hecate
The Hex Editor From Hell!
Usage:
go get -u github.com/evanmiller/hecate
$GOPATH/bin/hecate file1 [file2 [...]]
Hecate is a hex editor designed for reverse engineering file formats without leaving the comfort of your terminal window. Hecate (pronounced HECK-it) features tabbed browsing, in-place editing, large-file support, full-file searching, and Vim-like controls. Place the cursor over some bytes and choose a mode (t for text, p for a bit pattern, i for an integer, f for a floating point) to see what those bytes represent. Toggle endianness with e and signedness with u. Press enter to edit.
Editing
Pressing enter brings up an edit field for the data under the cursor. Make changes and press enter again to write changes to disk. Pressing esc cancels any changes on the current position, otherwise exits edit mode. Navigating passed the edges of the field moves the cursor. The expected format depends on the cursor mode when entering edit mode.
