Handle macos SDK in the justfile include_args

[mkatychev]

just lint would return missing header errors for macOS making debugging tricky:

checking file src/scanner.c
5 warnings and 1 error generated.
Error while processing /Users/mkatychev/Documents/tree-sitter/just/src/scanner.c.
./tree_sitter/parser.h:10:10: error: 'stdlib.h' file not found [clang-diagnostic-error]
#include <stdlib.h>
         ^~~~~~~~~~

Added conditional to include_args for handling CPATH to stdlib.h:

tree-sitter-just/justfile

Lines 20 to 24 in 59f661c

	include_args := "-Isrc/ -I" + ts_path + "/lib/include -Inode_modules/nan" + if os() == "macos" {
	" -I" + `xcrun --sdk macosx --show-sdk-path` + "/usr/include/"
	} else {
	""
	}

dependency checker now own just command:

tree-sitter-just/justfile

Lines 57 to 75 in 59f661c

	_check_installed +dep:
	#!/bin/sh
	set -eau
	check_installed() {
	printf "checking $1... "
	local dep=0
	command -v "$1" 1>/dev/null || dep=$?
	if [[ "${dep}" == 0 ]]; then
	echo "tool $1 found!"
	else
	echo
	echo "tool $1 NOT found. This may be needed for some functionality"
	fi
	}
	for d in {{dep}}; do
	check_installed $d
	done

Added justfile to .editorconfig:

tree-sitter-just/.editorconfig

Lines 41 to 43 in 59f661c

	[justfile]
	indent_style = tab
	indent_size = 4

this allows checking dependencies that do not have a --version flag

Thanks! One nit then lgtm

Nit, double whitespace

[tgross35]

Looks good, thanks for the changes!

[mkatychev]

@tgross35 I'm surprised this kk passed CI, I wonder if the check was skipped?

[tgross35]

check-installed doesn't actually require it be installed, just warn when it isn't. Maybe this should change on CI.

I actually had to adjust this in #186 and removed it there - it was always saying not found, bash syntax with a sh shebang :) I should have read the output better

I should have tested it myself, should not have pushed the commit
