Close the 3 gaps between "builds in the repo" and "installs from a tarball
like Go", so writeonce can ship to other developers.
- VERSION file at repo root single-sources the toolchain version (0.1.0).
- `woc version` -> "writeonce 0.1.0 linux/amd64"; `wovm --version` -> "wovm
0.1.0" (stamped by the Makefile from VERSION; --version handled only in the
plain-wovm path so a built app never shadows its own `version` arg).
- wo.toml `[runtime] wo = ">= X.Y"` is now ENFORCED: woc refuses a project
requiring a newer toolchain than itself (>= and bare version parsed;
unknown operators accepted forward-compatibly). Was parsed-and-ignored.
- woc self-locates wovm: --runtime > [build] runtime > $WO_RUNTIME > a `wovm`
beside the woc binary (Sys.executable_name) > runtime/wovm rel CWD. An
installed woc in <prefix>/bin finds its sibling wovm from any cwd.
- `just dist` (scripts/mkdist.sh) packages writeonce-<ver>-linux-amd64.tar.gz,
Go-shaped (archive root writeonce/, bin/{woc,wovm}, README, VERSION), with a
drift guard asserting VERSION == woc == wovm. dist/ gitignored.
- `just install-accept` (scripts/install-accept.sh) is the gate: extract, PATH,
version, build+run a project from an unrelated cwd, constraint refusal — 6/0.
Verified: install-accept 6/0; woc-test 565/0; wovm suites + cli_smoke;
log-watcher 7/0. Linux-amd64 only (a cross matrix is future work).

writeonce @VER@ (@TRIPLE@)
A single-binary compiled language with an embedded, WAL-durable database. This
archive is the toolchain: woc (the compiler) and wovm (the runtime VM).
Both are native binaries that depend only on the system C library — nothing
else to install.
Install (Linux)
Remove any previous install and extract this archive into /usr/local,
creating a fresh /usr/local/writeonce:
rm -rf /usr/local/writeonce && tar -C /usr/local -xzf writeonce-@VER@-@TRIPLE@.tar.gz
(Run as root, or through sudo.)
Add /usr/local/writeonce/bin to your PATH by adding this line to your
$HOME/.profile (or /etc/profile for a system-wide install):
export PATH=$PATH:/usr/local/writeonce/bin
Restart your shell, or source $HOME/.profile to apply it now. Then verify:
woc version # writeonce @VER@ linux/amd64
wovm --version # wovm @VER@
Use
woc <project-dir> # builds <project>/target/<name>, one standalone binary
./<project>/target/<name> # run it — no runtime to install on the target host
A writeonce project is a directory with a wo.toml manifest and one or more
.wo files. woc locates wovm beside itself, so a tarball install needs no
extra configuration; override with the $WO_RUNTIME environment variable or a
[build] runtime = "..." key in wo.toml if you ever need to.
A wo.toml may declare a minimum toolchain version:
[runtime]
wo = ">= @VER@"
woc refuses to build a project that requires a newer toolchain than itself.
