Adds ECL as a second supported implementation, specifically a statically linked ECL. This is interesting because we can create statically linked binaries, but has a few drawbacks which doesn't make it generally useful: * Loading things is very slow: The statically linked ECL only has byte compilation available, so when we do load things or use the REPL it is significantly worse than with e. g. SBCL. * We can't load shared objects via the FFI since ECL's dffi is not available when linked statically. This means that as it stands, we can't build a statically linked //web/panettone for example. Since ECL is quite slow anyways, I think these drawbacks are worth it since the biggest reason for using ECL would be to get a statically linked binary. If we change our minds, it shouldn't be too hard to provide ecl-static and ecl-dynamic as separate implementations. ECL is LGPL and some libraries it uses as part of its runtime are as well. I've outlined in the ecl-static overlay why this should be of no concern in the context of depot even though we are statically linking. Currently everything is building except projects that are using cffi to load shared libaries which have gotten an appropriate `badImplementations` entry. To get the rest building the following changes were made: * Anywhere a dependency on UIOP is expressed as `bundled "uiop"` we now use `bundled "asdf"` for all implementations except SBCL. From my testing, SBCL seems to be the only implementation to support using `(require 'uiop)` to only load the UIOP package. Where both a dependency on ASDF and UIOP exists, we just delete the UIOP one. `(require 'asdf)` always causes UIOP to be available. * Where appropriate only conditionally compile SBCL-specific code and if any build the corresponding files for ECL. * //lisp/klatre: Use the standard condition parse-error for all implementations except SBCL in try-parse-integer. * //3p/lisp/ironclad: disable SBCL assembly optimization hack for all other platforms as it may interfere with compilation. * //3p/lisp/trivial-mimes: prevent call to asdf function by substituting it out of the source since it always errors out in ECL and we hardcode the correct path elsewhere anyways. As it stands ECL still suffers from a very weird problem which happens when compiling postmodern and moptilities: https://gitlab.com/embeddable-common-lisp/ecl/-/issues/651 Change-Id: I0285924f92ac154126b4c42145073c3fb33702ed Reviewed-on: https://cl.tvl.fyi/c/depot/+/3297 Tested-by: BuildkiteCI Reviewed-by: tazjin <mail@tazj.in> Reviewed-by: eta <tvl@eta.st> |

depot
This repository is the monorepo for the community around The Virus Lounge, containing our personal tools and infrastructure. Everything in here is built using Nix.
A large portion of the software here is very self-referential, meaning that it exists to sustain the operation of the repository. This is the case because we partially see this as an experiment in tooling for monorepos.
Highlights
Services
-
Source code is available primarily through Sourcegraph on cs.tvl.fyi, where it is searchable and even semantically indexed. A lower-tech view of the repository is also available via cgit on code.tvl.fyi.
The repository can be cloned using
gitfromhttps://cl.tvl.fyi/depot. -
All code in the depot, with the exception of code that is checked in to individual
//usersfolders, needs to be reviewed. We use Gerrit on cl.tvl.fyi for this. -
Issues are tracked via our own issue tracker on b.tvl.fyi. Its source code lives at
//web/panettone/. -
Smaller todo-list entries which do not warrant a separate issue are listed at todo.tvl.fyi.
-
We use Buildkite for CI. Recent builds are listed on tvl.fyi/builds and pipelines are configured dynamically via
//ops/pipelines. -
A search service that makes TVL services available via textual shortcuts is available: atward
All services that we host are deployed on NixOS machines that we manage. Their
configuration is tracked in //ops/{modules,machines}.
