# News {#sec-news}
|
|
|
|
Home Manager includes a system for presenting news to the user. When
|
|
making a change you, therefore, have the option to also include an
|
|
associated news entry. In general, a news entry should only be added for
|
|
truly noteworthy news. For example, a bug fix or new option does
|
|
generally not need a news entry.
|
|
|
|
If you do have a change worthy of a news entry then please add one in
|
|
[`news.nix`](https://github.com/nix-community/home-manager/blob/master/modules/misc/news.nix)
|
|
but you should follow some basic guidelines:
|
|
|
|
- The entry timestamp should be in ISO-8601 format having \"+00:00\"
|
|
as time zone. For example, \"2017-09-13T17:10:14+00:00\". A suitable
|
|
timestamp can be produced by the command
|
|
|
|
``` shell
|
|
$ date --iso-8601=second --universal
|
|
```
|
|
|
|
- The entry condition should be as specific as possible. For example,
|
|
if you are changing or deprecating a specific option then you could
|
|
restrict the news to those users who actually use this option.
|
|
|
|
- Wrap the news message so that it will fit in the typical terminal,
|
|
that is, at most 80 characters wide. Ideally a bit less.
|
|
|
|
- Unlike commit messages, news will be read without any connection to
|
|
the Home Manager source code. It is therefore important to make the
|
|
message understandable in isolation and to those who do not have
|
|
knowledge of the Home Manager internals. To this end it should be
|
|
written in more descriptive, prose like way.
|
|
|
|
- If you refer to an option then write its full attribute path. That
|
|
is, instead of writing
|
|
|
|
The option 'foo' has been deprecated, please use 'bar' instead.
|
|
|
|
it should read
|
|
|
|
The option 'services.myservice.foo' has been deprecated, please
|
|
use 'services.myservice.bar' instead.
|
|
|
|
- A new module, say `foo.nix`, should always include a news entry that
|
|
has a message along the lines of
|
|
|
|
A new module is available: 'services.foo'.
|
|
|
|
If the module is platform specific, e.g., a service module using
|
|
systemd, then a condition like
|
|
|
|
``` nix
|
|
condition = hostPlatform.isLinux;
|
|
```
|
|
|
|
should be added. If you contribute a module then you don't need to
|
|
add this entry, the merger will create an entry for you.
