From 1a830a3d1b9d99653322d5ae49ea8165de7ed9d0 Mon Sep 17 00:00:00 2001 From: Ben Bridle Date: Mon, 28 Oct 2024 20:25:01 +1300 Subject: Rewrite emulator This is a complete rewrite and restructure of the entire emulator project, as part of the effort in locking down the Bedrock specification and in creating much better tooling for creating and using Bedrock programs. This commit adds a command-line argument scheme, an embedded assembler, a headless emulator for use in non-graphical environments, deferred window creation for programs that do not access the screen device, and new versions of phosphor and bedrock-core. The new version of phosphor supports multi-window programs, which will make it possible to implement program forking in the system device later on, and the new version of bedrock-core implements the final core specification. --- src/devices/file/operations.rs | 47 ------------------------------------------ 1 file changed, 47 deletions(-) delete mode 100644 src/devices/file/operations.rs (limited to 'src/devices/file/operations.rs') diff --git a/src/devices/file/operations.rs b/src/devices/file/operations.rs deleted file mode 100644 index 0593ac8..0000000 --- a/src/devices/file/operations.rs +++ /dev/null @@ -1,47 +0,0 @@ -use std::io::ErrorKind; -use std::path::Path; - - -/// Returns true if an entry already exists at the given path. -pub fn entry_exists(source: &Path) -> bool { - std::fs::metadata(source).is_ok() -} - -/// Delete an entry, returning true if successful. -pub fn delete_entry(source: &Path) -> bool { - match std::fs::remove_file(source) { - Ok(_) => true, - Err(e) => match e.kind() { - ErrorKind::NotFound => true, - ErrorKind::IsADirectory => match std::fs::remove_dir_all(source) { - Ok(_) => true, - Err(e) => match e.kind() { - ErrorKind::NotFound => true, - _ => false, - } - } - _ => false, - } - } -} - -/// Move an entry from one location to another, returning true if successful. -pub fn move_entry(source: &Path, destination: &Path) -> bool { - if !entry_exists(source) || entry_exists(destination) { - return false; - } - std::fs::rename(source, destination).is_ok() -} - -/// Create a new file if it doesn't already exist, returning true if successful. -pub fn create_file(destination: &Path) -> bool { - if entry_exists(destination) { - false - } else { - if let Some(parent_path) = destination.parent() { - let _ = std::fs::create_dir_all(parent_path); - } - std::fs::OpenOptions::new().write(true).create_new(true) - .open(destination).is_ok() - } -} -- cgit v1.2.3-70-g09d2
