Configuration

The core reads ~/.config/rizin/rizinrc while starting. You can add e commands to this file to tune the rizin configuration to your taste.

To prevent rizin from parsing this file at startup, pass it the -N option.

All the configuration of rizin is done with the eval commands. A typical startup configuration file looks like this:

$ cat ~/.rizinrc
e scr.color=1
e dbg.bep   = loader

The configuration can also be changed with -e <config=value> command-line option. This way you can adjust configuration from the command line, keeping the .rizinrc file intact. For example, to start with empty configuration and then adjust scr.color and asm.syntax the following line may be used:

$ rizin -N -e scr.color=1 -e asm.syntax=intel -d /bin/ls

Internally, the configuration is stored in a hash table. The variables are grouped in namespaces: cfg., file., dbg., scr. and so on.

To get a list of all configuration variables just type e in the command line prompt. To limit the output to a selected namespace, pass it with an ending dot to e. For example, e file. will display all variables defined inside the "file" namespace.

To get help about e command type e?:

[0x00000000]> e?
Usage: e[?]   # List/get/set config evaluable vars
| e <key>[=<val|?>] [<key>[=<val|?>] ...]] # Get/Set value of config variable <key>
| el[j*qlJ] [<key>]      # List config variables with their descriptions
| e-                     # Reset config variables
| e! <key>               # Invert the boolean value of config variable <var>
| ec[?]                  # Set color for given key (prompt, offset, ...)
| ee <key>               # Open editor to change the value of config variable <var>
| ed                     # Open editor to change ~/.rizinrc
| er <key>               # Set config variable <var> as read-only
| es [<key>]             # List all config variable spaces or sub-keys/sub-spaces if a <key> is provided
| et <key>               # Show type of given config variable <var>
| env [<varname>[=<varvalue>]] # Get/set environment variables

A simpler alternative to the e command is accessible from the visual mode. Type Ve to enter it, use arrows (up, down, left, right) to navigate the configuration, and q to exit it. The start screen for the visual configuration edit looks like this:

[EvalSpace]

    >  anal
       asm
       scr
       asm
       bin
       cfg
       diff
       dir
       dbg
       cmd
       fs
       hex
       http
       graph
       hud
       scr
       search
       io

For configuration values that can take one of several values, you can use the =? operator to get a list of valid values:

[0x00000000]> e scr.nkey=?
scr.nkey = fun, hit, flag
