This adds a for statement which is used to iterate over a list with a
body of statements. This is an important data transformation tool which
should be used sparingly, but is important to have.
An import statement inside of a for loop is not currently supported. We
have a simple hack to detect the obvious cases, but more deeply nested
scenarios probably won't be caught, and you'll get an obscure error
message if you try to do this.
This was incredibly challenging to get right, and it's all thanks to Sam
for his brilliance.

Instead of constantly making these updates, let's just remove the year
since things are stored in git anyways, and this is not an actual modern
legal risk anymore.
This adds a new util package with some useful functionality which could
be implemented as pure mcl, but instead we add it here as a good place
to help with code reuse.
This makes tar archives from a list of files and/or directories. It
correctly includes empty directories as well. The code structure is
similar to the gzip resource. While this resource is arguably more
useful than gzip, it was invaluable to write the gzip resource first
since that made writing this one much easier.
This may have lots of uses, particularly for bootstrapping and handoff
if we want to compress payloads. It is also a good model resource for
how to implement such a resource to avoid re-computing the result on
every CheckApply call. Of course if the computation is cheaper than the
hashing of the data this isn't the optimal approach.
This gives us a function to return a created vardir folder. It is not
locally namespaced, and a future function will have to namespace one to
each scope.
If you had ambiguous code, and specified an invalid type, this could
sneak through and become a runtime error, instead of a compile-time
error. We fix this and add a test.
I think the mgmt lib approach is a good idea, even though I'm not
putting much energy into keeping these up to date. Let's at least
re-enable the tests for now, after a few fixups.
This adds the ability to offer a dhcp lease to someone when we don't
know their mac address in advance.
This also uses the extended autogrouping API to keep the internal API
simpler.
This adds a standard gate that prevents execution if a file exists. Of
note, this also adds a watch on it, so we can have a proper watched exec
resource without a watch cmd.
With the recent merging of embedded package imports and the entry CLI
package, it is now possible for users to build in mcl code into a single
binary. This additional permission makes it explicitly clear that this
is permitted to make it easier for those users. The condition is phrased
so that the terms can be "patched" by the original author if it's
necessary for the project. For example, if the name of the language
(mcl) changes, has a differently named new version, someone finds a
phrasing improvement or a legal loophole, or for some other
reasonable circumstance. Now go write some beautiful embedded tools!
The new version of the urfave/cli library is moving to generics, and
it's completely unclear to me why this is an improvement. Their new API
is very complicated to understand, which for me, defeats the purpose of
golang.
In parallel, I needed to do some upcoming cli API refactoring, so this
was a good time to look into new libraries. After a review of the
landscape, I found the alexflint/go-arg library which has a delightfully
elegant API. It does have a few rough edges, but it's otherwise very
usable, and I think it would be straightforward to add features and fix
issues.
Thanks Alex!
I'm currently refactoring the CLI code. Unfortunately this means a
pretty big churn in the various GAPI frontends. Since nobody is actively
using the puppet frontend code, I'm removing it for now. If someone is
actively using it, and wants to either port it to the new API, or
sponsor the porting of it to the new API, I'm happy to allow it back in.
Sorry Felix, it was a fun idea, and I loved seeing it work, but I can't
personally afford the maintenance cost of having this in right now.
This adds a new caching http proxy resource that can be autogrouped into
the core http:server resource, and which caches and serves files that it
received from a different http server. It first pulls them down when
they are initially requested, which makes it possible for us to use this
for provisioning a Linux installation without having to pre-rsync the
entire package repository.
This adds a new http:flag resource which can autogroup into an
http:server resource to receive actions from client HTTP requests, and
forward these values on to other resources.
Previously the resource could only set values in a per-hostname
namespace, but for single, user-managed values, we'd like to be able to
control things entirely. Now this resource can do that.
