patch 9.1.0013: Modula2 filetype support lacking
Problem: Modula2 filetype support lacking
Solution: Improve the Modula-2 runtime support, add additional modula2
dialects, add compiler plugin, update syntax highlighting,
include syntax tests, update Makefiles (Doug Kearns)

" Vim syntax file

" Language: Modula-2 (PIM)

|

" ----------------------------------------------------
|
||||
|
||||
" Remarks:
|
||||
" Vim Syntax files are available for the following Modula-2 dialects:
|
||||
" * for the PIM dialect : m2pim.vim (this file)
|
||||
" * for the ISO dialect : m2iso.vim
|
||||
" * for the R10 dialect : m2r10.vim
|
||||
|
||||
" -----------------------------------------------------------------------------
|
||||
" This syntax description follows the 3rd and 4th editions of N.Wirth's Book
|
||||
" Programming in Modula-2 (aka PIM) plus the following language extensions:
|
||||
" * non-leading, non-trailing, non-consecutive lowlines _ in identifiers
|
||||
" * widely supported non-standard types BYTE, LONGCARD and LONGBITSET
|
||||
" * non-nesting code disabling tags ?< and >? at the start of a line
|
||||
" -----------------------------------------------------------------------------
|
||||
|
||||
" Parameters:
|
||||
"
|
||||
" Vim's filetype script recognises Modula-2 dialect tags within the first 200
|
||||
" lines of Modula-2 .def and .mod input files. The script sets filetype and
|
||||
" dialect automatically when a valid dialect tag is found in the input file.
|
||||
" The dialect tag for the PIM dialect is (*!m2pim*). It is recommended to put
|
||||
" the tag immediately after the module header in the Modula-2 input file.
|
||||
"
|
||||
" Example:
|
||||
" DEFINITION MODULE Foolib; (*!m2pim*)
|
||||
"
|
||||
" Variable g:modula2_default_dialect sets the default Modula-2 dialect when the
|
||||
" dialect cannot be determined from the contents of the Modula-2 input file:
|
||||
" if defined and set to 'm2pim', the default dialect is PIM.
|
||||
"
|
||||
" Variable g:modula2_pim_allow_lowline controls support for lowline in identifiers:
|
||||
" if defined and set to a non-zero value, they are recognised, otherwise not
|
||||
"
|
||||
" Variable g:modula2_pim_disallow_octals controls the rendering of octal literals:
|
||||
" if defined and set to a non-zero value, they are rendered as errors.
|
||||
"
|
||||
" Variable g:modula2_pim_disallow_synonyms controls the rendering of & and ~:
|
||||
" if defined and set to a non-zero value, they are rendered as errors.
|
||||
"
|
||||
" Variables may be defined in Vim startup file .vimrc
|
||||
"
|
||||
" Examples:
|
||||
" let g:modula2_default_dialect = 'm2pim'
|
||||
" let g:modula2_pim_allow_lowline = 1
|
||||
" let g:modula2_pim_disallow_octals = 1
|
||||
" let g:modula2_pim_disallow_synonyms = 1
