* Split a Filename Code Snippet

[tatewise]

The plugins:code_snippets:split_filename_in_to_path_filename_and_extension|> Split a Filename into Path, File, and Extension (code snippet) exhibits an interesting effect with an FH Project folder such as ...\FH Projects\xyz\xyz.fh_data.

It returns the following three values:
...\FH Projects\xyz\
xyz.fh_data
fh_data
which is somewhat misleading as xyz.fh_data is a folder and NOT a file, and fh_data is NOT a file type.

If a folder such as ...\FH Projects\xyz is used it returns three nil values.

The following alternative function works rather better:

Code: Select all

-- Return the Path, Filename, and extension as 3 values
function SplitFilename(strFilename)
	if lfs.attributes(strFilename,"mode") == "file" then
		return strFilename:match("(.-)([^\\]-([^\\%.]+))$")
	end
	local strPath = strFilename:gsub("[\\/]$","")
	return strPath.."\\","",""
end -- function SplitFilename

In the above cases it returns the values:
...\FH Projects\xyz\xyz.fh_data\ or ...\FH Projects\xyz\
plus two empty strings.

Good idea Mike, I would be tempted to put both the in the snippets, as the original one is the one found on many other Lua sites.

I have updated plugins:code_snippets:split_filename_in_to_path_filename_and_extension|> Split a Filename into Path, File, and Extension (code snippet) as suggested.
