It would be nice if when you clicked on jump instructions (the ones that have the arrows drawn on the left) it would scroll the assembly listing so that the destination was in view.

it is fantastic to join this into IDA

After hover:

Notice the vertical line being drawn that wasn't drawn before coming out of the JMP 0x514b2e instruction.

when I run go install loov.dev/lensm@main.It's failed.

go install loov.dev/lensm@main

Perhaps you should add the directory containing `xkbcommon.pc'
to the PKG_CONFIG_PATH environment variable

Please teach me how to fix it.Thanks.

When trying to open go 1.21 binaries, get a path not found for source files.

Amazing & very helpful tool! Thank you for making & sharing it.

It would be even more helpful if you could select & copy text. I want to copy blocks of assembly into other places for experimentation.

My current workaround is to screenshot the asm with Windows Snipping Tool, then "Text actions" button to OCR the text for select & copy.

I think It would be great to use this tool on the web with webassembly.

Technically the core logic needs:

1. list of symbols (

   lensm/internal/disasm/file.go

   Line 3 in d977133

   // File represents an object file, a module or anything that contains functions.

   )
2. a way to disassemble and get line number for each instruction (https://github.com/loov/lensm/blob/main/internal/disasm/code.go#L1)

Rest of the code should work fine.

For people learning assembly it would be nice to have built in instructions descriptions that would be shown on hover.

lensm does not display the source when building source with go 1.20. lensm works ok when building source with go 1.19.

Thanks for making lensm!

In the tradition of godbolt.org and dogbolt.org, I bought the domain name go-dbolt.org just now when I saw this on Twitter. I'll gladly transfer the domain to you for free in case you want to use it for this project.

It seems that lensm does not support go 1.20 binaries yet.

Also getting some errors when trying to compile my program with go 1.19:
unable to load source from "gofile../Users/rhi/code/table/page.go": open gofile../Users/rhi/code/table/page.go: no such file or directory

Many instructions can be rewritten to be clearer for people, e.g.

MOV (R2), R1 ==> R1 := memory[R2]

ADDQ $1, R1 ==> R1 := R1 + 1

LEAQ 0(R1)(R2*4), R3 ==> R3 := R1 + R2 * 4

FMADDS F0, F2, F1, F2  ==> F2 := F0*F1 + F2

It doesn't need to be comprehensive, however if there was a list of substitutions then people can add new ones as the need arises.

There's a file leak with executables not being closed.
