Paradox
|
||||
=======
|
||||
|
||||
Project for modernizing Emacs' Package Menu. With package ratings,
|
||||
usage statistics, customizability, and more.
|
||||
|
||||
Here are some visual comparisons:
|
||||
|
||||
#### Regular Package Menu ####
|
||||
|
||||
|
||||
#### Paradox ####
|
||||
|
||||
|
||||
#### Paradox (multi-line) ####
|
||||
|
||||
*These screenshots use smart-mode-line, but a similar effect is obtained with the regular mode-line.*
|
||||
|
||||
Usage
|
||||
===
|
||||
|
||||
Paradox can be installed from Melpa with `M-x package-install RET
|
||||
paradox`.
|
||||
It can also be installed manually in the usual way, just be mindful of
|
||||
the dependencies.
|
||||
|
||||
To use it, simply call `M-x paradox-list-packages` (instead of the
|
||||
regular `list-packages`).
|
||||
This will give you most features out of the box. If you want to be
|
||||
able to star packages as well, just configure the
|
||||
`paradox-github-token` variable then call `paradox-list-packages`
|
||||
again.
|
||||
|
||||
If you'd like to stop using Paradox, you may call `paradox-disable`
|
||||
and go back to using the regular `list-packages`.
|
||||
|
||||
## Current Features ##
|
||||
|
||||
### Several Improvements ###
|
||||
|
||||
Paradox implements many small improvements to the package menu
|
||||
itself. They all work out of the box and are completely customizable!
|
||||
*(Also, hit `h` to see all keys.)*
|
||||
|
||||
* Visit the package's homepage with `v` (or just use the provided buttons).
|
||||
* View a list of recent commits with `l`.
|
||||
* Use `paradox-require` instead of `require` to automatically install
|
||||
absent packages.
|
||||
* Shortcuts for package filtering:
|
||||
* `f r` filters by regexp (`occur`);
|
||||
* `f u` display only packages with upgrades;
|
||||
* `f k` filters by keyword (emacs 24.4 only).
|
||||
|
||||
And some more...
|
||||
* `hl-line-mode` enabled by default.
|
||||
* Display useful information on the mode-line and cleanup a bunch of
|
||||
useless stuff.
|
||||
* **Customization!** Just call `M-x paradox-customize` to see what you can
|
||||
do.
|
||||
* Customize column widths.
|
||||
* Customize faces (`paradox-star-face`,
|
||||
`paradox-status-face-alist` and `paradox-archive-face`).
|
||||
* Customize local variables.
|
||||
|
||||
|
||||
### Package Ratings ###
|
||||
|
||||
Paradox also integrates with
|
||||
**GitHub Stars**, which works as **rough** package rating system.
|
||||
That is, Paradox package menu will:
|
||||
|
||||
1. Display the number of GitHub Stars each package has (assuming it's
|
||||
in a github repo, of course);
|
||||
2. Possibly automatically star packages you install, and unstar
|
||||
packages you delete (you will be asked the first time whether you
|
||||
want this);
|
||||
3. Let you star and unstar packages by hitting the `s` key;
|
||||
4. Let you star all packages you have installed with `M-x paradox-star-all-installed-packages`.
|
||||
|
||||
Item **1.** will work out of the box, the other items obviously
|
||||
require a github account (Paradox will help you generate a token the
|
||||
first time you call `paradox-list-packages`).
|
||||
|
||||
## Known Bugs ##
|
||||
|
||||
* On some cases there's an annoying gnutls error message after downloading the star counts `gnutls.c: [0] (Emacs) fatal error: The TLS connection was non-properly terminated.`.
|
||||
If anyone knows how to fix it, I'm all ears.
|
||||
|
||||
## How Star Displaying Works ##
|
||||
|
||||
We generate a map of `Package Name -> Repository` from
|
||||
[Melpa](https://github.com/milkypostman/melpa.git)'s `recipe`
|
||||
directory, some repos may correspond to more than one package.
|
||||
This map is used count the stars a given package has.
|
||||
_This doesn't mean you need Melpa to see the star counts, the numbers
|
||||
will be displayed regardless of what archives you use._
|
||||
|
||||
Currently, packages that are not hosted on GitHub are listed with a
|
||||
blank star count, which is clearly different from 0-star packages
|
||||
(which are displayed with a 0, obviously).
|
||||
If you know of an alternative that could be used for these packages,
|
||||
[open an issue](https://github.com/Bruce-Connor/paradox/issues/new)
|
||||
here, I'd love to hear.
