Changes

Page is focused on the old [[Mark_II|Mark II]] ConTeXt version, though <tt>\show...< /tt> commands are still the same. Work-in-progress page on current [[Inside ConTeXtLMTX]] | version is [[VisualsDebugging]] >.

  There's a whole lot of commands that help you analyzing and debugging your ConTeXt documents. Most of them start with <{{cmd>|show...</cmd> }} or <{{cmd>|trace...</cmd>}}. While <{{cmd>|showsomething</cmd> }} is a command that immediately inserts something, <{{cmd>|tracesomethingtrue</cmd> }} or ...<tt>false</tt> is a switch that influences the behaviour of some other commands. You can check the setting with <{{cmd>|iftrace...</cmd>}}. In the following we leave out the boolean value (true or false).
