This also involves adding a flag to constructors and case alternatives
in CExp which say whether it's a NIL or CONS. Currently, we only do this
for Prelude.List, which already has an effect, but soon I'll extend this
to work for all list-shaped things and rather than being hard coded. We
could also imagine spotting other shapes (enumerations especially) for
code generators to spot as they see fit.
This will require code generators to be fixed to recognise the new
ConInfo flag, but you can just ignore it.
Bootstrap code also updated, because we don't currently have a way of
having separate support.ss/rkt for the bootstrap and normal builds!
As a relict of the REPL output, several `<br>` tags where introduced,
where they are not needed or even permitted. This led to some spacing
issues (sometimes the docstring was closer to the next term than to the
one above that it actually described).
To counter the removed forced newlines, some extra margin is added below
each declaration.
As a side-effect, this also makes the W3 "Nu Html Checker" happy.
emacs sets the TERM variable to "dumb" and expects not to have to
handle any ANSI escape codes as a consequence. We need to patch the
renderer to unannotate the Doc in this situation.
This adds new `Int8`, `Int16`, `Int32` and `Int64` data types
to the compiler, thus working towards properly specified integer
types as discussed in #1048.
In addition, the following changes / corrections are made:
* Support casts from `Char`, `String`, and `Double` to all integer
types (and back). This fixes#1270.
* Make sure that all casts to limited-precision integers are properly
bounds checked (this was not the case so far for casts from `String`
and `Double` to `Int`)
* Add a thorough set of tests to make sure all bounds checks work
correctly for all supported casts and arithmetic operations
This means we can eliminate unused definitions from the generated code.
As usual, this doesn't make the generated code any faster, or the chez
compilation, but it's still good for tidiness and it does make the
generated scheme smaller.
Don't just have a placeholder. While this doesn't have a huge effect (if
any) on performance, it does generate smaller output for Chez to
process, and is tidier. Perhaps it's good for other back ends too, ones
that don't optimise as much as Chez does.
Only doing named functions, not higher order functions. HOFs may be
worth doing too, if we can, since this could remove lambdas and make
fewer closures.
The increment in TTC Version is necessary because otherwise there could
be inconsistencies between libraries and clients erasure properties.
WebKit seems to throw away any sequence of spaces between inline tags.
All affected places I found could be fixed by replacing single space
characters with the character U+2002 ("EN Space"), which means
almost the same thing as "normal space" (i.e. it breaks/wraps text and
has approximately the same width) but is not discarded by WebKit when
parsing the document.
If this should come up in a different place, a more thorough solution
might be needed (e.g. modifying `htmlEscape` to replace all spaces).
Checking the log categories isn't cheap because it involves parsing a
string. So, record whether we've ever set a log level. If we haven't,
there's no point in checking the string. This reduces overhead and saves
a few seconds in typechecking the Idris code base - also means we don't
have to worry so much about adding more logging if we feel we need it!
We've had these for a while, used for interface specialisation, but
they're not yet used anywhere else or properly documented. We should
document them soon, but for now, it's a useful performance boost to
always use the fast versions of pack/unpack/concat at runtime.
Also moves a couple to the prelude, to ensure that the fast versions are
defined in the same place as the 'normal' version so that the
transformation will always fire (that is, no need to import Data.String
for the transformation to work).
