Kaleidoscope is a small library which provides pattern matching using regular expressions, and extraction of capturing groups into values. In particular, patterns are written inline, and do not need to be predefined.

QUESTION
I was following the Kaleidoscope tutorial making my own language with an if-else expression. I want to create to 2 blocks if
and else
that the function branches to depending on a condition. Both blocks then branch back to a merge
block where I have a phi node that gets the value from the correct block. However, I keep getting weird error when calling the function PHINode::addIncoming
, am I using the function wrong? Or is there something I'm missing?
I created a fairly small example:
...ANSWER
Answered 2022-Jan-04 at 20:35So, the project in visual studio was not setup correctly. I recommend reading this article for how to setup visual studio correctly with llvm. Then, I looked in the official vs project for the kaleidoscope tutorial and copied the settings and properties (not just the include paths...).
QUESTION
I'm trying to make the default selection when the application loads in the "Manufacturer drop down to be "ALL." Currently, the option is blank when the user loads into the application. Does anyone know how you would do this when you allow for multiple inputs?
Here's some example data to use:
...ANSWER
Answered 2021-Nov-18 at 16:01The link I provided in the comment above provides the answer you need. You just didn't implement it correctly. To specify a default for a selectInput
with multiple=TRUE
, you need to provide a vector of default values, not a scalar.
Here is a MWE to demonstrate.
QUESTION
I have a problem where the x-axis values (the manufacturers listed on the heat map) are overlapping with each other due to the number of manufacturers in the dataset. Is there a way to dynamically change the size of these x-axis tick labels/values so they don't overlap with each other when using shiny/flexdashboard? What I mean by "dynamic" is for the size of the x-axis tick values (i.e. the manufacturers) to change based on the user's selection in the drop down. If there are other ways to deal with this problem other than dynamically resizing the x-axis tick values, I am open to it as well.
Here is the data:
...ANSWER
Answered 2021-Nov-04 at 16:57You could do this by adjusting your plot function to have its formatting change with the number of categories it needs to show. Here, I make the size of the axis text adjust to the number of categories.
QUESTION
When I convert from ggplot to plotly, it seems that the dates on the facet plot does not quite fit the page. I'm looking to get more space between the end of the page and the dates on x-axis on the last faceted plot. I've tried to dynamically do this but it doesn't seem to work. Does anyone know of way to fix this problem?
Here is my code:
...ANSWER
Answered 2021-Oct-26 at 17:31Not exactly sure what you mean by "x-axis is cut off" (since it is pretty clear from your picture that in fact the x-axis and tick values etc can be seen).
What I do see as a problem is that your Dates
column is character. You can fix this with:
QUESTION
I know my question is really common question but I did not find the right solution. I have fetched Event from open API. The api gives multiple events and also there are startDate
& endDate
. When I fetched the data, it gives all events but the start dates are not sorted. I want to make one helper function which will sort data by start date and return an Arrays of sort date. But I could not able to do that. I used javascript getTime
for startDate and endDate and compare with them and tried to return the sortData but could not able to do that.
PS: for date validation I am using date-fns
Here is my code and I did not share my wrong approach
.
ANSWER
Answered 2021-Sep-08 at 13:18This is a trivial sort with standard text sorting.
No need to convert the date
QUESTION
I am following along with the LLVM Kaleidoscope Tutorial (Ch. 3), and am encountering errors (undoubtedly from my Makefile) after attempting to link LLVM IR libraries. My Makefile and project structure:
...ANSWER
Answered 2021-Aug-08 at 16:12Your question is, in fact, a duplicate of the #2 answer there.
When you want to create an object file you MUST use the -c
option. That's what the -c
option means.
If you don't want "a plethora of warning messages saying the linker inputs/arguments are unused" then, you know, don't add the linker inputs and arguments when you generate object files! Those arguments are for linking, not compiling.
Your .o
rules should be:
QUESTION
I am following LLVM Kaleidoscope tutorial, 3rd chapter and it seems that additional information is being printed out on compiled code when an operation is run.
...ANSWER
Answered 2021-May-25 at 17:16The reason you're getting a Parsed a top-level expr
is because you most likely changed that string yourself.
If you visit the body for HandleTopLevelExpression
, you see where the tutorial prints this message.
https://llvm.org/docs/tutorial/MyFirstLanguageFrontend/LangImpl03.html#full-code-listing
The printing of LLVM IR to stderr is done with various llvm::Value::print
, called on the line below the one where it writes Read top-level expression
.
To conclude, your code is missing parts from the code listing in the tutorial

QUESTION
I am trying to get a llvm::Module with a global variable to compile with the KaleidoscopeJIT Compiler, however, I get an error in the symbol lookup from the JIT compiler. (KaleidoscopeJIT.h source code from https://github.com/llvm-mirror/llvm/blob/master/examples/Kaleidoscope/include/KaleidoscopeJIT.h )
Upon inspection of the Symbol Table in the LegacyRTDyldObjectLinkingLayerBase, I indeed see that the global variable has not been added to Symbol table. Is this because the global variable is uninitialized? If so how should I specify an initializer for a struct using the llvm C++ api?
I have an IR code generated that looks like this
...ANSWER
Answered 2020-Dec-10 at 15:42The problem seems to be that uninitialized global variables are somehow optimized out and not added to the symbol table.
A quick work around to ensure that the variable gets added to the symbol table is to initialize it with an "Undefined value".
The following code allows to do such an initialization with the c++ api
QUESTION
ANSWER
Answered 2020-Dec-03 at 17:23Do you mean when the user type the first letter and then press enter for example?
If so, you can remove tags which are not in the source list by return false
in the beforeTagSave
callback.
