I=E2=80=99ve been going through org-id rece= ntly. The following issues came up that I would appreciate feedback on: 1. org-id is not loaded by default; it is supposed to be selected by the user (see footnote 2 of (info "(org) Handling links")). Yet, other org libraries rely on it, without requiring it (e.g. ox-icalendar). Also, at least one library (org-bibtex) reimplements bits of org-id=E2= =80=99s internals to avoid requiring it explicitly. Is there a good reason not to make org-id a core library, that is to require it unconditionally from org.el? 2. I would like to deprecate the org-id-method variable. This allows choosing different methods of generating random IDs. But one method is as good as another (they are random*...), so we can just always use a single method (powered by the elisp =E2=80=98random=E2=80=99 function)= . Choosing this allows deprecating several other variables and functions, along with a soft dependency on the external uuidgen binary. Any objections to this course of action? (* Not all the values of org-id-method lead to IDs that are random in the statistical sense. But they are not meaningful from the user=E2=80=99s point of view in any case.) 3. I would like to change the API of the org-id-get function. The current signature is (&optional pom create prefix). POM (i.e. position or marker) is a useless argument, because in the (relatively uncommon) case that callers are interested in a location other than (point) they can wrap the call in (org-with-point-at ...). PREFIX is similarly useless (and in fact unused in org=E2=80=99s code ba= se) because a caller could let-bind org-id-prefix around the call. The new signature would be (&optional create reset), which are both boolean arguments. The question arises of how to make this change. Options I see: a. Hard breakage; code using the old calling convention will break. b. Introduce a new function under a new name, deprecate the old name c. Try to detect which calling convention is in use. Options (a) and (b) have drawbacks. I would like to implement (c) by requiring the create and reset arguments, if given, to have values 'create and 'reset respectively. The old and new calling conventions have identical semantics when both arguments are nil, so that case is not a problem. With the new code, any other value for these arguments (besides nil and a same-named symbol) would indicate use of the old convention, and signal an error. Comments? 4. A similar issue arises for org-id-find. I would like it to always return a marker, rather than having an argument switch between a marker and a cons of filename and position. (There are functions which return the filename or position individually, so returning both as a cons is useless from an API point of view). There=E2=80=99s no goo= d way to detect the old calling convention, however, so I think I have to introduce a new name. (My draft patch is written instead with hard breakage, but stability of API is important so I will change that...) There are other deprecations and renamings as well, but none of them should break third-party code. The resultant patch shrinks the codebase by 60-ish lines and eliminates 3 defcustoms...baby steps. A draft patch is attached to this message; I expect to make further changes based on feedback I receive, so detailed code review (while certainly always appreciated!) can be postponed until the conceptual issues are resolved.
