Logging Policy - -- Do not introduce excessive logging in hot paths. -- Do not log sensitive data. -- Preserve existing log levels and style. - -### 17. Pre-Response Verification Checklist - -Before producing the final answer, verify internally: - -- The change compiles conceptually. -- No unresolved symbols exist. -- All modified call sites are updated. -- No accidental behavioral changes were introduced. -- Architectural boundaries remain intact. - -### 18. Atomic Change Principle -Every patch must be **atomic and production-safe**. -* **Self-contained** — no dependency on future patches or unimplemented components. -* **Build-safe** — the project must compile successfully after the change. -* **Contract-consistent** — no partial interface or behavioral changes; all dependent code must be updated within the same patch. -* **No transitional states** — no placeholders, incomplete refactors, or temporary inconsistencies. - -**Invariant:** After any single patch, the repository remains fully functional and buildable. - diff --git a/Cargo.toml b/Cargo.toml index dbdb024..fd1d892 100644 --- a/Cargo.toml +++ b/Cargo.toml @@ -1,6 +1,6 @@ [package] name = "telemt" -version = "3.0.12" +version = "3.0.13" edition = "2024" [dependencies] diff --git a/Dockerfile b/Dockerfile index 2725aac..7abe548 100644 --- a/Dockerfile +++ b/Dockerfile @@ -40,4 +40,4 @@ EXPOSE 443 EXPOSE 9090 ENTRYPOINT ["/app/telemt"] -CMD ["config.toml"] \ No newline at end of file +CMD ["config.toml"] diff --git a/src/main.rs b/src/main.rs index af1a069..3a6ad1a 100644 --- a/src/main.rs +++ b/src/main.rs @@ -73,27 +73,36 @@ fn parse_cli() -> (String, bool, Option) { log_level = Some(s.trim_start_matches("--log-level=").to_string()); } "--help" | "-h" => { - eprintln!("Usage: telemt [config.toml] [OPTIONS]"); + eprintln!("telemt - Telegram MTProto Proxy v{}", env!("CARGO_PKG_VERSION")); eprintln!(); - eprintln!("Options:"); - eprintln!(" --silent, -s Suppress info logs"); - eprintln!(" --log-level debug|verbose|normal|silent"); - eprintln!(" --help, -h Show this help"); + eprintln!("USAGE:"); + eprintln!(" telemt [CONFIG] [OPTIONS]"); + eprintln!(" telemt --init [INIT_OPTIONS]"); eprintln!(); - eprintln!("Setup (fire-and-forget):"); - eprintln!( - " --init Generate config, install systemd service, start" - ); + eprintln!("ARGS:"); + eprintln!(" Path to config file (default: config.toml)"); + eprintln!(); + eprintln!("OPTIONS:"); + eprintln!(" -s, --silent Suppress info logs (equivalent to --log-level silent)"); + eprintln!(" --log-level Set log level [possible values: debug, verbose, normal, silent]"); + eprintln!(" -h, --help Show this help message"); + eprintln!(" -V, --version Print version number"); + eprintln!(); + eprintln!("INIT OPTIONS (fire-and-forget setup):"); + eprintln!(" --init Generate config, install systemd service, and start"); eprintln!(" --port Listen port (default: 443)"); - eprintln!( - " --domain TLS domain for masking (default: www.google.com)" - ); - eprintln!( - " --secret 32-char hex secret (auto-generated if omitted)" - ); - eprintln!(" --user Username (default: user)"); + eprintln!(" --domain TLS domain for masking (default: www.google.com)"); + eprintln!(" --secret 32-char hex secret (auto-generated if omitted)"); + eprintln!(" --user Username for proxy access (default: user)"); eprintln!(" --config-dir Config directory (default: /etc/telemt)"); - eprintln!(" --no-start Don't start the service after install"); + eprintln!(" --no-start Create config and service but don't start"); + eprintln!(); + eprintln!("EXAMPLES:"); + eprintln!(" telemt # Run with default config"); + eprintln!(" telemt /etc/telemt/config.toml # Run with specific config"); + eprintln!(" telemt --log-level debug # Run with debug logging"); + eprintln!(" telemt --init # Quick setup with defaults"); + eprintln!(" telemt --init --port 8443 --user admin # Custom setup"); std::process::exit(0); } "--version" | "-V" => {
