Fuse::Template - Mount a directory with templates.

0.0201

sudo might be optional.

Example SQLite:

 $ sudo fuse-template
   --root /path/to/templates \
   --mountpoint /path/to/mountpoint \
   --schema dbi:SQLite:path/to/db \
   ;

Example MySQL:

 $ sudo fuse-template
   --root /path/to/templates \
   --mountpoint /path/to/mountpoint \
   --schema "dbi:mysql:database=MyDB;host=127.1;port=3006 user pass" \
   ;

See DBI for possible --schema formats.

This needs to be done manually for now. (Patches are welcome!)

 sudo umount /path/to/mountpoint;

IMPORTANT! Version 0.02 of Fuse::Template breaks backward compat by using the new "v7" naming convention from DBIx::Class::Schema::Loader. Set the SCHEMA_LOADER_BACKCOMPAT environment variable, if you want the old behavior.

The idea with this project is to auto-maintain password files, and other plain text files for different systems, with data from a database.

See examples/ in this distribution for templates.

Example file system structure:

 root/               -> mountpooit/
 root/somefile       -> mountpoint/somefile
 root/foo.tt         -> mountpoint/foo
 root/bar/baz.txt.tt -> mountpoint/bar/baz.txt

somefile is accessible directly at mountpoint. Template files (.tt) are parsed and the output is accessible on mountpoint side. This is done using Template::Toolkit.

Files in mountpoint are read-only for now.

Here is an example template:

 root = [% self.root %]
 [% rs = schema.resultset('MyTable') %]
 [% rs = MyTable; # same as schema.resultset(...) %]
 [% WHILE (row = rs.next) # get next row in resultset %]
 col_name = [% row.col_name # retrieve column data %]
 [% END %]

See DBIx::Class for information on how to use the schema object, and DBIx::Class::Resultset on how to select data and more...

Available variables:

 root
 mountpoint
 mountopts
 self # this object
 schema # DBIx::Class object
 + all resultsetset/tables

Resultset use this naming convention to convert tablenames:

    Table Name  | Moniker Name
    ---------------------------
    luser       | Luser
    luser_group | LuserGroup
    luser-opts  | LuserOpts

See moniker_map in DBIx::Class::Schema::Loader for details

On ubuntu:

    $ sudo aptitude install libfuse-perl
    $ wget -q http://xrl.us/cpanm | perl - --sudo Fuse::Template

See App::cpanminus if you are curious about the "wget" command.

 $object = $self->root;

$object must be stringified to path where templates/files are located. $object must follow the same API as Fuse::Template::Root.

Can be set in constructor as:

 root => \%constructor_args
 root => $path_to_root

%constructor_args can override defaults, while $path_to_root will only override path attribute in root-object.

 $path = $self->mountpoint;

Path to where the filesystem should be mounted.

 $str = $self->mountopts;

Example mount option: "allow_other"

 $dbic_object = $self->schema;

Can be set in constructor as:

 schema => \%args
 schema => "$dsn $username $password"

See Fuse::Template::Schema for details.

 $bool = $self->debug;

Enable/disable debug output from Fuse. Default is disabled.

 $real_path = $self->find_file($virtual_path);

Returns path to the file in root path.

 $bool = $self->log($level => $format => @args);
