GenSymIO

Usage

use GenSymIO;

or

import GenSymIO;
const gsLogger = new Logger(logLevel, logChannel)
config const NULL_STRINGS_VALUE = 0: uint(8)
proc deepcopy(x: [?d] ?t) : [d] t throws  where t == int || t == real || t == uint || t == bigint || t == bool
proc array(cmd: string, msgArgs: borrowed MessageArgs, st: borrowed SymTab, type array_dtype, param array_nd: int) : MsgTuple throws  where array_dtype != bigint

  • Creates a pdarray server-side and returns the SymTab name used to

  • retrieve the pdarray from the SymTab.

proc makeArrayFromBytes(ref payload: bytes, shape: ?N*int, type t) : [] t throws
proc arraySegString(cmd: string, msgArgs: borrowed MessageArgs, st: borrowed SymTab, type array_dtype) : MsgTuple throws
proc segmentedCalcOffsets(values: [] uint(8), valuesDom) : [] int throws

  • For creating the Strings/SegString object we can calculate the offsets array on the server

  • by finding the null terminators given the values/bytes array which should have already been

  • converted to uint8

proc tondarray(cmd: string, msgArgs: borrowed MessageArgs, st: borrowed SymTab, type array_dtype, param array_nd: int) : MsgTuple throws  where array_dtype != bigint

  • Outputs the pdarray as a Numpy ndarray in the form of a

  • Chapel Bytes object

proc checkCast(c: string, type toType) : bool

  • Utility proc to test casting a string to a specified type

  • arg c:

    String to cast

  • type c:

    string

  • arg toType:

    the type to cast into

  • type toType:

    type

  • returns:

    bool true if the cast was successful, false otherwise

proc buildReadAllMsgJson(rnames: list((string, ObjType, string)), allowErrors: bool, fileErrorCount: int, fileErrors: list(string), st: borrowed SymTab) : string throws
proc jsonToMap(json: string) : map(string, string) throws

  • Simple JSON parser to allow creating a map(string, string) for properly formatted JSON string.

  • REQUIRES THAT DATA DOES NOT CONTAIN : or “. This will only work on JSON that is not nested.
