Writing an Array Variable to a File
Writing an Array Variable to a File
It often occurs that you want to save the value of an array so that you can
analyze its results at a later time. The following macro writes array values to
a file:
proc save_to_file {var fname} {
set values [capture dprint $var]
set f [open $fname w]
}
puts $f $values
close $f
The following example shows how you might use this macro. Using the exec
command tells the shell’s cat command to display the file that was just
written.
d1. dprint list3
list3 = {
(1) = 1 (0x00000001)
(2) = 2 (0x00000002)
(3) = 3 (0x00000003)
}
d1. save_to_file list3 foo
d1. exec cat foo
list3 = {
(1) = 1 (0x00000001)
(2) = 2 (0x00000002)
(3) = 3 (0x00000003)
}
d1.
