As discussed in /_posts/2017-01-03-pdp-11-tutorials.md, when a page (usually part of a tutorial)
|
|
wants to create a control that tests some feature of a machine, the page will define a machine command
|
|
using a Liquid-style include that looks like this:
|
|
|
|
{% include machine-command.html type='button' label='Try It!' machine='vt100' component='Keyboard' command='sendString' value='Hello World' %}
|
|
|
|
and which should generate something like this:
|
|
|
|
<button type="button" onclick="commandMachine('vt100','Keyboard','sendString','Hello World')">Try It!</button>
|
|
|
|
Alternatively, if the command parameter is the name of a command string in the page's Front Matter, then this:
|
|
|
|
{% include machine-command.html type='button' label='Try It!' machine='vt100' component='Keyboard' command='scriptName' %}
|
|
|
|
should generate something like this:
|
|
|
|
<button type="button" onclick="commandMachine('vt100','Keyboard','script','...')">Try It!</button>
|
|
|
|

{% if page.commands[include.command] != nil %}{% assign machine_command = "script" %}{% capture command_value %}{{ page.commands[include.command] | replace:'"','"' | strip }}{% endcapture %}{% else %}{% capture machine_command %}{{ include.command }}{% endcapture %}{% capture command_value %}{{ include.value | replace:'"','"' }}{% endcapture %}{% endif %}{% if include.type == "button" %}<button type="button" onclick="commandMachine('{{ include.machine }}','{{ include.component }}','{{ machine_command }}','{{ command_value }}')">{{ include.label }}</button>{% else %}<!-- Unrecognized machine control type: {{ include.type }} -->{% endif %}
