Notes to themers and customizers
Prefix every TM scope below with source.json.comments
Level-1 customization
For insertions: keyword.operator.insertion
For special vars: variable.language.this
For escapes:
the 1st backslash in backslash-backslash is the "escaper"
the 2nd backslash in backslash-backslash is the "escapee"
for the double-escaper (defaults to comment-color): punctuation.section.insertion.escape.escaper comment.block punctuation.definition.comment.insertion.escape
for the double-escapee (defaults to normal string-color): punctuation.section.insertion.escape.escapee string.regexp.insertion.escape string.quoted.double
Level-2 customization
To highlight something in a specific area:
prefix with meta.insertion.simple to cover all characters in $var-like insertions
prefix with meta.insertion.brackets to cover all characters in ${...}-like insertions
For coloring var names (and not the $):
use custom.variable.other.normal for non-builtin vars
use variable.language.this for builtin vars
use punctuation variable.language.this to change the $ color of builtin vars
Level-3 customization
To color numeric vars differently
For simple numeric vars like $1 use meta.insertion.format.simple.numeric keyword.operator.insertion
For bracket-ed numeric vars, just use meta.insertion.brackets and then have meta.insertion.brackets meta.insertion.variable for non-numeric bracket insertions
To color $ differently
For $ in $VAR but not ${VAR:} use punctuation.section.insertion.dollar.simple keyword.operator.insertion
For $ in ${VAR:} but not $VAR use punctuation.section.insertion.dollar.brackets keyword.operator.insertion
Here are some misc other scopes:
meta.insertion.choice for ${name|a,b,c|}
