[SCRIPT] RetroPie Limit Last Played Games

MadHorse

@hiulit No problem mate, I will be happy to test the new version.
Thank you and happy holiday :)

hiulit

Version 2.1.0 of RetroPie Limit Last Played Games is here!

Added

Dialog asking if the user wants to restart EmulationStation when the script is done.
Output message for the games that will be shown in the 'last played' section.

Fixed

When there are duplicated <lastplayed> tags in different games the script crashes. Now, if the scripts find duplicates, it looks for the game's name (it should be different).

Thanks to @cyperghost for the restart function and @MadHorse for testing the script.

Updated the documentation for v2.1.0 - 2018-09-12 in the first post.

Hi @hiulit,
I'm so sorry, but checking the name introduced two more trouble.
If the name contain a ' single quote, it will complain because it Failed to compile select expression

Number of 'last played' games to limit is set to '10'.

daphne
------
'gamelist.xml' for 'daphne' found!

'gamelist-backups.xml' for 'daphne' created successfully!
Invalid predicate: /gameList/game[name='Dragon's Lair II: Time Warp (US v3.19)']/playcount

> Removing the 'last played' games surplus for 'daphne' ...
ERROR: There aren't enough 'last played' games to remove.
Try lowering the '--nth' number.
Now it's set to '10' and there are only 4 games in 'daphne'.

Daphne gamelist.xml contains 6 played games, but 2 games are not counted beacuse of the XSLT-with-param: Failed to compile select expression.

The other error is, if there are more games with the same name, it will give you another error

Number of 'last played' games to limit is set to '10'.

amiga

ERROR: There aren't enough 'last played' games to remove.
Try lowering the '--nth' number.
Now it's set to '10' and there is only 1 game in 'amiga'.

and instead of the same lastplayed date and time, finding more games witht he same name is easier, you may have multiple version of the same game, for example you may have the same Amiga games on CD32,CDTV, ADF or for example in many languages, but when you scrape the games, you will have the same name for every version of the game unless you don't manually change it.
One las note, the 2 amiga games with the same name, didn't have the same lastplayed date

		<desc>Turrican II: The Final Fight is a platformer/shooter as typically seen on consoles, but designed for home computers from the ground up.

Its plot is - naturally - very simple: an evil mega-robot called The Machine attacks the United Planets Ship Avalon 1, slaughtering all who resist. All - except Bren McGuire, who manages to escape and slips into the experimental Turrican bionic armor. As Turrican, he strives to show The Machine who's the boss.

Unlike other games of its type, this game contains three levels of horizontal shooter action in the spirit of R-Type or the developers' own Katakis. Six large worlds are to be explored, where you are basically free to go everywhere you want, since there is no automatic scrolling and the levels are packed with hidden extra lives and weapons. All those levels are very different: the first one in the rock desert is pretty colorful with parallaxing rainbow background and happy music, while the following worlds get darker and darker.</desc>

I beg your pardon, if it wasn't for me, you made a perfectly working script unless someone don't mess with the gamelist.sml file.
I'm so sorry, may I help you in any way ?

hiulit

@madhorse whooops, it's getting tricky! Haha! Would you mind copying a couple of your gamelists into pastebin.com or something similar so I can test with real game lists? In the virtual machine where I develop the scripts I only have a couple of games to test.

The first issue involving the characters, I think I can escape them so it doesn't crash. The second one needs a little bit more of testing.

Thanks a lot for helping me test the script, btw!

hiulit

@madhorse your Daphne and Amiga game lists would be enough, I think.

No Problem,
This is the Daphne Gamelist and this is the Amiga Gamelist

Thanks a lot for helping me test the script, btw!

Thanks to you for your work and for helping us to Limit the Last Played list :)

Retropie Limit Last Played Games v2.1.1 is out!

CHANGELOG

Fixed

Issue with duplicate game names but different <lastplayed> tags in gamelist.xml. Now the script takes both the game name and its <lastplayed> tag to avoid duplicates. If there are more than one game with same name and <lastplayed> tag, the script won't work.
Escape game names with single quotes in gamelist.xml.
Escape ampersands (&) in gamelist.xml.

@MadHorse all your issues should now be fixed! :P

EDIT: Until you find more, hehe! ;)

MadHorse

AND THE WINNER IS @hiulit :D

You did it man, I made some fast test with the new version and it's working perfectly, it' s awesome.
Now, because I'm a BAD guy, i tried to trick the script and made a gamelist with 2 exactly duplicate games, same name and same date, obviously the script gave an error, and then it completed the work.

Anyway, if someone has messed up the gamelist.xml so badly is what I-(he) deserve :)))

You are the best, thank you for your hard work, i love your script.

MadHorse

Hi @hiulit I'm here again, unfortunately for another bug.
Usually in the gamelist.xml the & character is written as &, probably there is something tricky with the escape of & because after you execute the script, it will transform it to &amp;, if you execute it another time you will get &amp;amp;
I'm so sorry to bring you bad news.

hiulit

@madhorse Hey! Yeah, totally my bad... Such a noob thing to do :( Or in this case, NOT to do..

I only check for unescaped & because in one of your gamelist.xml there were a lot of them and the software that parses the xml, which is xmlstarlet, was crashing because of that. So I assumed that scrapers would always add the unescaped & and I didn't take into account that it was possible for some scrapers to have the escaped version &.

I'll fix it asap.

Thanks for the heads up! ;)

New RetroPie Limit Last Played Games 2.1.2 is out!

@MadHorse if you could give it a try.... hehe! ;) Thanks!

CHANGELOG

[2.1.2] - 2018-09-20

Fixed

Escape special characters function.

Added

Validate XML function.

MadHorse

@hiulit hi, I made a quick test and now the & and & aren't changed, great work.
I will do some more test hoping to not find more bugs, I don't want you to hate me :)

Thank you very much, you and your script are awesome

hiulit

@madhorse Cross fingers :P

You are very welcome. I think you and I are the only ones using this script, haha!
