unsafeFromHexDigest :: Text -> ByteString Source #
Decode a hex digest to a ByteString. Returns a broken digest if the decode fails - hence it being marked as unsafe.
toHexDigest :: ByteString -> Text Source #
Encode a ByteString to a hex digest.
parseFiles :: Object -> Parser [(FilePath, ByteString)] Source #
Parse files
part of a Manifest file
data UnexpectedModification Source #
Modified FilePath | Clash generated file was modified |
Added FilePath | Non-clash generated file was added |
Removed FilePath | Clash generated file was removed |

pprintUnexpectedModification :: UnexpectedModification -> String Source #
Pretty print an unexpected modification as a list item.
pprintUnexpectedModifications :: Int -> [UnexpectedModification] -> String Source #
Pretty print a list of unexpected modifications. Print a maximum of n modifications.
:: [TopEntityT] | This top entity plus all that depend on it. |
-> (BindingMap, Id) | Core expressions and entry point. Any changes in the call graph will trigger a recompile. |
-> CompiledPrimMap | Any changes in any primitive will trigger a recompile. |
-> ClashOpts | Certain options will trigger recompiles if changed |
-> UTCTime | Clash modification date |
-> FilePath | Path to manifest file. |
-> IO (Maybe [UnexpectedModification], Maybe Manifest, ByteString) | ( Nothing if no manifest file was found , Nothing on stale cache, disabled cache, or not manifest file found ) |
Reads a manifest file. Does not return manifest file if:
- Caching is disabled through
-fclash-no-cache
. - Manifest could not be found.
- Cache is stale. This could be triggered by any of the given arguments.
Raises an exception if the manifest file or any of the files it is referring to was inaccessible.
isUserModified :: FilePath -> FilesManifest -> IO [UnexpectedModification] Source #
Determines whether the HDL directory the given LocatedManifest
was found
in contains any user made modifications. This is used by Clash to protect the
user against lost work.
readManifest :: FromJSON a => FilePath -> IO (Maybe a) Source #
Read a manifest file from disk. Returns Nothing
if file does not exist.
Any other IO exception is re-raised.
serializeManifest :: Manifest -> Text Source #
Serialize a manifest.
TODO: This should really yield a ByteString
