Struct AppConfig 

pub struct AppConfig {
    pub log_dir: Option<PathBuf>,
    pub log_dir_source: LogDirSource,
    pub log_enabled: bool,
    pub prompt_preview_chars: usize,
}

Application-wide configuration resolved from environment variables.

Log directory resolution order:

1. ALC_LOG_DIR env var (explicit override)
2. ~/.algocline/logs (home-based default)
3. $XDG_STATE_HOME/algocline/logs or ~/.local/state/algocline/logs
4. Current working directory (sandbox fallback)
5. None — stderr-only mode (no file logging)

• ALC_LOG_LEVEL: full (default) or off.
• ALC_PROMPT_PREVIEW_CHARS: char count for alc_status(pending_filter="preview") prompt truncation. Falls back to algocline_engine::DEFAULT_PROMPT_PREVIEW_CHARS when unset or unparseable. Setting 0 yields empty previews — if you want no prompt at all, use the "meta" preset instead.

Fields

log_dir: Option<PathBuf>

Resolved log directory, or None if no writable directory is available.

log_dir_source: LogDirSource

log_enabled: bool

prompt_preview_chars: usize

Char count for alc_status prompt_preview truncation.
