A collection of Facebook Chisel commands.
Mejsel contains commands for visualizing CGRects and CGPoints, and for
printing information about the current method when stopped in a method preamble. The following sections explain the commands briefly; for more information, use the help <command_name> command in lldb.
| Command | Description |
|---|---|
vrect <rect> <refview> |
Visualizes (using a red-bordered view) a CGRect whose coordinates are specified in the coordinate space of refview. |
vpoint <point> <refview> |
Similar to vrectbut takes a CGPoint as the first parameter instead of a CGRect. |
Note: The arguments passed to the above commands are required to be wrapped in quotes if they contain whitespace. If you don't wrap them, you'll probably be presented with a bunch of lldb error messages.
The following commands only work as expected when stopped in a method preamble, e.g. a Framework method that you don't have the symbols for.
| Command | Description |
|---|---|
parg [--all] [<index>] [<type>] |
Prints method arguments. Tries to guess the argument type based on the method signature. Note: Does not work very well for structs. |
pself |
Prints the value of self. |
psel |
Prints the value of the sel argument, i.e. the selector for the current method. |
These commands haven't been used for very long which means that there are a lot of situations in which they don't work. If you happen to find a certain incantation of a command that always results in errors, please report an issue and I'll have a look.
