./devel/tex-l3experimental, Experimental LaTeX3 concepts

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 2019, Package name: tex-l3experimental-2019, Maintainer: pkgsrc-users

The l3experimental packages are a collection of experimental
implementations for aspects of the LaTeX3 kernel, dealing with
higher-level ideas such as the Designer Interface. Some of them
work as stand alone packages, providing new functionality, and
can be used on top of LaTeX2e with no changes to the existing
kernel. The present release includes: xgalley, which controls
boxes receiving text for typesetting. l3regex: kernel support
for regular expression search and replace operations; l3sort:
kernel support for sorting sequences, token lists or comma-
lists, according to user-specified comparison criteria; l3str:
kernel support for string manipulation; l3tl-build: kernel
support for token list building; l3tl_analysis: kernel support
for token list analysis; and xcoffins, which allows the
alignment of boxes using a series of 'handle' positions,
supplementing the simple TeX reference point. All the files of
the bundle are also available in the Subversion (SVN)
repository of the LaTeX3 Project. The bundle on CTAN is based
on a snapshot of the SVN repository on 2013-10-11.

tex-l3kernel{,-doc},tex-l3experimental: update to 2018.49853

## [2019-01-28]

### Added

- Global versions of box affine functions, e.g. `\box_grotate:Nn`
- Global versions of box size adjustment functions
- `\box_(g)set_eq_drop:NN`, `\(h|v)box_unpack_drop:N`
- `\file_get:nnN` and `\file_get:nnNTF`
- Experimental functions `\sys_shell_get:nnN` and `\sys_shell_get:nnNTF`

### Changed

- `\char_generate:nn` now always takes exactly two expansions
- Move `\prg_generate_conditional_variant:Nnn` to stable
- Renamed experimental `\box_trim:Nnnnn` and `\box_viewport:Nnnnn` as
  `\box_set_trim:Nnnnn` and `\box_set_viewport:Nnnnn`, respectively

### Deprecated

- `\box_(g)set_eq_clear:NN`, replaced by `\box_(g)set_eq_drop:NN`
- `\(h|v)box_unpack_clear:N`, replaced by `\(h|v)box_unpack_drop:N
- `\tl_(g)set_from_file(_x):Nnn`, replaced by `\file_get:nnN`

### Fixed

- Scope treatment of `\box_set_dp:N`, _etc._
- In (u)platex: detection of spaces in `\tl_rescan:nn` and related
  functions

### Removed

- Experimental function family `\tl_(g)set_from_shell:(N|c)nn`
  (replaced by `\sys_shell_get:nnN`)

tex-l3experimental: update to 2018

Release 2017-12-05

 - Fix loading of l3str-format

 - Fix handling of \iow_newline: in \iow_wrap:nnnN

 - \cs_generate_variant:Nn now warns on incorrect variant
   relationships

 - Better recovery by \dim_set:Nn, etc., if passed
   skip expressions

 - Better handling of global/local consistency in variable
   setting

 - String mappings now include space characters

 - Revise l3doc to no longer require "[aux]" (deprecated) or
   "[int]" in code mark up: "[int]" is retained for cases where
   auto-detection of internals is not possible

 - Deprecate \token_new:Nn

 - Documentation improvements

Log message:
tex-l3{kernel,packages,experimental}{,-doc}: update to 2017.45340

- Rename \box_use_clear:N to \box_use_drop:N as this command has
  non-standard grouping behaviour
- New \inteval command in xfp
- New \c_catcode_active_space_tl
- Fix bug with color code when \current at color is not a simple
  string
- Fix behaviour of \sys_rand_seed: in engines without the
  underlying random number primitives
- Allow only integer powers for negative bases in floating point
  expressions
- Various documentation improvements

Update tex-l3{experimental,kernel,packages}{,-doc} to 2017.44864

 - New \hbox_set_to_wd:Nnw and \vbox_set_to_ht:Nnw functions
 - Revised l3file module to give better defined
   path/file/extension split
 - New experimental functions in l3file: \file_input_stop:,
   \file_get_mdfive_hash:nN, \file_get_size:nN and
   \file_get_timestamp:nN; currently XeTeX does not support
   getting file size/timestamp
 - New experimental \mode_leave_vertical: as a code-level
   equivalent of \leavevmode
 - New experimental support for shell escape in l3sys module
 - New mechanism for checking variable declarations locally:
   see option "enable-debug" and
   \debug_check_declarations_(on|off):
 - More invalid regex patterns trapped with warning
 - More regex documentation examples
 - Bug fix for \tl_mixed_case:n(n) with pdfTeX when the first
   character is outside the ASCII range
 - Fix nesting of selective setting in l3keys
