This found tons of errors in rig_debug statements
So this patch cleans up all the files that were producing warnings or errors
This should fix a few segfaults when running with debug turned on
The \chk_vfo command to rigctl_parse() accepts an extended response
prefix but does not act upon it, instead it is held over until the
next command. This seems unnecessary as an extended response prefix
can just as easily be added to the following command if required. By
removing this carried over state the processing of commands can be
greatly simplified as per this commit.
On Debian Buster gcc ((Debian 8.2.0-8) 8.2.0) was throwing the following
warning:
CC rigctl.o
../../hamlib/tests/rigctl.c:125:18: warning: ‘have_rl’ defined but not used [-Wunused-const-variable=]
static const int have_rl = 0;
^~~~~~~
and:
CC rotctl.o
../../hamlib/tests/rotctl.c:113:18: warning: ‘have_rl’ defined but not used [-Wunused-const-variable=]
static const int have_rl = 0;
^~~~~~~
Turns out I didn't have the readline-dev package installed. As the have_rl
variable is wrapped in CPP macros, it indeed is not used when readline is not
available.
This makes the first non-option argument end getopt_long() parsing
stop rather than shuffling non-option arguments to the end. This is
necessary so that rig/rotator command language arguments can start
with a '-' character and also it enables the '-' pseudo command to
switch to reading commands from stdin work correctly.
The change also make checking for the '-', switch to stdin, command
stricter in that it must be where a command is expected and it must be
a word containing exactly a single '-' character.
Overall this allows the following styles of use:
$ rigctl R -
$ rigctl - <<EOF
>R -
>EOF
R -
$ echo "R -" | rigctl -
R -
$ rigctl -m 1 M CW -1
$ rigctl F 434000000 - <<EOF
>M FM 15000
>f m
>EOF
M FM 15000
f 145000000
m FM
15000
$
as well as the command line interpreter operation where no commands
nor '-' are provided:
$ rigctl
Rig command: R -
Rig command: r
Rptr Shift: -
Rig command: f
Frequency: 145000000
Rig command: m
Mode: FM
Passband: 15000
Rig command: F 434000000
Rig command: f
Frequency: 434000000
Rig command: q

As commands from a previous session may not be desired, make reading the
history file at rotctl start and writing to it at rotctl close optional
by use of the -i/--read_history or -I/--save-history options.
Compilation is conditional on having Readline and Readline History
support detected at build system configuration time.
History is stored in '$HOME/.rotctl_history' by default. An alternate
path may be specified by setting the ROTCTL_HIST_DIR environment
variable:
$ ROTCTL_HIST_DIR=~/.rotctl rotctl -iI
will temporarily set the history directory to /home/USER/.rotctl and
create .rotctl_history if it does not exist. If the file cannot be read
or written a warning message will be given on stderr.
Implement first cut at storing and recalling history. At this point
history is retained for the current session only.
History is stored as complete command lines even if values are entered
at separate prompts. Readline allows editing and even deleting recalled
history lines.
Initial implementation of Readline input handling. Only if 'configure'
finds Readline will it be enabled and when enabled it will only be used
by rotctl in interactive mode. Passing rotator commands from the rotctl
command line and rotctld use the original input handling which has not
been modified.
Implemented hash table to temporarily store and sort the rot models by ID
to print the --list by model numbers. Hash is implemented using
uthash.h, see http://uthash.sourceforge.net/
Suppressed rot backend register output by setting rig_debug_level to 0
for list output.
Removed rotlist definition of RPC backend.
Various strncpy operations could result in a port pathname that is not a
NULL terminated string as the allowed string length is the same size as
the buffer per the strncpy manual page. This is corrected by assuring
that the allowed length is FILPATHLEN - 1.
Added:
doc/README.rotorez -- backend to API document
Updated:
Added rot_set_conf support to rotorez.c
Added interactive support for rot_set_conf in rotctl.c
Updated rotctl.1 for changes.
