malelabts / regexgenerator Goto Github PK

Hi, it seems your online demo is not available right now.

The goals of the academic paper published were VERY interesting. This got my attention and I thought it was worth looking at.

But there are problems in what is provided.

I do not see any extensive test data and the results of creating regular expressions with that test data here in this GitHub repo. Instead, the only test I saw - DataSetTest.java - is very, very simple. This is not adequate, not even for software produced by an academic institution.

It is not even the case that the test properly illustrates how one would use the software.

So here is the issue:

The kind of software described in the academic paper could be quite useful, but to be evaluated, there should be tests that use various datasets and then show the accuracy of the discovered regular expressions. In addition, those tests should make it clear to an outsider how one would use the software.

If you want your software to be used, you should make it practical to evaluate and adopt.

regex.inginf.units.it has been down now for a couple of days. Will it be coming back?

I am sorry to post this here, but I can't find a repo for the regex golf tool. The thing is that I am trying to find a regex for all ~420 valid (actually used in the language) Mandarin syllables (as in http://pinyin.info/rules/initials_finals.html) and nothing else out of the 22*35=770 possible combinations. This task has historically lead to monster regexes, and I am quite interested in how RG works on it.

By the descriptions the golf tool seemed to be the optimal tool for such a use-case. I can manually construct a "dataset", but that's a bit weird.

Hi!
I need something similar to parse javascript stack strings in different environments and extract the type, message and stack frames (called function, location). Almost every browser has its own stack string format and I can test only a few environments. E.g.:

old Opera:

Statement on line 44: Type mismatch (usually a non-object value used where an object is required)
Backtrace:
  Line 44 of linked script file://localhost/G:/js/stacktrace.js
    this.undef();
  Line 31 of linked script file://localhost/G:/js/stacktrace.js
    ex = ex || this.createException();

V8 (Chrome, Node):

ReferenceError: x is not defined
    at repl:1:5
    at REPLServer.self.eval (repl.js:110:21)
    at repl.js:249:20

It would be nice to write a parser which is adaptive and learns the actual environment on the fly. Can you tell me more about what algorithm you use to generate the regex or how your lib works in general?

edit:
I just read in a different issue that there is no javascript port, because of a missing feature in the js regex lib. Does that mean it is not possible to port this lib at all? If so, is it possible to write something more specific with a different algorithm to solve my problem?

How easy / complex is it to support 'substitutions'?

I use simple example to data set only 5

but it can not generate result

The online version of the RegexGenerator++ prompts the following error when trying to run the example dataset:

The application generates the following error:

But no further error info is provided.

Entering examples on the website (http://regex.inginf.units.it/) went smoothly until my 9th example, 1c==guess_count. Why can't I enter that as a matchless example? I cannot remove the unwanted, automatic match that appears (on the entire string).

(Also, I was not able to submit the above via the website's Feedback button: there was no response to clicking Send.)

I clean and build the projects such as README file said.
I export the dataset from the example in http://regex.inginf.units.it/ and I execute the bash file with the suggested parameters.
Nonetheless when I try to run it I got the following error:

The standard ant command generates the output ConsoleRegexTurtle.jar. regexturtle.sh should point directly to this file.

I am currently doing research to understand the software. The regex generated do not seem to be working when used natively in java. For example, using the available dateset References/Lead-Author, the regex "(?<=\. )[^,]++, (?:\w\.)++" does not work.
Is there something that can be done?

Thanks

Hi team,

I am trying to test the tool with my own sample dataset, but the "Evolve" button is not active. I followed the video tutorial and actually it was working fine a few weeks ago. Would you please double check and fix?

If I click on "Try an example", the button becomes enabled. So, I tried to manipulate the examples and replace the text there with my own text, but I got the following error:

The application generates the following error: Dataset doesn't respect the imposed size limits Ok

Thanks,
Moahemd

I try to run the software (without GUI) as follows:

$ git clone [email protected]:MaLeLabTs/RegexGenerator.git
$ cd RegexGenerator
$ cd "Random Regex Turtle"
$ ant -Dplatforms.JDK_1.7.home $JAVA_HOME jar
$ java -jar ./dist/Random_Regex_Turtle.jar 
Usage: java -jar "Random_Regex_Turtle.jar" configFileName [startGui]

Can you please provide an example config file and input (without using the GUI)?

Is anyone aware of a javascript port of this code?
If not i might take a crack at it.
