Naruto downloader from managreader.net

After reading Naruto upto chapter 520 (courtesy naruto with elisp) I was eager to read the rest. As of today the latest chapter is 570. I found mangareader.net after a bit of googling and was busy reading my way through the chapters. But, like before reading in the browser was not up to my taste. Currently the mcomix is the comic reader of my choice. So, I set about to write a script to automatically download the remaining chapters from mangareader.net. I do not know if its wrong to do so, the site does not have any terms of use :| So, I let it rip and now I'm busy reading... :)

Naruto with elisp

I just downloaded a huge Naruto (Manga) torrent which was organized like below

|- Chapter 001 to 010
|---- c001-p01.jpg
|---- c001-p02.jpg
|---- ...
|---- c010-p21.jpg
|---- c010-p22.jpg
|- Chapter 011 to 020
|- ...
|- Chapter 511 to 520
|- ...

I prefer to read my comics in cdisplay/comix which can read cbz/cbr formats. I was looking for an easy way of automating the process in elisp (buoyed by my previous success with the Luhnz algorithm). I was also itching to use this. My attempt at creating a script in one go was a failure and since I wanted to do it quick I used this

M-: (dotimes (i 52) (insert (format "cd \"Chapter %03d to %03d\"\n(dotimes (i 10) (insert (format \"\\\"C:\\\\Program Files\\\\7-Zip\\\\7z.exe\\\" a -tzip \\\"E:\\\\comics\\\\Naruto\\\\out\\\\%s.cbz\\\" c%s-*\\n\" (+ %d i) (+ %d i))))\ncd ..\n" (1+ (* i 10)) (* (+ i 10)) "%03d" "%03d" (1+ (* i 10)) (1+ (* i 10)))))

On running which I got this

cd "Chapter 001 to 010"
(dotimes (i 10) (insert (format "\"C:\\Program Files\\7-Zip\\7z.exe\" a -tzip \"E:\\comics\\Naruto\\out\\%03d.cbz\" c%03d-*\n" (+ 1 i) (+ 1 i))))
cd ..
cd "Chapter 011 to 011"
(dotimes (i 10) (insert (format "\"C:\\Program Files\\7-Zip\\7z.exe\" a -tzip \"E:\\comics\\Naruto\\out\\%03d.cbz\" c%03d-*\n" (+ 11 i) (+ 11 i))))
cd ..
cd "Chapter 021 to 012"
(dotimes (i 10) (insert (format "\"C:\\Program Files\\7-Zip\\7z.exe\" a -tzip \"E:\\comics\\Naruto\\out\\%03d.cbz\" c%03d-*\n" (+ 21 i) (+ 21 i))))
cd ..

Then positioning the caret at the first character for the dotimes line I recorded the following macro C-x ( C-k M-: C-y C-j C-k C-n C-n C-x ). This done, I ran the macro C-x e and held down the e till all occurrences were covered and I got this.

cd "Chapter 001 to 010"
"C:\Program Files\7-Zip\7z.exe" a -tzip "E:\comics\Naruto\out\001.cbz" c001-*
"C:\Program Files\7-Zip\7z.exe" a -tzip "E:\comics\Naruto\out\002.cbz" c002-*
...
"C:\Program Files\7-Zip\7z.exe" a -tzip "E:\comics\Naruto\out\010.cbz" c010-*
cd ..
...

I saved it as a bat file and let it loose and I had a neat little directory in which all the cbz files :). I'm sure there are more cleverer ways to accomplish this but, this was the easiest approach that I could think of (after a few failed attempts at nested inserts and let).
