this.path News CHANGES IN this.path 2.4.0 (2024-02-16): SIGNIFICANT USER-VISIBLE CHANGES: * with_init.file() now accepts a braced expression, the sub-expressions of which are evaluated and auto-printed. NEW FEATURES: * 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(). DEPRECATED AND DEFUNCT: * set.sys.path.jupyter() is defunct and should be replaced with set.jupyter.path(). * fileArgs() is defunct and should be replaced with progArgs(). BUG FIXES: * 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. CHANGES IN this.path 2.3.1 (2023-12-10): BUG FIXES: * 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. CHANGES IN this.path 2.3.0 (2023-12-02): SIGNIFICANT USER-VISIBLE CHANGES: * Previously defunct functions this.path2(), this.dir2(), this.dir3(), and normalized.shFILE() were removed entirely. NEW FEATURES: * this.path() is now compatible with GUI 'Emacs'. CHANGES IN this.path 2.2.0 (2023-10-29): SIGNIFICANT USER-VISIBLE CHANGES: * 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. NEW FEATURES: * this.path() works significantly better with source references. * this.path() is now compatible with '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. CHANGES IN this.path 2.1.0 (2023-09-12): NEW FEATURES: * 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. BUG FIXES: * 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. CHANGES IN this.path 2.0.0 (2023-08-08): SIGNIFICANT USER-VISIBLE CHANGES: * 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 NEW FEATURES: * 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. DEPRECATED AND DEFUNCT: * 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(). BUG FIXES: * Fixed display issues in LaTeX and plain text documentation. * reset.proj() now has environment 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'.
