How to loris

Read a file, for example a .dat file and loop over all events

import loris
my_file = loris.read_file("/path/to/my-file.dat")
events = my_file['events']

for event in events:
    print("ts:", event.t, "x:", event.x, "y:", event.y, "p:", event.p)

Write events from an array to an .es file

ordering = "xytp"  # corresponds to the order in your array
loris.write_events_to_file(event_array, "/path/to/my-file.es", ordering)

Write structured events (with dtypes) to an .es file

loris.write_events_to_file(structured_event_array, "/path/to/my-file.es")

Windows test (for developers)

To make sure the library works on Windows (if you use macOS or Linux), follow these steps:

1. Download Vagrant (https://www.vagrantup.com/)
2. cd windows
3. vagrant up (this will download a virtual machine and build the package)
4. vargrant ssh (optional, to inspect the Windows VM)
5. vagrant destroy -f (cleanup)
