EM_ASM for embedding short snippets and executing them inline, without declaring a function.EM_ASYNC_JS that's similar to EM_JS, but makes it easier to embed asynchronous JavaScript snippets.EM_JS for embedding JavaScript snippets and binding them as C/C++ functions.emscripten::val for storing and operating on JavaScript values in C++.For asynchronous APIs, you might also need to await promises in your synchronous C/C++ code with Asyncify and read the result once the operation is finished.Įmscripten provides several tools for such interactions: You then need a way to store the values and object instances those APIs return, and a way to pass those stored values to other APIs later. If selecting the current entity from the drop-down, data extensions (if any will also be displayed) in the drop-down list.When working on WebAssembly integration with the web, you need a way to call out to external APIs such as web APIs and third-party libraries. Pressing TAB after the inserted entity or attribute transforms the expression into a string which contains only the name of the entity or attribute depending on the selection(s) made from drop-down(s). Selecting an entity and typing a dot opens a new drop-down containing the attributes of that entity. opens a drop-down list containing existing entities. The $m mechanism has been introduced to enable FintechOS engineers to easily select entities and attributes names, transforming them in strings if necessary. Code snippets for entities and attributes Snippets might be nested, meaning that in a placeholder you can insert another snippet, without deactivating the placeholders of the first snippet. To eliminate the unwanted variants and keep the desired one, navigate placeholders using TAB or SHIFT+TAB and when on top of the placeholder that you want to eliminate, press the delete key. Some snippets may have for some fields’ series of placeholders in a row, like: left inner right Typing when cursor is on top of the placeholders will not remove the placeholder text.Navigating from one placeholder to another is no longer possible using TAB and SHIFT+ TAB.They are no longer highlighted with a background color.When the cursor falls outside the snippet, the placeholders will be deactivated and any text which has not been replaced will remain in the snippet. Make sure to replace the placeholders and click OK to save the source code changes. Additionally, such group of placeholders might have identical texts beneath. The presence of one or more cursors indicate that those placeholders will be filled in simultaneously with the same text. IMPORTANT!Replace all placeholders, otherwise, errors might occur as the code snippet syntax might be broken or the syntax remains unbroken but it is logically incorrect. When the cursor is over a placeholder, starting to type will remove the placeholder text. There might be placeholders without underlying text, visible due to a narrow gray line on that position. Pressing TAB when the cursor is over the last placeholder will move the cursor at the end of the snippet. To navigate from one placeholder to another, press the TAB key or SHIFT+ TAB. If no placeholder is available, the cursor will go to the end of the snippet. Upon snippet insertion, the cursor will be placed on the first placeholder (if any). In the example provided above, the ebs.callAction function snippet, “actionId” and “function body“, although not visible in the text above, might be placeholders. The placeholders are highlighted with a background color. The code snippets might contain hint words, known as placeholders which can be easily selected and changed. In the example provided above, “ebs.“ is inserted in front of the function to reduce further typing. NOTE If you do not place the cursor at end of the snippet path / name (full name) before pressing the TAB key, the snippet name will be breaking syntax. Placing the cursor right at the end of the snippet path/name (full name) and pressing the TAB key, the system will replace the string with: ebs.callAction( actionId, ) The snippets can be organized in menus or drop-downs on multiple levels in structures like hierarchies.Ī snippet name together with its selection path may look like: $s. There might be one or more entries in the list which are not snippets but group names in which case typing a dot after them will open new drop-down menu. opens a drop-down list which offers the possibility to choose a snippet name or another. The sections below describe how to use the two mechanisms. displays code snippets for entities and attributes. Using Monaco Intellisense available via the Monaco Editor, the platform provides two mechanisms for using code snippets in Java Script text boxes, as follows: Code Snippets Support for JavaScript Text Boxes Introduction
