way to get the file name except the extension

way to get the file name except the extension

[Kiwon Um]

Hello. I'm a newbie to elisp.

I'm wondering a built-in function or lisp codes to get the file name
except the extension from (buffer-name):
TestCode.cpp -> TestCode

Any advise? :)

easy.

you want file-name-sans-extension and file-name-nondirectory.

of langs i know that i've used extensively for processing file and dir
names, namely Python and Perl, none comes as easy to use as the funcs
provided in elisp.

you can get file dir name, file name, file suffix, strip suffix,
create dir including non existing parent dir, convert from full path
to relative path, etc, all built in in elisp with a simple function.

Thanks. It really works well. :
(file-name-sans-extension (buffer-name))

P.s. Is there any good reference point of the manual to manipulate the
time related strings, time, date, month, year, etc, like file name?

In "39 Operating System Interface" there are 3 sections that probably
contain something for you:

* Time of Day: Getting the current time. 
* Time Conversion: Converting a time from numeric form to calendrical data,
  and vice versa).
* Time Parsing: Converting a time from numeric form to text and vice versa.

Best regards.

Of course.

(file-name-sans-extension (buffer-name))

A quick way to discover commands is to type:

 C-h f <first-few-letters> TAB

 (C-h = Ctrl h)

so, to find out about file-* commands type:

 C-h f file TAB

and keep pressing TAB to cycle through the numerous results in the
pop-up window.

Add some more letters and type TAB again to narrow your search and when
you've found a command you're interested in type RET.

There's also 'M-x apropos'.
(M-x = Alt-x or ESC-x)

Type 'C-h f apropos RET' to learn about the 'apropos' command.
