 2 | # WAPPEN's NHentai Tracker Extension
 3 | A Chrome extension to help you keep track of read book number.
 4 | Display badge over all book covers. Never got lost in search result again!
 5 | 
 6 | ![Preview](preview/preview.jpg)
 7 | ![Preview](preview/preview2.png)
 8 | ![Preview](preview/preview3.jpg)
 9 | 
10 | ### Features
11 | - Mark book as READ or IGNORED and display them over search result to quickly skim for new book to read.
12 | - Also auto mark as READ when you go into any of its page to read.
13 | - Mark as read later for reading list.
14 | - See [changelog.md](changelog.md) for change list.
15 | 
16 | ### Chrome
17 | Chrome Store: **Sorry none yet!** It needs to pass some ~~fapping~~ err I mean QA testing first.
18 | 
19 | ### Firefox
20 | I'm never intended to port to FF yet. Sooooorry! (CHECKMATE FF users!)
21 | 
22 | ------
23 | 
24 | ### Installing
25 | - As this is not published to store, the only way to install is via developer mode.
26 | - Download this entire repo, top right of this web page 'Code' button -> download zip (.zip) 
27 | - Unzip it to some folder, but dont unzip your pants yet, still some more steps to go.
28 | - Go into Chrome extension tab, enable developer mode (upper right).
29 | - Select load unpacked extension (upper left).
30 | - Point the to folder where you unzip it, where "manifest.json" is. (manifest.json wont show on dialog, that's ok, just select the folder)
31 | - Extension is installed as "NHentai Tracker". 
32 | - If you want more help regarding above steps, search for something like **Chrome install unpacked extension**.
33 | - Unzip your pants, go to NHentai.
34 | - What you can do next:
35 |   - Open extension option page by clicking extension badge. Import your favorite list. (Must be logged in)
36 |   - (Advanced) Export past browsing history and import to extension to scan for past visit. Read more below.
37 | 
38 | ### Pulling past visit from history
39 | Extension can do it in 2 ways, none of them are automated, so you need some work.
40 | - Google takeout (not much detailed history though, I pulled only a few out of it), to start, google something like "google export browsing history".
41 | - Or you export current Chrome history (note that [chrome will only hold up to 3 months of history locally](https://superuser.com/questions/364470/), which is stupid if you ask me)
42 | - I used this extension, [History Trends Unlimited](https://chrome.google.com/webstore/detail/history-trends-unlimited/pnmchffiealhkdloeffcdnbgdnedheme) which crunch history and further saving it longer than 3 months limit. 
43 | Anyway, if you just installed this Unlimited extension, you still have no way to bring back your history beyond that 3 months anyway.
44 | - If you have history exported from **History Trends Unlimited**, scan it in NHTracker's setting page in the second file submit section.
45 | 
46 | ### Upgrading
47 | - Upgrading from previous version, just redownload this again and unzip to same location.
48 | - In your chrome extension page, click the circle arrow (reload extension) and you are done. Notice the version number should changed.
49 | - If you have any NH tab already open you need to refresh them once for the new version to take effect.
50 | 
51 | ------
52 | 
53 | ### Q&A
54 | **Why there are 'READ' and 'IGNORED' book state? What's the difference?**
55 | - The 'IGNORED' state is used to mark book as **"Checked that out but passed"** rather than **"I read that! (to the end!)"**. 
56 | - Example usage is using IGNORE tag on the book you totally not interested in. 
57 | - Or another usage is to mark them on another sibling books. (incompleted, reuploaded, low quality, bad translation, etc)
58 | - Ignored book will not show in read book listing.
59 | - Ignored bool will colored differently in search result.
60 |   
61 | **I want XX YY ZZ feature! Make it!! plzzzz**
62 | - If it sounds good, pitch it to me via issue page.
63 | - Else you have to learn HTML+JavaScript and do it yourself. :P
64 | 
65 | **What is it inspired from?**
66 | - I noticed that browser always mark visited link, like from blue to purple for an eon since internet started, but now in 2022 I have trouble looking at doujin search result, how comes?
67 | - So I searched chrome extension store and github for something like this, hoping that some gentleman would already made it.
68 | - But I found stuff like extension that let you highlight NH number and jump to the site (to save some steps and typing), or the other that when you highlight NH number it will popup and preview the doujin (in fear of stepping into degenerated doujin). 
69 | - I was like WTF this is the best you people can think of??? What The Heck??? Why do you people so serious about those little number?? Just copy paste it and go to the site to check it out like a man!!
70 | - Ok I'm done ranting, that was how this extension was born.
71 | 
72 | **Problems, HALP!**
73 | - Report it in Github issue. Thank you!
74 | - Or fix it yourself if you are a wizkid.
75 | 
76 | ### Credit
77 | - To great myself.
78 | - Took code skeleton from https://github.com/Xwilarg/NHentaiAnalytics thanks!
79 | - Stackoverflow for making me able to go through JavaScript hell after not writing it for 5 years. At least it is better than Java shit.

 52 |       or by an individual or Legal Entity authorized to submit on behalf of
 53 |       the copyright owner. For the purposes of this definition, "submitted"
 54 |       means any form of electronic, verbal, or written communication sent

 59 |       excluding communication that is conspicuously marked or otherwise
 60 |       designated in writing by the copyright owner as "Not a Contribution."
 61 | 
 62 |       "Contributor" shall mean Licensor and any individual or Legal Entity

 80 |       Contribution(s) alone or by combination of their Contribution(s)
 81 |       with the Work to which such Contribution(s) was submitted. If You
 82 |       institute patent litigation against any entity (including a
 83 |       cross-claim or counterclaim in a lawsuit) alleging that the Work
 84 |       or a Contribution incorporated within the Work constitutes direct
 85 |       or contributory patent infringement, then any patent licenses
 86 |       granted to You under this License for that Work shall terminate

 93 | 
 94 |       (a) You must give any other recipients of the Work or
 95 |           Derivative Works a copy of this License; and
 96 | 
 97 |       (b) You must cause any modified files to carry prominent notices
 98 |           stating that You changed the files; and
 99 | 
100 |       (c) You must retain, in the Source form of any Derivative Works
101 |           that You distribute, all copyright, patent, trademark, and

103 |           excluding those notices that do not pertain to any part of
104 |           the Derivative Works; and
105 | 
106 |       (d) If the Work includes a "NOTICE" text file as part of its
107 |           distribution, then any Derivative Works that You distribute must
108 |           include a readable copy of the attribution notices contained
109 |           within such NOTICE file, excluding those notices that do not
110 |           pertain to any part of the Derivative Works, in at least one
111 |           of the following places: within a NOTICE text file distributed
112 |           as part of the Derivative Works; within the Source form or
113 |           documentation, if provided along with the Derivative Works; or,
114 |           within a display generated by the Derivative Works, if and
115 |           wherever such third-party notices normally appear. The contents
116 |           of the NOTICE file are for informational purposes only and
117 |           do not modify the License. You may add Your own attribution
118 |           notices within Derivative Works that You distribute, alongside
119 |           or as an addendum to the NOTICE text from the Work, provided
120 |           that such additional attribution notices cannot be construed
121 |           as modifying the License.
122 | 
123 |       You may add Your own copyright statement to Your modifications and
124 |       may provide additional or different license terms and conditions
125 |       for use, reproduction, or distribution of Your modifications, or
126 |       for any such Derivative Works as a whole, provided Your use,
127 |       reproduction, and distribution of the Work otherwise complies with
128 |       the conditions stated in this License.
129 | 
130 |    5. Submission of Contributions. Unless You explicitly state otherwise,
131 |       any Contribution intentionally submitted for inclusion in the Work
132 |       by You to the Licensor shall be under the terms and conditions of
133 |       this License, without any additional terms or conditions.
134 |       Notwithstanding the above, nothing herein shall supersede or modify
135 |       the terms of any separate license agreement you may have executed
136 |       with Licensor regarding such Contributions.
137 | 
138 |    6. Trademarks. This License does not grant permission to use the trade
139 |       names, trademarks, service marks, or product names of the Licensor,
140 |       except as required for reasonable and customary use in describing the
141 |       origin of the Work and reproducing the content of the NOTICE file.
142 | 
143 |    7. Disclaimer of Warranty. Unless required by applicable law or
144 |       agreed to in writing, Licensor provides the Work (and each
145 |       Contributor provides its Contributions) on an "AS IS" BASIS,
146 |       WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
147 |       implied, including, without limitation, any warranties or conditions
148 |       of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
149 |       PARTICULAR PURPOSE. You are solely responsible for determining the
150 |       appropriateness of using or redistributing the Work and assume any
151 |       risks associated with Your exercise of permissions under this License.
152 | 
153 |    8. Limitation of Liability. In no event and under no legal theory,
154 |       whether in tort (including negligence), contract, or otherwise,
155 |       unless required by applicable law (such as deliberate and grossly
156 |       negligent acts) or agreed to in writing, shall any Contributor be
157 |       liable to You for damages, including any direct, indirect, special,
158 |       incidental, or consequential damages of any character arising as a
159 |       result of this License or out of the use or inability to use the
160 |       Work (including but not limited to damages for loss of goodwill,
161 |       work stoppage, computer failure or malfunction, or any and all
162 |       other commercial damages or losses), even if such Contributor
163 |       has been advised of the possibility of such damages.
164 | 
165 |    9. Accepting Warranty or Additional Liability. While redistributing
166 |       the Work or Derivative Works thereof, You may choose to offer,
167 |       and charge a fee for, acceptance of support, warranty, indemnity,
168 |       or other liability obligations and/or rights consistent with this
169 |       License. However, in accepting such obligations, You may act only
170 |       on Your own behalf and on Your sole responsibility, not on behalf
171 |       of any other Contributor, and only if You agree to indemnify,
172 |       defend, and hold each Contributor harmless for any liability
173 |       incurred by, or claims asserted against, such Contributor by reason
174 |       of your accepting any such warranty or additional liability.
