I extremely would like to put the line numbers down along with my notes. Although there is a way to store a link for text search for the current line, I haven't found a way to create a link to a line number in the current buffer. Is there anyway to do that?

Thanks > > > > Take a look at org-capture: http://orgmode.org/manual/Capture.html *Following* a link with a line number is no problem: org does that out of the box with a link like [[file:foo.txt::NNN][desc]] That is actually documented: (info "(org) External links") The problem is to make sure org-store-link will actually store the line number (along with everything else) so that then org-insert-link can insert the link in the proper format. I don't think there is a function to do that out of the box for line numbers, but you can easily (for some value of "easily") write your own. Look in (info "(org)Adding hyperlink types") for some hints. Briefly, you write a function that checks whether it wants to deal with the link or not, and you add it to org-store-link-functions. I don't have the time to try it out right now, but I believe this should work for what you want. Nick ^ permalink raw reply [flat|nested] 11+ messages in thread

It works, though it works only to the specified file(s) by overruling the original org-store-link-functions. Ideally, it would be great if in the normal stored org link, line number could be included in the link and would be ripped off from the text to search the linked file.

Yes, org marches down the link handlers and takes the first positive response as the answer. You can make the function arbitrarily complicated of course, if you don't like the behavior, but in any case, it will have to say "yes" (and provide the link in some format) or "no" - in the latter case, org will continue on with the rest of the functions in the list (and fall back to its default if *no* function says "yes"). > Ideally, it would > be great if in the normal stored org link, line number could be > included in the link and would be ripped off from the text to search > the linked file. > I'm confused - what exactly are you asking for here?

I meant to create a link like [[file:foo.txt::123 whatever_text]], when users open the link, org-mode searches "whatever_text"; if it doesn't find anything, jump to the line 123. The idea behind that is that it is possible the line is changed and is unsearchable but still remains in the same line number. This, however, is probably an issue of built-in org-mode design, beyond the scope of user customization.

The idea behind that is that it is possible the line > is changed and is unsearchable but still remains in the same line > number. I guess the main idea is that it is more likely for the text around the link to remain the same: the line number can change (e.g. if you add stuff at the beginning of the file), but the surrounding text will probably remain the same, so a context search is more likely to find you what you want. But you are right in that a line number can sometimes disambiguate things, e.g. the etags functionality in emacs works (worked? not sure if the implementation is still the same) by using a position to go to and then searching in ever-widening circles around that position in order to find the appropriate context. That way, identical contexts could be used (a necessity for etags) and still be distinguished from each other. > This, however, is probably an issue of built-in org-mode > design, beyond the scope of user customization. > Yup.
