kandi X-RAY | skylark Summary
This is the home of the Skylark in Go project. Skylark in Go is an interpreter for Skylark, implemented in Go. Skylark is a dialect of Python intended for use as a configuration language. Like Python, it is an untyped dynamic language with high-level data types, first-class functions with lexical scope, and garbage collection. Unlike CPython, independent Skylark threads execute in parallel, so Skylark workloads scale well on parallel machines. Skylark is a small and simple language with a familiar and highly readable syntax. You can use it as an expressive notation for structured data, defining functions to eliminate repetition, or you can use it to add scripting capabilities to an existing application. A Skylark interpreter is typically embedded within a larger application, and the application may define additional domain-specific functions and data types beyond those provided by the core language. For example, Skylark was originally developed for the Bazel build tool. Bazel uses Skylark as the notation both for its BUILD files (like Makefiles, these declare the executables, libraries, and tests in a directory) and for its macro language, through which Bazel is extended with custom logic to support new languages and compilers.

I know that polr does not give p-values because they are not very reliable. Nevertheless, I would like to add them to my modelsummary (Vignette) output. I know to get the values as follows:

I need help with heatmaps, I am first timer and I usually have problems when coming to frequencies graphs.
I need to create a heatmap with date on x axis, and crepus on y axis. That is fine.
The variable I want for the color is the frequency of all species (speciesname), which would be the total sum of all species of the variable nmb_individuals, obviously by date and crepus value.
When trying it, I get a completely blank heatmap, though the scale looks good:

QUESTION
I'm trying to add floating-point operations to my .bzl file. According to the Bazel globals specification, the float() function should be defined, as per the Starlark specification. However, when I try to add float(), I get the following error,
ERROR: /home/username/code/project/foo.bzl:4:3: name 'float' is not defined
Is there anything else I have to import? I assume that since the float() keyword is defined in the global namespace I wouldn't need to import it. According to the starlark spec page on the Bazel site page, floats are not supported, but this directly conflicts with the float() specification on the global page.
update: running Bazel 3.7.1
...ANSWER
Answered 2021-Jan-09 at 21:46A version of Bazel supporting floating point numbers has not been released yet. Presumably, the version after 4.0 will support them.

I am attempting to read a .xls file into Matlab. I am prohibited from using built-in functions such as xlsread(), textread() and readable(). I am allowed to convert the .xls file to other formats if easier and I have tried the code below using data.txt but to no avail.
I am allowed to use the basic 'fopen', 'fscanf', 'fread' functions. However, I can't seem to figure out how to implement them correctly.

QUESTION
I am writing a simple Bazel rule that uses ctx.actions.run. Unfortunately, I have a hard time understanding inputs param of run action.
The doc says inputs is "a list or depset of the input files of the action". What if my action just runs an executable and passes a few file paths as its arguments ? Suppose I specify the arguments as arguments parameter of the run action. Do I still need to add these file paths to the inputs parameter ? Why ?
ANSWER
Answered 2020-Oct-15 at 16:50The inputs parameter tells Bazel what files to make available to the executable of the action when Bazel runs it. This parameter is important for a few reasons:
It tells Bazel what other actions need to be run to produce the input files for the given action. If you have
Action1 <- Artifact <- Action2, whereAction2producesArtifact, andAction1takesArtifactas an input, Bazel knows to runAction2beforeAction1.It tells Bazel what files to make available in the action sandbox. Otherwise the action won't be able to find any of its input files.
It tells Bazel what files to upload to remote execution workers, if remote execution is being used. Otherwise the file won't be available on the remote machine for the action to read.
The arguments parameter of ctx.actions.run tells Bazel what the command line for the executable of the action is. If your executable takes flags like --input and --output, you'd use arguments to construct a command line like --input artifact1 --input artifact2 --output artifact3.
See this example: https://github.com/bazelbuild/examples/blob/master/rules/actions_run/execute.bzl
QUESTION
I can create a label_flag in Bazel to allow command line flags to in turn be matched with a config_setting in a Bazel BUILD file.
However, I'd like to not hard-code the default value of the label_flag, and instead compute a good default based on the system when evaluating a repository_rule (or some other part of the WORKSPACE file).
The best (but awful) way I've come up with to do this is to have the default value loaded from a .bzl file that is generated using the template function on the repository_ctx.
I feel like generating a new file by doing textual substitutions probably isn't the right way to do this, but I can't find anything else. Ideas? help?
...ANSWER
Answered 2020-Sep-21 at 08:13Generating a bzl file using the repository rule that inspects the host system is the only way to achieve what you need right now. So you're holding it "right" :)
QUESTION
What is the best way to refer to an external package's path in any arbitrary files processed by Bazel?
I'm trying to understand how Bazel preprocesses BUILD and .bzl files. I see instances where strings contain calls to package() and I am wondering how it works (and could not find any relevant documentation). Here is an example of this:
I have a toolchain which BUILD file contains the following expression :
...ANSWER
Answered 2020-Sep-18 at 17:45These directives are expanded by cc_common.create_cc_toolchain_config_info within the cc_toolchain_config rule implementation not any sort of preprocessing on the BUILD file (I.e., "%package(@host_gcc8_glibc//include)%" is literally passed into the cc_toolchain_config rule.) I'm not aware that these special expansions are completely documented anywhere but the source.
