PatternSkin Customization
Guidelines how to create and customize page templates of the PatternSkin. For styling your TWiki using stylesheets, see
PatternSkinCssCookbook.
First Read: How to modify PatternSkin templates
Everything you see on the common 'view' page is written by the
view
template. For pattern skin this file is
/templates/view.pattern.tmpl
.
We describe two approaches to override this template:
- By creating a custom skin file in the
templates
directory
- By creating a custom topic template
Which approach is best?
- If you want to change the appearance for a lot of pages or even site-wide, the template approach is the easiest.
- If you want to change the appearance of a single topic, or a set of topics, use a topic template.
The template approach
To change templates you will need shell access. If you don't have this read on below in
The topic template approach.
The quickest way to change the view template would be to simply change the text in the template. A safer way - strongly recommended, because it will survive a TWiki update - is to create your own custom skin. That may sound like an awful lot of work, but in reality a skin may be as much as 1 file that consists of only a few lines of code.
Example
Let's say you want to simplify the bottom toolbar and remove all links except for "More topic actions". You would need to target
%TMPL:DEF{"topicactionbuttons"}%
, which is located in
view.pattern.tmpl
.
The steps you would need:
- Think up a name for your skin. Let us use
myskin
for now.
- Create a new (empty) view template file in
/templates
called view.myskin.tmpl
.
- In
view.myskin.tmpl
you write:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"top:toolbarbuttons"}%%TMPL:P{"more_link"}%%TMPL:END%
- For testing, view any topic and append to the topic name:
?cover=myskin
. You should see an effect now.
- To make the changes visible on all pages, go to Main.TWikiPreferences (to keep TWikiPreferences intact) and write:
* Set COVER = myskin
or write
* Set SKIN = myskin,pattern
Test by appending
?cover=myskin
to the url.
The topic template approach (using VIEW_TEMPLATE)
Template overrides can be written in a topic, a so-called
topic template. Topic template names end with
Template
, for instance
BlogPostViewTemplate
.
Call this template by setting
VIEW_TEMPLATE
:
* Set VIEW_TEMPLATE = BlogPostView
We can use the same example as above. In a topic write:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"top:toolbarbuttons"}%%TMPL:P{"more_link"}%%TMPL:END%
You can also test this by appending
?template=PersonalInfoView
to the url.
Reference: pattern skin template INCLUDE tree
The
view
script invokes the
view
template:
view
twiki
css
viewtopbar
%SYSTEMWEB%.WebTopBar
viewleftbar
%WEB%.WebLeftBar
viewtopicactionbuttons
viewbottombar
%SYSTEMWEB%.WebBottomBar
Read-only skin mode
The PatternSkin can be turned into read-only mode. This is mainly useful if you have TWiki application pages or dashboards where you do not want regular users to change content. The read-only mode is enabled with a READONLYSKINMODE preferences setting set to 1 in the
Main.TWikiPreferences (site level), in a
WebPreferences (web level) or in any topic (page level):
* Set READONLYSKINMODE = 1
If set, the edit and attach buttons on top, and the topic action bar at the bottom are removed. There is a hard to find edit link for people who need to edit content: The topic revision info at the bottom has a dash before the
WikiName that is turned into an edit link, such as:
Topic revision: r7 - 2011-05-18 - TWikiAdminUser
Please note that this is
not a replacement for access control, use it in addition to
TWikiAccessControl.
Logo
How can I change the web logo?
By default the logo at the top left of each web points to the image with name
logo.gif
that is attached to each web's
WebPreferences.
The default variables that cause this behavior are defined in
TWikiPreferences.
Redefine your custom variables in
Main.TWikiPreferences (to keep
TWikiPreferences intact):
* Set WEBLOGONAME = logo.gif
* Set WEBLOGOIMG = %PUBURLPATH%/%BASEWEB%/%WEBPREFSTOPIC%/%WEBLOGONAME%
* Set WEBLOGOURL = %SCRIPTURLPATH{"view"}%/%BASEWEB%/%HOMETOPIC%
* Set WEBLOGOALT = Home
There are 2 ways to change the logo in a web:
Using logo.gif:
- Create a new image named
logo.gif
and attach it to the web's WebPreferences topic. PatternSkin's stylesheet assumes the logo is 40px high. More about that later.
- You can also upload the image with FTP to
/pub/YourWeb/WebPreferences/
.
- Copy the above instructions ("Redefine your custom variables") and insert your logo name.
Using a new filename:
* Set WEBLOGONAME = your-logo-name.gif-or-png
- Copy the above instructions ("Redefine your custom variables") and insert your logo name.
How do I set a site-wide logo?
There is a bunch of site-wide logo variables in
Main.TWikiPreferences:
WIKILOGOIMG
,
WIKILOGOURL
and
WIKILOGOALT
.
To change only the web logo image to site-wide, in
Main.TWikiPreferences set:
* Set WEBLOGOIMG = %WIKILOGOIMG%
My logo does not fit the top bar
See
I want to change the height of the top bar
I want to change the white space above and below the logo
Change the table style in topic
WebTopBar. The default top padding is 11px.
Top bar
The search box won't find topics in other webs
In
WebTopBar you can find the line:
<input type="hidden" name="web" value="%BASEWEB%" />
To search all webs, write:
<input type="hidden" name="web" value="all" />
To search a couple of webs, for instance the webs Main and TWiki, write:
<input type="hidden" name="web" value="Main,TWiki" />

Search variable
I want to change the height of the top bar
The top bar is 64 pixels high by default.
Using templates:
Using either a template or a topic template, copy this definition in your custom template:
%TMPL:DEF{"topbardimensions"}%
#patternTopBar,
#patternClearHeaderCenter,
#patternClearHeaderLeft,
#patternClearHeaderRight,
#patternTopBarContentsOuter {
height:64px; /* top bar height; make room for header columns */
overflow:hidden;
}
%TMPL:END%
And change the number from 64px to a different value.
Using style sheets:
Create a new stylesheet with above definition in it, attach it to a topic and point USERLAYOUTURL
to that topic attachment. See PatternSkinCssCookbook about creating custom styles.
I want to set or change the top background image
The image at the top is called "header art" - commonly the top image found on blog sites. The image that is displayed by default is set by the variable
WEBHEADERART
, defined in
TWikiPreferences.
Redefine your custom variables in
Main.TWikiPreferences (to keep
TWikiPreferences intact):
* Set WEBHEADERART = %PUBURLPATH%/%SYSTEMWEB%/PatternSkin/TWiki_header.gif
* Set WEBHEADERBGCOLOR = somehexcolor (no quotes, for example: #ffffff)
You can also set
WEBHEADERART
per web, by defining the variable in the Web's WebPreferences.
I want to have the web color in the top bar
Redefine
WEBHEADERBGCOLOR
in
Main.TWikiPreferences (to keep
TWikiPreferences intact):
* Set WEBHEADERBGCOLOR = %WEBBGCOLOR%
I want to remove the Jump and Search boxes from the top bar
If you have localization enabled, you will also see a language dropdown box at the far right.
You can remove these items from
WebTopBar.
I want to hide the top bar
Using templates:
The view template is populated with page elements using template inclusions:
%TMPL:INCLUDE{"page"}%
%TMPL:INCLUDE{"viewtopbar"}%
%TMPL:INCLUDE{"viewtoolbar"}%
%TMPL:INCLUDE{"viewleftbar"}%
%TMPL:INCLUDE{"viewrightbar"}%
%TMPL:INCLUDE{"viewtopicactionbuttons"}%
%TMPL:INCLUDE{"viewbottombar"}%
Each included template draws a part of the screen.
Omit
%TMPL:INCLUDE{"viewtopbar"}%
to hide the top bar.
Another approach is to clear the contents of module
topbar
with an empty definition. Using either a template or a topic template, write in your custom template:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"topbar"}%%TMPL:END%
and add:
%TMPL:DEF{"topbardimensions"}%#patternTopBar,
#patternClearHeaderCenter,
#patternClearHeaderLeft,
#patternClearHeaderRight,
#patternTopBarContentsOuter {
height:0px;
}%TMPL:END%
Using style sheets:
See
PatternSkinCssCookbookNoTopBar
Left bar
I want to hide the left bar
Using templates:
Omit
%TMPL:INCLUDE{"viewleftbar"}%
to hide the left bar, or in a custom template clear it using
%TMPL:DEF{"leftbar"}%%TMPL:END%
%TMPL:DEF{"leftbardimensions"}%%TMPL:END%
Using style sheets:
See
PatternSkinCssCookbookNoLeftBar
I want to make the left bar wider
Using templates:
The left bar is 12 em wide by default.
Using templates:
Using either a template or a topic template, copy this definition in your custom template:
%TMPL:DEF{"leftbardimensions"}%#patternOuter {
margin-left:12em;
}
#patternLeftBar {
width:12em;
margin-left:-12em;
}%TMPL:END%
And change the number from 12em to a different value (3 occurrences).
Buttons
I want to hide the edit buttons from certain users
It may defy the wiki-ness of your TWiki installation, but in certain circumstances it could be useful to hide the edit buttons from users that are not logged in, for instance for clients that have gotten viewing rights only.
Using either a template or a topic template, 'empty'
top:toolbarbuttons
and
topicaction
by writing:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"top:toolbarbuttons"}%%TMPL:END%
%TMPL:DEF{"topicaction"}%%TMPL:END%
In the user page of
TWikiGuest, set the cover to
* Set COVER = customer
By default this topic is editable only by TWiki admins.
I want to remove the History button from the bottom
All action links and buttons are defined in
viewtopicactionbuttons.tmpl
. The bottom history link is defined in DEF
action_revisions
%TMPL:DEF{"topicactionbuttons"}%
%TMPL:P{"action_activatable_edit_or_create"}%
%TMPL:P{"action_activatable_attach"}%
%TMPL:P{"action_printable"}%
%TMPL:P{"action_revisions"}%
%TMPL:P{"action_backlinks_simple"}%
%TMPL:P{"action_raw_or_view"}%
%TMPL:P{"action_activatable_raw_edit"}%
%TMPL:P{"activatable_more"}%
%TMPL:END%
To hide that link, In a custom skin view template
view.myskin.tmpl
empty
action_revisions
by replacing it with an empty string:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"action_revisions"}%%TMPL:END%
I want to put the bottom links as buttons at the top
The default definition in
view.pattern.tmpl
is:
%TMPL:DEF{"top:toolbarbuttons"}%%TMPL:P{"activatable_edit_or_create"}%%TMPL:P{"activatable_attach"}%%TMPL:END%
Create a new skin by creating a file
view.myskin.tmpl
in the
templates
directory. Write in it:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"top:toolbarbuttons"}%%TMPL:P{"history_history_link"}%%TMPL:END%
View any topic with
?skin=myskin,pattern
, or set the
SKIN
variable to
myskin,pattern
.
This will remove the Edit and Attach buttons, and place a History button at the top.
You will probably not just want to have the History button there. Other button include names are:
create_topic_link
raw_edit_link
view_topic_link
activatable_attach
activatable_edit_or_create
more_link
activatable_printable
backlinks_web_link
backlinks_all_link
backlinks_link
history_rdiff_link
history_history_link
raw_link
Other page parts
I want to insert text outside of the topic content
PatternSkin has 2 'buckets' to write additional content to:
contentheader
and
contentfooter
, both defined in
view.pattern.tmpl
. These containers can contain text or html and are placed directly before and after the topic text.
Both modules are wrapped in CSS containers:
-
contentheader
- wrapped in div
of class twikiContentHeader
-
contentfooter
- wrapped in div
of class twikiContentFooter
To put contents
before the main text, use the custom skin approach as described above.
So our custom template contains:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"contentheader"}%This is the text before%TMPL:END%
Use the same procedure for contents to be put
after the topic text:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"contentfooter"}%This is the text after%TMPL:END%
I want to place the form at the top
Pattern skin has 2 buckets for the form:
formtop
(form at the top) and
formbottom
(form at the bottom). The default definition is:
%TMPL:DEF{"formtop"}%%TMPL:END%
%TMPL:DEF{"formbottom"}%%TMPL:P{"form"}%%TMPL:END%
You simply swap the bucket contents. Using either a template or a topic template, write in your custom template:
%TMPL:INCLUDE{"view"}%
%TMPL:DEF{"formtop"}%%TMPL:P{"form"}%%TMPL:END%
%TMPL:DEF{"formbottom"}%%TMPL:END%
I want to put the topic form in a twisty
The attachment tables are placed in a open/close twisty. You can do the same for the topic form.
Edit
templates/formtables.pattern.tmpl
to have this code:
%{ These templates define the form attached at the bottom of viewed page. }%
%TMPL:DEF{"starttopicformwisty"}%%TWISTY{id="topicformlist" mode="div" remember="on" link="%MAKETEXT{"Form"}%" showimgleft="%ICONURLPATH{toggleopen}%" hideimgleft="%ICONURLPATH{toggleclose}%"}%%TMPL:END%
%TMPL:DEF{"endtopicformwisty"}%%ENDTWISTY%%TMPL:END%
%{ Start of form table }%
%TMPL:DEF{FORM:display:header}%<div class="twikiForm">%TMPL:P{"starttopicformwisty"}%
<table class='twikiFormTable' border='1'>%TMPL:P{FORM:display:header:headerrow}%%TMPL:END%
%{ Header }%
%TMPL:DEF{FORM:display:header:headerrow}%<tr><th class='twikiFormTableHRow twikiFirstCol' colspan='2'>
[[%A_TITLE%]]
</th></tr>%TMPL:END%
%{ Each row }%
%TMPL:DEF{FORM:display:row}%<tr valign='top'><td class='twikiFormTableRow twikiFirstCol' align='right'> %A_TITLE% </td><td>
%A_VALUE%
</td></tr>%TMPL:END%
%{ Footer }%
%TMPL:DEF{FORM:display:footer}%</table>%TMPL:P{FORM:display:footer:editlink}%
%TMPL:P{"endtopicformwisty"}%</div><!-- /twikiForm -->%TMPL:END%
To give the twisty toggle link the same style as the attachment twisty link, add this to pattern skin's
style.css
:
.twikiForm .twistyTrigger .twikiLinkLabel {
font-size:122%; /* h4 size */
font-weight:bold;
}
