Usually, a build action is -a construction command, that is, a command-line string that invokes -an external command. Cons can also execute Perl code embedded in a -command-line string, and even supports an experimental ability to build -a target file by executing a Perl code reference directly. - -A build action is usually specified as the value of a construction -variable: - - $env = new cons( - CCCOM => '%CC %CFLAGS %_IFLAGS -c %< -o %>', - LINKCOM => '[perl] &link_executable("%>", "%<")', - ARCOM => sub { my($env, $target, @sources) = @_; - # code to create an archive - } - ); - -A build action may be associated directly with one or more target files -via the C<Command> method; see below. - -=head2 Construction commands - -A construction command goes through expansion of construction variables -and C<%-> pseudo-variables, as described above, to create the actual -command line that Cons will execute to generate the target file or -files. - -After substitution occurs, strings of white space are converted into -single blanks, and leading and trailing white space is eliminated. It -is therefore currently not possible to introduce variable length white -space in strings passed into a command. - -If a multi-line command string is provided, the commands are executed -sequentially. If any of the commands fails, then none of the rest are -executed, and the target is not marked as updated, i.e. a new signature is -not stored for the target. - -Normally, if all the commands succeed, and return a zero status (or whatever -platform-specific indication of success is required), then a new signature -is stored for the target. If a command erroneously reports success even -after a failure, then Cons will assume that the target file created by that -command is accurate and up-to-date. - -The first word of each command string, after expansion, is assumed to be an -executable command looked up on the C<PATH> environment variable (which is, -in turn, specified by the C<ENV> construction variable). If this command is -found on the path, then the target will depend upon it: the command will -therefore be automatically built, as necessary. It's possible to write -multi-part commands to some shells, separated by semi-colons. Only the first -command word will be depended upon, however, so if you write your command -strings this way, you must either explicitly set up a dependency (with the -C<Depends> method), or be sure that the command you are using is a system -command which is expected to be available. If it isn't available, you will, -of course, get an error. - -Cons normally prints a command before executing it. This behavior is -suppressed if the first character of the command is C<@>. Note that -you may need to separate the C<@> from the command name or escape it to -prevent C<@cmd> from looking like an array to Perl quote operators that -perform interpolation: - - # The first command line is incorrect, - # because "@cp" looks like an array - # to the Perl qq// function. - # Use the second form instead. - Command $env 'foo', 'foo.in', qq( - @cp %< tempfile - @ cp tempfile %> - ); - -If there are shell meta characters anywhere in the expanded command line, -such as C<E<lt>>, C<E<gt>>, quotes, or semi-colon, then the command -will actually be executed by invoking a shell. This means that a command -such as: - - cd foo - -alone will typically fail, since there is no command C<cd> on the path. But -the command string: - - cd $<:d; tar cf $>:f $<:f - -when expanded will still contain the shell meta character semi-colon, and a -shell will be invoked to interpret the command. Since C<cd> is interpreted -by this sub-shell, the command will execute as expected. - -=head2 Perl expressions - -If any command (even one within a multi-line command) begins with -C<[perl]>, the remainder of that command line will be evaluated by the -running Perl instead of being forked by the shell. If an error occurs -in parsing the Perl code, or if the Perl expression returns 0 or undef, -the command will be considered to have failed. For example, here is a -simple command which creates a file C<foo> directly from Perl: - - $env = new cons(); - Command $env 'foo', - qq([perl] open(FOO,'>foo');print FOO "hi\\n"; close(FOO); 1); - -Note that when the command is executed, you are in the same package as -when the F<Construct> or F<Conscript> file was read, so you can call -Perl functions you've defined in the same F<Construct> or F<Conscript> -file in which the C<Command> appears: - - $env = new cons(); - sub create_file { - my $file = shift; - open(FILE, ">$file"); - print FILE "hi\n"; - close(FILE); - return 1; - } - Command $env 'foo', "[perl] &create_file('%>')"; - -The Perl string will be used to generate the signature for the derived -file, so if you change the string, the file will be rebuilt. The contents -of any subroutines you call, however, are not part of the signature, -so if you modify a called subroutine such as C<create_file> above, -the target will I<not> be rebuilt. Caveat user. - -=head2 Perl code references [EXPERIMENTAL] - -Cons supports the ability to create a derived file by directly executing -a Perl code reference. This feature is considered EXPERIMENTAL and -subject to change in the future. - -A code reference may either be a named subroutine referenced by the -usual C<\&> syntax: - - sub build_output { - my($env, $target, @sources) = @_; - print "build_output building $target\n"; - open(OUT, ">$target"); - foreach $src (@sources) { - if (! open(IN, "<$src")) { - print STDERR "cannot open '$src': $!\n"; - return undef; - } - print OUT, <IN>; - } - close(OUT); - return 1; - } - Command $env 'output', \&build_output; - -or the code reference may be an anonymous subroutine: - - Command $env 'output', sub { - my($env, $target, @sources) = @_; - print "building $target\n"; - open(FILE, ">$target"); - print FILE "hello\n"; - close(FILE); - return 1; - }; - -To build the target file, the referenced subroutine is passed, in order: -the construction environment used to generate the target; the path -name of the target itself; and the path names of all the source files -necessary to build the target file. - -The code reference is expected to generate the target file, of course, -but may manipulate the source and target files in any way it chooses. -The code reference must return a false value (C<undef> or C<0>) if -the build of the file failed. Any true value indicates a successful -build of the target. - -Building target files using code references is considered EXPERIMENTAL -due to the following current limitations: - -=over 4 - -Cons does I<not> print anything to indicate the code reference is being -called to build the file. The only way to give the user any indication -is to have the code reference explicitly print some sort of "building" -message, as in the above examples. - -Cons does not generate any signatures for code references, so if the -code in the reference changes, the target will I<not> be rebuilt. - -Cons has no public method to allow a code reference to extract -construction variables. This would be good to allow generalization of -code references based on the current construction environment, but would -also complicate the problem of generating meaningful signatures for code -references. - -=back - -Support for building targets via code references has been released in -this version to encourage experimentation and the seeking of possible -solutions to the above limitations. - ---> - - <para> - - &SCons; supports several types of &build_actions; - that can be performed to build one or more target files. - Usually, a &build_action; is a command-line string - that invokes an external command. - A build action can also be an external command - specified as a list of arguments, - or even a Python function. - - </para> - - <para> - - Build action objects are created by the &Action; function. - This function is, in fact, what &SCons; uses - to interpret the &action; - keyword argument when you call the &Builder; function. - So the following line that creates a simple Builder: - - </para> - - <sconstruct> - b = Builder(action = 'build < $SOURCE > $TARGET') - </sconstruct> - - <para> - - Is equivalent to: - - </para> - - <sconstruct> - b = Builder(action = Action('build < $SOURCE > $TARGET')) - </sconstruct> - - <para> - - The advantage of using the &Action; function directly - is that it can take a number of additional options - to modify the action's behavior in many useful ways. - - </para> - - <section> - <title>Command Strings as Actions</title> - - <section> - <title>Suppressing Command-Line Printing</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Ignoring Exit Status</title> - - <para> - - XXX - - </para> - - </section> - - </section> - - <section> - <title>Argument Lists as Actions</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Python Functions as Actions</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Modifying How an Action is Printed</title> - - <section> - <title>XXX: the &strfunction; keyword argument</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>XXX: the &cmdstr; keyword argument</title> - - <para> - - XXX - - </para> - - </section> - - </section> - - <section> - <title>Making an Action Depend on Variable Contents: the &varlist; keyword argument</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>chdir=1</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Batch Building of Multiple Targets from Separate Sources: the &batch_key; keyword argument</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Manipulating the Exit Status of an Action: the &exitstatfunc; keyword argument</title> - - <para> - - XXX - - </para> - - </section> - - <!-- - - ???

The -command invoked is simply C<%CCCOM>, which expands, through substitution, -to the appropriate external command required to build each object.

Methods are provided for copying existing environments for this -purpose). Some internal variables, such as C<_IFLAGS> are created on demand, -but once set, they remain fixed for the life of the environment. - -The C<CFLAGS>, C<LDFLAGS>, and C<ARFLAGS> variables all supply a place -for passing options to the compiler, loader, and archiver, respectively. - -The C<INCDIRPREFIX> and C<INCDIRSUFFIX> variables specify option -strings to be appended to the beginning and end, respectively, of each -include directory so that the compiler knows where to find F<.h> files. -Similarly, the C<LIBDIRPREFIX> and C<LIBDIRSUFFIX> variables specify the -option string to be appended to the beginning of and end, respectively, -of each directory that the linker should search for libraries. - -Another variable, C<ENV>, is used to determine the system environment during -the execution of an external command. By default, the only environment -variable that is set is C<PATH>, which is the execution path for a UNIX -command. For the utmost reproducibility, you should really arrange to set -your own execution path, in your top-level F<Construct> file (or perhaps by -importing an appropriate construction package with the Perl C<use> -command). The default variables are intended to get you off the ground. - -=head2 Expanding variables in construction commands - -Within a construction command, construction variables will be expanded -according to the rules described above. In addition to normal variable -expansion from the construction environment, construction commands also -expand the following pseudo-variables to insert the specific input and -output files in the command line that will be executed: - -=over 10 - -=item %> - -The target file name. In a multi-target command, this expands to the -first target mentioned.) - -=item %0 - -Same as C<%E<gt>>. - -=item %1, %2, ..., %9 - -These refer to the first through ninth input file, respectively. - -=item %E<lt> - -The full set of input file names. If any of these have been used -anywhere else in the current command line (via C<%1>, C<%2>, etc.), then -those will be deleted from the list provided by C<%E<lt>>. Consider the -following command found in a F<Conscript> file in the F<test> directory: - - Command $env 'tgt', qw(foo bar baz), qq( - echo %< -i %1 > %> - echo %< -i %2 >> %> - echo %< -i %3 >> %> - ); - -If F<tgt> needed to be updated, then this would result in the execution of -the following commands, assuming that no remapping has been established for -the F<test> directory: - - echo test/bar test/baz -i test/foo > test/tgt - echo test/foo test/baz -i test/bar >> test/tgt - echo test/foo test/bar -i test/baz >> test/tgt - -=back - -Any of the above pseudo-variables may be followed immediately by one of -the following suffixes to select a portion of the expanded path name: - - :a the absolute path to the file name - :b the directory plus the file name stripped of any suffix - :d the directory - :f the file name - :s the file name suffix - :F the file name stripped of any suffix - :S the absolute path path to a Linked source file - -Continuing with the above example, C<%E<lt>:f> would expand to C<foo bar baz>, -and C<%E<gt>:d> would expand to C<test>. - -There are additional C<%> elements which affect the command line(s): - -=over 10 - -=item %[ %] - -It is possible to programmatically rewrite part of the command by -enclosing part of it between C<%[> and C<%]>. This will call the -construction variable named as the first word enclosed in the brackets -as a Perl code reference; the results of this call will be used to -replace the contents of the brackets in the command line. For example, -given an existing input file named F<tgt.in>: - - @keywords = qw(foo bar baz); - $env = new cons(X_COMMA => sub { join(",", @_) }); - Command $env 'tgt', 'tgt.in', qq( - echo '# Keywords: %[X_COMMA @keywords %]' > %> - cat %< >> %> - ); - -This will execute: - - echo '# Keywords: foo,bar,baz' > tgt - cat tgt.in >> tgt - -=item %( %) - -Cons includes the text of the command line in the MD5 signature for a -build, so that targets get rebuilt if you change the command line (to -add or remove an option, for example). Command-line text in between -C<%(> and C<%)>, however, will be ignored for MD5 signature calculation. - -Internally, Cons uses C<%(> and C<%)> around include and library -directory options (C<-I> and C<-L> on UNIX systems, C</I> and -C</LIBPATH> on Windows NT) to avoid rebuilds just because the directory -list changes. Rebuilds occur only if the changed directory list causes -any included I<files> to change, and a changed include file is detected -by the MD5 signature calculation on the actual file contents. - -=back - -XXX DESCRIBE THE Literal() FUNCTION, TOO XXX - -=head2 Expanding construction variables in file names - -Cons expands construction variables in the source and target file names -passed to the various construction methods according to the expansion -rules described above: - - $env = new cons( - DESTDIR => 'programs', - SRCDIR => 'src', - );

See discussion of the C<Link> command, below, for details.) - - -=head2 Using modules in build scripts - -You may pull modules into each F<Conscript> file using the normal Perl -C<use> or C<require> statements: - - use English; - require My::Module; - -Each C<use> or C<require> only affects the one F<Conscript> file in which -it appears.

To import a variable, it must have been B<exported> by the parent -and initialized (otherwise an error will occur). - - -=head2 The Export command - -The C<Export> command is used as in the following example: - - $env = new cons(); - $INCLUDE = "#export/include"; - $LIB = "#export/lib"; - Export qw( env INCLUDE LIB ); - Build qw( util/Conscript ); - -The values of the simple variables mentioned in the C<Export> list will be -squirreled away by any subsequent C<Build> commands.

Other variables, objects, etc. can be exported by -reference, but all scripts will refer to the same object, and this object -should be considered to be read-only by the subsidiary scripts and by the -original exporting script. It's acceptable, however, to assign a new value -to the exported scalar variable, that won't change the underlying variable -referenced. This sequence, for example, is OK: - - $env = new cons(); - Export qw( env INCLUDE LIB ); - Build qw( util/Conscript ); - $env = new cons(CFLAGS => '-O'); - Build qw( other/Conscript ); - -It doesn't matter whether the variable is set before or after the C<Export> -command. The important thing is the value of the variable at the time the -C<Build> command is executed. This is what gets squirreled away. Any -subsequent C<Export> commands, by the way, invalidate the first: you must -mention all the variables you wish to export on each C<Export> command. - - -=head2 The Import command - -Variables exported by the C<Export> command can be imported into subsidiary -scripts by the C<Import> command. The subsidiary script always imports -variables directly from the superior script. Consider this example: - - Import qw( env INCLUDE ); - -This is only legal if the parent script exported both C<$env> and -C<$INCLUDE>. It also must have given each of these variables values. It is -OK for the subsidiary script to only import a subset of the exported -variables (in this example, C<$LIB>, which was exported by the previous -example, is not imported). - -All the imported variables are automatically re-exported, so the sequence: - - Import qw ( env INCLUDE ); - Build qw ( beneath-me/Conscript ); - -will supply both C<$env> and C<$INCLUDE> to the subsidiary file. If only -C<$env> is to be exported, then the following will suffice: - - Import qw ( env INCLUDE ); - Export qw ( env ); - Build qw ( beneath-me/Conscript ); - -Needless to say, the variables may be modified locally before invoking -C<Build> on the subsidiary script. - -=head2 Build script evaluation order - -The only constraint on the ordering of build scripts is that superior -scripts are evaluated before their inferior scripts. The top-level -F<Construct> file, for instance, is evaluated first, followed by any -inferior scripts. This is all you really need to know about the evaluation -order, since order is generally irrelevant.

Why not Make? - -Cons is a B<make> replacement. In the following paragraphs, we look at a few -of the undesirable characteristics of make, and typical build environments -based on make, that motivated the development of Cons. - -=head2 Build complexity - -Traditional make-based systems of any size tend to become quite complex. The -original make utility and its derivatives have contributed to this tendency -in a number of ways. Make is not good at dealing with systems that are -spread over multiple directories. Various work-arounds are used to overcome -this difficulty; the usual choice is for make to invoke itself recursively -for each sub-directory of a build. This leads to complicated code, in which -it is often unclear how a variable is set, or what effect the setting of a -variable will have on the build as a whole. The make scripting language has -gradually been extended to provide more possibilities, but these have -largely served to clutter an already overextended language. Often, builds -are done in multiple passes in order to provide appropriate products from -one directory to another directory. This represents a further increase in -build complexity. - - -=head2 Build reproducibility - -The bane of all makes has always been the correct handling of -dependencies. Most often, an attempt is made to do a reasonable job of -dependencies within a single directory, but no serious attempt is made to do -the job between directories. Even when dependencies are working correctly, -make's reliance on a simple time stamp comparison to determine whether a -file is out of date with respect to its dependents is not, in general, -adequate for determining when a file should be rederived. If an external -library, for example, is rebuilt and then ``snapped'' into place, the -timestamps on its newly created files may well be earlier than the last -local build, since it was built before it became visible. - - -=head2 Variant builds - -Make provides only limited facilities for handling variant builds. With the -proliferation of hardware platforms and the need for debuggable -vs. optimized code, the ability to easily create these variants is -essential. More importantly, if variants are created, it is important to -either be able to separate the variants or to be able to reproduce the -original or variant at will. With make it is very difficult to separate the -builds into multiple build directories, separate from the source. And if -this technique isn't used, it's also virtually impossible to guarantee at -any given time which variant is present in the tree, without resorting to a -complete rebuild. - - -=head2 Repositories - -Make provides only limited support for building software from code that -exists in a central repository directory structure. The VPATH feature of -GNU make (and some other make implementations) is intended to provide this, -but doesn't work as expected: it changes the path of target file to the -VPATH name too early in its analysis, and therefore searches for all -dependencies in the VPATH directory. To ensure correct development builds, -it is important to be able to create a file in a local build directory and -have any files in a code repository (a VPATH directory, in make terms) that -depend on the local file get rebuilt properly. This isn't possible with -VPATH, without coding a lot of complex repository knowledge directly into -the makefiles. - ---> - - <para> - - XXX - - </para> - - <section> - <title>Differences Between &Make; and &SCons;</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Advantages of &SCons; Over &Make;</title> - - <para> - - XXX - - </para> - - </section> diff --git a/doc/user/make.xml b/doc/user/make.xml index 876168a..69dd7f4 100644 --- a/doc/user/make.xml +++ b/doc/user/make.xml @@ -1,6 +1,27 @@ +<?xml version='1.0'?> +<!DOCTYPE sconsdoc [ + <!ENTITY % scons SYSTEM "../scons.mod"> + %scons; + + <!ENTITY % builders-mod SYSTEM "../generated/builders.mod"> + %builders-mod; + <!ENTITY % functions-mod SYSTEM "../generated/functions.mod"> + %functions-mod; + <!ENTITY % tools-mod SYSTEM "../generated/tools.mod"> + %tools-mod; + <!ENTITY % variables-mod SYSTEM "../generated/variables.mod"> + %variables-mod; +]> + +<appendix id="app-make" + xmlns="http://www.scons.org/dbxsd/v1.0" + xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" + xsi:schemaLocation="http://www.scons.org/dbxsd/v1.0/scons.xsd scons.xsd"> +<title>Converting From Make</title> + <!-- - Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 The SCons Foundation + Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 The SCons Foundation Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the @@ -119,3 +140,5 @@ the makefiles. </para> </section> + +</appendix> diff --git a/doc/user/mergeflags.in b/doc/user/mergeflags.in deleted file mode 100644 index f1997a0..0000000 --- a/doc/user/mergeflags.in +++ /dev/null @@ -1,137 +0,0 @@ -<!-- - - Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 The SCons Foundation - - Permission is hereby granted, free of charge, to any person obtaining - a copy of this software and associated documentation files (the - "Software"), to deal in the Software without restriction, including - without limitation the rights to use, copy, modify, merge, publish, - distribute, sublicense, and/or sell copies of the Software, and to - permit persons to whom the Software is furnished to do so, subject to - the following conditions: - - The above copyright notice and this permission notice shall be included - in all copies or substantial portions of the Software. - - THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY - KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE - WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND - NONINFRINGEMENT.

function does <emphasis>not</emphasis> - perform general variable substitution - (because there's not necessarily a construction - environment involved in evaluating a node - like a source file, for example). - - </para> - - <para> - - You can also specify a list of strings - to the &Progress;

- only print a new "spinner" string - once every five evaluated nodes. - Using an <literal>interval=</literal> count, - even with strings that use <literal>$TARGET</literal> like - our examples above, - can be a good way to lessen the - work that &SCons;

evaluate its - dependency graph twice, - first to count the total and - the second time to actually build the targets. - This would be necessary because - you can't know in advance which - target(s) the user actually requested - to be built. - The entire build may consist of thousands of Nodes, - for example, - but maybe the user specifically requested - that only a single object file be built.) - - </para> - - </section> - - <section> - <title>Printing Detailed Build Status: the &GetBuildFailures;

If you want to know what script -installs F<export/include/foo.h>, for example, just type: - - % cons -pw export/include/foo.h - -=head1 Selective builds - -Cons provides two methods for reducing the size of given build. The first is -by specifying targets on the command line, and the second is a method for -pruning the build tree. We'll consider target specification first. - - -=head2 Selective targeting - -Like make, Cons allows the specification of ``targets'' on the command -line. Cons targets may be either files or directories. When a directory is -specified, this is simply a short-hand notation for every derivable -product-,-that Cons knows about-,-in the specified directory and below. For -example: - - % cons build/hello/hello.o - -means build F<hello.o> and everything that F<hello.o> might need. This is -from a previous version of the B<Hello, World!> program in which F<hello.o> -depended upon F<export/include/world.h>. If that file is not up-to-date -(because someone modified F<src/world/world.h)>, then it will be rebuilt, -even though it is in a directory remote from F<build/hello>. - -In this example: - - % cons build - -Everything in the F<build> directory is built, if necessary. Again, this may -cause more files to be built. In particular, both F<export/include/world.h> -and F<export/lib/libworld.a> are required by the F<build/hello> directory, -and so they will be built if they are out-of-date. - -If we do, instead: - - % cons export - -then only the files that should be installed in the export directory will be -rebuilt, if necessary, and then installed there. Note that C<cons build> -might build files that C<cons export> doesn't build, and vice-versa. - - -=head1 Build Pruning - -In conjunction with target selection, B<build pruning> can be used to reduce -the scope of the build. In the previous peAcH and baNaNa example, we have -already seen how script-driven build pruning can be used to make only half -of the potential build available for any given invocation of C<cons>. Cons -also provides, as a convenience, a command line convention that allows you -to specify which F<Conscript> files actually get ``built''-,-that is, -incorporated into the build tree. For example: - - % cons build +world - -The C<+> argument introduces a Perl regular expression. This must, of -course, be quoted at the shell level if there are any shell meta-characters -within the expression. The expression is matched against each F<Conscript> -file which has been mentioned in a C<Build> statement, and only those -scripts with matching names are actually incorporated into the build -tree. Multiple such arguments are allowed, in which case a match against any -of them is sufficient to cause a script to be included. - -In the example, above, the F<hello> program will not be built, since Cons -will have no knowledge of the script F<hello/Conscript>. The F<libworld.a> -archive will be built, however, if need be. - -There are a couple of uses for build pruning via the command line. Perhaps -the most useful is the ability to make local changes, and then, with -sufficient knowledge of the consequences of those changes, restrict the size -of the build tree in order to speed up the rebuild time. A second use for -build pruning is to actively prevent the recompilation of certain files that -you know will recompile due to, for example, a modified header file. You may -know that either the changes to the header file are immaterial, or that the -changes may be safely ignored for most of the tree, for testing -purposes.With Cons, the view is that it is pragmatic to admit this type of -behavior, with the understanding that on the next full build everything that -needs to be rebuilt will be. There is no equivalent to a ``make touch'' -command, to mark files as permanently up-to-date. So any risk that is -incurred by build pruning is mitigated. For release quality work, obviously, -we recommend that you do not use build pruning (it's perfectly OK to use -during integration, however, for checking compilation, etc. Just be sure to -do an unconstrained build before committing the integration). - ---> - - <para> - - XXX - - </para> - - <section> - <title>Command-Line Options</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Getting at Command-Line Arguments</title> - - <para> - - XXX - - </para> - - </section> - - <section> - <title>Selective Builds</title> - - <para> - - XXX - - </para> - - </section> - - <!-- - - <section> - <title>Build Pruning</title> - - <para> - - XXX - - </para> - - </section> - - --> - - <section> - <title>Overriding Construction Variables</title> - - <para> - - XXX - - </para> - - </section> diff --git a/doc/user/run.xml b/doc/user/run.xml index 8a5075b..464a5a8 100644 --- a/doc/user/run.xml +++ b/doc/user/run.xml @@ -1,6 +1,27 @@ +<?xml version='1.0'?> +<!DOCTYPE sconsdoc [ + <!ENTITY % scons SYSTEM "../scons.mod"> + %scons; + + <!ENTITY % builders-mod SYSTEM "../generated/builders.mod"> + %builders-mod; + <!ENTITY % functions-mod SYSTEM "../generated/functions.mod"> + %functions-mod; + <!ENTITY % tools-mod SYSTEM "../generated/tools.mod"> + %tools-mod; + <!ENTITY % variables-mod SYSTEM "../generated/variables.mod"> + %variables-mod; +]> + +<chapter id="chap-run" + xmlns="http://www.scons.org/dbxsd/v1.0" + xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" + xsi:schemaLocation="http://www.scons.org/dbxsd/v1.0/scons.xsd scons.xsd"> +<title>How to Run &SCons;</title> + <!-- - Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 The SCons Foundation + Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014 The SCons Foundation Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the @@ -373,3 +394,5 @@ do an unconstrained build before committing the integration). </para> </section> + +</chapter> diff --git a/doc/user/scanners.in b/doc/user/scanners.in deleted file mode 100644 index 9237fb3..0000000 --- a/doc/user/scanners.in +++ /dev/null @@ -1,392 +0,0 @@ -<!-- - - Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013 The SCons Foundation - - Permission is hereby granted, free of charge, to any person obtaining - a copy of this software and associated documentation files (the - "Software"), to deal in the Software without restriction, including - without limitation the rights to use, copy, modify, merge, publish, - distribute, sublicense, and/or sell copies of the Software, and to - permit persons to whom the Software is furnished to do so, subject to - the following conditions: - - The above copyright notice and this permission notice shall be included - in all copies or substantial portions of the Software. - - THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY - KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE - WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND - NONINFRINGEMENT.

This is not very general, but seems good -enough, especially if you have the luxury of writing your own utilities -and can control the use of the search path in a standard way. - -Here's a real example, taken from a F<Construct> file here: - - sub cons::SMFgen { - my($env, @tables) = @_; - foreach $t (@tables) { - $env->QuickScan(sub { /\b\S*?\.smf\b/g }, "$t.smf", - $env->{SMF_INCLUDE_PATH}); - $env->Command(["$t.smdb.cc","$t.smdb.h","$t.snmp.cc", - "$t.ami.cc", "$t.http.cc"], "$t.smf", - q(smfgen %( %SMF_INCLUDE_OPT %) %<)); - } - } - -The subroutine above finds all names of the form <name>.smf in the -file. It will return the names even if they're found within comments, -but that's OK (the mechanism is forgiving of extra files; they're just -ignored on the assumption that the missing file will be noticed when -the program, in this example, smfgen, is actually invoked). - -[NOTE that the form C<$env-E<gt>QuickScan ...> and C<$env-E<gt>Command -...> should not be necessary, but, for some reason, is required -for this particular invocation. This appears to be a bug in Perl or -a misunderstanding on my part; this invocation style does not always -appear to be necessary.] - -Here is another way to build the same scanner. This one uses an -explicit code reference, and also (unnecessarily, in this case) reads -the whole file itself: - - sub myscan { - my(@includes); - do { - push(@includes, /\b\S*?\.smf\b/g); - } while <SCAN>; - @includes - } - -Note that the order of the loop is reversed, with the loop test at the -end. This is because the first line is already read for you. This scanner -can be attached to a source file by: - - QuickScan $env \&myscan, "$_.smf"; - -This final example, which scans a different type of input file, takes -over the file scanning rather than being called for each input line: - - $env->QuickScan( - sub { my(@includes) = (); - do { - push(@includes, $3) - if /^(#include|import)\s+(\")(.+)(\")/ && $3 - } while <SCAN>; - @includes - }, - "$idlFileName", - "$env->{CPPPATH};$BUILD/ActiveContext/ACSCLientInterfaces" - ); - ---> - - <para> - - &SCons; has built-in scanners that know how to look in - C, Fortran and IDL source files for information about - other files that targets built from those files depend on--for example, - in the case of files that use the C preprocessor, - the <filename>.h</filename> files that are specified - using <literal>#include</literal> lines in the source. - You can use the same mechanisms that &SCons; uses to create - its built-in scanners to write scanners of your own for file types - that &SCons; does not know how to scan "out of the box." - - </para> - - <section> - <title>A Simple Scanner Example</title> - - <para> - - Suppose, for example, that we want to create a simple scanner - for <filename>.foo</filename> files. - A <filename>.foo</filename> file contains some text that - will be processed, - and can include other files on lines that begin - with <literal>include</literal> - followed by a file name: - - </para> - - <programlisting> - include filename.foo - </programlisting> - - <para> - - Scanning a file will be handled by a Python function - that you must supply. - Here is a function that will use the Python - <filename>re</filename> module - to scan for the <literal>include</literal> lines in our example: - - </para> - - <programlisting> - import re - - include_re = re.compile(r'^include\s+(\S+)$', re.M) - - def kfile_scan(node, env, path, arg): - contents = node.get_text_contents() - return env.File(include_re.findall(contents)) - </programlisting> - - <para> - - It is important to note that you - have to return a list of File nodes from the scanner function, simple - strings for the file names won't do.

This makes it much easier to keep track of -just what is a source file, and also makes it simpler to handle B<variant> -builds, especially if you want the variant builds to co-exist. - -=head2 Separating build and source directories using the Link command - -Cons provides a simple mechanism that handles all of these requirements. The -C<Link> command is invoked as in this example: - - Link 'build' => 'src'; - -The specified directories are ``linked'' to the specified source -directory. Let's suppose that you setup a source directory, F<src>, with the -sub-directories F<world> and F<hello> below it, as in the previous -example. You could then substitute for the original build lines the -following: - - Build qw( - build/world/Conscript - build/hello/Conscript - ); - -Notice that you treat the F<Conscript> file as if it existed in the build -directory. Now if you type the same command as before, you will get the -following results: - - % cons export - Install build/world/world.h as export/include/world.h - cc -Iexport/include -c build/hello/hello.c -o build/hello/hello.o - cc -Iexport/include -c build/world/world.c -o build/world/world.o - ar r build/world/libworld.a build/world/world.o - ar: creating build/world/libworld.a - ranlib build/world/libworld.a - Install build/world/libworld.a as export/lib/libworld.a - cc -o build/hello/hello build/hello/hello.o -Lexport/lib -lworld - Install build/hello/hello as export/bin/hello - -Again, Cons has taken care of the details for you. In particular, you will -notice that all the builds are done using source files and object files from -the build directory. For example, F<build/world/world.o> is compiled from -F<build/world/world.c>, and F<export/include/world.h> is installed from -F<build/world/world.h>. This is accomplished on most systems by the simple -expedient of ``hard'' linking the required files from each source directory -into the appropriate build directory. - -The links are maintained correctly by Cons, no matter what you do to the -source directory. If you modify a source file, your editor may do this ``in -place'' or it may rename it first and create a new file. In the latter case, -any hard link will be lost.

(exclamation point). For example, -if we add a ``!'' to the beginning of a source file: - - Program $env "foo", "!foo.c"; # Notice initial ! on foo.c - -Cons will compile the target as follows: - - cc -c src/foo.c -o build/foo.o - cc -o build/foo build/foo.o - -Notice that Cons has compiled the program from the the F<src/foo.c> -source file.
