PoC: Redirect program output/input to separate window

[fafok29]

This is pretty much the same as the Log window, but it is implemented via the gdb tty command and pseudo tty, so you don't have to change your code for it to work.

The window name can be changed)

Updated solution to use portable functions.

Also not sure if I found the best place to open ptty

In the case of errors occurring when creating the window, you should not return NULL. Instead, return UILabelCreate(parent, 0, "error message here...", -1);

@aolo2 Since you tried making something similar, can you review this commit?

[fafok29]

Didn't work with UILabelCreate, used UICodeInsertContent

This approach (i.e. create your own pts) makes much more sense than what I did (the reverse, try to get the pts of a real terminal). Can't test right now, but I don't think this handles input, which is what most people want the terminal for.

I think this window would work better as a separate plugin.

Here is the general documentation for making plugins: https://github.com/nakst/gf#plugins

In commit 2746442 I have added the following features:

• You can register custom message for receiving data:

UIMessage ReceiveMessageRegister(void (*callback)(char *input));

It returns the message code you should pass to UIWindowPostMessage. The input buffer is freed automatically. Use this to get your MSG_RECEIVED_STDOUT value.

• You can append to the first command that is sent to GDB:

strcat_s(initialGDBCommand, sizeof(initialGDBCommand) - 1, "...\n")

This is where you should append your setPttyCMD.

• You can set a callback for configuration settings.

void InterfaceWindow.config(const char *key, const char *value);

It will match key-value pairs in the section corresponding to the interface window name. So, key-value pairs in the [STDOUT] section would be passed to this callback.

Once you have made this plugin, I will link to it in the README.md.
