" Vim syntax file

" Language: Ada (95)

" Other contributors: Preben Randhol.

" The formal spec of Ada95 (ARM) is the "Ada95 Reference Manual".

" For more Ada95 info, see http://www.gnuada.org and http://www.adapower.com.

" This vim syntax file works on vim 5.6, 5.7, 5.8 and 6.x.
|
||||
" It implements Bram Moolenaar's April 25, 2001 recommendations to make
|
||||
" the syntax file maximally portable across different versions of vim.
|
||||
" If vim 6.0+ is available,
|
||||
" this syntax file takes advantage of the vim 6.0 advanced pattern-matching
|
||||
" functions to avoid highlighting uninteresting leading spaces in
|
||||
" some expressions containing "with" and "use".
|
||||
|
||||
" For version 5.x: Clear all syntax items
|
||||
" For version 6.x: Quit when a syntax file was already loaded

" We'll highlight the standard exceptions, similar to vim's Python mode.
