nvs alias
nvs alias <name>
nvs alias <name> <version>
nvs alias <name> <directory>
nvs alias -d <name>
Queries, sets, or removes version aliases. When no arguments are specified, all alias names and values are listed. When just a name is specified, the value for that alias is shown, if it exists. When a name and value are specified, the alias is added or updated to the persisted list. The -d switch removes an item. The alias settings are persisted in $NVS_HOME/settings.json.
An alias may refer to a combination of a remote name and a semantic version. (Processor architectures are not aliased.) When setting an alias, the remote name may be omitted, in which case the alias refers to the default remote. For example nvs alias 6.7.0 is exactly equivalent to nvs alias default/6.7.0.
When using an alias with other commands, a processor architecture may be optionally appended to override the system default, the same as with semantic versions. For example:
$ nvs alias myalias 6.7.0
$ nvs alias
myalias default/6.7.0
$ nvs run myalias --version
v6.7.0
$ nvs which myalias
~/.nvs/node/6.7.0/x64/bin/node
$ nvs which myalias/32
~/.nvs/node/6.7.0/x86/bin/node
An alias may also refer to a local directory containing any node executable. Create an alias like this to enable NVS to switch to/from a version of node that was built locally from source:
$ nvs alias dev ~/src/node/out/Release
$ nvs use dev
PATH += ~/src/node/out/Release
$ nvs ls
#node/6.9.1/x64
>/home/username/src/node/out/Release (dev)
$ nvs use lts
PATH -= ~/src/node/out/Release
PATH += ~/.nvs/node/6.9.1/x64/bin
Note it is not possible to nvs use a directory without using an alias.
