# purescript-cst The parser for the PureScript programming language. ## Compiler compatibility We provide a table to make it a bit easier to map between versions of `purescript` and `purescript-cst`. | `purescript` | `purescript-cst` | | --- | --- | | 0.14.2 | 0.2.0.0 | | 0.14.3 | 0.3.0.0 | | 0.14.4 | 0.4.0.0 | | 0.14.5 | 0.4.0.0 | | 0.14.6 | 0.4.0.0 | | 0.14.7 | 0.5.0.0 | Before v0.14.2, there was a third package, `purescript-ast`. In v0.14.2, `purescript-ast` was merged into `purescript-cst`. | `purescript` | `purescript-cst` | `purescript-ast` | | --- | --- | --- | | 0.14.1 | 0.1.1.0 | 0.1.1.0 | | 0.14.0 | 0.1.0.0 | 0.1.0.0 |
