1.0.3

New Features

  • Added %context directive, which allows included scripts to use their native working directories (thanks chenguo)

Bug Fixes

1.0.2

New Features

  • If you have no SHELL environment variable when running a command, we now default to /bin/sh
  • Added support for environment variable DRAKE_JAR to let you store drake elsewhere

Bug Fixes

  • Fix handling of optional input files
  • Fix various interactions between method definitinos and %include directives

1.0.1

New Features

  • Optional input files #181

Bug Fixes

  • drake.log was sometimes put in the wrong directory #183

1.0.0

New Features

  • Support symbolic link even if DRAKE_HOME is not defined
  • Overhauled drake script to support install and upgrades

Maintenance / Generic Improvements

  • Trimmed dependencies: Removed Factual API features; Upgraded to c4 version 0.2.1 which dropped 3rd party API dependencies.
  • Upgraded to Clojure 1.6.0

0.1.7

New Features

  • Created core/DEFAULT-TARGETV constant; use in clj_frontend
  • Added with-ns macro to support c4 runtime dependency resolution
  • Added support for quoting filenames, to permit filenames that otherwise look like drake rules
  • Added --var x=y --var a=b syntax, as better version of --vars x=y,a=b
  • Added --graph option to help visualize a workflow
  • Added handy drake script for convenience and better customized hadoop client version.

Bug Fixes

  • Allow unindented blank lines in step definitions, as per #72
  • BASE var default is now the workflow directory rather than empty string, as per #148
  • Prefixed (HDFS, S3) paths are now treated as absolute/off-base, as per #157
  • Fix some bugs related to parsing, and to over-optimistically running shell expansions

Maintenance / Generic Improvements

  • Made it easier to run drake from inside a clojure repl/nrepl session (removing System/exit calls)
  • Generally improved error-message output, esp. removing repetitive or useless spam and adding line/column number to parse errors
  • Upgraded to Clojure 1.6
  • Numerous performance improvements, which may actually be noticeable on large workflows

0.1.6

0.1.5

  • bugfix: #98 --help now doesn't run workflow (thanks marshallshen)
  • Upgrade to c4 0.2.0, which no longer bundles the Facebook API
  • Basic functionality working for Windows sytems, specifically, Windows 8/command shell.
  • bugfix: #11 FileSystem plugins get wired up properly (thanks derenrich)
  • Initial fix for #118 to handle quotes better in shell commands (thanks myronahn)
  • Fixes and documentation for core.run-workflow
  • Add node (Javascript) protocol (thanks arowla)
  • Upgrade c4 to version 0.2.0, which drops bundling of Facebook Places API support
  • Supprot for command line var regex

0.1.4

  • Added support for async execution of steps via --jobs (thanks guillaume and myronahn). See Async Execution of Steps
  • Added support for plugins via --plugins. See Plugins wiki page
  • Internal cleanup of drake.fs design (thanks stanistan)

0.1.3

  • Default workflow filename changed from workflow.d to Drakefile
  • Significant parsing speed up for large files (>x10)
  • BASE variable:
  • bugfix: wasn't being picked up if set through environment
  • bugfix: wasn't correctly working with := (#14)
  • --base command-line flag supported
  • Added preference for getting Hadoop config location from HADOOP_HOME environment variable. Addresses #35
  • Added support for S3 (thanks howech) (#60)

0.1.2

  • = are now allowed in filenames
  • : are now allowed in filenames (Drake will default to local file system instead of issuing "invalid filesystem" error, i.e. bad:name -> file:bad:name)
  • CLI changes:
  • CLI is now getopt-compliant (i.e. one could do drake -aw my-workflow.d)
  • -d doesn't work any more for debugging info: only --debug (-d reserved for future use)
  • --debug prints much less info now, --trace added for more verbose output
  • Added checking for conflicting options (i.e. --preview vs --print).
  • Help is now printed nicely
  • Added --step-delay to specify the amount of time, in milliseconds, to wait after each step. Should help with desynchronized filesystems.
  • bugfixes: #34

0.1.1

  • Drake now works with Drip which allows to bring down startup time essentially to zero in most cases.
  • Added support for R ("R" protocol). See resources/regtest/regtest_interpreters.d for usage example.
  • Added --preview command-line option, which prints the same report of targets predicted to be built, but immediately exits afterwards instead of asking for user confirmation.
  • You can now use Drake from Clojure REPL by calling run-workflow function.

0.1.0

  • Initial release!
