如何使用多维数组

Question

I have a directory file which contains all the paths for Definition files Test FIlesand Instruction files. Definition file looks like

##Definition file

Def 1 : "definition 1"

Def 2 : "definition 2"

Def 3 : "definition 3"

Each Instruction File contains Instruction sets like

##Instruction File 1
{

Instruction 1

run Def1

sleep

run def2

}
{

Instruction 2

run Def 3

sleep

run Def1

}

likewise multiple instruction files with multiple instruction sets

Test File looks like
{

run Instruction file1 Instruction 2

sleep 5

}

Can anyone guide me how to do this. Like how to run a specific instruction from an Instruction file

Can I use multidimensional array to do it like Storing the Commands, Instruction file and Instruction in a multidimensional array?

Answer 1

You could use hash refs and array references.

The hash could key on the destination and then the array reference could store the array of instructions.

$ref->{'key'} = \\@array

To open a file for reading "<"

open FILE, "<", "filename.txt" or die $!

To get all its lines:

my @lines = <FILE>

From here just split up the code based on your instructions, perhaps using a regex.

foreach my $line (@lines) {
    #do stuff here for the instructions
    #maybe a regex
}

Then iterate through and process each one..

For your test file issue you could store it associatively.

So you'd have an array of test file "command groups"

Each element could store a hash of 3 associated values

$test[0] = { command => $command , filename => $filename, instruction => $instruction };

From here you could access elements such as:

$test[0]->{command}
