tomohiro/fluentular:1.11.4 is ok。

It would be nice to report syntax error for regular expressions

Currently, Fluentular provides no notification whatsoever to the user when the user's regular expression has syntax error(s). It would be nice to give a notification like this:

Multiple spaces in the Regular Expression form are replaced with one space in the Configuration section

A RE isn't reflected to the format key in the auto-generated configuration code as it is when a RE has multiple spaces like below.

Here is my regular expression. In my case, there are 2 spaces right after the regular expression for the time parameter. Those characters are omitted to one space in the Configuration section.

^(?<time>\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}.\d{3})Z  (?<log_level>\w+) \[(?<module>\w+)\] (?<message>.*)

e.g: https://fluentular.herokuapp.com/parse?regexp=%5E%28%3F%3Ctime%3E%5Cd%7B4%7D-%5Cd%7B2%7D-%5Cd%7B2%7D+%5Cd%7B2%7D%3A%5Cd%7B2%7D%3A%5Cd%7B2%7D.%5Cd%7B3%7D%29Z++%28%3F%3Clog_level%3E%5Cw%2B%29+%5C%5B%28%3F%3Cmodule%3E%5Cw%2B%29%5C%5D+%28%3F%3Cmessage%3E.*%29&input=2022-12-06+03%3A26%3A14.885Z++info+%5BMyApplication%5D+Starting+logging++-+%28MyApplication.java%3A100%29&time_format=%25Y-%25m-%25d+%25H%3A%25M%3A%25S.%25L

Errors in time format parsing

Hey,
In one of my application i have time in format:
2018-03-01T13:02:03.443149+00:00
This format should be recognized by:
%Y-%m-%dT%H:%M:%S.%6N%z
But in your application i got error:
Error: invalid time format: value = 2018-03-01T13:02:03.443149+00:00, error_class = ArgumentError, error = invalid strptime format - '%Y-%m-%dT%H:%M:%S.%6N%z'

Problem is in %6N part, which is not accepted, without this everything else is ok.

Display a test apache2 log msg to demonstrate the data inspector

I was testing this project (and it's pretty cool! - great job!) but it took me some time to get the right apache2 log message. It might be helpful to show one just so folks can see how it works? Anyway, you can close this issue if you don't think it's necessary, but I'm just thinking about the developer experience.

Without further ado -- I used this string:

127.0.0.1 - frank [10/Oct/2000:13:55:36 -0700] "GET /apache_pb.gif HTTP/1.0" 200 2326 "http://www.example.com/start.html" "Mozilla/4.08 [en] (Win98; I ;Nav)"

Which I found from Apache's HTTP Docs.

I hope this helps :)

Shows "Application Error"

Fluentd v1 format

The Fluentd v1 format requires all backslashes on regexes to be escaped, and that does not work on Fluentular.

your site is show Internal Server Error

your site is show Internal Server Error

Should escape # characters

Any regex with # will actually fail because if it's not escaped. (since everything after # is a comment). You should probably probably auto-escape those as \x23

\n in regular expression is not working

Regular Expression:
{\n "uuid": "(?<uuid>[a-f0-9\-]*)",\n},

Test String:

{
  "uuid": "abcd",
},

The above does not give correct response, while the following Regular Expression works:

{
  "uuid": "(?<uuid>[a-f0-9\-]*)",
},
