[SOLVED] Most library minimal Norton Command like applications?

Xeratul · 05-05-2017, 02:25 PM

Hello,

I am looking for a very portable, tiny, Norton Command like applications (opensource). I am just beginning C coding.

Of course, it is nice to have a file browser under the terminal/console.

Sometimes, there isn't ncurses devel, nor libtinfo.so.5, on the BSD/Linux/Solaris/... system. It may be useful, comfortable, to have an alternative the Midnight Commander, based on C, which could be easily compiled. Don't you think?

thank you.

work in progress. I will bring it on the tiniest, library really freeeee, as ever ... so that it can work even on a 1950's toaster

I, for one, am REALLY looking forward to this.

For years (decades...

) mc has been my go-to tool for CLI file management... And I'm utterly disappointed that it is not stand-alone and that it is quite bulky for an application of it's type, and has too many dependencies.

This looks very promising, Xeratul. Colour me impressed.

Please keep up the good work!

P.S. It didn't compile for me under Slackware 14.2:

I think that some libraries could be added before.

Code:

#include <stdlib.h>
#include <stdio.h>
#include <string.h>
#include <dirent.h> //
// for fexist
#include <ctype.h>
#include <sys/stat.h>
#include <dirent.h>
#include <sys/types.h>
#include <unistd.h>
// time 
#include <time.h>
#include <ncurses.h>

and fexist.

while compiling, you may add ncurses :

Code:

gcc name-of-source-file.c -o output-programme -lm -lncurses

with before:

Code:

apt-get install ncurses5-dev

here "-dev" means devel for compiling.

I'm doing this on Slackware, which includes the dynamic libraries in every package.

Does mnc need the static library?

it does not need libs, just ncurses-dev

strrlf is to remove the LF. You can just remove it into the src code if you want to make the code work'.

Xeratul · 05-28-2017, 08:43 AM

If it worked out, well, you may eventually make a GIT HUB project or branch, to allow other users to compile it on slackware box.

If you'd like...

rkelsen · 05-29-2017, 05:16 AM

It compiled without needing anything extra, apart from the tweaks above.

I'd be happy to contribute wherever I can.

you can make a project or fork of this tiny browser. it can greatly help people who have hands on a ssh, and that have nothing installed. This tiny broweser is great when no single libraries are installed, just gcc and fews.
this app is of great help when you have on a distant ssh new server.

Hi,

I am happy to give you the NIGHT COMMANDER. It is a all-mighty file manager.
https://github.com/spartrekus/nc

Let me know your impressions.
:Have Fun:

fatmac · 06-05-2017, 08:59 AM

Interesting project, looks like a cross between mc & vifm.

I used to have mc-light on one of my distros a while ago, but they stopped development of it.
File manager & editor combined with a compressed file extracter, basically, from memory.

you can use "nc", it is much better

You can test it...
It's free (=0$$).
