Was it worth the time? Definitely not. Was fun though.

So, I use Anilist to keep track of my anime/manga list.
Usually, when I read manga online, there are various extensions to automatically track and update my manga progress like MALSync (the one I'm using, there should be more). My manga site of choice is Mangadex - they provide high quality images and no ads, pretty decent reader, it's a no-brainer choice. Unfortunately, they do not allow official rips. That's why sometime I would read my manga offline using my favourite manga reader MComix.

There are one problem with this method though...
MComix has not released any new version since 2016-02-12 (the last version they released was MComix-1.2.1). So integrating a native update client to sync your progress with a tracking site like Anilist is out of the question. Which means I don't really have any good option to update my manga progress when I read offline.

So there are two solutions to this:

1. Occasionally Alt-tab to Anilist and press the + button to update your progress. Super easy, super convenient.
2. Use the external command support feature of MComix to run an external command and make use Anilist's API to automate this process. And you can already guess what I chose to do.

mendo 0.2.1

A CLI program to update manga progress

USAGE:
    mendo [FLAGS] [SUBCOMMAND]

FLAGS:
    -h, --help       Prints help information
    -V, --version    Prints version information
    -v, --verbose    Sets the level of debug information verbosity

SUBCOMMANDS:
    auth      Authorizes mendo to update progress
    update    Updates manga progress

You need to authorize mendo to use the main feature of the program which is the update feature. To start the authorization process, simply type mendo auth in your terminal. It will open your browser and redirect you to Anilist page where you would press another green button Authorize to complete the process. That's it.
Note: If you somehow mess up something and need to reauthorize, you can use mendo auth --force to force mendo to reauthorize you.

Open MComix, File -> Open with -> Edit commands. Add a new external command, call it whatever you want.
And the command would be /path/to/mendo update %a. You can add a some -v to increase debug information logged to your data directory. You should find a directory named mendo in there. Refer to the table below.

So when you are done with the integration process, open your manga archives and read them like normal. When you come to a new chapter, press the assigned external button corresponding to mendo command. It will automatically update +1 to your manga progress. Yay.
NOTE: By default, the regex pattern ^(.*) (v?|c?)\d+ (most manga rippers use this naming convention) is used to get the manga title from the archived file. You can override this pattern with the optional flag --regexp (or -e for short). The manga title can be in their native name, romaji or english. As long as it's the first result when you search on Anilist it should work.
