etch & scry

Two hex tools in one goforge Polylith workspace (module goforge.dev/etch):

• etch — a full-screen terminal hex editor. Classic offset / hex / ASCII layout, nibble-wise hex editing or direct typing in the ASCII pane, undo, go-to-offset, paging. Overwrite-only: bytes are edited in place and the file size never changes.
• scry — a hex viewer: xxd-style dump with hexyl-style byte-class colors (NUL grey, printable cyan, whitespace green, control magenta, non-ASCII yellow), paged through the same pager logic as rubric.

Both binaries reuse rubric’s components — pager, terminal detection, ANSI painting — across workspaces.

Install

go install goforge.dev/etch/cmd/...@latest   # both etch and scry

Or individually:

go install goforge.dev/etch/cmd/etch@latest
go install goforge.dev/etch/cmd/scry@latest

scry

scry file.bin            # dump whole file, paged, colored on a tty
scry -s 0x40 -n 64 a.out # 64 bytes starting at offset 0x40
scry -w 8 -g 4 file.bin  # 8 bytes per row in groups of 4
cat data | scry          # reads stdin

Flags: -n max bytes, -s skip offset (both accept 0x...), -w bytes per row, -g group size, --color and --paging (auto|always|never).

etch

etch file.bin

Works with lsf

lsf opens binary files with etch (e/enter), views them with scry (v), and shows an inline hex peek in its preview pane (x).
