ProjectMill ----------- Need to generate a bunch of TileMill projects that are nearly identical and then render them all out? What to script that? We gotcha covered. ## Depends - Node.js v0.8.x or v0.10.x ## Installation ProjectMill is a node.js script that is run from the command line. To install: git clone https://github.com/mapbox/projectmill.git cd projectmill npm install ## Usage Usage: `./index.js <command> [options]` Example: `./index.js --mill --render -c config.example.json -t ../tilemill/` Note: the `-t` option can either point to a source checkout and built version of TileMill or it can point to a packaged version of TileMill. On Ubuntu it can point to the apt-get installed location of TileMill: -t /usr/share/tilemill/ On OS X the `TileMill.app` bundles its own node.js version so you first need to set your PATH export PATH=/Applications/TileMill.app/Contents/Resources/:$PATH Then you can pass the `-t` argument to point inside the TileMill.app: -t /Applications/TileMill.app/Contents/Resources/ ## Configuration Configuration is expected as a json file which contains an array as the root object. See `config.example.json` for an example. Each element in the array should be an object which can have the following keys: `source` REQUIRED The source project, generally the name of folder it lives in. `destination` REQUIRED The destination project name. `mml` A json snippet which will be merged on top of the project's mml file. To clear out an option set it to 'null' `cartoVars` A json object containing key value pairs which can be use to override variables in in carto stylesheets. `MBmeta` MBTiles: A json object containing key value pairs which will be added to a rendered MBtiles export. Additionally, the following options will be passed to TileMill's export commnd `format` Export format (png|pdf|svg|mbtiles). (Default: undefined) `bbox` Array containing coordinates of bounding box to export. (Default: undefined) `minzoom` MBTiles: minimum zoom level to export. (Default: undefined) `maxzoom` MBTiles: maximum zoom level to export. (Default: undefined) `width` Image: image width in pixels. (Default: 400) `height` Image: image height in pixels. (Default: 400) `bufferSize` Mapnik render buffer size. (Default: 128) ## Commands ProjectMill accepts the following commands. They can be issued either individually or together. `--mill` Generates new tilemill projects based on configuration. `--render` Renders projects that are present in configuration and have been milled. `--upload` Uploads projects that are present in configuration and have been rendered. ## Options -t Path to the TileMill install -c specify a configuration file. (Defaults: `./config.json`) -p Path to TileMill project folder. (Defaults: `~/Documents/Mapbox`) -f Replace existing projects (together with `mill`) or existing projects and exports (together with `render`).
