NEWS

devtools 0.8.0.99
-----------------

NEW FEATURES

* Rcpp attributes are now automatically compiled during build.

MINOR FEATURES

* `check_cran` now downloads packages from cran.rstudio.com.

* `check()` now makes the CRAN version check optional, and off by default. The
  `release()` function still checks the version number against CRAN.

* In `check()`, it is optional to require suggested packages, using the
  `force_suggests` option.

BUG FIXES

* Fixed path issue when looking for Rtools on windows when registry entry is not present. (Fixes #201)

* Reloading a package that requires a forced-unload of the namespace now works.

* When reloading a package that another loaded package depends on, if there
  was an error loading the code, devtools would print out something about an
  error in `unloadNamespace`, which was confusing. It now gives more useful
  errors.

* An intermittent error in `clear_topic_index` related to using `rm()` has
  been fixed. (Thanks to Gregory Jefferis)

* `revdep()` now lists "Suggests" packages, in addition to "Depends" and
  "Imports".

* `revdep_check()` now correctly passes the `recursive` argument to `revdep()`.

* The collection of check results at the end of `check_cran()` previously did
  not remove existing results, but now it does.

devtools 0.8.0
--------------

NEW FEATURES

* `create` function makes it easier to create a package skeleton using
  devtools standards.

* `install_github()` can now install from a pull request -- it installs
  the branch referenced in the pull request.

* `install_github` now accepts `auth_user` and `password` arguments if you
  want to install a package in a private github repo. You only need to specify
  `auth_user` if it's not your package (i.e. it's not your `username`) (Fixes
  #116)

* new `dev_help` function replaces `show_rd` and makes it easy to get help on
  any topic in a development package (i.e. a package loaded with `load_all`)
  (Fixes #110)

* `dev_example` runs the examples for one in-development package. (Fixes #108)

* `build_vignettes` now looks in modern location for vignettes (`vignettes/`) 
   and warn if vignettes found in old location (`inst/doc`).  Building now 
   occurs in a temporary directory (to avoid polluting the package with
   build artefacts) and only final pdf files are copied over.

* new `clean_vignettes` function to remove pdfs in `inst/doc` that were built
  from vignettes in `vignettes/`

* `load_all` does a much much better job at simulating package loading (see
  LOADING section). It also compiles and loads C/C++/Fortran code.

* `unload()` is now an exported function, which unloads a package, trying
  harder than just `detach`. It now also unloads DLLs. (Winston Chang. Fixes
  #119)

* `run_examples` now has parameters `show`, `test`, `run` to control which of
  `\dontrun{}`, `\dontshow{}`, `\donttest{}` and `\testonly{}` are commented
  out. The `strict` parameter has been removed since it is no longer necessary
  because `load_all` can respect namespaces. (Fixes #118)

* `build()`, `check()`, `install()` etc now run R in `--vanilla` mode which
  prevents it from reading any of your site or personal configuration files.
  This should prevent inconsistencies between the environment in which the
  package is run between your computer and other computers (e.g. the CRAN
  server) (Fixes #145)

* All system R command now print the full command used to make it easier to
  understand what's going on.

PACKAGE PATHS

* `as.package` no longer uses `~/.Rpackages`.

* `as.package` provides more informative error messages when path does not
  exist, isn't a directory, or doesn't contain a `DESCRIPTION` file.

* New function `inst()` takes the name of a package and returns the installed
  path of that package. (Winston Chang. Fixes #130). This makes it possible to
  use `devtools` functions (e.g. `unload`) with regular installed packages,
  not just in-development source packages.

* New function `devtest()` returns paths to an internal testing packages
  in devtools.

LOADING

* Development packages are now loaded into a namespace environment,
  <namespace:xxxx>, and then the objects namespace are copied to the
  package environment, <package:xxxx>. This more accurately simulates
  how packages are normally loaded. However, all of the objects (not
  just the exported ones) are still copied to the package environment.
  (Winston Chang. Fixes #3, #60, and #125)

* Packages listed in Imports and Depends are now loaded into an imports
  environment, with name attribute "imports:xxxx", which is the parent
  of the namespace environment. The imports environment is in turn a
  child of the <namespace:base> environment, which is a child of the
  global environment. This more accurately simulates how packages are
  normally loaded.  These packages previously were loaded and attached.
  (Winston Chang. Fixes #85)

* The NAMESPACE file is now used for loading imports, instead of the
  DESCRIPTION file. Previously, `load_all` loaded all objects from the
  packages listed in DESCRIPTION. Now it loads packages (and, when
  when 'importfrom' is used, specific objects from packages) listed in
  NAMESPACE. This more closely simulates normal package loading. It
  still checks version numbers of packages listed in DESCRIPTION.
  (Winston Chang)

* `load_all` can now be used to properly reload devtools. It does this
  by creating a copy of the devtools namespace environment, and calling
  `load_all` from that environment. (Winston Chang)

* The `.onLoad` and `.onAttach` functions for a development package are
  now both called when loading a package for the first time, or with
  `reset=TRUE`, and the order more correctly simulates normal package
  loading (create the namespace, call `.onLoad`, copy objects to the
  package environment, and then call `.onAttach`). (Winston Chang)

* `load_all` will now throw a warning if a dependency package does not
  satisfy the version requirement listed in DESCRIPTION. (Winston Chang.
  Fixes #109)

* The package environment now has a 'path' attribute, similar to a
  package loaded the normal way. (Winston Chang)

* `load_all` now has an option `export_all`. When set to TRUE, only the
  objects listed as exports in NAMESPACE are exported. (Winston Chang)

* `load_all` now compiles C files in the /src directory. (Winston Chang)

* New functions `compile_dll()` and `clean_dll()`, which compile C/C++/
  Fortan source code, and clean up the compiled objects, respectively.
  (Winston Chang. Fixes #131)

BUG FIXES

* `load_code` now properly skips missing files. (Winston Chang)

* Add `--no-resave-data` to default build command. 

* The subject line of the email created by `release` is now "CRAN submission
  [package] [version]", per CRAN repository policy.

* `install_bitbucket` properly installs zip files of projects stored
  in Mercurial repositories. (Winston Chang. Fixes #148)

* `build` now builds vignettes because `install` does not. (Fixes #155)

INTROSPECTION

* New function `loaded_packages()`, which returns the names of packages
  that are loaded and attached.

* Packages loaded with `load_all` now store devtools metadata in their
  namespace environment, in a variable called `.__DEVTOOLS__`. This can
  be accessed with the `dev_meta` function. (Winston Chang. Fixes #128)

* `dev_mode` now stores the path it uses in option `dev_path`. That makes it
  easy for other applications to detect when it is on and to act accordingly.

* New function `parse_ns_file()`, which parses a NAMESPACE file for a
  package.

* New function `parenvs()`, which parents the parent environments
  of an object. (Winston Chang)

devtools 0.7.1
--------------

* bump dependency to R 2.15

* `load_code` now also looks for files ending in `.q` - this is not
  recommended, but is needed for some older packages

devtools 0.7
------------

INSTALLATION

* `install_bitbucket` installs R packages on bitbucket.

* `install` now uses `--with-keep.source` to make debugging a little easier.

* All remote install functions give better error messages in the case of http
  errors (Fixes #82).

* `install` has new quick option to make package installation faster, by
  sacrificing documentation, demos and multi-architecture binaries. (Fixes
  #77)

* `install_url`, `install_github` and `install_gitorious` gain a subdir
  argument which makes it possible to install packages that are contained
  within a sub-directory of a repository or compressed file. (Fixes #64)

CHECKING

* `with_debug` function temporarily sets env vars so that compilation is
  performed with the appropriate debugging flags set. Contributed by Andrew
  Redd.

* `revdep`, `revdep_maintainers` and `revdep_check` for calculating reverse
  dependencies, finding their maintainers and running `R CMD check`. 
  (Fixes #78)

* `check_cran` has received a massive overhaul: it now checks multiple
  packages, installs dependencies (in user specified library), and parse check
  output to extract errors and warnings

* `check` uses new `--as-cran` option to make checking as close to CRAN as
  possible (fixes #68)

OTHER NEW FEATURES

* devtools now uses options `devtools.path` to set the default path to use
  with devmode, and `github.user` to set the default user when installing
  packages from github.

* if no package supplied, and no package has been worked with previously, all
  functions now will try the working directory. (Fixes #87)

* on windows, devtools now looks in the registry to find where Rtools is
  installed, and does a better a job of locating gcc. (Contributed by Andrew
  Redd)

* `show_rd` passes `...` on to `Rd2txt` - this is useful if you're checking
  how build time `\Sexpr`s are generated.

* A suite of `with` functions that allow you to temporarily alter the
  environment in which code is run: `in_dir`, `with_collate`, `with_locale`,
  `with_options`, `with_path`, ... (Fixes #89)

* `release` ask more questions and randomises correct answers so you really
  need to read them (Fixes #79)

* `source_gist` now accepts default url such as "https://gist.github.com/nnn"

* New system path manipulation functions, `get_path`, `set_path`, `add_path`
  and `on_path`, contributed by Andrew Redd.

* If you're on windows, `devtools` now suppresses the unimportant warning from
  CYGWIN about the dos style file paths

BUG FIXES

* `decompress` now uses target directory as defined in the function call
  when expanding a compressed file. (Fixes #84)

* `document` is always run in a C locale so that `NAMESPACE` sort order is
  consistent across platforms.

* `install` now quotes `libpath` and build path so paths with embedded spaces
  work (Fixes #73 and #76)

* `load_data` now also loads `.RData` files (Fixes #81)

* `install` now has `args` argument to pass additional command line arguments
  on to `R CMD install` (replaces `...` which didn't actually do anything).
  (Fixes #69)

* `load_code` does a better job of reconciling files in DESCRIPTION collate
  with files that actually exist in the R directory. (Fixes #14)

devtools 0.6
------------

NEW FEATURES

* `test` function takes `filter` argument which allows you to restrict which
  tests are to be run

* `check` runs with example timings, as is done on CRAN. Run with new param
  `cleanup = F` to access the timings. 

* `missing_s3` function to help figure out if you've forgotten to export any
  s3 methods

* `check_cran` downloads and checks a CRAN package - this is useful to run as
  part of the testing process of your package if you want to check the
  dependencies of your package

* `strict` mode for `run_examples` which runs each example in a clean
  environment. This is much slower than the default (running in the current
  environment), but ensures that each example works standalone. 

* `dev_mode` now updates prompt to indicate that it's active (Thanks to Kohske
  Takahashi)

* new `source_url` function for sourcing script on a remote server via
  protocols other than http (e.g. https or ftp). (Thanks to Kohske Takahashi)

* new `source_gist` function to source R code stored in a github gist. (Thanks
  to Kohske Takahashi)

* `load_all` now also loads all package dependencies (including suggestions) -
  this works around some bugs in the way that devtools attaches the
  development environment into the search path in a way that fails to recreate
  what happens normally during package loading.

INSTALLATION

* remote installation will ensure the configure file is executable.

* all external package installation functions are vectorised so you can
  install multiple packages at time

* new `install_gitorious` function install packages in gitorious repos.

* new `install_url` function for installing package from an arbitrary url

* include `install_version` function from Jeremy Stephens for installing a
  specific version of a CRAN package from the archive.

BETTER WINDOWS BEHAVIOUR

* better check for OS type (thanks to Brian Ripley)

* better default paths for 64-bit R on windows (Fixes #35)

* check to see if Rtools is already available before trying to mess with the
  paths. (Fixes #55)

BUG FIXES

* if an error occurs when calling loading R files, the cache will be
  automatically cleared so that all files are loaded again next time you try
  (Fixes #55)

* functions that run R now do so with `R_LIBS` set to the current
  `.libPaths()` - this will ensure that checking uses the development library
  if you are in development mode. `R_ENVIRON_USER` is set to an empty file to
  avoid your existing settings overriding this.

* `load_data` (called by `load_all`) will also load data defined in R files in
  the data directory. (Fixes #45)

* `dev_mode` performs some basic tests to make sure you're not setting your
  development library to a directory that's not already an R library. (Fixes
  #25)

devtools 0.5.1
--------------

* Fix error in that was causing R commands to fail on windows.

devtools 0.5
--------------

NEW FUNCTIONS

* new `show_rd` function that will show the development version of a help
  file.

IMPROVEMENTS AND BUG FIXES

* external R commands always run in locale `C`, because that's what the CRAN
  severs do.

* `clean_source` sources an R script into a fresh R environment, ensuring that
  it can run independently of your current working environment. Optionally
  (`vanilla = T`), it will source in a vanilla R environment which ignores all
  local environment settings.

* On windows, `devtools` will also add the path to `mingw` on startup. (Thanks
  to pointer from Dave Lovell)

devtools 0.4
------------

NEW FUNCTIONS

* new `wd` function to change the working directory to a package subdirectory.

* `check_doc` now checks package documentation as a whole, in the same way
  that `R CMD check` does, rather than low-level syntax checking, which is
  done by `roxygen2. DESCRIPTION checking has been moved into `load_all`.
  `check_rd` has been removed.

* `build` is now exported, and defaults to building in the package's parent
  directory. It also gains a new `binary` parameter controls whether a binary
  or a source version (with no vignettes or manuals) is built. Confusingly,
  binary packages are built with `R CMD INSTALL`.

* `build_win` sends your package to the R windows builder, allowing you to
  make a binary version of your package for windows users if you're using
  linux or a max (if you're using windows already, use `build(binary = T)`)

IMPROVEMENTS AND BUG FIXES

* if using `.Rpackages` config file, default function is used last, not first.

* on Windows, `devtools` now checks for the presence of `Rtools` on startup,
  and will automatically add it to the path if needed.

* `document` uses `roxygen2` instead of `roxygen`. It now loads package
  dependency so that they're available when roxygen executes the package
  source code.

* `document` has new parameter `clean` which clears all roxygen caches and
  removes all existing man files. `check` now runs `document` in this mode.

* `dev_mode` will create directories recursively, and complain if it can't
  create them.  It should also work better on windows.

* `install_github` now allows you to specify which branch to download, and
  automatically reloads package if needed.

* `reload` now will only reload if the package is already loaded.

* `release` gains `check` parameter that allows you to skip package check (if
  you've just done it.)

* `test` automatically reloads code so you never run tests on old code 

devtools 0.3
------------

* new `bash()` function that starts bash shell in package directory. Useful if
  you want to use git etc.

* removed inelegant `update_src()` since now superseded by `bash()`

* fix bug in ftp upload that was adding extraneous space

* `build` function builds package in specified directory. `install`, `check`
  and `release` now all use this function.

* `build`, `install`, `check` and `release` better about cleaning up after
  themselves - always try to both work in session temporary directory and
  delete any files/directories that they create

devtools 0.2
------------

* `install_github` now uses `RCurl` instead of external `wget` to retrieve
  package. This should make it more robust wrt external dependencies.

* `load_all` will skip missing files with a warning (thanks to suggestion from Jeff Laake)

* `check` automatically deletes `.Rcheck` directory on successful completion

* Quote the path to R so it works even if there are spaces in the path.

devtools 0.1
------------

* Check for presence of `DESCRIPTION` when loading packages to avoid false
  positives

* `install` now works correctly with `devel_mode` to install packages in your
  development library

* `release` prints news so you can more easily check it

* All `R CMD xxx` functions now use the current R, not the first R found on
  the system path.
