    EWC stands for \"Everywhere Window Create\". EWC is a cross-platform implementation of the \u2395WC family of system functions (\u2395WC, \u2395WS, \u2395WG, \u2395WN, \u2395NQ and \u2395DQ) that are available in Dyalog APL for Microsoft Windows.

    EWC only supports a subset of the functionality provided by \u2395WC. This subset is growing, driven by the requirements of early adopters. The supported subset is documented in the object reference.

    Note

    At this time, EWC is work in progress, and not supported via normal channels. A supported release of EWC is expected in mid-2025.

    EWC can run in \"Desktop\" mode using an HTMLRenderer. In this mode, EWC supports multiple forms in the same way as \u2395WC, creating one HTMLRenderer for each form.

    Alternatively, EWC can be initialised in \"Browser\" mode, in which case it starts a listener on the configured port (22322 by default), and a Browser must be connected to that port. In this mode, it really only makes sense to have a single form, although modeal MsgBox's can be popped up if required.

    Finally, there is an experimental \"Multi\" mode, intended to support multi-user applications. In this mode, EWC must also be used via browsers. For each connection, the application namespace is cloned. If the application namespace is called demo, then clones will be named demo_1, demo_2 etc. This allows each session to have separate state.

    The browser-based modes can be used on any Dyalog-supported platform, desktop mode is restricted to the platforms where the HTMLRenderer is available - currently Linux, MacOS and Windows.

    "},{"location":"#getting-started","title":"Getting Started","text":"

    Check out the installation instructions, the section on initialisation, or the implementation details.

    If you are not familiar with \u2395WC, you may want to start with the standard Dyalog documentation for this feature. The documentation for EWC only discusses differences between the original Win32 based implementation (\u2395WC) and the emulation (EWC).

    Note

    During prototyping, the project has been known as JSWC, or \"JavaScript WC\". Both the code and the documentation for EWC still contain references to JSWC. Until the transition is complete, JSWC should be read as EWC anywhere that it occurs.

    "},{"location":"Discussion/Differences/","title":"EWC versus \u2395WC","text":"

    Most importantly, EWC only supports a subset of the objects supported by \u2395WC - and for each of the supported classes, only a subset of the features of the class.

    If you use an unsupported property, EWC will output a warning message to the log and continue, in the hope that your application will work in a degraded mode. The warning message identifies the line of application code that used the unsupported feature. For example:

    59:15.169 W: *** Warning: at Make[16] wMakeSubForm[8] - Unsupported on button: FCol BCol Accelerator

    You can decide to ignore the warning, work around it, or request support for the missing feature from Dyalog. For more information, see the documentation of supported classes.

    "},{"location":"Discussion/Differences/#validation-and-error-messages","title":"Validation and Error Messages","text":"

    Property validation and error messages are not as reliable as \u2395WC and \u2395WS. If you provide incorrect property values, the results can be unpredictable: the property may simply be ignored, in the worst case the form will be blanked out due to the creation of invalid HTML.

    In EWC all images are defined using images files, which can be in any format supported by web browsers. You can not refer directly to image files on your local machine, the images must be served up by the web server whic his embedded in EWC.

    The location of your images must be declared by setting the variable EWC.RESOURCES before calling EWC.Init, for example:

    EWC.RESOURCES\u21901 2\u2374'images' '/tmp/myapp/images'

    This creates a virtual folder /images/ that can be referred to when using images.

    The ImageList object has a new property Files, which contains a list of the file names that define the ImageList. It is not possible to populate an ImageList by creating child icons and bitmap objects, as in \u2395WC.

    The File property of an Icon, and the Picture property of a Button, Form and several other properties, are also affected by this.

    If you are developing EWC, or you are working with EWC developers and need to quickly pick up changes to the JavaScript client, it may be a good idea to clone the client code separately. In order for EWC to automatically find this code, it must be located in a folder called ewc-client, in the same folder as EWC itself.

    EWC stands for \"Everywhere Window Create\". EWC is a cross-platform implementation of the \u2395WC family of system functions (\u2395WC, \u2395WS, \u2395WG, \u2395WN, \u2395NQ and \u2395DQ) that are available in Dyalog APL for Microsoft Windows.

    EWC only supports a subset of the functionality provided by \u2395WC. This subset is growing, driven by the requirements of early adopters. The supported subset is documented in the object reference.

    Note

    At this time, EWC is work in progress, and not supported via normal channels. A supported release of EWC is expected in mid-2025.

    EWC can run in \"Desktop\" mode using an HTMLRenderer. In this mode, EWC supports multiple forms in the same way as \u2395WC, creating one HTMLRenderer for each form.

    Alternatively, EWC can be initialised in \"Browser\" mode, in which case it starts a listener on the configured port (22322 by default), and a Browser must be connected to that port. In this mode, it really only makes sense to have a single form, although modeal MsgBox's can be popped up if required.

    Finally, there is an experimental \"Multi\" mode, intended to support multi-user applications. In this mode, EWC must also be used via browsers. For each connection, the application namespace is cloned. If the application namespace is called demo, then clones will be named demo_1, demo_2 etc. This allows each session to have separate state.

    The browser-based modes can be used on any Dyalog-supported platform, desktop mode is restricted to the platforms where the HTMLRenderer is available - currently Linux, MacOS and Windows.

    "},{"location":"#getting-started","title":"Getting Started","text":"

    Check out the installation instructions, the section on initialisation, or the implementation details.

    If you are not familiar with \u2395WC, you may want to start with the standard Dyalog documentation for this feature. The documentation for EWC only discusses differences between the original Win32 based implementation (\u2395WC) and the emulation (EWC).

    Note

    During prototyping, the project has been known as JSWC, or \"JavaScript WC\". Both the code and the documentation for EWC still contain references to JSWC. Until the transition is complete, JSWC should be read as EWC anywhere that it occurs.

    "},{"location":"Discussion/Differences/","title":"EWC versus \u2395WC","text":"

    Most importantly, EWC only supports a subset of the objects supported by \u2395WC - and for each of the supported classes, only a subset of the features of the class.

    If you use an unsupported property, EWC will output a warning message to the log and continue, in the hope that your application will work in a degraded mode. The warning message identifies the line of application code that used the unsupported feature. For example:

    59:15.169 W: *** Warning: at Make[16] wMakeSubForm[8] - Unsupported on button: FCol BCol Accelerator

    You can decide to ignore the warning, work around it, or request support for the missing feature from Dyalog. For more information, see the documentation of supported classes.

    "},{"location":"Discussion/Differences/#validation-and-error-messages","title":"Validation and Error Messages","text":"

    Property validation and error messages are not as reliable as \u2395WC and \u2395WS. If you provide incorrect property values, the results can be unpredictable: the property may simply be ignored, in the worst case the form will be blanked out due to the creation of invalid HTML.

    In EWC all images are defined using images files, which can be in any format supported by web browsers. You can not refer directly to image files on your local machine, the images must be served up by the web server whic his embedded in EWC.

    The location of your images must be declared by setting the variable EWC.RESOURCES before calling EWC.Init, for example:

    EWC.RESOURCES\u21901 2\u2374'images' '/tmp/myapp/images'

    This creates a virtual folder /images/ that can be referred to when using images.

    The ImageList object has a new property Files, which contains a list of the file names that define the ImageList. It is not possible to populate an ImageList by creating child icons and bitmap objects, as in \u2395WC.

    The File property of an Icon, and the Picture property of a Button, Form and several other properties, are also affected by this.
