consult-project-extra defines an endpoint for accessing different sources related to the common project workflow. Using Consult’s narrowing system, the user is able to access the current project’s buffers, project files and all the known projects, in case they want to change projects quickly. consult-project-extra provides an extension to the default Consult functionality, using the built-in package project.el, defining the functions consult-project-extra-find and consult-project-extra-find-other-window. Furthermore, consult-project-extra only depends on consult, resulting in a lean and simple to maintain functionality.

⚠️ NOTE: This package has come to life adapting the great package consult-projectile by OlMon. Most if not all credit should go to him, I have been using his package for months now. What inspired me to create this package is my recent effort to avoid most third party packages, specially if they prefer a newly defined interface over the built-in Emacs interface.

As stated in the Emacs manual:

28.2 Working with Projects ==========================

A “project” is a collection of files used for producing one or more programs. Files that belong to a project are typically stored in a hierarchy of directories; the top-level directory of the hierarchy is known as the “project root”.

Whether a given directory is a root of some project is determined by the project-specific infrastructure, known as “project back-end”. Emacs currently supports two such back-ends: VC (*note Version Control::), whereby a VCS repository is considered a project; and EDE (*note EDE::). This is expected to be extended in the future to support additional types of projects.

Which files do or don’t belong to a project is also determined by the project back-end. For example, the VC back-end doesn’t consider “ignored” files (*note VC Ignore::) to be part of the project.

project.el contains generic infrastructure for dealing with projects, some utility functions, and commands using that infrastructure. The goal is to make it easier for Lisp programs to operate on the current project, without having to know which package handles detection of that project type, parsing its configuration files, etc. Throughout the years, project.el has defined utility functions, extending the project detection API. Some examples (from the functions that I use the most) are the functions:

• project-shell-command: run a shell command in the project’s root directory.
• project-async-shell-command: run an async shell command in the project’s root directory.
• project-compile: run the project’s compile command from the project’s root directory.
• project-dired: spawn a dired buffer on the project’s root directory.
• project-kill-buffers: kill all active project buffers.

On the other side, the project management standard package is called Projectile. From its documentation: Its goal is to provide a nice set of features operating on a project level without introducing external dependencies (when feasible). For instance - finding project files has a portable implementation written in pure Emacs Lisp without the use of GNU find (but for performance sake an indexing mechanism backed by external commands exists as well).

For my needs, project.el is more than enough, plus it has the advantage to be included in Emacs since the 27.1 version. It is also key to note that project.el’s API is experimental, and is subject to change in the future. If that’s the case, I’ll be more than happy to revisit this package and fix the hypothetical problems.

Install directly from source (a.k.a this repository) using straight.el. The configuration shown here relies on the use-package macro, which is a convenient tool to manage package configurations.

;; Install from source directly.

(use-package consult-project-extra
  :straight (consult-project-extra :type git :host github :repo "Qkessler/consult-project-extra")
  :bind
  (("C-c p f" . consult-project-extra-find)
   ("C-c p o" . consult-project-extra-find-other-window)))

;; or install from melpa

(use-package consult-project-extra
  :straight t
  :bind
  (("C-c p f" . consult-project-extra-find)
   ("C-c p o" . consult-project-extra-find-other-window)))

Install with the built-in package-install (though I recommend investing in learning use-package or straight above.

;; Make sure you have MELPA as a package source.
(package-refresh-contents)

(package-install 'consult-project-extra)
(require 'consult-project-extra)

Or install using use-package

(use-package consult-project-extra
  :ensure t)

If you want emacs to load the file when it starts, download the consult-project-extra.el file and copy it to the dir “~/.emacs.d/lisp/”, (create that directory if it doesn’t exist) then put the following in your Emacs configuration file:

;; Tell emacs where is your personal elisp lib dir
(add-to-list 'load-path "~/.emacs.d/lisp/")

;; Require consult-project-extra.
(require 'consult-project-extra)
