Re: Delete 1 line in file - Nubotron - 07.04.2009

Re: Delete 1 line in file - Nubotron - 07.04.2009

To remove a line by line number, you can use something like this (no it isn't Sacky's function, i have just writted it now! and work):

pawn Code:

fdeleteline(filename[], line)
{
  new count, string[256], File:file, File:temp;

  file= fopen(filename, io_read);
  temp = fopen("tmpfile.tmp", io_write);

  while (fread(file, string))
    if (++count != line)
      fwrite(temp, string);

  fclose(file);
  fclose(temp);

  file= fopen(filename, io_write);
  temp = fopen("tmpfile.tmp", io_read);

  while (fread(temp, string))
    fwrite(file, string);
    
  fclose(file);
  fclose(temp);
  fremove("tmpfile.tmp");
}

If your file is file.txt, and it contain this:

Code:

sd
afd
hgfgh
gfjg

if you do

pawn Code:

fdeleteline("file.txt", 3);

then file.txt will now contain

Code:

sd
afd
gfjg

Or read the entire file to a buffer, Use strreplace, Then write it back to the file

Re: Delete 1 line in file - Jefff - 07.04.2009

I have this

Code:

stock fdeleteline(filename[], dest[], remove[])
{
  new string[255], File:handle, File:ftmp;

  handle = fopen(filename, io_read);
  ftmp = fopen(dest, io_write);
  while(fread(handle, string)){
    for(new i = 0, j = strlen(string); i < j; i++) if(string[i] == '\n' || string[i] == '\r') string[i] = '\0';
 		if(strcmp(string, remove, false) != 0) fwrite(ftmp, string);
  }
  fclose(handle);
  fclose(ftmp);
  handle = fopen(filename, io_write);
  ftmp = fopen(dest, io_read);
  while(fread(ftmp, string)){
  for(new i = 0, j = strlen(string); i < j; i++) if(string[i] == '\n' || string[i] == '\r') string[i] = '\0';
	fwrite(handle, string);
	}
  fclose(handle);
  fclose(ftmp);
  fremove(dest);
}

but this write

Code:

sdf sffsfa dgsd dhfh dghfh

without spaces and I want that

Code:

sdf
sffsfa
dgsd
dhgfh
