By contrast, our General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. The +General Public License applies to the Free Software Foundation's +software and to any other program whose authors commit to using it. +You can use it for your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Specifically, the General Public License is designed to make +sure that you have the freedom to give away or sell copies of free +software, that you receive source code or can get it if you want it, +that you can change the software or use pieces of it in new free +programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of a such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must tell them their rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any program or other work which +contains a notice placed by the copyright holder saying it may be +distributed under the terms of this General Public License. The +"Program", below, refers to any such program or work, and a "work based +on the Program" means either the Program or any work containing the +Program or a portion of it, either verbatim or with modifications. Each +licensee is addressed as "you". + + 1. You may copy and distribute verbatim copies of the Program's source +code as you receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice and +disclaimer of warranty; keep intact all the notices that refer to this +General Public License and to the absence of any warranty; and give any +other recipients of the Program a copy of this General Public License +along with the Program. You may charge a fee for the physical act of +transferring a copy. + + 2. You may modify your copy or copies of the Program or any portion of +it, and copy and distribute such modifications under the terms of Paragraph +1 above, provided that you also do the following: + + a) cause the modified files to carry prominent notices stating that + you changed the files and the date of any change; and + + b) cause the whole of any work that you distribute or publish, that + in whole or in part contains the Program or any part thereof, either + with or without modifications, to be licensed at no charge to all + third parties under the terms of this General Public License (except + that you may choose to grant warranty protection to some or all + third parties, at your option). + + c) If the modified program normally reads commands interactively when + run, you must cause it, when started running for such interactive use + in the simplest and most usual way, to print or display an + announcement including an appropriate copyright notice and a notice + that there is no warranty (or else, saying that you provide a + warranty) and that users may redistribute the program under these + conditions, and telling the user how to view a copy of this General + Public License. + + d) You may charge a fee for the physical act of transferring a + copy, and you may at your option offer warranty protection in + exchange for a fee. + +Mere aggregation of another independent work with the Program (or its +derivative) on a volume of a storage or distribution medium does not bring +the other work under the scope of these terms. + + 3. You may copy and distribute the Program (or a portion or derivative of +it, under Paragraph 2) in object code or executable form under the terms of +Paragraphs 1 and 2 above provided that you also do one of the following: + + a) accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of + Paragraphs 1 and 2 above; or, + + b) accompany it with a written offer, valid for at least three + years, to give any third party free (except for a nominal charge + for the cost of distribution) a complete machine-readable copy of the + corresponding source code, to be distributed under the terms of + Paragraphs 1 and 2 above; or, + + c) accompany it with the information you received as to where the + corresponding source code may be obtained. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form alone.) + +Source code for a work means the preferred form of the work for making +modifications to it. For an executable file, complete source code means +all the source code for all modules it contains; but, as a special +exception, it need not include source code for modules which are standard +libraries that accompany the operating system on which the executable +file runs, or for standard header files or definitions files that +accompany that operating system. + + 4. You may not copy, modify, sublicense, distribute or transfer the +Program except as expressly provided under this General Public License. +Any attempt otherwise to copy, modify, sublicense, distribute or transfer +the Program is void, and will automatically terminate your rights to use +the Program under this License. However, parties who have received +copies, or rights to use copies, from you under this General Public +License will not have their licenses terminated so long as such parties +remain in full compliance. + + 5. By copying, distributing or modifying the Program (or any work based +on the Program) you indicate your acceptance of this license to do so, +and all its terms and conditions. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the original +licensor to copy, distribute or modify the Program subject to these +terms and conditions. You may not impose any further restrictions on the +recipients' exercise of the rights granted herein. + + 7. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of the license which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +the license, you may choose any version ever published by the Free Software +Foundation. + + 8. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 9. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 10. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to humanity, the best way to achieve this is to make it +free software which everyone can redistribute and change under these +terms. + + To do so, attach the following notices to the program. It is safest to +attach them to the start of each source file to most effectively convey +the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + <one line to give the program's name and a brief idea of what it does.> + Copyright (C) 19yy <name of author> + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 1, or (at your option) + any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

A flat filesystem is a filesystem in +which directories do not exist. It provides an abstraction over any normal +filesystem which makes it appear as if directories do not exist. In effect, +it will automatically create directories as needed. This is create for things +like install scripts and such, as you never need to worry about the existence +of directories, just write to a file, no matter where it is. + +=head2 Comprehensive Implementation + +The implementation of File::Flat is extremely comprehensive in scope. It has +methods for all standard file interaction tasks, the -X series of tests, and +some other things, such as slurp. + +All methods are statically called, for example, to write some stuff to a file. + + use File::Flat; + File::Flat->write( 'filename', 'file contents' ); + +=head2 Use of other modules + +File::Flat tries to use more task orientated modules wherever possible. This +includes the use of L<File::Copy>, L<File::Copy::Recursive>, L<File::Remove> +and others. These are mostly loaded on-demand. + +=head2 Pruning and $AUTO_PRUNE + +"Pruning" is a technique where empty directories are assumed to be useless, +and thus empty removed whenever one is created. Thus, when some other task +has the potential to leave an empty directory, it is checked and deleted if +it is empty. + +By default File::Flat does not prune, and pruning must be done explicitly, +via either the L<File::Flat/prune> method, or by setting the second +argument to the L<File::Flat/remove> method to be true. + +However by setting the global C<$AUTO_PRUNE> variable to true, File::Flat +will automatically prune directories at all times. You should generally use +this locally, such as in the following example. + + #!/usr/bin/perl + + use strict; + use File::Flat; + + delete_files(@ARGV); + exit(); + + # Recursively delete and prune all files provided on the command line + sub delete_files { + local $File::Flat::AUTO_PRUNE = 1; + foreach my $file ( @_ ) { + File::Flat->remove( $file ) or die "Failed to delete $file"; + } + } + +=head2 Non-Unix platforms + +As of version 0.97 File::Flat should work correctly on Win32. Other +platforms (such as VMS) are believed to work, but require confirmation. + +=head1 METHODS + +=head2 exists $filename + +Tests for the existence of the file. +This is an exact duplicate of the -e function. + +=head2 isaFile $filename + +Tests whether C<filename> is a file. +This is an exact duplicate of the -f function. + +=head2 isaDirectory $filename + +Test whether C<filename> is a directory. +This is an exact duplicate of the -d function. + +=head2 canRead $filename + +Does the file or directory exist, and can we read from it. + +=head2 canWrite $filename + +Does the file or directory exist, and can we write to it +B<OR> can we create the file or directory. + +=head2 canReadWrite $filename + +Does a file or directory exist, and can we both read and write it. + +=head2 canExecute $filename + +Does a file or directory exist, and can we execute it. + +=head2 canOpen $filename + +Is this something we can open a filehandle to. Returns true if filename +exists, is a file, and we can read from it. + +=head2 canRemove $filename + +Can we remove the file or directory. + +=head2 isaText $filename + +Does the file C<filename> exist, and is it a text file. + +=head2 isaBinary $filename + +Does the file C<filename> exist, and is it a binary file. + +=head2 fileSize $filename + +If the file exists, returns its size in bytes. +Returns undef if the file does not exist. + +=head2 open [ $mode, ] $filename + +Rough analogue of the open function, but creates directories on demand +as needed. Supports most of the normal options to the normal open function. + +In the single argument form, it takes modes in the form [mode]filename. For +example, all the following are valid. + + File::Flat->open( 'filename' ); + File::Flat->open( '<filename' ); + File::Flat->open( '>filename' ); + File::Flat->open( '>>filename' ); + File::Flat->open( '+<filename' ); + +In the two argument form, it takes the following + + File::Flat->open( '<', 'filename' ); + File::Flat->open( '>', 'filename' ); + File::Flat->open( '>>', 'filename' ); + File::Flat->open( '+<', 'filename' ); + +It does not support the more esoteric forms of open, such us opening to a pipe +or other such things. + +On successfully opening the file, it returns it as an IO::File object. +Returns undef on error. + +=head2 getReadHandle $filename + +The same as File::Flat->open( '<', 'filename' ) + +=head2 getWriteHandle $filename + +The same as File::Flat->open( '>', 'filename' ) + +=head2 getAppendHandle $filename + +The same as File::Flat->open( '>>', 'filename' ) + +=head2 getReadWriteHandle $filename + +The same as File::Flat->open( '+<', 'filename' ) + +=head2 read $filename + +Opens and reads in an entire file, chomping as needed. + +In array context, it returns an array containing each line of the file. +In scalar context, it returns a reference to an array containing each line of +the file. It returns undef on error. + +=head2 slurp $filename + +The C<slurp> method 'slurps' a file in. That is it attempts to read the entire +file into a variable in as quick and memory efficient method as possible. + +On success, returns a reference to a scalar, containing the entire file. +Returns undef on error. + +=head2 write $filename, ( $content | \$content | \@content ) + +The C<write> method is the main method for writing content to a file. +It takes two arguments, the location to write to, and the content to write, +in several forms. + +If the file already exists, it will be clobbered before writing starts. +If the file doesn't exists, the file and any directories will be created as +needed. + +Content can be provided in three forms. The contents of a scalar argument will +be written directly to the file. You can optionally pass a reference to the +scalar. This is recommended when the file size is bigger than a few thousand +characters, is it does not duplicate the file contents in memory. +Alternatively, you can pass the content as a reference to an array containing +the contents. To ensure uniformity, C<write> will add a newline to each line, +replacing any existing newline as needed. + +Returns true on success, and undef on error. + +=head2 append $filename, ( $content | \$content | \@content ) + +This method is the same as C<write>, except that it appends to the end of +an existing file ( or creates the file as needed ). + +This is the method you should be using to write to log files, etc. + +=head2 overwrite $filename, ( $content | \$content | \@content ) + +Performs an atomic write over a file. It does this by writing to a temporary +file, and moving the completed file over the top of the existing file ( or +creating a new file as needed ). When writing to a file that is on the same +partition as /tmp, this should always be atomic. + +This method otherwise acts the same as C<write>. + +=head2 copy $source, $target + +The C<copy> method attempts to copy a file or directory from the source to +the target. New directories to contain the target will be created as needed. + +For example C<<File::Flat->( './this', './a/b/c/d/that' );>> will create the +directory structure required as needed. + +In the file copy case, if the target already exists, and is a writable file, +we replace the existing file, retaining file mode and owners. If the target +is a directory, we do NOT copy into that directory, unlike with the 'cp' +unix command. And error is instead returned. + +C<copy> will also do limited recursive copying or directories. If source +is a directory, and target does not exists, a recursive copy of source will +be made to target. If target already exists ( file or directory ), C<copy> +will returns with an error. + +=head2 move $source, $target + +The C<move> method follows the conventions of the 'mv' command, with the +exception that the directories containing target will of course be created +on demand. + +=head2 remove $filename [, $prune ] + +The C<remove> method will remove a file, or recursively remove a directory. + +If a second (true) argument is provided, then once the file or directory +has been deleted, the method will the automatically work its way upwards +pruning (deleting) empty and thus presumably useless directories. + +Returns true if the deletion (and pruning if requested) was a success, or +C<undef> otherwise. + +=head2 prune $filename + +For a file that has already been delete, C<prune> will work upwards, +removing any empty directories it finds. + +For anyone familiar with CVS, it is similar to the C<update -P> flag. + +Returns true, or C<undef> on error. + +=head2 truncate $filename [, $size ] + +The C<truncate> method will truncate an existing file to a particular size. +A size of 0 ( zero ) is used if no size is provided. If the file does not +exists, it will be created, and set to 0. Attempting to truncate a +directory will fail. + +Returns true on success, or undef on error. + +=head2 makeDirectory $directory [, mode ] + +In the case where you do actually have to create a directory only, the +C<makeDirectory> method can be used to create a directory or any depth. + +An optional file mode ( default 0755 ) can be provided. + +Returns true on success, returns undef on error. + +=head1 TO DO + +Function interface to be written, like +L<File::Spec::Functions>, to provide importable functions. + +There's something bigger here too, I'm not exactly sure what it is, +but I think there might be the beginnings of a unified filesystem +interface here...
