deno_minimist's Issues

Capital letter short notation not working

with the input ['-T', 'ttt'] I expect the output {"T"; "ttt"} but I am getting {"_":["T", "ttt"]} in chrome.

Invalid parsing of muliple short arguments followed by assigment

The parser failes to handle the corner case where multiple short argument have an assigned at the end.

# broken behavior
$ deno run https://deno.land/x/[email protected]/examples/parse.ts -abc=def
{ _: [], a: "def" }

# multiple assignments really confuse the parser
$ deno run https://deno.land/x/[email protected]/examples/parse.ts -abc=d=e=f
{ _: [], a: "d" }

# the arguments separated out, gives the correct behavior.
$ deno run https://deno.land/x/[email protected]/examples/parse.ts -a -b -c=def
{ _: [], a: true, b: true, c: "def" }

#  even with the arguments separated out, the parser fails to account for multiple = characters.
$ deno run https://deno.land/x/[email protected]/examples/parse.ts -a -b -c=d=e=f
{ _: [], a: true, b: true, c: "d" }
$ deno run https://deno.land/x/[email protected]/examples/parse.ts -a -b -c==def
{ _: [], a: true, b: true, c: "" }

Single flag fails in chrome

When I parse -o and run the code in chrome I get a

params.js:403 Uncaught TypeError: arg.slice(...).split is not a function

from

const letters = arg.slice(1, -1).split("");
