parse-listing 
Simple library that parses file listing input for different platforms. An
example file listing is the output of the ls command in unix, or the dir
command in DOS/Windows platforms.
Example
var Parser = require("parse-listing");
// Yeah yeah, multiline strings would make Crockford mad, I know.
var str = "drwxr-xr-x 5 1001 1001 4096 Jan 09 11:52 .\r\n\
drwxr-xr-x 4 0 0 4096 Sep 19 13:50 ..\r\n\
-rw------- 1 1001 1001 1118 Jan 09 12:09 .bash_history\r\n\
-rw------- 1 1001 1001 943 Jan 09 11:52 .viminfo\r\n\
drwxrwxr-x 5 1001 1001 4096 Jan 09 11:52 inaccessible\r\n\
drwxrwxrwx 2 1001 1001 4096 Sep 21 11:20 project1\r\n\
drwx------ 2 1001 1001 4096 Oct 19 16:17 project2\r\n";
Parser.parseEntries(str, function(err, entryArray) {
entryArray.forEach(function(entry, i) {
console.log("Name:",entry.name);
console.log("Type", entry.type);
console.log("Size:", entry.size);
});
});
The example above will print the name, type and size for every entry in the listing. A parsed line becomes a JavaScript object like this:
{
type: 1,
size: 4096,
name: "project2",
time: 1382192220000,
owner: "1001",
group: "1001",
userPermissions: {
read: true,
write: true,
exec: true
},
groupPermissions: {
read: false,
write: false,
exec: false
},
otherPermissions: {
read: false,
write: false,
exec: false
}
}
Methods
parseEntries(string | array, callback)
Asynchronously parses a list of entries either in a single string (entries will be split by newlines) or in an array of strings. Invokes the callback when all the entries have been processed, and passes an array of JavaScript objects.
parseEntry(string)
Parses a single string such as:
drwxrwxrwx 2 1001 1001 4096 Sep 21 11:20 project
and returns the JavaScript object for it. There is no need to specify whether the entry is in UNIX or MS-DOS/Windows format. The parser will find out by itself.
