Разбор файла на карту с помощью Elixir; Правильно ли я использую функцию Enum.zip?
Я пытаюсь разобрать текстовый файл [результат запроса откуда-то еще] на карту. Моя проблема в том, что я всегда получаю только три предмета на карте. на карте около 30 элементов, и проверка показывает, что они проанализированы. Насколько я вижу, они выглядят нормально...
У меня есть следующий модуль, определенный в Эликсире:
defmodule Statistics do
def read(path) do
case File.read(path) do
{:ok, body} ->
parse_body body
{:error, reason} ->
IO.puts(~s(could not open file "#{path}"\n))
IO.puts(~s("#{:file.format_error(reason)}"\n))
end
end
def parse_lines(lines, keys) do
Enum.reduce(lines, %{}, fn line, built ->
[name | fields] = String.split(line, "\t")
# IO.inspect(fields)
if Enum.count(keys) == Enum.count(fields) do
line_data = Enum.zip(keys, fields) |> Enum.into(%{})
Map.merge(built, %{name => line_data})
else
built
end
end)
end
def parse_body(body) do
[header | lines] = String.split(body, ~r(\r\n|\r|\n))
keys = tl String.split(header, "\t")
parse_lines(lines, keys)
end
end
У меня также есть текстовый файл со следующим содержимым:
Abandon_agent Abandon_system answered_greater_than_20 answered_less_than_20 answered_less_than_15 answered_less_than_10 answered_less_than_5 date

0 0 0 0 0 0 0 2022-10-30
0 0 0 0 4 21 8 2022-10-31
Несмотря на то, что проверка показывает проанализированные данные, Я всегда получаю только это:
%{
"0" => %{
"Abandon_system" => "0",
"answered_greater_than_20" => "0",
"answered_less_than_10" => "21",
"answered_less_than_15" => "4",
"answered_less_than_20" => "0",
"answered_less_than_5" => "8",
"date" => "2022-10-31"
},
"1" => %{
"Abandon_system" => "0",
"answered_greater_than_20" => "1",
"answered_less_than_10" => "21",
"answered_less_than_15" => "0",
"answered_less_than_20" => "2",
"answered_less_than_5" => "12",
"date" => "2022-10-26"
},
"2" => %{
"Abandon_system" => "0",
"answered_greater_than_20" => "0",
"answered_less_than_10" => "16",
"answered_less_than_15" => "7",
"answered_less_than_20" => "0",
"answered_less_than_5" => "21",
"date" => "2022-10-05"
}
}
Просто для полноты проверка полей [parsed] показывает следующее: [все данные]. Я неправильно использую zip?

Проблема в том, что вы используете первый столбец в качестве ключа к карте. В картах может быть только один из каждого ключа. Поскольку у вас есть только три уникальных значения (0, 1, 2) в первом столбце, только последнее вхождение каждого из них выживает после вашего вызова reduce.
Вот пример, который возвращает пары (ключ, значение) в виде кортежа, где вы можете увидеть повторяющиеся ключи, которые заменяются в вашем коде.
def parse_lines(lines, keys) do
Enum.map(lines, fn line ->
[name | fields] = String.split(line, "\t")
line_data = Enum.zip(keys, fields) |> Enum.into(%{})
{name, line_data}
end)
end
