvzr patch; runes that differ only in their last byte go as one alternative (\xc3[\xa0-\xbf] for [à-ÿ]) so a 256-rune range fits the 512-operation limit, which counts the pattern as rewritten.

* | A ctl or exec line with no newline runs with its write and fails it, unless ↵Gabriel Schneider5 days
|/ | | | | | | | it needs more A last line with no newline was held to the close, so printf bogus > ctl answered 0 and failed only in the log, Edit ,s/zzz/y/ too. A write shorter than its Twrite is the whole of what was written (acme takes each write whole): its tail runs then and a failure is the write's. It is held only when the parser says it needs more -- an open { block, an a/c/i text -- or when the write filled its Twrite and may go on (the listener tells the core the room, msize less its header).

* Every catch unreachable, orelse unreachable and syscall assert outside tests ↵Gabriel Schneider5 days
| | | | | | | | is a real refusal or says why it cannot fire A sweep for round 23's crash: a run's answer (pty/run) was bufPrint'd into 48 bytes with catch unreachable, so a foreground program's long name (macOS gives up to 32 bytes) panicked; it now cuts at the room, keeping its newline, in 96 bytes. The rest were numbers into buffers sized for them, a braille codepoint, pthread calls on the queue's own mutex, and pdf_view's resolved outline entries: each now carries a one-line comment saying why it cannot fire.

* Delcol on the last column leaves the window, empty but for its workspace ↵Gabriel Schneider5 days
| | | | | | | | tag, as acme's does The last column's Delcol ended the session. The window now stays, with only the workspace tag; Newcol, and New (which makes the column it goes in), start it again. A word run with no pane at all runs with a stand-in that is no pane, the root ctl takes session words, and pane/new makes its scratch in the session's directory.

| | | | | | | | callers not found The ENOENT that 9ns reads from a failure's words came from a tacked-on suffix, grep: no match, not found, definition: nothing found, not found, no shell "x", not found. They now say it once: grep: pattern not found, find: name not found, Callers: callers not found, definition: not found, shell "x" not found (...). Co-Authored-By: Claude Opus 5.5 <[email protected]>
