# Readme for C1Visualizer

# Developing the C1Visualizer
5+
6+
C1Visualizer is based on Netbeans 26 but can be often be worked on with later releases or with any
7+
IDE that supports Maven. Care must be taken not to commmit anything that would keep it from working
8+
with 26 so any automatic changes to property file updates by later NetBeans versions shouldn't be
9+
pushed. The packaged product is built by:
10+
```
11+
cd C1Visualizer
12+
mvn package
13+
```
14+
15+
# Regenerating the cfg file parser
16+
17+
The cfg file parser is based on CoCo/R which hasn't been updated since 2018 and doesn't support
18+
large files. For simplicity, it has been checked in and some bugs with handling of large files were
19+
fixed. It can be regenerated by getting Coco.jar from https://ssw.jku.at/Research/Projects/Coco and
20+
running the following command line. Note that still will overwrite any locals fixes but this should
21+
never be necessary.
22+
23+
```
24+
java -jar Coco.jar -o CompilationModel/src/main/java/at/ssw/visualizer/parser \
25+
-package at.ssw.visualizer.parser CompilationModel/src/main/java/at/ssw/visualizer/parser/CompilerOutput.atg
26+
```
27+
28+
# Releasing a new version
29+
30+
As this is now maven based, `mvn -B release:prepare` is used to update to new versions which will automatically bump the module versions.
31+
32+
The resulting zip file will be in `C1Visualizer/application/target`.
