Count me in as a plaintive requester for a resizeable text box. I know we can use a script that we edit a file outside of Jenkins, but I'm poking at it in an iterative fashion and having a window large enough to do something more than "Hello World" would be peachy. I use Safari 9.1.1 and Chrome version 53.0.2785.116 (64-bit). Will not try on Firefox because of my personal history of "Why is this taking up so much memory?"

I'll be interested in this enhancement as well

Making the window for editing bigger would be great. If there were a way to open an external editor such as vi, even better.

+1 for this. The textarea is so small it's virtually useless. I have to copy/paste the content of that into an IDE and then back again. Very very user unfriendly the way it is

+1

That tiny box is impossible to work with, even for minor script changes. I'm always copying/pasting to/from a real text editor.

Can we do something about this bug as it makes extremely hard even to view to change one line in the pipeline (not to mention being impossible to see an entire block).

Pull requests would be welcome. I am not aware of anyone who is planning to work on it.

I had the same problem and was able to resolve it by installing jquery-ui plugin. Looks like the resizable window depends on a css supplied by jquery-ui, but this dependency is not specified properly.

Hats off to igorlitmanovich. Installing jquery-ui plugin has brought back the resizable editor with a wider view.

Thank you!

tfennelly care to comment? I do not think the jquery-ui plugin is maintained and intended for use in Jenkins 2.x-style UIs. Unfortunately there is no active maintainer of the UI code in workflow-cps.

jglick as I remember it, jquery-ui used to be provided by core. Maybe that has changed. If it has and we want resizing to work, then is it an option to add a dep between the workflow-cps and jquery-ui plugins?

I guess? I do not really know anything about usage of various JS-related plugins in Jenkins, but I thought that these old plugins were obsoleted by core assets and the new packaging system in 2.0.

Possibly duplicate of JENKINS-37183.

Hi. I made a userscript as a workaround.

Hi vctls - that looks very helpful. How do I use this in Jenkins? Do I put this script in a particular location? 

No, you need a browser extension like greasemonkey or tampermonkey.
There may be a way of overriding the layout through a plugin or something, but I'm new to Jenkins so I don't know.

If you click F12, go to the Console tab and paste the commands below, it will improve a little:

{{ document.querySelector('.container').style.width = '100%';}}
{{ document.querySelector('.container').style.padding = '0';}}
{{ document.querySelector('.col-md-offset-2').style.width = '100%';}}
document.querySelector('.col-md-offset-2').style.margin = '0';

A pull request (tested against major browsers) would be very welcome.

https://github.com/jenkinsci/jenkins/pull/2837 improves the situation a bit, but I rather prefer the proposal from vctls . It would be nice to gave a pull request

Made some enhancements to vctls's solution/hack (thanks!) that allows resizing by restyling a parent container with resize:both and calling aceEditor.resize() at the proper times. Like his solution, you'll need Tampermonkey installed to run this UserScript, and since it uses ResizeObserver, it only works with modern Chrome versions. https://gist.github.com/a2intl/293a76ae3323ec21d7cdceb6f7cd63af 

The replay function is very useful, but with this stupid limitation it's a pain in the neck.

Please fix

stupid limitation

mmeschenmoser Refrain from posting such offensive comment. It's generally undesired, and even more on an opensource project where nobody is paying for the time of others.

The editor div has class ui-resizable, and contains a div with class ui-resizable-handle. So I guess the intent was that it should be resizable? But it is not?

Where would you start looking to fix this issue?

Fixing this text box would really help productivity. Another user here hoping to see this delivered. 

This CSS fixes it. The link to the pipeline syntax can get messy, but better than not having resize.

.ace_editor {
  resize:vertical; overflow:auto !important;
}

Even better: The ui-resizable-handle actually works!

This CSS makes it available (with horrible colors!):

.ui-resizable-handle {
 position: absolute;
 bottom: 0;
 background-color: #1f7313;
 width: 100%;
 height: 10px;
 cursor: row-resize;
 opacity: 0.1;
}
.ui-resizable-handle:hover {
 opacity: 0.6;
}

Tested pull requests would be very welcome!

I have created a PR that upgrades jQuery and fixes the issue based on Christian's comment. It is https://github.com/jenkinsci/workflow-cps-plugin/pull/391 . 

fqueiruga can you please go through issues linked from here or the PR and either assign to yourself, In Review, or just mark as Duplicate?

Sure

The Pipeline editor is now resizable in Pipeline: Groovy plugin version 2.84.
