<span id="Configurations-2"></span><h3 class="section">9.1 Configurations</h3>
|
|
|
|
|
|
|
|
<p>Configurations specify mappings from input locations to output locations.
|
|
Once again we rely on the XDG base directory specification for configuration.
|
|
See <a href="Controlling-where-ASDF-searches-for-systems.html">XDG base directory</a>.
|
|
</p>
|
|
<ol>
|
|
<li> Some hardcoded wrapping output translations configuration may be used.
|
|
This allows special output translations (or usually, invariant directories)
|
|
to be specified corresponding to the similar special entries in the source registry.
|
|
|
|
</li><li> An application may explicitly initialize the output-translations
|
|
configuration using the Configuration API
|
|
in which case this takes precedence.
|
|
(see <a href="Controlling-where-ASDF-saves-compiled-files.html">Configuration API</a>.)
|
|
It may itself compute this configuration from the command-line,
|
|
from a script, from its own configuration file, etc.
|
|
|
|
</li><li> The source registry will be configured from
|
|
the environment variable <code>ASDF_OUTPUT_TRANSLATIONS</code> if it exists.
|
|
|
|
</li><li> The source registry will be configured from
|
|
user configuration file
|
|
<samp>$XDG_CONFIG_DIRS/common-lisp/asdf-output-translations.conf</samp>
|
|
(which defaults to
|
|
<samp>~/.config/common-lisp/asdf-output-translations.conf</samp>)
|
|
if it exists.
|
|
|
|
</li><li> The source registry will be configured from
|
|
user configuration directory
|
|
<samp>$XDG_CONFIG_DIRS/common-lisp/asdf-output-translations.conf.d/</samp>
|
|
(which defaults to
|
|
<samp>~/.config/common-lisp/asdf-output-translations.conf.d/</samp>)
|
|
if it exists.
|
|
|
|
</li><li> The source registry will be configured from
|
|
system configuration file
|
|
<samp>/etc/common-lisp/asdf-output-translations.conf</samp>
|
|
if it exists.
|
|
|
|
</li><li> The source registry will be configured from
|
|
system configuration directory
|
|
<samp>/etc/common-lisp/asdf-output-translations.conf.d/</samp>
|
|
if it exists.
|
|
|
|
</li></ol>
|
|
|
|
<p>Each of these configurations is specified as a SEXP
|
|
in a trivial domain-specific language (see <a href="Configuration-DSL.html">Configuration DSL</a>).
|
|
Additionally, a more shell-friendly syntax is available
|
|
for the environment variable (see <a href="Shell_002dfriendly-syntax-for-configuration.html">Shell-friendly syntax for configuration</a>).
|
|
</p>
|
|
<p>When processing an entry in the above list of configuration methods,
|
|
ASDF will stop unless that entry
|
|
explicitly or implicitly specifies that it
|
|
includes its inherited configuration.
|
|
</p>
|
|
<p>Note that by default, a per-user cache is used for output files.
|
|
This allows the seamless use of shared installations of software
|
|
between several users, and takes files out of the way of the developers
|
|
when they browse source code,
|
|
at the expense of taking a small toll when developers have to clean up
|
|
output files and find they need to get familiar with output-translations
|
|
first.<a id="DOCF15" href="Output-Configurations.html#FOOT15"><sup>15</sup></a>
