SYNOPSIS
ctable arguments ...
DESCRIPTION
ctable is a companion program for ctioga. It takes the same kind of arguments, except that instead of plotting the data acquired from the data sets, it just writes it on standard output, or perform arbitraty operations on it.ctable was written as a toy program to debug the SciYAG Backend system, but it proved much more powerful than it looks. It can be used to do complex data analysis in a scriptable fashion.
OPTIONS
Ruby code
By default, ctable executes the code
-
@block = proc {|set,data,*a|
puts "# #{set}"
data.each do |x,y|
puts "#{x} #{y}"
end
}
The following options can be used to change this behavior.
- -e, --execute BLOCK
-
Executes the given ruby code for each set,
yielding the set name and its data for each. Use
set
to refer to the set's name,
data
for it's data and
args
for the supplementary arguments you're passing to the script.
- -f, --file FILE
-
The same as the
-e
option except that the code is read from a file rather than on the
command-line.
- -r, --require FILE
-
Has the same effect as Ruby's
-r
option.
- -a, --arg a
-
Provides additionnal arguments to your code. Each
-a arg
option pushes the argument on the top of the
args
array provided to your code.
