View File Error handling for GG API functions template Note: This file is intended to be used by script developers. If you don't develop scripts or don't know what it is, ignore this file. Description: The file consists of three functions: - "attachHandler" function modifies a function in a way that when it returns a string, specified error handling function is called with that string as argument. It returns modified version of the function. This function should only be used on functions that return a string with error description when an error occurs. There is a list of such functions from GG API in the file. - "defaultHandler" function is an example of error handling function. - "testError" function (commented by default) "simulates" a function that has returned a string with error description, used for testing. How to use: 1. Include contents of the file at the beginning of your code. 2. Optionally create custom error handling functions. Error handling function has to accept 1 argument - a string with error description. 3. Use "attachHandler" function to get modified version of the function and either redefine original function with it or store it in a new variable. 4. Repeat step 3 for all desired functions. Examples: -- Custom error handling function local function myHandler(errorText) gg.toast('Whoops, looks like something went wrong', true) gg.toast('Mysterious error: ' .. errorText) print('Description of the error that has occurred during script execution:\n' .. errorText) end -- Using default error handling function and redefining the original function gg.searchNumber = attachHandler(gg.searchNumber, defaultHandler) -- Using custom error handling function and storing modified function in a new variable local getResultsModified = attachHandler(gg.getResults, myHandler) -- If an error occurs, "defaultHandler" function will be called gg.searchNumber('123', gg.TYPE_DWORD) -- If an error occurs, no error handling function will be called local results1 = gg.getResults(100) -- If an error occurs, "myHandler" function will be called local results2 = getResultsModified(100) Submitter CmP Submitted 01/01/2019 Category Templates
