go-script-bash v1.7.0

This is a minor update to add a few test helpers, _GO_PLATFORM variables and the ./go goinfo command, several file system processing modules, and a handful of project improvements.

The ./go script: a unified development environment interface

Source: https://github.com/mbland/go-script-bash

A ./go script aims to abstract away many of the steps needed to develop (and sometimes deploy) a software project. It is a replacement for READMEs and other documents that may become out-of-date, and when maintained properly, should provide a cohesive and discoverable interface for common project tasks.

The ./go script idea came from Pete Hodgson's blog posts In Praise of the ./go Script: Part I and Part II.

Note: The ./go script concept is completely unrelated to the Go programming language, though the Go language's go command encapsulates many common project functions in a similar fashion.

What's new in this release

All of the issues and pull requests for this release are visible in the v1.7.0 milestone.

./go null

The ./go null command verifies that the framework is installed and functioning properly (#190).

New test helpers

There are a few powerful new test helper functions:

  • create_forwarding_script (#192, #195): Used to create a wrapper in BATS_TEST_BINDIR to make a system program accessible while restricting PATH via PATH="$BATS_TEST_BINDIR".
  • restore_programs_in_path (#196): Allows a single call to remove multiple command stub scripts.
  • run_test_script (#196): Creates and runs a test script in one step, so that create_bats_test_script and run need not be called separately.
  • run_bats_test_suite (#196): A specialized version of run_test_script specifically for generating and running Bats test cases.
  • run_bats_test_suite_in_isolation (#196): An even more specialized version of run_bats_test_suite to ensure that PATH is restricted to BATS_TEST_BINDIR and the Bats libexec/ directory within the suite.
  • lib/bats/background-process (#197): Helpers for managing and validating background processes.
  • skip_if_none_present_on_system (#198): Skips a test if none of the specified system programs are available.

_GO_PLATFORM vars and ./go goinfo command

The lib/platform module introduced in #200 provides an interface to detect on which system the script is running. Is parses /etc/os-release if it's available; otherwise uses OSTYPE, uname -r, and sw_vers -productVersion (on macOS).

The ./go goinfo command introduced in #216 uses the lib/platform module to print version information about the go-script-bash framework, Bash, and the host operating system:

$ ./go goinfo

_GO_CORE_VERSION:         v1.7.0
BASH_VERSION:             4.4.12(1)-release
OSTYPE:                   darwin16.3.0
_GO_PLATFORM_ID:          macos
_GO_PLATFORM_VERSION_ID:  10.13

File system processing modules

Introduced in #201, @go.native_file_path_or_url from lib/portability converts a file system path or file:// URL to a platform-native path. This is necessitated by MSYS2, especially Git for Windows, which has system programs which expect Windows-native paths as input, or whose output will reflect Windows-native paths. It's used in several tests, as well as the ./go get command.

The lib/path module introduced in #203 and #206 includes functions to canonicalize file system paths, resolve symlinks, and walk directories.

lib/fileutil from #204 and updated in #207 and #210 contains functions to safely create directories (with extensive error reporting), to collect all the regular files within a directory structure, to safely copy all files into a new directory structure, and to safely mirror directories using tar.

lib/diff from #205 contains functions to log or edit differences between files and directory trees.

lib/archive from #211 contains the @go.create_gzipped_tarball convenience function to easily and safely create .tar.gz archive files.

Project improvements

The project now contains a GitHub issue and pull request templates, a GitHub CODEOWNERS file, and an Appveyor build to ensure Windows compatibility. See:

Bug fixes

  • stub_program_in_path (#194): Now ensures that new stubs are passed to hash. Previously, if a command had already been invoked, Bash would remember its path, and ignore the new stub.
