kandi X-RAY | pine Summary
This is the repository for Pine, a really simple ML-like language powered by Rust and LLVM. It aims to be simple enough that a compiler can be written in a reasonably small amount of code, yet powerful enough to do high-level programming tasks and, in particular, sophisticated abstractions. Pine's type system is heavily inspired by the Hindley-Milner type system for the lambda calculus. Parameteric polymorhism and type inference are major features of Pine's type system. In fact, one does not specify types for parameters to functions in Pine - the types are inferred based on their usage within the function. Pine compiles to native code and links against a minimal runtime. To accomplish this, the Pine compiler has a monomorphization pass where generic functions are instantiated with concrete types and turned into unique functions, specialized to the instantiated types.

QUESTION
I would like to loop through the "FRUIT" column in the dataframe below and output a boolean value in another column,called "STATUS" based on the ordering of the values in the "FRUIT" column. Whenever the string "PINE" is positioned before the word "ORANGE" in the list I need the value in the STATUS column to be "TRUE" otherwise the value would be "FALSE"
I tried the code below but did not get the expected result:
...ANSWER
Answered 2022-Apr-09 at 13:30One possibility would be to use regular expressions. Note that this also will return True if somethings else is between PINE and ORANGE. Depending on what you want exactly, you can adjust the regular expression.

My target: create a Phonetic Keyboard in the Tamil language, using dictionary key mapping. My struggle: How to replace my keys with values and set that value to my textbox. For Example: If I press "K" in textbox1, then my textbox1.text will change into the Tamil letter "க்", if I press "Ku" then textbox1.text will be replaced by the Tamil letter "கு",, if I press "kuu" then textbox1.text will be replaced by the Tamil letter "கூ" And then If I press "m" then the Tamil letter "ம்" will be added to the previous letter "கூ" and now textbox1.text becomes "கூம்"

...I try to make all the trees after sorting to lowercase but For some reason, I cannot make the lower case to the listTree() work! I know that to lowercase() need to be pasted in a function in order for it to work with the array. But I am not sure how to add to the listTrees() function. Do we need to use if-else statement?
ANSWER
Answered 2022-Mar-10 at 08:43toLowerCase() is only used with strings here you are using toLowerCase() with array. If you want all array items to be in lowercase you need to transform each array items like that:

I'm getting this error in pine script could someone help me to solve this code please Here is my code
Cannot call 'ta.rsi' with argument 'length'='lowers'. An argument of 'series float' type was used but a 'simple int' is expected
...ANSWER
Answered 2022-Mar-04 at 08:47Replace mfi = ta.rsi(uppers, lowers) with mfi = 100.0 - (100.0 / (1.0 + uppers / lowers)) to get the calculation that you intend to; ta.rsi() can no longer be used to calculate mfi like that. You can read more about this behavior in the migration guide.

QUESTION
I am writing a pine script code to plot some lines conditionally. I see pine script v5, plot() function has display argument, still I am getting an weird error. Any idea what it could be?
Code:
...ANSWER
Answered 2022-Feb-12 at 08:09You should apply your condition to the series argument of plot(). The display argument is whether to enable or disable the plot by default and I believe it must be a constant.
And you probably want to change the style to something like plot.style_circles so your line won't be connected.
QUESTION
I tried to convert pine v2 iff function to v5 but I kept getting this error:
...ANSWER
Answered 2022-Feb-08 at 06:20Your conversion is correct, however, there is one more change you need to know when upgrading from v2. That is, you cannot use any variable in calculations while you are declaring that variable. So, you need to declare it first then give it a new value.

I am wanting to create a bar chart of top 5 populated states. My current function does not work for three reasons. 1) The most populated states are California,Texas,Florida,New York, and Pennsylvania. 2) The largest state the graph shows, california is the last one on the graph when it should be the first. 3) the y axis values are completely wrong.
