Hello guys, recently found Nim and very much interested in this language. I have written a program which use imghdr at https://github.com/achesak/nim-imghdr
But I can't compile the program. Can you guys tell me what I am doing wrong?
My code:
import os, imghdr, osproc
proc imagecheck(path:string) =
var f: File
var extensions = [".jpg", ".png", ".bmp", ".gif"]
if open(f, "falseimglist", fmReadWrite):
for fname in walkDirRec(path):
var extension = splitFile(fname)[2]
var imagetype = testImage(fname)
if extension in extensions:
if $imagetype == "Other":
f.write("This is not an image: ",fname)
close(f)
proc test_bmp(strng: string,filename: File, line: string) =
if find(strng, "BMP") == -1:
filename.write("This is not an image: " & line &"\n")
proc test_gif(strng: string, filename:File, line: string) =
if find(strng, "GIF") == -1:
test_bmp(strng, filename, line)
proc test_png(strng:string, filename:File, line: string) =
if find(strng, "PNG") == -1:
test_gif(strng, filename, line)
proc test_image_file(strng:string, filename:File, line:string) =
if find(strng, "JPEG") == -1:
test_png(strng, filename, line)
proc main(path:string) =
imagecheck(path)
var
command: string
output: string
f: File
f2: File
if open(f, "falseimglist", fmReadWrite):
if open(f2, "falseimglist2", fmReadWrite):
for line in f.lines:
var line2 = replace(line, "\n", "")
command = "file " & line2
var output_tuple = execCmdEx(command)
output = output_tuple[0]
test_image_file(output, f2, line2)
f.close()
f2.close()
removeFile("falseimglist")
var path = commandLineParams()[0]
main(path)The error when compiling is
