• Adds supported languages with aliases: supported_language_manifests method.
• Adds server_version method to check out bblfshd version being used.
• Adds default timeout of 60 seconds for parsing a file.
• Removes CLI. If you are seeking for a terminal CLI check out our go-client
• Solves a bug that crashed the python interpreter when decoding empty bytes: #189

Examples

import bblfsh

client = bblfsh.BblfshClient("localhost:9432")
# bblfshd version being used
client.server_version()
# supported languages with aliases
client.supported_language_manifests()

# Parse a file with no timeout
ctx = client.parse("file.py", mode=bblfsh.Modes.NATIVE, timeout = -1)
# Parse a file with 60 seconds timeout
ctx = client.parse("file.py", mode=bblfsh.Modes.NATIVE)
# Parse a file with 70 seconds tiemout
ctx = client.parse("file.py", mode=bblfsh.Modes.NATIVE, timeout = 70)

• Fixes memory leaks in ResultContext.filter method (native context was not getting deallocated after using the iterator)
• Bumps libuast version, which includes memory leak patches and a new iteration order: ChildrenOrder. Also ensures those iteration orders correspond to the ones present in libuast, lifting them from the native side.
• Adds managed context functionality:

# context owned by libuast
ctx = client.parse(filename)

# load to Python
ast = ctx.root.get()
# if we had a method to rename some nodes, for example
modified_dict = rename_variables(ast)

# context owned by Python
ctx = bblfsh.context(modified_dict)
... = ctx.filter("//uast:Identifier")

• Hotfix for the positional info getter.

• Node objects now expose the filter and iterate methods.
• CLI will no longer try to run bblfshd if a remote address is passed as an option.
• Added a root property to the response context (alias for uast and ast).
• Repository renamed to python-client for consistency.
• Fixes to v1 compatibility layer (thanks @zurk!).

There are no functional changes in this release. It removes the "3.4" and "3.5" Python version tags from the PyPI metadata to document the implicit fact that we require Python ≥ 3.6 (see #153).

• Update libuast to the latest version.

• Remove unnecessary requirement for GOPATH env when installing.

• First release using the new libuast in Go and the new XPath projection. The API also changed to reflect this and the client was completely rewritten.

• Added a compatibility layer with previous versions in the bblfsh.compat module. Note that XPath expressions probably need to be updated anyway since the projection changed.
