This used to work!
I suspect a bug in Idris itself, where it's likely sending the source locations after post processing to get rid of the tracks.
I'm away from the computer on parental leave, but if someone wants to work on this, check the highlight commands being sent by Idris.

Is there a way to get the same highlighting on .idr files and .lidr files? Thanks + cheers, Nicola

Thanks David, I have opened https://github.com/idris-lang/Idris-dev/issues/4799#issue-543469766. Best, Nicola
As reported in https://github.com/idris-lang/Idris-dev/issues/4799#issuecomment-569899621, there seem to be two problems in the current idris-mode.
For syntax highlighting to work as expected for .lidr files, the function
(defun idris-highlight-column (idris-col)
"Compute the Emacs position offset of the Idris column IDRIS-COL, for highlighting.
In particular, this takes bird tracks into account in literate Idris."
(+ idris-col (if (idris-lidr-p) 1 -1)))
had to be modified as suggested by andrewmcveigh in idris-hackers/idris-mode#480 as
(defun idris-highlight-column (idris-col)
"Compute the Emacs position offset of the Idris column IDRIS-COL, for highlighting.
In particular, this takes bird tracks into account in literate Idris."
(+ idris-col (if (idris-lidr-p) -1 -1)))
and loaded. The second problem is that the file that defines idris-highlight-column
, idris-highlight-input.el
, is not loaded when idris-mode is started. Thus, just modifying the function has no effect when idris-mode is loaded in a fresh emacs instance. One has to manually load idris-highlight-input.el
for syntax highlighting to work as expected. Cheers, Nicola
