I am trying to create a documentation for a Julia module using Documenter.jl. Now I imported a module which documenter cannot find for some reason. More explicitly: I imported SparseArrays.jl via import SparseArrays and am referencing SparseArrays.AbstractSparseArray in a docstring. (I also have SparseArrays.jl installed.) Yet I get ERROR: LoadError: UndefVarError: SparseArrays not defined. What's the reason and how can I fix this?
EDIT: This is what the relevant parts of the code look like:
module ExampleModule
import SparseArrays
include("example.jl")
end
example.jl:
"""
f
does stuff.
"""
function f(x::SparseArrays.AbstractSparseArray)
return
end
index.md:
```#docs
f(x::SparseArrays.AbstractSparseArray)
```
Most likely you have imported it in a separate code block. See here for an explanation of the issue.
Also you might need to add import SparseArrays in setup code as explained here. This is needed if e.g. you have doctests inside docstrings.
Here is an example how it is done in DataFrames.jl (in general DataFrames.jl has doctests enabled both in docstrings and in documentation code so you can have a look at the whole setup we have there).
If this is not the reason then could you please share your code in the question so that it can be inspected?

I just put some of my code from a/b.dart to a/b1.dart file and now I started getting lot of errors on importing.
Is there any command or any other fix to import all a/b1.dart file in these files instead of manually opening each file and importing one by one.
I understand that a function or a property can be defined in more than two files and Dart can't make the right choice but if a function or property is defined in just one place, I think there must be some way to import it except searching for a/b.dart and replacing it with a/b.dart + a/b1.dart and then optimizing all imports.
As much as I am aware, Plugins/Extensions for your specific IDE (for dart) can be found that will help you with this problem.
I would recommend using dartdev tools - dartfix
The error occurs when I use the library in another library.
Library import is working fine in the app but not working within libraries.
And not able to generate the build of a library.
All libraries are publishable.
Error:
Nrwl.v13 Files Structure within lib folder:
Very difficult to debug. It can be related to circular dependency issue. Are you sure you don't import code from library which import code from the same library ?
A import B
B import A
If this is the case, you should handle this by creating a C library which will be imported by A and B or find a solution for the A or B which will not depend on each other.
Code example will be helpful for help you.
From https://github.com/nrwl/nx/issues/10785#issuecomment-1158916416:
There seems to have been an issue with a migration that was scheduled
for a version but the migration itself was released in another
version, so that might have caused the migration to not run in some
scenarios. That migration should have added the following in nx.json
for anyone having their nx.json extending from
nx/presets/core.json or nx/presets/npm.json:
{
...
"pluginsConfig": {
"#nrwl/js": {
"analyzeSourceFiles": true
}
}
}
Could you please add the above snippet to your nx.json and try again? If after applying the change it doesn't pick
it up immediately, run nx reset and then try again.
This didn't work for me though, so I opened nx issue #11583: library importing other library using wildcard path mapping fails with "is not under 'rootDir'"
I had this issue in one of our monorepo and it was caused by the fact that one of our library's name wasn't valid. We had something like #organisation/test-utils/e2e which we ended up renaming to #organisation/test-utils-e2e (take note of the / usage).
I'm having trouble using the Backendless plugin for Flutter.
I include
import 'package:backendless_sdk/backendless_sdk.dart';
(as per the instructions) and can then use e.g. Backendless.UserService. But if I try to generate a user to register, e.g.:
var user = new BackendlessUser();
user.setEmail("info#example.org");
user.setPassword("password");
Backendless.UserService.register(user);
I get an error Undefined class 'BackendlessUser' on the first line. This class is defined in src/modules/user_service.dat, which is exported by src/modules/modules.dartlike this:
library modules;
export 'cache.dart';
...
export 'user_service.dart';
which in turn is imported by backendless_sdk.dart like this:
import 'package:backendless_sdk/src/modules/modules.dart';
I would have thought that it would get imported indirectly by the import of backendless_sdk.dart, but apparently not. When I import it explicitly (with the same import statement, but now in my own code and not just indirectly in backendless_sdk.dart), I get a warning Don't import implementation files from another package. But it's not an implementation file; it's exported as part of the public API (at least that's what I understand the export statement to mean).
The Dart tutorial for creating packages suggests to place the export statements directly under lib, not in lib/src, so I'm wondering whether this is an error in the structure of the plugin, or whether I'm doing something wrong.
I'd be grateful both for a solution to this particular problem and also for pointers to how I can better understand packages, libraries, imports and exports in dart; unfortunately I don't find the language specification particularly helpful in this regard.
(The error and the warning are the same whether I use flutter analyze or IntelliJ IDEA.)
The problem has been fixed in the 0.0.3 version of the plugin. Please update the backendless_sdk version in your pubspec.yaml.
You can include the only one import now:
import 'package:backendless_sdk/backendless_sdk.dart';
Please also note, that there are some changes in the syntax. So for your example you should use:
var user = new BackendlessUser()
..email = "info#example.org"
..password = "password";
Backendless.userService.register(user);
Thanks for using Flutter SDK and pointing out this issue.
It's indeed the problem in the structure of the plugin. The Backendless team is aware of it and this problem will be fixed in the next release of the plugin.
For now you can import explicitly and suppress the warning.
I've already Google'd for an answer, since this is a common problem, but all the replies point in using alternatives instead of explaining why this doesn't work, so I'm asking here.
I put this code in my Atom's init.coffee script:
beautify = require('js-beautify').html
But Atom fails with Failed to load init.coffee and Cannot find module 'js-beautify'. Curiously enough, this works on a package and this works if I type the exact same code on Atom's console.
Of course, I could write a package for this, in fact there are a couple available, this is just an example because I want to learn how to require modules from init.coffee for future tweaks.
Thanks a lot!
When you require() from init.coffee, Atom looks for those modules in its own path. An example of where you might want to do that is if you had oni = require('oniguruma') to get access to regular expression functions.
In order to get to js-beautify, you have to specify its complete path. So far, only explicitly declaring the entire absolute path has worked for me:
beaut = require 'C:\\Users\\<username>\\.atom\\packages\\atom-beautify\\node_modules\\js-beautify'
console.log beaut
In practice, the most reliable way to use a module like this is to globally install it so that you can link to your global NPM folder. Linking to a module inside a package will break if the package is ever uninstalled.
I have one Fay file which is the heart of my program, however I need some helpers for my logic, for instance a method to replace substrings. From what I understand, if I need such methods which are offered by many Haskell libraries from Hackage directly, I can't use those Haskell libraries, but I must copy-paste the code in my project. So it's what I did, I copy-pasted a "replace" function together with other helpers from the MissingH library in a new file in my project: Utils.hs.
That Utils.hs compiles without problems with Fay. Also I import it in my main Fay file and I get a JS file for the main project file without problems. However at runtime I get the following error:
ReferenceError: Utils$$36$ is not defined
I don't think that Fay will include the code from the helper file in my main JS file, so I'm including both JS files in the loading HTML. And to make even more sure that when I load the main file, that the utils file is loaded, I load it like that:
$.getScript("Utils.js", function(){
$.getScript("FayConfig.js");
});
But despite this I still get the error. I tried compiling the Utils.hs with "--library" but it didn't help.
So my question is, which setup do I need to achieve that the generated JS will find the helper functions that I put in another HS file, knowing that at compile-time, Fay (apparently) finds them without problems? Is there an example of such a setup online? Most of the Fay uses that I found have all the code in a single HS file, though they often use external Fay code from cabal, as with fay-jquery. In my case, setting up a cabal project just for these simple helpers would be overkill.
Which version of Fay are you using (fay --version)? It seems like you are using a version older than
0.16 where forgetting import Prelude wouldn't give any warnings, see this closed ticket. So upgrade fay and/or add import Prelude.
We're also considering renaming operators in the produced output to make error messages like these easier to understand.
You do not need to invoke fay several times, fay outputs all dependencies into the same js file. So there's no difference from using a cabal package in that regard.
Hope this helps, otherwise please give me a way to reproduce this.
