it is a stack based programming language. very like assembly themed. only integers are allowed as parameters, so to build "strings" is very annoying. it isn't meant for actual use. it was more for a project. i wouldnt even consider it an esoteric language because it has 0 creativity.
first, navigate to the directory where you have index.py saved. then run this command: python3 index.py <NAME OF THE FILE YOU WANT TO RUN IN LUX HERE>
note that the documentation is not consistent with the language - by this I mean when a new command is added, it may take a while for it to be documented. also, if you are having trouble outputting text, look to this website https://r12a.github.io/app-conversion/ , type in your string, then look down to the "decimal" section. those are the values you must push to get the message. you can include comments using the rem command, although using the # character is better. Here is an example: #this wont run!!!# psh 10
0 means it ended normally. 1 means it includes warnings. 2 means it includes fatal errors. 3 means the program ended it with end.
push a value (p0) onto the stack
pop top value of the stack
pops the top value of the stack then pushes it twice
pops the top value of the stack then turns it to unicode and appends it to the textbuffer
outputs values of the textbuffer onto the screen
outputs values in the stack (turned into unicode) from first index to last until it reaches a zero.
pops 2 top values of stack, adds them, and pushes result
pops 2 values from top of stack, then does Topmost value - Other value and pushes result
pops 2 values from top of stack, then multiples and pushes result
pops 2 values from top of stack, then does Topmost value / Other value and pushes result
jumps to the command index specified (p0) which starts from 0 being the first note rem counts as a command
jumps to the command index specified (p0) which starts from 0 being the first only if top two values of stack are equal doesn't pop the top two note rem counts as a command
jumps to the command index specified (p0) which starts from 0 being the first only if the top value popped is less than the second value popped doesen't pop the values, re-pushes them note rem counts as a command
jumps to the command index specified (p0) which starts from 0 being the first only if the top value popped is less than or equal to the second value popped doesn't pop the values, re-pushes them note rem counts as a command
a comment. can only contain numbers in it tho
outputs the contents of the raw stack without turning into unicode
outputs the [lux/log]: dummy. useful for debug
reverses the stack, making the top value the bottom one, etc
ends the program
