This is useful if the package is being lazily - loaded, and you wish to conditionally call functions in your - `:init' block that are defined in the package. - -:bind Bind keys, and define autoloads for the bound commands. -:bind* Bind keys, and define autoloads for the bound commands, - *overriding all minor mode bindings*. -:bind-keymap Bind a key prefix to an auto-loaded keymap defined in the - package. This is like `:bind', but for keymaps. -:bind-keymap* Like `:bind-keymap', but overrides all minor mode bindings - -:defer Defer loading of a package -- this is implied when using - `:commands', `:bind', `:bind*', `:mode', `:magic', - `:magic-fallback', or `:interpreter'. This can be an integer, - to force loading after N seconds of idle time, if the package - has not already been loaded. -:after Defer loading of a package until after any of the named - features are loaded. -:demand Prevent deferred loading in all cases. - -:if EXPR Initialize and load only if EXPR evaluates to a non-nil value. -:disabled The package is ignored completely if this keyword is present. -:defines Declare certain variables to silence the byte-compiler. -:functions Declare certain functions to silence the byte-compiler. -:load-path Add to the `load-path' before attempting to load the package. -:diminish Support for diminish.el (if installed). -:delight Support for delight.el (if installed). -:custom Call `customize-set-variable' with each variable definition. -:custom-face Call `customize-set-faces' with each face definition. -:ensure Loads the package using package.el if necessary. -:pin Pin the package to an archive." - (declare (indent 1)) - (unless (memq :disabled args) - (macroexp-progn - (use-package-concat - (when use-package-compute-statistics - `((use-package-statistics-gather :use-package ',name nil))) - (if (eq use-package-verbose 'errors) - (use-package-core name args) - (condition-case-unless-debug err - (use-package-core name args) - (error - (ignore - (display-warning - 'use-package - (format "Failed to parse package %s: %s" - name (error-message-string err)) :error))))) - (when use-package-compute-statistics - `((use-package-statistics-gather :use-package ',name t))))))) - -(put 'use-package 'lisp-indent-function 'defun) - -(provide 'use-package-core) - -;; Local Variables: -;; indent-tabs-mode: nil -;; End: - -;;; use-package-core.el ends here |
