" Vim syntax file for the D programming language (version 1.053 and 2.039).
"
" Language:	D
" Maintainer:	Jason Mills<jasonmills@nf.sympatico.ca>
" Last Change:	2010 Jan 07
" Version:	0.18
"
" Contributors:
"   - Kirk McDonald: version 0.17 updates, with minor modifications
"     (http://paste.dprogramming.com/dplmb7qx?view=hidelines)
"   - Jesse K. Phillips: patch for some keywords and attributes (annotations), with modifications
"   - Tim Keating: patch to fix a bug in highlighting the `\` literal
"   - Frank Benoit: Fixed a bug that caused some identifiers and numbers to highlight as octal number errors.
"
" Please email me with bugs, comments, and suggestions.
"
" Options:
"   d_comment_strings - Set to highlight strings and numbers in comments.
"
"   d_hl_operator_overload - Set to highlight D's specially named functions
"   that when overloaded implement unary and binary operators (e.g. opCmp).
"
" Todo:
"   - Determine a better method of sync'ing than simply setting minlines
"   to a large number.
"
"   - Several keywords (e.g., in, out, inout) are both storage class and
"   statements, depending on their context. Perhaps use pattern matching to
"   figure out which and highlight appropriately. For now I have made such
"   keywords storage classes so their highlighting is consistent with other
"   keywords that are commonly used with them, but are true storage classes,
"   such as lazy. Similarly, I made some statement keywords (e.g. body) storage
"   classes.
"
"   - Mark contents of the asm statement body as special
"
"   - Maybe highlight the 'exit', 'failure', and 'success' parts of the
"   scope() statement.
"
"   - Highlighting DDoc comments.
