ttree - template tree processor


    ttree [options] [files]


The ttree script is used to process entire directory trees containing template files. The resulting output from processing each file is then written to a corresponding file in a destination directory. The script compares the modification times of source and destination files (where they already exist) and processes only those files that have been modified. In other words, it is the equivalent of 'make' for the Template Toolkit.

It supports a number of options which can be used to configure behaviour, define locations and set Template Toolkit options. The script first reads the .ttreerc configuration file in the HOME directory, or an alternative file specified in the TTREERC environment variable. Then, it processes any command line arguments, including any additional configuration files specified via the -f (file) option.

A typical .ttreerc file might look like this:

    src    = /home/abw/websrc/doc
    dest   = /home/abw/public_html
    lib    = /home/abw/websrc/lib
    lib    = /usr/local/templates/lib
    cfg    = /home/abw/.ttree
    ignore = \b(CVS|RCS)\b
    ignore = ^#
    copy   = \.(gif|png)$ 
    accept = \.[ah]tml$

The src option indicates a directory containing the template files to be processed. A list of files may be specified on the command line and each will be processed in turn, writing the generated output to a corresponding file in the dest directory. If no files are explicitly named then all files in the src directory will be processed. The -r (recurse) option will also cause sub-directories to be searched for files. A source file is only processed if it has a later modification time than any corresponding destination file. Files will always be processed, regardless of modification times, if they are named explicitly on the command line, or the -a (all) option is used.

The lib option may be specified any number of times to indicate directories in which the Template Toolkit should look for other template files (INCLUDE_PATH) that it may need to INCLUDE or PROCESS, but don't represent complete documents that should be processed in their own right (e.g. headers, footers, menu). The cfg directory specifies the location of additional configuration files that may be loaded via the -f option.

The ignore, copy and accept options are used to specify Perl regexen to filter file names. Files that match any of the ignore options will not be processed. Remaining files that match any of the copy regexen will be copied to the destination directory. Remaining files that then match any of the accept criteria are then processed via the Template Toolkit. If no accept parameter is specified then all files will be accepted for processing if not already copied or ignored.

Additional options may be used to set Template Toolkit parameters. For example:

   pre_process  = header
   post_process = footer
   perl5lib     = /home/abw/lib/perl5

See ttree --help for a summary of options.
