Therefore, 20 | first install that program via your preferred method. For example, to install 21 | via the system `gem` command, use: 22 | 23 | sudo gem install asciidoctor 24 | 25 | * Download a zipped {url-releases}[binary] of this plug-in. Unzip and move 26 | `AsciiDoc.qlgenerator` into `/Library/QuickLook`. Note the plug-in will not 27 | work if installed to a user directory `~/Library/QuickLook` due to restraints 28 | imposed by the sand-boxing of Quick Look plug-ins. 29 | 30 | * Lastly, open Terminal and run the command `qlmanage -r` to reset the Quick 31 | Look Server. 32 | 33 | == Customization 34 | 35 | The preview of an AsciiDoc file is generated by converting it to HTML via 36 | Asciidoctor and displaying the resultant HTML. This process can be customized 37 | by setting a preference to override the converter: 38 | 39 | defaults write ca.bluemist2.AsciiDocQuickLook AsciiDocConverter /path/to/my_converter 40 | 41 | The last part of the above command must give the full path to an executable 42 | that accepts one argument, the name of the AsciiDoc file to be previewed, and 43 | writes the corresponding HTML format on standard output. For example, create 44 | a shell script called `asciidoc_to_html` with content similar to the following: 45 | 46 | #!/bin/bash 47 | export PATH=/usr/local/bin:$PATH 48 | asciidoctor -b html5 -a nofooter -a icons=font -o - "$1" 49 | 50 | Ensure the script is executable (use `chmod +x asciidoc_to_html`) and place it 51 | in your `~/bin` folder (create the folder if it does not exist). Lastly, set 52 | the converter preference: 53 | 54 | defaults write ca.bluemist2.AsciiDocQuickLook AsciiDocConverter ~/bin/asciidoc_to_html 55 | 56 | == To Do 57 | 58 | * A process should support sudden termination for the best user experience; 59 | see {url-terminating-processes}[Terminating Processes]. This plug-in works by 60 | launching an Asciidoctor process. Could the handling of this process be 61 | improved? 62 | 63 | * Consider using {url-asciidoctorjs}[asciidoctor.js] to generate previews. 64 | Examine {url-qlswift}[QLSwift] to see how it generates previews using 65 | JavaScript. This method would not require the Asciidoctor program to be 66 | installed (though it would require distribution of `asciidoctor.js`) and it 67 | would not need to launch a separate process. 68 | 69 | == Release History 70 | 71 | * 1.0 (2017-11-06): Initial release 72 | 73 | == License 74 | 75 | Copyright (C) 2017 Clyde Clements 76 | 77 | The AsciiDoc Quick Look plug-in is distributed under the MIT license.
