The nixpkgs manual contains references to both sri hash and explicit sha256 attributes. This is at best confusing to new users. Since the final destination is exclusive use of sri hashes, see nixos/rfcs#131, might as well push new users in that direction gently. Notable exceptions to sri hash support are builtins.fetchTarball, cataclysm-dda, coq, dockerTools.pullimage, elixir.override, and fetchCrate. None, other than builtins.fetchTarball, are fundamentally incompatible, but all currently accept explicit sha256 attributes as input. Because adding backwards compatibility is out of scope for this change, they have been left intact, but migration to sri format has been made for any using old hash formats. All hashes have been manually tested to be accurate, and updates were only made for missing upstream artefacts or bugs.

# TeX Live {#sec-language-texlive}
|
|
|
|
Since release 15.09 there is a new TeX Live packaging that lives entirely under attribute `texlive`.
|
|
|
|
## User's guide {#sec-language-texlive-user-guide}
|
|
|
|
- For basic usage just pull `texlive.combined.scheme-basic` for an environment with basic LaTeX support.
|
|
|
|
- It typically won't work to use separately installed packages together. Instead, you can build a custom set of packages like this. Most CTAN packages should be available:
|
|
|
|
```nix
|
|
texlive.combine {
|
|
inherit (texlive) scheme-small collection-langkorean algorithms cm-super;
|
|
}
|
|
```
|
|
|
|
- There are all the schemes, collections and a few thousand packages, as defined upstream (perhaps with tiny differences).
|
|
|
|
- By default you only get executables and files needed during runtime, and a little documentation for the core packages. To change that, you need to add `pkgFilter` function to `combine`.
|
|
|
|
```nix
|
|
texlive.combine {
|
|
# inherit (texlive) whatever-you-want;
|
|
pkgFilter = pkg:
|
|
pkg.tlType == "run" || pkg.tlType == "bin" || pkg.pname == "cm-super";
|
|
# elem tlType [ "run" "bin" "doc" "source" ]
|
|
# there are also other attributes: version, name
|
|
}
|
|
```
|
|
|
|
- You can list packages e.g. by `nix repl`.
|
|
|
|
```ShellSession
|
|
$ nix repl
|
|
nix-repl> :l <nixpkgs>
|
|
nix-repl> texlive.collection-[TAB]
|
|
```
|
|
|
|
- Note that the wrapper assumes that the result has a chance to be useful. For example, the core executables should be present, as well as some core data files. The supported way of ensuring this is by including some scheme, for example `scheme-basic`, into the combination.
|
|
|
|
## Custom packages {#sec-language-texlive-custom-packages}
|
|
|
|
|
|
You may find that you need to use an external TeX package. A derivation for such package has to provide contents of the "texmf" directory in its output and provide the `tlType` attribute. Here is a (very verbose) example:
|
|
|
|
```nix
|
|
with import <nixpkgs> {};
|
|
|
|
let
|
|
foiltex_run = stdenvNoCC.mkDerivation {
|
|
pname = "latex-foiltex";
|
|
version = "2.1.4b";
|
|
passthru.tlType = "run";
|
|
|
|
srcs = [
|
|
(fetchurl {
|
|
url = "http://mirrors.ctan.org/macros/latex/contrib/foiltex/foiltex.dtx";
|
|
hash = "sha256-/2I2xHXpZi0S988uFsGuPV6hhMw8e0U5m/P8myf42R0=";
|
|
})
|
|
(fetchurl {
|
|
url = "http://mirrors.ctan.org/macros/latex/contrib/foiltex/foiltex.ins";
|
|
hash = "sha256-KTm3pkd+Cpu0nSE2WfsNEa56PeXBaNfx/sOO2Vv0kyc=";
|
|
})
|
|
];
|
|
|
|
unpackPhase = ''
|
|
runHook preUnpack
|
|
|
|
for _src in $srcs; do
|
|
cp "$_src" $(stripHash "$_src")
|
|
done
