RepRapFirmware - Webserver
|
|
|
|
This class serves web pages to the attached network. These pages form the user's interface with the
|
|
RepRap machine. It interprests returned values from those pages and uses them to Generate G Codes,
|
|
which it sends to the RepRap. It also collects values from the RepRap like temperature and uses
|
|
those to construct the web pages.
|
|
|
|
It implements very very restricted PHP. It can do:
|
|
|
|
<?php print(myStringFunction()); ?>
|
|
<?php if(myBooleanFunction()) print(myOtherStringFunction()); ?>
|
|
<?php if(myOtherBooleanFunction()) echo 'Some arbitrarily long string of HTML including newlines up to this quote:'; ?>
|
|
|
|
Note that by printing a function that returns "" you can just call
|
|
that function in this C++ code with no effect on the loaded web page.
