Command style

The command style of HyperDbg
For ease of use, HyperDbg uses the same command-style as Windbg, which means there are different kinds of commands in HyperDbg.
‌In HyperDbg we have 3 types of commands , "regular", "meta", "extension".
Regular commands, e.g., "test", apply to the debugging session. These are the ones controlling and getting information from the debugging target.
Meta commands are prefixed with a dot, e.g., ".test". Meta commands apply to the debugger itself, meaning that these commands are the ones controlling the debugger itself, not the debugging target.
Extension commands are prefixed with an exclamation mark, e.g. "!test", which is defined in debugger extensions and features.
‌Here is a full example of a command with a detailed description of each field used in documentation.

Command Parameters

HyperDbg uses a static approach for naming the parameter in the debugger help command and the documentation. Here's a brief of how to interpret each field.
Imagine we have the following parameter:
[pid ProcessId (hex)] (optional)
Each word which lower case should strictly come after the command. Each word with the capital case is the parameter's name in which its type is also mentioned between two parentheses.
If the (optional) word is mentioned after the parameter, it is optional, and you can omit it.
!test pid 1240
Another example,
[default]
As you can see, the default is started with lower case, so we should use the command with the default keyword.
!test default
