These examples assume a working directory of +'foo': +<table> +<tr> + <td><code>:foo</code></td> + <td>Equivalent to '//foo:foo'.</td> +</tr> +<tr> + <td><code>bar:wiz</code></td> + <td>Equivalent to '//foo/bar:wiz'.</td> +</tr> +<tr> + <td><code>bar/wiz</code></td> + <td>Equivalent to: + '//foo/bar/wiz:wiz' if foo/bar/wiz is a package, + '//foo/bar:wiz' if foo/bar is a package, + '//foo:bar/wiz' otherwise. + </td> +</tr> +<tr> + <td><code>bar:all</code></td> + <td>Equivalent to '//foo/bar:all'.</td> +</tr> +<tr> + <td><code>:all</code></td> + <td>Equivalent to '//foo:all'.</td> +</tr> +<tr> + <td><code>...:all</code></td> + <td>Equivalent to '//foo/...:all'.</td> +</tr> +<tr> + <td><code>...</code></td> + <td>Equivalent to '//foo/...:all'.</td> +</tr> +<tr> + <td><code>bar/...:all</code></td> + <td>Equivalent to '//foo/bar/...:all'.</td> +</tr> +</table> +</p> + +<p> +By default, directory symlinks are followed for recursive target patterns, +except those that point to under the output base, such as the convenience +symlinks that are created in the root directory of the workspace. +</p> + +<p> +In addition, Blaze does not follow symlinks when evaluating recursive target +patterns in any directory that contains a file named as follows: +<pre> +DONT_FOLLOW_SYMLINKS_WHEN_TRAVERSING_THIS_DIRECTORY_VIA_A_RECURSIVE_TARGET_PATTERN +</pre> +</p> + +<p> +Target patterns may be preceded by a single dash ('<code>-</code>'), in which +case Blaze subtracts them from the set of targets accumulated by preceding +patterns. Note that this means <em>order matters</em>. In order to pass negative +target patterns, you need to use '--' as an argument to prevent Blaze from +interpreting it as an option, e.g.: +<pre> +blaze build -- foo/... -foo/contrib/... +</pre> +Note that Blaze may still build targets matched by a negative target pattern due +to dependencies, and may also load the corresponding BUILD files, even if the +targets are never built. +</p> + + + |
