φso\n\nA LuaLaTeX package based on\nthe [`unicode-math`][unicode_math] and [`derivative`][derivative] packages\nproviding commands to write the equations of physics\nrespecting the [ISO-80000][iso] standard.\n\n## About\n\nφso or `phiso` is a personal package\nthat I use to typeset equations in documents and presentations.\nMost of the commands are related to fluid mechanics,\nhowever the package might expand and be useful to others.\n\n## Requirements\n\nAs well as running LuaLaTex for unicode support,\nthe following package are required:\n\n- [`derivative`][derivative]\n- [`unicode-math`][unicode_math]\n\n## Package options\n\nThe package offers several options for tailoring its behavior.\nThese options can be enabled using the following:\n\n```latex\n\\usepackage[\u003coption1\u003e,\u003coption2\u003e]{phiso}\n```\n\nBelow is the enumeration of these options:\n\n- `mathtools`: load the `mathtools` package prior to `unicode-math`\n- `nablaregular`: use regular symbol (not bold) for nabla\n- `diffitalic`: use italic symbol for differential\n  (pass the `italic=true` option to `derivative`)\n\n## Installation\n\nAs a personal package,\nφso is not included in TeX Live or any other distribution.\nTo use it,\nyou have the option to download and copy the `phiso.sty` file\ninto your LaTeX document's source folder,\nor install it in your `$TEXMFHOME` directory with the following command:\n\n```shell\nwget https://github.com/loicreynier/phiso/blob/main/phiso.sty \\\n     -O \"$TEXMFHOME/phiso.sty\"\n```\n\nAfter installation,\nyou can simply load it like any other package with `\\usepackage{phiso}`.\n\n### Nix TeX Live custom package\n\nFor Nix users,\nthe flake provides a TeX Live package (`scheme-full`) available with φso\nalready installed.\nHere's an example of a flake that provides an environment\nwith this version of Tex Live:\n\n```nix\n{\n  description = \"LaTeX document\";\n\n  inputs = {\n    flake-utils.url = \"github:numtide/flake-utils\";\n    nixpkgs.url = \"github:NixOS/nixpkgs\";\n    phiso.url = \"github:loicreynier/phiso\";\n    phiso.inputs.nixpkgs.follows = \"nixpkgs\";\n  };\n\n  outputs = {\n    self,\n    flake-utils,\n    nixpkgs,\n    phiso,\n  }: let\n    supportedSystems = [\"x86_64-linux\"];\n  in\n    flake-utils.lib.eachSystem supportedSystems (system: let\n      pkgs = import nixpkgs {inherit system;};\n    in {\n      devShells.default = pkgs.mkShell {\n        buildInputs = with pkgs; [\n          phiso.packages.${pkgs.system}.texlive-phiso\n        ];\n      };\n    });\n}\n```\n\nYou can also build your own Tex Live package by adding φso\nas a package :\n\n```nix\ntexliveCustom = with pkgs;\n  (texlive.combine {\n    inherit (texlive) scheme-full; # Select your Tex Live scheme\n    pkgFilter = pkg:\n      lib.elem pkg.tlType [\n        \"run\"\n        \"bin\"\n      ];\n    phiso = {\n      pkgs = [phiso.packages.${pkgs.system}.default];\n    };\n  })\n```\n\n[derivative]: https://www.ctan.org/pkg/derivative\n[iso]: https://en.wikipedia.org/wiki/ISO/IEC_80000\n[unicode_math]:
