Installation

Recommended installation is via git clone into your nodenv root, as per below. However, this plugin may also be installed via homebrew or npm. If installed outside of NODENV_ROOT, you must ensure its share/node-build directory has been added to the NODE_BUILD_DEFINITIONS path.

Installing with Git

To install, clone this repository into your $(nodenv root)/plugins directory.

$ git clone https://github.com/nodenv/node-build-update-defs.git "$(nodenv root)"/plugins/node-build-update-defs

Installing with Homebrew

$ brew install nodenv/nodenv/node-build-update-defs

Note: Requires manually adding $(brew --prefix node-build-update-defs)/share/node-build directory to NODE_BUILD_DEFINITIONS

Installation with npm

$ npm install --global @nodenv/node-build-update-defs

Note: Requires manually adding $(npm -g prefix)/lib/node_modules/@nodenv/node-build-update-defs/share/node-build directory to NODE_BUILD_DEFINITIONS

Requirements

node >= 6.0

Unlike virtually every other nodenv plugin, node-build-update-defs actually depends on node. (The scraper runs on node.) A somewhat recent version of node is required – it is recommended to configure a node-version within the plugin directory itself (substitute your chosen version):

$ cd "$(nodenv root)"/plugins/node-build-update-defs
$ nodenv local 6.0

Usage

$ nodenv update-version-defs

By default, this will create build definitions in the plugin's share/node-build/ directory. This directory can be overridden with --destination. For scraped definitions to be picked up by node-build/nodenv install, the destination directory must be present in NODE_BUILD_DEFINTIONS. See special environment variables

Only definitions that aren't already in node-build's lookup path (NODE_BUILD_DEFINITIONS) will be created. That is, under typical usage only definitions not already shipped with node-build will be created. To override this and write definitions for all available node/io versions, use --force. (This will overwrite any conflicting definition files that already exist in the destination directory.)

Special environment variables

• NODE_BUILD_DEFINITIONS can be a list of colon-separated paths that get additionally searched when looking up build definitions. The share/node-build/ directories of any plugin under $(nodenv root)/plugins are appended to this path by nodenv install automatically. Definitions already found in these paths will be skipped (unless --force).

Cleanup/Pruning

In normal operation, build definitions will gradually build up in this plugin's share/node-build directory (or elsewhere if overridden with --destination). Eventually, as the scraped definitions are added to node-build itself, these user-scraped definitions will become duplicates when their node-build installation is updated. In order to ensure one is frequently running on the "proper" build definitions from node-build, any duplicates in the plugin directory ought to be removed.

$ nodenv prune-version-defs

This subcommand removes (or lists with --dry-run) any duplicate build definitions. Like update-version-defs, --destination <dir> overrides the default value of <plugin-root>/share/node-build as the directory from which duplicates are removed. Duplicates are searched for under NODE_BUILD_DEFINITIONS and are determined by both filename and contents. The file contents check can be overridden with --force, which will delete duplicates based solely on filename.

This subcommand is silent by default, only printing removed duplicates if --verbose. (--dry-run implies --verbose)
