tree-sitter

curl -k --digest --user username:password url

is converted to

import requests
response = requests.get('http://url', verify=False, auth=('username', 'password'))

but should be

import requests
response = requests.get('http://url', verify=False, auth=requests.auth.HTTPDigestAuth('username', 'password'))

With the increasing number of parsers (and more coming), CI is starting to take a while...

We should pare down the number of tests:

1. reduce the combinations of platform, compiler, and Neovim version;
2. only run one combination (Ubuntu, gcc, nightly? that seems to be the fastest) on draft PRs (and push people to keep the PRs as draft until actually ready for review);

~3. avoid running

Tree-sitter states that it has "fairly complete" support for 34 languages with 12 more in development.

Right now this project states its support for 11 languages. Is there a way we can increase this number?

Either add on to existing queries or add support for new languages. Relevant queries can be found using playground. See existing queries for examples (Rust is a good example).

(Elisp)-tree-sitter represents sections of the code it cannot parse as ERRORsymbol tokens. Currently the parser will fail as if a transformation is invalid if any ERROR tokens are present. Instead, we should check if the tokens in an operation contain ERROR, and alert the user that their code is malformed if so.
