How to format file strings to a dot path
-2
I want to make a configuration to store items, however, when I was making the paths to get the values, something wrong happened.
HashMap<String, Text> sections;
private void loadKeys() {
List<String> list = new ArrayList<>();
for (String s : sections.keySet()) {
Text te = sections.get(s);
String changeable = s.substring(0, s.length() - 1);
for (int i = 0; i < te.lines(); i++) {
String line = te.getLine(i);
while (line.startsWith(" ")) {
line = line.substring(2);
}
if (!line.startsWith("-")) {
if (line.endsWith(":")) {
changeable = changeable + "." + line.substring(0, line.length() - 1);
} else {
list.add(changeable + "." + line);
}
}
}
}
for (String s : list) {
System.out.println(s);
}
}
Text.java
public class Text {
private List<String> lines = new ArrayList<>();
public Text(String txt) {
if (txt.contains("n")) {
for (String s : txt.split("n")) {
lines.add(s);
}
} else {
lines.add(txt);
}
}
public int lines() {
return lines.size();
}
public String getLine(int line) {
return lines.get(line);
}
@Override
public String toString() {
String string = "";
for (String s : lines) {
if (string.equals("")) {
string = s;
} else {
string = string + "n" + s;
}
}
return string;
}
}
File:
Test11:
Test12:
Test13: 'test'
Test14: 'test2'
Test15: teste
Test16:
Test17: "test test"
The output I want:
- Test11.Test12.Test13: 'test'
- Test11.Test12.Test14: 'test2'
- Test11.Test15: teste
- Test11.Test16.Test17: "test test"
What I got with the code above:
- Test11.Test12.Test13: 'test'
- Test11.Test12.Test14: 'test2'
- Test11.Test12.Test15: teste
- Test11.Test12.Test16.Test17: "test test"
Test12 is being repeated. Can you help me have what I want? Thanks in advance

It is pretty easy. All you need is just keep current level depth and level name. You can do it via recursion or using queue.
public static Map<String, String> readProperties(Path path) throws IOException {
final class Level {
private final String name;
private final int offs;
public Level(String name, int offs) {
this.name = name;
this.offs = offs;
}
}
Map<String, String> map = new LinkedHashMap<>();
// contains all root items for current one with it's offset, to detecl that current level is sub level or parent
Deque<Level> levels = new LinkedList<>();
Pattern pattern = Pattern.compile("(?<offs>\s*)(?<key>[^:]+)\s*:\s*(?<value>.*)\s*");
Files.lines(path)
.map(pattern::matcher)
.filter(Matcher::matches)
.forEach(matcher -> {
int offs = matcher.group("offs").length();
// remove parent levels until reach the parent of current level
while (!levels.isEmpty() && levels.peekLast().offs >= offs) {
levels.removeLast();
}
String key = matcher.group("key");
String value = matcher.group("value");
if (value.isEmpty())
levels.add(new Level(key, offs));
else
map.put(levels.stream().map(level -> level.name).collect(Collectors.joining(".")) + '.' + key, value);
});
return map;
}
