bugfix: Update PAGER env for Windows compatibility in Terminal

[SmartManoj]

Fixes

PS C:\Users\smart\Desktop\GD\Roo-Code> aws sts get-caller-identity

'cat' is not recognized as an internal or external command,
operable program or batch file.

Important

Fixes Windows compatibility by conditionally setting PAGER environment variable in Terminal.ts and updating tests accordingly.

• Behavior:
  • Update PAGER in Terminal.ts to be empty on Windows (process.platform === "win32") and "cat" otherwise.
  • Fixes issue where cat command was not recognized on Windows.
• Tests:
  • Update TerminalRegistry.test.ts to use a platform-specific PAGER value in tests.
  • Modify test descriptions to reflect platform-specific behavior for PAGER.

This makes sense, we might need to consider using a windows-native pager like more. However the fix seems valid.

@KJ7LNW does this seem good to you?

Gonna merge for now, but happy to follow up

This is to disable pager. Empty string is applicable to Unix too but some applications are not set up properly. aws/aws-cli#4972

That looks great as a simple compatibility fix.

The only thing I would question is whether or not PAGER needs to be set in some way to prevent commands from requiring user input in Windows.

@dosu please look at the diff: is there a Windows equivalent to cat that comes with the system?

[KJ7LNW]

FYI in case some future Windows application needs PAGER set and does not support PAGER="", then PAGER=findstr "^" could be an option.

I do not have the means to test this, but findstr is available in all Windows installations.

However, as @SmartManoj points out, PAGER="" should be sufficient for all applications following spec.

I suggest we leave it as it is for now and follow up if someone else has a problem referencing this PR, this comment is mostly for future reference in case somebody needs it.

Is there any source?

Setting an empty string will delete the env, but maybe in the future, they will fix it. Related changes in .NET

okay well clearly my suggestion did not work ... so leaving it blank is probably the best option unless you come up with something

type is there, but it doesn't work.

Each application has separate flags to disable the pager. The agent should use that till then.
