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:
