Application not responding

[francesco-kriegel]

This might be a chance to advertise my re-implementation of ConExp, which I named "ConExpFX". You can find it on my GitHub page, both as source code but also as packaged installers for the major platforms.

Source code: https://github.com/francesco-kriegel/conexp-fx Installers: https://francesco-kriegel.github.io/conexp-fx/download.html

All FCA-related functions should work properly.

That sounds great! But when I run it using conexp-fx-5.5.1-SNAPSHOT-jar-with-dependencies.jar I get:

Also, I'd like it to support CSV import and export, choosing ',' or ,';' as the delimiters.
If that's possible. Thanks!

My first guess is that you use an unsupported Java version. I developed it with Oracle JDK8u192. Please try it with this version, or rather use one of the installers that come packaged with the right Java version, see https://francesco-kriegel.github.io/conexp-fx/download.html

Here are the specific download links for the latest versions:

• MacOS: https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-09-12/Concept%20Explorer%20FX-5.5.1.dmg
• Linux (RPM): https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-09-12/concept-explorer-fx-5.5.1-1.x86_64.rpm
• Linux (DEB): https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-09-12/concept-explorer-fx-5.5.1.deb
• Windows: https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-09-12/Concept%20Explorer%20FX-5.5.1.msi

Yikes, I just recognized that the latest versions do indeed not respond.

What works (on my computer) are the versions of 2019-03-23.

• MacOS: https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-03-23/Concept%20Explorer%20FX-5.5.1.dmg
• Linux (RPM): https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-03-23/concept-explorer-fx-5.5.1-1.x86_64.rpm
• Linux (DEB): https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-03-23/concept-explorer-fx-5.5.1.deb
• Windows: https://lat.inf.tu-dresden.de/~francesco/conexp-fx/download/5.5.1-SNAPSHOT/2019-03-23/Concept%20Explorer%20FX-5.5.1.msi

It might help to delete the configuration file .conexp-fx.xml from your user's home directory after the first start of the app, and then start it again. (There might be some paths stored that are local to my machine.)

PS: After a formal context has been loaded or newly created, you can display the lattice, context, etc. by selecting the according entry in the left column. If you want to see lattice and context side by side, then use a multi-selection (depends on your OS, on MacOS one holds the Command button for that).

I found the issue and fixed the bug. The latest version in the repository should work fine. However, I cannot provide installer packages as I shutdown my build servers. As far as I remember, the functionality that is concerned with FCA has not changed since the above versions of 2019-03-23.
