The main nodejs flavor is "npm", which is to be used to
lint/test and the publication of an official npm
package -- and by design it has dependencies on mocha,
eslint, etc.
A new flavor "dig" has been created with minimal
dependencies and which purpose is to easily allow to
write specialized code to investigate local code changes
in uBO -- and it's not meant for publication.
Consequently, "make nodejs" has been replaced with
"make npm", and a new "dig" target has been added to the
makefile, to be used for instrumenting local code changes
for investigation purpose.
For clients who may wish to persist the intermediate compiled form
in order to be able to skip costly parsing operation when the
list is fed to the static network filtering engine.
In the static network filtering engine (snfe), the
compiling-related code was spread across two classes.
This commit makes it so that all the compiling-related
code is in FilterCompiler class, which clear purpose is
to compile raw filters into a form which can be persisted
and later fed to the snfe with no parsing overhead.
To compile raw static network filter, the new approach is:
snfe.createCompiler(parser);
Then for each single raw filter to compile:
compiler.compile(parser, writer);
The caller is responsible to keep a reference to the
compiler instance for as long as it is needed. This removes
the need for the clunky code used to keep an instance of
compiler alive in the snfe.
Additionally, snfe.tokenHistograms() has been moved to
benchmarks.js, as it has no dependency on the snfe, it's
just a utility function.
