can I make a new language syntax like this ? And how can I select this as a syntax like HTML or javascript ? 

{

"description":"Code Completion for Test",

"uuid":"45F68C83-30E6-9078-DC1E-E9C422AEA5A2",

"completionSets":[

{

"name":"test.words",

"defaultAppend":"",

"strings":[

"ookk",

"fuckyou",

"hello"

]

}

],

"contexts":[

{

"description":"lalal",

"scope":"text.html - source - comment - string",

"pattern":"([a-zA-Z0-9]*)",

}

]

}
