** Description

=req-package= provides dependency management for use-package. This allows to write simple and modular configs. Migration from use-package is simple and syntax is almost same.

** Usage

Load req-package:

+BEGIN_SRC emacs-lisp

(require 'req-package)

(req-package use-package-el-get ;; prepare el-get support for use-package (optional) :force t ;; load package immediately, no dependency resolution :config (add-to-list 'el-get-recipe-path "~/.emacs.d/el-get/el-get/recipes") (el-get 'sync) (use-package-el-get-setup))

+END_SRC

Define required packages with dependencies using =:require=. Use =:force t= if you want to avoid dependency management and load right now. Use =:el-get t= or =:el-get package-name= if you want to install from el-get (Requires =use-package-el-get= package setup like described above).

+BEGIN_SRC emacs-lisp

;; init-dired.el

(req-package dired) ;; this form is optional as it doesn't have any configuration

(req-package dired-single :require dired ;; depends on dired :config (...))

(req-package dired-isearch :require dired ;; depends on dired :config (...))

;; init-lua.el

(req-package lua-mode :config (...))

(req-package flymake-lua :require flymake lua-mode :config (...))

;; init-flymake.el

(req-package flymake :config (...))

(req-package flymake-cursor :require flymake :config (...))

(req-package flymake-custom :require flymake :load-path "/path/to/file/directory" :config (...))

+END_SRC

Solve dependencies, install and load packages in right order:

+BEGIN_SRC emacs-lisp

;; order doesn't matter here (require 'init-dired) (require 'init-lua) (require 'init-flymake) (req-package-finish)

+END_SRC

** Logging

You can use =req-package--log-open-log= to see, what is happening with your configuration. You can choose log level in =req-package= group by =req-package-log-level= custom. These log levels are supported: =fatal=, =error=, =warn=, =info=, =debug=, =trace=.

** Migrate from use-package

Just replace all =(use-package ...)= with =(req-package [:require DEPS] ...)= and add =(req-package-finish)= at the end of your configuration file. There is a =:force= keyword which simulates plain old use-package behavior.

** Note

More complex req-package usage example can be found at https://github.com/edvorg/emacs-configs.

Use =load-dir= package to load all =*.el= files in a dir (e.g =~/.emacs.d/init.d=)

** Contribute

Please, pull-request your changes to =develop= branch. Master is used for automatic release package builds by travis-ci.

** Changelog

*** =v1.3=

- :el-get keyword support moved to separate package [[https://github.com/edvorg/use-package-el-get][use-package-el-get]]

*** =v1.2=

- add :el-get keyword

*** =v1.1=

- due to use-package being mature enough drop providers system.
  please refer to [[https://github.com/edvorg/req-package/issues/52][#52]] for migration instructions.

*** =v1.0=

- once you called =req-package-finish= you are able reload package just by reload =req-package= form
- proper errors handling. see =req-package--log-open-log= for messages
- smart add-hook which invokes function if mode is loaded
- refactor providers system
- no need to use progn in :init and :config sections
- no need to use list literal in :require section
- =:loader= keyword now accepts loaders as keywords or as functions.
  e.g. =:el-get=, =:elpa=, =:built-in=, =:path= and =my-loader-fn=
- =req-package-force= replaced with =:force= keyword

*** =v0.9=

- =:loader= keyword support

*** =v0.8=

- bugfixes

*** =v0.7=

- fixed some issues with packages installation. all packages will be installed at bootstrap time
- custom package providers support by =req-package-providers=
- priority feature for cross provider packages loading. you can choose, what to try first - elpa, el-get, or something else

*** =v0.6=

- =el-get= support

*** =v0.5=

- Major system refactoring.
- Fixed bugs with defered loading.
- Significant performance optimization.
- =max-specpdl-size=, =max-lisp-eval-depth= issues completely solved.
- Flexible =:require= keyword parsing.

*** =v0.4.2=

- Bug fixes.

*** =v0.4.1=

- Various tweaks and bug fixes.

*** =v0.4-all-cycles=

- All cycles of your dependencies will be printed now.
- Also there are more handy log messages and some bug fixes.

*** =v0.3-cycles=

- There are nice error messages about cycled dependencies now.
- Cycles printed in a way: =pkg1 -> [pkg2 -> ...] pkg1=.
- It means there is a cycle around =pkg1=.

*** =v0.2-auto-fetch=

- There is no need of explicit =:ensure= in your code now.
- When you req-package it adds =:ensure= if package is available in your repos.
- Also package deps =:ensure='d automatically too.
- Just write =(req-package pkg1 :require pkg2)= and all you need will be installed.
