<p>Hi Cyril,</p>
<p><br>
</p>
<p>For the remote execution backend (which is the default) is used,
I believe the truncation of the variable content is hardcoded, and
cannot be changed by the user. But for local/in-process execution
backend, the backend should not truncate the output. So, using the
local execution might be part of the solution. In the API, it
could be something like:</p>
<p> public static void main(String[] args) {<br>
{<br>
JShell j = JShell.builder().build();<br>
for (SnippetEvent evt : j.eval("\"a\".repeat(65536)"))
{<br>
System.err.println("output default execution: " +
evt.value().length());<br>
}<br>
}<br>
{<br>
JShell j =
JShell.builder().executionEngine("local").build();<br>
for (SnippetEvent evt : j.eval("\"a\".repeat(65536)"))
{<br>
System.err.println("output local execution: " +
evt.value().length());<br>
}<br>
}<br>
}<br>
</p>
<p><br>
</p>
<p>which produces:</p>
<p>output default execution: 21844<br>
output local execution: 65538</p>
<p><br>
</p>
<p>For the actual tool, there are feedback mode that define the
truncation limit (inside the "UI" tool), and these can be set. For
example:</p>
<p>$ ./jshell --execution local<br>
| Welcome to JShell -- Version 21-internal<br>
| For an introduction type: /help intro<br>
<br>
jshell> /set mode custom normal -command<br>
| Created new feedback mode: custom<br>
<br>
jshell> /set truncation custom 2147483647 varvalue,expression<br>
<br>
jshell> /set feedback custom<br>
| Feedback mode: custom<br>
<br>
jshell> "a".repeat(65536)<br>
$1 ==> "a... very long output<br>
<br>
</p>
<p><br>
</p>
<p>Please also note there's a related bugreport:</p>

<div>Hey, <br>
I'm a user of jshell, I hope this is the correct mailing
list for my question.<br>
It seems jshell snippets value have a character limit. <br>
<br>
It can be reproduced in a jshell with the following (sorry
for the long strings): <br>
<br>
jshell> "a".repeat(21842);</div>
<div>$1 ==>
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
...
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"</div>
<div><br>
</div>
<div>jshell> "a".repeat(21843);</div>
<div>$2 ==>
"aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
...
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa<br>
<br>
--> notice in the second case the last character is cut.<br>
So the limit seems to be of around 21842 characters. <br>
<br>
This does not look related to the jshell tool, it can also
be reproduced with a jdk.jshell.JShell instance
programmatically. It seems to be happening down in the
ExecutionControl implementation.<br>
<br>
This is an issue for me because I'm using functions that
return html or json that are >>20k characters, so my
results get broken.<br>
<br>
Is there a way to change this limit?<br>
<br>
Have a nice day.<br>
