Configuration

edit fm.awk, modify the first configuration section:

    ###################
    #  Configuration  #
    ###################

    OPENER = ( ENVIRON["FMAWK_OPENER"] == "" ? ( ENVIRON["OSTYPE"] ~ /darwin.*/ ? "open" : "xdg-open" ) : ENVIRON["FMAWK_OPENER"] )
    LASTPATH = ( ENVIRON["LASTPATH"] == "" ? ( ENVIRON["HOME"] "/.cache/lastpath" ) : ENVIRON["LASTPATH"] )
    HISTORY = ( ENVIRON["HISTORY"] == "" ? ( ENVIRON["HOME"] "/.cache/history" ) : ENVIRON["HISTORY"] )
    CMDHIST = ( ENVIRON["CMDHIST"] == "" ? ( ENVIRON["HOME"] "/.cache/cmdhist" ) : ENVIRON["CMDHIST"] )
    CACHE = ( ENVIRON["CACHE"] == "" ? ( ENVIRON["HOME"] "/.cache/imagecache" ) : ENVIRON["CACHE"] )
    FIFO_UEBERZUG = ENVIRON["FIFO_UEBERZUG"]
    FMAWK_PREVIEWER = ENVIRON["FMAWK_PREVIEWER"]
    PREVIEW = 0
    HIDDEN = 0
    RATIO = 0.35
    HIST_MAX = 5000
    SUBSEP = ","

OPENER is the default file opener. External opener script can be set by environmental variable FMAWK_OPENER.
LASTPATH is path which fm.awk were last time.
HISTORY is the history for directory visited.
CMDHIST is the command line history, which only the unique command will be left.
CACHE is the cache file path for image file generated by preview.
FIFO_UEBERZUG and FMAWK_PREVIEWER will be automatically set by shell wrapper fmawk.
PREVIEW is indicator for review or not, boolean.
RATIO is the ratio for directory / preview.
HIST_MAX is the maximum number of HISTORY.

cmd mode

all auto completed command can be edited using left/right arrow and backspace.
:cd /path/to/destination
- can be relative: :cd ../../ goes to parents two tiers
:cmd on each selected item.
- e.g., After selection, :chmod +x to give execution permission on selected entries.
:cmd {} destination to replace {} with each selected item and execute the whole command.
- e.g., After selection, :mv {} ~ will move selected item to $HOME directory.
File manipulation is done by this process:
- Select file/dir => go to destination by browsing => type :cmd {} ./ to execute cmd on selected file to destination
- e.g. select files, go to destination and type :mv {} ./.
cmd can be shell alias (bash and zsh confirmed. fish not sure).
tab completion on :cd and search (/)
tab completion on path:
- press tab or shift-tab for path completion => press Enter to confirm current completion, and go the either of the following two path:
  - => press tab / shift-tab for next-level path completion.
  - => press Enter again to confirm current path and exit cmd mode.
tab completion on command line mode based on command line history.
left / right arrow to move cursor; up / down arrow to access command line history.

`scripts`

scripts stores the shell scripts that serve some purposes that I think is better to be done externally. They are

decompressall: go through all compression files in current directory and decompress all of them.
renameall: rename all files and directories in current directory. The list of all files/directories will open in default text editor using xdg-open files/directories will be renamed line by line.

TODO

Image preview (start using ueberzug)
Make preview script be independent
Able to redraw by SIGWINCH.
Tab completion on path
Make cmd bottom line can be scrollable horizontally even when the string is over the dimension
Eliminate action menu by implementing all of those in cmd mode
