⚠️ Howto to upgrade to grewpy 0.5

In release 0.5, the implementation of the Request class has been updated.

The two changes that require code updates are described below.

1) Deprecated function Request.parse

The Request.parse function is now deprecated. It still works in the version 0.5, with a deprecated message. It will be removed in a future release.

With the new version, the same argument (following the syntax used in Grew-match or in the request part of rules in Grew) can be used directly to build the corresponding request.

The table below describes the main changes required to existing code:

Version < 0.5.0	Version ≥ 0.5.0
Request.parse ("pattern { X -> Y } without { X[upos=VERB] }")	Request("pattern { X -> Y } without { X[upos=VERB] }")

2) Build a request from a string

As a consequence of the previous point, the previous way of building a request from a clause or a clause list is no longer available. The easier way to patch the code is to start with an empty request with Request() and to append clauses with the pattern method.

The table below describes the main changes required to existing code:

Version < 0.5.0	Version ≥ 0.5.0
Request ("X -[subj]-> Y", "X[upos=VERB]")	Request().pattern("X -[subj]-> Y", "X[upos=VERB]")
