Without this, compilation fails. The comment *is* in the included Rust
file — but we only include a fraction of the file to keep the example
short. This makes it cumbersome to both show something that works in the
slides while also making it possible for the instructor to show more
complex examples.
@randomPoison, we need to make our examples simpler here: the complexity
here makes it hard to modify the files and I feel it's hard to show
during class. I would suggest splitting this up into a very basic
example (what the birthday service was) and then add 1-2 slides with
more complex samples (if necessary). Last I taught the class, I had a
hard time a) making every example compile and b) finding time to cover
everything.
I would err on the side of makings things simple and clear.
The style used in the rest of the course is _italic_ filenames, so we
should be careful to not suddenly use **bold** names.
The style is of course up for debate, but we need to ensure
consistency first.
- Add missing package declaration on the AIDL interface slide.
- Make the parcelable example more self-contained. The existing code was
referencing variables that weren't declared in the example code.
- Add a speaker note to the logging slide about explaining that the
logger implementation is only needed in binaries, and that just the log
facade is needed in libraries.
In #2153 I aimed to fix a link but broke it.
In this PR, I fix it and add
[`mdbook-linkcheck`](https://github.com/Michael-F-Bryan/mdbook-linkcheck)
to avoid future cases.
Some past fixes that could have been prevented, in addition to mine in
this PR:
* #811
* #2064
* #2146
Note:
`mdbook-linkcheck` may also check external links with a configuration
change.
It can be beneficial to check also external links from time to time. I
ran it here and found 3 broken links.
Maintainers - sorry for the lack of a preceding issue. We can discuss it
here.
Some remaining work is to fix the outdated internal links in the
translations, not done here.
Let me know what you think about the proposed contribution.
This PR completes #1502.
This is the result of running `dprint fmt` after removing `src/` from
the list of excluded directories.
This also reformats the Rust code: we might want to tweak this a bit in
the future since some of the changes removes the hand-formatting. Of
course, this formatting can be seen as a mis-feature, so maybe this is
good overall.
Thanks to mdbook-i18n-helpers 0.2, the POT file is nearly unchanged
after this, meaning that all existing translations remain valid! A few
messages were changed because of stray whitespace characters:
msgid ""
"Slices always borrow from another object. In this example, `a` has to remain "
-"'alive' (in scope) for at least as long as our slice. "
+"'alive' (in scope) for at least as long as our slice."
msgstr ""
The formatting is enforced in CI and we will have to see how annoying
this is in practice for the many contributors. If it becomes annoying,
we should look into fixing dprint/check#11 so that `dprint` can annotate
the lines that need fixing directly, then I think we can consider more
strict formatting checks.
I added more customization to `rustfmt.toml`. This is to better emulate
the dense style used in the course:
- `max_width = 85` allows lines to take up the full width available in
our code blocks (when taking margins and the line numbers into account).
- `wrap_comments = true` ensures that we don't show very long comments
in the code examples. I edited some comments to shorten them and avoid
unnecessary line breaks — please trim other unnecessarily long comments
when you see them! Remember we're writing code for slides 😄
- `use_small_heuristics = "Max"` allows for things like struct literals
and if-statements to take up the full line width configured above.
The formatting settings apply to all our Rust code right now — I think
we could improve this with https://github.com/dprint/dprint/issues/711
which lets us add per-directory `dprint` configuration files. However,
the `inherit: true` setting is not yet implemented (as far as I can
tell), so a nested configuration file will have to copy most or all of
the top-level file.

```
* removed $ from code-blocks in build_all.sh
* separate the code from the output
* added shell indicator for the code block
* added shell indicator for the code block
* update logging.md
* separate the code from the output in other files as well
* update the output code-blocks to text
