Very simplistic tool to aid with updating our nixpkgs channel pins:
This tool prints the correct two `*Hashes` sets to stdout, so you can
easily delete the appropriate lines in `third_party/nixpkgs/default.nix`,
run
./bin/depot-nixpkgs-update | wl-copy
and paste it into your editor.
Doing this fully automatically would be possible, but would either
a) require changing `default.nix`, so it is regex-able more easily,
b) touching something like rnix-parser which I have no motivation to
at the moment or
c) searching for the old hashes and replacing them with the new
ones. This may be a simple and worthwhile improvement in the future.

After the discussion in #116, this stores the blob content types
in extended attributes when using the filesystem backend.
If the underlying filesystem doesn't support extended attributes,
storing blobs won't work; also, if extended attributes get removed,
blobs won't be served anymore. We can relax this behavior if
needed (i.e. log errors but still accept to store or serve blobs).
However, since the Docker Engine (and possibly other container
engines) won't accept to pull images from a registry that doesn't
use correct content types for manifest files, it could be argued
that it's better to give a hard fail. (Otherwise, the container
engine gives cryptic error messages like "missing signature key".)
I can change that behavior (and log errors but still store/serve
blobs to the filesystem) if you think it's better.
With https://github.com/google/nixery/pull/127, nixery will use extended
attributes to store metadata (when using local storage).
Right now, our integration test mounts a tmpfs to /var/cache/nixery.
However, *user* xattrs aren't supported with tmpfs [1], so setting
xattrs would fail.
To workaround this, use a folder in the current working directory and
hope it's backed by something supporting user xattrs (which is the case
for GitHub Actions).

The BAT_SYNTAXES environment variable is injected during Nix builds
and points to the build result of //third_party/bat_syntaxes, which is
included in the cheddar binary.
During development this is a bit annoying: Opening a Nix shell will
set the right variable, but it will also mess with the Cargo
environment in ways that make it annoying to use (*and* require a
pre-build of all dependencies as required by naersk).
For an easier development flow, this adds a build script that
automatically runs Nix, fetches the path to the syntax set and sets
the environment variable. It is a no-op if the variable is already
set.
This makes for a smoother development experience when working on
cheddar in a depot checkout.

* remove a step that was not supposed to be committed ("Do we have

In case the `GOOGLE_APPLICATION_CREDENTIALS` environment variable is not
set, a redirect to storage.googleapis.com is issued, which means the
underlying bucket objects need to be publicly accessible.
This wasn't really obvious until now, so further clarify it.
This copies the integration tests from `.travis.yaml` into a script,
documents the assumptions it makes, and wires it into GitHub Actions.
Contrary to the travis version, we don't use Nixery's GCS backend, as
handing out access to the bucket used, especially for PRs, needs to be
done carefully.
Adding back GCS to the integration test can be done at a later point,
either by using a mock server, or by only exposing the credentials for
master builds (and have the test script decide on whether
GOOGLE_APPLICATION_CREDENTIALS is set or not).
The previous travis version had some complicated post-mortem log
gathering - instead of doing this, we can just `docker run` nixery, but
fork it into the background with the shell - causing it to still be able
to log its output as it's running.
An additional `--rm` is appended, so the container gets cleaned up on
termination - this allows subsequent runs on non-CI infrastructure (like
developer laptops), without having to manually clean up containers.
Fixes#119.
We don't intend to label, authenticate or whatever with the
GITHUB_TOKEN, so there's not really a reason to give any broader
permissions than the defaults.
When serving a manifest, it is important to set the content-type
correctly (otherwise pulling an image is likely to give a cryptic
error message, "Error response from daemon: missing signature key").
This makes sure that we set the content-type properly for both
manifests and layers.
Adds a new internal builder that makes it possible to override the
`emacsPackages` passed to our Emacs packages, which in turn makes it
possible to inject them into the emacsPackages fixpoint and use them
with features like Emacs native compilation.

Extends storage.Persist to accept a Content-Type argument, which in
the GCS backend is persisted with the object to ensure that the object
is served back with this content-type.
This is not yet implemented for the filesystem backend, where the
parameter is simply ignored.
This should help in the case of clients which expect the returned
objects to have content-types set when, for example, fetching layers
by digest.
To ensure that registry clients which attempt to pull manifests by
their content hash can interact with Nixery, this change implements
persisting image manifests in the CAS in the same way as image layers.
In combination with the previous refactorings this means that Nixery's
serving flow is now compatible with containerd.
I have verified this locally, but CI currently only runs against
Docker and not containerd, which is something I plan to address in a
subsequent PR.
This fixes#102

This was actually executing ssh, which was kinda silly - we really just
want to check the return code of the `which` invocation

Add a script to run gerrit commands on the depot host, which reads the
gerrit username from the TVL_USERNAME env var or $(whoami) by default.
At some point this may want to solve the configuration problem in a more
general fashion, but for now this seems relatively obvious.

Adds a mechanism for per-filename overrides of the chosen language
syntax and configures it for Gerrit's submit rule file.
This also switches the syntax set used to the one from
//third_party/bat_syntaxes, which contains custom additions such as
Prolog support.

This enables half of the shortcuts for switching keyboard languages
when EXWM launches.
The cyrillic ones are commented out because Emacs doesn't start
otherwise, I've no idea why and don't care at the moment.
These records have so many fields that it's difficult to track what's
what in a long list. For convenience they're now specified in plist
format (see the example).
There isn't really a point to this because the SOA record is the one I
care the *least* about practically as Cloud DNS sets it for me, but
whatever.
vauxhall (my laptop) now has an additional screen connected at home,
but sometimes I use that screen for my desktop computer (nugget).
This refactors the randr configuration for EXWM to support somewhat
more dynamic, multi-monitor layouts and adds key bindings to toggle
between some of the different configurations I want.
Modifies notmuch-show-open-or-close-subthread to take a parameter
instead of using prefix to toggle the argument, and binds that
function to C-, and C-. in notmuch-show-mode-map to enable convenient
collapsing/uncollapsing of subthreads from point.
Configures org-journal to store journal files on camden and encrypt
them to my GPG key.
Journal entries are weekly, with weeks starting Saturday (yes, there's
a reason for this).
This uses the built-in chart.el library to create a quick graph of the
number of unread emails in each notmuch tag. Some generic tags are
excluded from the overview.
Previously, this was failing as follows:
```

Cheddar now needs to be passed the --about-filter flag to toggle the
behaviour for rendering Markdown into HTML.
By default Markdown will be highlighted like normal source code (i.e.
cgit source-filtering is the default behaviour).
This advice is potentially defined before the autoloads for telega
have run, which means that the macro-expansion fails and
`telega-ins-fmt` is looked up as a function.
With this setup the initialisation works as expected.
The lambda that acts as the sentinel for building SBCL with packages
needs to be able to capture variables if lexical binding is enabled,
which is made possible by the lexical-let form.
Adds a function that can launch Sly with a pre-configured SBCL for a
Lisp derivation in the depot.
This makes it convenient to spin up development environments for Lisp
libraries and programs by simply calling `M-x nix/sly-from-depot RET
tools.something`.
This relies on `nix-depot-path` being configured currently as I have
not yet reliably added the depot to my NIX_PATH on all machines.
Sets up Lisp modes in Sly REPL and points at the local hyperspec
checkout.
In fact the Hyperspec bit should probably be managed by Nix, but one
step at a time.
Implements support for tagging paragraphs that begin with a callout
word (TODO, WARNING, QUESTION, TIP) with an additional `cheddar-*`
class that makes it possible to render these callouts specially.
This is currently not the nicest implementation, but it works.
Since I am going down the path of adding additional Markdown
extensions it makes sense to avoid letting `format_markdown` turn into
a giant beast of a function.
Therefore this commit extracts the logic for rendering code blocks via
syntect and changes the innards of `format_markdown` to instead
provide arbitrary AST value replacements.
Instead of splitting below and moving the target buffer into the new
split, split and move the buffer into the active window.
The other way around does (for some reason I don't fully understand)
not work because `split-window-below` may return invalid windows.
Configures edwina using `s-w` as the key prefix (in line with my other
EXWM-related commands).
An additional function is added that switches to a buffer (borrowing
the implementation from `ivy-switch-buffer`) but splitting it into a
new window instead.
Implements fully static (i.e. no JavaScript!) highlighting of code
blocks when rendering Markdown.
This works by walking through the Comrak AST and replacing any code
blocks with pre-rendered HTML blocks.
Syntaxes are chosen based on the "block info", which is the string
users put after the block's opening fence. This can either be
a (case-insensitive) name of a syntax, or alternatively a file
extension associated with the desired syntax.
The theme is set to one that imitates GitHub.
Renders any ".md" file by pushing it through the Comrak rendering
pipeline.
This does not yet implement syntax highlighting of fenced blocks, but
we're getting there.
Generalises the two bits of the program that will be required either
way (extension parsing and syntax loading).
A dependency on Comrak is introduced as I think GitHub-flavoured
Markdown (with all its fancy extensions) is desirable!
This uses Nix to inject the path to the syntax highlighting assets
that ship with the bat source code into the cheddar build at compile
time, where the Rust compiler then inserts it into the binary via
macros.
bat has a lot of custom syntax highlighting definitions that they
collected from all over the place (including for languages like Nix!)
and this makes them accessible to cheddar.
Also if you're reading this, can you just take a moment to appreciate
how incredible it is that Nix just lets us do something like this?!
The first step with this tool will be to use it as a source-filter for
cgit. The second step is to use it as the Markdown renderer by
depending on one of the Markdown libraries, with integration for
rendering code snippets directly.
This moves the various projects from "type-based" folders (such as
"services" or "tools") into more appropriate semantic folders (such as
"nix", "ops" or "web").
Deprecated projects (nixcon-demo & gotest) which only existed for
testing/demonstration purposes have been removed.
(Note: *all* builds are broken with this commit)
Packages the telega-server binary and adds the required mode into
Emacs.
Unread message count is displayed in the modeline, which is neat.
Probably need to figure out some key bindings for this.
Adds an Emacs library with so far a grand total of one helper function
that can prefetch and insert a git repository at point.
This is very useful for the various Go repo imports I am doing at the
moment.
This makes it possible to quickly adjust the size of text in all
frames using one keyboard shortcut. Each of these functions
understands a prefix argument to mean "please only operate on the
current buffer", hence the following bindings and effects:
Global:
* `C-=`: Increase the global font size (chosen because `+` lies on the
`=` key)
* `C--`: Decrease the global font size
* `C-x C-0`: Restore the global default font size
Local:
* `C-u C-=`: Increase the local font size
* `C-u C--`: Decrease the local font size
* `C-u C-x C-0`: Restore the local default font size
This function makes it possible to build an Emacs instance that,
instead of launching an Emacs built by Nix, configures an Emacs
already present on the system to use the packages built by Nix.
This **requires** that the versions of the two Emacsen (i.e. the one
used by Nix to build and the one used to run the packages) are kept in
sync, otherwise byte-code incompatibilities may lead to undefined
behaviour.
