Profiler

Profiler is a simple and lightweight ncurses file manager that is written in Haskell.
It uses vim-style keybindings and is modular.

Using Profiler

Upon launching Profiler, you will be put in Normal Mode.
The following keys are used for navigation in Normal Mode:

Key	Action
j,k	Move down/up
h	Move up a directory
l	If a directory is selected, navigate to that directory. Else execute the selected file.
H	Move to the file at the top of the page
L	Move to the file at the bottom of the page
o	Prompts for name of program to open the file with
g	Navigate to the first file in the directory
G	Navigate to the last file in the directory
d	Delete the selected file
y	Copy the selected file to a destination defined by an input prompt
S	Move the selected file to a destination defined by an input prompt
a	Create a directory (and its parents) defined by an input prompt
^	Navigate to the user's home directory
/	Search current directory
n	Next search result
N	Previous search result
Tab	Switch frames
q	Quit Profiler

Furthermore, the "j" and "k" inputs can be prepended with a number of files to go down/up by.
For example, typing "4j" in Normal mode will navigate 4 files downward.
Profiler is still in development. More keybindings and features are coming.

Configuration

Default Applications

Default applications can be specified in the ~/.profiler/defaults file, with the following syntax:

<file extension 1>, <program 1>
<file extension 2>, <program 2>
<file extension 3>, <program 3>
...

For example, the following is a valid ~/.profiler/defaults file:

pdf, evince
mp4, vlc
png, feh
doc, libreoffice
xlsx, libreoffice

Opening files with CLI/TUI programs, such as Vim, can be quite buggy when not done properly.
For such cases, it is recommended to open the file with your CLI/TUI program in another terminal emulator instance, as follows:
~/.profiler/defaults

hs, xterm -e vim

When trying to open a file type whose extension is not included in the ~/.profiler/defaults file, Profiler will fall back to xdg-open.

Custom Colorscheme

Custom color settings can be defined in the ~/.profiler/colors file, with the following syntax:

<color class1> <foreground1> <background1>
<color class2> <foreground2> <background2>

Foreground and background colors are 8-bit, so should be written as a number between 0 and 255, or -1 for the default terminal foreground or background.
Color class defines which part of the UI the following color pair should be used for.
Currently, the valid color classes are:

• selected: Color of the selected item
• folder: Color used for folders
• executable: Color used for executable files
• border: Color used for the border of the selected pane
• cwd: Color used for the output of the current working directory
• error: Color used for error messages
• symlink: Color used for a file that is a symbolic link Note that if a ~/.profiler/colors exists, it is recommended that all color classes be defined. Otherwise the colorscheme may look ugly. The default colorscheme would look like:

selected 4 -1
folder 4 -1
executable 83 -1
border 220 -1
cwd 220 -1
error 160 -1 
symlink 63 -1

Dependencies

Profiler depends on:

• ncurses
• The HSCurses library (# cabal install hscurses) (for building only)
• Data.List.Split installed in Gentoo via (# emerge dev-haskell/split) (for building only)
• Haskell's regex-base, installed in Gentoo via # emerge dev-haskell/regex-compat (for building only)
• The Glorious Glasgow Haskell Compiler (GHC) version 8.0.2 or newer (for building only)

Installing Profiler

To install Profiler, navigate to the directory of your choice and run the following commands:

$ git clone https://github.com/DestructiveReasoning/profiler.git
$ cd profiler
# make install

Profiler can then be launched: $ profiler.

Building Profiler

To build Profiler, ensure that you have the dependencies outlined above, and run the following in the directory of your choice:

$ git clone https://github.com/DestructiveReasoning/profiler.git
$ cd profiler
$ make
