Functions to implement AnVIL gadget interfaces

Description

Functions documented on this page are primarily intended for package developers wishing to implement gadgets (graphical interfaces) to navigating AnVIL-generated tables.

.gadget_run() presents the user with a tibble-navigating gadget, returning the value of DONE_FUN if a row of the tibble is selected, or NULL.

Usage

.gadget_run(title, tibble, DONE_FUN)

Arguments

title

character(1) (required) title to appear at the base of the gadget, e.g., "AnVIL Workspaces".

tibble

a tibble or data.frame to be displayed in the gadget.

DONE_FUN

a function of two arguments, tibble and row_selected. The tibble is the tibble provided as an argument to .gadget_run(). row_selected is the row selected in the gadget by the user. The function is only invoked when the user selects a valid row.

Value

.gadget_run() returns the result of DONE_FUN() if a row has been selected by the user, or NULL if no row is selected (the user presses Cancel, or Done prior to selecting any row).

Examples

## Not run: 
tibble <- avworkspaces()
DONE_FUN <- function(tibble, row_selected) {
    selected <- slice(tibble, row_selected)
    with(selected, paste0(namespace, "/", name))
}
.gadget_run("AnVIL Example", tibble, DONE_FUN)

## End(Not run)

TABLE, DATA, files, bucket, runtime, and disk elements

Description

DEFUNCT - AnVIL GCP functions for TABLE, DATA, files, bucket,

avtable_import_status() queries for the status of an 'asynchronous' table import.

avdata() returns key-value tables representing the information visualized under the DATA tab, 'REFERENCE DATA' and 'OTHER DATA' items. avdata_import() updates (modifies or creates new, but does not delete) rows in 'REFERENCE DATA' or 'OTHER DATA' tables.

avbucket() returns the workspace bucket, i.e., the google bucket associated with a workspace. Bucket content can be visualized under the 'DATA' tab, 'Files' item.

avfiles_ls() returns the paths of files in the workspace bucket. avfiles_backup() copies files from the compute node file system to the workspace bucket. avfiles_restore() copies files from the workspace bucket to the compute node file system. avfiles_rm() removes files or directories from the workspace bucket.

avruntimes() returns a tibble containing information about runtimes (notebooks or RStudio instances, for example) that the current user has access to.

avruntime() returns a tibble with the runtimes associated with a particular google project and account number; usually there is a single runtime satisfiying these criteria, and it is the runtime active in AnVIL.

'avdisks()' returns a tibble containing information about persistent disks associatd with the current user.

Usage

table

character(1) table name as returned by, e.g., avtables().

n

numeric(1) maximum number of rows to return

page

integer(1) first page of iteration

pageSize

integer(1) number of records per page. Generally, larger page sizes are more efficient.

sortField

character(1) field used to sort records when determining page order. Default is the entity field.

sortDirection

character(1) direction to sort entities ("asc"ending or "desc"ending) when paging.

filterTerms

character(1) string literal to select rows with an exact (substring) matches in column.

filterOperator

character(1) operator to use when multiple terms in ⁠filterTerms=⁠, either "and" (default) or "or".

namespace

character(1) AnVIL workspace namespace as returned by, e.g., avworkspace_namespace()

name

character(1) AnVIL workspace name as returned by, eg., avworkspace_name().

job_status

tibble() of job identifiers, returned by avtable_import() and avtable_import_set().

.data

A tibble or data.frame for import as an AnVIL table.

as_path

logical(1) when TRUE (default) return bucket with prefix ⁠gs://⁠ (for avbucket()) or ⁠gs://<bucket-id>⁠ (for avfiles_ls()).

path

For ⁠avfiles_ls(), the character(1) file or directory path to list. For ⁠avfiles_rm()⁠, the character() (perhaps with length greater than 1) of files or directory paths to be removed. The elements of ⁠path⁠can contain glob-style patterns, e.g.,⁠vign*'.

full_names

logical(1) return names relative to path (FALSE, default) or root of the workspace bucket?

recursive

logical(1) list files recursively?

source

Details

avfiles_backup() can be used to back-up individual files or entire directories, recursively. When recursive = FALSE, files are backed up to the bucket with names approximately paste0(destination, "/", basename(source)). When recursive = TRUE and source is a directory ⁠path/to/foo/', files are backed up to bucket names that include the directory name, approximately ⁠paste0(destination, "/", dir(basename(source), full.names = TRUE))⁠. Naming conventions are described in detail in ⁠gsutil_help("cp")'.

avfiles_restore() behaves in a manner analogous to avfiles_backup(), copying files from the workspace bucket to the compute node file system.

Value

avtable_paged(): a tibble of data corresponding to the AnVIL table table in the specified workspace.

avdata() returns a tibble with five columns: "type" represents the origin of the data from the 'REFERENCE' or 'OTHER' data menus. "table" is the table name in the REFERENCE menu, or 'workspace' for the table in the 'OTHER' menu, the key used to access the data element, the value label associated with the data element and the value (e.g., google bucket) of the element.

avdata_import() returns, invisibly, the subset of the input table used to update the AnVIL tables.

avbucket() returns a character(1) bucket identifier, prefixed with ⁠gs://⁠ if as_path = TRUE.

avfiles_ls() returns a character vector of files in the workspace bucket.

avfiles_backup() returns, invisibly, the status code of the gsutil_cp() command used to back up the files.

avfiles_rm() on success, returns a list of the return codes of gsutil_rm(), invisibly.

avruntimes() returns a tibble with columns

DEFUNCT - Workflow configuration

Description

[Deprecated]
Functions on this help page facilitate getting, updating, and setting workflow configuration parameters. See ?avworkflows for additional relevant functionality.

avworkflow_namespace() and avworkflow_name() are utility functions to record the workflow namespace and name required when working with workflow configurations. avworkflow() provides a convenient way to provide workflow namespace and name in a single command, namespace/name.

avworkflow_configuration_get() returns a list structure describing an existing workflow configuration.

avworkflow_configuration_inputs() returns a data.frame template for the inputs defined in a workflow configuration. This template can be used to provide custom inputs for a configuration.

avworkflow_configuration_outputs() returns a data.frame template for the outputs defined in a workflow configuration. This template can be used to provide custom outputs for a configuration.

avworkflow_configuration_update() returns a list structure describing a workflow configuration with updated inputs and / or outputs.

avworkflow_configuration_set() updates an existing configuration in Terra / AnVIL, e.g., changing inputs to the workflow.

avworkflow_configuration_template() returns a template for defining workflow configurations. This template can be used as a starting point for providing a custom configuration.

Usage

avworkflow_namespace(workflow_namespace = NULL)

avworkflow_name(workflow_name = NULL)

avworkflow(workflow = NULL)

avworkflow_configuration_get(
  workflow_namespace = avworkflow_namespace(),
  workflow_name = avworkflow_name(),
  namespace = avworkspace_namespace(),
  name = avworkspace_name()
)

avworkflow_configuration_inputs(config)

avworkflow_configuration_outputs(config)

avworkflow_configuration_update(
  config,
  inputs = avworkflow_configuration_inputs(config),
  outputs = avworkflow_configuration_outputs(config)
)

avworkflow_configuration_set(
  config,
  namespace = avworkspace_namespace(),
  name = avworkspace_name(),
  dry = TRUE
)

avworkflow_configuration_template()

## S3 method for class 'avworkflow_configuration'
print(x, ...)

Arguments

workflow_namespace

character(1) AnVIL workflow namespace, as returned by, e.g., the namespace column of avworkflows().

workflow_name

character(1) AnVIL workflow name, as returned by, e.g., the name column of avworkflows().

workflow

character(1) representing the combined workflow namespace and name, as namespace/name.

namespace

character(1) AnVIL workspace namespace as returned by, e.g., avworkspace_namespace()

name

character(1) AnVIL workspace name as returned by, eg., avworkspace_name().

config

a named list describing the full configuration, e.g., created from editing the return value of avworkflow_configuration_set() or avworkflow_configuration_template().

inputs

the new inputs to be updated in the workflow configuration. If none are specified, the inputs from the original configuration will be used and no changes will be made.

outputs

the new outputs to be updated in the workflow configuration. If none are specified, the outputs from the original configuration will be used and no changes will be made.

dry

logical(1) when TRUE (default), report the consequences but do not perform the action requested. When FALSE, perform the action.

x

Object of class avworkflow_configuration.

...

additional arguments to print(); unused.

Details

The exact format of the configuration is important.

One common problem is that a scalar character vector "bar" is interpretted as a json 'array' ⁠["bar"]⁠ rather than a json string "bar". Enclose the string with jsonlite::unbox("bar") in the configuration list if the length 1 character vector in R is to be interpretted as a json string.

A second problem is that an unquoted unboxed character string unbox("foo") is required by AnVIL to be quoted. This is reported as a warning() about invalid inputs or outputs, and the solution is to provide a quoted string unbox('"foo"').

Value

avworkflow_namespace(), and avworkflow_name() return character(1) identifiers. avworkflow() returns the character(1) concatenated namespace and name. The value returned by avworkflow_name() will be percent-encoded (e.g., spaces " " replaced by "%20").

avworkflow_configuration_get() returns a list structure describing the configuration. See avworkflow_configuration_template() for the structure of a typical workflow.

avworkflow_configuration_inputs() returns a data.frame providing a template for the configuration inputs, with the following columns:

  • inputType

  • name

  • optional

  • attribute

The only column of interest to the user is the attribute column, this is the column that should be changed for customization.

avworkflow_configuration_outputs() returns a data.frame providing a template for the configuration outputs, with the following columns:

  • name

  • outputType

  • attribute

The only column of interest to the user is the attribute column, this is the column that should be changed for customization.

avworkflow_configuration_update() returns a list structure describing the updated configuration.

avworkflow_configuration_set() returns an object describing the updated configuration. The return value includes invalid or unused elements of the config input. Invalid or unused elements of config are also reported as a warning.

avworkflow_configuration_template() returns a list providing a template for configuration lists, with the following structure:

  • namespace character(1) configuration namespace.

  • name character(1) configuration name.

  • rootEntityType character(1) or missing. the name of the table (from avtables()) containing the entitites referenced in inputs, etc., by the keyword 'this.'

  • prerequisites named list (possibly empty) of prerequisites.

  • inputs named list (possibly empty) of inputs. Form of input depends on method, and might include, e.g., a reference to a field in a table referenced by avtables() or a character string defining an input constant.

  • outputs named list (possibly empty) of outputs.

  • methodConfigVersion integer(1) identifier for the method configuration.

  • methodRepoMethod named list describing the method, with character(1) elements described in the return value for avworkflows().

    • methodUri

    • sourceRepo

    • methodPath

    • methodVersion. The REST specification indicates that this has type integer, but the documentation indicates either integer or string.

  • deleted logical(1) of uncertain purpose.

DEFUNCT - Workflow submissions and file outputs

Description

[Deprecated]
avworkflows() returns a tibble summarizing available workflows.

avworkflow_files() returns a tibble containing information and file paths to workflow outputs.

avworkflow_localize() creates or synchronizes a local copy of files with files stored in the workspace bucket and produced by the workflow.

avworkflow_run() submits and runs the workflow of the configuration.

avworkflow_stop() stops the most recently submitted workflow jub from running.

avworkflow_info() returns a tibble containing workflow information, including workflowName, status, start and end time, inputs and outputs.

Usage

avworkflows(namespace = avworkspace_namespace(), name = avworkspace_name())

avworkflow_files(
  submissionId = NULL,
  workflowId = NULL,
  bucket = avbucket(),
  namespace = avworkspace_namespace(),
  name = avworkspace_name()
)

avworkflow_localize(
  submissionId = NULL,
  workflowId = NULL,
  destination = NULL,
  type = c("control", "output", "all"),
  bucket = avbucket(),
  dry = TRUE
)

avworkflow_run(
  config,
  entityName,
  entityType = config$rootEntityType,
  deleteIntermediateOutputFiles = FALSE,
  useCallCache = TRUE,
  useReferenceDisks = FALSE,
  namespace = avworkspace_namespace(),
  name = avworkspace_name(),
  dry = TRUE
)

avworkflow_stop(
  submissionId = NULL,
  namespace = avworkspace_namespace(),
  name = avworkspace_name(),
  dry = TRUE
)

avworkflow_info(
  submissionId = NULL,
  namespace = avworkspace_namespace(),
  name = avworkspace_name()
)

Arguments

namespace

character(1) AnVIL workspace namespace as returned by, e.g., avworkspace_namespace()

name

character(1) AnVIL workspace name as returned by, eg., avworkspace_name().

submissionId

a character() of workflow submission ids, or a tibble with column submissionId, or NULL / missing. See 'Details'.

workflowId

a character(1) of internal identifier associated with one workflow in the submission, or NULL / missing.

bucket

character(1) DEPRECATED (ignored in the current release) name of the google bucket in which the workflow products are available, as ⁠gs://...⁠. Usually the bucket of the active workspace, returned by avbucket().

destination

character(1) file path to the location where files will be synchronized. For directories in the current working directory, be sure to prepend with "./". When NULL, the submissionId is used as the destination. destination may also be a google bucket, in which case th workflow files are synchronized from the workspace to a second bucket.

type

character(1) copy "control" (default), "output", or "all" files produced by a workflow.

dry

logical(1) when TRUE (default), report the consequences but do not perform the action requested. When FALSE, perform the action.

config

a avworkflow_configuration object of the workflow that will be run. Only entityType and method configuration name and namespace are used from config; other configuration values must be communicated to AnVIL using avworkflow_configuration_set().

entityName

character(1) or NULL name of the set of samples to be used when running the workflow. NULL indicates that no sample set will be used.

entityType

character(1) or NULL type of root entity used for the workflow. NULL means that no root entity will be used.

deleteIntermediateOutputFiles

logical(1) whether or not to delete intermediate output files when the workflow completes.

useCallCache

logical(1) whether or not to read from cache for this submission.

useReferenceDisks

logical(1) whether or not to use pre-built disks for common genome references. Default: FALSE.

Details

For avworkflow_files(), the submissionId is the identifier associated with the submission of one (or more) workflows, and is present in the return value of avworkflow_jobs(); the example illustrates how the first row of avworkflow_jobs() (i.e., the most recently completed workflow) can be used as input to avworkflow_files(). When submissionId is not provided, the return value is for the most recently submitted workflow of the namespace and name of avworkspace().

avworkflow_localize(). type = "control" files summarize workflow progress; they can be numerous but are frequently small and quickly syncronized. type = "output" files are the output products of the workflow stored in the workspace bucket. Depending on the workflow, outputs may be large, e.g., aligned reads in bam files. See gsutil_cp() to copy individual files from the bucket to the local drive.

avworkflow_localize() treats ⁠submissionId=⁠ in the same way as avworkflow_files(): when missing, files from the most recent workflow job are candidates for localization.

avworkflow_run() invisibly returns a slightly modified config object. The new config object has an added LastSubmissionId value that identifies the submitted job.

Value

avworkflows() returns a tibble. Each workflow is in a 'namespace' and has a 'name', as illustrated in the example. Columns are

  • name: workflow name.

  • namespace: workflow namespace (often the same as the workspace namespace).

  • rootEntityType: name of the avtable() used to retrieve inputs.

  • methodRepoMethod.methodUri: source of the method, e.g., a dockstore URI.

  • methodRepoMethod.sourceRepo: source repository, e.g., dockstore.

  • methodRepoMethod.methodPath: path to method, e.g., a dockerstore method might reference a github repository.

  • methodRepoMethod.methodVersion: the version of the method, e.g., 'main' branch of a github repository.

avworkflow_files() returns a tibble with columns

  • file: character() 'base name' of the file in the bucket.

  • workflow: character() name of the workflow the file is associated with.

  • task: character() name of the task in the workflow that generated the file.

  • path: charcter() full path to the file in the google bucket.

  • submissionId: character() internal identifier associated with the submission the files belong to.

  • workflowId: character() internal identifer associated with each workflow (e.g., row of an avtable() used as input) in the submission.

  • submissionRoot: character() path in the workspace bucket to the root of files created by this submission.

  • namespace: character() AnVIL workspace namespace (billing account) associated with the submissionId.

  • name: character(1) AnVIL workspace name associated with the submissionId.

avworkflow_localize() prints a message indicating the number of files that are (if dry = FALSE) or would be localized. If no files require localization (i.e., local files are not older than the bucket files), then no files are localized. avworkflow_localize() returns a tibble of file name and bucket path of files to be synchronized.

avworkflow_run() returns config, invisibly. Note that config has an added LastSubmissionId value for the submission ID of the last run workflow.

avworkflow_stop() returns (invisibly) TRUE on successfully requesting that the workflow stop, FALSE if the workflow is already aborting, aborted, or done.

avworkflow_info() returns a tibble with columns: submissionId, workflowId, workflowName,status, start, end, inputs and outputs.


Graphical user interfaces for common AnVIL operations

Description

workspace() allows choice of workspace for subsequent use. It is the equivalent of displaying workspaces with avworkspaces(), and setting the selected workspace with avworkspace().

browse_workspace() uses browseURL() to open a browser window pointing to the Terra workspace.

table() allows choice of table in the current workspace (selected by avworkspace() or workspace()) to be returned as a tibble. It is equivalent to invoking avtables() to show available tables, and avtable() to retrieve the selected table.

workflow() allows choice of workflow for retrieval. It is the equivalent of avworkflows() for listing available workflows, and avworkflow_configuration_get() for retrieving the workflow.

Usage

avworkspace_gadget()

browse_workspace(use_avworkspace = TRUE)

avtable_gadget()

avworkflow_gadget()

Arguments

use_avworkspace

logical(1) when TRUE (default), use the selected workspace (via workspace() or avworkspace() if available. If FALSE or no workspace is currently selected, use workspace() to allow the user to select the workspace.

Value

workspace() returns the selected workspace as a character(1) using the format namespace/name, or character(0) if no workspace is selected.

browse_workspace() returns the status of a system() call to launch the browser, invisibly.

table() returns a tibble representing the selected AnVIL table.

workflow() returns an avworkflow_configuration object representing the inputs and outputs of the selected workflow. This can be edited and updated as described in the "Running an AnVIL workflow within R" vigenette.

Examples

## Not run: 
workspace()
browse_workspace(use_avworkspace = FALSE)
tbl <- table()
wkflw <- avworkflow_gadget()

## End(Not run)

DEFUNCT - DRS (Data Repository Service) URL management

Description

drs_stat() resolves zero or more DRS URLs to their google bucket location.

drs_access_url() returns a vector of 'signed' URLs that allow access to restricted resources via standard https protocols.

drs_cp() copies 0 or more DRS URIs to a google bucket or local folder

Usage

drs_stat(source = character(), region = "US")

drs_access_url(source = character(), region = "US")

drs_cp(source, destination, ..., overwrite = FALSE)

Arguments

source

character() DRS URLs (beginning with 'drs://') to resources managed by the 'martha' DRS resolution server.

region

character(1) Google cloud 'region' in which the DRS resource is located. Most data is located in "US" (the default); in principle "auto" allows for discovery of the region, but sometimes fails. Regions are enumerated at https://cloud.google.com/storage/docs/locations#available-locations.

destination

character(1), google cloud bucket or local file system destination path.

...

additional arguments, passed to gsutil_cp() for file copying.

overwrite

logical(1) indicating that source fileNames present in destination should downloaded again.

Details

drs_stat() sends requests in parallel to the DRS server, using 8 forked processes (by default) to speed up queries. Use options(mc.cores = 16L), for instance, to set the number of processes to use.

drs_stat() uses the AnVIL 'pet' account associated with a runtime. The pet account is discovered by default when evaluated on an AnVIL runtime (e.g., in RStudio or a Jupyter notebook in the AnVIL), or can be found in the return value of avruntimes().

Errors reported by the DRS service are communicated to the user, but can be cryptic. The DRS service itself is called 'martha'. Errors mentioning martha might commonly involve a mal-formed DRS uri. Martha uses a service called 'bond' to establish credentials with registered third party entities such as Kids First. Errors mentioning bond might involve absence of credentials, within Terra, to access the resource; check that, in the Terra / AnVIL graphical user interface, the user profiles 'External Entities' includes the organization to which the DRS uri is being resolved.

Value

drs_stat() returns a tbl with the following columns:

  • fileName: character() (resolver sometimes returns null).

  • size: integer() (resolver sometimes returns null).

  • contentType: character() (resolver sometimes returns null).

  • gsUri: character() (resolver sometimes returns null).

  • timeCreated: character() (the time created formatted using ISO 8601; resolver sometimes returns null).

  • timeUpdated: character() (the time updated formatted using ISO 8601; resolver sometimes returns null).

  • bucket: character() (resolver sometimes returns null).

  • name: character() (resolver sometimes returns null).

  • googleServiceAccount: list() (null unless the DOS url belongs to a Bond supported host).

  • hashes: list() (contains the hashes type and their checksum value; if unknown. it returns null)

drs_access_url() returns a vector of https URLs corresponding to the vector of DRS URIs provided as inputs to the function.

drs_cp() returns a tibble like drs_stat(), but with additional columns

  • simple: logical() value indicating whether resolution used a simple signed URL (TRUE) or auxilliary service account.

  • destination: character() full path to retrieved object(s)

DEFUNCT - gsutil command line utility interface

Description

These functions invoke the gsutil command line utility. See the "Details:" section if you have gsutil installed but the package cannot find it.

gsutil_requesterpays(): does the google bucket require that the requester pay for access?

gsutil_ls(): List contents of a google cloud bucket or, if source is missing, all Cloud Storage buckets under your default project ID

gsutil_exists(): check if the bucket or object exists.

gsutil_stat(): print, as a side effect, the status of a bucket, directory, or file.

gsutil_cp(): copy contents of source to destination. At least one of source or destination must be Google cloud bucket; source can be a character vector with length greater than 1. Use gsutil_help("cp") for gsutil help.

gsutil_rm(): remove contents of a google cloud bucket.

gsutil_rsync(): synchronize a source and a destination. If the destination is on the local file system, it must be a directory or not yet exist (in which case a directory will be created).

gsutil_cat(): concatenate bucket objects to standard output

gsutil_help(): print 'man' page for the gsutil command or subcommand. Note that only commandes documented on this R help page are supported.

gsutil_pipe(): create a pipe to read from or write to a gooogle bucket object.

Usage

gsutil_requesterpays(source)

gsutil_ls(source = character(), ..., recursive = FALSE)

gsutil_exists(source)

gsutil_stat(source)

gsutil_cp(source, destination, ..., recursive = FALSE, parallel = TRUE)

gsutil_rm(source, ..., force = FALSE, recursive = FALSE, parallel = TRUE)

gsutil_rsync(
  source,
  destination,
  ...,
  exclude = NULL,
  dry = TRUE,
  delete = FALSE,
  recursive = FALSE,
  parallel = TRUE
)

gsutil_cat(source, ..., header = FALSE, range = integer())

gsutil_help(cmd = character(0))

gsutil_pipe(source, open = "r", ...)

Arguments

source

character(1), (character() for gsutil_requesterpays(), gsutil_ls(), gsutil_exists(), gsutil_cp()) paths to a google storage bucket, possibly with wild-cards for file-level pattern matching.

...

additional arguments passed as-is to the gsutil subcommand.

recursive

logical(1); perform operation recursively from source?. Default: FALSE.

destination

character(1), google cloud bucket or local file system destination path.

parallel

logical(1), perform parallel multi-threaded / multi-processing (default is TRUE).

force

logical(1): continue silently despite errors when removing multiple objects. Default: FALSE.

exclude

character(1) a python regular expression of bucket paths to exclude from synchronization. E.g., ⁠'.*(\\.png|\\.txt)$"⁠ excludes '.png' and .txt' files.

dry

logical(1), when TRUE (default), return the consequences of the operation without actually performing the operation.

delete

logical(1), when TRUE, remove files in destination that are not in source. Exercise caution when you use this option: it's possible to delete large amounts of data accidentally if, for example, you erroneously reverse source and destination.

header

logical(1) when TRUE annotate each

range

(optional) integer(2) vector used to form a range from-to of bytes to concatenate. NA values signify concatenation from the start (first position) or to the end (second position) of the file.

cmd

character() (optional) command name, e.g., "ls" for help.

open

character(1) either "r" (read) or "w" (write) from the bucket.

Details

The gsutil system command is required. The search for gsutil starts with environment variable GCLOUD_SDK_PATH providing a path to a directory containing a bin directory containingin gsutil, gcloud, etc. The path variable is searched for first as an option() and then system variable. If no option or global variable is found, Sys.which() is tried. If that fails, gsutil is searched for on defined paths. On Windows, the search tries to find ⁠Google\\Cloud SDK\\google-cloud-sdk\\bin\\gsutil.cmd⁠ in the ⁠LOCAL APP DATA⁠, ⁠Program Files⁠, and ⁠Program Files (x86)⁠ directories. On linux / macOS, the search continues with ⁠~/google-cloud-sdk⁠.

⁠gsutil_rsync()': To make ⁠"gs://mybucket/data"⁠match the contents of the local directory⁠"data"' you could do:

gsutil_rsync("data", "gs://mybucket/data", delete = TRUE)

To make the local directory "data" the same as the contents of gs://mybucket/data:

gsutil_rsync("gs://mybucket/data", "data", delete = TRUE)

If destination is a local path and does not exist, it will be created.

Value

gsutil_requesterpays(): named logical() vector TRUE when requester-pays is enabled.

gsutil_ls(): character() listing of source content.

gsutil_exists(): logical(1) TRUE if bucket or object exists.

gsutil_stat(): tibble() summarizing status of each bucket member.

gsutil_cp(): exit status of gsutil_cp(), invisibly.

gsutil_rm(): exit status of gsutil_rm(), invisibly.

gsutil_rsync(): exit status of gsutil_rsync(), invisbly.

gsutil_cat() returns the content as a character vector.

gsutil_help(): character() help text for subcommand cmd.

gsutil_pipe() an unopened R pipe(); the mode is not specified, and the pipe must be used in the appropriate context (e.g., a pipe created with open = "r" for input as read.csv())


DEFUNCT - Copy packages, folders, or files to or from google buckets

Description

[Deprecated]
localize(): recursively synchronizes files from a Google storage bucket (source) to the local file system (destination). This command acts recursively on the source directory, and does not delete files in destination that are not in 'source.

delocalize(): synchronize files from a local file system (source) to a Google storage bucket (destination). This command acts recursively on the source directory, and does not delete files in destination that are not in source.

  api_reference_md5sum = character(),
  api_reference_version = character(),
  api_reference_headers = NULL
)

Arguments

service

character(1) The Service class name, e.g., "terra".

host

character(1) host name that provides the API resource, e.g., "leonardo.dsde-prod.broadinstitute.org".

config

httr::config() curl options

authenticate

logical(1) use credentials from authentication service file 'auth.json' in the specified package?

api_url

optional character(1) url location of OpenAPI .json or .yaml service definition.

package

character(1) (default AnVIL) The package where 'api.json' yaml and (optionally) 'auth.json' files are located.

schemes

character(1) (default 'https') Specifies the transfer protocol supported by the API service.

api_reference_url

character(1) path to reference API. See Details.

api_reference_md5sum

character(1) the result of tools::md5sum() applied to the reference API.

api_reference_version

character(1) the version of the reference API. This is used to check that the version of the service matches the version of the reference API. It is usally set by the service generation function,. e.g., AnVIL::Rawls().

api_reference_headers

character() header(s) to be used (e.g., c(Authorization = paste("Bearer", token))) when retrieving the API reference for validation.

Details

This function creates a RESTful interface to a service provided by a host, e.g., "leonardo.dsde-prod.broadinstitute.org". The function requires an OpenAPI .json or .yaml specifcation as well as an (optional) .json authentication token. These files are located in the source directory of a pacakge, at ⁠<package>/inst/service/<service>/api.json⁠ and ⁠<package>/inst/service/<service>/auth.json⁠, or at api_url.

When provided, the api_reference_md5sum is used to check that the file described at api_reference_url has the same checksum as an author-validated version.

The service is usually a singleton, created at the package level during .onLoad().

Value

An object of class Service.

Examples

.MyService <- setClass("MyService", contains = "Service")

MyService <- function() {
    .MyService(Service("my_service", host="my.api.org"))
}
