Multi-line strings with keyword and pair arguments

[tkf]

I couldn't find the issue (maybe #501 is the closest) but I find this behavior strange

julia> code = """
       f(
       a = \"\"\"
       string
       \"\"\",
       b = \"\"\"
       string
       \"\"\",
       )
       """;

julia> print(code)
f(
a = """
string
""",
b = """
string
""",
)

julia> print(format_text(code))
f(a = """
  string
  """, b = """
       string
       """)

Similar with =>:

julia> code = """
       f(
       "a" => \"\"\"
       string
       \"\"\",
       "b" => \"\"\"
       string
       \"\"\",
       )
       """;

julia> print(code)
f(
"a" => """
string
""",
"b" => """
string
""",
)

julia> print(format_text(code))
f("a" => """
  string
  """, "b" => """
       string
       """)

I checked this with

(jl_XRYQ8s) pkg> st -m

hmmm so what's going on is it thinks the width of the code < the maximum width so it joins the lines which in this case ends up with a strange format.

If you just some 2 multiline strings (no binary op) then it doesn't do this right?

Yeah, I think this is expected:

julia> code = """
       f(
       \"\"\"
       string
       \"\"\",
       \"\"\"
       string
       \"\"\",
       )
       """;

julia> print(code)
f(
"""
string
""",
"""
string
""",
)

julia> print(format_text(code))
f(
    """
    string
    """,
    """
    string
    """,
)

My workaround ATM is to put some comments inside:

julia> code = """
       f(
       # workaround
       "a" => \"\"\"
       string
       \"\"\",
       "b" => \"\"\"
       string
       \"\"\",
       )
       """;

julia> print(code)
f(
# workaround
"a" => """
string
""",
"b" => """
string
""",
)

julia> print(format_text(code))
f(
    # workaround
    "a" => """
    string
    """,
    "b" => """
    string
    """,
)
