Externally loaded browser interpreter for non-native language support
View Patent ↗An interpreter program is described that may be loaded from an external resource when needed by a host. In one implementation, the interpreter program is written in a first language and is capable of interpreting a second language. A program, written in the second language, is provided as data to the interpreter program. The interpreter program may then execute the program.
1. A method performed at a computing device, the method comprising:
loading from an external computing resource, an interpreter program written in a language natively supported by the computing device able to execute a voice browser,
the interpreter program being designed to interpret a second program language that is not natively supported by the voice browser on the computing device;
loading a second program written in the second program language; and
executing the second program, by the voice browser, using the interpreter program.
2. The method of claim 1 , wherein the interpreter program is loaded in response to a statement in a document being parsed.
3. The method of claim 2 further comprising, loading the second program in response to a second statement in the document being processed.
4. The method of claim 1 , wherein loading of the second program additionally includes loading the second program as XML data.
5. The method of claim 4 , wherein the XML data is loaded based on a <data> tag or via an AJAX request.
6. The method of claim 1 , wherein the second language is an XML-based language.
7. The method of claim 1 , wherein the second language is SCXML (State Chart XML).
8. The method of claim 1 , wherein the hest computing device includes an HTML browser or a voice browser.
9. The method of claim 1 , wherein the interpreter program is written in one of JavaScript, JScript, or VBScript.
10. A method comprising:
transmitting an interpreter program to a voice browser executing on a host computing device, the interpreter program being written in a programming language natively supported by the voice browser and designed to interpret a programming language that is not natively supported by the browser;
wherein, the interpreter program is transmitted to the host computing device from another device external to the host computing device.
11. The method of claim 10 , further comprising:
transmitting a second program to the browser as input data to the interpreter program.
12. The method of claim 11 , wherein transmitting the second program is performed in response to a second request from the browser.
13. The method of claim 11 , wherein the input data is XML data.
14. The method of claim 11 , wherein the second program is written in an XML-based language.
15. The method of claim 14 , wherein transmitting the interpreter program and the second program to the browser is performed over a wide area network.
16. The method of claim 10 , wherein transmitting the interpreter program is performed in response to a request from the browser.
17. A method performed by a voice server, the method, comprising:
providing, by the voice server, to a computing device over a network, an interpreter program written in a first language and capable of interpreting a second language;
providing, by the voice server, to the computing device, a program written in the second language, the program being provided as data for the interpreter program; and
executing the program, at the computing device, with the interpreter program.
18. The method of claim 17 , wherein the program written in the second language is provided as XML data.
19. The method of claim 17 , further comprising, providing the interpreter program to the computing device over the network from an external computing resource.
20. The method of claim 17 , wherein the second language is SCXML (State Chart XML).
21. The method of claim 17 , wherein the computing device includes a voice browser.
22. The method of claim 17 , wherein the computing device includes an HTML browser.
23. A computer-readable medium having stored thereon instructions for execution by a computing device, the instructions, which when executed, cause a method to be performed at the computing device, the method comprising:
loading from a voice server, an interpreter program written in a language natively supported by a voice browser on the computing device, in response to a statement in a document being parsed;
the interpreter program being designed to interpret a second program language that is not natively supported by the voice browser on the computing device;
loading from the voice server, a second program written in the second program language at the voice browser;
executing, at the voice browser, the second program using the interpreter program;
wherein the second language is an XML-based language.
24. The method of claim 23 , wherein the computing device includes a voice browser.
25. The method of claim 23 , wherein the computing device includes an HTML browser.
26. A method performed at a computing device to execute an application written in a program language that is not natively supported by a voice browser, the method comprising:
parsing a VXML document by the voice browser;
detecting a statement in the VXML document referencing an interpreter program;
receiving, at the voice browser, an interpreter program which interprets the program language that is not natively supported by the voice browser;
loading a program written in the program language for execution at the voice browser.
27. The method of claim 26 , wherein the interpreter program includes an SCXML interpreter and the program includes SCXML application, which is not natively supported by the voice browser.
28. The method of claim 27 , further comprising, using the SCXML interpreter to natively execute the SXML application at the voice browser.
29. The method of claim 26 , wherein the interpreter program is received over a network from an external source.
30. The method of claim 26 , wherein the program language is an XML-based language.
