Support julia

[jolars]

It would be nice to support julia. We could probably borrow a lot from for instance the R and python parsers.

In order to add a new language, I need sample code with oneline/multiline nodes for that language (example: https://github.com/Wansmer/treesj/tree/main/tests/sample).

I hope this is something along the lines of what you wanted. I am not 100% sure if I got it right, for instance I just put preset default everywhere, but I don't really know what that does :). I also wasn't sure if the nested array needed special handling or not

# RESULT OF JOIN (node "argument_list", preset default)
filled_dict = Dict("one" => 1, "two" => 2, "three" => 3)
# RESULT OF SPLIT (node "argument_list", preset default)
filled_dict = Dict(
  "one" => 1,
  "two" => 2,
  "three" => 3,
)

# RESULT OF JOIN (node "vector_expression", preset default)
other_arr = [4, 5, 6]
# RESULT OF SPLIT (node "vector_expression", preset default)
other_arr = [
  4,
  5,
  6,
]

# RESULT OF JOIN (node "matrix_expression", preset default)
other_arr = [1 2 3; 4 5 6]
# RESULT OF SPLIT (node "matrix_expression", preset default)
other_arr = [
  1 2 3
  4 5 6
]

# RESULT OF JOIN (node "vector_expression", preset default)
other_arr = [[1 2 3], [4 5 6]]
# RESULT OF SPLIT (node "vector_expression", preset default)
other_arr = [
  [1 2 3],
  [4 5 6],
]

# RESULT OF JOIN (node "vector_expression", preset default)
multi_arr = [[1, 2], [3, 4], [5, 6]]
# RESULT OF SPLIT (node "vector_expression", preset default)
multi_arr = [
  [1, 2],
  [3, 4],
  [5, 6],
]

# RESULT OF JOIN (node "tuple_expression", preset default)
tup = (1, 2, 3)
# RESULT OF SPLIT (node "tuple_expression", preset default)
tup = (
  1,
  2,
  3,
)

# RESULT OF JOIN (node "argument_list" and "function_definition", preset default)
function create_adder(x, b)
  adder(y) = x + y
  return adder
end

# RESULT OF SPLIT (node "argument_list" and "function_definition", preset default)
function create_adder(
  x,
  b,
)
  adder(y) = x + y
  return adder
end

# RESULT OF JOIN (node "comprehension_expression", preset default)
comp_arr = [i^2 for i in 1:5]
# RESULT OF SPLIT (node "comprehension_expression", preset default)
comp_arr = [
  i^2
  for i in 1:5
]

# RESULT OF JOIN (node "call_expression", preset default)
result = sum([1, 2, 3])
# RESULT OF SPLIT (node "call_expression", preset default)
result = sum(
  [1, 2, 3]
)

# RESULT OF JOIN (node "using_statement", preset default)
using Statistics, Lasso, ProjectRoot
# RESULT OF SPLIT (node "using_statement", preset default)
using Statistics,
  Lasso,
  ProjectRoot

# RESULT OF JOIN (node "selected_import" and "using_statement", preset default)
using Statistics: mean, median, std
# RESULT OF SPLIT (node "selected_import" and "using_statement", preset default)
using Statistics:
  mean,
  median,
  std

# RESULT OF JOIN (node "open_tuple" and "assignment", preset default)
t1, t2, t3 = (1, 2, 3)
# RESULT OF SPLIT (node "tuple_expression" and "assignment", preset default)
(
  t1,
  t2,
  t3,
) = (1, 2, 3)

Great! Thanks a lot for the work on this!
