Instead of maintaining a file queue to process for updating the Org-roam
database, we instead simply call `org-roam-db-build-cache` to rebuild
the db. `org-roam-db-build-cache` feels Fast Enough(TM), and basically
runs instantly if no files are modified. This greatly simplifies the
code, basically allowing to maintaining a single code path for db
operations.
This PR should also address the slowness wrt to ID links. Org-roam now
builds the headline information first, so there is no need to read the
file to check if the headline is there. The downside to this is that
this only works for IDs in Org-roam files.
* (fix): org-roam-db-build-cache: fix order of processing
Org-roam used to perform the removal of deleted files towards the end.
This can cause some issues with db rebuilds. Consider this scenario:
1. Create a file `foo.org` with `id:abc`
2. Run `org-roam-db-build-cache`
3. Delete `foo.org`
4. Create a file `bar.org` with `id:abc`
5. Run `org-roam-db-build-cache`
Here Org-roam will complain that the id `abc` is a duplicate, and error
out, because the data for `foo.org` has not yet been cleared from the
database. This PR reorders the db creation steps the following way:
1. Figure out which files no longer exist, and which files are modified
2. Clear the database for these files, leaving only files that are
unmodified in the database
3. Insert new data from modified files into the database
* (fix): use org-roam-link-title-format in link replacement
Makes `org-roam-format-link` respect `org-roam-link-title-format`.
Also removes lowercasing via prefix argument in `org-roam-insert`, not
sure how many people use it.
* update changelog
* (fix): fall back to org-id search ID face computation
Fixes the scenario where the face is reported as invalid although it is
part of Org's ID files (e.g. in the agenda).
Fixes#1191.
This can however slow face computation a lot (when there are many org
id/agenda files). Here, we choose to focus on correctness.
* Document faces, default to only applying to Org-roam notes
Otherwise it breaks `org-roam-db-build-cache` as it relies on temporary buffer.
Without keeping the buffer, `org-roam--extract-links` kills it and any further
functionality of file processing breaks.
Prevent error when trying to move file to same name
Prevent string matching in org from messing with the current re-search-forward
position which has caused infinite broken search
Move the default location of `org-roam.db` to the user's Emacs
directory. This is a more sensible default: those who sync their
Org files would not have the database synced over as well.
Additionally cache IDs at outline-level 0, now that property drawers are supported in Org 9.4.
Update org-roam--format-link to prefer ID links wherever possible. That is, when a file has an ID, use an id link instead of file link.
Adds `org-roam-link-file-path-type`, used for link path computation
wherever sensible. This includes in the org-roam backlinks buffer, and
in link replacement.
Also moves link expansion/fixing from cache build to Org-roam buffer
render time. This reduces cache build time, but makes buffer rendering
slightly slower.
Previously we had overwritten the Org's store link function for files,
to create IDs if the point was under the headline. This has several
issues:
1. It becomes impossible to store a link to the file using `org-store-link`
2. This override is global across Org, although we had a guard in
`org-roam-store-link`
3. IDs are created during an org-capture, because org-capture calls `org-store-link`
This is unnecessary. Org provides `org-id-store-link` instead for this
purpose. Instead, we advice `org-id-new`, to queue the file for a DB
update if an ID was created.
`org-mode` builds the org-agenda-files menu entry for every file
visited. This functionality isn't required and useful when building
the cache in temporary org buffers.
`find-file-noselect` is affected by the user's init.el, and there is
little control over what is being activated. For database updates, read
access is all we need, so we use `with-temp-file`.
This changes ref extraction to parse the ref using the org plain-links
syntax. This works for arbitrary `cite` links, and web links.
Link storage and ref lookup is now based on the path (e.g.
`//google.com`) or `author_year`.
file-truename calls alone accounts for over 20% of CPU samples in org-roam-db-build-cache. It's expensive and unnecessary. To get an absolute path, expand-file-name alone is enough.

PR #1076 prevented the title change hook from causing errors for new files,
but completely disables the behaviour. To cause the title hooks to take
effect, we set the local variable `org-roam-current-title` upon save,
regardless of whether the hook ran.
This should have the effect of enabling the title change behaviour upon
first save, assuming the save succeeds.
