Replacing grep, sed, awk scripts with Julia

General Usage
10

In fact the problem was because $ need to be escaped with \ when using in command line.

WIP:

jsed.jl

code = join(ARGS, ";")
template = """
for (count, line) in enumerate(readlines(stdin))
    $(code)
end
"""
eval(Meta.parse(template))

Usage:

cat data.txt | julia jsed.jl """
line = uppercase(line)
cur_name, cur_symb, _, value = split(line)
cur_symb = strip(cur_symb, ['(', ')'])
println(\"\$(count) \$(lpad(cur_name, 10)) \$(lpad(value, 3)) \$(cur_symb)\")
"""

or as one-liner

cat data.txt | julia jsed.jl "line = uppercase(line)" "cur_name, cur_symb, _, value = split(line)" "cur_symb = strip(cur_symb, ['(', ')'])" "println(\"\$(count) \$(lpad(cur_name, 10)) \$(lpad(value, 3)) \$(cur_symb)\")"

or

cat data.txt | julia jsed.jl "line = uppercase(line); cur_name, cur_symb, _, value = split(line); cur_symb = strip(cur_symb, ['(', ')']); println(\"\$(count) \$(lpad(cur_name, 10)) \$(lpad(value, 3)) \$(cur_symb)\")"

but jsed need now to be more “generic”, accepting several kind of templates.

We also need to have jsed as a system command (ie available in path) so we could do:

cat data.txt | jsed "line = uppercase(line)" "cur_name, cur_symb, _, value = split(line)" "cur_symb = strip(cur_symb, ['(', ')'])" "println(\"\$(count) \$(lpad(cur_name, 10)) \$(lpad(value, 3)) \$(cur_symb)\")"
