Release 2.7 (September 1998)

The following changes were made between release 2.6 and 2.7.

• Regular expressions were added with code taken from Perl version 5.004_04 (§ 4.9, page ).

• ASCII file I/O was added (§ 8, page ).

• The Tk widgets were removed from the Glish interpreter, and moved to a client, gtk (§ 11, page ).

• Proxy client capability was added to the Glish client library to permit moving the Tk widgets to a client (§ 15.6, page ).

• Removed warning about disgarded results.

• Removed warning about not passing functions and agents to clients.

• Added new command line options, -vi, -vf, -info, -help, and -version (§ 13.1, page ).

• $agent, $name, and $value were made local to whenever statements. This means that they are not corrupted during the processing of one whenever statement by other await or whenever statements.

• request statements now work more like await statements. They do not block all events, in their basic form, and they wait for a specific event from the client instead of just accepting the first event from the client.

• Several new functions were added:
  • tr( ), § 10.5.3, page 
  • to_upper( ), § 10.5.3, page 
  • to_lower( ), § 10.5.3, page 
  • readline( ), § 8.2, page

  • shape( ), § 10.3, page 
  • strlen( ), § 10.5.4, page

  • alloc_info( ), § 10.10, page 
  • bundle_events( ), § 10.9, page 
  • flush_events( ), § 10.9, page 
  • is_regex( ), § 4.9.7, page 
  • is_file( ), § 8.1.1, page 
  • stat( ), § 8.4, page 
  • is_asciifile( ), § 8.4, page 
  • write( ), § 8.1.3, page 
  • read( ), § 8.1.2, page 
  • fprintf( ), § 8.1.3, page 
  • printf( ), § 8.2, page 
  • sprintf( ), § 10.5.2, page 

• A few additions were made to the Tk interface:
  • popup frames were added (§ 11.1, page );
  • an event to raize a frame was added (§ 11.1, page );
  • the start, end, and resolution parameters to scale were changed from integer to float (§ 11.8, page );
  • an anchor argument (and event) was added to button, label, and message;
  • a bitmap argument (and event) was added to button (§ 11.2, page );
