Installation

Known to work with GNU Emacs 25.1 and later. Esup may work with older versions of Emacs, but this is NOT guaranteed. Bug reports for problems related to using Esup with older versions of Emacs will most like not be addressed.

The master of all the material is the Git repository at https://github.com/jschaf/esup .

NOTE: The master branch will always contain the latest unstable version. If you wish to check older versions or formal, tagged release, please switch to the relevant tag.

Using MELPA

Add MELPA or MELPA Stable to the list of repositories to access this mode. MELPA tracks this Git repository and updates relatively soon after each commit or formal release. For more detail on setting up see MELPA Getting Started.

For those who want only formal, tagged releases use MELPA Stable:

(require 'package)
(add-to-list 'package-archives
             '("melpa-stable" . "https://stable.melpa.org/packages/") t)

(package-initialize)

For those who want rolling releases as they happen use MELPA:

(require 'package)
(add-to-list 'package-archives
             '("melpa" . "https://melpa.org/packages/") t)
(package-initialize)

After initializing packaging system you can install Esup using preferred way:

package-list-packages

Use <kbd>M-x package-refresh-contents</kbd> and <kbd>M-x package-list-packages</kbd> to get to the package listing and install esup from there.

Manual

You can install esup manually by adding following to your init file:

(unless (package-installed-p 'esup)
    (package-refresh-contents)
    (package-install 'esup))

Cask

Add following to your Cask file:

(source melpa)

(depends-on "esup")

use-package

Add following to your init file:

(use-package esup
  :ensure t
  ;; To use MELPA Stable use ":pin melpa-stable",
  :pin melpa)

El-Get

Esup is included in the El-Get repository. To install Esup using El-Get:

<kbd>M-x el-get-install RET esup RET</kbd>

Another way is to create a recipe file esup.rcp as follows:

(:name esup
 :website "https://github.com/jschaf/esup"
 :description "Emacs Start Up Profiler"
 :type github
 :pkgname "jschaf/esup")

and add it to a directory present in el-get-recipe-path. Then, use <kbd>M-x el-get-install RET esup</kbd> or add:

(el-get-bundle esup)

to your init file.

Manual Install

Download Esup and place the download directory on your load-path like so:

(add-to-list 'load-path "~/.emacs.d/path/to/esup")

And add either of the two following lines to your initialization file. The first only loads Esup when necessary, the 2nd always during startup of GNU Emacs.

(autoload 'esup "esup" "Emacs Start Up Profiler." nil)
;; OR
(require 'esup)

Usage

To start Esup, run <kbd>M-x esup</kbd>, and watch the magic happen.

Profile a custom file with esup

By default, Esup will profile user-init-file. To profile a custom file, call esup with a prefix argument. That is, <kbd>C-u M-x esup</kbd>.

Developing

Patches are always welcome. To submit a patch, use something like the following workflow.
