Major refactor: monorel no longer requires being run from the module root.
It now accepts paths to binary packages from any ancestor directory and
walks up from each path to find go.mod (groupByModule / findModuleRoot).
Binaries sharing a module root are grouped together. When the script must
cd into a module directory (multi-module run or different CWD) the per-module
output is wrapped in a bash subshell to prevent directory leakage.
The .git stop-marker now only triggers on a .git DIRECTORY, not a .git FILE.
A .git file means the path is inside a submodule whose real repository root
is further up the tree, so the search continues upward.
Any directory on the path from the module root to a binary that
contains its own go.mod is a separate module; monorel should not try
to manage it. Two cases are now caught with distinct errors:
../other → "outside the module directory"
./cmd/go.mod → "has its own go.mod" (intermediate dir)
./cmd/foo/go.mod → "has its own go.mod" (binary dir itself)
Both suggest the correct fix: cd into that directory and run monorel
from there.
The tool now requires at least one positional argument — the path(s) to
the Go main package(s) to build — and must be run from the module root
(the directory containing go.mod).
# single binary (module root is the main package)
monorel .
# multiple binaries under one module
monorel ./cmd/gsheet2csv ./cmd/gsheet2tsv ./cmd/gsheet2env
Changes:
- Add `binary` struct {name, mainPath} and `parseBinaries()`
- "." is special-cased: binary name is taken from the CWD, not "."
- filepath.Clean's "./"-stripping is undone so goreleaser sees an
explicit relative path (./cmd/foo not cmd/foo)
- `goreleaserYAML` now takes `projectName + []binary`
- Each binary gets its own `builds` entry (with `id:` and `main:`)
and its own `archives` entry (with `ids:` to link it to the build)
- `main:` is omitted when mainPath is "." (goreleaser default)
- Checksum is named <projectName>_VERSION_checksums.txt
- `printScript` takes `projectName + []binary`
- Summary line says "Binaries:" (plural) when more than one
- Upload step globs tar.gz + zip for every binary, then the checksum
- Require go.mod in CWD; error out with usage message when no args given
Also regenerates cmd/tcpfwd/.goreleaser.yaml via the new code path
(adds `id: tcpfwd` to builds/archives; no functional change otherwise).
Adds a standalone Go CLI tool (tools/monorel) that automates the
goreleaser + gh release workflow for modules living in a subdirectory
of a monorepo where goreleaser Pro is not available.
Run from any module subdirectory (e.g. cmd/tcpfwd):
monorel # writes .goreleaser.yaml + prints release script
monorel --help # (flag defaults)
What the tool does:
- Detects module path and binary name from git prefix
- Lists and semver-sorts tags matching <prefix>/v* (e.g. cmd/tcpfwd/v*)
- Computes version: exact tag → stable release; commits/dirty → pre-release
- Writes (or updates) .goreleaser.yaml with the binary name hard-coded,
{{.Env.VERSION}} used for filenames instead of the prefixed tag,
and release.disable: true (gh handles the GitHub Release)
- Prints a numbered bash script covering env vars, optional git tag,
goreleaser build, release notes, and gh release create/upload/publish
Also updates cmd/tcpfwd/.goreleaser.yaml (first output from monorel):
- Fixes stray trailing quote in ldflags
- Sets release.disable: true (was release.footer)
- Adds generated-by header comment
- connEntry.isIdle(now, threshold): caller supplies now instead of time.Since
- connRegistry.closeIdle(now, threshold): passes now through to isIdle
- trackingConn gains a clock func() time.Time field used in Read/Write
- handleConn takes clock func() time.Time; uses it to init lastRead/lastWrite
and passes it to trackingConn
- Call sites in main pass time.Now or time.Now() explicitly

On SIGINT/SIGTERM:
- Stop accepting new connections
- Close connections idle longer than --idle-timeout (default 5s),
determined by LastRead/LastWrite timestamps tracked per connection pair
- Wait for active connections to drain up to --shutdown-timeout (default 30s)
- Force-close any remaining connections if the timeout is exceeded
Also switches isClosedConn to use errors.Is(err, net.ErrClosed) and
exits the accept loop cleanly when a listener is closed during shutdown.

Accept any number of local-port:remote-host:remote-port forwards as
positional arguments. Backward-compatible with existing --port/--target
flags. Adds --version/-V/version and --help/help handling matching the
auth-proxy pattern, including printVersion printed to stderr at startup.
