* lisp/org-latex-preview.el (org-latex-preview--display-info,
org-latex-preview--cleanup-callback, org-create-formula-image-async,
org--make-preview-overlay): Apply a filter to the dvisvgm process in
order to place overlays as images are produced, and along the way
extract size and baseline information that is used to more accurately
position the overlay image. Because `org-latex-preview--place-images'
is now run within a filter and hence the stdout buffer, we need to
record the org buffer and switch to it before placing overlays.
(org-latex-preview--image-extract-async): Record the DPI-based scaling
factor so it can be accounted for when calculating the pt-scale fragment
height/width/depth.
(org-latex-format-options): Introduce a new parameter :zoom for
affecting the display scaling of images with associated height
resolution, but unlike :scale not the resolution/size of the images
files themselves. This is then used in `org--make-preview-overlay'.
* lisp/org-latex-preview.el (org-latex-preview--cleanup-callback,
org-create-formula-image-async, org-create-latex-preview): Instead of
using lists of the same length for fragment information, use a single
list of fragment information plists. This allows for more information
to be stored/used without ending up with half a dozen disparate lists
that we rely on lining up.
* lisp/org-latex-preview.el
(org-latex-preview--cache-image, org-latex-preview--get-cached):
Implement image data save/retrieve functions using org-persist.
(org-place-latex-image, org-create-latex-export,
org-latex-preview--cleanup-callback, org-create-formula-image-async,
org-create-latex-preview, org--make-preview-overlay): Use the new model
of image data caching relying on org-persist.
* lisp/org-latex-preview.el (org-make--preview-overlay): Supplying an
image file when creating a latex preview overlay is now optional.
This change is in preparation for fully-automatic preview generation,
which requires "dummy" overlays to be placed on latex fragments that
have not yet been fully inserted or previewed.
* lisp/org-latex-preview.el (org-preview-latex-process-alist,
org-preview-latex--create-tex-file, org-preview-precompile):
Add a new entry `:latex-precompiler' to
`org-preview-latex-process-alist', and tweak imagemagick-specific
`:image-converter' entries. The function `org-preview-precompile' now
accepts two arguments. Extra processing info is used to find the
right precompilation command.
* lisp/org-macs.el (org-async--execute-callback, org-async-call): Change
the org-async call arguments callback form to start with the symbol
org-async-task. This allows for a list of callbacks to be
differentiated from a single callback. `org-async-call' is also
extended to accept a a callback of this form as its sole argument.
* lisp/org-latex-preview.el (org-latex-preview--image-extract-async,
org-latex-preview--tex-compile-async, org-create-formula-image-async):
Use the new async callback form.
* lisp/org-latex-preview.el (org-place-latex-image,
org-create-formula-image-async, org--make-preview-overlay,
org-latex-preview--dvisvgm-callback): Edit the dvisvgm generated SVGs to
use "currentColor" instead of a hardcoded foreground color. To then set
the color of the displayed images, set the overlay face as appropriate.
(org-create-latex-preview): Now that the foreground is generalised, when
producing the sha1 hash for an SVG image, the current foreground value
should not affect it.
* lisp/org-latex-preview.el (org-create-formula-image-async): When using
dvipng with the "--follow" flag, image processing can occur
concurrently, so we may as well check for this case and start it
concurrently when this occurs.
* lisp/org-latex-preview.el (org-create-preview-string,
org-create-latex-preview, org-latex-replace-fragments,
org-create-formula-image-async): Refactor
`org-create-formula-image-async', specifically by splitting up the
texfile creation, texfile compilation, image extraction, and cleanup
phases into individual functions (`org-preview-latex--create-tex-file',
`org-latex-preview--tex-compile-async',
`org-latex-preview--image-extract-async',
`org-latex-preview--cleanup-callback') and use `org-async-call' for
managing async. Along the way a few other minor tweaks have crept in.
* lisp/org-latex-preview.el (org-create-formula-image-async): Change
how the latex header is computed to account for precompiled headers.
(org-preview-use-precompilation): Boolean to control if
header/preamble precompilation is enabled when generating latex
previews. If enabled, previewing will be much faster at the expense
of a slower first run.
(org-preview-precompile): This function creates precompiled dumps of
latex preambles/headers, and is intended for use with
`org-create-formula-image-async'.
* lisp/org-latex-preview.el (org-preview-latex-process-alist,
org-create-formula-image-async): Change the default latex command to
include the input file name. Previously the input file was introduced
via process input for compatibility with preview.sty directives. But
it appears that it's possible to simply set \RequirePackage{preview}
in the latex header without issues.
* lisp/org-latex-preview.el (org-create-latex-preview): Instead of
getting the face using `face-at-point' use `get-text-property' on the
position one before the start of the LaTeX fragment. This ensures that
the face is that of the parent element rather than the LaTeX fragment.
* lisp/org-latex-preview.el (org-latex-preview-fragments): Collect and
send all fragments to be processed in a single pass.
(org-create-latex-preview): Apply cached previews and send the
other fragments to be generated asynchronously.
(org-create-formula-image-async): Generate latex preview
images asynchronously and apply them to the buffer.
(org-create-preview-string): Helper function that accepts a math
fragment and returns a latex snippet suitable for use with
preview.sty. Respects color preferences.
* lisp/org-latex-preview.el (org-latex-preview-fragments,
org-latex-replace-fragments, org-latex-collect-fragments): Introduce a
new function to collect all LaTeX math fragments in a
region (`org-latex-collect-fragments') and use it in
`org-latex-preview-fragments' and `org-latex-replace-fragments'.
* lisp/org-latex-preview.el (org-create-latex-preview,
org-create-latex-export): Split the export and preview functionality of
`org-create-latex-preview' into two functions: a rewritten
`org-create-latex-preview' that now /only/ deals with previews, and
`org-create-latex-export' for exports.
(org-latex-preview-fragments): Use the new `org-create-latex-preview`.
(org-latex-replace-fragments): Use the new `org-create-latex-export`.
* lisp/org-latex-preview.el (org-format-latex, org-create-latex-preview,
org-latex-replace-fragments): The rather large `org-format-latex'
function mixed the preview and export code paths together in rather
confusing way. This has now been split into
`org-latex-replace-fragments' for export, and
`org-latex-preview-fragments' for in-buffer previews.
(org--latex-preview-region): Replace `org-format-latex' with the more
specific `org-latex-preview-fragments'.
(org-latex-tentative-math-re): Instead of let-binding the math regexp,
use a const and explain its usage.
* lisp/ox-odt.el (org-odt--translate-latex-fragments): Replace
`org-format-latex' with the more specific `org-latex-replace-fragments`.
* lisp/ox-html.el (org-html-format-latex): Replace `org-format-latex'
with the more specific `org-latex-replace-fragments`.
* lisp/org-latex-preview.el (org-create-latex-preview,
org-place-formula-image, org-place-latex-image,
org-place-latex-image-link): Replace `org-place-formula-image' with two
functions, one for overlays (`org-place-latex-image') and another for
links (`org-place-latex-image-link').
* lisp/org-latex-preview.el (org-create-latex-preview,
org-format-latex): Split `org-format-latex' into two, creating a new
function for the `cond' branch that deals with
`org-preview-latex-process-alist'.
* lisp/org.el (org-format-latex-options, org-format-latex-signal-error,
org-latex-to-mathml-jar-file, org-latex-to-mathml-convert-command,
org-latex-to-html-convert-command, org-preview-latex-default-process,
org-preview-latex-process-alist, org-preview-latex-image-directory,
org-format-latex-header, org-format-latex-mathml-available-p,
org--make-preview-overlay, org-clear-latex-preview,
org--latex-preview-region, org-latex-preview, org-format-latex,
org-place-formula-image, org-create-math-formula,
org-format-latex-as-mathml, org-format-latex-as-html,
org--get-display-dpi, org-create-formula-image, org-dvipng-color,
org-dvipng-color-format, org-latex-color, org-latex-color-format,
org-normalize-color): Move to org-latex-preview.el.
* lisp/org-latex-preview.el: A new home for code related to the
generated of in-buffer previews of LaTeX fragments.
