Please go to GlobalSearchAndReplace to perform a global replace operation.

Plugin Settings

Plugin settings are stored as preferences variables. To reference a plugin setting write %<plugin>_<setting>%, i.e. %GLOBALREPLACEPLUGIN_SHORTDESCRIPTION%

  • One line description, is shown in the TextFormattingRules topic:
    • Set SHORTDESCRIPTION = Global search and replace functionality across all topics in a web

Examples

Example 1: Changing a string

  1. Click Edit from a page
  2. Copy the string you want to change to the "Replace search string" field. This is the field you want to replace.
  3. Select web and a search string ( Sandbox, TestTopic )
  4. Replace any other non-numeric and non-alphabetic [character] with [\character], e.g. [}] with [\}]. This applies to "Replace search string" field only.
    • E.g. \%EDITCELL\{checkbox, 3, Input data exchange, ... \}\%
  5. Copy-paste the string to the "Replace string" field and modify it as you choose
  6. Press the "Search"-button and verify that the replaced and replacing strings are as expected
  7. Set all the checkboxes of the strings you want to replace. You can also select "Set all"
  8. Click "Replace all check-marked hits"

Example 2: Inserting a line under another line

  1. Follow the previous example to the point where "Replace search string" is inserted
  2. Use [(\n)] in the "Replace search string", at the end of the line. This will be stored for use in the "Replace string". You can reference it by [$x], where [x] is a number 1-9.
    • E.g. We want to replace a line which ends to a string [Shutdown}% |]. "Replace search string": Shutdown\}\% \|(\n) and "Replace string": Shutdown}% |$1Something$1asdf$1
  • Note: Using this trick you can also insert a line before another line, by writing:
    • E.g. We want to insert a line before another line, which begins with a string [| Keywords: |]. "Replace search string": \| \*Keywords\:\* \|(.*?)(\n) and "Replace string": Something $2| *Keywords: |$1$2
    • E.g. We want to replace a line which begins with a string [| Keywords: |] and ends with or contains the string [Interrupt}%]. "Replace search string": \| \*Keywords\:\* \|(.*?)Interrupt\}\%(.*?)(\n) and "Replace string": Something $3| *Keywords: |$1Interrupt}%$2$3
