regex's Introduction

ReGeX is a Android game that's all about "Regular Expressions". In different modes the user can try to solve tasks, which range from having to match only certain strings but not others, or extracting parts of a string with a regular expression, making it enjoyable (under a certain definition of pleasure) for beginners and people with more experience alike.

More information can be found on the project homepage, the app can be downloaded from F-Droid, and most of the development (including issues and suggestions) is to be found on GitHub. ReGeX is published under GPLv3.

regex's Issues

No solution displayed

It would be useful to provide a "Solution" button for beginners to learn the game.

Highest level

What is the highest achievable level? I've been at 13 for the longest time and though it was the highest, then I just did one puzzle today (after a long pause) and I suddenly got LVL 14.

Explain regex chars and their functions ingame

The game lacks explanation. People that hope to learn regex via this game will be disappointed.

An ingame explanation or maybe even tutorial would defiantly help for beginners.

Can't scroll settings menu

Turn the app in landscape mode. Have a screen width that is to low to display the whole settings menu.

Try to scroll it so you can reach the lower options like notification on/off. At the moment there is no way to reach the option. The menu doesn't support scrolling.

Pls add this :/

Doesen't work

ReGeX does not start since the last upgrade on F-Droid. Android 5.1.1 .

Idea : Crowd solving regex

Hi, I've just discovered this app. It's awsome...
What do you think about creating a database of solutions submitted by the users ?

After a while, a website with a search engine could make available the best result for the public...

The public could also submit problems which can be dispatched in the game for the best players.

What do you think ?

Bye

explain game objective ingame

So what do you need to do? Imagine I haven't read the readme or the fdroid description. And just installed it because of its relation to regex.

Error requesting next task from server.

Error requesting next task from server. Please change game mode.

However, if I tap the "add" button with the redb server, the following toast appears:

Can connect.

Sometimes it just works, but most of the time it doesn't. I tried troubleshooting it, but it simply happens sometimes. I am connected to the network. Any hint on what I could do (I can debug it on Android Studio) would be appreciated!

Game freezes after first launch

The game runs perfectly on the first launch after installation, but after closing the game and launching it again it simply hangs with an empty screen

The log seems to be in a loop. Here is the last part:

"ReGeX wurde angehalten"[GER] ~"ReGeX was stopped/paused/..."[supposed English error]

Hi,

I am loving the game on Android.
But till now after a few tens or hundred puzzles I always got the Wiz/Android-Error "ReGeX wurde angehalten" which should be something like "ReGeX was stopped/paused/..." in English.
Only reinstall seems to help.

Any advice how I could find/give more information about this?
This is surely no nicely documented issue yet. ;)

Thanks for your work
Sincerely
Jonas

extend score display time

Please extend the score display time for those of us whose eyes do not jump and focus that quickly. One more second would be fine.

Question: why not matched

I think this should be correct what am I doing wrong?

Conditional Regel working?

When I enter
(C)(?(1)Y).
in the entry box I would expect that it matches
CY
But instead the number on remaining characters is displayed red, which I interprete as "Syntax error in their expression". What am I missing?

How many levels are there?

I'm stuck at 9. Also, in the level-success popup, it would be usefeful to see if you went up or down

Spaces are almost invisible

It is difficult to see if a word starts or end with a spece (you realize it because your pattern seems broken)

Option: disable vibration and/or sound

It is not possible to play the game while listening to music. It just always stops the music.

And the vibration gets annoying if you put your phone on a wooden or glass table while playing.

Unable to use template chars (such as ?) from regular keyboard

(I use Hackers' Keyboard )

Add string transform game mode

There could be string transformation mode that would display set of strings in two columns as it is now, but instead of asking player to match left strings and don't match right strings on right, it would ask them to transform right strings into left strings.

Regex input could be kept as is and use '/' to separate input from output or give two input fields to enter input and output regex.

Challenges could be randomly generated by generating random strings and randomly mangling them to create "transform to" column.

Transform tasks could constitute separate mode, or could be mixed with normal tasks.

Add "Extraction Game Mode"

As suggested on reddit the game should implement not only matching the whole string, but also splitting out a part. I would suggest it to start about level 7, with only pre or post strings on one side.

Stylistically it could be like ante- string -post with ante- and -post in a lighter color.

This would have to also be explained either in the start screen or when it appears for the first time

Screen rotation changes the current puzzle

If you rotate the screen to horizontal, and then back to vertical, the current puzzle changes to a new one.

All puzzles are easy to solve by using |

Scoring?

Is it just length? I notice sometimes that I get a score of 200+ for regex's that aren't particularly short, although I liked the solution better than a [xyz].+ type solution. Is there any weight given to the use of certain solutions / meta characters in scoring?

Most of the puzzles are easily solvable by excluding the chars present in the right side of screen.

Random language generation needed

I am excited for this game as I love solving regular expressions. In the real world, regexes allow you to match not just some finite set of words, but all possible words of a certain type. The puzzle and the fun is in recognizing the pattern that groups the words together so you can craft the perfect regex.

This game has promise, but its random problem generator only creates strings of characters with no rhyme or reason. I just played 66 rounds and got to level 10 and every single solution was "[abc].*" or a minor variant of it. It was boring because the type of problem never changed.

I think it would be much more fun if the set of words was created by randomly created regexes, finite state automata or hidden Markov models.

For example, if the game randomly creates "a+", the first level might look like:

Match: a aaaaaa aaaa
Not: b abba baa

As levels progress, instead of the words getting longer, the generating pattern will get more complex, randomly adding regex features like matching groups and alternation.

For example, perhaps the next level would increase the grammar (which letters are allowed) and the problem generated might be "[ab]",

Match: a b
Not: c

And then,

Match: aa abab bbbb
Not: a bab abba

If you make a list of regex features ordered by difficulty, you can add new ones in the mix after each level. That way the game would constantly feel like a significantly different challenge as new types of patterns appear.

Thanks for making what promises to be a great game.

no obvious way to exit welcome screen

When you start the app and see the welcome screen there is no obvious way to close it. Sure the back button works but it is means to go back. And in this context the last place you were was the app launcher not the game view.

There should be a close button, maybe an x in the corner or just another button at the end...

Just wanted to note the F-Droid app hasn't been updated in 3 years, not sure if there's anything that has been updated, or any security issues that need to be fixed. Thanks

Steps to reproduce

Use the code up to #8009ec commit.
Accomplish some task.
Leave the game and clear it from recent apps.
Try to play again.

Note that this also happened when I updated from the old version to this one. I can't remember if it happened on the previous version, but I think it didn't.

Character limits make the game too monotonous

example:
Match: x yuh
Don't match: tui op
Solution: x|yuh

Because of the character limit, I cannot use some longer, more ingenious solutions, instead I am stuck using "x|yuh" for almost all the solution.

Implement Tests

Due to issues like #20, we need tests to check if all is working as intended. Sadly I have not much experience with tests, so any help would be nice, in the meantime, I'm also going to look into it.

Show amount of solved problem

Just so the player knows about his her progress.

Translate to different languages

I am currently working on German and Serbo-Croation translation. Any help would be great.

Random mode: same string on both sides

Hi, I built the game half an hour ago (after updating the translations). On level 4 I have an "i" on both sides. Writing "i" colors both so there is no a hidden space or something like that.

ReDB is offline

hey! :-)
i am not sure this is the case, but it seems so to me (in the game, it tells me it is unable to connect).
i like the idea of your game, but as i already know regex, and would rather play with more complex, real-world challenges, i'd rather have something more... real then the random ones.
thanks for the game! :-) like the FOSS and design. :-)

HTTPS on regdb

Now regdb is without https. It's not good for 2016

Rewrite ReGeX in Kawa Scheme

The current code-base it unpleasant to work with, and I cannot use the necessary tools to properly maintain and test it.

I've recently been reading more about Kawa Scheme, a Scheme implementation based on the JVM that can be used to develop Android Applications.

Rewriting ReGeX in Kawa would allow for a much needed simplification and overhaul of the game modes, with a arguably more sane programming language that I don't need a massive IDE to use properly.

This issue will document the journey of porting ReGeX. When I get around to it, I shall also add a TODO list, collecting whatever has yet to be done.

Version 2.0 will be skipped (symbolically), and implementing this will directly result in version 3.0.

Update license to "GPLv2 and later" to solve conflict with Apache2 support libs

The app uses the Android support libraries, which are Apache2 licensed. However, plain GPLv2 is not compatible with it, but GPLv2+ (with the "and later" addition) is. Could you explicitly state this is the correct version, e.g. in the readme? The included license file covers both versions of the gplv2.

API Compatibility Issues

Dear developers,

We have recently developed a state-of-the-art static analysis tool for uncovering API compatibility issues in Android apps. Applying this tool to open source apps on F-droid, we have exposed a few instances of compatibility issues and submitting them to development teams for a fix.

For your app, we have found that this project has accessed the following APIs which are available only on an API level higher than the declared minSdkVersion and which are accessed without proper protection. In other words, if those APIs get called at runtime, it will trigger a NoSuchMethodError and thus result in a crash of the running application.

<android.app.Fragment: android.content.Context getContext()>:[23,25]

Note that, because of the nature of the static analysis, we cannot confirm whether the flagged APIs would actually be called at runtime (e.g., unreachable code). However, we still believe that those APIs, which may cause compatibility issues, should not be accessed or at least be accessed with proper protections.

In addition to the aforementioned APIs (i.e., backward-compatibility), which could cause app crashes if accessed, we have also identified that this project has also accessed some APIs that have been removed from the latest public SDK, making the app possibly suffer from forward-compatibility issues.

NONE

We would be very much appreciated if you can acknowledge to us that those reported APIs are indeed problematic for the project’s long-term stability. please let us know if you need any more information relating to this issue report.

game mode suggestion: paragraph extraction

paragraph extraction mode needs a text file to play(either online or local)
the game will select some random paragraphs in the file as the goal, the player have to extract all the needed paragraphs with one expression while not extracting anything else. length of regex isn't limited but longer regex results in lower score.

Count wrong when losing focus

When i lose focus (change to another app to see the cheatsheet),and return, the counting seems to go wrong.
In this picture the number is supposed to be zero, but it returned to nine.
