Specify compile definitions in profile files to use when compiling the jerry-core
target.
The default profile is es.next
which enables all of the currently implemented features.
You can specify the profile for the build system in the following ways:
- with absolute path
- with a name (this options selects profiles/$(name).profile file)
Only single line options are allowed in the profile file. Any line starting with hash-mark is ignored. Semicolon character is not allowed.
If you want to use a predefined profile, run the build script as follows (assuming that you are in the project root folder):
./tools/build.py --profile=minimal
Alternatively, if you want to use a custom profile at
/absolute/path/to/my.profile
:
# Disable not needed features
JERRY_BUILTIN_CONTAINER=0
JERRY_BUILTIN_DATAVIEW=0
JERRY_BUILTIN_TYPEDARRAY=0
Run the build script as follows (assuming that you are in the project root folder):
./tools/build.py --profile=/absolute/path/to/my.profile
Set FEATURE_PROFILE option to one of the following values:
- the profile with absolute path
- name of the profile (which needs to exist in the
profiles
folder)
In JerryScript all of the features are enabled by default, so an empty profile file turns on all of the available ECMA features.
The defines can have a value of 0
or 1
. If for whatever reason one of them are not defined, it is treated as if it were
defined to 1
.
