The Persistency web was created to merge into a single twiki web the information that was previously scattered across different webs for the Persistency subprojects.

Tips and Tricks

  • The hierarchical navigation menu in the WebLeftBar was created using the sections defined in the HierarchicalNavigation topic.
    • In HierarchicalNavigation, the children of the current topic are computed dynamically using %SEARCH{"'%BASETOPIC%'" web="%BASEWEB%" type="query" nonoise="on"}%. If the current topic is Cool, Note that this query will display all topics whose parent is 'Cool' but not those whose parent is 'Persistency.Cool'.
    • An alternative search to display all children of the current topic is %METASEARCH{type="parent" web="%WEB%" topic="%TOPIC%"}%. If the current topic is Cool, Note that this query will display both those topics whose parent is 'Cool' and those whose parent is 'Persistency.Cool'.
  • The size of the left bar was changed by modifying the default skin of this web (rather than through templates, as described in PatternSkinCustomization).
  • The size of the "h3" headers was changed by modifying SYSTEMWEB%.PatternSkin's default style.css (see PatternSkinCss) and setting "Set USERSTYLEURL = %PUBURLPATH%/%WEB%/WebUtilities/headers.css" in the WebPreferences topic. This was done because the default "h3" is bold and appears larger than "h2"; I often use "h4" instead of "h3" for this reason, but in some pages I wanted to generate a TOC and tables of contents look weird if all "h3" headers are missing.
  • You may choose your icons for the left bar from the TWikiDocGraphics page or you may import your own (use 16x16 icons).
  • The format for displaying not-existing topics is controlled by the NEWLINKFORMAT. The default for this twiki site is set in TWikiPreferences#Miscellaneous_Settings. See also the discussion in ChangeFormattingOfBumpyWord and RemoveQuestionMarkLinks. You may change the default only for one particular topic (e.g. PersistencyTeam) either by the "Edit Topic Preference Settings" in "More Topic Actions", or by adding the new variable definition at the beginning of the topic (you may also include it in a comment, <!--...-->).
  • Some of the topics available in this twiki are not maintained in the repository, but are instead included from other sites (e.g. from the original AFS-based web sites of the three projects). One such example is the PersistencyReleaseNotes topic which includes the release notes available directly at
  • You can set permissions to write on a single topic by changing the ALLOWTOPICCHANGE parameter (by editing the metadata settings, or hiding it between comments). Note that ALLOWTOPICCHANGE (in topic) overrides ALLOWWEBCHANGE (in WebPreferences): see TWikiAccessControl.
  • The CORALCOOL:xxx shorthand can be used to create a link to the CORALCOOL-xxx Jira ticket. This translation is implemented using the InterwikiPlugin technology (in fact, the page source for all links created in this way belong to class="interwikiLink"). Many interwiki links are globally defined for all CERN Twikis on the TWiki.InterWikis configuration page. In addition, Persistency.WebPreferences defines Persistency.WebInterWikis as the Interwiki configuration page for the Persistency web.
