aiongg 5654240729 refactor(cli): parse cadcraft-cli arguments with clap, following RFC-0012 (#2268)
* test(cli): pin today's command-line behaviour

The later commits change these tests on purpose, so each behaviour change shows in their diff.

* refactor(cli): split main.rs into modules, move only

- output: outln!, stdout state, atomic write, export helpers, view/window helpers
- args: USAGE, option validation, framing options, MCP argument parsing and its tests
- info, convert, sample, mcp: one subcommand each
- perf: synthetic drawing, Rng, perf subcommands
- run: run subcommand and {last} handle chaining
- main: crate docs, mod lines, install_io, open, main, cli, unit tests

No behaviour change.

* refactor(cli): typed errors and run(args, out, err)

cadcraft-cli is now a library plus a thin binary. `cadcraft_cli::run(args, out, err)
-> i32` is the whole program; main.rs only passes `args_os()` and the process
streams. Handlers write through a `Streams` wrapper (output.rs) instead of the
process streams; it keeps the closed-stdout semantics (drop later output, carry
on, a closed pipe is not an error, other write errors are reported once and make
the exit code 1). `mcp` still speaks MCP on the real stdin/stdout.

Errors are typed (thiserror): CliError (error.rs) wraps EngineError, DocError,
IoError, io::Error and the per-module WindowError, ArgsError, RunError,
OutputError and PerfError. `run` prints `error: {e}` and exits 1.

The usage text and the "unknown option/argument" messages stay as one
transitional CliError::Usage(String), printed without the `error: ` prefix.
USAGE stays a const; step 4 (clap) removes both. The engine's IoHooks take
`Result<_, String>`, so the three `.map_err(|e| e.to_string())` in install_io
remain. The hooks are set-once (OnceLock), so installing them on every `run`
call is harmless.

tests/it/usage.rs calls `run` in-process with Vec<u8> writers; the headless mcp
case runs through the binary (it reads the real stdin) and a non-Unicode
argument test is new.

Behaviour changes (old -> new):
- Every error line other than the usage-class ones gains the prefix `error: `
  (e.g. `--view needs ...` -> `error: --view needs ...`, `unknown command
  `x`` -> `error: unknown command `x``, `invalid parameters for `open`: ...`
  -> `error: invalid parameters ...`, `unsupported file type` likewise).
- `cadcraft-cli: cannot connect to HOST:PORT: e` -> `error: cannot connect to
  HOST:PORT: e` (the old prefix is replaced).
- A non-Unicode argument: panic, exit 101 -> `error: argument "..." is not
  valid Unicode`, exit 1.
- Unchanged: usage text, `X: unknown option --y`, `unknown option --y`,
  `mcp: unknown argument ...` (no prefix); warnings and `wrote ...` lines;
  the `cadcraft-cli: can't write to stdout: e` report; exit codes.

* refactor(cli): parse arguments with clap

Replace the hand-written parser (USAGE, validate_options, OptionSpec,
framing_option, parse_mcp_args, CliError::Usage) with clap derive types
in args.rs: a Cli parser and one Args struct per subcommand, with the
framing flags (--window, --view) in a FramingArgs struct flattened into
convert and run. USAGE's framing and --cmd chaining text moves into the
subcommands' and flags' doc comments and run's long help, so --help
carries it. `commands` moves from an inline closure to commands.rs.
`command()` exposes the clap definition for man pages and completions.

clap reads the arguments as OsStrings. Help and --version go to stdout
with exit 0; usage errors are clap's, on stderr with exit 2. A bare
--help or -h before `--` shows the subcommand's help even after a
mistake on the line (`run --script --help`). run opens its drawings
(FILEs, --sample, --metric) and runs its steps (--script, --script-file,
--cmd) in command-line order, from ArgMatches::indices_of. Values stay
strings checked by the handlers, with their messages and exit 1
(--window, --view, --cmd JSON, sample names, perf counts). The last of a
repeated flag wins (args_override_self on every subcommand but mcp).

Behaviour changes:

Help and version
- --help, -h, help: the USAGE page -> clap's help, first line
  "cadcraft-cli: headless CADCraft".
- bare cadcraft-cli: USAGE on stderr, exit 1 -> clap's help on stderr,
  exit 2.
- <subcommand> --help / -h, help <subcommand>: "unknown option --help"
  (exit 1), the USAGE page (convert, help <subcommand>) or a file named
  -h (info -h, run -h) -> that subcommand's help, stdout, exit 0.
- <subcommand> --version: "unknown option --version", exit 1 -> clap's
  unexpected argument, exit 2.

Usage errors (exit 1 -> exit 2, clap's messages)
- Unknown subcommand, empty subcommand, unknown top-level flag: USAGE ->
  "error: unrecognized subcommand 'foo'" / "error: unexpected argument
  '--bogus' found".
- Unknown flag on any subcommand: "info: unknown option --bogus",
  "unknown option --bogus", "mcp: unknown argument --bogus" or USAGE
  (convert) -> "error: unexpected argument '--bogus' found".
- A short flag where a file is expected (info -x): opened as a file ->
  unexpected argument; `--` before it keeps it a file name.
- A value flag at the end or followed by a flag (--window, --view,
  --script, --script-file, --cmd, --save, --export, --connect): "error:
  --script needs text" and the like, or the next flag taken as the
  value (--window --view, --script --sample, --cmd --sample,
  --script-file --sample) -> "error: a value is required for '--script
  <TEXT>' but none was supplied". --connect followed by an unknown flag
  (--connect --foo, --connect -v) names that flag instead (clap reports
  the unknown argument, not the missing value).
- mcp --connect with an empty value: "error: --connect needs HOST:PORT
  ..." -> "error: invalid value ' ' for '--connect <HOST:PORT>':
  expected HOST:PORT (...)"; --connect=-v likewise.
- mcp --connect twice: "error: --connect given more than once" ->
  "error: the argument '--connect <HOST:PORT>' cannot be used multiple
  times".
- mcp --lazy / --launch without --connect: "error: --lazy and --launch
  need --connect HOST:PORT" -> "error: the following required arguments
  were not provided: --connect <HOST:PORT>".
- Missing positionals (info, convert with 0 or 1 files, sample with 0
  or 1 arguments): USAGE -> "error: the following required arguments
  were not provided".
- Extra positionals: convert with three files (USAGE), and info,
  commands, perf, sample, which ignored the extra argument -> "error:
  unexpected argument 'extra' found".
- perf -5: opened as a file -> unexpected argument '-5'.
- A non-Unicode argument where text is expected: "error: argument ... is
  not valid Unicode", exit 1 -> "error: invalid UTF-8 was detected in
  one or more arguments", exit 2.

Accepted where they were errors
- --x=v is a spelling of --x v for every value flag (--window, --view,
  --script, --script-file, --cmd, --save, --export, --connect); before
  it was an unknown option or USAGE. A value starting with - needs the
  = form (--cmd=-x).
- commands --: "unknown option --" -> `--` ends the options (all
  commands listed).
- run --view extents --view current: "use only one of --window and
  --view" -> the last wins, like every other repeat.

Other
- run --sample --sample opens one sample drawing (was two): repeated
  flags are last-wins.
- run checks --window/--view values before opening any drawing, so a
  bad framing value is reported ahead of a missing file.
- `-h` after a mistake shows the long help (`--help`): the retry asks
  for --help.

Unchanged: --window with --view, framing without an image output,
--view's case-insensitivity, all value messages (--window numbers,
--view values, --cmd JSON, {last}, sample names, --script-file read
errors), multiple FILEs, --sample with --metric or a FILE, last-wins
for --save, --export, --window, --script/--cmd order, and `\n` in
--script.

clap forced: exit 2 for usage errors, its message wording, and the
unknown-flag-over-missing-value precedence above.

* refactor(cli): reject repeated flags, long version (photocraft#7071 decisions)

Behaviour changes, old -> new:
- --save, --export, --window, --view, --sample, --metric, --lazy, --launch given twice:
  last one won -> usage error, exit 2 ("the argument ... cannot be used multiple times").
  --connect was already rejected. --script, --script-file, --cmd and run's FILEs still repeat.
- --version / -V: "cadcraft-cli <version>" -> "cadcraft-cli <version> (<sha>)", sha from
  CADCRAFT_BUILD_SHA or "dev", as the desktop app prints it.
- "cadcraft-cli version" is an unrecognized-subcommand usage error (as before; now tested).
- A value starting with "-" needs the = form for every value flag (as before, tested).
  --window -10,-10,10,10 stays a usage error ("unexpected argument -1"); write
  --window=-10,-10,10,10. clap's allow_negative_numbers does not accept a comma list, and
  allow_hyphen_values would let --window swallow the next flag, so neither is set. The
  --window help text names the = form.

* refactor(cli): typed values and flag relations

Step 6 of #2228: values are parsed into their types and flag relations
are checked at parse time, so a bad value or combination is a usage
error (exit 2) naming the flag, before any work starts. The handlers
receive typed values only. Runtime failures (files, the engine, a
`{last}` with no earlier handle) stay exit 1.

- --window parses to a Bounds2 (parse_window plus cadcraft_io's
  check_window); its WindowError is the value parser's error.
- --view is a ValueEnum (extents, current), case-insensitive; the long
  help lists what each value does.
- --window conflicts_with --view. In run, --window/--view require
  --export (an ArgGroup "framing" with requires). A framing flag with
  an output that isn't an image (convert's OUT, run's --export) is a
  UsageError turned into a clap error by into_clap (ArgumentConflict).
- sample's name is a ValueEnum (bracket, floorplan); `floor` stays a
  hidden alias.
- perf's N|FILE is one typed positional: a value that parses as a
  count is one, clamped to 1..=20000000 as before (so `perf 0` still
  times one entity); anything else is a drawing.
- --cmd 'id {json}' parses to an id and a serde_json::Value (default
  {}); `{last}` is still filled in when the command runs.
- Paths are PathBufs (info FILE, convert IN/OUT, run FILEs,
  --script-file, --save, --export, sample OUT, perf FILE). The engine
  and io crates take file names as text, so a path that isn't valid
  Unicode is refused by the handler, naming the file (exit 1).
- Deleted: check_framed_output, the --view match, ArgsError,
  CliError::Window/Args/UnknownSample, RunError::CmdJson,
  PerfError::BadCount.
- run's FILEs, --sample and --metric still combine (each opens another
  drawing, the last is current): neither photocraft#7071 nor RFC-0012 requires
  otherwise.

Behaviour changes (old -> new):
- --window with a bad value (wrong count, not a number, NaN/inf,
  reversed corners, beyond 1e12): exit 1 `error: --window ...` ->
  exit 2 `error: invalid value 'V' for '--window <x0,y0,x1,y1>':
  <reason>`. The reasons no longer repeat the flag or the value.
- --view with a bad value: exit 1 `error: --view needs `extents` or
  `current`` -> exit 2 `error: invalid value 'V' for '--view
  <extents|current>'` plus clap's possible-values line.
- --window with --view: exit 1 `error: use only one of --window and
  --view` -> exit 2 `error: the argument '--window <x0,y0,x1,y1>'
  cannot be used with '--view <extents|current>'`.
- run --window/--view without --export: exit 1 `error: --window/--view
  need an image output ...` -> exit 2 `error: the following required
  arguments were not provided: --export <OUT.png>`.
- A framing flag with a non-image output: exit 1 `error:
  --window/--view only apply to image output (png, svg, pdf), not
  `OUT`` -> exit 2 `error: --window only applies to image output (png,
  svg, pdf), not `OUT`` (or --view: the message names the flag given).
- sample with an unknown name: exit 1 `error: unknown sample `X`
  (bracket, floorplan)` -> exit 2 `error: invalid value 'X' for
  '<bracket|floorplan>'` plus the possible values. sample's help lists
  the possible values.
- --cmd with JSON that doesn't parse: exit 1 `error: --cmd ID:
  <serde error>`, after the earlier steps ran -> exit 2 `error: invalid
  value 'V' for '--cmd <id {json}>': <serde error>`, before anything
  runs.
- --cmd with an empty id (`--cmd=` or `--cmd ' {}'`): exit 1 `error:
  unknown command `` ` -> exit 2 `... expected a command id, then
  optionally its JSON parameters`.
- An empty path argument (info "", sample bracket "", perf "", ...):
  exit 1 from the engine or io -> exit 2 `error: a value is required
  for '<FILE>' but none was supplied` (clap's PathBuf parser).
- A path that isn't valid Unicode: exit 2 `error: invalid UTF-8 was
  detected ...` -> exit 1 `error: PATH: the file name is not valid
  Unicode` (text values that aren't Unicode stay exit 2). A non-Unicode
  --save or --export is refused before any drawing opens.
- perf's help gives the count range.

Tests: usage.rs rows above moved to exit 2 with clap's messages; new
rows for --view with a non-image output, run's framing with a dxf
--export, an empty --cmd id, bad --cmd JSON after a good step, a
`{last}` with no earlier handle, --window beyond 1e12, case-sensitive
sample names and empty paths. The non-Unicode test covers both a path
(exit 1) and text (exit 2). Unit tests: the --window parser tests moved
to args.rs; new ones for --cmd values and perf targets; framing_options
checks the clap error kinds.

* refactor(cadcraft): move launch-argument parsing into launch_args

Moves the hand-written parser (the argument loop, control_port_from, control_flag and their tests) from main.rs into launch_args.rs, which returns LaunchArgs. No behaviour change.

* refactor(cadcraft): parse launch flags with clap (RFC-0012)

Replaces the hand-written loop in launch_args.rs with clap derive types, as photocraft's launch_args.rs does. --help is generated from the doc comments and lists the other CADCRAFT_* variables.

Behaviour changes (old -> new):
- An unknown flag (--sampel) was opened as a file; it is now a usage error on stderr, exit 2, before the window opens. A file starting with "-" goes after "--".
- A repeated --control or --sample was accepted (last wins); it is now exit 2.
- A bad port (--control abc, 70000, -1) was logged and the control channel left off; it is now exit 2. The same for CADCRAFT_CONTROL_PORT, and the error names the variable when the value came from it.
- A bare --control (no value) kept CADCRAFT_CONTROL_PORT's port with a warning; it is now exit 2 ("a value is required"). A following flag is never taken as the value.
- An empty or blank CADCRAFT_CONTROL_PORT was logged as a bad port; it is now unset.
- --control=7979 is accepted (the equals form was opened as a file before).
- --version / -V and --help stop parsing at once and exit 0; version text is unchanged ("cadcraft <version> (<sha>)").
- -psn_* (Finder process serial number) is dropped instead of opened as a file.
- A file name that is not valid Unicode used to panic in std::env::args(); it is now read from args_os and reported with a log warning, not opened, because CadApp::open_path takes text.

Copied from photocraft's crates/automation/src/args.rs: blank_env_is_unset and name_env_vars unchanged (name_env_vars gets a local use for ContextKind/ContextValue); control_port and NotAPort unchanged. allow_negative_numbers is set on --control as in photocraft, so -1 is a bad value rather than a missing one.

* feat(cli): shell completions and man pages

Adds examples/man-and-completions.rs, which writes cadcraft-cli's bash, zsh, fish, elvish and
PowerShell completions (clap_complete) and man pages (clap_mangen: cadcraft-cli.1 and one per
subcommand) into a directory. clap_complete and clap_mangen are dev-dependencies, so the binary
is unchanged.

packaging/linux/package.sh builds the example in its own cargo run, runs it (through $EMULATOR
for cross builds; warns and leaves the files out without one) and installs the man pages and the
bash, zsh and fish completions into the staged tree. nfpm.yaml already ships the whole
usr/share tree, so it needs no change.

CADCraft has no FreeBSD packaging, so there is no FreeBSD script to update. macOS and Windows
packaging are untouched.

tests/man_and_completions.rs checks the generated file names.

* ci(cli): check the command-line code with ast-grep (RFC-0012)

Adds ast-grep rules from RFC-0012, run by craft-common-actions'
reusable ast-grep workflow (Linux, no Rust build, path-filtered):

- clap-error-message: a string literal, format!, .to_string() or
  SCREAMING_CASE const passed to Command::error / Error::raw
- clap-error-message-variable: the same message built into a variable
  first, in the same function
- string-error: Result<_, String>, Err(format!(..)), Err(".."),
  Err(x.to_string())
- args-os: std::env::args(), which panics on non-Unicode arguments

Scan paths: apps/cadcraft-cli/src, apps/cadcraft/src/launch_args.rs,
apps/cadcraft/src/main.rs. Rule tests run first in CI.

Source: photocraft#9750 at d16686cd. Only the scan paths and the
workflow path filters differ from it.

Fixes: none needed. The rule tests pass (4 passed) and the scan finds
nothing in the scanned paths.

* docs(cli): cadcraft-cli page, following RFC-0012

docs/cli.md: --help is the reference; exit codes, streams, usage
errors, values starting with -, paths, completions and man pages; the
environment variables (none for cadcraft-cli, CADCRAFT_CONTROL_PORT for
the desktop app's --control); and the rules not followed yet, with the
reason. The README links it.

* feat(cli): refuse an output that replaces an input

RFC-0012 rule 1.6: nothing destructive by default.

Behaviour change: `convert a.dxf a.dxf`, `run a.dxf … --save a.dxf` and
`run a.dxf … --export a.dxf` used to overwrite the input. They are now a
usage error (exit 2, `error: …` on stderr, nothing opened or written)
unless `--in-place` is given. "Same file" is file identity (same-file
crate), so `dir/./a.dxf` and a symlink to the input count. An output
that does not exist, or a failed identity check, is not refused; the
open or write reports the real error. Replacing an existing file that
is not an input is still allowed.

Scope: `--save` and `--export` only. A save that a --cmd or script runs
(for example `saveas`) is the engine's and is not checked.

Every write the CLI makes (convert OUT, --save, --export, sample OUT) resolves
an existing output first, so writing through a symlink updates the file it
points to and the link stays a link; the atomic rename used to replace the
link with a regular file, leaving the target (with --in-place, the input)
unchanged.

* feat(cli): --compact for JSON output

RFC-0012 rule 1.3: info and commands pretty-print their JSON by
default; --compact prints it on one line. run prints one JSON line per
--cmd result (JSON lines, one result per step), as its help and the
README document, so it takes no --compact. mcp's stdout is the MCP
protocol and is unchanged.

Behaviour change: info and commands accept --compact (it was an
unknown flag, exit 2). Their default output is unchanged.

docs/cli.md says which subcommand prints which form, and lists perf's
text table (no --json) and saves a --cmd or script runs (not checked
by --in-place) under "Not followed yet".

* fix(cadcraft): one Switch parser for boolean environment switches

CADCRAFT_VSYNC, CADCRAFT_SYSTEM_CURSOR, CADCRAFT_WAYLAND and
CADCRAFT_NO_NATIVE_MENU each had their own idea of "on". They now share
cadcraft_ui_egui::switch::Switch: 1/on/true/yes is On, 0/off/false/no is
Off (case- and space-insensitive), unset or blank is Default, and any
other value is Default and logged with the variable name. The ENVIRONMENT
help text says the same for all four.

Behaviour changes (old -> new):
- CADCRAFT_WAYLAND=0 counted as on (any value did); now only On keeps
  native Wayland.
- CADCRAFT_NO_NATIVE_MENU=0 counted as on (any value did); now only On
  keeps the menus inside the window.
- CADCRAFT_SYSTEM_CURSOR treated every value except ""/0/false/off as on;
  now only the On spellings do, and an unknown value is logged.
- CADCRAFT_VSYNC is unchanged except that an unknown value is logged.

* fix(cli): keep paths as paths until a file is opened

A path is now text only where text is needed.

- cadcraft: FileNames.unreadable is Vec<PathBuf>, logged with {:?}
  (escaped bytes) instead of a lossy rendering.
- cadcraft-cli: unicode() is called only inside open(), the one place
  that sends a path to the engine as JSON. convert, sample and run
  --save/--export pass the output as &Path. write_atomic, export,
  export_framed and OutputError::Write take or hold a Path/PathBuf;
  errors use .display(), and the `wrote ...` line uses .display().
- Dropped the dead find_subcommand lookup in launch_args (LaunchArgs has
  no subcommands).
- docs/cli.md: non-Unicode names are refused only where a drawing is
  opened.

Behaviour change: an output name that is not valid Unicode used to be
refused (exit 1); it is now written under that exact name. Opening such
a drawing is still refused.

Lossy strings that remain (all feed APIs that take text and only look at
the extension, never at the path the bytes are written to):
- cadcraft_io::write / write_framed (name picks the format) in sample.rs
  and output.rs::export_framed;
- cadcraft_io::is_image in convert.rs, run.rs and args.rs (framing flag
  check);
- cadcraft_engine::cmd::file::drops_unknown in export_framed.
These go away when cadcraft_io and the engine take impl AsRef<Path>
(the A1 follow-up). A non-Unicode extension is not a known format either
way, so it is rejected as an unsupported type, as before.

* refactor(cadcraft): read the environment once into Env

The desktop app reads its CADCRAFT_* variables once at startup into
apps/cadcraft/src/env.rs `Env` and passes the values on; no library crate
reads a CADCRAFT_* variable at run time any more.

- One `VARS` table (name, help line) feeds both the reader and the
  Environment section of `cadcraft --help`. A test checks that every
  variable the reader asks for is in the table, that every table entry
  sets a field, and that the help lists every entry.
- vsync goes to `gpu::surface_config`, the system cursor to
  `CadApp::set_system_cursor_default` (Options reset and Reset Palettes go
  back to it), FONTALT/FONTFALLBACK to the `cadcraft_fonts::ttf` setters
  (re-exported as `cadcraft_engine::fonts`), the settings directory to the
  new `cadcraft_engine::settings_dir::set`, and to `Workspace::load`.
- The three copies of the settings-directory rule (main.rs, workspace.rs,
  the engine's plotter folder) are one: `settings_dir::platform`.
- `Switch::from_env` is gone; `Switch::parse` stays.
- The child-process tests for CADCRAFT_CONTROL_PORT are replaced by tests
  that inject the variable lookup (`blank_env_is_unset`) or point
  `--control`'s fallback at PATH.

cadcraft-cli: plotter configurations matter to its output (`run --cmd plot`
or a script's PLOT with a user device, and the same through `mcp`), and the
font variables change how convert/run/sample draw text. So, following
RFC-0012 rule 1.7, the variables become fallbacks of flags declared with
`env =`: --config-dir (CADCRAFT_CONFIG_DIR), --fontalt (CADCRAFT_FONTALT)
and --fontfallback (CADCRAFT_FONTFALLBACK) on convert, run, mcp and sample.

Behaviour changes:
- CADCRAFT_CONFIG_DIR set but empty counts as unset everywhere: the
  workspace file and the plotter folder use the platform folder (was:
  workspace persistence and the plotter folder off). Logs and autosave
  already treated it so.
- The workspace file and the plotter folder ignore a relative
  XDG_CONFIG_HOME, as logs and autosave did (was: used it).
- A blank CADCRAFT_LOCALE means the system's languages (was: [""]).
- cadcraft-cli: the three variables apply only to convert, run, mcp and
  sample, as flag fallbacks (was: read by the engine and fonts in every
  subcommand, perf included). A font variable that isn't valid Unicode is
  a usage error naming the flag (was: ignored).

* refactor(io): one Format enum for file extensions

`cadcraft_doc::Format` (re-exported as `cadcraft_io::Format`) is the one
place that maps a file name's extension to a format: Dxf, Dwg, Dwt, Svg,
Svgz, Png, Pdf. `from_path` is ASCII case-insensitive; no extension (or a
trailing dot) is Dxf; an unknown extension is None. `READ` and `WRITE`
list the formats `read` and `write` accept. It lives in cadcraft-doc
because the engine depends on cadcraft-io only for tests.

Each place used to match on its own lower-cased extension string and now
matches on Format, with the same results:
- io::read: svg/svgz -> SVG reader, dxf/none -> DXF reader, other ->
  try DXF, else Unsupported(ext).
- io::write_with: dxf/none -> DXF, dwg -> DWG bridge, other with binary
  -> error, rest -> write_framed.
- io::write_framed: dwt -> DWG; dxf/none/dwg -> write_with; svg, png,
  pdf -> image writers; other -> Unsupported(ext).
- io::is_image: svg, png, pdf (not svgz, which is read only).
- engine file.rs is_dxf, drops_unknown (dwg, dwt), is_drawing_file
  (dxf, dwg, dwt, none).

Behaviour change (help text only): the CLI help lists the formats from
Format::READ / Format::WRITE instead of hand-written lists. `info` and
`convert IN` now name svg and svgz as readable, and `convert`, `sample`,
`run --save` and `run --export` name dwt (and `sample` pdf) as writable.
A test checks each file argument's help names every format of its list.

* refactor: one version string for the app and the CLI

cadcraft_engine::build_version() builds "<version> (<commit>)" once; the
desktop app's --version, its start-up log line and cadcraft-cli --version
all use it. No change in output.

* refactor(cli): share the environment helpers with the CLI

Move blank_env_is_unset and name_env_vars from the desktop app into
cadcraft_mcp::args and apply them in the CLI parser.

Behaviour changes (old -> new):
- Empty or blank CADCRAFT_FONTALT / CADCRAFT_FONTFALLBACK: reached clap as
  Some("") -> counts as unset.
- A bad value from an environment variable: the error named the flag ->
  names the variable.
- CADCRAFT_CONFIG_DIR is unchanged: empty still means no settings folder.
- Desktop app: unchanged; it uses the shared helpers.

* refactor: pass paths, not text, through io, engine and open_path

cadcraft_io::{read, write, write_with, write_framed, is_image}, the engine's
drops_unknown/is_drawing_file/read_text_file and CadApp::open_path take
paths (impl AsRef<Path> / &Path). The desktop launch arguments and the CLI
no longer convert paths to text to call them.

Behaviour changes (old -> new):
- A dropped file whose name is not valid Unicode opened with a "can't
  read" error naming a mangled path; it now opens natively. (Its path is
  not remembered for QSAVE, which then asks where to save.)
- A launch argument that is not valid Unicode was logged and skipped; it
  now opens like any other.
- A .dwt export builds the .dwg name as a path, not formatted text.
- On the web, a non-Unicode path passed to open_path reports "the path
  is not valid Unicode" instead of a lossy name.
- Opening errors print path.display().

FileNames and LaunchArgs::file_names are removed; the launch tests assert
the parsed PathBufs. New io test: non-Unicode names pick the format by
extension.

* docs(cli): CADCRAFT_CONFIG_DIR is the one flag fallback where empty isn't unset

* fix(engine): refuse a drawing path that isn't valid Unicode

read_file opened such a path with no saved path, so QSAVE could not save back to it.
It now returns an open error naming the file before reading it. The ui-egui opener
already reports read_file errors like any other failed open.

* fix(cli): report a failed write of help or version

A write error on help or version output (other than a closed pipe) now exits 1 and
tries to say so on stderr; it was ignored and exited with the clap code. A closed pipe
keeps the clap exit code.

* fix(cli): --connect needs HOST:PORT

--connect example.com was accepted and failed later. It is now a usage error (exit 2)
unless the value is a non-empty host (or a bracketed IPv6 address) and a u16 port.
The host is not resolved.

* docs(cli): run prints no line for a command with no result

* refactor(cli): explicit imports and smaller functions for the stricter lints

Lints: clippy::wildcard_imports, too_many_arguments, cognitive_complexity (30).

Replaced the non-test `use super::*;` in args, commands, convert, info,
output, perf and run with explicit imports; lib.rs keeps only the imports
its non-test code uses, and its test module imports the rest itself. The
`super::*` in the test modules stays.

A clippy run with all three lints and threshold 30 reports nothing in
apps/cadcraft-cli or in code this branch added, so no function needed
splitting.

Nicholas Gower 1c7d3f0fae CLI: a --cmd can act on a handle an earlier --cmd returned ({last}) (#1871)
* cli: act on a handle an earlier --cmd returned ({last}) (#1663)

A run's --cmd steps were independent: mview answered {"viewports":["100"]}
but viewport.set could not use that handle, so it failed with "no viewport
given".

The batch runner now remembers the last object handle a --cmd returned (the
strings in its result that name an entity of the active drawing, so counts and
names are not mistaken for handles). A parameter value of exactly {last} in a
later --cmd, at any depth, is replaced with it; every other value is passed
through unchanged. With no handle yet the run fails with a clear error instead
of passing a bad handle to the command.

Fixes #1663

* cli: keep {last} to the drawing and handle fields that returned it

Read handles only from result handle fields, never arbitrary strings: a group named like another object's handle is a name, not a reference. Clear the remembered handle when new, open, document.switch (or a script running one) makes another drawing current, and keep a handle the new drawing's own command returns.

8166e4a809 AutoLISP: load and run .lsp routines (fixes #758) (#855)
* AutoLISP: load and run .lsp routines (#758)

CADCraft runs AutoLISP routines. `.lsp` files load with APPLOAD, (load)
or by dropping them on the window, and at startup from the support folder
(acad.lsp once per session or per drawing with ACADLSPASDOC, acaddoc.lsp
per drawing, then S::STARTUP; never from a drawing's own folder).
(defun c:NAME …) defines commands, (autoload) defers loading to first
use, and (expression) and !variable work at the command line and at
prompts. docs/autolisp.md lists what is supported.

The interpreter (crates/engine/src/lisp) reads source with its own
stack and evaluates on an explicit-stack machine, so a routine can stop
for input (getpoint, pause in command) and carry on later on one thread,
deep recursion is an error rather than a crash, and long loops run a
slice per frame (Esc stops them). It follows AutoLISP: 32-bit wrapping
integers, dynamic scope, *error*, vl-catch-all-apply, AutoLISP's error
wording. About 200 built-ins cover the language, command (with pause and
commands left open), entity lists (entget/entmake/entmod/entdel/entlast/
entnext/handent, through the DXF reader and writer's groups, exposed by
cadcraft-io and handed to the engine through a hook), ssget with modes
and filters, tables, system variables, get… input with initget, and
units. A routine is one undo step; each drawing has its own symbols.

Also: keywords typed as _KEYWORD match at prompts; TEXT run by a
routine's command takes one line; DIMENSION records carry their
measurement (42); Prompt::raw shows a get… prompt as written; the
interface asks Session::prompting() (a command's or a routine's prompt)
where it asked whether a command runs, so clicks, right-click and Delete
work at a routine's prompts; getcorner and based get… prompts drag a
rubber band.

Tests: the language, errors, startup files, interactive input, hostile
input (lisp/tests.rs); the #648 corpus, 18/18, when CADCRAFT_LISP_CORPUS
points at it (tests/lisp_corpus.rs); drop, frames and canvas clicks in
the app (ui-egui/tests/lisp_files.rs).

* AutoLISP: bound memory, drop nested values iteratively, guard the per-frame tick

- Cons cells drop with a work list over both car and cdr (and function
  bodies), so a list nested a million deep in its car no longer overflows
  the stack when it goes away.
- Memory caps so a runaway routine fails with a LISP error instead of an
  uncatchable out-of-memory abort: at most 5,000,000 live cons cells
  (counted in Value::cons / Drop, checked every step; cells the drawing's
  variables already held at the run's start don't count against it), no
  string a built-in makes longer than 8 MiB (strcat checks before joining,
  printed text is cut), and a 2 GiB per-run budget for new strings,
  printed text and files read.
- Session::lisp_tick runs under catch_unwind, and so does every slice of
  the LISP machine: a panic ends the routine with "internal error", puts
  the drawing back and leaves the session usable.
- Regression tests for each (deep car nesting, nested functions, the cell
  cap, string length and budget, a panicking built-in in a blocking run
  and in a ticked one).

aldozarandClaude Opus 5.5 483a9304ca cadcraft-cli mcp: --lazy and --launch for clients that start before the app (#756)
MCP clients start their servers when they start, usually before CADCraft is
open, and `--connect` refuses to start then. `--lazy` starts the bridge
anyway and reaches the app at the first tool call; until the app answers,
each call fails with how to open it. `--launch` (implies --lazy) opens
CADCraft on macOS with that control port at a call that finds nothing, and
waits up to 30 s. Neither falls back to a headless session (#103).

Valentin KleinandClaude Opus 5.5 89799f48d4 Keep raster images through DXF save; report entities a save can't keep (#208) (#217)
Raster images: the reader now follows an IMAGE's group 340 to its IMAGEDEF
and keeps the file path and the definition's name (its ACAD_IMAGE_DICT
key), pixel size and resolution unit. It also keeps the clip boundary (in
pixel coordinates), the clipping state, the display flags and
brightness/contrast/fade. The writer emits the IMAGE entity, plus one
IMAGEDEF per path and name, an IMAGEDEF_REACTOR per image,
RASTERVARIABLES, the ACAD_IMAGE_DICT and ACAD_IMAGE_VARS entries in the
named object dictionary, and the four CLASS records, as the DXF Reference
describes. An image without a clip boundary gets the full-image rectangle.
DWG save keeps the same data, except the resolution unit, which the DWG
bridge drops. The pixels are still not loaded.

Entity types CADCraft doesn't model (MLINE, MULTILEADER, 3DSOLID, REGION,
MESH, ...) are still not written. Writing their raw groups back into the
R2000 file would leave references to objects that aren't kept
(MLINESTYLE, MLEADERSTYLE, ACIS data in later versions), and some of the
types don't exist in R2000 at all. Another CAD program could then reject
the whole file. Instead, qsave, saveas and document.bytes now say on the
command line which ones weren't saved ("Not saved (CADCraft can't write
these object types yet): 1 3DSOLID, 2 MLINE") and list them by type in the
result's `notSaved`. `cadcraft-cli run --save` and `convert` print the
same line.

cyfung1031 8b13fa3b17 fix(cadcraft-cli): reject unknown options (#120) 2026-10-10 12:26:40 -04:00
Valentin KleinandClaude Opus 5.5 396b098d9a CLI: image exports honour the current view and take --window/--view (fixes #165) (#170)
`convert` and `run --export` always fitted the model-space extents, so
`zoom`, `pan` or `view.set` in a run had no effect on the image and there
was no way to export a region.

- io: `write_framed(d, name, window)` frames PNG, SVG and PDF on a
  model-space rectangle (fitted without margin, centred, no distortion);
  `write` is unchanged and still fits the extents. `check_window` rejects
  non-finite, inverted, zero-size and out-of-range (±1e12) windows.
- CLI: `run --export` shows the current view when the commands changed
  it, otherwise the extents as before. `--window x0,y0,x1,y1` and
  `--view extents|current` on `convert` and `run` choose the framing
  explicitly. The usage text and README say how images are framed.

* cadcraft-cli mcp: --connect without HOST:PORT is an error, not a headless session (#103)

`mcp --connect` with no address (or an empty or flag-like one) fell through
to the headless backend, so a client meant for the app got successful edits
in a separate drawing. The mcp arguments now go through parse_mcp_args:
--connect must be followed by a non-empty value that doesn't start with `-`,
unknown arguments and a repeated --connect are rejected, and every error
exits non-zero before any MCP request is served. Plain `mcp` is still
headless; a real address still connects, and an unreachable one still fails.

- Unit tests for the parser; integration tests (tests/mcp_connect.rs) run the
  binary: missing/empty/flag-like address, headless control, loopback
  endpoint routing, closed port.
- docs/mcp.md says what happens without an address.

Valentin KleinandClaude Opus 5.5 7666c1cd68 LINE: deferred tangent/perpendicular for the first point (fixes #69) (#168)
TAN and PER snaps need the other end of the line, so the first point of a
LINE (no base point yet) could never snap tangent: a belt line tangent to
two circles was impossible to draw.

Now, as in AutoCAD, a point prompt can accept *deferred* snaps:

- snap: with no base and the new `deferred` flag, osnap offers "Deferred
  Tangent" (circles, arcs) and "Deferred Perpendicular" (circles, arcs,
  lines, xlines, rays) where no other snap wins. The hit carries the curve
  (`SnapHit::deferred`, `Deferred`, `SnapCurve`).
- `resolve_deferred` solves the line once the other end is known: tangent
  or perpendicular from a point, tangent-to-tangent (common tangents of two
  circles, new `Circle::common_tangents` in geom) and the perpendicular
  mixes. Among several solutions the one nearest the picks wins. No
  solution (point inside the circle, concentric or nested circles,
  non-finite input) is `None`, never a panic.
- prompt: `Prompt::deferred()` opts a prompt in; `Input::Deferred` reaches
  only such prompts, everywhere else the session turns it into the point it
  was picked at, so other commands snap as before.
- LINE opts in for its first point (and the next one while the first is
  still deferred). No solution reports and re-prompts; Undo drops the
  deferred point. The rubber band shows the resolved line, also the
  tangent-to-tangent one while hovering the second curve
  (`Session::cursor_deferred`, set by the canvas).
- canvas: passes the prompt's flag to osnap and sends a deferred pick as
  `Input::Deferred`.
