Both Zsh and Bash support aliases that begin with characters also used to
indicate options to the “alias” built-in command, as long as the alias
definition is preceeded by a double dash.
This allows, e.g, for “alias -- +x=chmod +x”.
When a script specifies the shell option “nounset” as part of the shebang (e.g.,
via “#!/usr/bin/env -S zsh -u”), our initialization scripts would produce error
messages of the form:
__ETC_FOO_SOURCED: parameter not set
These messages could probably be confusing to users when running such scripts.
By providing a fall-back in the parameter expansion, we can avoid them.
This patch does not address interactive shell start-up, where such messages may
(or may not) be less problematic.
Zsh ships some rudimentary completions for programs where upstream also ships
their own completions (e.g., curl). So as not to shadow those completions, we
need to prepend to the fpath instead of appending.
Fixes#197502
Neovim does not load the user configuration when enabled through the
module, unlike when the package is added to the home or system packages
directly. I think this difference is worth mentioning in the module's
documentation, because it was confusing to some friends.
Optional functionality of AusweisApp2 requires an UDP port to be opened.
The module allows for convenient configuration and serves as documentation.

most of these are hidden because they're either part of a submodule that
doesn't have its type rendered (eg because the submodule type is used in
an either type) or because they are explicitly hidden. some of them are
merely hidden from nix-doc-munge by how their option is put together.
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
this mostly means marking options that use markdown already
appropriately and making a few adjustments so they still render
correctly. notable for nftables we have to transform the md links
because the manpage would not render them correctly otherwise.
Makes it easier to configure `rust-motd`. Currently, it takes care of
the following things:
* Creating a timer to regularly refresh the `motd`-text and a hardened
service (which is still root to get access to e.g. fs-mounts, but
read-only because of hardening flags).
* Disabling `PrintLastLog` in `sshd.conf` if the last-login feature of
`rust-motd` is supposed to be used.
* Ensure that the banner is actually shown when connecting via `ssh(1)`
to a remote server with this being enabled.
Long story short: the SSH agent protocol doesn't support telling from
which tty the request is coming from, so the the pinentry curses prompt
appears on the login tty and messes up the output and may hang.
The current trick to workaround this is informing the gnupg agent every
time you start a shell: this assumes you will run `ssh` in the latest
tty, if you don't the latest tty will be messed up this time.
The ideal solution would be updating the tty exactly when (and where)
you run `ssh`. This is actually possible using a catch-all Match block
in ssh_config and using the `exec` feature that hooks a command to the
current shell.

this renders the same in the manpage and a little more clearly in the
html manual. in the manpage there continues to be no distinction from
regular text, the html manual gets code-type markup (which was probably
the intention for most of these uses anyway).
make (almost) all links appear on only a single line, with no
unnecessary whitespace, using double quotes for attributes. this lets us
automatically convert them to markdown easily.
the few remaining links are extremely long link in a gnome module, we'll
come back to those at a later date.
we can't embed syntactic annotations of this kind in markdown code
blocks without yet another extension. replaceable is rare enough to make
this not much worth it, so we'll go with «thing» instead. the module
system already uses this format for its placeholder names in attrsOf
paths.
markdown can't represent the difference without another extension and
both the html manual and the manpage render them the same, so keeping the
distinction is not very useful on its own. with the distinction removed
we can automatically convert many options that use <code> tags to markdown.
the manpage remains unchanged, html manual does not render
differently (but class names on code tags do change from "code" to "literal").
our xslt already replaces double line breaks with a paragraph close and
reopen. not using explicit para tags lets nix-doc-munge convert more
descriptions losslessly.
only whitespace changes to generated documents, except for two
strongswan options gaining paragraph two breaks they arguably should've
had anyway.
the conversion procedure is simple:
- find all things that look like options, ie calls to either `mkOption`
or `lib.mkOption` that take an attrset. remember the attrset as the
option
- for all options, find a `description` attribute who's value is not a
call to `mdDoc` or `lib.mdDoc`
- textually convert the entire value of the attribute to MD with a few
simple regexes (the set from mdize-module.sh)
- if the change produced a change in the manual output, discard
- if the change kept the manual unchanged, add some text to the
description to make sure we've actually found an option. if the
manual changes this time, keep the converted description
this procedure converts 80% of nixos options to markdown. around 2000
options remain to be inspected, but most of those fail the "does not
change the manual output check": currently the MD conversion process
does not faithfully convert docbook tags like <code> and <package>, so
any option using such tags will not be converted at all.
- Add a module for the thunar file manager, which depends on the xfconf dbus service, and also has a dbus service and a systemd unit.
- Renames the option services.xserver.desktopManager.xfce.thunarPlugins to programs.thunar.plugins.
Qt4 is on it's way out, according to
https://github.com/NixOS/nixpkgs/pull/174634
Barco's ClickShare driver/client requires Qt4;
an update isn't in sight anywhere.
To prepare for the removal of Qt4,
the commit at hand removes the
ClickShare package and its NixOS module.
The release notes are appended with a hint about the
removal and some alternatives that might help users
that are still in need of the driver/client functionality.
Raw logs are stored in a versioned binary format and must be update with
atopconvert(1) upon atop version updates.
Failure to do so results in atop.service startup failure as I found out
the hard way after the "atop: 2.6.0 -> 2.7.1"[0] bump:
```
May 31 01:49:25 <hostname> sh[2269709]: existing file /var/log/atop/atop_20220531 has incompatible header
May 31 01:49:25 <hostname> sh[2269709]: (created by version 2.6 - current version 2.7)
May 31 01:49:25 <hostname> systemd[1]: atop.service: Main process exited, code=exited, status=7/NOTRUNNING
```
Convert logs in `ExecStartPre` and replace them iff updated.
This is to avoid changing original modification times upon every service
start and thus work against atop's log rotation (see existing
`ExecStartPre`).

network-manager-applet uses differrent naming scheme from the VPN plug-ins.
Let’s revert to the previous state, for now, to fix eval. We can do the rename later.
This reverts commit cecb014d5d.
Renaming the variable from `initScript` to `bashAndZshInitScript` makes it clearer, what it is actually used for.
Moving the fish init script right below the other call to `thefuck --alias` makes it more obvious, when one of them is different in some important way.
* Change groupId to gid to align with the rest of NixOS modules
* Add a check to the gid option to ensure it is greater than or equal
to 1000
* Use the overridden package for the wrappers
Browser Integration requires setgid and setuid programs, which needs to be done in the system configuration.
This is cleaner than the ad-hoc ways we have to set things up for platforms without a global configuration file.
hostNames being deprecated makes configuring hosts with multiple keys a
pain. including the attr name of the entry in the host name list is a
nice convenience though, so we'll retain it and clarify the
documentation on how the actual host name list for an entry is put
together.
zsh-autosuggestions supports having fallback strategies expressed
through the ZSH_AUTOSUGGEST_STRATEGY array. For example,
`ZSH_AUTOSUGGEST_STRATEGY=(history completion)`. We should also support
this.
Currently it's rather difficult to install tmux plugins. The process involves two steps:
1. Specify the correct `pkg.tmuxPlugins` package in `environment.systemPackages`
2. Adding to the configuration file to instantiate the plugin.
This commit allows the user to specify a list of plugins under `programs.tmux.plugins`.

Release notes: https://github.com/swaywm/sway/releases/tag/1.7
Notable (backward incompatible) changes:
- The default terminal changed from Alacritty to foot
Known issues:
- `swaynag` will crash when Sway 1.6.1 is still running while the Nix
package (and thus `swaynag`) is already updated to version 1.7.
- The experimental Ozone/Wayland support of Electron apps will be broken
for a while. Electron version 17 should work but the Chromium fixes
haven't yet been backported to Electron version 16.
NixOS module: programs.sway.extraPackages: The "alacritty" package was
replaced with "foot".
VM test: We switched from the OpenGL ES 2.0 renderer to Pixman. The
terminal was also changed to foot but Alacritty is still used for the
XWayland test (since foot doesn't support X11).

The module option type `nonEmptyStr` was introduced in commit
a3c5f0cba8
The tsm modules previously simply used
`strMatching ".+"` to prevent empty option strings,
but the new type is more thorough as
it also catches space-only strings.
Without this option `DefaultSearchProviderSearchURL` and
`DefaultSearchProviderSuggestURL` are really wastefull as it does not
set search engine, at least for me.

The programs.ssh.knownHosts.*.publicKeyFile is broken, because it's
scoped to a set of host names, but to insert those host names on each
line of the file we'd have to parse out blank lines and comments, so
only the first line works. It would be much easier all round if users
just provided known hosts files in the normal format, and we pointed
ssh directly to them. This way, it would be possible to have multiple
keys for a single host (which is extremely common due to multiple
algorithms being commonplace).
We add an option for this instead of relying on extraConfig, because
we need to make sure /etc/ssh/ssh_known_hosts is always included to
ensure programs.ssh.knownHosts keeps working.
/etc/ssh/ssh_known_hosts2 is another OpenSSH default that seems a bit
weird, but there's no real reason to change that so we'll leave it.
link to search.nixos.org instead of pulling package metadata out of pkgs. this
lets us cache docs of a few more modules and provides easier access to package
info from the HTML manual, but makes the manpage slightly less useful since
package description are no longer rendered.
most modules can be evaluated for their documentation in a very
restricted environment that doesn't include all of nixpkgs. this
evaluation can then be cached and reused for subsequent builds, merging
only documentation that has changed into the cached set. since nixos
ships with a large number of modules of which only a few are used in any
given config this can save evaluation a huge percentage of nixos
options available in any given config.
in tests of this caching, despite having to copy most of nixos/, saves
about 80% of the time needed to build the system manual, or about two
second on the machine used for testing. build time for a full system
config shrank from 9.4s to 7.4s, while turning documentation off
entirely shortened the build to 7.1s.
I had trouble getting programs.firejail.wrappedBinaries to have any effect on my
system (#152852), because I did not realise that "put[ting] the actual
application binary in the global environment" included adding the program
package to environment.systemPackages, and I thought that the package must be
present for this option to take effect. I have added a clarifying parenthetical
statement explicitly mentioning environment.systemPackages in this caveat.
Previously, this was only implicitly enabled if xserver.enable = true.
However, Wayland-based desktops do not require this, and so configuring
SSH_ASKPASS on a Wayland desktop becomes cumbersome. This simplifies
that by adding a new option that defaults to the old conditional.
easiest way to do this is to move the default expression out and
abstract over what is substituted into it, using a dependent value for
the default and a descriptive value for defaultText
some options have default that are best described in prose, such as
defaults that depend on the system stateVersion, defaults that are
derivations specific to the surrounding context, or those where the
expression is much longer and harder to understand than a simple text
snippet.
bcc doesn't really need kernel itself, it just cares about module path.
It's actually better to use /run/booted-system/kernel-modules/lib/modules
for two reasons:
- no need to rebuild bcc for each new kernel
- can use a newer bcc with a booted kernel that doesn't match the current
system
* less: enable by default and set LESS=-R via lesskey
* since we set PAGER=less, programs.less.enable should default to
true.
* some programs, notably git, set a custom LESS environment if none is
present. using the lesskey mechanism to set LESS=-R lets such
programs continue to run less as they see fit.
This reverts commit 0e7b4e60a8.
* less: remove use of deprecated lesskey binary format
* less: enable in environment.nix rather than less.nix
per discussion in #139988
This module allows setting global configuration for htop in /etc/htoprc,
for example to disable showing userland threads by default
