<p>When processing the environment variable
|
||
|
|
<code>ASDF_OUTPUT_TRANSLATIONS</code>:
|
||
|
|
</p><ul>
|
||
|
|
<li> ASDF will skip to the next configuration if it’s an empty string.
|
||
|
|
</li><li> ASDF will <code>READ</code> the string as an SEXP in the DSL, if it
|
||
|
|
begins with a parenthesis <code>(</code>.
|
||
|
|
</li><li> Otherwise ASDF will interpret the value as a list of directories
|
||
|
|
(see below).
|
||
|
|
</li></ul>
|
||
|
|
|
||
|
|
<p>In the directory list format,
|
||
|
|
directories should come in pairs, each pair indicating a mapping directive.
|
||
|
|
Entries are separated
|
||
|
|
by a <code>:</code> (colon) on Unix platforms (including Mac and cygwin), and
|
||
|
|
by a <code>;</code> (semicolon) on other platforms (mainly, Windows).
|
||
|
|
</p>
|
||
|
|
<p>The magic empty entry,
|
||
|
|
if it comes in what would otherwise be the first entry in a pair,
|
||
|
|
indicates the splicing of inherited configuration;
|
||
|
|
the next entry (if any) then starts a new pair.
|
||
|
|
If the second entry in a pair is empty,
|
||
|
|
it indicates that the directory in the first entry is to be left untranslated
|
||
|
|
(which has the same effect as if the directory had been repeated).
|
||
|
|
</p>
|
||
|
|
<p>For example, <code>"/foo:/bar::/baz:"</code> means:
|
||
|
|
specify that outputs for things under directory <samp>/foo/</samp>
|
||
|
|
are translated to be under <samp>/bar/</samp>;
|
||
|
|
then include the inherited configuration;
|
||
|
|
then specify that outputs for things under directory <samp>/baz/</samp> are not translated.

||
|
