1.14.0

CHANGES:

• Runtime/FFI:
  • Fix handling of eta expanded unification variables. Many thanks to
    Nathan Guermond for testing this tricky case.
  • Change Rawdata.Constants.eqc to a builtin
  • Fix Rawdata.Constants.cutc has always been a builtin
  • Fix compatibility with OCaml multicore, no more PtrMap
• API:
  • New FlexibleData.WeakMap to link unification variables with host
    data based on OCaml's Ephemeron
  • Change Conversion.extra_goals is now an extensible data type with one
    standard constructor Conversion.Unify taking two terms
  • New RawData.set_extra_goals_postprocessing can be used to
    post process the extra goals generated by an FFI call.
    One has to translate extensions to the extra_goals datatype to
    RawData.RawGoal (or Conversion.Unify), but can also take global
    actions like cancelling out useless or duplicate goals
  • Change Setup.init to take in input a ~file_resolver rather than a list
    of ~paths and a ~basedir. A custom file resolver can use some logic
    from the host application to find files, rather than an hardcoded one
  • New Parse.std_resolver building a standard resolver (based on paths)
  • Change signature of Parse.resolve_file making ?cwd explicit
• Library:
  • Better error messages in std.nth
  • declare_constraint is now variadic any prop, so that one can pass
    variables of different types as keys for the constraint. A list of variables
    (of the same type) is still supported.

1.13.8

CHANGES:

• Build:
  • link camlp5.gramlib as part of elpi.cmxs so that the plugin can be
    loaded via findlib.

v1.13.7

CHANGES:

• Compiler:
  • Fix bug in spilling when the spilled expression generates more than one
    argument.

v1.13.6

CHANGES:

• API:
  • Fix std.findall is now calling a builtin which is able to produce
    solutions which contain eigenvariables and uvars as well.
  • loc is now printed using / as a path separator also on Windows
  • loc.fields to project a loc into the file, line, etc...

v1.13.5

CHANGES:

• API:
  • New prune which can be used to prune a unification variable
  • New distinct_names which checks if a list of arguments is in the pattern
    fragment

v1.13.4

CHANGES:

• FFI: new ioargC_flex which considers flexible terms as Data

v1.13.3

CHANGES:

• Bugifx: keep the state component while_compiling even when execution is
  over, since the API to allocate a new Elpi uvar needs it and Coq-Elpi may
  call this API while translating the solution to Coq

v1.13.2

CHANGES:

• Build:
  • drop ppxfindcache
  • relax dependency on ocaml-migrate-parsetree

v1.13.1

CHANGES:

• API:
  • New gc.get and gc.set for reading and writing GC settings
  • New gc.minor
  • New gc.major
  • New gc.full
  • New gc.compact
  • New gc.stat
  • New gc.quick-stat
  • New min and max operators for the is builtin, they work on
    int and float
  • Rename rex_match -> rex.match
  • Rename rex_replace -> rex.replace
  • Rename rex_split -> rex.split
  • Rename counter -> trace.counter
• FFI:
  • New Builtin.unspec type to express optional input

v1.13.0

CHANGES:

• API:
  • Fix open_append was messing up file permissions
  • New Parse.resolve_file to find where the parser would find (or not) an
    accumulated file
  • Change signature of Compile.unit, Compile.assemble and Compile.extend
    and improve their implementation. Units are now smaller and link/relocate
    faster (making ~follows not worth it)
• CI:
  • Switch to Github actions and avsm/setup-ocaml. Now testing on Linux, MacOS
    and Windows. Artifacts produce binaries for all platforms and a benchmarks
    plot.
• Library:
  • New if2
  • New std.map-ok
  • New std.fold-map
  • New std.intersperse
  • New std.omap
  • New std.take-last
  • New std.string.concat
