OMakeFlags(options)
      options : String

The OMakeFlags function is used to set omake options from within OMakefiles. The options have exactly the same format as options on the command line.

For example, the following code displays the progress bar unless the VERBOSE environment variable is defined.

    if $(not $(defined-env VERBOSE))
        OMakeFlags(-S --progress)
        export

   OMakeVersion(version1)
   OMakeVersion(version1, version2)
      version1, version2 : String

The OMakeVersion function is used for version checking in OMakefiles. It takes one or two arguments.

In the one argument form, if the omake version number is less than <version1>, then an exception is raised. In the two argument form, the version must lie between version1 and version2.

   $(cmp-versions version1, version2)
      version1, version2 : String

The cmp-versions\ functions can be used to compare arbitrary version strings. It returns 0 when the two version strings are equal, a negative number when the first string represents an earlier version, and a positive number otherwise.

   DefineCommandVars()

The DefineCommandVars function redefines the variables passed on the commandline. Variables definitions are passed on the command line in the form name=value. This function is primarily for internal use by omake to define these variables for the first time.

ROOT

The root directory of the current project.

CWD

The current working directory (the directory is set for each OMakefile in the project).

EMPTY

The empty string.

STDROOT

The name of the standard installed OMakeroot file.

VERBOSE

Whether certain commands should be verbose (false by default).

ABORT_ON_COMMAND_ERRORS

If set to true, the construction of a target should be aborted whenever one of the commands to build it fail. This defaults to true, and should normally be left that way.

SCANNER_MODE This variable should be defined as one of four values (defaults to enabled).

enabled

Allow the use of default .SCANNER rules. Whenever a rule does not specify a :scanner: dependency explicitly, try to find a .SCANNER with the same target name.

disabled

Never use default .SCANNER rules.

warning

Allow the use of default .SCANNER rules, but print a warning whenever one is selected.

error

Do not allow the use of default .SCANNER rules. If a rule does not specify a :scanner: dependency, and there is a default .SCANNER rule, the build will terminate abnormally.

INSTALL

The command to install a program (install on Unix, cp on Win32).

PATHSEP

The normal path separator (: on Unix, ; on Win32).

DIRSEP

The normal directory separator (/ on Unix, \ on Win32).

The StaticCLibrary builds a static library.

StaticCLibrary(<target>, <files>)

The <target> does not include the library suffix, and The <files> list does not include the object suffix. These are obtained from the EXT_LIB and EXT_OBJ variables.

The following command builds the library libfoo.a from the files a.o b.o c.o on Unix, or the library libfoo.lib from the files a.obj b.obj c.obj on Win32.

StaticCLibrary(libfoo, a b c)

The StaticCLibraryCopy function copies the static library to an install location.

StaticCLibraryCopy(<tag>, <dir>, <lib>)

The <tag> is the name of a target (typically a .PHONY target); the <dir> is the installation directory, and <lib> is the library to be copied (without the library suffix).

For example, the following code copies the library libfoo.a to the /usr/lib directory.

StaticCLibraryCopy(install, /usr/lib, libfoo)

The StaticCLibraryInstall function builds a library, and sets the install location in one step.

StaticCLibraryInstall(<tag>, <dir>, <libname>, <files>)

StaticCLibraryInstall(install, /usr/lib, libfoo, a b c)

These functions mirror the StaticCLibrary, StaticCLibraryCopy, and StaticCLibraryInstall functions, but they build an object file (a .o file on Unix, and a .obj file on Win32).

The CProgram function builds a C program from a set of object files and libraries.

CProgram(<name>, <files>)

The <name> argument specifies the name of the program to be built; the <files> argument specifies the files to be linked.

Additional options can be passed through the following variables.

CFLAGS

Flags used by the C compiler during the link step.

LDFLAGS

Flags to pass to the loader.

LIBS

   LIBS = libfoo$(EXT_LIB)
   CProgram(foo, bar baz)

The CProgramCopy function copies a file to an install location.

CProgramCopy(<tag>, <dir>, <program>)

CProgramCopy(install, /usr/bin, foo)

The CProgramInstall function specifies a program to build, and a location to install, simultaneously.

CProgramInstall(<tag>, <dir>, <name>, <files>)

section
   LIBS = libfoo$(EXT_LIB)
   CProgramInstall(install, /usr/bin, foo, bar baz)

   $(dependencies targets) : File Array
   $(dependencies-all targets) : File Array
   $(dependencies-proper targets) : File Array
      targets : File Array
   raises RuntimeException

The dependencies function returns the set of immediate dependencies of the given targets. This function can only be used within a rule body and all the arguments to the dependency function must also be dependencies of this rule. This restriction ensures that all the dependencies are known when this function is executed.

The dependencies-all function is similar, but it expands the dependencies recursively, returning all of the dependencies of a target, not just the immediate ones.

The dependencies-proper function returns all recursive dependencies, except the dependencies that are leaf targets. A leaf target is a target that has no dependencies and no build commands; a leaf target corresponds to a source file in the current project.

In all three functions, files that are not part of the current project are silently discarded.

One purpose of the dependencies-proper function is for ``clean'' targets. For example, one way to delete all intermediate files in a build is with a rule that uses the dependencies-proper. Note however, that the rule requires building the project before it can be deleted. For a shorter form, see the filter-proper-targets function.

    .PHONY: clean

APP = ... # the name of the target application clean: $(APP) rm $(dependencies-proper $(APP))

   $(target targets) : Rule Array
      targets : File Sequence
   raises RuntimeException

The target function returns the Target object associated with each of the targets. See the Target object for more information.

The rule function is called whenever a build rule is defined. It is unlikely that you will need to redefine this function, except in very exceptional cases.

   rule(multiple, target, pattern, sources, options, body) : Rule
      multiple : String
      target   : Sequence
      pattern  : Sequence
      sources  : Sequence
      options  : Array
      body     : Body

The rule function is called when a rule is evaluated.

multiple

A Boolean value indicating whether the rule was defined with a double colon ::.

target

The sequence of target names.

pattern

The sequence of patterns. This sequence will be empty for two-part rules.

sources

The sequence of dependencies.

options

An array of options. Each option is represented as a two-element array with an option name, and the option value.

body

The body expression of the rule.

Consider the following rule.

   target: pattern: sources :name1: option1 :name2: option2
      expr1
      expr2

This expression represents the following function call, where square brackets are used to indicate arrays.

   rule(false, target, pattern, sources,
        [[:name1:, option1], [:name2:, option2]]
        [expr1; expr2])

omake(1), omake-quickstart(1), omake-options(1), omake-root(1), omake-language(1), omake-shell(1), omake-rules(1), omake-base(1), omake-system(1), omake-pervasives(1), osh(1), make(1)
