In developing my bundle, I've been issuing feedback to the user with Create New Document. Now that things are working decently, I want to switch to Show As HTML. Here's the problem. Throughout my routines, when I want to issue some feedback, I just say "puts". Now, however, using Show As HTML, I want to wrap this in some way such that every time there is a "puts" I grab it, shove a <br> on the end, and pass it along, so that my output appears streaming into the HTML window as the script runs.
So, yeah, I could look thru all my code, find every "puts", and append the <br> myself. But I don't want to. I want to just wrap up what I'm already doing and perform the transformation as the input appears. There must be some simple way to do this.
Here's what I have so far:
def self.perform(command_name, *args) require "#{ENV["TM_SUPPORT_PATH"]}/lib/web_preview.rb" STDOUT.sync = true html_header(command_name.to_s) puts "<pre>" self.send(command_name, *args) # FIX ME puts "</pre>" html_footer() end
It's that "self.send" line that I want to wrap up in some way so that I can intercept the output from each "puts" within my routines and modify it.
Solved this in a hacky way by interposing an object that masquerades as $stdout and intercepts and modifies output before passing it along to the real stdout. But I'm hoping someone will tell me there's already a simpler built-in way to do this in TextMate.
Oh, and while we're up: is there a way I can detect whether we are currently set to Create New Document or Show As HTML? I'd like to funnel all my commands thru this one bottleneck but NOT do all that stuff if we are set to Create New Document (in that case I just want to pass the output thru untouched).
Have not solved this one yet. Hints appreciated. m.
