If you've found a bug, please create a [new issue](https://github.com/shaarli/Shaarli/issues/new).
6
7If you'd like a feature added, see if it fits in the list of [Ideas for Plugins](Ideas-for-plugins) and update the corresponding bug report.
8
9_Note: This documentation is available online at https://github.com/shaarli/Shaarli/wiki, and locally in the `doc/` directory of your Shaarli installation._
10
11------------------------------------------------------------------
12
13# Basic Usage
14
15### Add the sharing button (_bookmarklet_) to your browser
16
17 * Open your Shaarli and `Login`
18 * Click the `Tools` button in the top bar
19 * Drag the **`✚Shaare link` button**, and drop it to your browser's bookmarks bar.
20
21_This bookmarklet button in compatible with Firefox, Opera, Chrome and Safari. Under Opera, you can't drag'n drop the button: You have to right-click on it and add a bookmark to your personal toolbar._
22
23![](images/bookmarklet.png)
24
25### Share links using the _bookmarklet_
26
27 * When you are visiting a webpage you would like to share with Shaarli, click the _bookmarklet_ you just added.
28 * A window opens.
29 * You can freely edit title, description, tags... to find it later using the text search or tag filtering.
30 * You will be able to edit this link later using the ![](https://raw.githubusercontent.com/shaarli/Shaarli/master/images/edit_icon.png) edit button.
31 * You can also check the “Private” box so that the link is saved but only visible to you.
32 * Click `Save`.**Voila! Your link is now shared.**
33
34
35
36
37# Other usage examples
38Shaarli can be used:
39
40 * to share, comment and save interesting links and news
41 * to bookmark useful/frequent personal links (as private links) and share them between computers
42 * as a minimal blog/microblog/writing platform (no character limit)
43 * as a read-it-later list (for example items tagged `readlater`)
44 * to draft and save articles/ideas
45 * to keep code snippets
46 * to keep notes and documentation
47 * as a shared clipboard between machines
48 * as a todo list
49 * to store playlists (e.g. with the `music` or `video` tags)
50 * to keep extracts/comments from webpages that may disappear
51 * to keep track of ongoing discussions (for example items tagged `discussion`)
52 * [to feed RSS aggregators](http://shaarli.chassegnouf.net/?9Efeiw) (planets) with specific tags
53 * to feed other social networks, blogs... using RSS feeds and external services (dlvr.it, ifttt.com ...)
54
55### Using Shaarli as a blog, notepad, pastebin...
56
57 * Go to your Shaarli setup and log in
58 * Click the `Add Link` button
59 * To share text only, do not enter any URL in the corresponding input field and click `Add Link`
60 * Pick a title and enter your article, or note, in the description field; add a few tags; optionally check `Private` then click `Save`
61 * Voilà! Your article is now published (privately if you selected that option) and accessible using its permalink.
62
63
64### RSS Feeds or Picture Wall for a specific search/tag
65It is possible to filter RSS/ATOM feeds and Picture Wall on a Shaarli to **only display results of a specific search, or for a specific tag**. For example, if you want to subscribe only to links tagged `photography`:
66 * Go to the desired Shaarli instance.
67 * Search for the `photography` tag in the _Filter by tag_ box. Links tagged `photography` are displayed.
68 * Click on the `RSS Feed` button.
69 * You are presented with an RSS feed showing only these links. Subscribe to it to receive only updates with this tag.
70 * The same method **also works for a full-text search** (_Search_ box) **and for the Picture Wall** (want to only see pictures about `nature`?)
71 * You can also build the URL manually: `https://my.shaarli.domain/?do=rss&searchtags=nature`, `https://my.shaarli.domain/links/?do=picwall&searchterm=poney`
72
73![](rss-filter-1.png) ![](rss-filter-2.png)
74
75# Configuration
76
77### Main data/options.php file
78
79To change the configuration, create the file `data/options.php`, example:
80```
81 <?php
82 $GLOBALS['config']['LINKS_PER_PAGE'] = 30;
83 $GLOBALS['config']['HIDE_TIMESTAMPS'] = true;
84 $GLOBALS['config']['ENABLE_THUMBNAILS'] = false;
85 ?>
86```
87 The following parameters are available (parameters (default value)):
88
89 * `DATADIR ('data')` : This is the name of the subdirectory where Shaarli stores is data file. You can change it for better security.
90 * `CONFIG_FILE ($GLOBALS['config']['DATADIR'].'/config.php')` : Name of file which is used to store login/password.
91 * `DATASTORE ($GLOBALS['config']['DATADIR'].'/datastore.php')` : Name of file which contains the link database.
92 * `LINKS_PER_PAGE (20)` : Default number of links per page displayed.
93 * `IPBANS_FILENAME ($GLOBALS['config']['DATADIR'].'/ipbans.php')` : Name of file which records login attempts and IP bans.
94 * `BAN_AFTER (4)` : An IP address will be banned after this many failed login attempts.
95 * `BAN_DURATION (1800)` : Duration of ban (in seconds). (1800 seconds = 30 minutes)
96 * `OPEN_SHAARLI (false)` : If you set this option to true, anyone will be able to add/modify/delete/import/exports links without having to login.
97 * `HIDE_TIMESTAMPS (false)` : If you set this option to true, the date/time of each link will not be displayed (including in RSS Feed).
98 * `ENABLE_THUMBNAILS (true)` : Enable/disable thumbnails.
99 * `CACHEDIR ('cache')` : Directory where the thumbnails are stored.
100 * `ENABLE_LOCALCACHE (true)` : If you have a limited quota on your webspace, you can set this option to false: Shaarli will not generate thumbnails which need to be cached locally (vimeo, flickr, etc.). Thumbnails will still be visible for the services which do not use the local cache (youtube.com, imgur.com, dailymotion.com, imageshack.us)
101 * `UPDATECHECK_FILENAME ($GLOBALS['config']['DATADIR'].'/lastupdatecheck.txt')` : name of the file used to store available shaarli version.
102 * `UPDATECHECK_INTERVAL (86400)` : Delay between new Shaarli version check. 86400 seconds = 24 hours. Note that if you do not login for a week, Shaarli will not check for new version for a week.
103 * `ENABLE_UPDATECHECK`: Determines whether Shaarli check for new releases at https://github.com/shaarli/Shaarli
104 * `SHOW_ATOM (false)` : Show an `ATOM Feed` button next to the `Subscribe` (RSS) button. ATOM feeds are available at the address `?do=atom` regardless of this option.
105 * `ARCHIVE_ORG (false)` : For each link, display a link to an archived version on archive.org
106 * `ENABLE_RSS_PERMALINKS (true)`: choose whether the RSS item title link points directly to the link, or to the entry on Shaarli (permalink). `true` is the original Shaarli bahevior (point directly to the link)
107
108
109### Changing theme
110 * Shaarli's apparence can be modified by editing CSS rules in `inc/user.css`. This file allows to override rules defined in the main `inc/shaarli.css` (only add changed rules), or define a whole new theme.
111 * Do not edit `inc/shaarli.css`! Your changes would be overriden when updating Shaarli.
112 * Some themes are available at https://github.com/shaarli/shaarli-themes.
113
114See also:
115 * [Download CSS styles for shaarlis listed in an opml file](https://github.com/shaarli/Shaarli/wiki/Download-CSS-styles-for-shaarlis-listed-in-an-opml-file)
116
117
118# Backup
119
120You have two ways of backing up your database:
121* **Backup the file `data/datastore.php`** (by FTP or SSH). Restore by putting the file back in place.
122 * Example command: `rsync -avzP my.server.com:/var/www/shaarli/data/datastore.php datastore-$(date +%Y-%m-%d_%H%M).php`
123* **Export your links as HTML** (Menu `Tools` > `Export`). Restore by using the `Import` feature.
124 * This can be done using the [shaarchiver](https://github.com/nodiscc/shaarchiver) tool. Example command: `./export-bookmarks.py --url=https://my.server.com/shaarli --username=myusername --password=mysupersecretpassword --download-dir=./ --type=all`
125
126
127
128# Login bruteforce protection
129Login form is protected against brute force attacks: 4 failed logins will ban the IP address from login for 30 minutes. Banned IPs can still browse links.
130
131To remove the current IP bans, delete the file `data/ipbans.php`
132
133## List of all login attempts
134
135The file `data/log.txt` shows all logins (successful or failed) and bans/lifted bans.
136Search for `failed` in this file to look for unauthorized login attempts.
137
138# Troubleshooting
139
140### I forgot my password !
141
142Delete the file data/config.php and display the page again. You will be asked for a new login/password.
143
144
145### Exporting from Diigo
146
147If you export your bookmark from Diigo, make sure you use the Delicious export, not the Netscape export. (Their Netscape export is broken, and they don't seem to be interested in fixing it.)
148
149### Importing from SemanticScuttle
150
151To correctly import the tags from a [SemanticScuttle](http://semanticscuttle.sourceforge.net/) HTML export, edit the HTML file before importing and replace all occurences of `tags=` (lowercase) to `TAGS=` (uppercase).
152
153### Importing from Mister Wong
154See [this issue](https://github.com/sebsauvage/Shaarli/issues/146) for import tweaks.
155
156
157### Hosting problems
158 * On **free.fr** : Please note that free uses php 5.1 and thus you will not have autocomplete in tag editing. Don't forget to create a `sessions` directory at the root of your webspace. Change the file extension to `.php5` or create a `.htaccess` file in the directory where Shaarli is located containing:
159
160```
161php 1
162SetEnv PHP_VER 5
163```
164
165 * If you have an error such as: `Parse error: syntax error, unexpected '=', expecting '(' in /links/index.php on line xxx`, it means that your host is using php4, not php5. Shaarli requires php 5.1. Try changing the file extension to `.php5`
166 * On **1and1** : If you add the link from the page (and not from the bookmarklet), Shaarli will no be able to get the title of the page. You will have to enter it manually. (Because they have disabled the ability to download a file through HTTP).
167 * If you have the error `Warning: file_get_contents() [function.file-get-contents]: URL file-access is disabled in the server configuration in /…/index.php on line xxx`, it means that your host has disabled the ability to fetch a file by HTTP in the php config (Typically in 1and1 hosting). Bad host. Change host. Or comment the following lines:
168
169```
170//list($status,$headers,$data) = getHTTP($url,4); // Short timeout to keep the application responsive.
171// FIXME: Decode charset according to charset specified in either 1) HTTP response headers or 2) <head> in html
172//if (strpos($status,'200 OK')) $title=html_extract_title($data);
173```
174
175 * On hosts which forbid outgoing HTTP requests (such as free.fr), some thumbnails will not work.
176 * On **lost-oasis**, RSS doesn't work correctly, because of this message at the begining of the RSS/ATOM feed : `<? // tout ce qui est charge ici (generalement des includes et require) est charge en permanence. ?>`. To fix this, remove this message from `php-include/prepend.php`
177
178### Dates are not properly formatted
179Shaarli tries to sniff the language of the browser (using HTTP_ACCEPT_LANGUAGE headers) and choose a date format accordingly. But Shaarli can only use the date formats (and more generaly speaking, the locales) provided by the webserver. So even if you have a browser in French, you may end up with dates in US format (it's the case on sebsauvage.net :-( )
180
181### Problems on CentOS servers
182On **CentOS**/RedHat derivatives, you may need to install the `php-mbstring` package.
183
184
185### My session expires ! I can't stay logged in
186This can be caused by several things:
187
188* Your php installation may not have a proper directory setup for session files. (eg. on Free.fr you need to create a `session` directory on the root of your website.) You may need to create the session directory of set it up.
189* Most hosts regularly clean the temporary and session directories. Your host may be cleaning those directories too aggressively (eg.OVH hosts), forcing an expire of the session. You may want to set the session directory in your web root. (eg. Create the `sessions` subdirectory and add `ini_set('session.save_path', $_SERVER['DOCUMENT_ROOT'].'/../sessions');`. Make sure this directory is not browsable !)
190* If your IP address changes during surfing, Shaarli will force expire your session for security reasons (to prevent session cookie hijacking). This can happen when surfing from WiFi or 3G (you may have switched WiFi/3G access point), or in some corporate/university proxies which use load balancing (and may have proxies with several external IP addresses).
191* Some browser addons may interfer with HTTP headers (ipfuck/ipflood/GreaseMonkey…). Try disabling those.
192* You may be using OperaTurbo or OperaMini, which use their own proxies which may change from time to time.
193* If you have another application on the same webserver where Shaarli is installed, these application may forcefully expire php sessions.
194
195### `Sessions do not seem to work correctly on your server`
196Follow the instructions in the error message. Make sure you are accessing shaarli via a direct IP address or a proper hostname. If you have **no dots** in the hostname (e.g. `localhost` or `http://my-webserver/shaarli/`), some browsers will not store cookies at all (this respects the [HTTP cookie specification](http://curl.haxx.se/rfc/cookie_spec.html)).
197
198
199### pubsubhubbub support
200
201Download [publisher.php](https://pubsubhubbub.googlecode.com/git/publisher_clients/php/library/publisher.php) at the root of your Shaarli installation and set `$GLOBALS['config']['PUBSUBHUB_URL']` in your `config.php`
202
203# Notes
204### Various hacks
205
206 * [Example patch: add a new "via" field for links](Example-patch---add-new-via-field-for-links)
207 * [Copy a Shaarli installation over SSH SCP, serve it locally with php cli](Copy-a-Shaarli-installation-over-SSH-SCP,-serve-it-locally-with-php-cli)
208 * To display the array representing the data saved in datastore.php, use the following snippet
209
210### Changing timestamp for a link
211 * Look for `<input type="hidden" name="lf_linkdate" value="{$link.linkdate}">` in `tpl/editlink.tpl` (line 14)
212 * Remove `type="hidden"` from this line
213 * A new date/time field becomes available in the edit/new link dialog. You can set the timestamp manually by entering it in the format `YYYMMDD_HHMMS`.
214
215```
216$data = "tZNdb9MwFIb... <Commented content inside datastore.php>";
217$out = unserialize(gzinflate(base64_decode($data)));
218echo "<pre>"; // Pretty printing is love, pretty printing is life
219print_r($out);
220echo "</pre>";
221exit;
222```
223This will output the internal representation of the datastore, "unobfuscated" (if this can really be considered obfuscation)

264# FAQ
265
266### Why did you create Shaarli ?
267
268I was a StumbleUpon user. Then I got fed up with they big toolbar. I switched to delicious, which was lighter, faster and more beautiful. Until Yahoo bought it. Then the export API broke all the time, delicious became slow and was ditched by Yahoo. I switched to Diigo, which is not bad, but does too much. And Diigo is sslllooooowww and their Firefox extension a bit buggy. And… oh… **their Firefox addon sends to Diigo every single URL you visit** (Don't believe me ? Use [Tamper Data](https://addons.mozilla.org/en-US/firefox/addon/tamper-data/) and open any page).
269
270Enough is enough. Saving simple links should not be a complicated heavy thing. I ditched them all and wrote my own: Shaarli. It's simple, but it does the job and does it well. And my data is not hosted on a foreign server, but on my server.
271
272### Why use Shaarli and not Delicious/Diigo ?
273
274With Shaarli:
275
276* The data is yours: It's hosted on your server.
277* Never fear of having your data locked-in.
278* Never fear to have your data sold to third party.
279* Your private links are not hosted on a third party server.
280* You are not tracked by browser addons (like Diigo does)
281* You can change the look and feel of the pages if you want.
282* You can change the behaviour of the program.
283* It's magnitude faster than most bookmarking services.
284
285### What does Shaarli mean ?
286
287Shaarli is for shaaring your links.
288
289
290
291# Technical details
292 * Application is protected against XSRF (Cross-site requests forgery): Forms which act on data (save,delete…) contain a token generated by the server. Any posted form which does not contain a valid token is rejected. Any token can only be used once. Token are attached to the session and cannot be reused in another session.
293 * Sessions automatically expires after 60 minutes. Sessions are protected against highjacking: The sessionID cannot be used from a different IP address.
294 * An .htaccess file protects the data file.
295 * Link database is an associative array which is serialized, compressed (with deflate), base64-encoded and saved as a comment in a .php file. Thus even if the server does not support htaccess files, the data file will still not be readable by URL. The database looks like this:
296```
297<?php /* zP1ZjxxJtiYIvvevEPJ2lDOaLrZv7o...
298...ka7gaco/Z+TFXM2i7BlfMf8qxpaSSYfKlvqv/x8= */ ?>
299```
300
301* The password is salted, hashed and stored in the data subdirectory, in a php file, and protected by htaccess. Even if the webserver does not support htaccess, the hash is not readable by URL. Even if the .php file is stolen, the password cannot deduced from the hash. The salt prevents rainbow-tables attacks.
302* Shaarli relies on `HTTP_REFERER` for some functions (like redirects and clicking on tags). If you have disabled or masqueraded `HTTP_REFERER` in your browser, some features of Shaarli may not work
303* `magic_quotes` is a horrible option of php which is often activated on servers. No serious developer should rely on this horror to secure their code against SQL injections. You should disable it (and Shaarli expects this option to be disabled). Nevertheless, I have added code to cope with magic_quotes on, so you should not be bothered even on crappy hosts.
304* Small hashes are used to make a link to an entry in Shaarli. They are unique. In fact, the date of the items (eg.20110923_150523) is hashed with CRC32, then converted to base64 and some characters are replaced. They are always 6 characters longs and use only A-Z a-z 0-9 - _ and @.
305
306### Directory structure

322 data/ : Directory where data is stored (bookmark database, configuration, logs, banlist…)
323 config.php : Shaarli configuration (login, password, timezone, title…)
324 datastore.php : Your link database (compressed).
325 ipban.php : IP address ban system data.
326 lastupdatecheck.txt : Update check timestamp file (used to check every 24 hours if a new version of Shaarli is available).
327 log.txt : login/IPban log.

332### Why not use a real database ? Files are slow !
333
334Does browsing [this page](http://sebsauvage.net/links/) feel slow ? Try browsing older pages, too.

336It's not slow at all, is it ? And don't forget the database contains more than 16000 links, and it's on a shared host, with 32000 visitors/day for my website alone. And it's still damn fast. Why ?

338The data file is only 3.7 Mb. It's read 99% of the time, and is probably already in the operation system disk cache. So generating a page involves no I/O at all most of the time.
