progArgs() now accepts argument ifnotfound
specifying what to do when no program arguments are found.
this.path(original = TRUE) used inside a "gzfile",
"bzfile", "xzfile", or "fifo" connection will no
longer return a ‘file://’ URL.
this.path() once again works in ‘Rgui’ running in a
Japanese or Turkish locale.
with_init.file() now accepts a braced expression, the
sub-expressions of which are evaluated and auto-printed.
this.path() is now compatible with function
utils::Sweave().
this.path() is now compatible with background jobs in
‘RStudio’.
Added with_script_path() which sets the current script in
package:box to this.path(), then evaluates its
argument, most commonly a package:box import statement.
Added make_fix_file() which makes a function that constructs
file paths, starting with the project root of this.dir().
set.sys.path.jupyter() is defunct and should be replaced
with set.jupyter.path().
fileArgs() is defunct and should be replaced
with progArgs().
this.path() now works correctly in the site-wide startup
profile file.
this.path() now works correctly with source file aliases.
Updated shFILE() to work better with older versions of R.
Improved LINENO(), specifically sys.LINENO(), when
comparing paths to determine the appropriate source reference.
this.proj() now throws an error that it does not work for
URL pathnames.
Removed the restriction that reset.proj() could only be
called from a top level context.
withArgs() will now be found anywhere on the stack as long
as it and the source()-like function are called in the same frame.
e.g. withArgs(try(source("./example.R")), 1, 2, 3) now works as
intended.
Unified behaviour of is.main() across all GUIs.
All promises are now braced, giving a more sensible call stack in case of warnings / / errors.
Namespaces loaded with requireNamespace() are now loaded
quietly.
sys.srcref() now works when passed as a non-forced argument
to a function containing source references. By extension,
this.path() and LINENO() now work as well.
Previously defunct functions this.path2(),
this.dir2(), this.dir3(), and normalized.shFILE()
were removed entirely.
this.path() is now compatible with GUI ‘Emacs’.
Active bindings FILE and LINE have
been converted to regular bindings FILE() and LINE()
after the unfortunate realization that active binding functions are
always evaluated in the global environment.
this.path() works significantly better with source
references.
this.path() is now compatible with package
package:targets.
Added with_site.file() and with_init.file() that
allow this.path() to be used within the site-wide startup
profile file or a user profile.
this.path(contents = TRUE) in ‘Rgui’ will now return
the contents of an unsaved document, or return the unsaved changes of a
saved document.
Added set.gui.path() for implementing sys.path() for
arbitrary GUIs.
this.path() is now compatible with function
shiny::runApp().
this.path() is now compatible with function
plumber::plumb().
Added tryCatch3() which accepts condition expressions
instead of condition handlers. Added active binding
last.condition which will be the last thrown-and-caught
condition in tryCatch3().
When tryCatch2() and tryCatch3() catch a condition
but the respective handler / / expression is missing, the next
non-missing handler / / expression is used instead.
set.env.path() and set.src.path() now return their
input instead of returning NULL.
set.src.path() now accepts an expression vector containing a
source file.
this.path() was misleading users into believing it returns
the path of the script in which it is written. In actuality, it returns
the path of the executing script. As such, it was renamed to
sys.path() in accordance with the other call stack inspection
functions sys.call(), sys.frame(), sys.nframe(),
and sys.function(). Related functions that were renamed:
| old | new | |
| [1,] | this.dir | sys.dir |
| [2,] | here | sys.here |
| [3,] | this.proj | sys.proj |
| [4,] | rel2here | rel2sys.dir |
| [5,] | LINENO | sys.LINENO |
| [6,] | try.this.path | try.sys.path |
| [7,] | set.this.path | set.sys.path |
| [8,] | unset.this.path | unset.sys.path |
| [9,] | set.this.path.jupyter | set.sys.path.jupyter |
this.path() was replaced by a function that returns the path of
the script in which it is written. It does this by looking for a source
reference with an appropriate source file, or inspects the environment
in which it is called for an associated path, or returns the path of
the executing script, as before. Related functions that were replaced:
| [1] | this.dir | here | ici | this.proj |
| [5] | rel2here | LINENO | try.this.path | check.path |
| [9] | check.dir | check.proj |
Added env.path() for determining the path associated with
the top level environment. Also added env.dir(),
env.here(), env.proj(), rel2env.dir(),
env.LINENO(), and try.env.path().
Added src.path() for determining the path associated with
its source reference. Also added src.dir(), src.here(),
src.proj(), rel2src.dir(), src.LINENO(), and
try.src.path().
Added set.env.path() and set.src.path() to work along
side set.sys.path().
this.path() now accepts arguments n,
envir, matchThisEnv, and
srcfile to finely control how the path will be
retrieved.
Added rel2proj() for turning absolute paths into relative
paths against the script's project root. Also added
rel2sys.proj(), rel2env.proj(), and
rel2src.proj().
set.sys.path() now accepts argument ofile
specifying the original file argument. This overwrites the value
returned by sys.path(original = TRUE).
Added active bindings FILE and LINE
linking to try.this.path() and LINENO() to be used in a
similar manner to the macros __FILE__ and
__LINE__ in C.
Added path.functions() which accepts a file path and
constructs a set of path-related functions, similar to
this.path() and associated.
inside.source() and set.this.path() are defunct and
should be replaced with set.sys.path().
unset.this.path() is defunct and should be replaced with
unset.sys.path().
set.this.path.jupyter() is defunct and should be replaced
with set.sys.path.jupyter().
reset.this.proj() is defunct and should be replaced with
reset.proj().
Fixed display issues in LaTeX and plain text documentation.
reset.proj() now has environment
<environment: namespace:this.path> as do all other exported
functions.
Fixed sys.path(contents = TRUE) in ‘RStudio’ and
‘VSCode’ having a trailing blank string.
Fixed sys.path(contents = TRUE) in ‘Jupyter’ if the
executing script had yet to be determined.
Fixed sys.path(original = NA) in ‘RStudio’,
‘VSCode’, and ‘Jupyter’ saying
missing value where TRUE/FALSE needed.
Fixed relpath() on Windows when comparing paths with network
shares.
Fixed package:this.path used in the site-wide startup profile
file, a user profile, or the function .First() on Windows in
‘RStudio’.
