CascadeJson.kt
A specific format represent file directory in Json
Provide a function for convert to map or json string in Kotlin
Usage
Download zip file in Release, unzip it, put into ~/.m2/repository/
In your build.gradle.kts
repositories {
...
mavenLocal()
}
dependencies {
...
implementation("cwksc:CascadeJsonKt-jvm:0.0.1")
}
Interface
fromStringToMap(jsonString: String): MutableMap<String, String>
fromStringToJsonString(jsonString: String): String
Example
Input:
{
"file1": "value1",
"file2": "value2",
"dir1": {
"file3": "value3",
"file4": "value4"
},
"dir2": ["dir2-key", {
"file5": "value5",
"file6": "value6",
"dir3" : {
"file7": "value7",
"file8": "value8"
}
}]
}
Convert by fromStringToMap:
mapOf(
"file1" to "value1",
"file2" to "value2",
"dir1/file3" to "value3",
"dir1/file4" to "value4",
"dir2/" to "dir2-key",
"dir2/file5" to "value5",
"dir2/file6" to "value6",
"dir2/dir3/file7" to "value7",
"dir2/dir3/file8" to "value8"
)
Convert by fromStringToJsonString:
{"file1":"value1","file2":"value2","dir1/file3":"value3","dir1/file4":"value4","dir2/":"dir2-key","dir2/file5":"value5","dir2/file6":"value6","dir2/dir3/file7":"value7","dir2/dir3/file8":"value8"}
Implementation
() val layers = mutableListOf
() fun dfs(jsonElement: JsonElement) { when (jsonElement) { is JsonObject -> { jsonElement.forEach { (key, value) -> layers.add(key) dfs(value) layers.removeLast() } } is JsonPrimitive -> { result[layers.joinToString("/")] = jsonElement.content } is JsonArray -> { if (jsonElement.size != 2) { throw IllegalArgumentException("Unexpected JsonArray format") } val (directoryKey, jsonObject) = jsonElement result[layers.joinToString("/") + "/"] = directoryKey.jsonPrimitive.content dfs(jsonObject) } } } dfs(json.jsonObject) return result } fun fromStringToJsonString(jsonString: String): String { return Json.encodeToString(fromStringToMap(jsonString)) }">
fun fromStringToMap(jsonString: String): MutableMap<String, String> { if (jsonString.isEmpty()) throw IllegalArgumentException("jsonString is empty") if (jsonString == "{}") return mutableMapOf() val json = Json.parseToJsonElement(jsonString) if (json !is JsonObject) throw IllegalArgumentException("jsonString is not a JsonObject") val result = mutableMapOf<String, String>() val layers = mutableListOf<String>() fun dfs(jsonElement: JsonElement) { when (jsonElement) { is JsonObject -> { jsonElement.forEach { (key, value) -> layers.add(key) dfs(value) layers.removeLast() } } is JsonPrimitive -> { result[layers.joinToString("/")] = jsonElement.content } is JsonArray -> { if (jsonElement.size != 2) { throw IllegalArgumentException("Unexpected JsonArray format") } val (directoryKey, jsonObject) = jsonElement result[layers.joinToString("/") + "/"] = directoryKey.jsonPrimitive.content dfs(jsonObject) } } } dfs(json.jsonObject) return result } fun fromStringToJsonString(jsonString: String): String { return Json.encodeToString(fromStringToMap(jsonString)) }
