ASM 4 (Java Library) tutorials?

Question

I have recently been working with the Java library 'ASM', which is for modification of bytecode at runtime, in case people didn't know, and I have not been able to find a single tutorial on ASM 4. Except the official manual for ASM 4, which referenced ASM classes that didn't even exist.

I am wondering if anyone knows of any tutorials for the library, which cover basic to intermediate things, such as inserting some code into a method.

Asking for an "up to date" something is pretty much the definition of too localized. — djechlin, Apr 01 '13 at 21:33
Ah, I reworded it to make more sense now. Thanks for pointing that out — OllieStanley, Apr 01 '13 at 21:53
Have you tried looking for any? http://www.javacodegeeks.com/2012/02/manipulating-java-class-files-with-asm.html — djechlin, Apr 01 '13 at 21:57
That's good for the very basics, but I wish to move on into harder and more useful things, which I'm having trouble finding tutorials for. — OllieStanley, Apr 01 '13 at 22:01

What you want to do seems pretty basic (to me). I'd be very surprised if it was not covered, with an example, in the user guide: https://asm.ow2.io/asm4-guide.pdf

There is lots of other documentation linked here: http://asm.ow2.org/

The ASM mailing list is also quite responsive if you ask: http://mail.ow2.org/wws/info/asm

yep, see page 105 of the linked PDF – Tom Carchrae Apr 01 '13 at 22:52
The PDF has been moved here: https://asm.ow2.io/asm4-guide.pdf AFAIK it is the same PDF as mentioned in the answer, but I can't be sure. – Llew Vallis Jul 28 '18 at 05:31
This link also provides a nice example of ASM: http://www.informit.com/articles/article.aspx?p=2755722&seqNum=7 – Abhishek K Nov 19 '19 at 10:12
