NAME
ml-nlffigen - SML No Longer Foreign Function Interface toolSYNOPSIS
ml-nlffigen [option] -- fileDESCRIPTION
This manual page documents briefly the ml-nlffigen command. This manual page was written for the Debian distribution because the original program does not have a manual page.ml-nlffigen, a glue-code generator for the new NLFFI foreign function interface. The generator reads C source code and emits ML code along with a description file for CM.
OPTIONS
A summary of options is included below.- -dir dir
- -d d
- Output directory where all generated files are placed. default: NLFFI-Generated.
- -allSU
- Instructs ml-nlffigen to include all structs and unions, even those that are defined in included files (as opposed to files explicitly listed as arguments). default: off.
- -width w
- -w w
- Sets output line width (just a guess) to w. default: 75.
- -smloption x
- Instructs ml-nlffigen to include x into the list of options to annotate .sml entries in the generated .cm file with. default: noguid.
- -guid
- Removes the default -noguid from the list of sml options. (This re-enables strict handling of type- and object-identity but can have negative impact on CM cutoff recompilation performance if the programmer routinely removes the entire tree of ml-nlffigen-generated files during development.)
- -lambdasplit x
- -ls x
- Instructs ml-nlffigen to generate "lambdasplit" options for all ML files (see CM manual for what this means; it does not currently work anyway because cross-module inlining is broken). default: nothing.
- -target t
- -t t
- Sets the target to t (which must be one of "sparc-unix","x86-unix", or "x86-win32"). default: current architecture.
- -light
- -l
- Suppress "heavy" versions of function wrappers and field accessors; also resets any earlier -heavy to default. default: not suppressed.
- -heavy
- -h
- suppress "light" versions of function wrappers and field accessors; also resets any earlier -light to default. default: not suppressed
- -namedargs
- -na
- Instruct ml-nlffigen to generated function wrappers that use named arguments (ML records) instead of tuples if there is enough information for this in the C source; (this is not always very useful). default: off.
- -nocollect
- Do not do the following: Collect enum constants from truly unnamed enumerations (those without tags that occur at toplevel or in an unnamed context, i.e., not in a typedef or another named struct or union) into a single artificial enumeration tagged by ' (single apostrohe). The corresponding ML-side representative will be a structure named E_'.
- -enum-constructors
- -ec
- When possible (i.e., if all values of a given enumeration are different from each other), make the ML representation type of the enumeration a datatype. The default (and fallback) is to make that type the same as MLRep.Signed.int.
- -libhandle h
- -lh h
- Use the variable h to refer to the handle to the shared library object. Given the constraints of CM, h must have the form of a long ML identifier, e.g., MyLibrary.libhandle.default:Library.libh.
- -include f
- -add f
- Mention file f in the generated .cm file. This option is necessary at least once for providing the library handle. It can be used arbitrarily many times, resulting in more than one such programmer-supplied file to be mentioned. If f is relative, then it must be relative to the directory specified in the -dir dir option.
- -cmfile f
- -cm f
- Specify name of the generated .cm file, relative to the directory specified by the -dir dir option. default: nlffi-generated.cm.
- -cppopt o
- The string o gets added to the list of options to be passed to cpp (the C preprocessor). The list of options gets substituted for %o in the cpp command line template.
- -U x
- The string -Ux gets added to the list of cpp options.
- -D x
- The string -Dx gets added to the list of cpp options.
- -I x
- The string -Ix gets added to the list of cpp options.
- -version
- Just write the version number of ml-nlffigen to standard output and then quit.
- -match r
- -m r
- Normally ml-nlffigen will include ML definitions for a C declaration if the C declaration textually appears in one of the files specified at the command line. Definitions in #include-d files will normally not appear (unless their absence would lead to inconsistencies). By specifying -matchr , ml-nlffigen will also include definitions that occur in recursively #include-d files for which the awk-style regular expression r matches their names.
- -prefix p
- -p p
- Generated ML structure names will all have prefix p (in addition to the usual "S_" or "U_" or "F_" ...)
- -gensym g
- -g g
- Names "gensym-ed" by ml-nlffigen (for anonymous struct/union/ enums) will get an additional suffix _g. (This should be used if output from several indepdendent runs of ml-nlffigen are to coexist in the same ML program.)
- --
- Terminate processing of options, remaining arguments are taken to be C sources.
