NAME
cook - a file construction tool
DESCRIPTION
The cook program is a tool for constructing files, and maintaining
referential integrity between files. It is given a set of files to
create, and recipes of how to create and maintain them. In any non-
trivial program there will be prerequisites to performing the actions
necessary to creating any file, such as include files. The cook
program provides a mechanism to define these.
When a program is being developed or maintained, the programmer will
typically change one file of several which comprise the program. The
cook program examines the last-modified times of the files to see when
the prerequisites of a file have changed, implying that the file needs
to be recreated as it is logically out of date.
The cook program also provides a facility for implicit recipes,
allowing users to specify how to form a file with a given suffix from a
file with a different suffix. For example, to create filename.o from
filename.c

NEW IN THIS RELEASE
A number of features have been added to cook with this release. The
following list is only a summary; for excruciating detail, and also
acknowlegements of those who generously sent me feedback, please see
the etc/CHANGES.* files included in this distribution.
Version 2.27 (2007-Mar-13)
* An ANSI C compiler is now required to build Cook.
* A bug has been fixed in the cook_bom command's -prefix and -suffix
options.
* The fingerprint code is now more robust when faced with file
modification time trickery by users.
* A few things have been improved for using Cook on Cygwin.
* The c_incl -r option now understands .PSPIC directives, as well as
.so directives.
Version 2.26 (2006-Jan-17)
* A number of build problems have been fixed.
* A bug has been fixed in the tell-position flag. It wasn't actually
giving the file name and line number when executing commands if you
used the "set tell-position" variants, only the -tell-position command
line option.
* The email address in the LSM file has been fixed,
* A bug has been fixed in the cook -fp-update command, it would
segfault in some cases.
* A bug has been fixed in the cookbook include file processing.
* A bug has been fixed in the negative flag setting (comamnd line
options and "set" clauses).
* The find_command command now copes better with directories it is not
allowed to access.
* A Java cookbook has been added to to the distribution.
* A bug has been fixed in the execution of some commands. If any words
of the command had spaces in them, it did not pass it to a shell to be
executed, but instead constructed a command of a different shape than
the user expected.
Version 2.25 (2004-Jun-10)
* The ./configure script now understands the --with-nlsdir option, used
to specify the install location of the .mo files.
* A bug has been fixed on Linux (and it only ever ocurred on Linux)
where cook would suddenly stop for no reason with exit status 1. Turns
out that sometimes fflush(stderr) returns an EAGAIN error.
* A bug has been fixed which caused the cook -script option to produce
invalid shell scripts when a recipe body contained no statements.
* A bug has been fixed in the graph file pair generation, used to
generate warnings about dangerous #include-cooked contents.
* The metering output now includes elapsed times and percentages.
* There is a new tell-position setting, so that when Cook prints a
command it is about to run, it includes the file name and line nunmber
of the command. This can be useful when debugging cookbooks.
* A bug has been fixed in the output line wrapping. Once again it
adapts to the window width.
Version 2.24 (2003-Jul-17)
* A major problem with parallel execution and hangs has been fixed.
The table indexed by process ID was now growing correctly.
* Some words have been added to the User Guide about the SHELL
environment variable, and the effects of errors in the .profile file.
* Building RPMs has been improved, and the spec file now uses more
modern RPM features.
* Building on Cygwin has been improved.
* Building on AIX has been improved.
Version 2.23 (2003-May-01)
* Build problem encountered using newer bersions of GNU Bison mave been
fixed.
* For Cook developers, there is now a .ae file on the web site.
* An error in the documentation of the errok flag has been fixed.
Version 2.22 (2003-Feb-28)
* A small problem with fingerprints has been fixed.
* A tutorial has been contributed.
* You can now have international characters in comments.
* A C++ cookbook has been added.
* A test failure on Cygwin has been fixed.
* The [read] and [read_lines] builtin functions have been added. See
the Reference Manual for more information.
Version 2.21 (2002-Aug-26)
* The c_incl(1) command now accepts the -stripdot and -nostripdot
options. These may be used to control the removal of redundant leading
dot directories.
* A bug has been fixed where cascade recipes failed to heed the
stripdot setting.
* There is a new [stripdot] function, so that you can strip leading dot
directories from file names within functions.
* A bug has been fixed in how the builtin functions which manipulate
build graphs were called. This fixed a problem with freeing a string
which had already been freed.
Version 2.20 (2002-Jun-06)
* There is a fix for the build problems caused by recent GNU Gettext
releases.
* The fingerprint handling is now more robust, particularly when faced
with files that move backwards in time.
* There is a fix for the build problems caused by recent Bison
releases.
Version 2.19 (2002-Feb-19)
* Some introduced with recent versions of GNU Bison have been fixed.
Bison's include file insulation didn't use YY in the insulating symbol
(just to be completely inconsistent) and in another case a namespace
clash occurred for a function name.
* The generated Makefile has been improved, along with other small
build and install improvements.
* A top-level fail statement how halts the parse as soon as it is
executed. This will make it more useful for checking build
environments.
* Documentation about cook_rsh(1) has been added to the Parallel
chapter of the User Guide.
Version 2.18 (2001-Oct-15)
* A bug has been fixed in the ingredients-fingerprint recipe attribute.
It was failing to save the fingerprint cache file in some cases, and
thus came to incorrect conclusions on following runs.
* The (exists) ingredients attribute has been fixed so that it no
longer implies behavious rimilar to set shallow.
* There is a new cook_rsh(1) program, for use with the host-binding
recipe attribute, which allows you to load balance builds across
classes of hosts. See cook_rsh(1) and the Parallel chapter of the User
Guide for more information.
* Some build problems have been fixed on various platforms.
* More keywords are now understood for M4 include directives.
Version 2.17 (2001-Apr-25)
* When using file fingerprints, the way the .cook.fp file is written
has been changed, so that the timestamp of the containing directory is
modified much less often. This is useul in combination with the
cook_bom(1) utility.
* A bug has been fixed under Cygwin, where archive members were not
being fingerprinted correctly.
* A bug has been fixed in the [quote] function. It now quotes all
sh(1), csh(1) and bash(1) special characters correctly.
* A bug has been fixed in the [uptodate] function. It now works as
advertised.
* There is a new ingredients-fingerprint recipe flag. This means that
you can now cause a recipe to re-trigger when the ingredients list
changes. This is especially useful when a library has a file removed.
* The dependency graph can now have the edge types specified. The
``weak'' edge type if useful for managing links, and the ``exists''
edge type is useful for managing version stamps. See the User Guide
for more information.
Version 2.16 (2000-Oct-25)
* The stringset function now accepts a `+' operator. While union is
implicit, the apparrently redundant `+' operator is useful for
cancelling the other operators.
* The ``reason and fingerprint bug'' has been fixed. This caused a
mysterious error message to appear sometimes when using the -reson
option incombination with fingerprints.
* The % and %n patterns are now allowed to match the empty string,
provided they aren't the first thing in the pattern (otherwise
undesirable absolute path problems can occur).
* The c_incl(1) command now accepts `-' as a file name on the command
line, meaning standard input.
* Some improvements have been made to the Cygwin support, extending the
``.exe'' automatic executable suffix coverage to a couple more places.
* A bug in the ``c'' cookbook has been fixed, which was getting .h
dependency files wrong.
Version 2.15 (2000-Apr-11)
* The C_incl(1) problem with absolute paths has been fixed.
* A bug has been fixed which caused problems on Solaris and SGI, where
Cook would report a No child processes error.
Version 2.12 (2000-Mar-28)
* The c_incl program now has a -quote-filenames option, which means
that you can have filenames with spaces and special characters in them.
* A bug in the c_incl program's path flattening has been fixed.
* A small Y2K bug has been fixed in the date parsing used by the
cooktime(1) command.
* A bug which caused the -parallel option to lose track of processes
when you used [execute] in a recipe body has been fixed.
* The restrictions on the placement of the placement of %0 in a pattern
have been dropped; too many people didn't like it. This does not break
any cookbooks.
* Cook now copes with the absence of the HOME environment variable.
This was a problem for CGI scripts.
Version 2.11 (1999-Nov-04)
* Numerous portability problems have been fixed in the configure and
build.
* A bug has been fixed which prevented Cook from working correctly when
run by some versions of cron(8) and at(1).
* There is a new cook_bom --ignore option, allowing you to nominate
file patterns that you don't want in the file lists.
* There is a new [__FUNCTION__] variable, which contains the name of
the executing function, which suppliments the existing [__FILE__] and
[__LINE__] variables.
* Functions now have local variables, just put the word local on the
left-hand-side of the first assignment. Local variables are reentrant
and thread-safe.
Version 2.10 (1999-Sep-06)
* The [print] and [write] functions now work more sensably with the
-SCript option.
* The fingerprint code has been improved. It now does considerably
fewer redundant fingeprint calculations, resulting is some very welcome
speed improvements.
* The behaviour of the remote shell invocation to cope with rshd at the
remote end failing to spawn a shell, and it copes with the default
shell at the remote end not being the Bourne shell.
* The -PARallel behaviour has been improved, so that it now looks for
child process who have finished more than it looks for recipes to run.
This doesn't change the semantics any, but it matches user expectations
far better (and results in shorter-lived zombie processes).
* The set meter recipe flag works once more. (It stopped working when
the parallel modifications were made, and mysteriously forgotten until
now.)
* There are some changes made to the fingerprinting code to detect when
files under ClearCase move backwards in time (because the underlying
file version is ``uncovered'') meaning that the derived (object) files
need to be rebuilt.
* There is a new [mtime-seconds] function, similar to the [mtime]
function, except that it returns seconds since the epoch, rather than a
human readable date. More useful to handing to [expr].
* A bug has been fixed on SGI IRIX which failed to cope with not being
able to create directories because they already exist.
* Ingredient recipes (ones with no body) may now have a double colon
rather than a single colon, even when there is more than on target
specified. Some users may find this a more natural syntax for
ingredients recipes.
* The [expr] function now reports an error when given a number too big
to represent, rather than quietly returning wrong answers. The range
of representable values depends on your system.
* Cook now works with GNU Regex correctly on Windows-NT.
Version 2.9 (1999-May-27)
* There is a new ``for each'' style looping construct. See the User
Guide for more information.
* It is now possible to use regular expression patterns, instead of
Cook's native patterns. You can set this for a whole cookbook or
individual recipes. The default is to use Cook's native patterns. See
the File Name Patterns chapter of the User Guide for more information.
* A bug which caused host-binding and single-thread to core dump has
been fixed.
* All text file input now copes with CRLF sequences, so mixing NT and
Unix builds on the one file server no longer creates problems.
* Fingerprints are now cached per-directory, rather than one huge file
for an entire directory tree. This is more useful in recursive build
and [search_list] situations.
* The [cando], [cook] and [uptodate] functions now return lists of
successful files, rather than a simple true/false result.
* The [in] and [matches] functions now return the list index (1 based)
of the matching word. See the User Guide for more information.
* There is a new cook -web option, to print a HTML web page on the
standard output, representing the dependency graph. This is useful in
documenting the build process, or debugging cookbooks.
* There is a new cook --fingerprint-update option which scans the
directory tree below the current directory and updates the file
fingerprints. This helps when you use another tool (such as RCS or
ClearCase) which alters the file but preserves the file's modification
time.
* There is a new [write] function for writing text files. This is
useful for coping with Windows-NT's absurdly short command lines.
Version 2.8 (1999-Feb-01)
* The remote host-binding code has been improved to cope with
staggeringly long commands (which tended to make rsh(1) barf), and also
wierd and wonderfull $SHELL settings.
* The #include directive now accepts more than one file, to be more
symmetric with the #include-cooked directive.
* A bug has been fixed where cooktime gave an incorrect error message
if setting the file's utimes failed.
* The configure script has been improved for use on non-UNIX systems.
* There is a new builtin [cook] function, a natural companion for the
[cando] and [uptodate] functions. See the Cook User Guide for more
information.
Version 2.7 (1998-Dec-30)
* There is a new cook_bom(1) command (Bill Of Materials). This may be
used to efficiently scan a directory tree for files, so that
ingredients lists may be produced automatically. See cook_bom(1) for
more information.
* There is a new assign-append statement, so you can now use += to
append to the value of a variable. See the User Guide for more
information.
* There is a new gate-first recipe flag, which causes the recipe gate
to be evaluated before the ingredients are derived, rather than after.
* The c_incl(1) command has a new --interior-files option, so you can
tell it about include files that don't exist yet. This is helpful when
they are generated, i.e. they are interior files of the dependency
graph, hence the option name.
* There is a new [interior-files] function, which returns the files
interior to the dependency graph (constructed by a recipe), and a
complementatry [leaf-files] function, which returns the leaf files of
the dependency graph (not constructed by any recipe).
* There is a new ``no-include-cooked-warning'' flag, if you want to
suppress the warnings about derived file dependencies in include-cooked
files.
* There is a new relative_dirname built-in function, similar to the
existing dirname function, but it returns ``.'' for files with no
directory part, rather than the absolute path of the current directory.
Version 2.6 (1998-Nov-09)
* Cook has been ported to Windows-NT using CygWin32. See the BUILDING
file for details.
* There are two new functions (dos-path and un-dos-path) for use when
invoking non-CygWin32 WindowsNT programs. See the Cook User Guide for
more information.
* Fingerprints now work meaningfully with directories.
* A bug has been fixed in the pattern matching code. It would
sometimes cause core dumps.
* A bug involving fingerprints in combination with the search_list has
been fixed. Cook would occasionally conclude that a shallow target was
up-to-date when a shallow ingredient was edited to be the same as a
deeper ingredient.
* A bug has been fixed in cooktime. It would use an inappropriate
timezone offset on some systems.
Release 2.5 (1998-Sep-02)
* A problem which caused some tests to fail on Solaris' tmpfs now has a
work-around.
* The ``setenv'' statement has finally been documented. It's been in
the code tfor years, but I could never figure out why folks weren't
using it!
* A number of build problems on various systems have been fixed.
Release 2.4 (1998-Jul-21)
* There is a new form of dependencies. Known as cascaded dependencies,
they allow the user to associate additional dependencies with an
ingredient. For example, a C source file can be associated with
cascaded include dependencies. This means that all files which depend
on the C source file, also depend on the included files. The Cook
Reference Manual has been updated to include this new functionality.
* There is a new section of the Cook Reference Manual giving
suggestions and a template for building large projects.
* There is a new [expr] function, to calculate simple arithmetic
expressions. See the User Guide for more information.
* There is a new c_incl -no-recursion option, to prevent scanning
nested includes. This is of most use when combined with the new
cascade dependencies.
* There is a new [exists-symlink] function, which may be used to test
for the existence of symlinks. The [exists] function follows symbolic
links, and is not useful when manipulating the links themselves.
Release 2.3 (1998-May-20)
* There are 6 new special variables: graph_leaf_file,
graph_leaf_pattern, graph_interior_file, graph_interior_pattern,
graph_exterior_file and graph_exterior_pattern. These variables may be
used to define the leaves of the derivation graph (the accept forms),
and non-leave of the graph (the reject forms). This can make the graph
derivation faster, and greatly improves some error messages. This
functionality is of most use when you have an exact source file
manifest, e.g. from a software configuration management system. See
the User Guide for more information.
* The %0 pattern element has been extended to permit the matching of
absolute paths.
Release 2.2.2 (1997-Dec-10)
* There is a new statement type, allowing functions to be invoked as
subroutines in any place where a command may be invoked. See the User
Guide for more information.
* A number of problems with installing Cook have been fixed. This
includes changing -mgm to -mm for the documnetation formatting, and
missing include dependencies and missing rules for installing the man
pages.
* There is a new ``print'' builtin function. When combined with the
new function call statement, this provides a way of printing
information without invoking ``echo''. See the User Guide for more
information.
* Cook now defaults the language to ``en'' internally if neoither the
LANG nor LANGUAGE environment variable was set. This gives better
error messages.
Release 2.2.1 (1997-Nov-04)
* A bug was fixed where a recipe would fail to trigger if some, but not
all, of its targets were not present, but the existing targets were up-
to-date. This bug was introduced in the inference engine re-write.
Release 2.2 (1997-Oct-31)
* The c_incl utility has had two new languages added. It now
understands M4, and also has an ``optimistic'' language which can scan
many assemblers and even some high-level languages. See c_incl(1) for
more information.
* The c_incl utility also has a new --no-absolute-path option, to
supress scanning and reporting of such files. See c_incl(1) for more
information.
* There is a new warning added for dependencies on derived ingredients
when this information resides solely in derived cookbooks included
using the #include-cooked facility. This assists in detecting problems
which may preclude a successful ``clean'' build.
* This release adds a number of cookbook functions to the distrubuted
cookbooks. These may be used by adding a
#include "functions"
line to your cookbook. See the Cook User Guide for more information.
* This release fixes a bug where the graph walking phase ignored
interrupts until something went wrong.
* This release fixes a bug where make2cook did not correctly translate
``%'' into sematicly equivalent Cook constructs.
Release 2.1 (1997-Oct-12)
* It is possible to specify that a command is to be executed on a
specific machine or machines. This can be useful for restrictively
licensed third party software tools.
* The parallel functionality has been extended to implement a virtual
parallel machine on a LAN.
* Fingerprinting has been enhanced to be more informative, and to
adjust file modification times so that subsequest fingerprint-less runs
will not find too much to do.
* The #line directive is now available, for better diagnostics of
generated cookbooks. The __FILE__ and __LINE__ variable are also
available.
* There is now a thread-id variable, to obtain a thread-unique value
for use in generating temporary file names or variable names, etc,
which are unique to a thread.
* Added the wordlist function and the command-line-goals variable for
compatibility with GNU Make. Updated make2cook to understand them.
Release 2.0.1
* An install problem in the generated Makefile, to do with the the
manuals, has been fixed.
Release 2.0 (1997-Sep-11)
Version 2.26 (17-Jan-2005)
Development of this release was generously supported by Endocardial
Solutions, Inc.
* Parallel execution is now supported. If you have a multi-processor
machine, you can specify the number of parallel processing threads with
the -PARallel command line option, or via the [parallel_jobs] variable.
By using the [os node] function, the [parallel_jobs] variable can be
set appropriately for the host machine automatically by the cookbook.
There is a new single-thread keyword to support single threading
recipes which cannot be paralleized.
* The dependency graph is now constructed differently. This gives
exactly the same results, but the order of evaluation of recipes is a
little more random. This different graph construction is able to give
better error messages, better -Reason information, and allows the
introduction of parallel recipe evaluation if you have a multi-
processor computer.
* Recipes which use c_incl(1) to calculate their dependencies in the
ingredients section will need a small modification - they will need to
use the --Absent-Program-Ignore option. See the User Guide for more
information.
* You can now print pair-wise file dependencies by using the -PAirs
option.
* You can now print a shell script which approximates the actions cook
would take when building the targets by using the -SCript option.
* There is a new ``shallow'' recipe flag, allowing you to specify that
the targets of a recipe are required to be in the top-level directory,
not further down the search_list path.
* You may now define user-written functions in the cookbook to
supplement the built-in functions. Your functions will be called in
the same manner as built-in functions. There are new function and
return keywords to support definition of functions.
* The progress indicators produced by the -STar option now have more
detail: + means that the cook book is being read, * means that the
graph is being constructed, and # means that the graph is being walked.
Release 1.11 (1997-Jun-14)
* Fixed a bug in the pattern matching which caused %0 (when not at the
start of the pattern) to fail to match the empty string.
* The install locations have been changed slightly to conform better to
the GNU filesystem standards, and to take advantage of the additional
install location options of the configure scripts generated by GNU
Autoconf.
Release 1.10
* Error messages have been internationalized. It is now possible to
get error messages in your native language, if it is supported.
* The cook command now accepts a -no-include-cooked option, to disable
any cooking of the #include-cooked files.
* The cook -TRace option has been renamed -Reason. This is thought to
more accurately reflect what it does.
* The cook -Reason output has been changed to cite cookbook file names
and line numbers, in order to be more useful. In addition, more reason
messages carry location information.
Release 1.9
* There are new ``f77'' and ``g77'' cookbooks, to allow Fortran
sources, in addition to C sources.
* There is a new [options] function, which expands to the current
settings of the command line options. This is useful for recursive
cook directory structures. See the Reference Manual for more
information.
* There is a new ``recursive'' cookbook, to assist in constructing
recursive cook structures.
* The find_libs program now understands about shared libraries.
* A bug which made the builtin [glob] function far to generous has been
corrected.
* A bug which caused some expression evaluation errors to be ignored
has been corrected.
* The ``set update'' flag has been re-named the ``set time-adjust''
flag, to more closely describe what it does. The old name will
continue to work indefinitely.
* There is a new ``set time-adjust-back'' flag, which sets recipe
target times to be exactly one (1) second younger than the youngest
ingredient. This is usually an adjustment into the recent past.
Release 1.8
* The fingerprint code has been improved to work better with the
search_list functionality.
* The diagnostics have been improved when cook ``don't know how''. A
list of attempted ingredients is included in the error message.
* There is a new mkdir recipe flag. This creates recipe target
directories before the recipe body is run. See the Reference Manual
for more information.
* There is a new unlink recipe flag. This unlinks recipe targets
before the recipe body is run. See the Reference Manual for more
information.
* There is a new recurse recipe flag. This overrides the infinite loop
recipe heuristic, allowing recipes to recuse upon themselves if one of
their ingredients matches one of their targets. See the Reference
Manual for more information.
Release 1.7
* The AIX code to handle archive files has been fixed.
* The fingerprint code now works on 64-bit systems.
Release 1.6
* Fixed a bug in the leading-dot removal code, and added an option to
make it user-settable. Fixed a bug in the search_path depth code.
Release 1.5
* The c_incl program now correctly prints the names of absent include
files, causing them to be cooked correctly in a greater number of
cases.
* Recipes with no ingredients are now only applied if the target is
absent. To still use the previous behaviour, use the "set force"
clause on the recipe.
* It is now possible to supplement the last-modified time with a
fingerprint, so cook does even fewer unnecesary recompilations than
before. Put the statement
set fingerprint;
somewhere near the top of your Howto.cook file for this to be the
default for your project.
* There is a new form of include directive:
#include-cooked filename...
When files are included in this way, cook will check to make sure they
are up-to-date. If not, they will be cooked, and then cook will start
again and re-read the cookbook. This is most often used for
maintaining include-dependency files.
* Cook now configured using a program called configure, distributed
with the package. The configure program is generated by GNU Autoconf.
See the BUILDING file for more details.
* The semantics of search_list have been improved. It is now
guaranteed that when ingredients change they result in targets earlier
in the search_list being updated.
* There is now a make2cook translator, to translate Makefile files into
Howto.cook files. Most of the GNU Make extensions are understood.
There is no exact semantic mapping between make and cook, so manual
editing is sometimes required. See make2cook(1) for more information.
* Cook now understands archive member references, in the same format as
used by make, et al. Archive member references benefit from stat
caching and fingerprinting, just as normal files do.
Release 1.4
* The cook program is now known to work on more systems. Most changes
were aimed at improving portability, or avoiding problems specific to
some systems.
* The GNU long option name convention is now understood. Option names
for cook were always long, so this mostly consists of ignoring the
extra leading '-'. The "--foo=bar" convention is also understood for
options with arguments.
* Tests which fail now tell you what it was they were testing for.
This will give the user some idea of what is happening.
