eclipse / epsilon

Epsilon is a family of Java-based scripting languages for automating common model-based software engineering tasks, such as code generation, model-to-model transformation and model validation, that work out of the box with EMF (including Xtext and Sirius), UML (including Cameo/MagicDraw), Simulink, XML and other types of models.

EGL: Outdented TemplateOperation causes StringIndexOutOfBoundsException #90

Closed Arkaedan closed 2 months ago

Arkaedan commented 2 months ago

Outdented TemplateOperation causes StringIndexOutOfBoundsException when used in a file that has other outdented sections.

Example:

[%for (f in Sequence{1}) {-%]
    [%=f%]
[%}%]
[%=t()%]
[%
@template
operation t(){-%]
    [%=1%]
[%}%]

Which causes this error:

begin 4, end 8, length 4
