the only check maybe to make sure the proper endings do not end up with the proper beginnings so the real proverb does not get displayed. If that match is had then call for one of them to redo the return value.

You describe the code of my program. Only that the two-dimensional array that I actually use, facilitates everything a bit. But I do not understand the question “What is so hard about that?” as it does not relate to anything previously mentioned in this thread.

I like the idea of a self-improving program, although I do currently not know what “run through AI” would mean. AI necessitates an algorithm, necessitates that a living person and programmer has a clear idea on what a “good” phrase must look like which is quite a daring exigence when you deal living languages. That is the real challenge with this kind of program or game.
I should try creating indices from binary shift operations and will try to understand the results. After that, either wisdom will strike or I will just use more color in the output...

What is to improve on? It is just a simple arrangement of array and the use of random. Put it in a GUI with mouse support?

A few ideas have been presented in this thread which I will consider. The original question has not been exactly technical and most of the contributors have understood that.

improvements:

separate the german and english man pages completely. in its current state, the german man page is confusing.
add a FILES section (e.g., where are the results of down/upvotes stored, where are manually added proverbs stored, is there a config file...)

feature request:

config options for coloured frame / no frame - ask or don't ask for up/downvotes - display / don't display the countdown etc.

Can you elaborate, please?
AFAIK, there is no way to have man-pages installed automatically by executing the gem installation; thus, it is anyway up to the user to install the man-pages to the pertinent directories. As the English man page is called proverbs.6.gz and the German one sprichwoerter.6.gz I have a problem to understand the issue... But this is important, the current way to handle the documentation is definitely unsatisfactory.

Quote:

For the time everything is in .proverbs... AH!!! Sorry. You talk about the man-page. “Acknowledged and WILCO”.

Quote:

[*]config options for coloured frame / no frame - ask or don't ask for up/downvotes - display / don't display the countdown etc.

This will make the option-parser appear less overhead ...

There is one request missing, but I have implemented it already:
Honor interrupts (Strg+C, +D) and a push on the ESC-button alike to interrupt the count-down.

oh, i have no problem executing

Code:

man ~/.gem/ruby/2.6.0/gems/Sprichwoerter-1.3/doc/man/sprichwoerter.6.gz

but this man page should refer to the german version only, methinks.
to clarify, I struck out what, IMO, is superfluous (and confusing):

Code:

SPRICHWOERTER(6) Games SPRICHWOERTER(6)

NAME
Sprichwoerter - Kombiniert Anfänge und Enden von Sprichwörtern zu neuen, meist sinnlosen,
Sprichwörtern.

Proverbs - Der englische Name für das gleiche Programm.

PROGRAMMAUFRUF ENGLISCH UND DEUTSCH
proverbs oder sprichwoerter

proverbs add singular "A watched pot" "never boils"

proverbs add plural "cheaters" "never prosper"

sprichwoerter neu singular "Ein König mit Krone" "ist besser als ohne"

sprichwoerter neu plural "Hunde, die bellen" "beißen nicht"

proverbs -h (--help) or sprichwoerter -h (--help)

BESCHREIBUNG
Das Programm kombiniert die Anfänge und Enden von zufällig aus einer Liste ausgewählten
Sprichwörtern. Das Ergebnis ist ein Satz, der immer noch als eine Art "Sprichwort" erkennbar
ist, allerdings ohne den Anspruch, eine wirkliche Information zu vermitteln, geschweige denn
"Weisheit".

Ja. Eine lustige Zeitverschwendung. Sie können das Programm "Sprichwörter" zum Beispiel aus
Ihrer .bashrc Datei aufrufen.

Wenn Sprichwörter ohne Argumente von der Kommandozeile gestartet wird, erzeugt es ein neues
Sprichwort und zeigt es an. Führen Sie statt dessen proverbs aus, um englische Sprichwörter
zu generieren.

Sie können ein angezeigtes Sprichwort noch positiv bewerten, bevor das Programm sich been‐
det.

Der Benutzer kann echte, originalgetreue Sprichwörter zur Standardliste hinzufügen, indem
eine der sprachspezifischen Optionen verwendet wird (im März 2017 sind nur englische oder
deutsche Sprichwörter unterstützt). Die neuen Sprichwörter müssen einigen Bedingungen
genügen.

OPTIONEN
list bewirkt die Anzeige einer Liste von bisher positiv bewerteten, generierten
Sprichwörtern.

SPRICHWÖRTER ZUR LISTE HINZUFÜGEN
Zur Zeit der Redaktion dieses Dokuments (Februar 2017) müssen Sprichwörter dem im Folgenden
beschriebenen Muster folgen:

"Jemand oder etwas" | "tut oder ist etwas"

Führen Sie das Programm einfach ein paar Mal auf der Kommandozeile aus, um diese Ein‐
schränkung zu verstehen.

neu (oder Englisch: proverbs add)
neu singular "Beginn" "Ende" fügt das originale Sprichwort "Beginn Ende" zur Liste
der verfügbaren Sprichwörter hinzu. singular zeigt an, dass das Subjekt im originalen
Satz (in "Beginn") im Singular steht. Dies vermeidet Grammatikfehler im generierten
Ergebnis und hilft, die "Illusion" eines "echten" Sprichworts aufrechtzuerhalten.

neu plural "Beginn" "Ende" fügt das originale Sprichwort "Beginn Ende" zur Liste der
verfügbaren Sprichwörter hinzu. plural zeigt an, dass das Subjekt im originalen Satz
(in "Beginn") im Plural steht. Dies vermeidet Grammatikfehler im generierten Ergebnis
und hilft, die "Illusion" eines "echten" Sprichworts aufrechtzuerhalten.

(...) etc.

but I have implemented it already

so is this the current version:

How do I uninstall old versions with this manual install method?

This is just another example for my continuously misunderstanding plain English. I thought “separating” referred to the man-page files rather than their content. Got it now.

I do not know how you have installed it. Usually, if you do not use the gem utility to download & install in one go, you install from a gem-file with the option -l or --local:

Code:

user@machine:~$ sudo gem install [path]/package.gem -l

For the time, I do not use rubygems.org, so this is the best way to install the packages that I linked above.

To uninstall, you just execute

Code:

sudo gem uninstall package

and in the case of Sprichwoerter:

Code:

user@machine:~$ sudo gem uninstall Sprichwoerter

If there are several versions installed on the same system and for the same ruby-version, gem uninstalls each of the installed packages. To restrict the process to just one version, name it with the -v option:

Code:

sudo gem uninstall Sprichwoerter -v 1.3

In addition, you can handle ruby-gems like self-compiled programs with the Porg utility and then use Porg also to remove these packages again.

having read down a few post, separating the the languages is a good idea, maybe creating a menu to pick which language one wants to use, would then be the next logical line of thought.

as suggested a GUI where it could be a dock app, or a widget in the more modern Desktop like cinnamon, MATE and such that uses them. runs off a timer so it changes the output at a user specified time, or on the click of the mouse. That way one would not have to keep opening another terminal to read another one.

It is hard to tell what is useless, and even harder to tell when it is a waste of time. When the ancients were exploring what happened when they rubbed wool against amber, which we now understand as the separation of electric charge, they probably thought it was useless. Who knew it began a journey that would someday lead to electric power and information technology?

I installed all 3 versions with gem to my $HOME (so no sudo required) but trying to uninstall the older ones, i get:

Code:

$ gem list
(...)
Sprichwoerter (1.4, 1.3, 1.2)

$ gem uninstall Sprichwoerter -v 1.3

(a quick search for the error message seems to suggest that the problem is in your code, but i could be wrong there; ruby is unknown land to me)

I find your posts in this thread rather useless; if I were you, I'd go try and find something useful to do.

exactly, working on something useless is a waste of time. though suggesting making it into a gui app is not exactly useless, but adds to it ability to be seen more often without having to open a new terminal each time to see a new one displayed. but yeh whatever dude. its your option... no sleep lost here over it.

The error is new to me, but as I have also never installed a gem to my home-directory only, can you confirm that you have the same problems, when you execute the command with sudo anyway, as if it were necessary..??

The way that the Error is presented, makes me assume a problem with the gem-utility itself. As RDoc is mentioned, I bet that the tool tries to remove API-documentation which could have been installed with the package. In this case and remembering all the awkward things that happen with Ruby, sometimes, the installation-path to this kind of API-documentation may still be a system-wide setting.

Hence my many words to just say: try sudo anyway. No guarantee. But then again.., I did also not explicitly prepare any inline-documentation for RDoc. So there should also be nothing to uninstall...

Edit: Also make sure that you use the --user-install option for the call to gem uninstall as well! Otherwise, gem will try to remove gems from the global gem-folders. I just tried that for the first time and it worked as I expected.

Good luck.

At your place, I would manually remove the gem-directory, then re-install the gem with the --user-install option. If this works, try to uninstall it once again.

Code:
