Dave Jarvis commented on FREEMARKER-115:
----------------------------------------
I'm using [FMPP|http://fmpp.sourceforge.net/], so it's possible that FMPP is
being meddlesome with a custom filter action. The only FTL directive that coded
into the *index.html* template is:
{{<#ftl encoding="UTF-8">}}
{{<#assign updated = .now>}}
{{<!doctype html>...}}
The invocation of FMPP is:
{{ fmpp --interpolation-syntax squareBracket -S "$TPL_DIR" \}}
{{ -Q \}}
{{ -D "resource:$RESOURCE_DIR" \}}
{{ -O . "$1"}}
Where TPL_DIR is "$SCRIPT_DIR/template" and SCRIPT_DIR is the directory where
the shell script resides.
I'll see if this is an FMPP bug and report back.

> Key: FREEMARKER-115
> URL: https://issues.apache.org/jira/browse/FREEMARKER-115
> Project: Apache Freemarker
> Issue Type: Bug
> Components: engine
> Affects Versions: 2.3.28
> Reporter: Dave Jarvis
> Priority: Major
>
> Using FMPP with FreeMarker to render a document. The main document resembles:
> {code:java}
> <#assign updated = .now>
> <!doctype html>
> <html lang="en">
> <head>
> <meta charset="utf-8"/>
> </head>
> <body>
> <main>
> <article>
> <#include "includes/html/body.html" parse=false>
> </article>
> </main>
> </body>
> </html>
> {code}
> The file *includes/html/body.html* contains:
> {code:java}
> <div class="code">
> <pre><code>SCRIPT_DIR="\
> $(\
> cd "$(dirname "${BASH_SRC_DIR[0]}")" \
> >/dev/null 2>&1 \
> && pwd\
> )"
> SCRIPT_NAME=$(basename $0)</code></pre>
> </div>
> {code}
> Note the &𝗮𝗺𝗽; &𝗮𝗺𝗽;. When the main document is parsed by FreeMarker, the
> resulting document contains:
> {code:java}
> <div class="code"><pre><code>SCRIPT_DIR="\
> $(\
> cd "$(dirname "${BASH_SRC_DIR[0]}")" \
> >/dev/null 2>&1 \
> && pwd\
> )"
> SCRIPT_NAME=$(basename $0)</code></pre></div>
> {code}
> Note the &𝗮𝗺𝗽; &, which is invalid HTML. The following line from the main
> document does not appear to prevent the engine from meddling with the
> contents, despite *parse=false* being set:
> {code:java}
> <#include "includes/html/body.html" parse=false>
> {code}
> The expected result, of course, is &𝗮𝗺𝗽;&𝗮𝗺𝗽; as per:
> {code:java}
> && pwd\
> {code}
> A larger concern is that FreeMarker produced invalid HTML that wasn't caught
> in a unit test.
