file_path_name_ext(-File:atom, -DExt:atom, ?Path:atom, +Name:atom, +Extension:atom) is multi

Separate a (full) URL into Path, Name and Extension, or construct the absolute file name from Path (optional), Name and Extension (or DExt).

Note: In alignment with URI formats, filenames may end with #, typically in cases where the filename is used as a prefix for entities. In this case, the # is stripped from the name and ignored.

Arguments:

File	- If input, then an "expandable" file path and name. Extension is optional, if a default extension DExt is given. Input may optionally have a scheme prefix of `file://`. Input may also have an ending URI entity suffix (#) which will be stripped. If output, then the absolute file path and name.
Path	- If input, then an "expandable" path. Trailing slashes are optional for resulting absolute file names. If output, then absolute path, including trailing slash.
Name	- Filename without extension
DExt	- Default filename extension (e.g. txt) without the dot prefix
Extension	- Filename extension (e.g. txt) without the dot prefix Example use: :- file_path_name_ext('~/.config/swi-prolog/init.pl',P,N,E). P = '/home/myusername/.config/swi-prolog/'' N = init E = pl :- file_path_name_ext(F,library(pldoc),doc_process,pl). F = '/home/myusername/.config/swi-prolog/library/pldoc/doc_process.pl'; F = '/usr/lib/swi-prolog/library/pldoc/doc_process.pl'; ...etc.

 lastchar(+Text:atomic, ?Char:char) is semidet

Get or check the last character of a string or atom

Arguments:

Char	- the last character of Text Example use: :- lastchar('Hello World!',C). C = '!'

 firstchar(+Text:atomic, ?Char:char) is semidet

Get or check the first character of a string or atom

Arguments:

String	- string or atom
Char	- the first character of Text Example use: :- fistchar('Hello World!',C). C = 'H'
