Use up and down arrow keys to navigate history.
Use left and right arrow keys to move cursor back and forth.
We try mimic the behaviour of GNU readline which we can not use because
we also need to react to key commands.
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
Replaces -x, --hexadecimal option with --intput-mode and --output-mode
so it is possible to select hex or normal mode for both input and output
independently.
To obtain same behaviour as -x, --hexadecimal use the following
configuration:
input-mode = hex
output-mode = hex
Many modern RS-485 serial devices such as the ones from FTDI already
operate in RS-485 mode by default and will work with tio out of the box.
However, there are some RS-232/485 devices which need to be switched
from e.g. RS-232 to RS-485 mode to operate accordingly on the physical
level.
This commit implements the switching mechanism and interface required to
enable RS-485 mode. It only works on Linux and with serial devices which
use device drivers that support the Linux RS-485 control interface.
The RS-485 feature is detailed via the following options:
--rs-485 Enable RS-485 mode
--rs-485-config <config> Set RS-485 configuration
Set the RS-485 configuration using the following key or key value pair
format in the configuration field:
RTS_ON_SEND=value Set logical level (0 or 1) for RTS pin when sending
RTS_AFTER_SEND=value Set logical level (0 or 1) for RTS pin after sending
RTS_DELAY_BEFORE_SEND=value Set RTS delay (ms) before sending
RTS_DELAY_AFTER_SEND=value Set RTS delay (ms) after sending
RX_DURING_TX Receive data even while sending data
If defining more than one key or key value pair, they must be comma
separated.
Example use:
$ tio /dev/ttyUSB0 --rs-485 --rs-r485-config=RTS_DELAY_AFTER_SEND=50,RX_DURING_TX
Add a simple line response feature to make it possible to send e.g. a
command string to your serial device and easily receive and parse a line
response.
This is a convenience feature for simple request/response interaction
based on lines. For more advanced interaction the socket feature should
be used instead.
The line response feature is detailed via the following options:
-r, --response-wait
Wait for line response then quit. A line is considered any string ending
with either CR or NL character. If no line is received tio will quit
after response timeout.
Any tio text is automatically muted when piping a string to tio while in
response mode to make it easy to parse the response.
--response-timeout <ms>
Set timeout [ms] of line response (default: 100).
Example:
Sending a string (SCPI command) to a test instrument (Korad PSU) and
print line response:
$ echo "*IDN?" | tio /dev/ttyACM0 --response-wait
KORAD KD3305P V4.2 SN:32477045
Introduce "bold" color option which only apply bold color formatting to
existing system color.
Also make "bold" the default color option.
Fixes all white issue with black on white tio text.
Clean up so that only the following error related printing functions are
used: tio_error_printf(), tio_error_printf_silent(),
tio_warning_printf().
A session mode switch is introduced for error printing so that it will
print error messages with better formatting depending on in or out of
session.
Rework the color option to support setting ANSI color code values
ranging from 0..255 or "none" for no color or "list" to print a list of
available ANSI colors codes.
Also, disables color when piping.
Allow user to select which ANSI color code to use to colorize the tio
text. To successfully set the color the color code must be in the range
0..255.
If color code is negative tio will print all available ANSI colors.
The default color is changed to bold white to make tio defaults usable
for most users, including color blind users.
