Utilities ​

These are utility functions that are not directly related to Roll20 systems. They provide easy methods for everything from processing text and numbers to querying the user for input.

k.capitalize

function

Capitalize each word in a string

  • string - string -

    The string to capitalize

  • Returns: stringundefined

Example

js
const capitalized = k.capitalize('a word');

function

Splits a comma delimited string into an array

  • string - string -

    The string to split.

  • Returns: array- The string segments of the comma delimited list.

k.debug

function

Alias for console.log that only triggers when debug mode is enabled or when the sheet's version is 0. Useful for entering test logs that will not pollute the console on the live sheet.

  • msg - any -

    'See k.log

  • force - boolean -

    Pass as a truthy value to force the debug output to be output to the console regardless of debug mode.

  • Returns: voidundefined

k.escape

function

Encodes data in Base64. This is useful for passing roll information to action buttons called from roll buttons.

  • data - string|object|Array.<any> -

    The data that you want to Base64 encode

  • Returns: string- The encoded data

k.extractQueryResult

function

Extracts a roll query result for use in later functions. Must be awaited as per startRoll documentation. Stolen from Oosh's Adventures with Startroll thread.

  • query - string -

    The query should be just the text as the ?{ and } at the start/end of the query are added by the function.

  • Returns: Promise- Resolves to the selected value from the roll query

Example

js
const rollFunction = async function(){
 //Get the result of a choose from list query
 const queryResult = await extractQueryResult('Prompt Text Here|Option 1|Option 2');
 console.log(queryResult);//=> "Option 1" or "Option 2" depending on what the user selects

 //Get free form input from the user
 const freeResult = await extractQueryResult('Prompt Text Here');
 consoel.log(freeResult);// => Whatever the user entered
}
const rollFunction = async function(){
 //Get the result of a choose from list query
 const queryResult = await extractQueryResult('Prompt Text Here|Option 1|Option 2');
 console.log(queryResult);//=> "Option 1" or "Option 2" depending on what the user selects

 //Get free form input from the user
 const freeResult = await extractQueryResult('Prompt Text Here');
 consoel.log(freeResult);// => Whatever the user entered
}

k.log

function

An alias for console.log.

  • msg - any -

    The message can be a straight string, an object, or an array. If it is an object or array, the object will be broken down so that each key is used as a label to output followed by the value of that key. If the value of the key is an object or array, it will be output via console.table.

k.orderSection

console.log(attrName);// => "some-button"

k.pseudoQuery

function

Simulates a query for ensuring that async/await works correctly in the sheetworker environment when doing conditional startRolls. E.g. if you have an if/else and only one of the conditions results in startRoll being called (and thus an await), the sheetworker environment would normally crash. Awaiting this in the condition that does not actually need to call startRoll will keep the environment in sync.

  • value - string|number -

    The value to return. Optional.

  • Returns: Promise- Resolves to the value passed to the function

Example

js
const rollFunction = async function(){
 //Get the result of a choose from list query
 const queryResult = await pseudoQuery('a value');
 console.log(queryResult);//=> "a value"
}
const rollFunction = async function(){
 //Get the result of a choose from list query
 const queryResult = await pseudoQuery('a value');
 console.log(queryResult);//=> "a value"
}

k.registerFuncs

function

Function that registers a function for being called via the funcs object. Returns true if the function was successfully registered, and false if it could not be registered for any reason.

  • funcObj - object -

    Object with keys that are names to register functions under and values that are functions.

  • optionsObj - object -

    Object that contains options to use for this registration.

  • optionsObj.type - Array.<string> -

    Array that contains the types of specialized functions that apply to the functions being registered. Valid types are "opener", "updater", and "default". "default" is always used, and never needs to be passed.

  • Returns: boolean- True if the registration succeeded, false if it failed.

Example

js
//Basic Registration
const myFunc = function({trigger,attributes,sections,casc}){};
k.registerFuncs({myFunc});

//Register a function to run on sheet open

k.registerFuncs({openFunc},{type:['opener']})

//Register a function to run on all events
const allFunc = function({trigger,attributes,sections,casc}){};
k.registerFuncs({allFunc},{type:['all']})
//Basic Registration
const myFunc = function({trigger,attributes,sections,casc}){};
k.registerFuncs({myFunc});

//Register a function to run on sheet open
const openFunc = function({trigger,attributes,sections,casc}){};
k.registerFuncs({openFunc},{type:['opener']})

//Register a function to run on all events
const allFunc = function({trigger,attributes,sections,casc}){};
k.registerFuncs({allFunc},{type:['all']})
