This is done with the following bash script:
```
#!/usr/bin/env bash
process_line() {
local filename=${1%:}
if [[ $4 =~ \"(.*)\"\; ]]; then
local sha256="${BASH_REMATCH[1]}"
fi
[[ -z $sha256 ]] && return 0
local hash=$(nix hash to-sri --type sha256 $sha256)
echo "Processing: $filename"
echo " $sha256 => $hash"
sed -i "s|cargoSha256 = \"$sha256\"|cargoHash = \"$hash\"|"
$filename
}
# split output by line
grep -r 'cargoSha256 = ' . | while IFS= read -r line; do
# split them further by space
read -r -a parts <<< "$line"
process_line "${parts[@]}"
done

|
|
`async` is a tool to run shell commands in parallel and is designed to be
|
|
able to quickly parallelize shell scripts with minimal changes. It was
|
|
inspired by GNU Parallel, with the main difference being that async
|
|
retains state between commands by running a server in the background.
