### R Example Execution Error for EQRN (torch dependency)

Source: https://github.com/futureverse/dofuture/blob/develop/revdep/problems.md

The examples for the 'EQRN' package failed to run, specifically due to an issue with the 'torch' library. The error 'Lantern is not loaded' suggests that required 'torch' dependencies are missing and need to be installed using `install_torch()`.

```R
Running examples in ‘EQRN-Ex.R’ failed
The error most likely occurred in:

> ### Name: default_device
> ### Title: Default torch device
> ### Aliases: default_device
> 
> ### ** Examples

### Integrating doFuture with Foreach %dopar% using registerDoFuture()

Source: https://github.com/futureverse/dofuture/blob/develop/README.md

This snippet illustrates the alternative method for integrating 'doFuture' with 'foreach' by registering 'doFuture' as the backend for the '%dopar%' operator. It's useful for adapting existing '%dopar%' code or when using packages that internally rely on '%dopar%' for parallelization.

```R
library(doFuture)
registerDoFuture()
plan(multisession)

y <- foreach(x = 1:4, y = 1:10) %dopar% {
  z <- x + y
  slow_sqrt(z)
}
```

### APIDOC: foreach Scheduling Options (.options.future)

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

Documentation for controlling scheduling and chunking behavior in 'foreach()' loops using the '.options.future' argument. This allows fine-grained control over how iterations are distributed among workers, with fallback to '.options.multicore' if not specified.

```APIDOC
foreach(..., .options.future = list(scheduling = <value>)):
  Description: Controls whether scheduling ("chunking") should take place or not, and if so, how granular it should be.
  Parameters:
    scheduling:
      Type: numeric | logical
      Values:
        1.0 (or TRUE): Elements (iterations) will be split into equally sized chunks such that each backend worker processes exactly one chunk. (Default if not set and .options.multicore not used)
        Inf (or FALSE): Chunking is disabled; each worker processes exactly one element at a time.
        0.0: A single worker processes all elements (other workers will not be used).
        2.0 (or higher): Each worker will process 'value' chunks.
  Fallback: If .options.future is not set, then .options.multicore = list(preschedule = <logical>) (defined by doParallel) is used, where preschedule maps to scheduling. If neither is set, scheduling = 1.0 is used by default.
```

--------------------------------

### Configuring %dopar% to Behave as %dofuture% with `flavor`

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

The `registerDoFuture(flavor = "%dofuture%")` option allows users to make the standard `%dopar%` infix operator behave identically to `%dofuture%`. This is particularly useful when working with existing code or packages that rely on `%dopar%` but you wish to leverage `doFuture`'s specific behaviors.

```R
registerDoFuture(flavor = "%dofuture%")
```

--------------------------------

### Temporarily Registering doFuture Adapter with `with()`

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

The `with(registerDoFuture(), { ... })` construct allows for temporarily using the `doFuture` adapter within a specific block of code. The `local = TRUE` option can be used to register it temporarily within a function scope.

```R
with(registerDoFuture(), {
  # Your foreach code here
})

# Or temporarily within a function:
my_function <- function() {
  with(registerDoFuture(), local = TRUE, {
    # Your foreach code here
  })
}
```

--------------------------------

### DESCRIPTION Meta-information Check Note

Source: https://github.com/futureverse/dofuture/blob/develop/revdep/problems.md

This entry highlights a problem with the `DESCRIPTION` file's meta-information. It indicates that the license stub within the file is not in a valid DCF (Debian Control File) format, which is required for R package metadata.

```Configuration
License stub is invalid DCF.
```

--------------------------------

### Enabling Verbose Output for `foreach` Operations

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

The `.verbose = TRUE` argument can be passed to `foreach()` to enable detailed debugging information. This output is directed to standard error via R's message condition mechanism and is useful for troubleshooting parallel execution issues.

```R
foreach(..., .verbose = TRUE) %dofuture% { # Your parallel task }
```

--------------------------------

### Ensuring Consistent Random Number Generation with `withDoRNG()`

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

The `withDoRNG()` function allows for evaluating a `foreach %dopar%` expression with `doRNG::registerDoRNG()` temporarily set. This ensures consistent and reproducible random number generation across parallel iterations.

```R
withDoRNG({
  # Your foreach %dopar% expression here
  # e.g., foreach(i = 1:10) %dopar% { rnorm(1) }
})
```

### APIDOC: doFuture.foreach.export Option

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

Documentation for the 'doFuture.foreach.export' option, which controls how global variables are identified and exported for 'foreach()' loops when using 'doFuture'. It details various modes for managing global variable visibility and export behavior.

```APIDOC
doFuture.foreach.export:
  Description: Controls how global variables are identified and exported for foreach() loops.
  Values:
    "manual": Strictly follows the .export argument of foreach(). Disables future + globals framework.
    "automatic-unless-.export" (Defunct): Previously a default, now falls back to "export-and-automatic".
    "automatic" (Defunct): Previously a default, now falls back to "export-and-automatic".
    "export-and-automatic": Uses the future framework for global identification, potentially combining with .export.
    "export-and-automatic-with-warning": Similar to "export-and-automatic", but produces a warning listing globals potentially missing from the .export argument. Useful for developers.
```

### Parallelizing R Foreach Loops with %dofuture% Operator

Source: https://github.com/futureverse/dofuture/blob/develop/README.md

This snippet demonstrates the recommended way to use 'doFuture' with 'foreach' by employing the '%dofuture%' operator. It shows how to set up a 'multisession' plan and perform a parallelized loop, with global identification, RNG, and error handling managed by the future ecosystem.

```R
library(doFuture)
plan(multisession)

y <- foreach(x = 1:4, y = 1:10) %dofuture% {
  z <- x + y
  slow_sqrt(z)
}
```

### R Package simtrial Dependency Note

Source: https://github.com/futureverse/dofuture/blob/develop/revdep/problems.md

Notes an unused namespace import, 'gsDesign2', in the 'simtrial' package's R code, reminding that all declared imports should be utilized.

```Shell
Namespace in Imports field not imported from: ‘gsDesign2’
  All declared Imports should be used.
```

--------------------------------

### Using the %dofuture% Operator for Parallel Execution

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

The `%dofuture%` operator provides an alternative to `%dopar%` for parallel processing with `foreach`, offering direct control and leveraging the future ecosystem for consistent random number generation, global identification, and error handling. It eliminates the need for explicit `registerDoFuture()` calls.

```R
y <- foreach(x = 1:3) %dofuture% { slow_fcn(x) }
```

--------------------------------

### Controlling Future Options with Infix Operators (%stdout%, %conditions%)

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

Future operators like `%stdout%` and `%conditions%` can be used directly with `foreach` expressions to control corresponding `options.future` arguments. This provides a more concise syntax for managing standard output and conditions during parallel execution.

```R
y <- foreach(i = 1:3) %dopar% { my_fun(i) } %stdout% FALSE
# Equivalent to:
y <- foreach(i = 1:3, .options.future = list(stdout = FALSE)) %dopar% { my_fun(i) }
```

--------------------------------

### APIDOC: future.globals.resolve Option

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

Documentation for the 'future.globals.resolve' option, which dictates whether global variables should be resolved. 'doFuture' now respects this option, ensuring consistency with other 'future' frontends.

```APIDOC
future.globals.resolve:
  Description: Controls whether globals should be resolved.
  Behavior: doFuture now respects this option instead of being hardcoded to always resolve globals (future.globals.resolve = TRUE), making it consistent with other future frontends.
```

--------------------------------

### APIDOC: future.globals.maxSize Option

Source: https://github.com/futureverse/dofuture/blob/develop/NEWS.md

Documentation for the 'future.globals.maxSize' option, which defines the maximum total size of globals allowed per future (or 'chunk'). This option now scales dynamically with the number of elements processed, ensuring consistent protection regardless of chunking strategy.

```APIDOC
future.globals.maxSize:
  Description: Maximum total size of globals allowed per future ("chunk").
  Behavior: Scaled up by the number of elements processed by the future ("chunk"), making the protection approximately invariant to the amount of chunking done by foreach.
```

### R.rsp Script to Clean Markdown Vignette Content

Source: https://github.com/futureverse/dofuture/blob/develop/incl/OVERVIEW.md

This R.rsp script reads a markdown file, typically a vignette, and performs text manipulation to clean its content. It identifies and removes all lines preceding the first H2 header (##) and all lines following the first horizontal rule (---), then outputs the remaining cleaned markdown. This process is useful for extracting the primary content body of a document, discarding boilerplate headers and footers.

```R
<%
## Reuse the future vignette
md <- R.rsp::rstring(file="vignettes/doFuture-1-overview.md.rsp", postprocess=FALSE)

## Drop the header, i.e. anything before the first "H2" header
md <- unlist(strsplit(md, split="\n", fixed=TRUE))
row <- grep("^## ", md)[1]
if (!is.na(row)) md <- md[-seq_len(row-1)]

## Drop the footer, i.e. anything after the first horizontal line
row <- grep("^---", md)[1]
if (!is.na(row)) md <- md[seq_len(row-1)]

## Output
cat(md, sep="\n")
%>
```
