ProjectTemplate 0.6 (2014-10-06)

Includes all modifications from v0.5-3 and v0.5-2.

ProjectTemplate 0.5-3

Packages required for loading data sources are attached to the search path (with a warning) only if the new compatibility setting attach_internal_libraries is set to TRUE. Attaching packages to the search path seems to be unnecessary to achieve proper functionality, but users might rely on this behavior, and so this is the default for migrated projects but turned off for new projects (#104).

ProjectTemplate 0.5-2

Bug fixes

Fixed error message when require.package is called from an anonymous function and fails to load a package. (Using deparse(nlines = 1) now.)

Features

Added function .add.extension(). This allows users to create custom readers for extensions, either locally in a project or as packages.
The configuration now stores the version of ProjectTemplate in the version field (#90).
New function migrate.project() that allows upgrading a project to the current version of ProjectTemplate (#90, #121).
New parameter override.config to load.project() and reload.project() allows substitution of individual configuration items (#76).
Can use mustache style templating in SQL calls to access project data structures (#50).
Support passwordless connection to postgresql databases (#115).
Configuration entries that start with a hash (#) are silently ignored (#74).
New variables default.config and new.config that store the default configuration used for missing configuration items or for a new project (#76, #89).
Missing but required directories are now created (with a warning) (#76).
Missing entries in the configuration file, or a missing configuration file, are substituted by defaults (with a warning). Extra entries are ignored (with a warning) (#76).
All logical configuration options are now stored as Boolean values instead of 'on'/'off'. Input values other than 'on'/'off' are converted using as.logical, invalid values result in an error (#76).

Internal

Dropped dependency on Defaults package (#100).
Suppress warnings in tests (#111).
Fix CRAN check issues (#117).
Improved presentation of available readers in documentation (#119).

ProjectTemplate 0.5-1 (2014-03-17)

Bug fixes

Restore compatibility to R 2.15.3 by avoiding use of the no.. parameter to list.files() in our create.project() function.

ProjectTemplate 0.5 (2014-03-13)

Features

New function get.project() to access project.info.
Attempting to load a missing package when reading data will lead to a user-friendly error message (#26).

Add new function .add.extension. This allows users to create custom readers for extensions, either locally in a project or as packages (#59).

Internal

Fix CRAN warnings concerning use of ProjectTemplate::: qualification (#56).
Fix CRAN warnings concerning assignments to .GlobalEnv.
Updated author information in DESCRIPTION file (#40).
Store templates for empty projects in tar files instead of storing the entire directory structure per CRAN request and to avoid having to build with the --keep-empty-dirs switch (#41).
