9.1.4 Eval Server Operations

Hemlock handles requests for compilation or evaluation by queuing an operation on the current eval server. Any number of operations may be queued, but each eval server can only service one operation at a time. Information about the progress of operations is displayed in the echo area.

Command: Abort Operations (bound to C-c a) ¶

This command aborts all operations on the current eval server, either queued or in progress. Any operations already in the Aborted state will be flushed.

Command: List Operations (bound to C-c l) ¶

This command lists all operations which have not yet completed. Along with a description of the operation, the state and eval server is displayed. The following states are used:

Unsent

The operation is in local queue in the editor, and hasn’t been sent yet.

Pending

The operation has been sent, but has not yet started execution.

Running

The operation is currently being processed.

Aborted

The operation has been aborted, but the eval server has not yet indicated termination.
