frictionless 1.1.0
Changes for users
- New function
print()
prints a human-readable summary of the Data Package, rather than a (long) list (#155).
read_package()
no longer returns a message regarding rights and credit (#121). If package$id
is a URL (e.g. a DOI) it will be mentioned in print()
.
add_resource()
accepts additional arguments via ...
. These are added as (custom) properties to the resource and are retained in write_package()
(#195).
read_resource()
now supports column selection via the col_select
argument from readr::read_delim()
. This can vastly improve reading speed (#123). Tidy selection is not supported.
- Error and warning messages use semantic colours for variables, parameters, fields, etc.
readr::problems()
is included in NAMESPACE so you don’t have to load readr to inspect parsing issues. The function is mentioned in the documentation of read_resource()
(#129).
Changes for developers
- A Data Package object (
package
) now has a datapackage
class (#184). This enables a custom print()
function (see above). check_package()
will warn if the class is missing, so previously saved Data Package objects (without the class) will generate a warning.
check_package()
is now a public function, so it can be used in your package (#185). This and the other check_
functions return the first argument silently (rather than TRUE
), so they can be chained.
create_package()
now accepts a descriptor
argument so that a Data Package object can be created from an existing object (#184). It will always validate the created object with check_package()
.
cli::cli_abort()
, cli::cli_warn()
and cli::cli_inform()
are used for all errors, warnings, and messages (#163). This has several advantages:
- Messages use semantic colours for variables, parameters, fields, etc.
- Messages and warnings can be silenced with a global or local option, see this blog post.
- Each call has an rlang class, e.g.
frictionless_error_fields_without_name
, making it easier to test for specific errors.
- glue and assertthat are removed as dependencies (#163). The functionality of glue is replaced by cli, while
assertthat::assert()
calls are now if ()
statements.
- rlang is added as dependency (#192). It is already used by other dependencies.
- frictionless now depends on R >= 3.5.0.
Other changes
- The package now adheres to the requirements of checklist, so that
.zenodo.json
can be created with checklist::update_citation()
.
- Add Pieter Huybrechts as author and Kyle Husmann as contributor. Welcome both!
frictionless 1.0.3
- Add stringi to
Suggests
. It was removed as a dependency from rmarkdown 2.26, resulting in “stringi package required for encoding operations” build errors on CRAN (#176).
frictionless 1.0.2
- Add
skip_if_offline()
to selected tests and verbosely include output in vignette examples, to avoid CRAN errors caused by timeouts (#116).
frictionless 1.0.1
- Rebuild documentation for compatibility with HTML5 on request of CRAN.
- Add funder information.
frictionless 1.0.0
frictionless 0.11.0
add_resource()
now sets format
, mediatype
and encoding
for added CSV file(s) (#78).
add_resource()
now supports adding schema
via path or URL.
write_package()
now supports added data to be gzip compressed before being written to disk (#98).
read_resource()
will now warn rather than error on unknown encoding (#86).
package
objects no longer have or require the custom attribute resource_names
, use new function resources()
instead (#97).
package
objects no longer have or require the custom attribute datapackage
, making it easier to edit them as lists (with e.g. append()
).
frictionless 0.10.0
add_resource()
now supports adding CSV file(s) directly as a resource. This skips reading/handling by R and gives users control over path
(#74).
- CSV files in a remotely read package (like
example_package
) are now downloaded when writing with write_package()
, rather than being skipped. This is more consistent with locally read packages. The behaviour for resources with a path
containing URLs (only) and resources with data
remains the same (no files are written). The write behaviour is better explained in the documentation (#77).
write_package()
now silently returns the output rather than input package
.
create_package()
will set "profile" = "tabular-data-package"
since packages created by frictionless meet those requirements (#81).
create_schema()
interprets empty columns as string
not boolean
(#79).
read_package()
can now read from a datapackage.yaml
file.
read_resource()
now accepts YAML Table Schemas and CSV dialects.
add_resource()
/create_schema()
’s df
argument is renamed to data
.
example_package
’s observations
resource now has URLs as path
to serve as an example for that.
frictionless 0.9.0
- Add vignette with overview of functionality (#60).
- Prepare frictionless for rOpenSci submission.
