The goal of contextFind is to help developers find
relevant parts of their code, especially helpful when code expands
beyond a single file, such as with Shiny applications.
The package includes an addin to bind contextFind() to a
hotkey (e.g., Ctrl+Shift+F). This opens a mini shiny application with
inputs for the search string, the directory, whether to search
subdiretories, and how many lines of context to print before and after
the found search string:
Clicking the contextFind button prints the results to the console.
For each result (match), contextFind() provides a clickable
labelled link indicating the file and line number of the result,
followed by contextLines=2 lines before and after the
occurrence, with the found string highlighted in yellow. The results are
ordered with most recently modified files at the bottom of the list for
ease of reading in the console.
You can install the latest version of contextFind from
GitHub with:
devtools::install_github("s87jackson/contextFind")or the CRAN stable release with:
install.packages("contextFind")After installing contextFind, restart RStudio, then set contextFind to a hotkey by selecting Tools >> Modify Keyboard Shortcuts:
Now typing Ctrl+Shift+F opens the gadget to perform the search. If text is higlighted when you type the hotkey, it will be passed to the gadget automatically. In the example below, we search for the string ‘selected’ and see the results:
