Vistasvscode snippets: How to link a position in the snippet to a tabstop?
I want to create a snippet that prints the value of a variable for debugging purposes. this is what I came up with:
{
"Debug": {
"prefix": ["db"],
"body": ["console.log(\"$1 :\", $1)"]
}
}
When I use this snippet cursor goes between the quotes ( | is the cursor position):
console.log("| :",)
And after I typed the name of a variable it copies the name to the second parameter:
console.log("name :", name)
But I can't use autocompletion in strings. sometimes the variable is an object and auto-completion helps me pick a specific key of the object. I want the cursor to stop in the second parameter so I can use autocompletion:
console.log(" :", |)
And whatever I type should be copied inside the double-quotes:
console.log("name :", name)
just like the previous example but backward.
How can I do that?
UPDATE: I created an issue: https://github.com/microsoft/vscode/issues/142327

I tried with the following version:
{
"Debug": {
"prefix": ["db"],
"body": ["console.log(\"${2:$1} :\", $1);$0"]
}
}
It starts at $1, but immediately also shows the text for $2, with TAB I can change the text between double quotes but I do not get auto-completion for $1.
I think this should be asked in an issue on the repo. $2 should copy text of $1 after the TAB and $1 should have auto-completion like it does when using
{
"Debug": {
"prefix": ["db"],
"body": ["console.log(\"$2 :\", $1);$0"]
}
}

I assume you have Editor > Suggest: Snippets Prevent Quick Suggestions disabled and
"editor.quickSuggestions": {
"other": true,
"comments": true,
"strings": true // the important one here
},
In my testing even with those settings it still doesn't work. That does look like a bug. It fails even on the simpler case "\"$1\" $1". So something about being in a string is preventing intellisense despite the settings above.
But there is a workaround:
"Debug": {
"prefix": ["db"],
"body": [
// select everything you want to surround with quotes
"console.log(${2:$1 :}, $1)" // you will get intellisense
]
}
The ${2:...} will select the result of tabstop 1 + : and then you can hit " to surround that selection with quotes. You just have to hit one more tab then you might be expecting.
