store - larger data storage for complex item typesLibrary "store" Object/Property Storage System Semi-Simplified. . It's a helpful toolset while designing UDT's as it remains flexible, this helps in not having to remap an entire script while tinkering. Set an object up, and add as man properties as yyou wish. a property can be one of any pine built in types. so a single object can contain sa, ohlc each with a color, a float, an assigned int and those 4 props each have 3 sub-assigned values. as in demo, the alternating table object has 2 different tables it's a pseudo more complex wa to create our own flexible version of a UDT, but that will not ~break~ on library updates so you can update awa without fear, as this libb will no change saving ou the hassle of creating UDT's that continually change. set(dict, _object, _prop, _item)   Add/Updates item to storage.

MiteTricksLibrary "MiteTricks" Matrix Global Registry. Get, Set, automatic growing, universal get/set, multi-matrix dictionaries, multi-dictionary matrixes.. add slice matrixes of any type, share one common global key registry pull up an item from a category, and item name ie a table of info. same cell needs a color, a size, a string, a value, etc.. all of which can be pulled up with the same group id, and key id. just swap which matrix you pull the value from. this has a side benefit of non-repainting and recalculating when pulling values, changing inputs.. makes for very fast/clean usage.. benefit : floats = value strings = names lines = drawn items table =table of data items for this key colors = color for line/table/fill,label.. all of those can be pulled with "get(_VALUES,_groupIDX,_keyIDX)" where only the values matrix needs be swapped, and the same item/coordinates remains for all the possible matrixes that item appears in. also useful as a dictionary/registry for any given type of item,, and goes very handy with floats/strings/colors/bools with my matrixautotable very helpful when prototyping or doing development work as a shortcut. initRegistry()   Registry inititalizer   Returns: registry of string matrix

Object: object oriented programming made possible! Hash map's in Pinescript?? Absolutely This Library is the first step towards bringing a much needed data structure to the Pine Script community. "Object" allows Pine coders to finally create objects full or unique key:value pairs, which are converted to strings and stored in an array. Data can be stored and accessed using dedicated get and set methods. The workflow is simple, but has a few nuances: 0. Import this library into your project; you can give it whatever alias you'd like (I'll be using obj) 1. Create your first object using the obj.new() method and assign it a variable or "ID". 2. Use the object's ID as the first argument into the obj.set() method, for the key and value there's one extra step required. They must be added as arguments to the appropriate prop_() method. Note: While objects in this library technically only store data as strings, any primitive data type can be converted to a string before being stored, meaning that one object can hold data from multiple types at once. There's a trade off though..Pine Script requires that all exported function parameters have pre-defined types, meaning that as convenient as it would be to have a single method for storing and returning data of every type, it's not currently possible. Instead there are functions to add properties for each individual type, which are then converted to strings automatically (the original type is flagged and stored along with the data). Furthermore, since switch/if statements can only return values of the same type, there must also be "get" methods which correspond with each type. Again, a single "get" method which auto-detects the returned value's type was the goal but it's just not currently possible. Instead each get method is only allowed to return a value of its own type. No worries though, all the "get" methods will throw errors if they can't access the data you're trying to access. In that error message, you'll be informed exactly which "get" method you need to use if you ever lose track of what type of data you should be returning. 3. The second argument for obj.set() method is the obj.prop_() method. You just plug in your key as a string and your value and you're done. Easy as that. Please do not skip this step, properties must be formatted correctly for data to be stored and accessed correctly 4. Obj.get_ (s: string, f: float, b: bool, i: int) methods are even easier, just choose whichever method will return the data type you need, then plug in your ID, and key and that's it. Objects will output data of the same type they were stored as! There's a short example at the end of the script if you'd like to see more! prop_string(string: key, string: value) returns property formatted to string and flagged as string type prop_float(string: key, float: value) returns property formatted to string and flagged as float type prop_bool(string: key, bool: value) returns property formatted to string and flagged as bool type prop_int(string: key, int: value) returns property formatted to string and flagged as int type Support for lines and shapes coming soon! new() returns an empty object set(string : ID, string: property) adds new property to object get_f(string : ID, string: key) returns float values get_s(string : ID, string: key) returns string values get_b(string : ID, string: key) returns boolean values get_i(string : ID, string: key) returns int values More methods like Obj.remove(), Obj.size(), Obj.fromString, Obj.fromArray, Obj.toJSON, Obj.keys, & Obj.values coming very soon!!

Dictionary/Object LibraryThis Library is aimed to mitigate the limitation of Pinescript having only one structured data type which is only arrays. It lacks data types like Dictionaries(in Python) or Object (in JS) that are standard for other languages. Tuples do exist, but it hardly solves any problem. Working only with Arrays could be overwhelming if your codebase is large. I looked for alternatives to arrays but couldn't find any library. So I coded it myself and it's been working good for me. So I wanted to share it with you all. What does it do: ================== If you are familiar with Python or Javascript, this library tries to immimate Object/Dictonary like structure with Key Value Pairs. For Example: object= {name:"John Doe", age: 28 , org: "PineCoders"} And then it also tries to immitate the Array of Objects (I call it Stack) like this: stack= Array({name:"John Doe", age: 28 , org: "PineCoders"}, {name:"Adam Smith", age: 32 , org: "PineCoders"}, {name:"Paragjyoti Deka", age: 25 , org: "PineCoders"}) So there are basically two ideas: Objects and Stacks. But it looks whole different in Pinescript for obvious reasons. Limitation: The major limitation I couldn't overcome was that, for all of the values: both input and return values for properties will be of string type. This is due to the limiation of Pinecsript that there is no way to return a value on a if-else statement dynamically with different data types. And as the input data type must be explicitly defined when exporting the library functions, only string inputs are allowed. Now that doesn't mean you won't be able to use integer, float or boolens, you just need to pass the string value for it using str.tostring() method. And the output for the getter functions will be in strings as well. But I have added some type conversion methods that you could use from this library itself. From String to Float, String To Integer and String to Boolean: these three methods are included in this library. So basically the whole library is based on a manipulatiion of Array of strings under the hood. /////////////// Usage /////////////// Import the library using this statement: import paragjyoti2012/STR_Dict_Lib/4 as DictLib Objects First define an object using this method: for eample: object1= DictLib.init("name=John,age=26,org=") This is similar to object1= {name:"John",age:"26", org:""} in JS or Python Just like we did here in for "org", you can set initital value to "". But remember to pass string values, even for a numerical properties, like here in "age". You can use "age="+str.tostring(age). If you find it tedious, you can always add properties later on using .set() method. So it could also be initiated like this object= DictLib.init("name=John") and later on DictLib.set(object1,"age", str.toString(age)) DictLib.set(object1,"org", "PineCoders") The getter function looks like this age= DictLib.get(object1,"age") name=DictLib.get(object1,"name") The first argument for all methods .get, .set, and .remove is the pointer (name of the object). /////////////////////////// Array Of Objects (Stacks) /////////////////////////// As I mentioned earlier, I call the array of objects as Stack. Here's how to initialize a Stack. stack= DictLib.initStack(object1) The .initStack() method takes an object pointer as argument. It simply converts the array into a string and pushes it into the newly created stack. Rest of all the methods for Stacks, takes the stack pointer as it's first arument. For example: DictLib.pushStack(stack,object2) The second argument here is the object pointer. It adds the object to it's stack. Although it might feel like a two dimentional array, it's actually an one dimentional array with string values. Under the hood, it looks like this //////////////////// Methods //////////////////// For Objects ------------------- init() : Initializes the object. params: (string) e.g returns: The object ( ) example: object1=DictLib.init("name=John,age=26,org=") ................... get() : Returns the value for given property params: (string object_pointer, string property) returns: string example: age= DictLib.get(object1,"age") ....................... set() : Adds a new property or updates an existing property params: (string object_pointer, string property, string value) returns: void example: DictLib.set(object1,"age", str.tostring(29)) ........................ remove() : Removes a property from the object params : (string object_pointer, string property) returns: void example: DictLib.set(object1,"org") ........................ For Array Of Objects (Stacks) ------------------------------- initStack() : Initializes the stack. params: (string object_pointer) e.g returns: The Stack example: stack= DictLib.initStack(object1) ................... pushToStack() : Adds an object at at last index of the stack params: (string stack_pointer, string object_pointer) returns: void example: DictLib.pushToStack(stack,object2) ....................... popFromStack() : Removes the last object from the stack params: (string stack_pointer) returns: void example: DictLib.popFromStack(stack) ....................... insertToStack() : Adds an object at at the given index of the stack params: (string stack_pointer, string object_pointer, int index) returns: void example: DictLib.insertToStack(stack,object3,1) ....................... removeFromStack() : Removes the object from the given index of the stack params: (string stack_pointer, int index) returns: void example: DictLib.removeFromStack(stack,2) ....................... getElement () : Returns the value for given property from an object in the stack (index must be given) params: (string stack_pointer, int index, string property) returns: string example: ageFromObject1= DictLib.getElement(stack,0,"age") ....................... setElement() : Updates an existing property of an object in the stack (index must be given) params: (string stack_pointer, int index, string property, string value) returns: void example: DictLib.setElement(stack,0,"age", str.tostring(32)) ........................ includesElement() : Checks if any object exists in the stack with the given property-value pair params : (string stack_pointer, string property, string value) returns : Boolean example: doesExist= DictLib.includesElement(stack,"org","PineCoders") ........................ searchStack() : Search for a property-value pair in the stack and returns it's index params: (stringp stack_pointer, string property, string value) returns: int (-1 if doesn't exist) example: index= DictLib.searchElement(stack,"org","PineCoders") /////////////////////// Type Conversion Methods /////////////////////// strToFloat() : Converts String value to Float params: (string value) returns: float example: floatVal= DictLib.strToFloat("57.96") ............................. strToInt() : Converts String value to Integer params: (string value) returns: int example: intVal= DictLib.strToFloat("45") ............................. strToBool() : Converts String value to Boolean params: (string value) returns: boolean example: boolVal= DictLib.strToBool("true") ............................. Points to remember ............... 1. Always pass string values as arguments. 2. The return values will be of type string, so convert them before to avoid typecasting conflict. 3. Horses can't vomit. More Informations ==================== Yes, You can store this objects and stacks for persisting through the iterations of a script across successive bars. You just need to set the variable using "var" keyword. Remember this objects and stacks are just arrays, so any methods and properties an array have it pinescript, would be applicable for objects and stacks. It can also be used in security functions without any issues for MTF Analysis. If you have any suggestions or feedback, please comment on the thread, I would surely be happy to help.
