Hi,
Is there any information in wiki or documentation that shows migrate history old radare2 names and new rizin. Everyone is used to old r2 names, for example, go to the wiki page https://book.rizin.re/tools/rz-diff/intro.html but it is not indicated anywhere that old name this tool is "radiff2", it is so inconvenient when there are few tutorials on rizin, but I want to perform the same action using the radare2 tutorial.

• Example tutorial: https://rderik.com/blog/using-radare2-to-patch-a-binary/

As result, beginners use r2, or need to come up with alias for package names.

• Example wiki page:

also, if we can convert these to use ghidra rather than jsdec.
jsdec gives wrong disassembly. passing same argument to both the parameters.

https://book.rizin.re/crackmes/ioli/ioli_0x05.html

I wanted to do a math operation when reversing a program, and when I took a look at the book, I saw it used the ?vi instruction:

But inside rizin (rizin 0.6.1 @ linux-x86-64, rizinorg/rizin@d9af48b):

[0x0000115d]> ?vi
ERROR: Command '?vi' does not exist.

I searched in the help (?) and I saw the math commands are now under %:

[0x0000115d]> %vi 0x8048000

[0x0000115d]> %vi 0x8048000+34

I can make a PR and update it if you want, but I am still not sure how to do biwise or's work with this new command.

The current book https://book.rizin.re/plugins/dev-asm.html speaks of a Makefile. There is no Makefile anymore in rizin. Only meson.

I suggest to update the documentation.

Do not use db 0x00000 but db @ 0x000000, etc. Check other commands too

rz-diff tool has been updated in the dev branch of rizin. therefore the dev branch of the book should be updated.

I hoped there will be more activity in mdBook, but it still seems immature:

• rust-lang/mdBook#815
• rust-lang/mdBook#88

We should consider to ditch it in favor of Bookdown which has been used for making professionally-looking books for quite a while. This switch will allow us to have both online and PDF/ePub versions out of the box.

We need a chapter on what Table API is, how to use it, some examples.

see librz/util/table.c for the implementation.

When bin.libs it will load all the libraries from the same folder where the selected bin is located and map them at 0x60000000000 for 64 bit archs, and at 0x60000000 for 32 bit archs.

this feature is described in librz/core/cfile.c

also talking about dir.libs=/path/to/my/folder is also a good idea

The number of users was growing fast, and the author-and main developer-had to switch roles from coder to manager in order to integrate the work of the different developers that were joining the project. Since then project has changed it's name to Rizin and reworked development and governance methodology.

It isnt true, radare2 was forked, not renamed.

The example of loading types from string at Loading Types seems to have wrong quotation marks.

[0x000051c0]> "td struct foo {char* a; int b;}" does nothing for me (using rizin 0.5.0 @ windows-x86-64).
[0x000051c0]> td "struct foo {char* a; int b;}" works (note the quotation mark being moved after td command).

rizin -d /bin/ls
[0x7ff1ef147090]> Vpp

But if you press " it will switch into this:

tell in the book we have to install the c++ package

and to do:

call "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat" x64

Codespell is a tool for fix spelling mistakes in the source code. This can be added in the CI
to check for spelling mistakes in the pull requests.

Please note that you might need to ignore some legitimate words while running it. A rough
sketch of the command would look something like this:
$ codespell --skip *.png --ignore-words-list Gameboy,GameBoy,te,fo,ND,ptd

Link: https://github.com/codespell-project/codespell/
Another place on the web where Codespell is used in the CI: https://github.com/yuxans/haproxy-2.2/blob/5f3eb59aff48fb559f68cbedade1204f9c0a82ed/.github/workflows/codespell.yml

Currently, we have only one channel - master, which is deployed to https://book.rizin.re. I suggest:

• Use the same branching scheme as other Rizin projects - stable and dev
• Deploy stable on https://book.rizin.re/
• Deploy dev on https://book-dev.rizin.re/ or a similar domain
• See .github/workflow/mdbook.yml for branch settings (also update the base)
• Update Rizin release checklist issue template to include the step of tagging the book too (optional?)
• Point Rizin site to two version of the books - stable and dev

See rizinorg/rizin#375

By following Crackme IOLI_0x01, i got the error message after input pdf@main on my MacBookPro.

The version of Rizin is rizin 0.6.3 @ darwin-arm-64, package: 0.6.3 (Homebrew).

I would like create a PR to fix it if this is a typo or outdated.

There is this weird comment at the beginning of this section:

9c2bad8#diff-a6a5c4891f18c495766929e9e415d78005d1e8e683439f36ce5c016f602034bbR5

Why that is there?
