Let's say I have two configuration NEON files:
parameters:
excludePaths:
- path1
includes:
- "config1.neon"
parameters:
excludePaths:
- path2
Resulting configuration (config2.neon) has only excludePath = [path2]. Is there an easy way to append the lists instead of overriding the older one? So that excludePath = [path1, path2]?
This isn't really true. Array lists like that in neon from included files are merged together as you want.
The resulting array should already be ['path1', 'path2'].
Your issue most likely lies elsewhere.
To continue, it'd be best if you opened a GitHub Discussion over at PHPStan's repository, probably with a small repository that shows what you're trying to achieve, and the problem.
The problem I was trying to solve had a different cause. Paths present in config1.neon weren't excluded not because config2.neon would overwrite the list, but because paths in config1.neon were relative to config1.neon's directory (which was different than config2.neon's directory) and didn't exist at all:
parameters:
excludePaths:
- path1 # results in /a/path1, which does not exist
includes:
- "../a/config1.neon"
parameters:
excludePaths:
- path2 # results in /b/path2
Resulting list was:
- /a/path1 # does not exist, I wanted /b/path1
- /b/path2
