Suggested feature options
|
||
|
|
=========================
|
||
|
|
|
||
|
|
* Use the default memory management settings: although reference counting
|
||
|
|
increases heap header size, it also reduces memory usage fluctuation
|
||
|
|
which is often more important than absolute footprint.
|
||
|
|
|
||
|
|
* Reduce error handling footprint with one or more of:
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_AUGMENT_ERRORS``
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_TRACEBACKS``
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_VERBOSE_ERRORS``
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_PC2LINE``
|
||
|
|
|
||
|
|
* If you don't need the Duktape-specific additional JX/JC formats, use both
|
||
|
|
``DUK_OPT_NO_JX`` and ``DUK_OPT_NO_JC``.
|
||
|
|
|
||
|
|
* Features borrowed from Ecmascript E6 can usually be disabled:
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_ES6_OBJECT_SETPROTOTYPEOF``
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_ES6_OBJECT_PROTO_PROPERTY``
|
||
|
|
|
||
|
|
- ``DUK_OPT_NO_ES6_PROXY``
|
||
|
|
|
||
|
|
* If you don't need regexp support, use ``DUK_OPT_NO_REGEXP_SUPPORT``.
|
||
|
|
|
||
|
|
* Duktape debug code uses a large, static temporary buffer for formatting
|
||
|
|
debuglog lines. Use e.g. ``-DDUK_OPT_DEBUG_BUFSIZE=2048`` to reduce
|
||
|
|
this overhead.
