# officer 0.7.5

## Word

- drop deprecated `seqfield` argument in `run_word_field()` and remove `run_seqfield()`
(old duplicate of `run_word_field()`) .

## RTF

- RTF sections were debugged and now behave correctly: page orientation,
columns, margins and per-section headers / footers all apply as expected,
including multi-column layouts (#726, thanks to Nathan Kosiba).

- New paragraph style API for RTF, aligned with `docx_set_paragraph_style()`
on the Word side. `rtf_set_paragraph_style()` is now exported and takes
`style_id`, `style_name`, `base_on`, `fp_p`, `fp_t` and `outline_level`;
`rtf_styles_info()` returns the document's style table. `rtf_add()` accepts
a `style` argument so paragraphs (character, factor, double, fpar,
block_list) can reference a named style. `rtf_doc()` registers built-in
`"heading 1"` / `"heading 2"` / `"heading 3"` styles with `\outlinelevel`
values, so styled paragraphs feed Word's navigation pane and TOC field.
Use `rtf_set_paragraph_style()` after `rtf_doc()` to override a built-in
style; the row keyed by `style_id` is updated in place.

- `rtf_add()` now accepts [block_toc()] objects and emits a TOC field
in the RTF stream, in parity with `body_add_toc()` for Word. Word
populates the table at open time using the outline levels carried by
the built-in heading styles; LibreOffice does not render the TOC
automatically.

## Excel features

- Images and ggplot drawings placed on Excel sheets with
`sheet_add_drawing()` can now be anchored to cells. Pass
`anchor = "B2:H20"` (a cell range) to make the drawing move and
size with cells, Excel's default behaviour. Pass `anchor = "B2"`
(a single cell) to make it move but keep its own size. Omit
`anchor` for the previous fixed-position layout. The `edit_as`
argument controls what happens when rows or columns are resized.
The same options are available to charts inserted via 'mschart'.
- Excel sheets can host the chartEx chart family (boxplot, funnel,
histogram, pareto, sunburst, treemap, waterfall) in addition to the
classic chart types. The new helper `ooxml_chart_uris()` returns the
identifiers needed by `xlsx_drawing` to wire either family.
- Two new building blocks for packages that emit OOXML directly
(such as 'mschart'): `solid_fill(color)` returns a DrawingML
solid-fill fragment with optional alpha; `to_pml()` now has an
`sp_line` method exposing line-properties conversion that was
previously internal.

# officer 0.7.4

## Features

### Excel

- new functions `sheet_write_data()` and `sheet_add_drawing()` for writing
data and inserting drawings (charts, vector graphics) into xlsx workbooks.
`sheet_write_data()` is an S3 generic: beside `data.frame`, it also accepts
a `character` vector (one cell per element, vertical by default; 
`direction = "horizontal"` for a row), an [`fpar()`] (richtext inline cell honouring
bold, italic, underline, strikethrough, size, colour, font, sub/superscript)
and a [`block_list()`] (one cell per `fpar` item, stacked).
`sheet_add_drawing()` has an `external_img` method and a `gg` method.
- new function `sheet_remove()` to delete a sheet from an xlsx workbook.
`add_sheet()` is purely additive and never drops any sheet; call
`sheet_remove()` explicitly if the template's default sheet is not wanted.

### Word

- `write_docx_settings()` now preserves the existing `settings.xml`
content instead of rebuilding it from scratch. This fixes the loss of
embedded font settings, math properties, footnote/endnote settings and 
other XML elements during docx roundtrips (#554).
- new function `docx_embed_font()` to embed TrueType or OpenType font
files into Word documents. Embedded fonts ensure correct rendering on
systems where the font is not installed (#554).

### Word & PowerPoint

- new functions `list_item()`, `block_list_items()` and
`body_add_list()` to create bullet or numbered lists with rich text
(`fpar`) and multi-level nesting. Works in both Word and PowerPoint
documents (#314).

### Formatting properties

- `fp_par()` and `fp_par_lite()` gain `first_line` and `hanging`
arguments to control paragraph first-line and hanging indents (in
points). Honored by the Word, PowerPoint, HTML and RTF renderers.
`hanging` wins when both are provided (flextable #704).

## Issues

- `sheet_select()` now deselects other sheets, fixing the issue where
multiple tabs appeared selected when opening the workbook.

# officer 0.7.3

## Features

- function `remove_slide()` now supports deletion of multiple slides
thanks to Wahiduzzaman Khan (#691).
- add `cursor_reach_index()` to set the cursor at a specific index position in
the document (#574).
- `set_doc_properties()` gains a new argument `hyperlink_base` to set the base
URL for relative hyperlinks in Word documents. `doc_properties()` now returns
the `HyperlinkBase` property when available (#630).

## Issues

- fix feed_from_xml for 'officedown'.
- `remove_field` argument of function `docx_summary()` now work as expected.
- also remove relationships in `sanitize_images()` (#708).
- Package now supports read-only installations (e.g., when installed as root or 
via Nix). Previously, attempting to create presentations would fail with 
permission errors in read-only environments (#706).

## Changes

- Defunct function `docx_reference_img()`.

# officer 0.7.2

## Issues

- RTF support strike text setting.
- fix an issue with bookmark selections in `docx_summary()`.
- fix `fp_par_lite()` management of argument `tabs`.
- there was a regression with svg in docx, it is solved now.

## Features

- new internal utilities `base64_to_image()`, `as_base64()`, `from_base64()` 
and `plot_in_png()`.


# officer 0.7.1

## Features

- new function `floating_external_img()` to add a floating image in a 'Word' 
document.

## Changes

- Refactoring of `docx_summary()`: the function now provide more run-level 
information (text formatting, images, hyperlinks, bookmarks). 
- Refactoring of `sanitize_images()`: the function now works as expected. It will
be unexported soon since it is now automatically called before writing documents
and is therefore no longer useful to end users.
- Remove defunct `slip_in*` functions.

## Issues

- Fix RTF sections that were sometimes invisible
- issue with image in google docs should now be fixed (#689)
- add automatically namespaces when calling `write_elements_to_context()`
- Fix lists styles with `body_import_docx()` thanks to Sean Anderson.

# officer 0.7.0

## Features

- new function `docx_set_settings()` to set document settings of a Word document.
This function can be used to specify if the document should handle odd and even headers and footers,
to change the list separator, etc.
- new function `body_import_docx()` to import content from an external Word document.
- `fp_text()` now supports `strike` argument to set strikethrough text.
- `ph_with()` now handles `Date` objects without prior conversion to character. 
  The date format can be set locally via the `date_format` arg or globally via 
  `options(officer.date_format = ...)` (#683)

## Issues

- Fix Rmd output with paragraphs `fpar()` so that no stylename is used.
- Improve `set_doc_properties()` error and warning messages.
- `page_size()` now manage correctly sizes if `orient = "landscape"` and not 
`unit = "in"`.
- `phs_with()` and `add_slide()` now have a more informative error message if 
the ph label is unknown (#672)
- Function `set_doc_properties()` now supports NULL and NA custom properties in 
a Word document.
- argument `separator` is not used anymore in `block_toc`. Now the Word field is 
generated with no separator making it more portable over the different locales 
Word users could have.

# officer 0.6.10

## Issues

- Fix RTF generation so that `fp_par_lite()` works also for RTF output.
- Fix `doc_summary(... detailed=TRUE)` when the runs has a shading (w:shd) with 
a fill but no color attribute.
- `plot_layout_properties()`: new `slide_idx` arg to specify which slide's layout 
  to plot. The plot title now also contains the master's name (#666)

# officer 0.6.9

## Features

- New functions `body_append_start_context()`, `write_elements_to_context()` and 
  `body_append_stop_context()` to append elements at the end of a Word document
  in a faster way. This is useful when the document is large and the user wants to
  only append elements at the end of the document. 
- New function `block_gg()` to add a ggplot object to a Word document. It is 
  handy when the user wants to add a ggplot object to a Word document with 
  new function `write_elements_to_context()`.
- New function `fp_par_lite()` to create a paragraph formatting object with only the 
  properties that are needed. It is useful when the user wants to create a 
  paragraph object with only the properties that are needed and not all the 
  properties. It can also be used to create a paragraph formatting object 
  that reuse a style but with some modifications.
- Function `print.rdocx()` gains new arguments `copy_header_refs` and 
  `copy_footer_refs` to copy header and footer references from the
  default section to other sections. This should be useful when the user
  wants to add sections but also propagate the header and footer references.
  

## Performances

- Refactored `body_add.block_list()` to speed up the process of adding a block 
  list to a Word document, optimization of the process is made by minimizing call 
  to `docx_current_block_xml()`.
- `print.rdocx()` execution time improvements.

## Issues

- `add_slide()`: It now suffices to specify a unique `layout`. The `master` will be inferred automatically.  
  Also, the default values for the `layout` (`"Title and Content"`) and `master` (`"Office Theme"`) arg were removed. 
  They only applied to the default pptx template used by `read_pptx()`. To avoid breaking changes in old code, 
  `add_slide()` now throws a deprecation warning, if no layout is specified (either via the `layout` arg or by setting 
  a default layout). It then uses the `layout` arg's former default value (`"Title and Content"`). This makes sure, 
  that the behavior of `add_slide()` does not change and avoids backward compatibility issues (#635)
- `layout_default()` sets a default layout for `add_slide()` (#635).
- `print.rpptx` now uses pluralization and marks the default layout (if set by `layout_default()`) with an asterisk (#635)
- Fixed `docx_summary()` when a text run is associated with a text style and 
  when paragraph or text styles are not registered in the Word document style 
  table (thanks to Kaspar Meili).
- `plot_layout_properties()` now takes `cex` as a vector or a list and matches by position, name or partial name. 
  Zero values now hide the text. A single value now applies to all three cex parameters (label, type, and id) (#645)
- `plot_layout_properties()` now shows the default layout, if one is set and there are not slides yet (#645)
- Default page size is now set to exact A4 format for Word documents: `11906 / 1440` and `16838 / 1440` 
instead of `21 / 2.54` and `29.7 / 2.54`.

## Changes

- Deprecate function `docx_reference_img()` as it is no longer useful..

# officer 0.6.8

## Issues

- Simplified input format for `location` arg in `ph_with_*` functions (#623). Instead of a `location` object 
  created by the `ph_location_*` function family, `ph_with_*` functions now resolves certain short form
  input into corresponding `location` objects. For example, instead of using `ph_location_label("<label>")`
  you can now simply pass the `"<label>"` to the `location` arg. The functionn will convert the string into
  the corresponding location object automatically. Other examples are `"body [1]"` for 
  `ph_location_type(type = "body", type_idx = 1)`, or the integer `1` for `ph_location_id(id = 1)`
- Add `slide_visible()` to get and set the visibility of slides (#622).
- debug selector for `ph_remove()` (see #625) that was not working for rvg outputs.
- `phs_with`: filling multiple placeholders on one or more slides at once using key-value pair syntax (#639).
- `add_slide`: new args `...` and `.dots`, both passed to `phs_with` to create slide and fill placeholders in one step (#639).
- add support for pdf in office extensions (#613).

## Internals

- remove old visual tests

# officer 0.6.7

## Issues

- store paddings as numeric values and not integer values.
- remove_fields in `docx_summary()` now also removes "w:fldData" nodes.
- complete the manual of `body_add_docx()` with a note about the file basename
that can not contain ' ' and trigger an error if it contains a ' '. 
- `plot_layout_properties()` gains a 'title' parameter, which will add the layout name as the plot title. Defaults to 
`FALSE`, to not alter the old behavior. Also, the slide width and height are now correctly displayed in the plot. 
Before, a box was drawn around the plot area. However, the plot area var with device size, not slide size.
- class `dir_collection`: Files are now added to a container in the order of their trailing numeric index (#596).
For example, `slideLayout2.xml` will now preceed `slideLayout10.xml`. Before, alphabetical sorting was used, where 
`slideLayout10.xml` comes before `slideLayout2.xml`.
- `layout_properties()` now returns all placeholders in case of multiple master (#597). Also, the internal `xfrmize()` 
now sorts the resulting data by placeholder position. This yields an intuitive order, with placeholders sorted from 
top to bottom and left to right.
- `ph_location_type()` now throws an error if the `id` for a `type` is out of range (#602) and a more 
informative error message if the type is not present in layout (#601).
- `plot_layout_properties()` assignment order fixed for `labels= FALSE` (#604)
- `layout_properties()` gains a `type_idx` column to index phs of the same type on a layout. Indexing is performed based on ph position, following a top-to-bottom, left-to-right order (#606).
- `plot_layout_properties()` plots more information by default now: layout name, ph label, ph id, ph type + index by default (#606).
- `ph_location_type()`: new `type_idx` arg replaces the deprecated `id` arg (#606).
- Add `ph_location_id()` as a new member to the `ph_location_*` family. It references a placeholder via its unique id (#606).
- `plot_layout_properties()`: Now accepts the layout index (see `layout_summary()`) as an alternative to the layout name.
  Gains an argument `legend` to add a legend to the plot. Also prints the current slide's layout by 
  default now, if not layout name is provided explicitly (#595).
  
## Features

- `layout_rename_ph_labels()` to rename ph labels (#610).
- add `layout_dedupe_ph_labels()` to handle duplicate placeholder labels (#589). 
By default, it will only detect duplicate labels, but apply no changes. With 
`action = "rename"`, it auto-renames duplicate labels and `action = "delete"` 
deletes duplicates, only keeping their first occurrence.
- new convenience functions `body_replace_gg_at_bkm()` and `body_replace_plot_at_bkm()`
to replace text content enclosed in a bookmark with a ggplot or a base plot.
- add `unit` (in, cm, mm) argument in function `page_size()`.

# officer 0.6.6

## Issues

- Fix. `docx_summary` preserves non-breaking hyphens. Non-breaking hyphens are 
replaced with a hyphen-minus (Unicode character 002D). Closes #573.
- `docx_summary()` gains parameter 'detailed' which allows to get a detailed 
summary including formatting properties of runs in a paragraph. Formatting 
properties are stored in a list column `run`, where each element 
is a dataframe with rows corresponding to a single 
run and columns containing the information on formatting properties.
- Fix. Add alt text to ggplot's added to a pptx with ph_with.gg. Closes #556.
- embedded image in PPT can now be associated with an hyperlink
- add a check to `block_pour_docx()` to avoid working with file paths 
containing '&'.

## Features

- add coverage to rtf, contributions from Davide Garolini at roche.
- `cursor_reach()` gains new argument `fixed` to enable exact matching.
It defaults to FALSE for backward compatibility.
- `remove_slide()` gains new argument `rm_images` to enable images deletion
from ppt/media.
- new function `body_comment()` adds a comment on an existing paragraph 
at the cursor position.
- `docx_summary()` gains parameter 'remove_field' to prevent field codes 
from appearing in the returned data.frame. 

# officer 0.6.5

## Features 

- new function `fp_tabs()` to enable tabulation marks settings 
with flextable (for Word and RTF).

## Issues

- let the package be used with R < 4 by not using `\(x)` syntax

# officer 0.6.4

## Features 

- `fp_border()` gains support for all line border styles listed in ECMA-376 
  section 17.18.2 and allowed CSS border styles. Closes #165 and #443.

## Changes

- the dataframe returned by `docx_comments()` gains a list column `para_id` containing 
the id(s) of the parent paragraph(s). A possible breaking change is that the `commented_text` 
is now returned as a list column to account for comments spanning multiple runs.
The docs gain a description of the columns of the returned dataframe.
- `opts_current_table()` now ignore 'Quarto' setting.

## Issues

- Fix. Refactor `docx_comments()` to (properly) account for comments spanning 
multiple paragraphs, multiple comments in the same paragraph and replies. Closes #541.
- Check and stop if `fp_text_lite()` is using a *shading.color* but no *color*.
- Check used style in `body_add_caption()`.
- fix `ph_remove()`, `ph_slidelink()` and `ph_hyperlink()` that were not working since
the latest refactoring.
- Use fake attribute `stlname` if available in `docx_summary()`.
- calls to `file.copy(from = "template/*.xml")` are now done with argument 
`copy.mode = FALSE` for compatibility with 'nix'.

# officer 0.6.3

## Features

- new function `run_comment()` to create a run with a comment.
- new function `docx_comments()` to read comments in a Word document as a data.frame.
- Add pptx support for invalid pptx files downloaded from https://slides.new.

## Issues

- Internal function `is_doc_open()` replaces `is_office_doc_edited()` to check if a document is open on Windows. This solves the issue where RStudio crashed while trying to write to an open Office document.
- Add option `preserve` to preserve cell line breaks to `docx_summary()`.
- fix `ph_hyperlink()` when several hyperlinks are inside one slide and refactored `ph_remove()`.

# officer 0.6.2

## Issues

- encode char to rtf from 128 instead of 256
- force 'firstLineChars' to 0 so that Chinese users don't get 
unwanted first indentation.
- avoid segfaults with SVG images by using the function `image_read_svg()`
when source is SVG in `external_img()`.

# officer 0.6.1

## Features

- add support for flextable in `block_list()`.
- add RTF support for `run_autonum()` and `run_reference()`, 
this enables captions support for flextable.

## Changes

any fonts.
- defunct `slip_in_footnote()`.

## Issues

- fix for `to_wml.block_caption()`

this allow to depend on a reference doc (now `convert_custom_styles_in_wml()`).

# officer 0.5.2

## Features

- if magick is available and argument `guess_size=TRUE`, image 
size is read and do not need to be provided.

## Issues

- fix images and links in sections headers and footer.
- fix `body_add()` content order.
- fix issue with properties in 'Office' documents.
- check arguments of `run_autonum()` and add tests.
- update only officer sections

## Internals

- remove `$get_at_cursor()`

# officer 0.5.1

## Issues

- manage also even/first/default sections not defined with officer (indicate 
there is even/first/default parts).
- fix behavior regression with headers and footers replace_text_at_bkm. 
The previous behavior "don't trigger an error if a bookmark is missing" 
is back. 
- force Word default continuous section if no type is specified and first 
page footer/header if it is seen.
- drop "Compatibility Mode" from Word documents.

## Changes

- Change license to MIT.
- drop internal `get_at_cursor()`
- use images sha1 value for filename with package 'openssl'. This should fix 
issues with duplicated images basenames, or non utf names, etc.

## Features

a match in the document.
- add function `docx_current_block_xml()` to let developpers access 
the xml content where the cursor is.  
- `ph_with.xml_document` now manages images paths in slide and 
treats them in the relevant documents.

## Issues

- close 'Slide Master View' automatically.
- more careful reading of document properties
- fix cursor behavior, when `pos='before'`, cursor 
is now set on element added 'before'. Internals about 
cursors have been refactored.

## Changes

# officer 0.4.4

## New features

- `fp_par()` now have argument `word_style`
- add support for `ln` for `external_img` provided by Angus Moore

These values can be used as alternative text for Word tables. These values 
can also be set as "knitr" chunk options.

## Issues

- fix for `is_office_doc_edited()` provided by Andrew Tungate.
- `tab.lp` is no more set to null with usual rmarkdown outputs
- autofit was never used when outputting prop_table to xml

## Changes

- Function `opts_current_table()` read some Quarto values related to 
captions in order to reuse them later.

# officer 0.4.3

## New features

* `set_doc_properties()` now supports any character property. 
It provides an easy way to insert arbitrary fields. Given the challenges 
that can be encountered with find-and-replace in word with officer, the 
use of document fields and quick text fields provides a much more robust 
approach to automatic document generation from R.
* Adding support for fields (e.g. auto slide number) in Powerpoint (#429), 
see `empty_content()`.
* add functionality to set shape geometry and outline, 
see `ph_location(geam=...)`.

for each properties - if a value is not provided, its attribute will 
not be written and as a result, the default properties will be applied. 
Function `fp_text()` has also been adapted, it now supports NA meaning 
to not write the attributes as in `fp_text_lite()`.
