Mojo module
file
Provides APIs to read and write files.
These are Mojo built-ins, so you don't need to import them.
For example, here's how to read a file:
var f = open("my_file.txt", "r")
print(f.read())
f.close()Or use a with statement to close the file automatically:
with open("my_file.txt", "r") as f:
print(f.read())comptime values
O_APPEND
comptime O_APPEND = platform_map[Optional[String]("O_APPEND"), linux=Optional[Int](1024), macos=Optional[Int](8)]()
Append mode: writes always go to end of file.
O_CLOEXEC
comptime O_CLOEXEC = platform_map[Optional[String]("O_CLOEXEC"), linux=Optional[Int](524288), macos=Optional[Int](16777216)]()
Close file descriptor on exec.
O_CREAT
comptime O_CREAT = platform_map[Optional[String]("O_CREAT"), linux=Optional[Int](64), macos=Optional[Int](512)]()
Create file if it doesn't exist.
O_RDONLY
comptime O_RDONLY = 0
Open file for reading only.
O_RDWR
comptime O_RDWR = 2
Open file for reading and writing.
O_TRUNC
comptime O_TRUNC = platform_map[Optional[String]("O_TRUNC"), linux=Optional[Int](512), macos=Optional[Int](1024)]()
Truncate file to zero length.
O_WRONLY
comptime O_WRONLY = 1
Open file for writing only.
Structs
