The path field wasn't used in DrvWithOutput as we only ever needed
rendered. rendered however is a bit of a confusing name as it is not in
fact fully rendered in all cases. Since we can pass rendered to
nix-store --realise without preprocessing in all cases we rename it to
path and add a note in the documentation. The old path field is removed
for this without replacement.

Previously, we would always assume section 1 was requested if no section
was given on the command line. Now the section is treated as if it was
unknown and we search for a matching man page by looking through the sub
directories of $output/share/man.
This means the following invokation works as expected:
nman libunwind unw_getcontext
instead of requiring
nman libunwind 3 unw_getcontext
|
|
|
|
|

temp is essentially the old TempDir code from nman, but using libc's
mkdtemp(3) directly instead of mktemp(1) and a slightly better API.

Most notably stderr produced by nix-instantiate and nix-store will now
be printed on an error.

man pages are usually pretty small and therefore often also included in
out whereas doc seems to seldomly contain any man pages.

nix-instantiate unfortunately prints the plain .drv path for <attr>.out
wheras it prints <name>.drv!<output> for all non-default outputs. If we
realise the plain .drv path, _all_ outputs are realised which is not
desireable since we may not need extra store path being created by this,
e. g. for a derivation with outputs = [ "out" "lib" "dev" ] we only need
to realise "out" if the man pages are located in there, saving a bit of
time and disk space.
We implement this better behavior by adding the render function to
DrvWithOutput which converts a DrvWithOutput (at the cost of copying) to
an OsString. If the output is out, "!out" is appended to the path
meaning nix-store will only realise the default output.

* make exit code determination nicer syntactically by using an impl
* add .msg() function which returns an appropriate error message for
every error type.

Unfortunately, nix-instantiate prints only the drv path for the `out`
output which causes nix-store to realise all drv outputs. This of course
breaks build_man_page since it expects the output to be just one path.
We fix this (for now) by using split(). Ideally we would use
<drv_path>!out for realising the default output which only builds the
output we need. However this is a bit annoying to solve since it means
we have to allocate a bit of memory.

This is a complete and user interface compatible rewrite of nman.go in
Rust which aleviates a few flaws of the previous implementation:
* Garbage collector roots for both the derivation and the build outputs
are created in a temporary directory which is cleaned afterwards. This
prevents a race condition between nman and nix-store --gc and doesn't
pollute the user's working directory.
* Instead of building just one build output, nman now checks every
output for the requested man page which fixes nman for derivations
which have their man pages split between multiple outputs, e. g. man
and devman.
Future work:
* Improve error messages reported to the user
* Man page
* Implement man page search heuristics if no section is specified:
Instead of falling back to section 1, all sections should be checked
for the desired page (in an ascending order?)

testRustSimple builds and runs the tests of a buildRustCrate derivation
automatically using drvSeqL, returning its non-test variant.
Really looking forward to pkgs.tvl :)

Small wrapper around duplicity to restore/create my backups with.
The legosi backup is created by `services.duplicity`, but can be
restored from the script via the read-only application key.

sway needs opengl driver's to be enabled and loadable in order to start.
I previously didn't notice this oversight as I still had them loaded and
did not reboot after the rebuild.

This fixes the build of pkgs.profpatsch.watch-server, it was likely only

skarnet thought it would be wise to completely change the skalibs
exec function interface without any backwards compat, so here we are.
Have to reverse the code a bit, because `xmexec0` is a recursive
`#define` pointing to `xmexec0_af`.
`record-get` gets a rust treatment, it doesn’t really need the C
interface just to exec into prog.

Small tool which takes a block of nix options that should produce a
script to run, and then calls the script with the rest of argv
e nix-run { -A foobar } a b c
calls `nix-build -A foobar && ./result a b c`.

This is a working PoC of specifying module configs as toml
configuration with simple to understand semantics.
Both the option definitions and the actual config values can be
specified via the toml DSL.
This is extremely happy-path for now, so errors are gonna be horrible.

Since the goal of using `e` with argv is interactive execution of
block-style commands from the command line, the use of { and } for
blocks is sub-optimal, since bash (and ostensibly also fish) interpret
them as metacharacters and assign some semantics.
[ and ] on the other hand are not taken (apart from the `[`
executable, which is only relevant in command position and can always
be replaced by the `test` command). So we translate a stand-alone "["
argument to "{" and the same for "]"/"}", giving us a transparent
block syntax.

Often times I want to execute “block-style” programs directly, but it
is rather inconvenient to type out `execlineb -c "…"` every time, plus
-c wants the argv as a single string instead of an argv.
The alternative, using the block representation with leading spaces,
is even less ergonomic.
So instead of
execlineb -c "nix-run { -A pkgs.profpatsch.e ~/vuizvui } echo hello"
or even
nix-run ' -A' ' pkgs.profpatsch.e' ' /home/me/vuizvui' '' echo hello
I can now write
e nix-run { -A pkgs.profpatsch.e ~/vuizvui } echo hello
and it will work as expected (provided your shell expands inside {}
blocks, which bash does but fish doesn’t for some reason).
If no argument is passed, e falls back to opening a shell prompt.

The tex sources are in a different place currently, planning to move
them here once I’ve nixified them sometime in the future.

It was only used for a single use-case, by now all browsers support
this functionality. It’s a pretty heavy dependency for a single use :)

I’ve been expanding the list somewhat, it’s time to put them on the

- clearsign

Those tell the browser that it’s going to need them later, even it
hasn’t found them yet (e.g. the fonts can only be found after loading
the CSS).

I'm not familiar with the "easy-dhall-nix" project, but the repository
is imported into Vuizvui via import-from-derivation. While this by
itself is not a big issue (apart from contributing hugely to evaluation
time, we're already at around an hour), the "dhall-nix" derivation is in
turn imported again via importDhall, so whenever something breaks with
dhall-nix, our evaluation will break as well.
Unfortunately, something is broken right now:

The reason why this happens is because GitHub's tarballs are not
deterministic and whenever GitHub changes something in the way these are
generated, we get a hash mismatch.
For exactly that reason, the fetchFromGitHub wrapper in nixpkgs uses
fetchzip instead of fetchurl, so that file ordering in the archive
doesn't matter.
Unfortunately, the upstream project still uses fetchurl, but since the
URLs and hashes have changed due to a bump to Dhall version 1.33.1, I've
choosen to switch to latest master instead of monkeypatching via
extraPostFetch.
With this bandaid, we shouldn't run into a hash collision until either
the next GC or until the upstream project has switched to either
fetchFromGitHub or fetchzip.

I want to be able to open http(s) links that are e.g. images directly
in the right application. Aka web urls should be transparent, instead
of always opening everthing in the browser.
This adds some silly ways of connecting to the server and parsing
out the headers, in order to fetch the content-type.
