— Program: haco [options] source object

Compile HAC source to object file.

— User Option: -h

Show usage and exit.

— User Option: -I path

Adds include path path for importing other source files (repeatable).

— User Option: -d

Produces text dump of compiled module, like hacobjdump in Objdump.

— User Option: -f optname

general compile flags (repeatable) where optname is one of the following:

• dump-include-paths: dumps -I include paths as they are processed
• dump-object-header: (diagnostic) dumps persistent object header before saving
• no-dump-include-paths: suppress feedback of -I include paths
• no-dump-object-header: suppress persistent object header dump
• case-collision=[ignore|warn|error]: Set the error handling policy for case-insensitive collisions.
  • ignore skips the check altogether
  • warn issues a warning but continues
  • error rejects and aborts compiling
• unknown-spec=[ignore|warn|error]: Sets the error handling policy for unknown spec directives.

Dialect flags (for ACT-compatibility):

• export-all: Treat all definitions as exported, i.e. no export checking.
• export-strict: Check that definitions are exported for use outside their respective home namespaces (default, ACT).
• namespace-instances Allow instance management outside global namespace (default). Negatable with no- prefixed. ACT mode: no-namespace-instances.
• array-internal-nodes Allow implicit arrays of internal nodes in PRS (default). Negatable with no- prefixed. ACT mode: no-array-internal-nodes.

ACT is a preset that activates all ACT-mode flags for compatibility.

The following options are forwarded to the create-phase of compilation by the driver. That is, they do not have any affect until the create phase. These options must be specified up-front at compile-time and cannot be overriden at create-time on the command line.

• canonical-shortest-hier: Only consider hierarchical depth (number of member-dots) for choosing canonical alias, no further tiebreaker.
• canonical-shortest-length: In addition to minimizing the hierarchy depth, also use overall string length as a tiebreaker.
• canonical-shortest-stage: (unimplemented) Considers length of identifiers stage-by-stage when hierarchical depths are equal. This is for best compatibility with ACT mode.

— User Option: -M depfile

Emit import dependencies in file depfile as a side-effect. Useful for automatic dynamic dependency-tracking in Makefiles.

— User Option: -o objfile

Names objfile as the output object file to save. This is an alternative to naming the object file as the second non-option argument.

— User Option: -p

Expect input to be piped from stdin rather than a named file. Since the name of the input file is omitted in this case, the only non-option argument (if any) is interpreted as the name of the output object file.

— User Option: -v

Show version and build information and exit.
