This io module contains various platform specific functions for detecting
|
|
|
|
how xrep is being used. e.g., Is stdin being piped into it? Is stdout being
|
|
|
|
redirected to a file? etc... We use this information to tweak various default
|
|
|
|
configuration parameters such as colors and match formatting.
