Pull-request selection:
|
|
--repo OWNER/REPOSITORY Limit results to one repository (or use GH_REPO).
|
|
--all[=BOOL] Include every open PR in --repo. Default: %t.
|
|
--limit NUMBER Maximum PRs to load, from 1 to 1000. Default: %d.
|
|
|
|
GitHub and refresh:
|
|
--poll DURATION Base refresh interval, at least 2s. Default: %s.
|
|
--endpoint URL GitHub GraphQL endpoint.
|
|
Default: %s.
|
|
|
|
Appearance and navigation:
|
|
--theme NAME dark, light, catppuccin, catppuccin-latte,
|
|
gruvbox, gruvbox-light, one-dark-pro, github,
|
|
github-light, high-contrast, no-color, or custom.
|
|
Default: %s.
|
|
--dashboard-mode MODE hotkey or intermediate. Default: %s.
|
|
--thread-list-width N List width in percent, from 20 to 60. Default: %d.
|
|
--fold-resolved[=BOOL] Start resolved threads folded. Default: %t.
|
|
--compact-reviews[=BOOL] Aggregate submitted-review history. Default: %t.
|
|
--path-scroll[=BOOL] Scroll truncated file paths. Default: %t.
|
|
--path-scroll-interval D Path scroll step interval. Default: %s.
|
|
--editor-mode MODE vim or standard. Default: %s.
|
|
|
|
Local state:
|
|
--config FILE TOML configuration file.
|
|
Default: %s.
|
|
--cache[=BOOL] Enable instant cached startup and offline fallback.
|
|
Default: %t.
|
|
--cache-max-age DURATION Maximum offline cache age; 0 disables expiry.
|
|
Default: %s.
|
|
--cache-dir DIRECTORY Override the operating-system cache directory.
|
|
|
|
Other:
|
|
-h, --help Show this help and exit.
|
|
|
|
Boolean options accept explicit values, for example --cache=false.
|
|
Command-line options override TOML settings. GH_REPO is used only when
|
|
--repo is absent. DIPLE_CONFIG selects a configuration file; GH_THREADS_CONFIG
|
|
is retained as a migration fallback.
|
|
|
|
Authentication uses GH_TOKEN or GITHUB_TOKEN when set, otherwise the active
|
|
credential from 'gh auth login'. Run 'diple completion --help' for completion
|
|
installation guidance.
