PI.LOG - jedimatt42/tipi GitHub Wiki
PI.LOG Special file prefix for debugging log
You can write records to the file "PI.LOG" and the records will be written to the /var/log/tipi/tipi.log file along with other TIPI activity. This can be used to trace your own application without creating real files or using the 4A screen.
TI BASIC example:
10 OPEN #1:"PI.LOG"
20 PRINT #1:"BASIC WAS HERE"
30 CLOSE #1
If using a language that allows it, you can actually skip the open and close operations.
For an even more efficient approach you can use the LOG RawExtension, with the TIPI message protocol.
