Sort Symbols by Name or Address

[jgreenbaum]

Is your feature request related to a problem? Please describe.

Often I'm looking for symbols around a particular address. I can search for a particular address, but not sort by address so I can browse symbols surrounding an address.

Describe the solution you'd like

A key to sort by address, or sort by name

Describe alternatives you've considered

top is an example of a text UI that provides flexible sorting, like shift-p to sort by process load, and shift-m to sort by memory usage.

Additional context

Filtering would be nice too, like "only show symbols of type FUNC", or sort by symbol type then name or address.

This should be easy. If you know how you would like this done I can look at prototyping.

Hey, thanks for the issue & idea! I like it ⚡

I think we can add a new key binding (e.g. s) to change the sorting. You can take a look at src/elf/symbols.rs to get an idea of the data structure being used there.

It is wrapped in the Elf struct:

binsider/src/elf/mod.rs

Lines 81 to 100 in 236d19e

	/// ELF wrapper.
	#[derive(Debug)]
	pub struct Elf {
	/// File headers.
	pub file_headers: FileHeaders,
	/// Program headers.
	pub program_headers: ProgramHeaders,
	/// Section headers.
	pub section_headers: SectionHeaders,
	/// Symbols.
	pub symbols: Symbols,
	/// Dynamic symbols.
	pub dynamic_symbols: DynamicSymbols,
	/// Dynamic.
	pub dynamic: Dynamic,
	/// Relocations.
	pub relocations: Relocations,
	/// Notes.
	pub notes: Notes,
	}

And that can be accessed via state.analyzer:

binsider/src/app.rs

Lines 27 to 28 in 236d19e

	/// Elf properties.
	pub elf: Elf,

So we can modify that data to apply the sorting :)

Would you be down to implement it? 🐻
