5 Once you have XWiki [[installed>>Documentation.AdminGuide.Installation.WebHome]] you'll want to configure it. Configuration can be done in 2 ways:
6
7 * by stopping the XWiki instance and editing either the ##xwiki/WEB-INF/xwiki.cfg## file or the ##xwiki/WEB-INF/xwiki.properties## one, and then restarting XWiki. Note that ##xwiki.cfg## was the historical file containing the configuration option but we're moving away from it and in due time all the XWiki configuration options will be found in ##xwiki.properties##
8 * by logging in as a user with admin rights and going to the administration page using the top level menu. You can also go directly to //{{{http://localhost:8080/xwiki/bin/admin/XWiki/XWikiPreferences}}}//. This allows to keep the server running while making the changes.(((
9 {{info}}
10 * Some configurations are only accessible from the ##xwiki.cfg## and ##xwiki.properties## files and have no equivalent on the administration page.
11 * If you're a developer and need to understand how Configuration works in XWiki, check the [[Configuration Module Documentation>>extensions:Extension.Configuration Module]].
12 {{/info}}
13 )))You can verify some basic settings of your XWiki installation (on Tomcat, MySQL) using the [[Check Config and Indexes application>>extensions:Extension.Check Config And Indexes Application]].
14
15 There are various things you can configure:
16
17 = Enable superadmin account =
18
19 Edit the ##xwiki.cfg## file and enable the ##xwiki.superadminpassword## property. For example:
20
21 {{code language="none"}}
22 # Enable to allow superadmin. It is disabled by default as this could be a security breach if
23 # it were set and you forgot about it.
24 xwiki.superadminpassword=system
25 {{/code}}
26
27 When logging in, the username will be "superadmin" and the password will be the one you set in the ##xwiki.superadminpassword## property.
28
29 = Language settings =
30
31 To define the default language for your wiki go to the administration page, click on "Localization", locate the "Default Language" field and enter the language code for the language you wish to use. For example: "en" for English, "fr" for French, "de" for German, etc.
32
33 In addition you can configure your wiki to be multilingual. See the [[I18 user page>>platform:Features.I18N]] for more information.
34
35 Last, you can also force your wiki to display only in one of the languages specified in the settings, by editing your ##WEB-INF/xwiki.cfg## file. Search for the "Internationalization" section, and you should see two commented settings that you can uncomment to fix their value (1 means true, 0 false).
36
37 {{code language="none"}}
38 #-# By default, XWiki chooses the language specified by the client (browser) in the Accept-Language HTTP header. This
39 #-# allows to use the default language of the wiki when the user didn't manually choose a language.
40 # xwiki.language.preferDefault=0
41
42 #-# Force only one of the supported languages to be accepted. Default is true.
43 # xwiki.language.forceSupported=1
44 {{/code}}
45
46 {{warning}}
47 Starting with XWiki {{info}}11.2RC1{{/info}} the option ##xwiki.language.forceSupported## is by default set to true. The option was by default set to false on prior versions.
48 {{/warning}}
49
50 = Date format =
51
52 To define the date format used in the interfaces, go to //Wiki -> Administer Wiki -> Localization//, locate the "Date format" field and enter the date format you wish to use. Examples:
53
54 |=Format|=Result
55 |MMMM dd, HH:mm|January 27, 12:27
56 |yyyy/MM/dd, HH:mm|2009/01/27, 12:27
57 |dd/MM/yyyy, HH:mm|27/01/2009, 12:27
58
59 [[More information about date formatting>>http://docs.oracle.com/javase/1.5.0/docs/api/java/text/SimpleDateFormat.html]].
60
61 = Enabling/Disabling Statistics =
62
63 To disable [[the Statistics feature>>extensions:Extension.Statistics Application]] edit your //xwiki.cfg// file and replace the following properties as shown here (to enable statistics, change ##0## to ##1##):
64
65 {{code}}
66 xwiki.stats=0
67 xwiki.stats.default=0
68 {{/code}}
69
70 where:
71
72 * ##xwiki.stats## controls whether statistics are on or off
73 * ##xwiki.stats.default## controls whether statistics are on or off by default for the current Wiki. This is useful in [[Virtual Wiki mode>>Documentation.AdminGuide.Virtualization.WebHome]]. A wiki can decide whether statistics are on or off by setting the "statistics" field in ##XWiki.XWikiPreferences##. If no such field is defined then the default value //xwiki.stats.default// is used.(((
74 {{info}}
75 There's currently no UI to set the statistics on or off for a given subwiki. Thus at the moment you'll need to do 2 things:
76 * Edit ##XWiki.XWikiPreferences## to add a new boolean property to the class, by going to //{{{http://localhost:8080/xwiki/bin/edit/XWiki/XWikiPreferences?editor=class}}}//
77 * Set the ##statistics## property to true by going to //{{{http://localhost:8080/xwiki/bin/edit/XWiki/XWikiPreferences?editor=object}}}// and setting the ##statistics## property to ##true##
78 {{/info}}
79 )))
80
81 = Optional Store Features =
82
83 == Document versioning ==
84
85 One of the key features of a wiki engine is the ability to keep all the history of a document, giving users the ability to see the evolution of a document, but also to revert changes. However, the history of an active wiki continuously grows and is usually much larger than the current version of the data. It is possible to disable the versioning feature in XWiki, which means that less storage space will be used, although it will not be possible to revert the document in case of vandalism.
86
87 To disable versioning edit //xwiki.cfg// and add {{code}}xwiki.store.versioning=0{{/code}}.
88
89 [[Attachment versioning>>Documentation.AdminGuide.Attachments#HVersions]] is also available and turned on by default.
90
91 == Document recycle bin ==
92
93 By default deleted documents are not permanently removed, but are placed in a //recycle bin//, from which they can later be removed or restored. To disable it, edit //xwiki.cfg// and add {{code}}xwiki.recyclebin=0{{/code}}.
94
95 {{info}}
96 Disabling the recycle bin will make it impossible to restore a deleted document, unless a database backup is available.
97 {{/info}}
98
99 By default, a deleted document can be permanently deleted right away by administrators, and after 7 days by regular users. To change these limits, edit //xwiki.cfg// and add:
100
101 {{code}}
102 # Admins must wait 3 days before being allowed to permanently delete
103 xwiki.store.recyclebin.adminWaitDays=3
104 # Normal users must also wait 3 days
105 xwiki.store.recyclebin.waitDays=3
106 {{/code}}
107
108 [[Attachment recycle bin>>Documentation.AdminGuide.Attachments#HDeletion]] is similar.
109
110 = Customizing error pages =
111
112 The screen displayed to the user when an error occurs can be easily customized without modifying the skin in the following cases: when the wiki, document or attachment that is currently looked for does not exist, or when a denied access occurs. You simply need to create the following respective pages in your wiki:
113
114 * ##XWiki.WikiDoesNotExist##,
115 * ##XWiki.DocumentDoesNotExist##,
116 * ##XWiki.AttachmentDoesNotExist##,
117 * ##XWiki.AccessDenied##
118
119 Creating these pages rather than editing the skin's velocity files will save you time during upgrades since you won't need to merge the possibly updated skin files with yours.
120
121 = Customizing the Skin =
122
123 See the [[Skin Guide>>Documentation.AdminGuide.Skins]].
124
125 = Security configuration =
126
127 See the [[Security Guide>>Documentation.AdminGuide.Security]].
128
129 By default the protocol to use to generate external URLs (https, http) is extracted from request to XWiki so most of the time you don't have anything to do if you properly configured your proxy but it's possible to force a specific protocol using ##xwiki.url.protocol## property in //xwiki.cfg//.
130
131 = Customizing Menus =
132
133 The first thing to understand is that menus depend on the skin you're using. If you're using the 1.0 skin it's likely you're using the [[Panels Application>>extensions:Extension.Panels Application]] to provide the different menu panels you see on the left or right of your wikis. Check the [[Panels Application>>extensions:Extension.Panels Application]] to know more on how to configure/modify them.
134
135 = Encoding =
136
137 See the [[Encoding Guide>>Documentation.AdminGuide.Configuration.Encoding.WebHome]].
138
139 = User Authentication =
140
141 See the [[Authentication Guide>>Documentation.AdminGuide.Authentication.WebHome]].
142
143 == Customizing the Verified Registration Page (Since 2.2M2) ==
144
145 The Verified Registration Page is part of the [[Administration Application>>extensions:Extension.Administration Application]] and allows you to require users to fill in a captcha and validates user input on both the server side and the client side using Javascript. The configuration allows you to add fields and validation constraints to the fields which are there.
146
147 Since version 2.3M1 in order to turn on captcha you simply go to the administration page, click "Registration" and you will find a checkbox for turning on captcha along with other registation page related settings.
148
149 For more information about configuring the registration page you can visit the page on the [[Administration Application>>extensions:Extension.Administration Application]].
150
151 = Initial Groups =
152
153 You can set the default groups which new users will automatically be added to by changing the ##xwiki.users.initialGroups## parameter in your [[xwiki.cfg>>Documentation.AdminGuide.Configuration#HSamplexwiki.cfg]] file. To make all new users be added to the groups **XWiki.CoolPeople** and **XWiki.CommunityMembers** you will have to set the ##initialGroups## parameter like this:
154
155 (((
156 {{code language="none"}}
157 xwiki.users.initialGroups=XWiki.CoolPeople, XWiki.CommunityMembers
158 {{/code}}
159 )))
160
161 * Current members will not be automatically be added to these groups, only new members.
162 * The groups have to be created before being specified as initial groups.
163
164 = Logging =
165
166 See the [[Logging page>>Documentation.AdminGuide.Logging]].
167
168 = Configuring Interwiki links =
169
170 [[Interwiki linking>>http://en.wikipedia.org/wiki/InterWiki]] is a short hand syntax for linking to pages on other websites. For example, you could link to http://en.wikipedia.org/wiki/InterWiki just by typing ~[~[InterWiki@WikiPedia]].
171
172 {{info}}
173 Note that different lists have to be maintained to support this function in XWiki Syntax 1.0 and 2.x.
174 {{/info}}
175
176 {{warning}}
177 The link notation for Interwiki links has changed in XWiki Syntax 2.1. Links should look like this in XWiki Syntax 2.1: ~[~[interwiki:WikiPedia:InterWiki~]~].
178 {{/warning}}
179
180 == Interwiki links (XWiki Syntax 1.0) ==
181
182 Since XWiki renders wiki syntax using the [[Radeox>>http://codemonkeyism.com/forking-radeox-a-new-wiki-render-engine/]] engine, it supports Interwiki links in [[much the same way as SnipSnap>>http://snipsnap.org/space/InterWiki+HowTo]].
183
184 To configure Interwiki links on your wiki:
185
186 * Create a file named ##[location from where you start your container]/conf/**intermap.txt**##
187 * Fill ##intermap.txt## with content like:(((
188 {{code}}
189 IMDB http://us.imdb.com/Title?
190 OpenWiki http://openwiki.com/?
191 SourceForge http://sourceforge.net/
192 TWiki http://twiki.org/cgi-bin/view/
193 Why http://clublet.com/c/c/why?
194 Wiki http://c2.com/cgi/wiki?
195 WikiPedia http://www.wikipedia.com/wiki/
196 {{/code}}
197 )))You can of course add your own entries.
198
199 {{warning}}
200 Radeox's parser for ##intermap.txt## is very fragile. A blank line at the bottom of the file is enough to make it fall over.
201 {{/warning}}
202
203 Restart XWiki (you'll need to restart XWiki every time you change ##intermap.txt##) and try out an Interwiki link. If it does not work, check your ##xwiki.log## file. You'll see if ##conf/intermap.txt## could not be found, or if there was an error parsing it.
204
205 == Interwiki links (XWiki Syntax 2.x) ==
206
207 In order to use Interwiki links in the XWiki Syntax 2.x it is necessary to configure the appropriate list in your ##xwiki.properties## file. Look for the following section:
208
209 {{code language="none"}}
210 #-# [Since 2.5M2]
211 #-# InterWiki definitions in the format alias=URL
212 #-# See http://en.wikipedia.org/wiki/Interwiki_links for a definition of an InterWiki link
213 # Some examples:
214 # rendering.interWikiDefinitions = wikipedia = http://en.wikipedia.org/wiki/
215 # rendering.interWikiDefinitions = definition = http://www.yourdictionary.com/
216 {{/code}}
217
218 = Setting the default editor to use (Wiki or WYSIWYG) =
219
220 Starting with XWiki 3.0, which introduced a revamp of the Administration, you can choose the default editor from "Configuration > Edit Mode Settings" (see below). Starting with XWiki 8.2 you can also configure the default WYSIWYG editor.
221
222 {{image reference="DefaultEditorStarting30.png" width="45%"/}} {{image reference="default-wysiwyg-config.png" width="45%"/}}
223
224 = Configure the WYSIWYG editor =
225
226 See the [[WYSIWYG Editor Configuration>>extensions:Extension.CKEditor Integration.WebHome#HConfiguretheEditor]] page to find out how you can enable or disable editing features.
227
228 = Link URLs =
229
230 With parameters, you can specify what type of links will be made by XWiki.
231
232 == Reverse proxy setup ==
233
234 XWiki can and does run behind reverse proxies such as Apache mod_proxy. Usually the only thing needed is to have the ##x-forwarded-host## http header set to the external URL and XWiki will write links correctly.
235
236 Some reverse proxy software does not set this header and with XWiki 3.0M3 or newer, you can use the ##xwiki.home## parameter in single wiki instances (non farm) to achieve the same result.
237
238 * **xwiki.home** - parameter in ##xwiki.cfg## will be used to make all links pointing to the main wiki on the server. If your main wiki is called "xwiki" but you want your users to access it by going to //www.yoursite.tld// instead of //xwiki.yoursite.tld//, you may set the ##xwiki.home## parameter to //{{{http://www.yoursite.tld/}}}//
239 Since XWiki 3.0M3, this parameter will also work for single wiki instances and will be the final authority if the ##x-forwarded-host## parameter is not set.
240
241 * **xwiki.url.protocol** - with the ##xwiki.url.protocol## parameter in ##xwiki.cfg## you can explicitly specify the protocol as https. This is useful if you are running xwiki behind a reverse proxy which converts https into plain http so xwiki only sees http.
242
243 == Short URLs ==
244
245 It's possible to [[configure XWiki to use shorter URLs>>platform:Main.ShortURLs]].
246
247 = Configure the names of database schemas =
248
249 {{info}}Since 1.6M1{{/info}} Sometimes, especially in a complex environment, we need to control the names of database schemes, other than default.
250
251 * **xwiki.db**: name of database schema for the main wiki (including the name of the wiki in a non-virtual environment, otherwise the database name comes from the hibernate configuration file).
252 * **xwiki.db.prefix**: useful mainly for [[virtual wikis>>Documentation.AdminGuide.Virtualization.WebHome]], where we have a separate database schema for each virtual wiki. This prefix is added to the database schema name after usual mapping between wiki names and schemas. Note that this is also applied to the main wiki database name.
253
254 = Controlling Page Tabs =
255
256 You can do this from the [[Administration>>extensions:Extension.Administration Application#HPresentation]].
257
258 If you wish to turn on/off comments/annotations/attachments/history/information tabs only for a single page you just need to [[define some properties in a script in the page>>platform:DevGuide.Scripting#HControllingPageTabs]].
259
260 Last, if you wish to turn them off based on some programmatic rule (such as display them only for Administrators), you should define the properties in the ##layoutExtraVars.vm## template file from your XWiki installation. For example:
261
262 {{code language="none"}}
263 #if (!$hasAdmin)
264 ## Hide tabs
265 #set($displayDocExtra = false)
266 ## Hide viewer shortcuts in the menu
267 #set ($displayShortcuts = false)
268 #end
269 {{/code}}
270
271 = Configure "Version Summary" behavior =
272
273 When you're editing a page you can add a brief description of your changes in the "Version Summary" field by default (look at [[platform:Features.PageEditing#HCommoneditactions]]). You can disable this feature by setting ##xwiki.editcomment=0## in ##xwiki.cfg##.
274
275 When the "Version Summary" feature is enabled, you can also set "Version Summary" to be mandatory by setting //xwiki.editcomment.mandatory=1// in //xwiki.cfg//. This will show a popup window with the request to write a short comment if there is no comment entered. It doesn't allow you to enter an empty comment. If you want a popup, but you also want to be able to enter an empty comment, set //xwiki.editcomment.suggested=1// in //xwiki.cfg//
276
277 If you set "Version Summary" as mandatory or suggested, you can also remove the "Version Summary" field and use only a popup window for writing a comment. Set //xwiki.editcomment.hidden=0// in //xwiki.cfg// to do this.
278
279 You can use the special fields in the //XWikiPreferences// object instead of editing //xwiki.cfg//. These fields are: //editcomment//, //editcomment_mandatory//, //editcomment_suggested// and //editcomment_hidden//.
280
281 = Configuring Directories =
282
283 XWiki uses the following directories:
284
285 * A Temporary directory. It's used for example to cache images after re-sizing them or store attachments after loading them out of the database.
286 * A Permanent directory. It's used for storing data such as extensions and [[filesystem attachments>>Documentation.AdminGuide.Attachments#HFilesystemAttachmentStore28SinceXWikiEnterprise3.0M229]] which must not be deleted and search indexes which are replaceable but laborious to create.
287
288 To set the permanent directory, you have 2 options:
289
290 * Set the ##xwiki.data.dir## system property when starting the JVM (ie. the Servlet Container's JVM, specifically: ##-Dxwiki.data.dir=...##)
291 * Set the ##environment.permanentDirectory## property in your ##xwiki.properties## file
292
293 Make sure to choose a folder different from the XWiki home on which XWiki (which usually means whatever user running the application server in which XWiki is installed) has write access. For example the standard Debian package use ##/var/lib/xwiki/data## which is usually a good fit for many Linux distributions.
294
295 If the location points to a file or a directory to which XWiki does not have write access to, a warning will be printed in the log and the temporary directory will be used as a default. The temporary directory can be periodically cleaned and all its content deleted so it is critical that it is not used for anything else. Thus it's especially important to set the Permanent directory to not point to the temporary directory.
296
297 The temporary directory is taken from the Servlet Container's ##javax.servlet.context.tempdir## Servlet Context property and thus must be configured at that level. If it is pointed to a file or directory where XWiki cannot write, it will print a warning in the log and attempt to use [[java.io.tmpdir>>http://docs.oracle.com/javase/1.5.0/docs/api/java/lang/System.html#getProperties()]]. If this is not a writable directory, an exception will be thrown.
298
299 {{info}}
300 There are 2 ways to find out what's your current permanent directory:
301 * (since XWiki 9.10) Check the XWiki logs and look for the "Using permanent directory" string.
302 * Put the following in a wiki page (using the wiki editor). Beware that you'll need to have programming rights for this to work:(((
303 {{code language="none"}}
304 {{velocity}}
305 $services.component.getInstance('org.xwiki.environment.Environment').getPermanentDirectory()
306 {{/velocity}}
307 {{/code}}
308 )))
309 {{/info}}
310
311 = Configuring WebDAV (since 1.7) =
312
313 WebDAV support has been added to XWiki beginning with XWiki 1.7. It is very important to note that WebDAV is enabled by default.
314
315 == Securing WebDAV Server ==
316
317 XWiki's WebDAV implementation only supports the [[Basic Access Authentication>>http://en.wikipedia.org/wiki/Basic_access_authentication]] scheme for authenticating WebDAV clients. Because of this reason it is highly recommended that you employ a transport level security mechanism like SSL to protect your clients. You may consult your web application container's documentation to see how this can be achieved.
318
319 == Disabling WebDAV ==
320
321 To disable WebDAV support in your XWiki server, simply edit your ##web.xml## file and remove the url-mapping element for mapping webdav requests. The url-mapping element for WebDAV looks like this:
322
323 {{code language="xml"}}
324 <servlet-mapping>
325 <servlet-name>webdav</servlet-name>
326 <url-pattern>/webdav/*</url-pattern>
327 </servlet-mapping>
328 {{/code}}
329
330 = Redirections =
331
332 XWiki supports defining redirections for incoming requests. To activate this feature modify your ##xwiki.cfg## file and set the following property: {{code}}xwiki.preferences.redirect=1{{/code}}.
333 Then for each redirection you want to add, add a ##XWiki.GlobalRedirect## object to your main wiki's ##XWiki.XWikiPreferences## document. The ##XWiki.GlobalRedirect## object has 2 fields: ##pattern## and ##destination##. The URL received is matched on ##pattern## and if there's a match it's replaced with the value from ##destination##. XWiki then redirects to the new URL.
334
335 = Customizing the PDF export Look & Feel =
336
337 {{info}}
338 In the future we'll want to rewrite the PDF/RTF exports as renderers in the new [[Rendering Module architecture>>extensions:Extension.Rendering Module]]. When this happens this section will be upgraded.
339 {{/info}}
340
341 Here's how the PDF and RTF exports currently work:
342 {{image reference="XWikiExport201010290119.png"/}}
343
344 As shown in the diagram you can customize 4 parts:
345
346 * The templates, pdf.vm and the referenced subparts, pdfhtmlheader.vm, pdfheader.vm, pdffooter.vm, pdftoc.vm, pdfcover.vm, which can be overridden by a copy located in a custom skin
347 * The CSS used to render the content as PDF/RTF. There is no pdf.css by default. It could be created in /templates or in a skin; a copy in a skin, override the one located in /templates
348 * The XHTML2FO XSL transformation. The default one, {{scm project="xwiki-platform" path="xwiki-platform-core/xwiki-platform-oldcore/src/main/resources/xhtml2fo.xsl"}}xhtml2fo.xsl{{/scm}}, is packed in core jar but it could be override by a new one in a template or a xhtml2fo.xsl file in WEB-INF/classes directory, if customization needed.
349 * The FOP XSL transformation. The default one, fop.xsl, is also packed in core jar.
350
351 After the export request triggers XWiki ExportAction, the content of your document is parsed by Velocity to get the initial XHTML content. **[[JTidy>>http://jtidy.sourceforge.net/]]**, a HTML/XHTML syntax checker and pretty printer, will clean the initial XHTML to make it XHTML compliant. No customization is possible in this step.
352
353 In order to provide your own customization you need to start by tweaking the default templates (they can also be copied to a new skin) and/or by creating a new [[XWiki Class>>platform:DevGuide.DataModel]]. To do that simply create a new page called //XWiki.PDFClass// and edit it in class mode (for ex. //{{{http://yourserver.com/xwiki/bin/edit/XWiki/PDFClass?editor=class}}}//). Add the following "Text Area" properties as needed (they are all optional so you only need to define the ones you need to use):
354
355 * ##style##: contains the CSS information that will overwrite or complement the default ##pdf.css## values if they exist. **[[css4j>>https://css4j.github.io/]]**, a CSS API implementation for the Javaâ„¢ platform, will take care of this.
356 * ##xhtmlxsl##: contains the XHTML to FO XSL overriding the default one. It is processed by **[[Apache Xalan>>http://xml.apache.org/xalan-j/]]**, a XSLT processor for transforming XML documents into HTML, text, or other XML document types. Since version 3.0M2 (see issue [[XWIKI-5918>>https://jira.xwiki.org/browse/XWIKI-5918||title="Impossible to override XSLT documents used in the PDF export process"]]) this field needs to be the actual content of the customized ##xhtml2fo.xsl##. Note that you can also use velocity in this field (useful to get the content of an attached .xsl file, which comes in very handy when you need to fill in a big file, since the limit of textarea properties is of 60 000 characters)
357 * ##fopxsl##: contains the FOP to PDF/RTF XSL overriding the default one. It is processed by **[[Apache FOP>>http://xmlgraphics.apache.org/fop/]]**.
358
359 {{warning}}
360 The name of the class must be ##XWiki.PDFClass##.
361 {{/warning}}
362
363 The good thing about fop/xsl-fo is that the xsl-fo document is independent of the final result. So we can export the wiki documents into many formats.
364
365 Then create a new page (say ##XWiki.PDFTemplate##) and add the ##XWiki.PDFClass## object to it.

367 Last use that page when calling the PDF/RTF export using the ##pdftemplate## parameter as in //{{{http://yourserver/xwiki/bin/export/Space/Page?format=pdf&language=en&pdftemplate=XWiki.PDFTemplate}}}//.
368
369 {{warning}}
370 No template is used by default.
371 {{/warning}}
372
373 {{info}}
374 As mentioned the ##style## property stores CSS code. The field is parsed by the Velocity engine, so you can use the [[current color theme>>extensions:Extension.Color Theme Application#HUsingColorThemesvariables]] to style your PDF. Also, you can insert page break in PDF file with //page-break-before// CSS instruction. For example:
375
376 {{code language="css"}}
377 #template('colorThemeInit.vm')
378 h2 {
379 color: $theme.titleColor;
380 }
381
382 td {
383 border-color: $theme.borderColor;
384 }
385
386 h1, .my_Page_break {
387 page-break-before:always;
388 }

393 = Override the PDF Templates =
394
395 == Customize the PDF Footer ==
396
397 By default, the PDF footer will display the page number, the last author and the date on which the last modification was performed. In order to also display a customized message, the template ##pdffooter.vm## must be overridden. To do that, edit the skin class (e.g. //{{{http://yourserver/xwiki/bin/edit/XWiki/XWikiSkins?editor=class}}}//) and add a "TextArea" object named ##pdffooter.vm##:
398
399 {{image reference="OverridePDFFooter.png"/}}
400
401 After adding the ##pdffooter.vm## you might want to edit it (clicking on it opens a detailed editor) and e.g. give it a "Pretty name". In this editor, also set the "Editor" property to "pure text" as otherwise the WYSIWYG-Editor will be used:
402
403 {{image reference="OverridePDFFooterEdit1.png"/}}
404
405 Next, edit the skin page (e.g. //{{{http://yourserver/xwiki/bin/edit/XWiki/DefaultSkin?editor=object}}}//) and add the following code to the ##pdffooter.vm## property:
406
407 {{code}}
408 $msg.Page <span class="page-number"></span> - $msg.get('lastmodifiedby')
409 $xwiki.getUserName($tdoc.author, false)
410 $msg.get('lastmodifiedon')
411 $!xwiki.formatDate($tdoc.date)
412 <div>
413 <p>CustomName SAS. All rights reserved. Confidential and proprietary document. Printed Copies are not controlled.</p>
414 </div>
415 {{/code}}
416
417 To see the changes, just export any wiki page:
418
419 {{image reference="OverridePDFFooterFinal.png"/}}
420
421 == Customize the PDF Cover ==
422
423 This could be useful when you want for instance to add the company's logo to the PDF cover. In order to do this, the template ##pdfcover.vm## must be overridden. Just like for the PDF header, a "TextArea" property named ##pdfcover.vm## must be added to the XWiki.XWikiSkins class (e.g. //{{{http://yourserver/xwiki/bin/view/XWiki/XWikiSkins?editor=class}}}//).
424
425 {{image reference="OverridePDFCover.png"/}}
426
427 Next, edit the skin page (e.g. //{{{http://yourserver/xwiki/bin/edit/XWiki/DefaultSkin?editor=object}}}//) and add the following code to the ##pdfcover.vm## property:
428
429 {{code}}
430 <img src="$xwiki.getSkinFile("logo.png")"/>
431
432 <div style="text-align: center; width: 100%;">
433 <h1>
434 #set($title = "$!pdfdoc.display('title', 'rendered')")
435 #if($title == '')
436 $escapetool.xml($!doc.displayTitle)
437 #else
438 $escapetool.xml($title)
439 #end
440 </h1>
441 <br />
442 <br />
443 $!xwiki.getUserName($tdoc.author, false)
444 <br />
445 $!xwiki.formatDate($tdoc.date)
446 </div>
447 {{/code}}
448
449 The last step consists of attaching the image "logo.png" to the skin:
450
451 {{image reference="OverridePDFCoverFinal.png"/}}
452
453 == Override the CSS rules ==
454
455 In order to use your own template when exporting a page as PDF, you need to create a class in the XWiki space and name it PDFClass. Next, edit the page in "Class" mode (e.g. //{{{http://yourserver/xwiki/bin/edit/XWiki/PDFClass?editor=class}}}//) and add the following ##TextArea## properties:
456
457 * ##style##: contains the CSS rules that will override the default ##pdf.css## values; by default, there won't be a ##pdf.css## file on your filesystem, but you can create it in the folder ##\webapps\xwiki\templates\## or specify it in your skin page
458 * ##xhtmlxsl##: contains the XHTML2FO XSL transformation that will override the default one
459 * ##fopxsl##: contains the FOP XSL transformation that will override the default one
460
461 For each property added, make sure to set the ##Content## property metadata to ##PureText## in order to not get the WYSIWYG editor which would make it complex to enter XML/XSL.
462
463 {{image reference="CreatePDFClass.png"/}}
464
465 Then, create the wiki page for which your want to customize the PDF export (e.g. XWiki.PDFTemplate) and add a "XWiki.PDFClass" object to it.
466
467 Supposing your wiki page contains a table, you have to edit it in "Wiki" mode and add a style parameter as shown below:
468
469 {{code}}
470 (% class="mytable" %)
471 |=Column 1|=Column 2
472 | data|data
473 {{/code}}
474
475 Next, edit the page in "Objects" mode and write your own CSS rules in the "style" property:
476
477 {{image reference="CreatePDFTemplate.png"/}}
478
479 Because no template is used by default, you need to specify the ##pdftemplate## parameter in the URL in order to use your own template: //{{{http://yourserver/xwiki/bin/export/XWiki/PDFTemplate?format=pdf&pdftemplate=XWiki.PDFTemplate}}}//.
480
481 {{image reference="CustomizedPDF.png"/}}
482
483 {{info}}
484 Even though RTF export is expected to work the same way, there are still some isues to be solved affecting how CSS properties control the final layout.
485 {{/info}}
486
487 {{warning}}
488 If some CSS styling doesn't work on PDF export, you could check if CSS instruction is supported by XSL-FO on [[Apacheâ„¢ FOP Compliance Page>>https://xmlgraphics.apache.org/fop/compliance.html]].
489 Furthermore, you can not use multiple attributes to select a CSS element (see issue: [[XWIKI-14653>>https://jira.xwiki.org/browse/XWIKI-14653]]).
490 {{/warning}}
491
492 == Override the xhtml2fo.xsl rules ==
493
494 As explained above, the entire code of {{scm project="xwiki-platform" path="xwiki-platform-core/xwiki-platform-oldcore/src/main/resources/xhtml2fo.xsl"}}xhtml2fo.xsl{{/scm}} needs to be copied in the xhtmlxsl textarea and then customized.
495
496 For example, to disable the generation of clickable URLs in the PDF, modify the following section:
497 {{code}} <xsl:template match="html:a[@href]" mode="transform">
498 <fo:basic-link xsl:use-attribute-sets="a-link">
499 <xsl:call-template name="process-a-link"/>
500 </fo:basic-link>
501 </xsl:template>{{/code}}
502 as
503 {{code}} <xsl:template match="html:a[@href]" mode="transform">
504 <fo:inline>
505 <xsl:call-template name="process-a-link"/>
506 </fo:inline>
507 </xsl:template>{{/code}}
508 or disable the generation of clickable URLs for some specific href links in the PDF
509 {{code}} <xsl:template match="html:a[@href]" mode="transform">
510 <xsl:choose>
511 <!-- disable these internal links ("data-parent" attribute start with "#accordion" or href is "#my_anchor") -->
512 <xsl:when test="starts-with(@data-parent,'#accordion') or @href = '#my_anchor'">
513 <fo:inline>
514 <xsl:call-template name="process-a-link"/>
515 </fo:inline>
516 </xsl:when>
517 <xsl:otherwise>
518 <fo:basic-link xsl:use-attribute-sets="a-link">
519 <xsl:call-template name="process-a-link"/>
520 </fo:basic-link>
521 </xsl:otherwise>
522 </xsl:choose>
523
524 </xsl:template>{{/code}}
525
526 == Debugging PDF export ==
527
528 To inspect contents of created XHTML file (and be able to style it) - turn on logging <xwiki>/xwiki/bin/view/AdminGuide/Logging and set //com.xpn.xwiki// level to //DEBUG//. After PDF export action, xwiki log file containing intermediates states XHTML code after theses lines:
529
530 {{code language="none"}}
531 DEBUG c.x.x.p.i.PdfExportImpl - Cleaning HTML: //(show XHTML code without style)//
532 DEBUG c.x.x.p.i.PdfExportImpl - Cleaned XHTML:

541 = Configuring Wiki Syntaxes and default Syntax =
542
543 To know how to configure the [[Wiki syntaxes>>platform:Main.XWikiSyntax]] that are available to the user when writing wiki pages, check the [[Rendering Administration Application>>extensions:Extension.Rendering Administration Application]].
544
545 = Title behavior =
546
547 The following configuration parameters (found in ##xwiki.cfg##) can be used to control title behavior:
548
549 {{code language="none"}}
550 #-# Defines whether title handling should be using the compatibility mode or not. When the compatibility
551 #-# mode is active, XWiki will try to extract a title from the document content.
552 #-# If the document's content first header (level 1 or level 2) matches the document's title
553 #-# the first header is stripped.
554 #-# The default value is 0.
555 # xwiki.title.compatibility=1
556
557 #-# Defines the maximum header depth to look for when computing a document's title from its content. If no header
558 #-# equal or lower to the specified depth is found then the computed title falls back to the document name.
559 #-# The default value is 2.
560 # xwiki.title.headerdepth=2
561
562 #-# Defines if setting the title field must be mandatory in the WYSIWYG and Wiki editors. It is mandatory when this
563 #-# property is set to 1. The default value is 0 (not mandatory).
564 # xwiki.title.mandatory=0
565 {{/code}}
566
567 = Link Label Generation =
568
569 Starting with XWiki Syntax 2.0 it's possible to configure how labels are generated by the system when the user doesn't provide one (e.g. ##[[platform:Main.WebHome]]##).
570
571 Her's an extract from the ##xwiki.properties## file which is where this feature is configurable:
572
573 {{code language="none"}}
574 #-# [Since 1.8RC2]
575 #-# Specifies how links labels are displayed when the user doesn't specify the label explicitly.
576 #-# Valid values:
577 #-# %w: wiki name
578 #-# %s: full space name (e.g. space1.space2)
579 #-# Note: Prior to 7.4.2/8.0M2 this was only displaying the last space name
580 #-# %ls: last space name. New in 7.4.2/8.0M2
581 #-# %p: page name
582 #-# %np: nested page name (i.e. will display the space name for Nested Pages). New in 7.4.2/8.0M2
583 #-# %P: page name with spaces between camel case words, i.e. "My Page" if the page name is "MyPage"
584 #-# %NP: nested page name with spaces between camel case words, i.e. "My Page" if the page name is "MyPage".
585 #-# New in 7.4.2/8.0M2
586 #-# %t: page title
587 #-#
588 #-# Note that if the page title is empty or not defined then it defaults to %np. This is also the case
589 #-# if the title cannot be retrieved for the document.
590 #-#
591 #-# The default is "%np". Some examples: "%s.%p", "%w:%s.%p".
592 # rendering.linkLabelFormat = %np
593 {{/code}}
594
595 = Rendering Cache =
596
597 See the [[Performance page>>Documentation.AdminGuide.Performances.WebHome#HRenderingcache]].
598
599 = Allowed Pages for Inactive Users =
600
601 The //xwiki.cfg// configuration file includes a property called ##xwiki.inactiveuser.allowedpages##. This property can be used to build a whitelist of pages that can be read by inactive users. The format that should be used is a comma-separated list of pages that users that are marked as inactive are allowed to see.
602
603 This property is needed due to the fact that in XWiki, some users can be marked as inactive, for example when enabling user email verification in the administration. An inactive user has an account, but the account needs to be validated in order for the user to be able to access the wiki. Access rights do not apply to inactive users (they are recognized neither as XWikiGuest nor as members of XWikiAllGroup).
604
605 {{info}}
606 Inactive users are always allowed to see the //XWiki.AccountValidation// page in order to validate their account.
607 {{/info}}
608
609 = Rendering Transformations =
610
611 You can control which [[Transformations>>rendering:Main.Architecture]] are active (by default the [[Macro>>rendering:Main.Architecture]] and [[Icon>>rendering:Main.Transformations#HIconTransformation]] ones are active by default) by editing ##xwiki.properties##:
612
613 {{code language="none"}}
614 #-# [Since 2.6RC1]
615 #-# Controls what transformations will be executed when rendering content.
616 #-# A transformation modifies the parsed content. For example the Icon transformation replaces some characters with
617 #-# icons, a WikiWord transformation will automatically create links when it finds wiki words, etc.
618 #-# Note that the Macro transformation is a special transformation that replaces macro markers by the result of the
619 #-# macro execution. If you don't list it, macros won't get executed.
620 #-# The default value is: rendering.transformations = macro, icon
621 {{/code}}
622
623 For example if you wish to turn off the Icon Transformation in order to not render emoticons, you'd have to define the following property: {{code language="none"}}rendering.transformations = macro{{/code}}.
624
625 = Securing Groovy Scripts =
626
627 See:
628
629 * The [[Commons Groovy Module>>extensions:Extension.GroovyModuleCommons]]
630 * The [[Platform Groovy Module>>extensions:Extension.GroovyModulePlatform]]
631
632 = Lock Duration =
633
634 By default, when a user starts editing a page, a lock will be set on that page, see [[Page Editing>>Documentation.UserGuide.Features.PageEditing#HLocking]]. The lock is valid by default for 30 minutes, after which it gets invalidated.
635
636 In order to increase this duration, you have 2 options:
637
638 * Add a property named ##lock_Timeout## to your ##xwiki.cfg## configuration file, and set the value in seconds (and restart XWiki). For example for 15 minutes: ##lock_Timeout = 900##.
639 * Or add the configuration in the wiki itself:
640 ** Edit the ##XWiki.XWikiPreferences## document using the class editor
641 ** Add a Number property named ##lock_Timeout## (case sensitive)
642 ** Edit the ##XWiki.XWikiPreferences## document using the object editor
643 ** Find the ##lock_Timeout## property and put the desired number of *seconds* a lock should be valid for
644 ** Don't forget to save the document
645
646 = Section Editing =
647
648 By default section editing is limited to level 1 and level 2 sections. This can be controlled by editing ##xwiki.cfg##:
649
650 {{code}}
651 #-# This parameter controls the depth of sections that have section editing.
652 #-# By default level 1 and level 2 sections have section editing.
653 xwiki.section.depth=2
654 {{/code}}
655
656 You can also enable/disable section editing with:
657
658 {{code}}
659 #-# This parameter will activate the sectional editing.
660 xwiki.section.edit=1
661 {{/code}}
