LEF/DEF parser

Parses Library and Design Exchange Format (LEF/DEF) into an Abstract Syntax Tree (AST). Intended for use with LibreSilicon Compiler (lsc).

Usage

import qualified Data.Text as Text

import Language.DEF.Parser (parseDEF)
import Language.LEF.Parser (parseLEF)

main = do
  file <- Text.readFile "my.lef"
  putStrLn $ show $ parseLEF file

main = do
  file <- Text.readFile "my.def"
  putStrLn $ show $ parseDEF file

Building DEF files from AST

lefdef also allows for efficient construction of DEF files through operations on the Builder type.

import qualified Data.Text as Text
import qualified Data.Text.Lazy.IO as Lazy
import Data.Text.Lazy.Builder

import Language.DEF.Syntax
import Language.DEF.Parser (parseDEF)
import Language.DEF.Builder

main = do
  file <- Text.readFile "my.def"
  case parseDEF file of
    Left err -> putStrLn $ show err
    Right def -> Lazy.putStr $ toLazyText $ builderDEF def
