Use JerryScript Debugger
Detailed description about the debugger is available here.
To enable the debugger support under IoT.js, the --jerry-debugger option
should be passed to the tools/build.py. The server part of the debugger is
intergrated into the binary of IoT.js.
To start the debugger-server: <iotjs binary> --start-debug-server test.js
It is important to note that optional parameters (such as --debugger-wait-source or
--debugger-port <PORT>) should be specified after --start-debug-server in order to work properly.
The --debugger-wait-source makes the client wait until the source files are sent by the debugger-client.
The file argument is ignored in this case, therefore doesn't need to be specified. IoT.js is also capable of resetting the context,
thus, there's no need to restart the environment if the remote source is changed.
Important note: Remote sources must be sent in correct order! IoT.js compiles them in the order they are received, so file(s) used with require should be sent first, and the file(s) using them after.
If you want to specify the port number of the debugger-server (default: 5001),
you can do so with the --debugger-port <PORT> option:
<iotjs binary> --start-debug-server --debugger-port 8080 test.js
Two clients are included, a python
and an HTML variant, they can be found under deps/jerry/jerry-debugger/.
Note: When snapshot support is enabled, you won't be able to examine js-modules that are loaded from snapshots.
