Re: [Dev] [GSoC-2015] Proposal2 : Siddhi Editor for WSO2 CEP
Hi Mentors, I have completed the autocompletion feature as per the discussion last time. Please find the implementation at [1] https://github.com/TharinduMunasinge/CEP-Siddhi_Editor and the demo at [2] http://tharindumunasinge.github.io/CEP-Siddhi_Editor/eventprocessor/inner_execution_plan.ui.html . Since the semantic validation feature can not be tested in [2 http://tharindumunasinge.github.io/CEP-Siddhi_Editor/eventprocessor/inner_execution_plan.ui.html] I have attached the patch file at [3 https://drive.google.com/file/d/0Bzsd1YmUyJSbU2I5NVpfRU83dWs/view] as well. . It would be great if you could try out the demo/patch and give me feedback/suggestions to improve the editor . If there are issues with demo please update [4] https://github.com/TharinduMunasinge/CEP-Siddhi_Editor/issues. *Current Features : * - Syntax highlighting - completed - Syntax validation and Error highlighting - completed - Semantic validation and error highlighting- completed ( performance can be improved further by using Binary search kind of algorithm to send server calls) - Context-Aware Auto completion - completed ( scoping rules of an inner stream are yet to be handled) [1] : https://github.com/TharinduMunasinge/CEP-Siddhi_Editor [2] : http://tharindumunasinge.github.io/CEP-Siddhi_Editor/eventprocessor/inner_execution_plan.ui.html [3] : https://drive.google.com/file/d/0Bzsd1YmUyJSbU2I5NVpfRU83dWs/view [4] : https://github.com/TharinduMunasinge/CEP-Siddhi_Editor/issues Thanks, *Th**a**rindu Munasin**ghe.* *Undergraduate ,Department of Computer **S**cience and Engineering* *University of Moratuwa.* *Contact no. +94770460887* On Mon, Aug 3, 2015 at 5:18 PM, Sriskandarajah Suhothayan s...@wso2.com wrote: Sure, we'll have a chat on this next Wednesday Suho On Mon, Aug 3, 2015 at 1:50 PM, Tharindu Munasinghe munasinghethari...@gmail.com wrote: Hi Suho, As per the discussion last time , I have implemented the context aware auto-completion feature with regular expression based approach.

Re: [Dev] [GSoC-2015] Proposal2 : Siddhi Editor for WSO2 CEP
Hi Suho, *Weekly Progress Update* I have been working on syntax and semantic error highlighting mechanism. Client side syntax checking is almost completed and I managed to integrate new editor with CEP 4.0 .Once there are no syntax errors , the query will be submitted to the server side Siddhi compiler for semantic error checking . Since the syntax errors are checked in client side, only the semantic error messages will be getting from the server . But there was an issue in displaying the error messages since some of the semantic error messages do not contain the line numbers. To overcome the issue , I divided the query into top level parser rules ( define_stream, execution_element, ...) and send the code to the server in a constructive manner . So that the line which raise the error message can be identified. suppose the code is similar to this, 1. define stream foo(a int ,b string); //define_stream : at line 1-- A 2. 3. define stream foo(a int ,b int); //define_stream : at line 3 ---B 4. 5. from foo//execution_element : at line 5 C 6. select a 7. insert into bar; If the code has no syntax errors then,it will be submitted to server as follows, A , A+B , A+B+C Since this feature can't be demonstrated in github pages. It would be great if we can meet and verify the progress before sending the PR.

Thanks Srinath! I had a quick discussion with Suho last week. He gave me the initial work flow and priorities of the features listed in the proposal. I am currently testing Antr4,Code-mirror and Ace libraries for the implementation purposes. Built the CEP 4.0 and have been getting familiar with SiddhiQL 3.0. Sure we can meet and discuss further details probably on Next Monday. So that I will be able to come up with something thing to demo the progress. Please let me know the time (or else a possible date in next week) for the meeting . Thanks, On 5 May 2015 at 09:01, Srinath Perera srin...@wso2.com wrote: Tharindu, congratulations on the proposal!
