The regex should match the full path for the path to be selected. Match is done with `lib.strings.match`; 129 | 130 | ```nix 131 | # import-tree.matching : regex -> import-tree 132 | 133 | import-tree.matching ".*/[a-z]+@(foo|bar)\.nix" ./some-dir 134 | ``` 135 | 136 | ### `import-tree.mapWith` 137 | 138 | `mapWith` can be used to transform each path by providing a function. 139 | e.g. to convert the path into a module explicitly. 140 | 141 | ```nix 142 | # import-tree.mapWith : (path -> any) -> import-tree 143 | 144 | import-tree.mapWith (path: { 145 | imports = [ path ]; 146 | # assuming such an option is declared 147 | automaticallyImportedPaths = [ path ]; 148 | }) 149 | ``` 150 | 151 | ### `import-tree.pipeTo` 152 | 153 | `pipeTo` takes a function that will receive the list of paths. 154 | When configured with this, `import-tree` will not return a nix module but the result of the function being piped to. 155 | 156 | ```nix 157 | # import-tree.pipeTo : ([paths] -> any) -> import-tree 158 | 159 | import-tree.pipeTo lib.id # equivalent to `.leafs` 160 | ``` 161 | 162 | ### `import-tree.leafs` 163 | 164 | `leafs` takes no arguments, it is equivalent to calling `import-tree.pipeTo lib.id`, that is, instead of producing a nix module, just return the list of results. 165 | 166 | ```nix 167 | # import-tree.leafs : import-tree 168 | 169 | import-tree.leafs 170 | ``` 171 | 172 | ## Why 173 | 174 | Importing a tree of nix modules has some advantages: 175 | 176 | ### Pattern: each file is a flake-parts module 177 | 178 | [That pattern](https://discourse.nixos.org/t/pattern-each-file-is-a-flake-parts-module/61271) was the original inspiration for publishing this library. 179 | Some of the benefits are [described in the author's personal infrastructure repository](https://github.com/mightyiam/infra#every-nix-file-is-a-flake-parts-module). 180 | 181 | ### Sharing subtrees of modules as flake parts 182 | 183 | People could share sub-trees of modules as different sets of functionality. 184 | for example, by-feature layers in a neovim distribution. 185 | 186 | ```nix 187 | # flake.nix (layered configs-distro) 188 | { 189 | outputs = _: { 190 | flakeModules = { 191 | options = {inputs, ...}: inputs.import-tree ./flakeModules/options; 192 | minimal = {inputs, ...}: inputs.import-tree [./flakeModules/options ./flakeModules/minimal]; 193 | maximal = {inputs, ...}: inputs.import-tree ./flakeModules; 194 | 195 | byFeature = featureName: {inputs, lib, ...}: inputs.import-tree.filtered (lib.hasSuffix "${featureName}.nix") ./flakeModules; 196 | }; 197 | }; 198 | } 199 | ``` 200 | 201 | Note that in the previous example, the flake does not requires inputs. 202 | That's not actually a requirement of this library, the flake *could* define its own inputs just as any other flake does. 203 | However, this example can help illustrate another pattern: 204 | 205 | ### Flakes with no inputs exposing just `flakeModules` 206 | 207 | This pattern (as illustrated by the flake code above) declares no inputs. 208 | Yet the exposed flakeModules have access to the final user's flake inputs. 209 | 210 | This bypasses the `flake.lock` advantages--`nix flake lock` wont even generate a file-- 211 | and since the code has no guarantee on which version of the dependency inputs it will run using library code will probably break. 212 | So, clearly this pattern is not for every situation, but most likely for sharing modules. 213 | However, one advantage of this is that the dependency tree would be flat, 214 | giving the final user's flake absolute control on what inputs are used, 215 | without having to worry whether some third-party forgot to use `foo.inputs.nixpkgs.follows = "nixpkgs";` on any flake we are trying to re-use. 216 | -------------------------------------------------------------------------------- /checkmate.nix: -------------------------------------------------------------------------------- 1 | # If formatting fails, run 2 | # nix run github:vic/checkmate#checkmate-treefmt 3 | # 4 | { inputs, lib, ... }: 5 | let 6 | # since we are tested by github:vic/checkmate 7 | it = inputs.target;
