How can I show more of stack string in the empty space?

[rew1nter]

Is there a way to print more instead of [...]

GEF hints you that it's an ascii string, so you can use the normal GDB command x/s $addr

[rew1nter]

yeah that's how I've been doing it. but it is easier to see the full ASCII string printed in UI rather than typing the command every time. Iirc peda prints the full ascii text

[hugsy]

Well this value is hardcoded on purpose because having unterminated strings can get quickly out of hands from a UI and performance perspective .

So I guess, you have 2 options:

• edit GEF_MAX_STRING_LENGTH to a bigger value that you find suitable
• directly read the memory from your own custom context pane using gef.memory.read_cstring($addr, max_length=$whatever_you_want)

Option 1 is faster, but more quick'n dirty.
Option 2 is the more suitable IMO since it's a personal UI preference

[rew1nter]

Ummm could you please make sure changing GEF_MAX_STRING_LENGTH has an effect on your end?
I just changed the value and it seems to have no effect. Still only 50 Ascii chars are being printed

Great catch, this was a bug. @Grazfather fixed it, you should be good to go after pulling the latest version.

[Grazfather]

Seems we hardcode it in def dereference_from around line 8507 to 50 characters. We could parameterize that, and in the meantime you could just bump that.

[Grazfather]

This is fixed on main now.

[rew1nter]

btw setting this variable to a large value like 200 shows no ASCII text whatsoever. It probably breaks the UI. You guys could add a check or comment for the largest possible value, better yet, add an option for maximum length

[Grazfather]

That's maybe why it's hardcoded. While we are hardcoding it, we have no reason to check for this sort of thing.
