|
||||
<a href="https://developer.mozilla.org/en-US/docs/Web/HTML/Element/iframe#attr-sandbox" target="_blank">sandboxing</a>.
|
||||
The documentation is contained in the source of this page, please use
|
||||
the "View Source" function of your browser to view it, or have a look at

|
||||
<!-- First, you have to include the following hidden IFrame, which
|
||||
loads the "Perl runner". This is (currently) necessary because this
|
||||
IFrame needs to re-load itself in order to re-run Perl. This IFrame
|
||||
*must* have the "name='perlrunner'" attribute and must be embedded at
|
||||
the same level as the Perl editor IFrame(s). The frames communicate
|
||||
via the "window.postMessage()" mechanism, which is safe for
|
||||
cross-origin communications and sandboxing. Currently, in order to
|
||||
conserve memory, a single runner serves multiple "clients", that is,
|
||||
the "editor" IFrames below.
|
||||
|
||||
It is also possible to link to perleditor.html directly: if it
|
||||
detects that it is not running in an IFrame, it will load the runner
|
||||
on its own (after a very brief delay).
|
||||
-->
|
||||
|
||||
<iframe name="perlrunner" sandbox="allow-scripts" src="perlrunner.html" style="display:none;"></iframe>
|
||||
|
||||
<p>This is a simple example of running a oneliner:</p>
|
||||
|
||||
<!-- The following is a basic example showing a single input file and
|
||||
Perl oneliner.
|
||||
|
||||
All files are currently always encoded as UTF-8, which is why the
|
||||
"-CSD" switch is used below. This is not strictly necessary when the
|
||||
input files are pure ASCII, but it is important to remember that Perl
|
||||
does *not* default to UTF-8. Reading/writing binary data via the
|
||||
editor and runner is currently *not* supported.
|
||||
|
||||
Standard input/output redirection is currently not supported. It is
|
||||
also currently not supported to supply STDIN directly to the script,
|
||||
the workaround is to use input files, supply the filenames on the
|
||||
command line, and use Perl's magic ARGV operator "<>". Support for
|
||||
redirections may be added in a future version.
|
||||
|
||||
The JavaScript shown below is not strictly necessary, it is also
|
||||
possible to specify a "src='...'" attribute directly in the IFrame
|
||||
tag, for example using the "Copy Frame URL" link shown in the editor.
|
||||
|
||||
Note that implementing an automatic resize of the IFrame to fit its
|
||||
contents is nontrivial when sandboxing is enabled, which is why a
|
||||
fixed height is used below.
|
||||
-->
|
||||
|
||||
<iframe id="perl1" sandbox="allow-scripts" class="perleditor" style="height:20em;"></iframe>
|
||||
<script>
|
||||
document.getElementById('perl1').src =
|
||||
"perleditor.html#" + encodeURIComponent(JSON.stringify( {
|
||||
inputs: [ { fn:"in.txt", text:"Foo\nBar\nQuz" } ],
|
||||
cmdline: "perl -CSD -pe 's/[aeiou]/_/g' in.txt",
|
||||
} ));
|
||||
</script>
|
||||
|
||||
<p>This example includes several files:</p>
|
||||
|
||||
<!-- The following example demonstrates (almost) all of the possible
|
||||
options that can be passed to the editor.
|
||||
|
||||
The "cmdline" supports only very basic quoting constructs.
|
||||
|
||||
You may specify the text of a script via "script", or, alternatively,
|
||||
a "script_url" from which the script is to be fetched - however, be
|
||||
aware that cross-origin restrictions may limit your ability to fetch
|
||||
URLs from other origins. You can specify the script's filename with
|
||||
"script_fn".
|
||||
|
||||
Input files ("inputs") are specified as an array of objects; the
|
||||
properties of the object are similar to the script: filenames are
|
||||
specified with "fn", and the text of the file via "text", or
|
||||
alternatively, you may specify a "url" from which the content is to
|
||||
be fetched.
|
||||
|
||||
The output files ("outputs") are an array of filenames. After the
|
||||
script finishes, the "Perl runner" will attempt to read these files
|
||||
and display them to the user. It is also possible to specify output
|
||||
files with the same name as an input file, for example if Perl's "-i"
|
||||
option was used.
|
||||
|
||||
The current working directory of Perl defaults to the "home"
|
||||
directory in Emscripten's virtual file system, currently
|
||||
"/home/web_user", and all filenames are relative to this directory.
|
||||
You may also specify absolute filenames such as "/tmp/foo.txt".
|
||||
However, note that intermediate directories are currently not
|
||||
automatically created, so if you specify files with nonexistent
|
||||
directories like "/tmp/foo/bar.txt" or the relative "foo/bar.txt",
|
||||
this will not work.
|
||||
|
||||
Additional options: Setting "mergeStdOutErr" to a true value causes
|
||||
STDOUT and STDERR output to be output together, similar to the way
|
||||
they would be on the console.
