3 url2script🔗ℹ

The url2script script is special: it allows you to easily fetch single-file quickscripts from anywhere on the internet by providing the url to the raw code. It is actually a little smarter than that because it understands non-raw urls from github gists, gitlab snippets, pastebin and pasterack.

Some single-file scripts can be found on the Racket wiki.

A script previously fetched with url2script can also be easily updated by first opening it via Scrits|Manage|Open script… then clicking on Scripts|url2script|Update current script.

When a script is fetched by url2script, a "url2script-info" submodule is automatically added (unless one already exists) with information about the filename in which the script is to be saved (or has been saved), and the original url of the script. The latter is used for updating the script as described above. The submodule looks like this:

(module url2script-info racket/base
(provide url filename)
(define filename "the-default-filename-to-save-the-script.rkt")
(define url "https://url.of.the/script.rkt"))

If you want to publish a single-file quickscript without making a package, consider adding this submodule so as to provide a default filename (otherwise the user who fetches your script will have to type one themselves, and may be unsure what name to pick).

Also consider adding a permissive license. We recommend a dual license Apache 2.0 / MIT:

;;; Copyright <year> <email or name or entity>
;;; License: [Apache License, Version 2.0](http://www.apache.org/licenses/LICENSE-2.0) or
;;; [MIT license](http://opensource.org/licenses/MIT) at your option.

Scripts fetched by url2script are added to the default script directory. They can be modified as desired (as long as the license permits it)

4 Customizing🔗ℹ

Scripts can be selectively deactivated from the library (Scripts|Manage scripts|Library).

If you change the source code of a script installed from the quickscript-extra package (or from any package containing quickscripts), you will lose all your modifications when the package is updated. To avoid this, you can use Quickscript’s shadow scripts: The shadow script calls the original script without modifying it, and can be modified to your taste without being modified when the original script is updated.

In particular, if you want to change the default label, menu path or keybinding of a script installed from quickscript-extra, go to Scripts|Manage|Library…, select the quickscript-extra directory, then the script you want, and click on Shadow. This opens a new (shadow) script that calls the original script where you can change what you want.

Note that the shadowed script is deactivated so as to avoid duplicate menu entries and keybindings.
