+# Comic Source
+
+## Introduction
+
+Venera is a comic reader that can read comics from various sources. 
+
+All comic sources are written in javascript. 
+Venera uses [flutter_qjs](https://github.com/wgh136/flutter_qjs) as js engine which is forked from [ekibun](https://github.com/ekibun/flutter_qjs).
+
+This document will describe how to write a comic source for Venera.
+
+## Preparation
+
+- Install Venera. Using flutter to run the project is recommended since it's easier to debug.
+- An editor that supports javascript.
+- Download template and venera javascript api from [here](https://github.com/venera-app/venera-configs).
+
+## Start Writing
+
+The template contains detailed comments and examples. You can refer to it when writing your own comic source.
+
+Here is a brief introduction to the template:
+
+> Note: Javascript api document is [here](js_api.md).
+
+### Write basic information
+
+```javascript
+class NewComicSource extends ComicSource {
+    // Note: The fields which are marked as [Optional] should be removed if not used
+
+    // name of the source
+    name = ""
+
+    // unique id of the source
+    key = ""
+
+    version = "1.0.0"
+
+    minAppVersion = "1.0.0"
+
+    // update url
+    url = ""
+// ...
+}
+```
+
+In this part, you need to do the following:
+- Change the class name to your source name.
+- Fill in the name, key, version, minAppVersion, and url fields.
+
+### init function
+
+```javascript
+    /**
+     * [Optional] init function
+     */
+    init() {
+
+    }
+```
+
+The function will be called when the source is initialized. You can do some initialization work here.
+
+Remove this function if not used.
+
+### Account
+
+```javascript
+// [Optional] account related
+    account = {
+        /**
+         * [Optional] login with account and password, return any value to indicate success
+         * @param account {string}
+         * @param pwd {string}
+         * @returns {Promise<any>}
+         */
+        login: async (account, pwd) => {
+
+        },
+
+        /**
+         * [Optional] login with webview
+         */
+        loginWithWebview: {
+            url: "",
+            /**
+             * check login status
+             * @param url {string} - current url
+             * @param title {string} - current title
+             * @returns {boolean} - return true if login success
+             */
+            checkStatus: (url, title) => {
+
+            },
+            /**
+             * [Optional] Callback when login success
+             */
+            onLoginSuccess: () => {
+
+            },
+        },
+
+        /**
+         * [Optional] login with cookies
+         * Note: If `this.account.login` is implemented, this will be ignored
+         */
+        loginWithCookies: {
+            fields: [
+                "ipb_member_id",
+                "ipb_pass_hash",
+                "igneous",
+                "star",
+            ],
+            /**
+             * Validate cookies, return false if cookies are invalid.
+             *
+             * Use `Network.setCookies` to set cookies before validate.
+             * @param values {string[]} - same order as `fields`
+             * @returns {Promise<boolean>}
+             */
+            validate: async (values) => {
+
+            },
+        },
+
+        /**
+         * logout function, clear account related data
+         */
+        logout: () => {
+
+        },
+
+        // {string?} - register url
+        registerWebsite: null
+    }
+```
+
+In this part, you can implement login, logout, and register functions.
+
+Remove this part if not used.
+
+### Explore page
+
+```javascript
+    // explore page list
+    explore = [
+        {
+            // title of the page.
+            // title is used to identify the page, it should be unique
+            title: "",
+
+            /// multiPartPage or multiPageComicList or mixed
+            type: "multiPartPage",
+
+            /**
+             * load function
+             * @param page {number | null} - page number, null for `singlePageWithMultiPart` type
+             * @returns {{}}
+             * - for `multiPartPage` type, return {title: string, comics: Comic[], viewMore: string?}[]
+             * - for `multiPageComicList` type, for each page(1-based), return {comics: Comic[], maxPage: number}
+             * - for `mixed` type, use param `page` as index. for each index(0-based), return {data: [], maxPage: number?}, data is an array contains Comic[] or {title: string, comics: Comic[], viewMore: string?}
+             */
+            load: async (page) => {
+
+            },
+
+            /**
+             * Only use for `multiPageComicList` type.
+             * `loadNext` would be ignored if `load` function is implemented.
+             * @param next {string | null} - next page token, null if first page
+             * @returns {Promise<{comics: Comic[], next: string?}>} - next is null if no next page.
+             */
+            loadNext(next) {},
+        }
+    ]
+```
+
+In this part, you can implement the explore page.
+
+A comic source can have multiple explore pages.
+
+There are three types of explore pages:
+- multiPartPage: An explore page contains multiple parts, each part contains multiple comics.
+- multiPageComicList: An explore page contains multiple comics, the comics are loaded page by page.
+- mixed: An explore page contains multiple parts, each part can be a list of comics or a block of comics which have a title and a view more button.
+
+### Category Page
+
+```javascript
+    // categories
+    category = {
+        /// title of the category page, used to identify the page, it should be unique
+        title: "",
+        parts: [
+            {
+                // title of the part
+                name: "Theme",
+
+                // fixed or random
+                // if random, need to provide `randomNumber` field, which indicates the number of comics to display at the same time
+                type: "fixed",
+
+                // number of comics to display at the same time
+                // randomNumber: 5,
+
+                categories: ["All", "Adventure", "School"],
+
+                // category or search
+                // if `category`, use categoryComics.load to load comics
+                // if `search`, use search.load to load comics
+                itemType: "category",
+
+                // [Optional] {string[]?} must have same length as categories, used to provide loading param for each category
+                categoryParams: ["all", "adventure", "school"],
+
+                // [Optional] {string} cannot be used with `categoryParams`, set all category params to this value
+                groupParam: null,
+            }
+        ],
+        // enable ranking page
+        enableRankingPage: false,
+    }
+```
+
+Category page is a static page that contains multiple parts, each part contains multiple categories.
+
+A comic source can only have one category page.
+
+### Category Comics Page
+
+```javascript
+    /// category comic loading related
+    categoryComics = {
+        /**
+         * load comics of a category
+         * @param category {string} - category name
+         * @param param {string?} - category param
+         * @param options {string[]} - options from optionList
+         * @param page {number} - page number
+         * @returns {Promise<{comics: Comic[], maxPage: number}>}
+         */
+        load: async (category, param, options, page) => {
+
+        },
+        // provide options for category comic loading
+        optionList: [
+            {
+                // For a single option, use `-` to separate the value and text, left for value, right for text
+                options: [
+                    "newToOld-New to Old",
+                    "oldToNew-Old to New"
+                ],
+                // [Optional] {string[]} - show this option only when the value not in the list
+                notShowWhen: null,
+                // [Optional] {string[]} - show this option only when the value in the list
+                showWhen: null
+            }
+        ],
+        ranking: {
+            // For a single option, use `-` to separate the value and text, left for value, right for text
+            options: [
+                "day-Day",
+                "week-Week"
+            ],
+            /**
+             * load ranking comics
+             * @param option {string} - option from optionList
+             * @param page {number} - page number
+             * @returns {Promise<{comics: Comic[], maxPage: number}>}
+             */
+            load: async (option, page) => {
+
+            }
+        }
+    }
+```
+
+When user clicks on a category, the category comics page will be displayed.
+
+This part is used to load comics of a category.
+
+### Search
+
+```javascript
+    /// search related
+    search = {
+        /**
+         * load search result
+         * @param keyword {string}

+         * @returns {Promise<{comics: Comic[], maxPage: number}>}
+         */
+        load: async (keyword, options, page) => {
+
+        },
+
+        /**
+         * load search result with next page token.
+         * The field will be ignored if `load` function is implemented.
+         * @param keyword {string}
+         * @param options {(string)[]} - options from optionList
+         * @param next {string | null}
+         * @returns {Promise<{comics: Comic[], maxPage: number}>}
+         */
+        loadNext: async (keyword, options, next) => {
+
+        },
+
+        // provide options for search
+        optionList: [
+            {
+                // [Optional] default is `select`
+                // type: select, multi-select, dropdown
+                // For select, there is only one selected value
+                // For multi-select, there are multiple selected values or none. The `load` function will receive a json string which is an array of selected values
+                // For dropdown, there is one selected value at most. If no selected value, the `load` function will receive a null
+                type: "select",

+        ],
+
+        // enable tags suggestions
+        enableTagsSuggestions: false,
+    }
+```
+
+This part is used to load search results.
+
+`load` and `loadNext` functions are used to load search results. 
+If `load` function is implemented, `loadNext` function will be ignored.
+
+### Favorites
+
+```javascript

+# Import Comic
+
+## Introduction
+
+Venera supports importing comics from local files.
+However, the comic files must be in a specific format.
+
+## Comic Directory
+
+A directory considered as a comic directory only if it follows one of the following two types of structure:
+
+**Without Chapter**
+
+```
+comic_directory
+├── cover.[ext]
+├── img1.[ext]
+├── img2.[ext]
+├── img3.[ext]
+├── ...
+```
+
+**With Chapter**
+
+```
+comic_directory
+├── cover.[ext]
+├── chapter1
+│   ├── img1.[ext]
+│   ├── img2.[ext]
+│   ├── img3.[ext]
+│   ├── ...
+├── chapter2
+│   ├── img1.[ext]
+│   ├── img2.[ext]
+│   ├── img3.[ext]
+│   ├── ...
+├── ...
+```
+
+The file name can be anything, but the extension must be a valid image extension.
+
+The page order is determined by the file name. App will sort the files by name and display them in that order.
+
+Cover image is optional. 
+If there is a file named `cover.[ext]` in the directory, it will be considered as the cover image.
+Otherwise, the first image will be considered as the cover image.
+
+The name of directory will be used as comic title. And the name of chapter directory will be used as chapter title.
+
+## Archive
+
+Venera supports importing comics from archive files.
+
+The archive file must follow [Comic Book Archive](https://en.wikipedia.org/wiki/Comic_book_archive_file) format.
+
+Currently, Venera supports the following archive formats:
+- `.cbz`
+- `.cb7`
+- `.zip`
+- `.7z`
