I like using Fish for interactivity at the terminal
I also like using VS Code.
There are times I am working in a project that requires a specific version of Node. The problem I was having was that each and every time I opened up a new terminal in VS Code, I would have to remember to switch to the correct node version. Sure I could have an
.nvmrc file, but then I would have to remember to issue
nvm use. I could have my login script automatically issue that command; however,
.nvmrc might be located in the parent directory.
Here is what I wanted:
- Upon login check to see if there is a
.nvmrcin the parent directory
- If so, load the settings there
- If not, do nothing
I discovered most of what I was after in this post by btoueg on GitHub
From that post I derived what I was looking for. First we need a
find-up by btoueg and another function that will issue the nvm use command per
.nvmrc found in our path.
function find-up --description 'Find file recursively in parent directory' set path (pwd) while test "$path" != "/" ; and not test -f "$path/$argv" set path (dirname $path) end if test -f "$path/$argv" echo "$path/$argv" else echo "" end end function nvm-use --description 'run nvm using .nvmrc in parent directory' set loaded_version (node --version) set nvmrc (find-up '.nvmrc') if test -f $nvmrc set nvmrc_version (cat $nvmrc) if test $loaded_version != $nvmrc_version nvm use --silent end end end
Then simply invoke it
I have that setup in my fish config file
~/.config/fish/config.fish. Now every time I open a new terminal in VS Code, it automatically switches to the correct version of node by looking for (and finding)
.nvmrc in a parent directory.
