mulle-scion

🌱 A modern template engine for Objective C

(written in an oldfashioned way)

This is the command-line tool for the MulleScion library. It also provides the documentation for the project in a self-contained webserver. It can use JSON, Plist, XML files, even multiples and mixes, as a datasource for the template variables.

Usage

Usage:
   mulle-scion [options] [input] [datasource] [output] [arguments]

   The Objective-C Template processor
   See: https://github.com/mulle-kybernetik/MulleScion

Options:
   -v[vv]   : increase verbosity
   -I       : set ':' style search path for {% includes ... %} statements
   -w       : start webserver for dox
   -z       : write compressed archive to outputfile
   -Z       : write compressed keyed archive to outputfile (for IOS)

Input:
   -        : Read template from stdin
   template : a MulleScion template path or URL

Datasource:
   -        : Read data from stdin (only if input is not stdin already)
   args     : use arguments as datasource (see below)
   bundle   : a NSBundle. Its NSPrincipalClass will be the datasource
   plist    : plist files or URLs separated by ':' merged into a datasource
   none     : empty datasource

Output:
   -        : Write result to stdout
   file     : Write result to file

Arguments:
   key=value: key/value pairs to be used as __ARGV__ contents
              (unless args as datasource was specified)

Examples:
   echo '***{{ VALUE }}***' | mulle-scion - args - VALUE="VfL Bochum 1848"
   echo '***{{ __ARGV__[ 0]}}***' | mulle-scion - none - "VfL Bochum 1848"

Example

Create informational text from a typical package.json file with the following template:

package.txt.scion:

This is the {{ name }} project version {{ version }}, which resides
on {{ repository.url }}.

{% if dependencies %}
It has the following dependencies:
{% for dep in dependencies %}
{{ dep }} at {{ dependencies[ dep] }}
{% endfor %}
{% endif %}

and the mulle-scion package.json, somewhat trimmed for readability:

package.json:

{
   "name" : "mulle-scion",
   "version" : "1859.1.9",
   "description" : "🌱 A modern template engine for Objective C",
   "homepage" : "https://github.com/MulleWeb/mulle-scion",
   "dependencies" : {
      "Foundation" : "git://github.com/MulleFoundation/Foundation",
      "MulleFoundation" : "git://github.com/MulleFoundation/MulleFoundation",
      "MulleWebServer" : "git://github.com/MulleWeb/MulleWebServer",
      "MulleCivetWeb" : "git://github.com/MulleWeb/MulleCivetWeb"
   }
}
