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)

|
|
" Remarks:
|
|
" Vim Syntax files are available for the following Modula-2 dialects:
|
|
" * for the PIM dialect : m2pim.vim
|
|
" * for the ISO dialect : m2iso.vim (this file)
|
|
" * for the R10 dialect : m2r10.vim
|
|
|
|
" -----------------------------------------------------------------------------
|
|
" This syntax description follows ISO standard IS-10514 (aka ISO Modula-2)
|
|
" with the addition of the following language extensions:
|
|
" * non-standard types 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 ISO dialect is (*!m2iso*). It is recommended to put
|
|
" the tag immediately after the module header in the Modula-2 input file.
|
|
"
|
|
" Example:
|
|
" DEFINITION MODULE Foolib; (*!m2iso*)
|
|
"
|
|
" 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 'm2iso', the default dialect is ISO.
|
|
"
|
|
" Variable g:modula2_iso_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_iso_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_iso_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 = 'm2iso'
|
|
" let g:modula2_iso_allow_lowline = 1
|
|
" let g:modula2_iso_disallow_octals = 1
|
|
" let g:modula2_iso_disallow_synonyms = 1
