This means that if someone sends you a pdf over Slack or if you move a file to the PaperMemoryStore folder for instance, you won't be able to match it to a PaperMemory item. - -## FAQ - -
-Why does PaperMemory require access to all urls? -
-Because Chrome & Brave will disable an extension by default when it auto-updates with new permissions. In this case, any new addition of a paper source will require new permissions to access the data necessary to parse the paper data and will therefore disable the extension until users re-enable it. -
+My approach with PaperMemory is to try and notify you that a publication likely exists by utilizing the `note` field. You will occasionally notice `Accepted @ X` in a Paper's notes. This will be added automatically if you are on a known published venue's website (as Nature, PMLR or NeurIPS) but also from DBLB, CrossRef.org, SemanticScholar.org or Google Scholar. -
-The button to go from an abstract to its pdf does not work -
-In general there can be 2 reasons: - -1. It's a bug, it can happen, I'm sorry about this: you should raise an issue, and ideally even provide a fix in a Pull Resquest -2. More likely, the pdf is behind a paywall and the standard `abstract -> pdf` path was redirected by the venue's website - -

- -
-Where does PaperMemory store my data? -
-It's all stored locally in your browser's local storage. If you want to transfer data to a new browser/computer, use the export/import tools in the extension's options. -
- -
-How can I export all or some papers? -
- -In the Advanced Options page, you can either export your full memory data to a .json or .bib bibliography, or only export papers with a given tag. More details in #89 -
- -
-How do I resolve duplicates? -
- - -
- -
-Can I access the memory full-screen? -
-Sure! In the extension popup's menu, there's a link at the bottom to the full-page memory. You can also just go to this url (Thanks @kaixin96!): - -``` -chrome-extension://ehchlpggdaffcncbeopdopnndhdjelbc/src/fullMemory/fullMemory.html -``` -
- -
-Can I exclude a paper source? -
-Yep. In the extension popup's advanced options page: right-click the extension's icon and click on `Options`. Or click on the link at the bottom of the popup menu. Or go to this url (Thanks @kaixin96!): - -``` -chrome-extension://ehchlpggdaffcncbeopdopnndhdjelbc/src/options/options.html -``` -

-Are there data backups? -
+## Discovering Code repositories -In case there's a bad bug or you mess up when overwriting your memory, PaperMemory preforms weekly backups (locally as always), which you can retrieve with a little coding: +PaperMemory uses the PapersWithCode API in order to discover code repositories 🖥️ -1. Open the extension's options (either right clicking its icon, or from the extension's menu, at the bottom) -2. On the options page, open the Javascript Console with `cmd/ctrl + alt + i` or `right click > Inspect` -3. Do the following in the Javascript Console: - ```javascript - const backups = await getStorage("weeklyBackups") - console.log(Object.keys(backups)) // this shows you available backup dates - const overwrite = backups[""] - console.log(overwrite) // inspect this and make sure it is what you want - setStorage("papers", overwrite) // Careful! This will overwrite the current data with the backup data - ``` - Note that if you uninstall PaperMemory all your data will be gone and the only way to keep track of what was in your Memory is to export it first (in the advanced options page). -

In this case, any new addition of a paper source will require new permissions to access the data necessary to parse the paper data and will therefore disable the extension until users re-enable it. + +### The button to go from an abstract to its pdf does not work + +In general there can be 2 reasons: + +1. It's a bug, it can happen, I'm sorry about this: you should raise an issue, and ideally even provide a fix in a Pull Resquest +2. More likely, the pdf is behind a paywall and the standard `abstract -> pdf` path was redirected by the venue's website + + +### How do you match Arxiv.org pre-prints to actual publications? + + +It's all there: [preprints](features.md#preprint-matching) 😃 + +Contributions and ideas on how to improve the process and potentially add publication sources from titles or arxiv `id` are welcome! + +### Where does PaperMemory store my data? + +It's all stored locally in your browser's local storage. If you want to transfer data to a new browser/computer, use the export/import tools in the extension's options. + +### How can I export all or some papers? + +Check out the [Advanced Options](./configuration.md#advanced-options)'s *Data Management* section, you can export: + +* your full PaperMemory data as `.json` file +* your full bibliography as `.bib` file (or `.json`) +* papers based on the tags you'be assigned them as a `.bib` file + +### Can I reference my PDF in PaperMemory? + +If you want to associate a PDF file to a paper in your PaperMemoryStore that is not downloaded from PaperMemory (for instance, it is behind a paywall), you can **download it to `~/Downloads/PaperMemoryStore/`** (maybe you're reading the paper on Sci-Hub you thief 🙃) provided the file's name contains the **paper's title** (not counting non-alphanumeric characters and case-insensitive). + +Because of limitations Browser Extensions face, a file **must** be _downloaded from the Browser to the folder_ in order to be detected. This means that if someone sends you a pdf over Slack or if you move a file to the PaperMemoryStore folder for instance, you won't be able to match it to a PaperMemory item. + +### How do I resolve duplicates? + +* If you installed PaperMemory `<0.5.3` (May 2022) you may have duplicate papers in your Memory. The easiest way to resolve this is to go to a duplicate's page, then delete it from memory and refresh the page. The automatic de-duplication features in version `0.5.3` should handle the matching _if_ the 2 papers have the same title. +* If you still see duplicates with PaperMemory `>=0.5.3` _and_ the 2 papers have the same title, this may be a problem with PaperMemory and you should open an issue here on Github. + + +### Can I access the memory full-screen? + +Sure! In the extension popup's menu, there's a link at the bottom to the full-page memory. You can also just go to this url (Thanks @kaixin96!): + +```bash +# Copy-paste this url (Chrome / Brave / Edge): +chrome-extension://ehchlpggdaffcncbeopdopnndhdjelbc/src/fullMemory/fullMemory.html +# Firefox: +moz-extension://05b6ef8a-7314-4c1d-a519-80f48a5794a6/src/fullMemory/fullMemory.html +``` + +### Can I exclude a paper source? + +Yep. In the extension popup's advanced options page: right-click the extension's icon and click on `Options`. Or click on the link at the bottom of the popup menu. Or go to this url (Thanks @kaixin96!): + +```bash +# Copy-paste this url (Chrome / Brave / Edge): +chrome-extension://ehchlpggdaffcncbeopdopnndhdjelbc/src/options/options.html +# Firefox: +moz-extension://05b6ef8a-7314-4c1d-a519-80f48a5794a6/src/options/options.html +``` + +### Are there data backups? + +In case there's a bad bug or you mess up when overwriting your memory, PaperMemory preforms weekly backups (locally as always), which you can retrieve with a little coding: + +1. Open the extension's options (either right clicking its icon, or from the extension's menu, at the bottom) +2. On the options page, open the Javascript Console with `cmd/ctrl + alt + i` or `right click > Inspect` +3. Do the following in the Javascript Console: + +```javascript +const backups = await getStorage("weeklyBackups") +console.log(Object.keys(backups)) // this shows you available backup dates +const overwrite = backups[""] +console.log(overwrite) // inspect this and make sure it is what you want +setStorage("papers", overwrite) // Careful! This will overwrite the current data with the backup data +``` + +Note that if you uninstall PaperMemory all your data will be gone and the only way to keep track of what was in your Memory is to export it first (in the advanced options page). \ No newline at end of file diff --git a/docs/features.md b/docs/features.md new file mode 100644 index 00000000..dc0190c1 --- /dev/null +++ b/docs/features.md @@ -0,0 +1,288 @@ +--- +description: "PaperMemory's core features: illustrations and explanations." +--- + +# Features + +## User Guides + +

+ +## Memory: Parsing papers + +### Venues + +In order to parse papers from the websites you visit, PaperMemory contains a custom function for each individual paper provider (ArXiv, ScienceDirect, OpenReview, Nature, Science, FrontiersIn, etc.). + +

+Whenever possible, PaperMemory queries the API the provider offers. If they don't offer an open and free API, PaperMemory will parse the page's `HTML` code. When on a PDF's page, PaperMemory contains an URL reversal process to go from PDF to Abstract page. If that cannot be infered from the URL because of the paper provider's URL scheme, there's nothing PaperMemory can do and the PDF will not be stored.(1) +

This makes it really hard to try and implement best practices in terms of citing published papers rather than their preprint. + +My approach with PaperMemory is to try and notify you that a publication likely exists by utilizing the `note` field. You will occasionally notice `Accepted @ X` in a Paper's notes.

+ +* PaperMemory can *only access folders in your Downloads* so the storage *has* to happen there +* It relies on **title matching** to 1/ Open a local file from the Memory 2/ Detect if a currently open file is a known paper to display the Popup. Make sure to have the title in your custom title function. +* If you move files or rename them altering the titles they may not be detected anymore (1). + +
+ +1. PaperMemory primarily relies on `file.finalUrl` to detect if a file corresponds to a known paper. If, for some reason this were to fail, the secondary matching strategy relies on said file name / paper title string matching. + +## Online Synchronization + +![Sync screenshot](assets/sync.png){ align=right .demo-gif } + +Your data can be synced online to be safe-guarded or shared across devices using [Github Gists](https://docs.github.com/en/get-started/writing-on-github/editing-and-sharing-content-with-gists/creating-gists#about-gists). + +This means your data gets written as a commit to a Gist on your Github account, and Papers added to your memory will be saved there.

It\n * might be for example a function that you passed to Observable's constructor, but most of the time it is\n * a library implementation, which defines what will be emitted by an Observable, and when it be will emitted. This means\n * that calling `subscribe` is actually the moment when Observable starts its work, not when it is created, as it is often\n * the thought.\n *\n * Apart from starting the execution of an Observable, this method allows you to listen for values\n * that an Observable emits, as well as for when it completes or errors. You can achieve this in two\n * of the following ways.\n *\n * The first way is creating an object that implements {@link Observer} interface. It should have methods\n * defined by that interface, but note that it should be just a regular JavaScript object, which you can create\n * yourself in any way you want (ES6 class, classic function constructor, object literal etc.). In particular, do\n * not attempt to use any RxJS implementation details to create Observers - you don't need them. Remember also\n * that your object does not have to implement all methods. If you find yourself creating a method that doesn't\n * do anything, you can simply omit it. Note however, if the `error` method is not provided and an error happens,\n * it will be thrown asynchronously. Errors thrown asynchronously cannot be caught using `try`/`catch`. Instead,\n * use the {@link onUnhandledError} configuration option or use a runtime handler (like `window.onerror` or\n * `process.on('error)`) to be notified of unhandled errors. Because of this, it's recommended that you provide\n * an `error` method to avoid missing thrown errors.\n *\n * The second way is to give up on Observer object altogether and simply provide callback functions in place of its methods.\n * This means you can provide three functions as arguments to `subscribe`, where the first function is equivalent\n * of a `next` method, the second of an `error` method and the third of a `complete` method. Just as in case of an Observer,\n * if you do not need to listen for something, you can omit a function by passing `undefined` or `null`,\n * since `subscribe` recognizes these functions by where they were placed in function call. When it comes\n * to the `error` function, as with an Observer, if not provided, errors emitted by an Observable will be thrown asynchronously.\n *\n * You can, however, subscribe with no parameters at all. This may be the case where you're not interested in terminal events\n * and you also handled emissions internally by using operators (e.g. using `tap`).\n *\n * Whichever style of calling `subscribe` you use, in both cases it returns a Subscription object.\n * This object allows you to call `unsubscribe` on it, which in turn will stop the work that an Observable does and will clean\n * up all resources that an Observable used. Note that cancelling a subscription will not call `complete` callback\n * provided to `subscribe` function, which is reserved for a regular completion signal that comes from an Observable.\n *\n * Remember that callbacks provided to `subscribe` are not guaranteed to be called asynchronously.\n * It is an Observable itself that decides when these functions will be called. For example {@link of}\n * by default emits all its values synchronously. Always check documentation for how given Observable\n * will behave when subscribed and if its default behavior can be modified with a `scheduler`.\n *\n * #### Examples\n *\n * Subscribe with an {@link guide/observer Observer}\n *\n * ```ts\n * import { of } from 'rxjs';\n *\n * const sumObserver = {\n * sum: 0,\n * next(value) {\n * console.log('Adding: ' + value);\n * this.sum = this.sum + value;\n * },\n * error() {\n * // We actually could just remove this method,\n * // since we do not really care about errors right now.\n * },\n * complete() {\n * console.log('Sum equals: ' + this.sum);\n * }\n * };\n *\n * of(1, 2, 3) // Synchronously emits 1, 2, 3 and then completes.\n * .subscribe(sumObserver);\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Subscribe with functions ({@link deprecations/subscribe-arguments deprecated})\n *\n * ```ts\n * import { of } from 'rxjs'\n *\n * let sum = 0;\n *\n * of(1, 2, 3).subscribe(\n * value => {\n * console.log('Adding: ' + value);\n * sum = sum + value;\n * },\n * undefined,\n * () => console.log('Sum equals: ' + sum)\n * );\n *\n * // Logs:\n * // 'Adding: 1'\n * // 'Adding: 2'\n * // 'Adding: 3'\n * // 'Sum equals: 6'\n * ```\n *\n * Cancel a subscription\n *\n * ```ts\n * import { interval } from 'rxjs';\n *\n * const subscription = interval(1000).subscribe({\n * next(num) {\n * console.log(num)\n * },\n * complete() {\n * // Will not be called, even when cancelling subscription.\n * console.log('completed!');\n * }\n * });\n *\n * setTimeout(() => {\n * subscription.unsubscribe();\n * console.log('unsubscribed!');\n * }, 2500);\n *\n * // Logs:\n * // 0 after 1s\n * // 1 after 2s\n * // 'unsubscribed!' after 2.5s\n * ```\n *\n * @param {Observer|Function} observerOrNext (optional) Either an observer with methods to be called,\n * or the first of three possible handlers, which is the handler for each value emitted from the subscribed\n * Observable.\n * @param {Function} error (optional) A handler for a terminal event resulting from an error.
