* Symbols, Diagnostics and every language server list share their directory's ↵Gabriel Schneider4 days
| | | | | | | | one +Search Only Find and Grep reused the directory's +Search; a language server's list made another pane of the same name each time. Every origin named +Search now shares it, but a plain word's search, which keeps a list a pattern for n/N to walk between. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pattern with a newline and an anchor mvzr would misread is refused EINVAL, ↵Gabriel Schneider4 days
| | | | | | | | as the doc says Its words named no malformed input, so 9ns read the refusal as EIO, and Edit's failed EIO directly. It now says bad regular expression: ..., and Edit's failure with those words is EINVAL too. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A look at a corrupt image fails with an err rather than open a blank paneGabriel Schneider4 days
| | | | | | An image stb_image could not read opened as an empty image pane, the look succeeding. The bytes' header is now checked at the look (stbi_info_from_memory), and one that is no image it reads fails the look, look: <path>: not an image pardes can read, making no pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A PDF's body reads the text layer of the page it showsGabriel Schneider4 days
| | | | | | The body of a PDF pane read as empty. It now reads MuPDF's text extraction of the page shown, the text search and n/N already use, read-only (a write is refused, as round 22's body refusal made it). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Back or Forward over a closed file deleted since skips it and goes on, saying soGabriel Schneider4 days
| | | | | | A jumplist entry for a closed file no longer on disk tried to reopen it, failed as a look, and left the step stuck there. Its entries now go, the message row says <path>: deleted, skipped, and the same step is taken over what is left. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A clamped Recent range ends at a line's last character, never swallowing its ↵Gabriel Schneider4 days
| | | | | | | | newline A range past the end of a file that had shrunk was clamped to the empty line after its final newline and to one past a line's last character, so the selection took the newline in. Its ends now clamp to the last line and to its last character, as addr's L:C does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A look miss said again is its err record counted, as any repeated err isGabriel Schneider4 days
| | | | | | Look's miss pushed its err record plain, so a script retrying one look filled the log with the same line, where other errs are counted (x2). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A language server question that finds nothing, cannot be answered or has no ↵Gabriel Schneider4 days
| | | | | | | | room fails, and so does a write to an image's or PDF's body Callers or Callees with nothing found, Hover or Lspwhy with no room for its pane, and a question asked of no file's pane said nothing, the 9P write succeeding; a body write to an image or PDF pane went nowhere. A write that asks a language server now waits for its answer (turn.lsp_answers), and what fails there -- nothing found, no answer, a backend's @none why, a placement with no room (ENOSPC) -- fails the write and logs its err. No diagnostics is said, not failed. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A builtin or setting this build lacks is refused GUI-only, from an exec tooGabriel Schneider4 days
| | | | | | On a terminal, Fonts written to an exec was no builtin there, so it ran as a shell command and ended exit 127; ctl said unknown control message. Both now say Fonts is GUI-only, invalid here (a builtin another platform's build has, not in this build). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Theme takes a name in any case, and a miss names its nearest themesGabriel Schneider4 days
| | | | | | Names were case-sensitive, and a miss listed only the first letter's themes that fitted 40 bytes, 4 of the many d ones. It now lists every theme sharing the first letter when they fit the 128 bytes an Rerror carries, else the nearest by a plain likeness score (shared prefix, the name inside, its letters in order). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Dump into a DumpDir that is no directory says so; the doc says a missing ↵Gabriel Schneider4 days
| | | | | | | | last directory is made DumpDir /dev/null said no such directory though it is there, and the doc claimed a missing DumpDir always fails, where its last component is made at the Dump. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Recent keeps only files on disk, and its cap never drops an open oneGabriel Schneider4 days
| | | | | | A renamed scratch never saved and a /virtual/ pane were recorded as recent files, and at 200 the oldest entry went even when that file was open. Opens, renames and closes now record a path only when it is a file on this host, and the cap drops the oldest closed entry. A name with a newline is not written to the kept list, where it would read back as two. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* get's refusal over unsaved text logs its unsaved record, as the other ↵Gabriel Schneider4 days
| | | | | | | | refusals do Exit, Restore, Del and Delcol log unsaved <serial> <name> before their err; get logged only the err. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* /recent shows a name as /index does, a newline in it escapedGabriel Schneider4 days
| | | | | | It printed paths raw, so a name holding a newline read as two rows. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pty/ctl exec that cannot start its shell keeps the one runningGabriel Schneider4 days
| | | | | | Each host closed the running shell before it forked the new one, so an exec whose shell failed left the pane with none and later runs answered error shell gone. A shell not there is now refused up front, and every host starts the new shell first, replacing the old only once the close-on-exec pipe says it ran; a failure there is only said (restartFailed). Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A script whose interpreter is not there is told apart from a missing shell, ↵Gabriel Schneider4 days
| | | | | | | | and Tty refuses it up front Tty's up-front check found the script and let it through, so the pane was made, its exec failed ENOENT, and the log read new, msg shell: shell not found, del, then the err. The check now reads a script's #! line and refuses it, interpreter /no/such/interp not found, and an exec that fails ENOENT on a file that is there says the same. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A look at a ./ or ../ name that is not there names the file, not the pane's ↵Gabriel Schneider4 days
| | | | | | | | directory Any relative name that opened nothing was blamed on the pane's directory (look: .../work/many: no such directory) though it exists; the directory is named only when it is gone. A plain name is still looked for as text, its miss logged as any look's. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Find or Grep that finds nothing empties its directory's +SearchGabriel Schneider4 days
| | | | | | It failed with no match but left the last search's rows in the +Search, where they read as this one's. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A repeated identical search reads back the +Search it left as it wasGabriel Schneider4 days
| | | | | | When a Find or Grep found exactly what its +Search already held, the pane was kept but not marked as the one the search touched, so the exec read back the pane it ran in. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A directory's +Search is found by its directory, the pane that ran the ↵Gabriel Schneider4 days
| | | | | | | | search included Find and Grep passed over the pane they ran in when looking for the +Search to fill, so a Grep written to a +Search's own exec made a second one, and the two swapped roles on each run after. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* One reopen of a closed file is that file's pane in every jumplist entryGabriel Schneider4 days
| | | | | | A Back that reopened a file updated only the entry it stepped onto; another entry for the same file stayed closed, and stepping onto it re-looked the file, found it already active and returned without moving, so Forward (or Back) did nothing. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A remembered place is clamped to the file as it is now, its selection's two ↵Gabriel Schneider4 days
| | | | | | | | ends kept A Recent row or a jumplist entry for a line the file no longer has failed the look; now it opens at the last line. The selection's anchor is remembered too, so a reopen restores both ends where they fit, and Recent and Jumplist share the (closed) marker. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A refusal over unsaved panes keeps its list in +Unsaved and shows a short noticeGabriel Schneider4 days
| | | | | | | | | | | Exit's refusal (and Restore's, Del's, Delcol's, get's) put its full text on a notice that went: a long list of names, gone before it was read. The list now goes into one +Unsaved pane, filled again by each refusal, a row a pane (`<name>: Modified`) and the `Exit again to discard` line; the notice is short, `3 unsaved panes — Exit again to discard`. The 9P `unsaved` records and the write's err are as they were. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* ThemeSel is Themes and FontSel is Fonts; the old words still work in init ↵Gabriel Schneider4 days
| | | | | | | | | | | | files and dumps The user asked for the plainer words. Every use is renamed: the builtins, leader paths, /commands, the docs and tutor, tests, and the themesel golden, re-recorded. An init file's ThemeSel or FontSel runs the new word and says `ThemeSel: renamed to Themes`, as ColumnTags is said; a dump naming an output pane by the old word restores it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Recent lists the files opened lately, closed ones too, and a jump back to a ↵Gabriel Schneider4 days
| | | | | | | | | | | | | | | | closed file reopens it A file closed by accident, its path forgotten, could not be found again: the jumplist dropped closed panes. Every file opened (a look, a Save of a scratch, a Restore, a rename) goes first in a list of 200, kept once, its dot noted when it closes, kept across sessions in $XDG_STATE_HOME/pardes/ recent. `Recent` (SPC f r) shows it in a reused +Recent, each row `path:line:col open|closed` a look reopens; /recent reads `open|closed <path>`. The jumplist keeps a closed file's entries, +Jumps marks them `(closed)`, and Back to one opens the file at its place. acme has no such thing; its dump and Load are the nearest. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A column takes panes until their minimums fill it, not until none can be halvedGabriel Schneider4 days
| | | | | | | | | | Placement halved the tallest pane or refused, so 11 panes filled 48 rows that hold 16 at their tag and two rows each: the refusal did not match the documented arithmetic. When no pane can be halved but the minimums with the new pane's fit, the column's rows are shared out again; and a refused pane's removal leaves no pane under its minimum. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Find and Grep share one +Search a directory, each run replacing the lastGabriel Schneider4 days
| | | | | | | | | Each Grep with a new pattern opened another +Search, until the column refused panes. Find and Grep now reuse their directory's one, as acme reuses +Errors, and the exec reads back the pane it filled; a plain word's LookWord list search keeps a pane a pattern as before. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Errnos that fit: a Dump into a missing DumpDir and a shell that is not there ↵Gabriel Schneider4 days
| | | | | | | | | | | | are ENOENT, a GUI-only setting EINVAL A Dump into a DumpDir not there failed EIO `file not found`; `no shell "x"` read as EIO through a mount; and a GUI-only setting on a terminal, EINVAL in the reply, had no word 9ns reads as EINVAL. Each says so in the words that give its errno: `no such directory`, `not found`, `invalid here`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A bad event record says what is wrong with itGabriel Schneider4 days
| | | | | | | | `bad event syntax` said nothing of which: now it says a report record (I D i d) is not written back, a range ends before it starts, or what a record looks like when the line is not one. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A test: a malformed address is bad address syntax, EINVAL, on a terminal as ↵Gabriel Schneider4 days
| | | | | | | | | on a text Round 20 reported a malformed address on a terminal answering otherwise; it answers `bad address syntax` here, as on a text pane, and this holds it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A ctl line that ran and failed is not quoted after its reason; only one ↵Gabriel Schneider4 days
| | | | | | | | | | | | refused before running is Failures of a builtin through a ctl quoted the line after the builtin's own words, which already named it (`Mount dead /x: dial failed: no answer "Mount dead /x"`), while the same failure through exec did not. A line that ran says why in its own words everywhere now; only a line refused as no message at all quotes it, as Plan 9's cmderror does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A name shows its own backslash as \\, and a terminal tag never carries a raw ↵Gabriel Schneider4 days
| | | | | | | | | | | newline With `\n` for a newline and `\xNN` for a bad byte, a name holding a backslash and an n read back as one holding a newline. Names in /index, the log and a terminal's tag now double their own backslashes; and a terminal's directory with a newline no longer breaks its tag. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A tag write refuses NUL and the other control characters; a Dump that fails ↵Gabriel Schneider4 days
| | | | | | | | | | | | says so A NUL written into a tag went into the dump, which the host then could not write, and Dump said nothing: a success that wrote nothing. Tag writes, the workspace's, a column's and a pane's, refuse control characters but tab and newline, DEL, C1 and bytes not UTF-8, EINVAL; and Dump reports any failure of its own instead of swallowing it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A served-tree pane spoils no Grep, and `look .` from a gone directory is ENOENTGabriel Schneider4 days
| | | | | | | | | | | A pane named `/virtual` gave Grep the root `/`, which swallowed every other pane's directory and ran out of walk before any file: every Grep missed. Grep passes over panes of the served tree. And `.` from a pane whose directory was gone resolved to the served tree's root (/virtual/), or through the jump list to another pane's directory: a dot path is the looking pane's own, and gone it fails, `look: <dir>: no such directory`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* /index shows names as the log does, one line of UTF-8, and a newline in a ↵Gabriel Schneider4 days
| | | | | | | | | | | | name as \n /index printed a name as it was, so a directory with a newline in it split its row in two, and bytes not UTF-8 went through; the log turned the newline into a space, silently another name. Both now show a name one way: a newline `\n`, other controls, DEL and C1 a space, bytes not UTF-8 `\xNN`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Every EINVAL a write gets says why; DEL in an exec or look line is a control ↵Gabriel Schneider4 days
| | | | | | | | | | | | character An empty name, a word written to log other than follow, a data, sel, dot or dirty write to a pane with no text, a truncate other than to zero, and a control character in a look line written through a held open were refused with no words, logged as `Invalid argument`. Each says its reason now; and DEL is refused in exec and look lines as in names. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* pty/ctl exec fails the write when the shell cannot start; a directory ↵Gabriel Schneider4 days
| | | | | | | | | | | | | removed under a shell leaves its name `exec` on pty/ctl restarted a shell in a directory that was gone, the write succeeding and the pane dead; and the pane was then renamed `<dir> (deleted)` from /proc, so a restart failed even once the directory was back. `exec` is now refused up front, ENOENT, where the directory is gone; a shell the host cannot start fails the waiting write (late failure, as a Save's); and a `(deleted)` cwd is no name to take. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pane's word written to /tagexec or a column's exec is refused, not done at ↵Gabriel Schneider4 days
| | | | | | | | | | | the focused pane Undo, Msg and the other pane words written to a tag no pane owns ran at whichever pane had the keyboard. They are refused as the root's ctl refuses them, EINVAL; the tag's own words (a column's New, Tty, Find, Grep) still run. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A command from a missing directory fails ENOENT with no pane; one whose ↵Gabriel Schneider4 days
| | | | | | | | | | | | | shell never started ends exit 127 Exec made a command pane in a directory that was not there, whose shell never started: it said running for ever, a follower waited for an exit that never came, and Kill found it. The line now fails up front, as Tty does, `exec: <dir>: no such directory`; and a command pane whose shell the host could not start ends `exit 127` at once. A shell that could not start in its directory says `directory missing`, not `file not found`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A shell given a directory is not taken to be in this process's before it has ↵Gabriel Schneider4 days
| | | | | | | | | | | | | spoken, so it logs no rename to the session's and back Each host read /proc/<pid>/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. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A terminal is typed into only when idle at an empty promptGabriel Schneider4 days
| | | | | | | | | A look at a directory, or an exec at a terminal, typed its line after whatever sat unsent at the prompt and ran the two joined (`echo TYPEDls`). A terminal with text at its prompt now takes no line; a look at its directory opens a new terminal, an exec runs as a command pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Grep and Find count the rows they found, so a hit opens its +Search and a ↵Gabriel Schneider4 days
| | | | | | | | | | | | miss fails Round 18 made a search that found nothing fail, but grep and find never counted their rows (only a pane search did), so every Grep read as a miss. Both count the lines they wrote now; a Find or Grep that finds nothing fails alike, `find: no match, not found` / `grep: ...`, ENOENT, and opens no empty +Search. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A new terminal is named by its directory from the start, so its shell ↵Gabriel Schneider4 days
| | | | | | | | | | arriving there is no rename Tty's terminal was `new N /` until its shell reported its directory, then `rename N <dir>`: a rename for no change of place. The pane owns the directory it is started in from the first; only a move elsewhere renames. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A builtin failure over something not there answers ENOENT: Unmount of a name ↵Gabriel Schneider4 days
| | | | | | | | | | not mounted `Unmount nothere` failed EIO with `not mounted`. It says `no such mount nothere` now, and a builtin's failure that says `no such` (this, Tty's `no such directory`) answers ENOENT, the errno 9ns reads from those words. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Grep with no hit says grep: no match, and a pane directory that is not there ↵Gabriel Schneider4 days
| | | | | | | | | | | is passed over Grep walks every pane's directory; one not there (a scratch named into a directory not made yet) failed the whole search with `file not found`. Such a root is passed over now, and a search that finds nothing says `grep: no match` and opens no empty +Search. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A builtin that needs its argument, written bare to an exec, is EINVAL as ↵Gabriel Schneider4 days
| | | | | | | | | | through ctl Through a ctl the bare word was refused up front (EINVAL); through exec it ran, failed with EIO or asked for the argument. The exec now refuses it the same way before it runs. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* get on a pane of a peer out of reach says dial failed, as look and Save doGabriel Schneider4 days
| | | | | | | | get's failure named the path and `cannot be read` for any error but a missing file; a peer that did not answer now reads `get: <path>: dial failed: no answer`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A rename alone does not make a pane dirtyGabriel Schneider4 days
| | | | | | | | | Any rename marked the pane dirty (saved revision one back), while the guards ask only whether its text was ever edited: /index said dirty for a pane Exit let go without asking. The name is no edit now, so /index, the guards and Restore agree; Save writes under the new name all the same. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* The root exec's refusals before a line runs name the pane, and say invalid, ↵Gabriel Schneider4 days
| | | | | | | | | | | so a mount reads EINVAL A line over 1024 bytes or with a control character was refused with its errno EINVAL but words 9ns reads as EIO (no `invalid` in them), and logged `err - exec`. They now say `invalid command line: ...`, and the root's err record names the pane the line would have run at. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* `@p<terminal>:N` past the terminal's last line is a miss, as in a fileGabriel Schneider4 days
| | | | | | | | The line-past-end check read only a file pane's lines, so a terminal's look went nowhere and said nothing. A terminal's lines are its logical lines, as a +Search of it lists them. Co-Authored-By: Claude Opus 5.5 <[email protected]>
