Yes, you can use these. Though since that only affects the command, if you exit_discard then you leave the user with a selection, so it might be better to just output an “unchanged” snippet incase you want to abort.

TextMate detects when a command’s output matches what’s already in the document (it does prefix/suffix match) so there should be no visible flash when replacing content with what’s already there



That is the weird thing: My command (running from the Macro):

#!/usr/bin/env ruby18 -wKU  
 
require "#{ENV['TM_SUPPORT_PATH']}/lib/escape.rb"
block = STDIN.read
if block =~ /^\{ [^\s]/
    print e_sn("{\n#{block[2..-3]}\n}") 
else
    print e_sn(block)
end


1. When I replace selected Text, or use "snippet" I get no indentation:

function() {
    const x = { number: 33 } 
}

-> 

function() {
    const x = {
number: 33
}    
}

2. When I output with insertAsSnippet, I get almost correction indentation 

function() {
    const x = { number: 33 } 
}

-> 

function() {
    const x = {
    number: 33
    }    
}

3. When I output with insertAsSnippet, but just print the block again without changes, I get more indentation than I need…

function() {
    const x = {
    number: 33
    }
}

->

function() {
    const x = {
            number: 33
        }
}
