- Introduce new 'process' module exposing a Process class with foreign static methods for accessing command-line arguments. - Implement processSetArguments in main.c to store argc/argv, and processAllArguments in process.c to return them as a Wren list. - Add --help flag support to CLI, printing usage with optional arguments. - Include documentation for Process.arguments and Process.allArguments, plus module index and template updates. - Register process module in modules.c and add Xcode project references for new source files. - Add test scripts for allArguments and arguments, verifying list type, count, and expected values.

^title Process Class
|
|
|
|
The Process class lets you work with operating processes, including the
|
|
currently running one.
|
|
|
|
## Static Methods
|
|
|
|
### **allArguments**
|
|
|
|
The list of command-line arguments that were passed when the Wren process was
|
|
spawned. This includes the Wren executable itself, the path to the file being
|
|
run (if any), and any other options passed to Wren itself.
|
|
|
|
If you run:
|
|
|
|
:::bash
|
|
$ wren file.wren arg
|
|
|
|
This returns:
|
|
|
|
:::wren
|
|
System.print(Process.allArguments) //> ["wren", "file.wren", "arg"]
|
|
|
|
### **arguments**
|
|
|
|
The list of command-line arguments that were passed to your program when the
|
|
Wren process was spawned. This does not include arguments handled by Wren
|
|
itself.
|
|
|
|
If you run:
|
|
|
|
:::bash
|
|
$ wren file.wren arg
|
|
|
|
This returns:
|
|
|
|
:::wren
|
|
System.print(Process.arguments) //> ["arg"]
|
