Following changes have been made:
1. Moving the getMusicDirectory() to config package
2. Moving the config.go to config package
3. Generating a Function Map that will be used for Generating keymappings in main.go
4. Using the config packge in main.go
5. First we are reading the user configuration values with
config.ReadConfig() and then we are reading the mappings with
config.ReadMappings() with the help of Function Map that is
generated.
Image is now resized according to the font size and also a new
globals.go files is added which contains all the globals.
the Image width can also be changed according to use by adding or
substracting pixels to it by changing the globals
IMAGE_WIDTH_EXTRA_X, IMAGE_WIDTH_EXTRA_Y
Also, now there is no need to specify where the music directory is
the mpd.conf file in `~/.config/mpd/` is automatically parsed for music
directory
the position is now calculated with the help of font_pixel_width and
font_pixel_height
font_pixel_width = Total X Pixels / Total Columns
font_pixel_height = Total Y Pixels / Total Rows
which is then multiplied to row and column co-ordinates of preview box to get it's
pixel position.
The ProgressBar is just a string which has a length equal to the
innerRect of the table. The length of the innerRect is considered to be
100% and the rest of the progress is tracked in relation to it.
The Progress is displayed with the help of the color formatting strings
in tview
link: https://pkg.go.dev/github.com/rivo/tview#hdr-Colors
the progress length which is calculated by finding the percentage of the
innerRect that matches with the given completion and then at that length
the "[-:-:-]" is inserted with the help of the insertAt function in
utils.go. "[-:-:-]" represents resetting of colors.
