Greetings. I saw a neat feature in another editor, and I was wondering if there was similar functionality in TextMate. If there is, I haven't found it yet and a pointer would be most appreciated.
When making a selection, I was wondering if there was some interface point that easily displayed how many characters were selected.
My use case? Constructing HTTP Requests and wishing to supply the accurate content length quickly and easily. I can imagine other use cases as well, but this is the one that I can see needing most often.
You will find the content of your selection in the TM variable TM_SELECTED_TEXT. Now is up to you, what kind of programming language do you prefer and what encoding to you need.
in bash: echo "$TM_SELECTED_TEXT" | wc -c
in Perl: length($ENV['TM_SELECTED_TEXT'])
etc.
If you have to deal with utf-8 then one solution would be to use Ruby's/Perl's split(//u) function ...
Or you can calculate the length by using the TM variables:
TM_LINE_INDEX - TM_INPUT_START_LINE_INDEX
this only works for ASCII
...
You can use 'Filter through command' Input: Selection Command: wc -c Output: Show Tool Tip
#this works for ascii
etc....
