77 <para>Prevents BitBake from processing recipes and recipe append files.
78 You can use the <filename>BBMASK</filename> variable to "hide"
79 these <filename>.bb</filename> and <filename>.bbappend</filename> files.
80 BitBake ignores any recipe or recipe append files that match the expression.
81 It is as if BitBake does not see them at all.
82 Consequently, matching files are not parsed or otherwise used by
83 BitBake.</para>
84 <para>The value you provide is passed to python's regular expression compiler.
85 For complete syntax information, see python's documentation at
86 <ulink url='http://docs.python.org/release/2.3/lib/re-syntax.html'></ulink>.
87 The expression is compared against the full paths to the files.
88 For example, the following uses a complete regular expression to tell
89 BitBake to ignore all recipe and recipe append files in the
90 <filename>.*/meta-ti/recipes-misc/</filename> directory:
91 <literallayout class='monospaced'>
92 BBMASK = ".*/meta-ti/recipes-misc/"
93 </literallayout></para>
94 <para>Use the <filename>BBMASK</filename> variable from within the
95 <filename>conf/local.conf</filename> file found
96 in the Yocto Project build directory.</para>
