This is interesting. If it needs to open a local file, that suggests the http server is not started. Can you tell me what the output of `print(tools::startDynamicHelp(NA))` (run from within R) is in that situation? The new version of my function (below) may fix this. > On Mac emacs GUI, this function does not work with default settings. > This is the message displayed in in *eww* buffer: > Loading http://127.0.0.1:ting httpd help server ... done > [1] 23824/doc/html/index.html… This is helpful! My original code didn't account for the extra text emitted when the http server is started the first time. The following should fix that: ``` (defun ess-eww () (interactive) (let ((BUF (generate-new-buffer "URL")) (PORT)) (ess-command "print(tools::startDynamicHelp(NA))" BUF) (with-current-buffer BUF (setq PORT (buffer-substring (search-forward-regexp "\\[1\\] ") (point-max))) (message (buffer-substring (point-min) (point-max)))) (kill-buffer BUF) (eww (concat "http://127.0.0.1:"; PORT "/doc/html/index.html")))) ``` This may also fix the problem in the Linux terminal. It works here using terminal Emacs (on Debian). Question for the ESS devs - is there a simpler way to get text from the R process into Elisp? I've used `ess-command`, and then collected the relevant info out of the buffer the result is printed to. This requires a bit of fussing to get to the value I want (via `search-forward-regexp`). That might be brittle. If I could directly transfer the first value of an R vector into an Elisp variable that would be better. - tyler ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/ess-help
