Storing code snippets in eclipse

Question

I recently convert to Eclipse after 20 years of using vi and gvim. One of the things I miss about gvim is that I could cut a bunch of different code snippets into named buffers and paste them as I see fit, doing something like repeating a common idiom. For example, I would have it so that "ap insert

 DatabaseHandle handle = null; try { handle = DatabaseConnectionPool.newHandle(); 

and then "bp will embed

  handle.commit(); } finally { handle.rollback(); DatabaseConnectionPool.returnHandle(handle); } 

And I could repeat them both again and again throughout the day. In an answer to another question, someone mentioned that you can “manage code snippets” in Eclipse, but didn't mention how to do it. So now I ask: how do you manage code snippets in Eclipse?

Answer 1

You might want to save these two snippets into code as described in this tutorial .

And don't forget about the ability to quickly execute any java code snippets in scraps (not quite what you want, but it can come in handy from time to time)

Newtopian adds (in the comments)

In fact, templates become much more powerful by adding variables and tabstops inside, so your example above would be dbHandle ctrl+space . It copies fragments from both parts and places your cursor to the right.

Answer 2

Eclipse also offers something very similar to the template function described by VonC, which is called (you think) fragments. Window> Show View> Snippets.

To add a new category of fragments: right-click in the Snippets window and select "Configure ...". Click Create> New Category. If necessary, enter a category name (for example, "Java"). Click "Apply." Once you’ve selected a category, click Create> New Item. Enter your fragment.

To use a fragment, place the cursor where you want to insert the fragment, then double-click on the fragment in the fragment window.

Answer 3

I recently came across a Snip2Code plugin. He has done this work, and I can quickly collect and search for fragments.

Answer 4

Well, a picture is worth a thousand words, but what about it?

Answer 5

The question is old, but the answere link is older;)

Answer 6

I used snippets in some IDEs such as Dreamweaver and Homesite, the old Coldfusion environment. I also use many fragments in the MySQL Workbench - where I type a lot of SQL, it is very convenient there.

Now I am using the Eclipse Java EE IDE to release web developers of the Indigo Release version and found the snippet panel in Window | Show view | Other ... | General | Snippets , I was able to manipulate it and figure out how to add the code I need, how the fragments and how to use it effectively.

Answer 7

Use Eclipse Snipmatch (part of the Eclipse package for Java developers).

• Works well for Java code snippets, but also works for any other language like HTML, ABABP, PHP, etc.
• You can convert any piece of code from your editor directly into a code template. Select the code that you want to convert to a fragment, the "create fragment" context menu, fill out the form and execute.
• snippets can be shared with Git repositories with members of your team.
