Description
This module contains very basic definitions for Futhark - so basic, that they can be shared between the internal and external representation.

Documentation
data Uniqueness Source #
The uniqueness attribute of a type. This essentially indicates
whether or not in-place modifications are acceptable. With respect
to ordering, Unique is greater than Nonunique.
Constructors
| Nonunique | May have references outside current function. |
| Unique | No references outside current function. |
Instances
data NoUniqueness Source #
A fancier name for () - encodes no uniqueness information.
Also has a different prettyprinting instance.
Constructors
| NoUniqueness |
Instances
Location utilities
Source location type. Source location are all equal, which allows AST nodes to be compared modulo location information.

Minimal complete definition
Instances
locStr :: Located a => a -> String Source #
A human-readable location string, of the form
filename:lineno:columnno. This follows the GNU coding standards
for error messages:
https://www.gnu.org/prep/standards/html_node/Errors.html
This function assumes that both start and end position is in the same file (it is not clear what the alternative would even mean).
locStrRel :: (Located a, Located b) => a -> b -> String Source #
Like locStr, but locStrRel prev now prints the location now
with the file name left out if the same as prev. This is useful
when printing messages that are all in the context of some
initially printed location (e.g. the first mention contains the
file name; the rest just line and column name).
prettyStacktrace :: Int -> [Text] -> Text Source #
Given a list of strings representing entries in the stack trace and the index of the frame to highlight, produce a final newline-terminated string for showing to the user. This string should also be preceded by a newline. The most recent stack frame must come first in the list.
Name handling
The abstract (not really) type representing names in the Futhark
compiler. Strings, being lists of characters, are very slow,
while Texts are based on byte-arrays.
Instances
nameToString :: Name -> String Source #
Convert a name to the corresponding list of characters.
nameFromString :: String -> Name Source #
Convert a list of characters to the corresponding name.
A name tagged with some integer. Only the integer is used in
comparisons, no matter the type of vn.
Instances
quote :: Text -> Text Source #
Enclose a string in the prefered quotes used in error messages. These are picked to not collide with characters permitted in identifiers.
