class FileScan [deprecated] ¶

This module is deprecated because it doesn't support file globbing or regexes for matching files and because it ignores folders that it doesn't recurse into (a non-recursive scan will never return any folders).

Recursively scan files and directories, adding filtered files to an output structure as we go. This can be used to produce a list of subdirectories and the files contained therein. The following example lists all files with suffix ".d" located via the current directory, along with the folders containing them:

auto scan = new FileScan; scan (".", ".d"); Stdout.formatln ("{} Folders", scan.folders.length); foreach (folder; scan.folders) Stdout.formatln ("{}", folder); Stdout.formatln ("\n{} Files", scan.files.length); foreach (file; scan.files) Stdout.formatln ("{}", file);

This is unlikely the most efficient method to scan a vast number of files, but operates in a convenient manner.

alias FilePath.Filter Filter ¶

Alias for Filter delegate. Accepts a FilePath & a bool as arguments and returns a bool.

The FilePath argument represents a file found by the scan, and the bool whether the FilePath represents a folder.

The filter should return true, if matched by the filter. Note that returning false where the path is a folder will result in all files contained being ignored. To always recurse folders, do something like this:

return (isDir || match (fp.name));

const(char)[][] errors() [public] ¶

Return all the errors found in the last scan

FilePath[] files() [public] ¶

Return all the files found in the last scan

FilePath[] folders() [public] ¶

Return all directories found in the last scan

FileScan sweep(const(char)[] path, bool recurse = true) ¶

Sweep a set of files and directories from the given parent path, with no filtering applied

FileScan sweep(const(char)[] path, const(char)[] match, bool recurse = true) ¶

Sweep a set of files and directories from the given parent path, where the files are filtered by the given suffix

FileScan sweep(const(char)[] path, Filter filter, bool recurse = true) ¶

Sweep a set of files and directories from the given parent path, where the files are filtered by the provided delegate
