|

For `Modula-2 <http://www.modula2.org/>`_ source code.
|
||
|
|
|
||
|
|
The Modula-2 lexer supports several dialects. By default, it operates in
|
||
|
|
fallback mode, recognising the *combined* literals, punctuation symbols
|
||
|
|
and operators of all supported dialects, and the *combined* reserved words
|
||
|
|
and builtins of PIM Modula-2, ISO Modula-2 and Modula-2 R10, while not
|
||
|
|
differentiating between library defined identifiers.
|
||
|
|
|
||
|
|
To select a specific dialect, a dialect option may be passed
|
||
|
|
or a dialect tag may be embedded into a source file.
|
||
|
|
|
||
|
|
Dialect Options:
|
||
|
|
|
||
|
|
`m2pim`
|
||
|
|
Select PIM Modula-2 dialect.
|
||
|
|
`m2iso`
|
||
|
|
Select ISO Modula-2 dialect.
|
||
|
|
`m2r10`
|
||
|
|
Select Modula-2 R10 dialect.
|
||
|
|
`objm2`
|
||
|
|
Select Objective Modula-2 dialect.
|
||
|
|
|
||
|
|
The PIM and ISO dialect options may be qualified with a language extension.
|
||
|
|
|
||
|
|
Language Extensions:
|
||
|
|
|
||
|
|
`+aglet`
|
||
|
|
Select Aglet Modula-2 extensions, available with m2iso.
|
||
|
|
`+gm2`
|
||
|
|
Select GNU Modula-2 extensions, available with m2pim.
|
||
|
|
`+p1`
|
||
|
|
Select p1 Modula-2 extensions, available with m2iso.
|
||
|
|
`+xds`
|
||
|
|
Select XDS Modula-2 extensions, available with m2iso.
|
||
|
|
|
||
|
|
|
||
|
|
Passing a Dialect Option via Unix Commandline Interface
|
||
|
|
|
||
|
|
Dialect options may be passed to the lexer using the `dialect` key.
|
||
|
|
Only one such option should be passed. If multiple dialect options are
|
||
|
|
passed, the first valid option is used, any subsequent options are ignored.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
`$ pygmentize -O full,dialect=m2iso -f html -o /path/to/output /path/to/input`
|
||
|
|
Use ISO dialect to render input to HTML output
|
||
|
|
`$ pygmentize -O full,dialect=m2iso+p1 -f rtf -o /path/to/output /path/to/input`
|
||
|
|
Use ISO dialect with p1 extensions to render input to RTF output
|
||
|
|
|
||
|
|
|
||
|
|
Embedding a Dialect Option within a source file
|
||
|
|
|
||
|
|
A dialect option may be embedded in a source file in form of a dialect
|
||
|
|
tag, a specially formatted comment that specifies a dialect option.
|
||
|
|
|
||
|
|
Dialect Tag EBNF::
|
||
|
|
|
||
|
|
dialectTag :
|
||
|
|
OpeningCommentDelim Prefix dialectOption ClosingCommentDelim ;
|
||
|
|
|
||
|
|
dialectOption :
|
||
|
|
'm2pim' | 'm2iso' | 'm2r10' | 'objm2' |
|
||
|
|
'm2iso+aglet' | 'm2pim+gm2' | 'm2iso+p1' | 'm2iso+xds' ;
|
||
|
|
|
||
|
|
Prefix : '!' ;
|
||
|
|
|
||
|
|
OpeningCommentDelim : '(*' ;
|
||
|
|
|
||
|
|
ClosingCommentDelim : '*)' ;
|
||
|
|
|
||
|
|
No whitespace is permitted between the tokens of a dialect tag.
|
||
|
|
|
||
|
|
In the event that a source file contains multiple dialect tags, the first
|
||
|
|
tag that contains a valid dialect option will be used and any subsequent
|
||
|
|
dialect tags will be ignored. Ideally, a dialect tag should be placed
|
||
|
|
at the beginning of a source file.
|
||
|
|
|
||
|
|
An embedded dialect tag overrides a dialect option set via command line.
|
||
|
|
|
||
|
|
Examples:
|
||
|
|
|
||
|
|
``(*!m2r10*) DEFINITION MODULE Foobar; ...``
|
||
|
|
Use Modula2 R10 dialect to render this source file.
|
||
|
|
``(*!m2pim+gm2*) DEFINITION MODULE Bazbam; ...``
|
||
|
|
Use PIM dialect with GNU extensions to render this source file.
|
||
|
|
|
||
|
|
|
||
|
|
Algol Publication Mode:
|
||
|
|
|
||
|
|
In Algol publication mode, source text is rendered for publication of
|
||
|
|
algorithms in scientific papers and academic texts, following the format
|
||
|
|
of the Revised Algol-60 Language Report. It is activated by passing
|
||
|
|
one of two corresponding styles as an option:
|
||
|
|
|
||
|
|
`algol`
|
||
|
|
render reserved words lowercase underline boldface
|
||
|
|
and builtins lowercase boldface italic
|
||
|
|
`algol_nu`
|
||
|
|
render reserved words lowercase boldface (no underlining)
|
||
|
|
and builtins lowercase boldface italic
|
||
|
|
|
||
|
|
The lexer automatically performs the required lowercase conversion when
|
||
|
|
this mode is activated.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
``$ pygmentize -O full,style=algol -f latex -o /path/to/output /path/to/input``
|
||
|
|
Render input file in Algol publication mode to LaTeX output.
|
||
|
|
|
||
|
|
|
||
|
|
Rendering Mode of First Class ADT Identifiers:
|
||
|
|
|
||
|
|
The rendering of standard library first class ADT identifiers is controlled
|
||
|
|
by option flag "treat_stdlib_adts_as_builtins".
|
||
|
|
|
||
|
|
When this option is turned on, standard library ADT identifiers are rendered
|
||
|
|
as builtins. When it is turned off, they are rendered as ordinary library
|
||
|
|
identifiers.
|
||
|
|
|
||
|
|
`treat_stdlib_adts_as_builtins` (default: On)
|
||
|
|
|
||
|
|
The option is useful for dialects that support ADTs as first class objects
|
||
|
|
and provide ADTs in the standard library that would otherwise be built-in.
|
||
|
|
|
||
|
|
At present, only Modula-2 R10 supports library ADTs as first class objects
|
||
|
|
and therefore, no ADT identifiers are defined for any other dialects.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
``$ pygmentize -O full,dialect=m2r10,treat_stdlib_adts_as_builtins=Off ...``
|
||
|
|
Render standard library ADTs as ordinary library types.
