Element <trace>

The <trace> element is a debugging tool that controls the display of the instructions being executed by the IsisScript interpreter.

It activates or deactivates the echo of the code to the standard output, helping developers follow the execution flow.

Usage​

  • Allowed content: Text (On, Off, BR, Table) or <pft>.
  • Parent elements: <do>, <function>, <hl>, <IsisScript>, <loop>, <section>, <update>

Syntax​

<trace>MODE</trace>

Modes (Content)​

  • On: Activates normal trace mode.
  • BR: Activates line-by-line mode (adds HTML line breaks <br> for readability in browsers).
  • Table: Activates table mode (displays execution trace inside an HTML table structure).
  • Off: Deactivates tracing.

Example​

<trace>BR</trace>
<field action="replace" tag="100">Debug this value</field>
<trace>Off</trace>
