Trimming trailing spaces based on file type

[im-n1]

Hi there,

I love auto trimming trailing spaces but I had to turn it off because in certain file types it breaks the syntax. For instance Jade/Pug.
It would be great if I could specify where the trimming would be disabled. Something like:

files.trimTrailingWhitespaceExclude: [
    ".jade",
    ".pug",
]

Just simple extension recognition would do the job.

Thank you in advance.

@grafa Nice timing. With #1587 you should be able to this.
@sandy081 #1587 is shipping in Jan correct?

@ramya-rao-a Yes #1587 is being targetted for January. But this is scoped only to language based settings. In the above case, you can achieve this by configuring languages to file types and customizing settings per language.

For example

File association to language

.jade -> jade
.pug-> pug

Language based settings (In Settings)

"[jade]" : {
file.trimTrailingWhitespace: false
},
"[pug]" : {
file.trimTrailingWhitespace: false
}
