+    wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.18.0/install.sh | bash

Author	SHA1	Message	Date
Jordan Harband	5f5eb47f14	v0.18.0	2014-11-05 10:59:59 -08:00
Jordan Harband	d09b84de3c	Ensure that a system has `manpath` before invoking it. Closes #531, fixes #557.	2014-11-02 13:54:54 -08:00
Jordan Harband	4b6075e29b	Merge pull request #568 from mklement0/fix_make_file Fixed Urchin invocation problem in zsh and dash. Makefile "future-proofed" to take advantage of true cross-shell testing with Urchin, once available.	2014-11-02 13:43:28 -08:00
Michael Klement	781f72c9c8	Makefile now makes use of the `-s <shell>` option for Urchin, IF it is available, for true cross-shell testing. Conversely, a warning is issued if it is missing, because that implies that no actual cross-shell testing will take place. Also, the shell command that determines the set of available test suites is now POSIX-compliant.	2014-11-01 02:18:10 -04:00

Jordan Harband	fc17aaafb1	Merge pull request #541 from mklement0/fix_make_file Makefile enhanced to error out with instructions if invoked without a target.	2014-10-30 10:23:37 -07:00
Michael Klement	ac912afc4c	Many makefile enhancements (support for direct invocation, instructions if invoked without target, release mechanism improved), package.json scripts now invoke the makefile. - Using `npm test` and `npm run …` scripts defined in package.json now invokes the makefile and runs the test with the same shell that npm was invoked from. - The makefile can now be invoked directly - supporting utilities from locally installed npm packages are automatically discovered. - Invoking the makefile without a target errors out with a hint. - Shell-specific test targets are now named 'test-<shell>'. - Both 'test-<shell>' targets and the all-shells 'test' target now run all test suites by default. - On `make TAG=<new-version> release` there must be no uncommitted changes. '<new-version>' can now also be one of the following increment specifiers: 'patch', 'minor', 'major'. - It is ensure that <new-version>, if not an increment specifier, is a valid semver version number that is higher than the previous release's. - The previous release tag is now located with a pattern so as to exclude tags that aren't version numbers. - Switched from lightweight to annotated tags for releases.	2014-10-30 00:13:22 -04:00

Jordan Harband	fc16d20766	Merge pull request #537 from ljharb/add_stable_unstable_aliases Add stable & unstable aliases. Fixes #336. With these changes, the following `nvm` commands will now support "stable" and "unstable" default/implicit aliases: - `ls`/`list` - `use` - `alias` - `run` - `exec` - `uninstall` - `copy-packages` For these, "stable" will be the latest even minor version that's locally installed; "unstable" will be the latest odd minor version that's locally installed. In addition, `nvm ls-remote` and `nvm install` will accept the same implicit aliases, however, these will actually call nodejs.org and output the latest even and odd minor versions available for installation. `nvm alias stable foo` and `nvm alias unstable foo` will override the default/implicit aliases. `nvm alias` output will reflect this by showing "(default)" when the alias is not user-defined.	2014-09-29 21:35:44 -07:00
