Hex Viewer is a plugin for Sublime Text that allows the toggling of a file into a hex viewing mode. Hex Viewer also supports hex editing.

Use Package Control

• Toggling a file into hex view mode
• Search bytes by address
• Customizable highlight of byte and corresponding ASCII representation
• Customizable byte grouping and bytes per line
• Hex inspector to view current selected bytes as different unit types (endianness is configurable.)
• Display total selected number of bytes and addresses of first group of consecutive bytes in status bar
• Hex editing
• Checksumming of files
• Generate a hash from a entered string or selection
• Auto open binary files in Hex Viewer (disabled by default)

There are 10 commands available via the command palette or by key-bindings.

• Hex Viewer: Toggle Hex View
• Hex Viewer: Show Hex Inspector
• Hex Viewer: Toggle Endianness (Big|Little)
• Hex Viewer: Set Bits Per Group
• Hex Viewer: Set Bytes Per Line
• Hex Viewer: Find By Address
• Hex Viewer: Show Hex Edit Panel
• Hex Viewer: Discard All Edits
• Hex Viewer: Export Bin
• Hex Viewer: Get Checksum
• Hex Viewer: Generate Hash

Toggle file in or out of hex view

Show the Hex Inspector panel. The Hex Inspector is a panel which shows the current selected byte as different unit types: byte (8 bit), short(signed 8 bit), word (16 bit), int (signed 16 bit), dword (double word 32 bit), longint (signed 32 bit), float (32 bit floating point), double (floating point 64 bit), and binary (8 bit binary).

Toggle the parsing of bytes to big or little endian when showing unit types in Hex Inspector

Allows selection from the quick panel the grouping of bytes by 8, 16, 32, 64, and 128 bits. This will reload the file with this formatting. All edits will be lost, so export your changes before you do this.

Allows selection form the quick panel the the number of bytes to be shown on a line: 8, 10, 16, 24, 32, 48, 64, 128, 256, 512. If the selected value is not divisible by the "bits per group", the closet number of bytes per line will be used.

Find the byte at the specified address. Input is received through the input panel.

Invoking this command will take the currently selected bytes on a line and display them in an input panel. They can then be modified and submitted to replace the original bytes. Strings can also be used by using the "s:" prefix followed by the equivalent ASCII characters that are to replace the selected bytes.

If at any time you would like to discard all of the changes you have currently made to the hex view, you can invoke this command, and a clean hex view will be reloaded.

This command exports the current hex view to a binary file, and if the option is enabled, it will display the checksum of the newly generated binary file.

By default, it opens up a quick panel with all available hashes that can be used as a checksum. When an algorithm is selected, it is used to retrieve the checksum for the current file in hex view mode.

Shows a quick panel allowing you to select the desired hash, and then shows an input panel that allows you to specify the string to be hashed. A panel is then displayed with your generated hash accoriding to specifications.

Allows you to genrate hashes from your current selection(s). Multiselect regions' content will be combined and evaluated together. If a region contains newlines, they will be hashed as well.

Abort the given action.

Settings are configurable in the hex_viewer.sublime-settings file.

• configure byte highlight color, icon, and style
• configure edit highlight color, icon, and style
• set default bits per group
• set default bytes per line
• custom font and font size
• whether to auto show the Hex Inspector panel on hex view load
• whether Hex Inspector is enabled at all
• hash algorithm to use when checksumming
• whether to checksum on file export automatically
• enable/disable auto open of specified binary files
