Tern layer
Table of ContentsClose
1. Description
This layer adds support for tern stand-alone code-analysis engine for JavaScript.
1.1. Features:
- TODO: list the feature of tern supported by tern package
2. Install
To use this configuration layer, add it to your ~/.spacemacs. You will need to
add tern to the existing dotspacemacs-configuration-layers list in this
file.
You can install tern globally with the following command:
$ npm install -g tern
3. Configuration
3.1. Custom tern command
Windows users may need to set the variable tern-command in order for emacs to
locate and launch tern server successfully. See this open issue for more
details. The variable can be set by adding the tern layer with this
configuration layer:
(tern :variables tern-command '("node" "/path/to/tern/bin/tern"))
Note: tern-command must be a list of strings.
3.2. Re-use the server across multiple different editing sessions
By default tern is setup to not create multiple .tern-port files in your
repository.
To make tern re-use the server across multiple different editing sessions (thus
creating multiple .tern-port files for each document you have open see here
for more details) set the variable tern-disable-port-files to nil:
(tern :variables tern-disable-port-files nil)
