mirc/commands/fopen
The /fopen command opens <filename> and assigns it a handle. The file is opened for both writing and reading: see file handling. If an error occurred, processing does not halt. You must check that $fopen(<handle>).err or $ferr is not true.
Contents
Synopsis
/fopen [-no] <handle> <filename>
Switches
- -n - Create a new file, fails if already exists
- -o - Creates a new file, overriding an old one if exists
- -x - Opens the file in exclusive mode (will fail to open if already in use)
Parameters
- <handle> - A handle associated with an open file.
- <filename> - The filename to open.
Example
A simple example that prints one line to a new file:
; simple fopen example alias fopen_example { .fopen -n h hello.txt ;error check if ($ferr) { echo -sce info * /fopen_example: example.txt already exists! halt } ;print text .fwrite h Hello There ;close the handle .fclose h ;open file in default editor run hello.txt }
A script that prints all the permutations of there-characters to a file.
; print permutations [aaa]-[zzz] alias perm_example { .fopen -n h example.txt ;error check if ($ferr) { echo -sce info * /fopen_example: example.txt already exists! halt } ;print all the permutations to the file var %x = 97 while (%x < 123) { var %y = 97 while (%y < 123) { var %z = 97 while (%z < 123) { .fwrite -n h $+($chr(%x), $chr(%y), $chr(%z)) inc %z } inc %y } inc %x } ;close the handle .fclose h }
Broken Compatibility
in mIRC 7.22 /fopen left the handle open even after it failed. The compatibility change stated above was changed back to the old behavior in mIRC 7.24.
