Funcshion

Description

Given a Bash script with functions declared, funcshion will create one file per function. Each file contains the full function and is named after the (lowercased) function.

Warnings

Please note this script does make assumptions.

1. Functions can be declared in the below ways with no indentation before it.
   1. function Name() {}
   2. func Name() {}
   3. Name() {}
   4. function Name (){}
      1. Please note the spacing is optional
2. The opening and closing brackets of the function must have no indentation.
   1. The body can be indented as much as you want.

Usage

To utilize the tool just pass the script to awk:

awk -f funcshion.awk script-name.sh

Change the path to where the subdirectory should be generated:

awk -f funcshion.awk -v path=/tmp script-name.sh

Change the name of the generated subdirectory:

awk -f funcshion.awk -v subdir=directoryName script-name.sh

Change both the path and the subdirectory names:

awk -f funcshion.awk -v subdir=directoryName -v path=/tmp script-name.sh

Put the files directly into /tmp without creating a subdirectory:

awk -f funcshion.awk -v path=/tmp -v subdir=/ script-name.sh

Example:

$ cat sample.sh
a() {
    echo "a"
}
b() {
    echo "b"
}
c() {
    echo "c"
}

$ ls sample
ls: cannot access 'sample': No such file or directory

$ awk -f funcshion.awk sample.sh

$ ls sample
a  b  c

$ cat sample/a
a() {
    echo "a"
}

$ cat sample/b
b() {
    echo "b"
}

$ cat sample/c
c() {
    echo "c"
}
