v0.1.5

Next to a large number of small bug fixes and improvements, this release introduces a number of API and behaviour changes, that have the potential to break existing workflows using Loki:

What's changed

• Expression nodes no longer have a source property (#118)
• The monolithic SCC wrapper transformation has been replaced by individual, composable transformation steps (#124)
• Statement function injection is now happening on-the-fly in the parse tree translation to Loki-IR (#132)
• API under ExpressionMapper has been changed, making behaviour static class properties (#138)
• The ecphys entry point of loki-transform.py has been retired and fully integrated into the convert command (#142)
• Transformation no longer recurses by default into contained scopes (#136)
• The CMake integration has been refactored, consolidating on a single CMake function loki_transform to call the loki-transform.py script, and the loki_transform_target function to automatically update a target's source files and copy compilation attributes for transformed files. loki_transform_target is retained for compatibility but marked as deprecated and will be removed in the future (#166)

What's new

• A transformation that allows inlining contained member subroutines (#130)
• The hoisting mechanism in the SCC transformations has been replaced by a recursive hoisting transformation (#156)
• SCC transformations can now also be applied to loops in the driver routine (#150)
• A graphical visualization of the Loki IR using Graphviz via the pretty_visualize utility function (#146)
