New subject: Discussion: TextMate.save_if_untitled and TextMate::Executor.run -> version

29 Sep 2014


      Hi,
I'm developing a new bundle for a scripting language. For the "Run" command I'd like to make usage of TM's TextMate::Executor library. Fine.
But I was confronted with two subjects for a discussion:
1) TextMate.save_if_untitled
In order to use TextMate::Executor one should execute "TextMate.save_if_untitled('foo')" in beforehand. But I'd like to allow to the user that s/he runs either the entire document or only a selection. With the current implementation this doesn't work, so I suggest the following change (adding of the first 6 lines of code and a new argument):
save_current_document.rb line: 33ff
def save_if_untitled(temp_ext='tmp', ignore_selection=true)
      if not ignore_selection and not ENV['TM_SELECTED_TEXT'].nil?
        ENV['TM_FILEPATH']       = nil
        if not ENV['TM_SELECTED_TEXT'].nil?
          ENV['TM_DISPLAYNAME']   += ' (Selection)'
        end
      end
      return unless ENV['TM_FILEPATH'].nil?
ENV['TM_FILEPATH']         = TextMate::IO.tempfile(temp_ext).path
      ENV['TM_FILENAME']         = File.basename(ENV['TM_FILEPATH'])
      ENV['TM_FILE_IS_UNTITLED'] = 'true'
begin
......
This approach does't break the default behaviour. Only if the developer would like to add that functionality s/he has only set the second argument to "false". By adding "(Selection)" or whatever to TM_DISPLAYNAME the user will be notified additionally.
2) TextMate::Executor.run -> version
The interpreter I'm working with is an "hybrid". If you start it without arguments or with arguments which can't be interpreted as a file name the interpreter starts in the GUI mode, i.e. a real application with windows etc. pops up. Otherwise, if you pass as first argument a valid file path plus optional arguments, the interpreter works like Perl, Python, etc. in a command line mode.
The current TextMate::Executor.run implementation has a nice feature, you can get the current version number from the current installed interpreter or compiler as default BUT you are NOT able to avoid it.
In my case the interpreter doesn't catch these kind of querying, in other words I can set the ":version_*"-options to whatever the GUI is popping up and tells me stories about errors. Finally I ended up to write a special script which returns the version number and I call it via:
:version_args => ENV["TM_BUNDLE_SUPPORT"] + "/bin/version.praat"
but I believe one could solve this kind of problem quite easily, namely if the developer sets explicitly ":version_args => nil" the version querying won't be executed. To achieve that one has to change one single line:
executor.rb line: 99
version = (not options[:version_args].nil?) ? parse_version(args[0], options) : ''
Did I miss something?
Kind regards,
Hans
