# Command line
|
|
|
|
The reference below is taken from the program's own `--help`. If the two
|
|
disagree, the program is right and this file is a defect.
|
|
|
|
## Synopsis
|
|
|
|
```sh
|
|
nuntius [--version] [--check-config]
|
|
```
|
|
|
|
With no flags, nuntius loads the configuration, serves the form endpoints,
|
|
and shuts down gracefully on SIGINT or SIGTERM.
|
|
|
|
## Global flags
|
|
|
|
| Flag | Effect |
|
|
|---|---|
|
|
| `--help`, `-h` | prints the usage |
|
|
| `--version` | prints the release and exits: the tag at a tag, a pseudo-version naming the commit otherwise, `(devel)` outside version control, `+dirty` appended on a dirty tree |
|
|
| `--check-config` | loads and validates the configuration, then exits without listening; prints `configuration OK: <path>` on success, names the problem and exits nonzero on any error, so it runs as a systemd `ExecStartPre` |
|
|
|
|
Every flag is long-only, and Go's `flag` package accepts it with one or two
|
|
leading hyphens, so `-version` and `--version` are the same flag.
|
|
|
|
## Environment and files
|
|
|
|
`NUNTIUS_CONFIG` moves the configuration file away from
|
|
`/etc/nuntius/config.toml`. The full schema lives in
|
|
[`CONFIGURATION.md`](CONFIGURATION.md).
|
|
|
|
## Exit codes
|
|
|
|
| Code | Meaning |
|
|
|---|---|
|
|
| `0` | the version was printed, the configuration is valid, or the server shut down cleanly |
|
|
| `1` | the configuration is missing, invalid or fails validation, or the server failed to serve |
|
|
|
|
## Examples
|
|
|
|
Print the release:
|
|
|
|
```sh
|
|
nuntius --version
|
|
# nuntius v1.0.0
|
|
```
|
|
|
|
Validate a configuration without listening, as a deploy pipeline would:
|
|
|
|
```sh
|
|
NUNTIUS_CONFIG=./config.toml nuntius --check-config
|
|
# configuration OK: ./config.toml
|
|
```
|
|
|
|
## Manual page
|
|
|
|
A roff copy of this reference ships as `man/nuntius.1` in the repository
|
|
and installs with the binary; read it with:
|
|
|
|
```sh
|
|
man ./man/nuntius.1
|
|
```
