CTAN update: l3kernel

Date: May 8, 2021 8:50:11 PM CEST
The LaTeX Team submitted an update to the l3kernel package. Version: 2021-05-07 License: lppl1.3c Summary description: LaTeX3 programming conventions Announcement text:
## [2021-05-07] ### Added - Color export in comma-separated format - `\ur{...}` escape in `l3regex` to compose regexes - `\seq_set_split_keep_spaces:Nnn` (see #784) - `\seq_set_item:Nnn(TF)` and `\seq_pop_item:NnN(TF)` - `\box_ht_plus_dp:N` (issue #899) - `\clist_map_tokens:nn`, `\clist_map_tokens:Nn`, `\str_map_tokens:nn`, `\str_map_tokens:Nn` ### Changed - Use prevailing catcodes instead of string in regex replacement (issue #621) (*Breaking change*) - `\__kernel_file_name_sanitize:n` now uses a faster `\csname`-based approach to expand the file name - Improved performance for basic conditionals - `\pdf_version_gset:n` support for `dvips` - Improve handling of `\exp_not:n` in `\text_expand:n` (issue #875) - `\file_full_name:n` now avoids calling `\pdffilesize` primitive multiple times on the same file - Show printable characters explicitly in `\regex_show:n` - Regex replacement now errors when using a submatch (`\1` etc) for which the regex has too few groups - Showing complex datatypes now validates their internal structure (issue #884) - Indexing in l3doc: all page references before codeline references, improve target placement, solve pdfTeX and makeindex warnings ### Fixed - Evalutate integer constants only once (issue #861) - Detect `\ior_map_inline:Nn` calls on undefined streams (issue #194) ### Deprecated - `l3docstrip` converted to a stub which simply loads DocStrip: use the latter directly

l3kernel – 3 programming conventions

The l3kernel bundle provides an implementation of the 3 programmers’ interface, as a set of packages that run under . The interface provides the foundation on which the 3 kernel and other future code are built: it is an API for programmers. The packages are set up so that the 3 conventions can be used with regular packages.
