write_clip()
calls on Windows are
modified to work well with R’s shift to supporting UTF-8 as a native
encoding on Windows. Thank you to @yutannihilation for the PR. Read
more here: https://github.com/mdlincoln/clipr/issues/62--output
flag, which prevents
RStudio from hanging when calling clipr functions on a system running
certain Linux window managers. Thank you to @cgillespie and @kevinushey for identifying the bug and
the solution, and to @hannahcgunderman for help in
testing.Thank you to @jennybc for prompting these changes:
clipr_available()
will first explicitly check if it is
being run non-interactively, and if so, if the CLIPR_ALLOW
environment variable has been set. This will hopefully prevent starting
spurious Linux processes during CRAN tests.read_clip()
now does
the same interactive/envvar check that write_clip()
does.Thank you to @wangyuchen for making the following suggestions:
To make clipr more pipe-friendly, write_clip()
now
defaults to return_new = FALSE
, and will instead return the
initial object that was passed in. To get the old behavior, pass
return_new = TRUE
In an effort to make write_clip()
and
read_clip_tbl()
more symmetrical, write_clip()
now defaults to writing out row and column names when they
exist.
Introduces write_last_clip()
, a wrapper function for
write_clip(.Last.value)
To comply with CRAN policy, write_clip()
will now
error by default if run in a non-interactive session. Non-interactive
use must be explicitly enabled by setting an environment variable
CLIPR_ALLOW=TRUE
.
Documented that the default behavior when writing matrices to
write_clip()
is col.names = FALSE
dr_clipr()
, which gives informative
suggestions for software and configuration requirements when accessing
the clipboard on X11-based systems.Suppress an erroneous warning on OS X / X11 systems when trying to write an empty string to the clipboard.
Fix error when NA
is passed to
write_clip()
. This will now write "NA"
to the
clipboard.
Fix error when passing NULL
or an empty vector
(e.g. character(0)
). This will now write ""
to
the clipboard.
Fixes a breaking bug that caused clipr_available
to
erroneously return FALSE
. Thank you to @krivit for catching
this.
Introduces better testing of clipr_available
to
properly evaluate it on Travis CI.
Introduces clipr_available
which checks to see if
the system clipboard is writeable/readable. This may be useful if you
are developing a package that relies on clipr and need to ensure that it
will skip tests on machines (e.g. CRAN, Travis) where the system
clipboard may not be available. Thank you to @jennybc for this suggestion.
Implements genuine testing of clipr functionality with thanks to some deft environment variable settings added by @jennybc.
Two RStudio addins: one to copy the value returned when a highlighted expression is evaluated, and another that copies the console output.
Introduces read_clip_tbl
, a convenience function
that takes tab-delimited text from read_clip
(such as that
copied from a spreadsheet) and parses it with read.table
.
Thank you to Steve Simpson (@data-steve) for the original
PR.
write_clip(object_type = "table")
has a new internal
implementation (writing to a temporary file rather than using
capture.output
) which should dramatically shorten the time
it takes to write very large tables to the clipboard. Thank you to @r2evans for this
suggestion.
Several changes to write_clip
- The separator to be
used when writing a character vector can now be explicitly declared
using breaks
. breaks=NULL
will default to
system-specific line breaks for both vectors and tables. -
write_clip
will default to formatting data.frames and
matrices with write.table
, allowing easy pasting of tabular
objects into programs like Excel. Option object_type="auto"
will check the object type to decide on the correct formatting, or the
user may explicitly state object_type="table"
or
object_type="character"
. - clipr will default to sane
system-specific options for write.table()
, however you may
pass any custom desired options via write_clip
-
return_new=TRUE
(the default behavior) will return the
formatted character string that was passed to the system clipboard,
while write_clip(return_new=FALSE)
will return the original
object.
Introduces clear_clip
, a wrapper function for
write_clip("")
for easy clearing of the system
clipboard.
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
