+
+Mit diesem Tool kann man seine Anzeigen bei https://kleinanzeigen.de sichern.
+
+> [!IMPORTANT]
+> Diese Software wird jetzt bei Codeberg weitergepflegt: [Codeberg](https://codeberg.org/scip/kleingebaeck/).
+
+Es kann alle Anzeigen eines Users (oder nur eine Ausgewählte)
+inklusive der Bilder herunterladen, die in einem Verzeichnis pro
+Anzeige gespeichert werden. In dem Verzeichnis wird eine Datei
+`Adlisting.txt` erstellt, in der sich die Inhalte der Anzeige wie
+Titel, Preis, Text etc befinden. Bilder werden natürlich auch heruntergeladen.
+
+## ACHTUNG - SICHERHEITS-UPDATE
+
+Fertige vorcompilierte Programme älter als Version `v0.3.12` sind von
+Schwachstellen in der Behandlung von HTTP und Zertifikaten
+betroffen. Falls Du eine ältere Kleingebäck-Version im Einsatz hast,
+bitte update auf Version `v0.3.12` oder höher. Bitte lies auch die [Release Notes für
+v0.3.12](https://codeberg.org/scip/kleingebaeck/releases/tag/v0.3.12)
+für mehr Details.

+
+## Installation
+
+Das Tool hat keine weiteren Abhängigkeiten und erfordert auch keine
+Anmeldung oder ähnliches. Man kädt sich einfach die ausführbare Datei
+für seine Plattform herunter und kann direkt loslegen.
+
+### Installation des vorcompilierten Programms
+
+Auf der Seite [des letzten Releases](https://codeberg.org/scip/kleingebaeck/releases) findet man das Program für sein Betriebssystem und die Plattform (z.b. Windows + Intel)
+ 
+Es gibt 2 Varianten:
+
+1. Direkt das fertige Program für seine Plattform+OS herunterladen,
+   z.B. `kleingebaeck-linux-amd64-0.0.5`, nach `kleingebaeck`
+   umbenennen und in ein Verzeichnis kopieren, das im `PATH` ist,
+   (z.B. nach `$HOME/bin` oder als root nach `/usr/local/bin`).
+
+Um sicher zu gehen, dass an dem Program nicht verändert wurde, kann
+man die Signatur vergleichen. Für jeden Download gibt es eine dazu
+passende Signatur, in unserem Beispiel wäre das
+`kleingebaeck-linux-amd64-0.0.5.sha256`.
+
+Zum Verifizieren ausführen:
+
+```shell
+cat kleingebaeck-linux-amd64-0.0.5.sha25 && sha256sum kleingebaeck-linux-amd64-0.0.5
+```
+Man sollte zweimal den gleichen SHA256 Hash sehen.
+
+2. Man kann auch einen Tarball (tgz Dateiendung) herunterladen,
+   auspacken und mit GNU Make installieren:
+
+```shell
+tar xvfz kleingebaeck-linux-amd64-0.0.5.tar.gz
+cd kleingebaeck-linux-amd64-0.0.5
+sudo make install
+```
+
+### Installation aus dem Sourcecode
+
+Man muss eine funktionierende Go Buildumgebung in der Version 1.21
+installiert haben, um das Programm selber zu compilieren. GNU Make ist
+hilfreich, aber nicht unbedingt erforderlich.
+
+Um das Programm zu compilieren, muss man folgende Schritte ausführen:
+
+```shell
+git clone https://codeberg.org/scip/kleingebaeck.git
+cd kleingebaeck
+go mod tidy
+make # (oder make)
+sudo make install
+```
+
+### Docker image benutzen
+
+Ein fertiges Dockerimage mit der aktuellen Programmversion ist immer
+verfügbar. Man kann damit z.B. das Tool testen, bevor man es dauerhaft
+benutzen möchte.
+
+Um das Image herunterzuladen:
+```
+docker pull ghcr.io/tlinden/kleingebaeck:latest
+```
+
+Um kleingebäck im Image auszuführen und Daten ins lokale Filesystem zu
+sichern, kann man so vorgehen:
+
+```shell
+mkdir anzeigen
+docker run -u `id -u $USER` -v ./anzeigen:/backup ghcr.io/tlinden/kleingebaeck:latest -u XXX -v
+ls -l anzeigen/ein-buch-mit-leeren-seiten
+total 792
+drwxr-xr-x 2 scip root   4096 Jan 23 12:58 ./
+drwxr-xr-x 3 scip scip   4096 Jan 23 12:58 ../
+-rw-r--r-- 1 scip root 131650 Jan 23 12:58 1.jpg
+-rw-r--r-- 1 scip root  81832 Jan 23 12:58 2.jpg
+-rw-r--r-- 1 scip root 134050 Jan 23 12:58 3.jpg
+-rw-r--r-- 1 scip root   1166 Jan 23 12:58 Adlisting.txt
+```
+
+Hier wird der aktuelle User auf den User im Image gemappt und das
+lokale Verzeichnis `anzeigen` nach `/backup` innerhalb des Images
+gemountet.
+
+Die Optionen `-u XXX -v` sind kleingebäck Optionen. Ersetze `XXX`
+durch Deine tatsächliche kleinanzeigen.de Userid.
+
+Eine Liste verfügbarer Images findet man [hier](https://codeberg.org/scip/kleingebaeck/pkgs/container/kleingebaeck/versions?filters%5Bversion_type%5D=tagged)
+
+## Kommandozeilen Optionen:
+
+```
+Usage: kleingebaeck [-dvVhmoc] [<ad-listing-url>,...]
+Options:
+-u --user    <uid>      Backup ads from user with uid <uid>.
+-d --debug              Enable debug output.
+-v --verbose            Enable verbose output.
+-o --outdir  <dir>      Set output dir (default: current directory)
+-l --limit   <num>      Limit the ads to download to <num>, default: load all.
+-c --config  <file>     Use config file <file> (default: ~/.kleingebaeck).
+   --ignoreerrors       Ignore HTTP errors, may lead to incomplete ad backup.
+-m --manual             Show manual.
+-h --help               Show usage.
+-V --version            Show program version.
+
+If one  or more <ad-listing-url>'s  are specified, only  backup those,
+otherwise backup all ads of the given user.
+```
+
+## Konfiguration
+
+Man    kann    anstelle     von    Kommandlineoptionen    auch    eine
+Konfigurationsdatei  verwenden.  Sie  befindet  sich standardmäßig  in
+`~/.kleingebaeck`  aber man  kann  mit dem  Parameter  `-c` auch  eine
+andere Datei angeben.
+
+Das Format (TOML) ist einfach:
+
+```
+user = 1010101
+loglevel = verbose
+outdir = "test"
+```
+
+Im Source gibt es eine Beispieldatei `example.conf` mit Kommentaren.
+
+## Umgebungsvariablen
+
+Man kann darüber hinaus auch Umgebungsvariablen verwenden. Sie
+entsprechen den Konfigurationsoptionen, aber gross geschrieben mit dem
+Präfix `KLEINGEBAECK_`, z.B.
+
+```shell
+% KLEINGEBAECK_OUTDIR=/backup kleingebaeck -v
+```
+
+## Benutzung
+
+Um das Tool einsetzen zu können, muss man zunächst seine Userid bei
+kleinanzeigen.de herausfinden. Dazu ruft man am besten die Liste
+seiner Anzeigen auf, während man NICHT eingeloggt ist:
+
+https://www.kleinanzeigen.de/s-bestandsliste.html?userId=XXXXXX
+
+Der `XXXXX` Teil der URL ist die Userid.
+
+Trage diese Userid in der Konfigurationsdatei ein wie oben
+beschrieben. Gib ausserdem das Ausgabeverzeichnis an. Dann einfach nur
+`kleingebaeck` ausführen.
+
+Innerhalb des Ausgabeverzeichnisses wird sich dann pro Anzeige ein
+Unterverzeichnis befinden. Pro Anzeige gibt es eine Datei
+`Adlisting.txt`, die etwa so aussieht:
+
+```default
+Title: A book I sell
+Price: 99 € VB
+Id: 1919191919
+Category: Sachbücher
+Condition: Sehr Gut
+Created: 10.12.2023
+
+This is the description text.
+
+Pay with paypal.
+```
+
+Sowie alle Bilder.
+
+Das Format kann man mit der Variable `template` in der Konfiguration
+ändern. Die `example.conf` enthält ein Beispiel für das Standard Template.
+
+## Verhalten des Tools
+
+Es gibt einige Dinge über das Verhalten von kleingebäck, über die Du
+Bescheid wissen solltest:
+
+- alle HTML Seiten und Bilder werden immer heruntergeladen
+- es wird ein (konfigurierbarer) Useragent verwendet
+- HTTP Cookies werden beachtet
+- bei Fehlern wird dreimal mit unterschiedlichem Abstand erneut
+  versucht
+- Bilder Downloads laufen parallelisiert mit leicht unterschiedlichen
+  zeitlichen Abständen ab
+- Gleich aussehende Bilder werden nicht überschrieben
+
+Der letzte Punkt muss genauer erläutert werden:
+
+Wenn man bei Kleinanzeigen.de eine Anzeige einstellt und Bilder
+postet, werden diese dort in ihrer Grösse reduziert (durch Kompression
+und Verkleinerung der Bilder usw.). Diese reduzierten Bilder werden
+dann von kleingebäck heruntergeladen. Falls Du Deine original Bilder
+behalten hast, kannst Du diese danach in das Backupverzeichnis
+kopieren. Bei einem erneuten kleingebäck-Lauf werden diese Bilder dann
+nicht überschrieben.
+
+Wir verwenden dafür einen Algorythmus namens [distance
+hashing](https://github.com/corona10/goimagehash). Dieser Algorithmus
+prüft die Ähnlichkeit von Bildern. Diese können in ihrer Auflösung,
+Kompression, Farbtiefe und vielem mehr manipuliert worden sein und
+trotzdem als das "gleiche Bild" erkannt werden (wohlgemerkt nicht "das
+selbe": die Dateien sind durchaus unterschiedlich!). Bis zu einer
+Distance von 5 überschreiben wir keine Bilder, weil wir dann davon
+ausgehen, dass das lokal Vorhandene das Original ist.
+
+Bitte beachte aber, dass dies KEIN Cachingmechanismus ist: die Bilder
+werden trotzdem immer alle heruntergeladen. Das muss so sein, da wir
+uns nicht die Dateinamen anschauen können, da kleinanzeigen.de diese
+nämlich zu Zahlen umbenennt. Und die Dateinamen können sich auch
+ändern, wenn der User in der Anzeige die Bilder umarrangiert hat.
+
+Du kannst dieses Verhalten mit der Option **--force** ausschalten. Du
+kannst ausserdem mit der Option **--ignoreerrors** auch alle Fehler
+ignorieren, die beim Bilderdownload auftreten könnten.
+
+## Documentation
+
+Die Dokumentation kann man
+[online](https://codeberg.org/scip/kleingebaeck/raw/branch/main/kleingebaeck.pod)
+oder lokal lesen mit: `kleingebaeck --manual`. Hat man das Tool mit
+dem Tarball installiert, funktioniert auch `man kleingebaeck`.
+
+## Kleingebäck?
+
+Der Name kommt von "kleinanzeigen backup", verkürzt "klein back", das
+englisch ausgesprochene "back" (deutsch bäck) führt dann zu "Kleingebäck".
+
+## Wo bekommt man Hilfe
+
+Obwohl ich gerne von kleingebäck Benutzern in privaten Mails höre, ist
+das doch der beste Weg, die Anfrage zu übersehen und zu vergessen.
+
+Um einen Fehler, ein unerwartetes Verhalten, eine Feature Request oder
+einen Patch zu übermitteln, eröffne daher bitte einen Issue unter:
+https://codeberg.org/scip/kleingebaeck/issues. Danke!
+
+Bitte gebe den fehlgeschlagenen Befehl an, rufe es auch mit Debugging
+`-d` auf.
+
+## Ähnliche Projekte
+
+Ich konnte kein Projekt finden, das speziell dafür geeignet ist,
+Anzeigen bei kleinanzeigen.de zu sichern.
+
+Aber es gibt ein Projekt, mit dem man ebenfalls Backups erstellen
+kann:  [kleinanzeigen-bot](https://github.com/Second-Hand-Friends/kleinanzeigen-bot/).
+Aber Vorsicht: kleinanzeigen.de bekämpft Bots aktiv, mit diesem hier
+gibt es regelmäßige Probleme, z.B.: 
+[issue](https://github.com/Second-Hand-Friends/kleinanzeigen-bot/issues/219).
+Das Hauptproblem ist, dass diese Art von Bot sich mit Deinem Account
+aktiv einloggt und mit der Seite interagiert. Damit kann die Firma die
+Aktivitäten recht einfach Deinem User zuordnen und diesen **sperren**!
+Also sei bitte vorsichtig!
+
+**Kleingebäck** erfordert keinen Login, es verwendet lediglich die
+öffentlich verfügbare Webseite und ruft diese auf, wie ein normaler
+Browser. Tatsächlich gibt es meiner Meinung nach keinen Unterschied zu
+einem Browserclient: beide laufen auf Anwenderseite auf Initiative
+eines Benutzers. Und mit welchen Browser ich eine Webseite aufrufe,
+bleibt immer noch mir überlassen und muss mir nicht von irgendwem
+vorgeschrieben werden. Das schliesst die Verwendung von Kleingebäck
+mit ein.
+
+Hinzu kommt, dass dieses Tool nicht dazu gedacht ist, rund um die Uhr
+zu laufen. Man ruft es ab und zu mal auf, wenn man halt neue Anzeigen
+eingestellt hat, vielleicht einmal die Woche oder so. Man weiss ja
+selber, wann man was geändert hat. Man benötigt trotzdem den Zugriff
+mit dem Browser oder der mobilen App um Kleinanzeigen.de verwalten zu
+können.
+
+Meiner Ansicht nach ist das Risiko also sehr minimal, es handelt sich
+meiner Meinung nach auch nicht um eine Verletzung der AGBs dort. Aber
+das ist nur meine persönliche Meinung, bitte beachtet das. Am Ende
+müsst Ihr selbst einschätzen und beurteilen wie hoch Ihr das Risiko
+seht und ob Ohr es eingehen möchtet. Für eventuell auftretende
+Konsequenzen bin ich nicht verantwortlich. Siehe auch [GPL Lizenz](LICENSE).
+
+Es       gibt      noch       ein      weiteres       Tool      namens
+[kleinanzeigen-enhanded](https://kleinanzeigen-enhanced.de/).  Das ist
+eine    kostenpflichtige     vollständige    Anzeigenverwaltung    für
+Profinutzer. Man  muss eine  monatliche Abogebühr bezahlen.   Das Tool
+ist  als  Browsererweiterung  für  Google  Chrome  implementiert,  was
+erklärt,  warum sie  Anzeigen  erstellen, ändern  und löschen  können,
+obwohl es  gar keine  öffentliche API gibt.   Sieht nach  einer netten
+ausgereiften Lösung aus. Mit Backups.

+## Installation
+
 The   tool  doesn't   need   authentication  and   doesn't  have   any
 dependencies.  Just  download the  binary for  your platform  from the
 releases page and you're good to go.
 
-The releases also include a handy tarball which you can use to install
+### Installation using a pre-compiled binary
-the tool  system-wide including the  manual page. Just extract  it and
+
-type: `make install`.
+Go            to             the            [latest            release
+page](https://codeberg.org/scip/kleingebaeck/releases)     and
+look for your OS and platform. There are two options to install the binary:
+
+1.    Directly   download    the    binary    for   your    platform,
+   e.g. `kleingebaeck-linux-amd64-0.0.5`, rename  it to `kleingebaeck`
+   (or  whatever  you  like  more!)  and put  it  into  your  bin  dir
+   (e.g. `$HOME/bin` or as root to `/usr/local/bin`).
+
+Be sure to verify the signature of the binary file. For this also download the matching `kleingebaeck-linux-amd64-0.0.5.sha256` file and:
+
+```shell
+cat kleingebaeck-linux-amd64-0.0.5.sha25 && sha256sum kleingebaeck-linux-amd64-0.0.5
+```
+You should see the same SHA256 hash.
+
+2.  You  may  also  download  a  binary  tarball  for  your  platform,
+   e.g.  `kleingebaeck-linux-amd64-0.0.5.tar.gz`,  unpack and  install
+   it. GNU Make is required for this:
+   
+```shell
+tar xvfz kleingebaeck-linux-amd64-0.0.5.tar.gz
+cd kleingebaeck-linux-amd64-0.0.5
+sudo make install
+```
+
+### Installation from source
+
+You will need the Golang toolchain  in order to build from source. GNU
+Make will also help but is not strictly neccessary.
+
+If you want to compile the tool yourself, use `git clone` to clone the
+repository.   Then   execute   `go    mod   tidy`   to   install   all
+dependencies. Then  just enter `go  build` or -  if you have  GNU Make
+installed - `make`.
+
+To install after building either copy the binary or execute `sudo make install`.
+
+### Using the docker image
+
+A pre-built docker  image is available, which you can  use to test the
+app without  installing it. To download:
+
+```shell
+docker pull ghcr.io/tlinden/kleingebaeck:latest
+```
+
+To execute kleingebaeck  inside the image and download ads  to a local
+directory, do something like this:
+
+```shell
+mkdir myads
+docker run -u `id -u $USER` -v ./myads:/backup ghcr.io/tlinden/kleingebaeck:latest -u XXX -v
+ls -l myads/ein-buch-mit-leeren-seiten
+total 792
+drwxr-xr-x 2 scip root   4096 Jan 23 12:58 ./
+drwxr-xr-x 3 scip scip   4096 Jan 23 12:58 ../
+-rw-r--r-- 1 scip root 131650 Jan 23 12:58 1.jpg
+-rw-r--r-- 1 scip root  81832 Jan 23 12:58 2.jpg
+-rw-r--r-- 1 scip root 134050 Jan 23 12:58 3.jpg
+-rw-r--r-- 1 scip root   1166 Jan 23 12:58 Adlisting.txt
+```
+
+We map the local user to the one inside the image so the permission
+will match. You'll need to create the directory first before executing
+docker run. And the local directory `myads` will be mapped to
+`/backup` inside the container.
+
+The options `-u XXX -v` are kleingebaeck options, replace `XXX` with
+your actual kleinanzeigen.de user id.

+## Tool Behavior
+
+There are a bunch of things you might want to know about the behavior
+of the kleingebäck tool:
+
+- all HTML pages and IMAGEs are always being downloaded
+- we use a (customizable) user agent
+- we respect HTTP cookies
+- in the case of an error, the tool does 3 retries, the time it waits
+  between tries is longer for each retry
+- image download is parallized using small time differences to look
+  more natural
+- same images are not being overwritten on subsequent download
+
+
+The latter needs to be elaborated a bit more:
+
+If you publish an ad on kleinanzeigen.de and post images, those images
+will be reduced in size by the site (by compressing and down sizing
+them). This reduced images will be downloaded by kleingebäck. However,
+you may still own the original images and may want to put them into
+that backup directory so that you have all things for one ad together.
+
+You can easily do that, because kleingebäck won't overwrite those
+original images. It uses something called a distance hash using
+[goimagehash](https://github.com/corona10/goimagehash). This
+algorithmus checks the similarity of images. If an image has been
+resized it is still very similar to the original one. We accept a
+maximum of a distance of 5, everything above leads to overwrite.
+
+This works with resizes, cropped and otherwise manipulated images as
+long as the image still shows the original contents good enough.
+
+Also note, that this is NOT a caching mechanism: the images will be
+downloaded anyway during each run. We also can't look at the file
+names because kleinanzeigen.de renames all images to numbers. And
+those might even change if the user re-arranges the images.
+
+You can override this behavior using the **--force** option. Another
+option, **--ignoreerrors**, can be used to ignore all kinds of image
+errors.

+## Related projects

+I could not find any projects specifically designed to backup
+kleinanzeigen.de ads, however there's a bot project which is also able
+to download ads:
+[kleinanzeigen-bot](https://github.com/Second-Hand-Friends/kleinanzeigen-bot/). However,
+be aware that kleinanzeigen.de is actively fighting bots! Look at this
+[issue](https://github.com/Second-Hand-Friends/kleinanzeigen-bot/issues/219). The
+problem with these kind of bots is, that they login into your account
+using your credentials. If the company is able to detect bot activity
+they can associate it easily with your account and **lock you
+out**. So be careful.
+
+**kleingebäck** doesn't need to login, it just accesses public
+available web pages. Kleinanzeigen.de could hardly do anything against
+it, once because it is legal. There's no difference between a browser
+and a commandline client. Both run on the clientside and it is not
+kleinanzeigen.de's decision which software one uses to access their
+pages. And second: because you can use it to download any ads, not
+just yours. So it is not really clear if the activity is associated in
+any way with the ad owner. In addition to that comes the fact that
+kleingebäck is just a backup tool. It is not intendet to be used on a
+daily basis. You cannot use it to view regular ads or maintain your
+own ads. You'll need to use the mobile app or the browser page with a
+login. So, in my point of view, the risk is very minimal.
+
+There is another Tool available named [kleinanzeigen-enhanced](https://kleinanzeigen-enhanced.de/). It is a complete Ad management system targeting primarily commercial users. You have to pay a monthly fee, perhaps there's also a free version available, but I haven't checked. The tool is implemented as a Chrome browser extension, which explains why it was possible to implement it without an API. It seems to be a nice solution for power users by the looks of it. And it includes backups.
