Parse multiline output to array in shellscript - arrays

Question

I tried to fetch all repos from a git user and put them into a array within a shell script. Somehow the array doesn´t recognize the new line as a separator and acts like there´s only one multi line element within the array.
Here´s my sample code:
someUser=Joe
declare -a repos=$(curl -s "https://api.github.com/users/$someUser/repos?page=$PAGE&per_page=100" | grep -e 'git_url*' | cut -d \" -f 4 | cut -d"/" -f5 | cut -d"." -f1)
for repo in $repos; do
echo $repo
// some more stuff
done
The output from the curl and cut looks like that:
RepoA
RepoB
RepoC
[...]
How do I get a new line element treated as a new element within the array? I use the array several times so I need one fixed container with all the repositories.

Answer 1

This is the correct way to iterate over the elements of a Bash array:
for repo in "${repos[#]}"; do
Also, to create an array with the output of a command, you need to wrap the $(...) subshell within (...), like this:
declare -a repos=($(curl -s ...))

Thanks to #janos i fixed the script. The additionsl bracket within the delcare line was the problem. Here is the full code. Maybe somebody would like to copy it.
#!/bin/bash
gitUrl="https://github.com"
gitUser="foobar"
cloneCmd="git clone"
fetchCmd="git fetch"
magenta="\033[35m"
green="\033[32m"
def="\033[0m"
declare -a repos=($(curl -s "https://api.github.com/users/$gitUser/repos?page=$PAGE&per_page=100" | grep -e 'git_url*' | cut -d \" -f 4 | cut -d"/" -f5 | cut -d"." -f1))
# Init clone
echo -e "$magenta Cloning new Repositories $def"
for repo in "${repos[#]}"
do
if [ -d $repo ]; then
echo -e "$green \tRepo $repo already exists $def"
continue
fi
$cloneCmd $gitUrl/$gitUser/$repo
done
echo -e "$green Colning finished $def"
# Update Repos
echo -e "$magenta Updating Repositories $def"
for repo in "${repos[#]}"
do
cd $repo
$fetchCmd
cd ..
done
echo -e "$green Update finished $def"
