A line-editor with a pop-up menu for easely inserting special APL characters. It is able to interact with GNU APL.
##Installation
Compile it with:
gcc -Wall -fPIC -shared -o apledit.so apledit.c -ldl
##Usage
The program has to be run through the LD_PRELOAD mechanism.
LD_PRELOAD=./apledit.so apl --noCIN
Of course, once you have found a good location for the binary file, you should create some alias for your shell in order to type only apl or some easy to remember command.
You can enter the editor whenever you want with the apledit-mode function.
##Settings
The key bindings must be set in the ~/.inputrc configuration file of each user. Example:
$if APLedit
"\e[2~": apledit-mode # key "insert"
"\e[5~": apledit-category-up # key "page up"
"\e[6~": apledit-category-down # key "page down"
#"\e[5~": apledit-item-up # key "page up"
"\e[3~": apledit-item-down # key "suppr"
"\e/": apledit-insert-char # key "menu" (below, next to right-ctrl)
$endif
If for some reason another file is wanted, its path has to be stored in the APLEDIT_INITFILE environment variable.
You can customize the menu with something like:
export APLEDIT_PROMPT='%s [%s] '
export APLEDIT_COLOR=$'\033[0;1m'
You can change the color of the banner (concerning APLedit) with:
export APLEDIT_COLOR_BANNER=$'\033[0;35m'
You can display the key to be typed for displaying the menu as a remainder:
export APLEDIT_BANNER_KEY="true"
You can also remove the whole banner with:
export APLEDIT_NOBANNER="true"
