This allows for a more fine-grained control over how the traces are showed. Now users can instrument the compiler to preserve only their user-defined traces, or the only the compiler, or all, or none. We also want to add another trace level on top of that: 'compact' to only show line numbers; which will work for both user-defined and/or compiler-generated traces.
This is a *slight* hack / abuse of the code() method as we are now
doing a bit of formatting within that function. Yet, we only do so at
the very top-level (i.e. project's Error) because we can't actually
fiddle with how miette presents errors.
Also removed the 'clear' flag to do it by default instead of clogging
the terminal view.
This now works pretty nicely, and the logic is back under
`aiken_project`.
Rather than have this logic in the aiken binary, this provides a generic
mechanism to do "something" on file change events. KtorZ is going to
handle wiring it up to the CLI in the best way for the project.
I tried to write some tests for this, but it's hard to isolate the
watcher logic without wrestling with the borrow checker, or overly
neutering this utility.
- Add support to the formatter for these doc comments
- Add a new field to `Arg` `doc: Option<String>`
- Don't attach docs immediately after typechecking a module
- instead we should do it on demand in docs, build, and lsp
- the check command doesn't need to have any docs attached
- doing it more lazily defers the computation until later making
typechecking feedback a bit faster
- Add support for function arg and validator param docs in
`attach_module_docs` methods
- Update some snapshots
- Add put_doc to Arg
closes#685
The 'HEAD' call that is done to resolve package revisions from
unpinned versions is already quite cheap, but it would still be better
to avoid overloading Github with such calls; especially for users of a
language-server that would compile on-the-fly very often. Upstream
packages don't change often so there's no need to constantly check the
etag.
So we now keep a local version of etags that we fetched, as well as a
timestamp from the last time we fetched them so that we only re-fetch
them if more than an hour has elapsed. This should be fairly resilient
while still massively improving the UX for people showing up after a
day and trying to use latest 'main' features.
This means that we now effectively have two caching levels:
- In the manifest, we store previously fetched etags.
- In the filesystem, we have a cache of already downloaded zip archives.
The first cache is basically invalidated every hour, while the second
cache is only invalidated when a etag changes. For pinned versions,
nothing is invalidated as they are considered immutable.
And so, even for unpinned package. In this case, we can't do a HEAD request. So we fallback by looking at what's available in the cache and using the most recently downloaded version from the cache. This is only a best effort as the most recently downloaded one may not be the actual latest. But common, this is a case where (a) someone didn't pin any version, (b) is trying to build on in an offline setup. We could possibly make that edge-case better but, let's see if anyone ever complains about it first.
When the version isn't a git sha or a tag, we always check that we got
the last version of a particular dependency before building. This is
to avoid those awkward moments where someone try to use something from
the stdlib that is brand new, and despite using 'main' they get a
strange build failure regarding how it's not available.
An important note is that we don't actually re-download the package
when the case occurs; we merely check an HTTP ETag from a (cheap) 'HEAD'
request on the package registry. If the tag hasn't changed then that
means the local version is correct.
The behavior is completely bypassed if the version is specified using
a git sha or a tag, as here, we can assume that fetching it once it
enough (and that it can change). If a package maintainer force-pushed
a tag however, there may be discrepency and the only way around that
is to `rm -r ./build`.
