I'm new to ruby and Chef. I've been developing cookbooks, committing them, uploading them to the Chef Server then deploying them to a Chef client with a role change followed by a "chef-client" run on the client. This process is slow.
How can I, using an IDE (Eclipse in my case), develop cookbooks and be able to debug (set breakpoints, watch variables etc) and run them without uploading them to the Chef Server and then pulling them back down with a chef-client run?

Chef Server The workstation sends the cookbook to the server using a knife. The nodes communicate with the server using the Chef client. If there are any changes made to the infrastructure code, they must be passed through the Chef Server to apply them to the nodes.
A recipe is basically a collection of resource definitions that will create a step-by-step set of instructions to be executed by the nodes. These resource definitions can be mixed with Ruby code for more flexibility and modularity.
The following examples demonstrate various approaches for using resources in recipes: Some more complex ways to debug issues with a Chef Infra Client run include: Using the chef-shell and the breakpoint resource to add breakpoints to recipes, and to then step through the recipes using the breakpoints
Go to the cookbook directory i.e. test-cookbook and follow the below command. Let’s modify a recipe. Either go to directory i.e cookbooks>test-cookbook>recipes and use the following command .rb extension is mandatory without it recipe will not be created. Write the following code in the text editor and exit using the “ESC-:wq” command
The log resource behaves like any other resource: built into the resource collection during the compile phase, and then run during the execution phase. (To create a log entry that is not built into the resource collection, use Chef::Log instead of the log resource.)
If you already know the basics of Chef and are in a hurry, you can just jump to the "Cookbook Development Process" section. (October 24-28, 2022). Chef uses an internal DSL (domain specific language) in Ruby. This decision has powerful implications.
I was also searching for this kind of tool.
Found this one that shows the shef to do it.

You can use Eclipse as a simple editor for Chef Cookbooks. You won't have any IDE support and debug but some people like me might prefer it anyway.
If you would use a Ruby Editor on Eclipse you might get syntax highlighting for .rb Ruby files but I didn't try this yet.
You can make any folder an Eclipse Project (for example the chef-repo OR a specific cookcook) by adding a .project file with inside:
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>PROJECT_NAME</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
</buildSpec>
<natures>
</natures>
</projectDescription>
Then in Eclipse choose File -> Import -> General -> Existing Projects into Workspace and choose the folder where you added the .project file.

For Eclipse Ruby Development Tools, there is no support for chef cookbooks as of 2015 May 13th, however there is proprietary alternative if you want.
RubyMine 7 IDE supports Chef with Auto complete and definition navigation for standard Chef resources and their attributes. Ruby Mine is based on Intellij IDEA.
Instead of RubyMine, this feature works with Intellij IDEA if you install the Chef integration plugin on top of ruby plugin
