So far, PEG.js was exported in a "PEG" global variable when no module
loader was detected. The same variable name was also conventionally used
when requiring it in Node.js or otherwise referring to it. This was
reflected in various places in the code, documentation, examples, etc.
This commit changes the variable name to "peg" and fixes all relevant
occurrences. The main reason for the change is that in Node.js, modules
are generally referred to by lower-case variable names, so "PEG" was
sticking out when used in Node.js projects.
Instead of setting ESLint environment to "node" globally, set it on
per-directory basis using separate .eslintrc.json files:
Directory Environment
-----------------------
bin node
lib commonjs
spec jasmine
It was impossible to use this approach for the "benchmark" directory
which contains a mix of files used in various environments. For
benchmark/run, the environment is set inline. For the other files, as
well as spec/helpers.js, the globals are declared manually (it is
impossible to express how these files are used just by a list of
environments).
Fixes#408.
Unit specs are unit tests of internal stuff. API specs are tests of the
user-visible APIs and behavior.
I think it makes sense to make this distinction because then the public
API line is more clearly visible e.g. when using the specs as
documentation.
Also added few missing |hasOwnProperty| calls that JSHint didn't detect
because it only looks whether there is an |if| statement wrapping the
loop body.
This is the first of many commits that gradually convert PEG.js's test
suite from QUnit to Jasmine, cleaning it up on the way.
Main reason for the change is that Jasmine allows nested contexts,
allowing to structure the tests in a better way than QUnit. Moreover,
the tests needed to be cleaned up a bit.
