There is a new pull request by waynevanson against master on the void-packages repository
https://github.com/waynevanson/void-packages pkg.purescript
https://github.com/void-linux/void-packages/pull/29846
[NOMERGE] New package: purescript-0.14.0
<!-- Mark items with [x] where applicable -->
#### Summary
- Adds the wonderful compiler for purescript.
- Adds a dependency for spago (https://github.com/void-linux/void-packages/issues/24682)
___Not to be merged until___:
- [ ] GHC has been updated to 8.10.4 (https://github.com/void-linux/void-packages/pull/29506)
- [ ] Commits from adding future GHC version have been removed from this git branch
- [ ] Retested against an up-to-date master containing GHC-8.10.4
#### General
- [x] This is a new package and it conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements)
#### Have the results of the proposed changes been tested?
- [ ] I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me
- [x] I generally don't use the affected packages but briefly tested this PR
<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
-->
<!--
#### Does it build and run successfully?
(Please choose at least one native build and, if supported, at least one cross build. More are better.)
- [x] I built this PR locally for my native architecture, (x86_64, GLIBC)
- [ ] I built this PR locally for these architectures (if supported. mark crossbuilds):
- [ ] aarch64-musl
- [ ] armv7l
- [ ] armv6l-musl

+Subject: [PATCH 4/7] Drop hpack, make it easier to use cabal-install (#3933)
+
+Stack offers a relatively poor developer experience on this repository
+right now. The main issue is that build products are invalidated far
+more often than they should be. cabal-install is better at this, but
+using cabal-install together with hpack is a bit awkward.
+
+Additionally, hpack isn't really pulling its weight these days. Current
+versions of stack recommend that you check your generated cabal file in,
+which is a huge pain as you have to explain to contributors to please
+leave the cabal file alone and edit package.yaml instead (the comment
+saying the file is auto-generated is quite easy to miss).
+
+Current versions of Cabal also solve the issues which made hpack
+appealing in the first place, namely:
+
+- common stanzas mean you don't have to repeat yourself for things like
+ -Wall or dependencies
+- tests are run from inside a source distribution by default, which
+ means that if you forget to include something in extra-source-files
+ you find out when you run the tests locally, rather than having to
+ wait for CI to fail
+- the globbing syntax is slightly more powerful (admittedly not quite as
+ powerful as hpack's, but you can use globs like tests/**/*.purs now,
+ which gets us close enough to hpack that the difference is basically
+ negligible).
+
+We do still need to manually maintain exposed-modules lists, but I am
+happy to take that in exchange for the build tool not invalidating our
+build products all the time.
+
+This PR drops hpack in favour of manually-maintained Cabal files,
+so that it's easier to use cabal-install when working on the compiler.
+Stack is still the only officially supported build tool though - the
+CI, contributing, and installation docs all still use Stack.
+
+Stack also works a little better now than it used to, because I think one of
+the causes of unnecessary rebuilds was us specifying optimization flags
+in the Cabal file. (Newer versions of Cabal warn you not to do this, so
+I think this might be a known issue). To ensure that release builds are
+built with -O2, I've updated the stack.yaml file to specify that -O2
+should be used.

+-- Build the binaries and libs with `stack build`
+-- Make sure that all test suites are passing. Run the test suites with `stack test`.

++ -- NOTE: Please do not edit these version constraints manually. They are
++ -- deliberately made narrow because changing the dependency versions in
++ -- use can often result in changes in the compiler's behaviour. The
++ -- PureScript compiler is an executable first and foremost, and only
++ -- incidentally a library, and supporting a wide range of dependencies is
++ -- not a goal.
++ --
++ -- These version ranges are generated from taking a Stackage snapshot and
++ -- then generating PVP-compliant bounds based on that snapshot. You can
++ -- update to a newer snapshot as follows:
++ --
++ -- 1. Remove all version constraints from this cabal file (apart from
++ -- language-javascript).
++ -- 2. Update stack.yaml as required to select a new snapshot, and check
++ -- everything builds correctly with stack.
++ -- 3. Run `stack sdist`; this will produce a source distribution including
++ -- a modified version of the cabal file, which includes bounds for all
++ -- dependencies (because of `pvp-bounds: both` in stack.yaml).
++ -- 4. Copy the version bounds from the library's build-depends section
++ -- to here.
++ --
++ -- This procedure allows us to take advantage of Stackage snapshots to
++ -- easily perform updates, while also ensuring that the compiler will be
++ -- built with (almost) the same install plan for both cabal and stack
++ -- users.
++ --
++ -- We need to be especially careful with language-javascript because it
++ -- is part of the compiler's public API; all FFI modules must be parseable
++ -- by language-javascript otherwise the compiler will reject them. It
++ -- should always be pinned to a single specific version.

+Subject: [PATCH 5/7] Fix exponential collapsing of BindingGroups (#4006)
+
+In short: When you dfs through a tree and launch the same dfs on each node then
+you go exponential.
+
+In long: I have spotted that function definitions which are big enough (see the
+added testcase) tend to blow up the memory and take extreme amount of time to
+handle.
+
+The issue was triggered particularly in the collapseBindingGroups as it was
+running a traversal through the whole AST of each declaration that on every let
+was calling the collapseBindingGroups which was running a traversal through the
+whole AST of each declaration that on every let was calling the
+collapseBindingGroups which was running a traversal through the whole AST of
+each declaration that on every let was calling the collapseBindingGroups which
+was running a traversal(...)
+
+More clearly, collapseBindingGroups used to run collapseBindingGroupsForValue
+on each AST node which was running collapseBindingGroups on every let
+expression. This was effectively forcing all inner lets to be visited twice
+which, by the fact, that each of these duplicated evaluations was running next
+two ones, was amplifying the problem leading to exponential complexity over the
+depth of a tree.
+
+Since the purpose of this function is to flatten the binding groups of the
+declarations across the whole AST, I changed the folding function for
+everywhereOnValues to simply flatten a single layer of declarations. It works
+perfectly as going deeper is already handled by everywhereOnValues.
+
+I have prepared a testcase that fails on the master branch but is successfully
+solved after the fixes.
+
+Work on this PR was funded by aeternity

+Subject: [PATCH 6/7] Support TCO for functions with tail-recursive inner
+ functions (#3958)
+
+This commit adds support for optimizing functions that contain local
+functions which call the outer function in tail position, as long as
+those functions themselves are only called from tail position, either in
+the outer function or in other such local functions.
+
+This enables hand-written mutually-tail-recursive function groups to be
+optimized, but more critically, it also means that case guards which
+desugar to use local functions don't break TCO.

There is an updated pull request by waynevanson against master on the void-packages repository
https://github.com/waynevanson/void-packages pkg.purescript
https://github.com/void-linux/void-packages/pull/29846
[NOMERGE] New package: purescript-0.14.0
<!-- Mark items with [x] where applicable -->
#### Summary
- Adds the wonderful compiler for purescript.
- Adds a dependency for spago (https://github.com/void-linux/void-packages/issues/24682)
___Not to be merged until___:
- [ ] GHC has been updated to 8.10.4 (https://github.com/void-linux/void-packages/pull/29506)
- [ ] Commits from adding future GHC version have been removed from this git branch
- [ ] Retested against an up-to-date master containing GHC-8.10.4
#### General
- [x] This is a new package and it conforms to the [quality requirements](https://github.com/void-linux/void-packages/blob/master/Manual.md#quality-requirements)
#### Have the results of the proposed changes been tested?
- [ ] I use the packages affected by the proposed changes on a regular basis and confirm this PR works for me
- [x] I generally don't use the affected packages but briefly tested this PR
<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
-->
<!--
#### Does it build and run successfully?
(Please choose at least one native build and, if supported, at least one cross build. More are better.)
- [x] I built this PR locally for my native architecture, (x86_64, GLIBC)
- [ ] I built this PR locally for these architectures (if supported. mark crossbuilds):
- [ ] aarch64-musl
- [ ] armv7l
- [ ] armv6l-musl

+Subject: [PATCH 4/7] Drop hpack, make it easier to use cabal-install (#3933)
+
+Stack offers a relatively poor developer experience on this repository
+right now. The main issue is that build products are invalidated far
+more often than they should be. cabal-install is better at this, but
+using cabal-install together with hpack is a bit awkward.
+
+Additionally, hpack isn't really pulling its weight these days. Current
+versions of stack recommend that you check your generated cabal file in,
+which is a huge pain as you have to explain to contributors to please
+leave the cabal file alone and edit package.yaml instead (the comment
+saying the file is auto-generated is quite easy to miss).
+
+Current versions of Cabal also solve the issues which made hpack
+appealing in the first place, namely:
+
+- common stanzas mean you don't have to repeat yourself for things like
+ -Wall or dependencies
+- tests are run from inside a source distribution by default, which
+ means that if you forget to include something in extra-source-files
+ you find out when you run the tests locally, rather than having to
+ wait for CI to fail
+- the globbing syntax is slightly more powerful (admittedly not quite as
+ powerful as hpack's, but you can use globs like tests/**/*.purs now,
+ which gets us close enough to hpack that the difference is basically
+ negligible).
+
+We do still need to manually maintain exposed-modules lists, but I am
+happy to take that in exchange for the build tool not invalidating our
+build products all the time.
+
+This PR drops hpack in favour of manually-maintained Cabal files,
+so that it's easier to use cabal-install when working on the compiler.
+Stack is still the only officially supported build tool though - the
+CI, contributing, and installation docs all still use Stack.
+
+Stack also works a little better now than it used to, because I think one of
+the causes of unnecessary rebuilds was us specifying optimization flags
+in the Cabal file. (Newer versions of Cabal warn you not to do this, so
+I think this might be a known issue). To ensure that release builds are
+built with -O2, I've updated the stack.yaml file to specify that -O2
+should be used.

+ When submitting a pull request, please follow the following guidelines:
+
+ - Add at least a test to `tests/purs/passing/` and possibly to `tests/purs/failing/`.
+-- Build the binaries and libs with `stack build`
+-- Make sure that all test suites are passing. Run the test suites with `stack test`.
++- Build the binaries and libraries with `stack build --fast`. The `--fast` flag is recommended but not required; it disables optimizations, which can speed things up quite a bit.

++ -- NOTE: Please do not edit these version constraints manually. They are
++ -- deliberately made narrow because changing the dependency versions in
++ -- use can often result in changes in the compiler's behaviour. The
++ -- PureScript compiler is an executable first and foremost, and only
++ -- incidentally a library, and supporting a wide range of dependencies is
++ -- not a goal.
++ --
++ -- These version ranges are generated from taking a Stackage snapshot and
++ -- then generating PVP-compliant bounds based on that snapshot. You can
++ -- update to a newer snapshot as follows:
++ --
++ -- 1. Remove all version constraints from this cabal file (apart from
++ -- language-javascript).
++ -- 2. Update stack.yaml as required to select a new snapshot, and check
++ -- everything builds correctly with stack.
++ -- 3. Run `stack sdist`; this will produce a source distribution including
++ -- a modified version of the cabal file, which includes bounds for all
++ -- dependencies (because of `pvp-bounds: both` in stack.yaml).
++ -- 4. Copy the version bounds from the library's build-depends section
++ -- to here.
++ --
++ -- This procedure allows us to take advantage of Stackage snapshots to
++ -- easily perform updates, while also ensuring that the compiler will be
++ -- built with (almost) the same install plan for both cabal and stack
++ -- users.
++ --
++ -- We need to be especially careful with language-javascript because it
++ -- is part of the compiler's public API; all FFI modules must be parseable
++ -- by language-javascript otherwise the compiler will reject them. It
++ -- should always be pinned to a single specific version.

+Subject: [PATCH 5/7] Fix exponential collapsing of BindingGroups (#4006)
+
+In short: When you dfs through a tree and launch the same dfs on each node then
+you go exponential.
+
+In long: I have spotted that function definitions which are big enough (see the
+added testcase) tend to blow up the memory and take extreme amount of time to
+handle.
+
+The issue was triggered particularly in the collapseBindingGroups as it was
+running a traversal through the whole AST of each declaration that on every let
+was calling the collapseBindingGroups which was running a traversal through the
+whole AST of each declaration that on every let was calling the
+collapseBindingGroups which was running a traversal through the whole AST of
+each declaration that on every let was calling the collapseBindingGroups which
+was running a traversal(...)
+
+More clearly, collapseBindingGroups used to run collapseBindingGroupsForValue
+on each AST node which was running collapseBindingGroups on every let
+expression. This was effectively forcing all inner lets to be visited twice
+which, by the fact, that each of these duplicated evaluations was running next
+two ones, was amplifying the problem leading to exponential complexity over the
+depth of a tree.
+
+Since the purpose of this function is to flatten the binding groups of the
+declarations across the whole AST, I changed the folding function for
+everywhereOnValues to simply flatten a single layer of declarations. It works
+perfectly as going deeper is already handled by everywhereOnValues.
+
+I have prepared a testcase that fails on the master branch but is successfully
+solved after the fixes.
+
+Work on this PR was funded by aeternity

+Subject: [PATCH 6/7] Support TCO for functions with tail-recursive inner
+ functions (#3958)
+
+This commit adds support for optimizing functions that contain local
+functions which call the outer function in tail position, as long as
+those functions themselves are only called from tail position, either in
+the outer function or in other such local functions.
+
+This enables hand-written mutually-tail-recursive function groups to be
+optimized, but more critically, it also means that case guards which
+desugar to use local functions don't break TCO.

Comment:
I took a look, and the PureScript compiler is licensed under the 3-clause BSD license, not GPLv3 or later.

Apparently, the libtinfo dependency has been removed (see https://github.com/purescript/purescript/pull/4069). The change still hasn't been released though.

<!--
If GitHub CI cannot be used to validate the build result (for example, if the
build is likely to take several hours), make sure to
[skip CI](https://github.com/void-linux/void-packages/blob/master/CONTRIBUTING.md#continuous-integration).
When skipping CI, uncomment and fill out the following section.
Note: for builds that are likely to complete in less than 2 hours, it is not
acceptable to skip CI.
-->
