Build Status

Automatically generate boilerplate comments and code for new files with a single command.

Install

cd ~/bin
git clone git@github.com:mbrukman/autogen.git
echo 'alias autogen=~/bin/autogen/autogen' >> ~/.bash_profile
source ~/.bash_profile

Editor support

For details on adding Autogen support to your editor, please see the editors directory.

Usage

autogen -c [copyright holder] -l [license] [filename]

Modify an existing file in-place:

autogen -i [...other params as above...]

Bulk update many existing files in-place:

find . -type f -name \*.sh -exec autogen -i --no-top-level-comment [options...] {} \;

The flag --no-top-level-comment avoids adding a comment such as:

/* TODO: High-level file comment */

because either some or all of the files have such a top-level comment, or if they don't, you probably wouldn't want to have to manually add or delete at this time, if you're just trying to add the license header in bulk.

To get a list of supported licenses, or to see the full set of flags, run autogen with no parameters.

File type or language is determined based on the full filename or extension, as appropriate. See autogen for a list of recognized file types.

The flag --no-code skips adding boilerplate code to source files.

The flag --no-runline skips adding runline to source files.

Sample outputs:

Developing

To add a new file type or feature, change autogen and add several files to the tests/testdata directory, namely:

  • <feature>.in - the input file containing command-line args to pass to autogen
  • <feature>.out - expected stdout for the test
  • <feature>.err - expected stderr for the test

To generate the *.out and *.err files automatically, just add the *.in files and run make regen. Then, examine the resulting *.out and *.err files.

Other custom tests can be added as separate scripts in the tests directory. If the file has the suffix _test.sh, it will be automatically picked up by tests/run_all_tests.sh script, which means that make test will automatically run it without any other changes.

Be sure to also add an entry for it in tests/BUILD file for Bazel to be able to run it as well, including appropriate dependencies on any data files it may need.

Testing

You have two options:

  • via Bazel: bazel test //...
  • via Make: make test

Bazel is typically faster, especially when rerunning tests, due to built-in caching.
