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.
+ Add missing timestamp-format epoch
+ Update send_ to use fsync and tcdrain like normal tty_sync does
+ Rework read_line to save partial line at timeout
+ Simplified read_line to reduce cyclomatic complexity
+ renamed example files read.lua and read_line.lua
+ moved #define READ_LINE_SIZE to top of file
+ renamed g_linebuf to linebuf, and moved it into read_line as a static variable
After including the use of glib we might as well replace inih
with the glib key file parser.
All configuraiton file parsing has been reworked and also the options
parsing has been cleaned up, resulting in better and stricter
configuration file and option value checks.
Compared to old, configuration files now requires any default
configurations to be put in a group/section named [default].
Configuration file keywords such as "enable", "disable", "on",
"off", "yes", "no", "0", "1" have been retired. Now only "true" and
"false" apply to boolean configuration options. This is done to simplify
things and avoid any confusion.
The pattern option feature has been reworked so now the user can now
access the full match string and any matching subexpression using the
%mN syntax.
For example:
[usb devices]
pattern = usb([0-9]*)
device = /dev/ttyUSB%m1
Then when using tio:
$ tio usb12
%m0 = 'usb12' // Full match string
%m1 = 12 // First match subexpression
Which results in device = /dev/ttyUSB12
Collapses lua high(), low(), toggle(), config_high(), config_low(),
config_apply() into one simple function:
set{<line>=<state>, ...}
Line can be any of DTR, RTS, CTS, DSR, CD, RI.
State is high, low, or toggle.
Example:
script = set{DTR=high, RTS=low}; msleep(100); set{DTR=low, RTS=high}; msleep(100); set{RTS=low}
Notice the use of {} instad of () when calling the set function. This is
required to pass parameters by name in lua.
* Rename --list-devices to --list
* Rename --no-autoconnect to --no-reconnect
* Switch -l and -L options
* -l now lists available serial devices
* -L enables log to file
* Add option --auto-connect <strategy>
* Supported strategies:
* "new" - Waits to connect first new appearing serial device
* "latest" - Connects to latest registered serial device
* "direct" - Connect directly to specified serial device (default)
* Add options to exclude serial devices from auto connect strategy by
pattern
* Supported exclude options:
* --exclude-devices <pattern>
Example: '--exclude-devices "/dev/ttyUSB2,/dev/ttyS?"'
* --exclude-drivers <pattern>
Example: '--exclude-drivers "cdc_acm"'
* --exclude-tids <pattern>
Example: '--exclude-tids "yW07,bCC2"'
* Patterns support '*' and '?'
* Connect to same port/device combination via unique topology ID (TID)
* Topology ID is a 4 digit base62 encoded hash of a device topology
string coming from the Linux kernel. This means that whenever you
plug in the same e.g. USB serial port device to the same USB hub
port connected via the exact same hub topology all the way to your
computer, you will get the same unique TID.
* Useful for stable reconnections when serial device has no serial
device by ID
* For now, only tested on Linux.
* Reworked and improved listing of serial devices to show serial devices:
* By device
* Including TID, uptime, driver, and description.
* Sorted by uptime (newest device listed last)
* By unique topology ID
* By ID
* By path
* Add script interface 'list = tty_search()' for searching for serial
devices.
