# Enso Compiler IR
|
||
|
|
|
||
|
|
Enso IR, currently implemented in Scala, with base class
|
||
|
|
`org.enso.compiler.core.IR`, is created from the output of the native
|
||
|
|
[parser](../parser/README.md). The IR is an immutable annotated AST subjected to
|
||
|
|
multiple passes. Every pass is a class implementing the
|
||
|
|
`org.enso.compiler.pass.IRPass` interface.
|
||
|
|
|
||
|
|
See [Runtime roadmap - static analysis](../runtime-roadmap.md#static-analysis)
|
||
|
|
for future goals.
|
||
|
|
|
||
|
|
## Visualization
|
||
|
|
|
||
|
|
The IR can be visualized using `-Denso.compiler.dumpIr` system property. This
|
||
|
|
will output a `.dot` file in [GraphViz](www.graphviz.org) format in the
|
||
|
|
`ir-dumps` directory for each IR in the program. The _dot_ file format is a
|
||
|
|
minimal textual format, that can be converted to a graphical representation
|
||
|
|
using the `dot` command from the GraphViz package. For example, on Ubuntu,
|
||
|
|
install `dot` with `sudo apt install graphviz`. Then, convert the `.dot` file to
|
||
|
|
a `.svg` image with `dot -Tsvg -o <output>.svg <input>.dot`. An example is:
|
||
|
|
|
||
|

|

See `org.enso.compiler.dump.IRDumper`.
