Lua API moved into a tio library table and names adjusted to Lua stdlib style.
Regex in expect() replaced with Lua patterns so binary data can be handled.
New tio.alwaysecho variable allows enabling and disabling echo to console.
Read and write functions now manage complex retry and timeout logic internally,
giving the user a simple "nil if fail" API like the rest of Lua.
exit() was removed, os.exit() already exists in the Lua standard library.
This commit only effects Linux.
The description field of the `device_list`, populated by
`tty_search_for_serial_devices()`, was either incorrect or less than ideal
for CDC ACM virtual com ports. For instance:
(i) Some devices incorrectly have the description field populated by
the 'product' property of USB hub they are connected via.
(ii) Other devices have description fields populated with the interface,
e.g. CDC, when there is a 'product' property available that would give a
clearer description.
To solve these issues, we first prioritise searching for the 'product' property
of the device over the 'interface' property. We also look for the
'product' property in an additional directory.
This timestamp format will print the seconds since epoch along with
subdivision in microseconds.
Example:
[1748009585.087083] tio v3.9-8-g2fb788f-dirty
[1748009585.087156] Press ctrl-t q to quit
[1748009585.087683] Connected to /dev/ttyUSB0
Git is being dumb about
67c071633d This PR is identical to that one and will supercede it.
Fix --auto new and --auto latest on MacOS.
'device_list' was both a global (eww!) and a local inside
tty_search_for_serial_devices(). The local got set and
returned, so it looked sane, but the caller used the global
instead of the return value of the function it had just
called, meaning (global) device_list was NULL while
(ignored, local) device_list held a perfectly lovely
linked list.
Tested:
tio --auto new waits for a new device to appare and connects
tio --latest will connect to the most recently attached device
which, in most worlds, is the most recently enumerated USB
device, conveniently skipping all the bluetooth nonsense.
If the lone USB device is disconnected, it then connects to
one of those, meaning you really do have to restart tio.
for MacOS
- Added error handling and memory management
- Improved code readability and consistency
- Updated coding style to match project conventions
- Added robust error checking for CoreFoundation property retrieval
- Implemented more defensive memory allocation and type checking
- Switched to using callout device key for more reliable device discovery
- Added single-line block bracing consistent with project style
- Improved comments and code formatting
- Used `kIOCalloutDeviceKey` instead of `kIODialinDeviceKey` for device path retrieval
- Enhanced type checking for CoreFoundation objects
- Simplified memory management and error handling
- Added additional logging and error reporting
- Verified functionality on MacOS 10.11 and 10.15. Tested with ESP32-P4 and ESP32-BOX
Resolves potential device discovery and memory management issues in the MacOS serial device detection code.
