Definitely use a CSV-parser. I just wanted to keep it simple.
I like your little template-engine, but maybe its not really beginner-friendly (and it doesn’t address the selection of the template by CSV header).
my solution with nimble
def load(csv) do
[header | rows] = NimbleCSV.RFC4180.parse_string(csv, skip_headers: false)
Enum.map(rows, fn row -> sentence(row, header) end)
end
defp sentence([name, email, balance], ["name", "email", "balance"]) do
"#{name}, you owe us #{balance} this month. Please see your statement here #{email}"
end
defp sentence([other, header], ["other", "header"]) do
"#{other}, ... #{header} ..."
end
@mnussbaumer’s solution is better because you don’t need to write code for the templates, could even put them in a json if you want. Just create a map header -> template from which to select the template you need.
