The existing text and extratext options are retained as aliases. - The position of the whitespace guards for EAN/UPC symbols was simplified and better aligned with the text. - The position of the whitespace guards for standalone EAN/UPC addons was fixed. - The text{x,y}align=justify options were fixed for the linear and matrix renderers. - The text processing for the Code 39 Extended and Code 93 Extended encoders was fixed. - The text renderer now centres each character using stringwidth and pathbbox for font-independent alignment in the direct text positioning path. - Text offsets were adjusted for EAN/UPC-based symbologies and addons to account for ink-centre anchoring. Non-EAN encoders with per-character text placement were converted to use centre-aligned single string rendering. - FMLY was added to the encoder metadata. - The C API and SWIG bindings were expanded with support for lazy loading of resource bodies. - Input validation was hardened across all encoders, including data length checks, empty data rejection, and implementation limit guards for large allocations. - The renderers now validate their input structures and the text renderer handles single-character justify alignment correctly. - All resources now clean up the dictionary stack when an error is raised, preventing dict stack leaks in caller contexts. - Renderer error handling was improved: correct graphics state restoration, operand stack cleanup for invalid colors, and redundant gsave/grestore removal from composite rendering paths. - Raw mode input validation was improved for Code 128, Code 16K, Data Matrix, PosiCode, Ultracode, PDF417 and Micro PDF417, including ^NNN format and codeword range checks. - Data exceeding the maximum symbol capacity is now rejected during encoding for QR Code, Data Matrix, Code One, PDF417 and JAB Code. - Codablock F, Code 16K and the matrix renderer now handle large symbols without overflowing the operand stack. - GS1 input validation was improved for DataBar Expanded, DataBar Stacked Omnidirectional, GS1 Composite Component and GS1 North American Coupon. - JAB Code now validates eclevel, mask, colors, rows and columns options. PRNG constants now avoid integer literals exceeding the signed 32-bit range. - PDF417 and Micro PDF417: Fixed text submode optimizer crash with long all-text inputs by increasing the sentinel value used in the Viterbi cost comparison. - JAB Code: Fixed crash in slave symbol mode where metadata encoding referenced an undefined variable. - The AusPost encoder now supports FCC 87 (Routing) and FCC 92 (Redirection) barcodes. - The renderers now support a `default_inkspread` global context setting. - The GS1 AI linter was realigned with the latest release of the GS1 Syntax Dictionary. - User option validation was improved for the Codablock F, Code 16K, Code 49, Micro PDF417 and PDF417 encoders. - User option validation was improved for the linear, matrix and maximatrix renderers. - The encoder for DotCode was fixed to ensure a minimum symbol dimension when the opposite dimension is large. - The performance of the PDF417, Micro PDF417, Code One, OneCode, Data Matrix and GS1 Composite Component encoders was improved. - The time to generate error correction polynomials was improved using a FIFO cache for the QR Code, Data Matrix, PDF47, Micro PDF417, MaxiCode, Dot Code, Han Xin and Ultracode symbologies. - The performance of the Code 128, Codablock F, Posicode and Code 16K encoders was improved. - Stack leaks during error handling were fixed for the Data Matrix, PDF417, Micro PDF417, ISBN, ISMN, AusPost and Telepen symbologies. - The performance of generating the error correction codewords for AusPost symbols was improved. - Several stack leaks were fixed for GS1 AI and DL data processing. - The debug and dontdraw options of all encoders must now be enabled using a pair of global switches. - The performance of generating the error correction codewords for Aztec Code, Han Xin Code, QR Code, Data Matrix, Code One, Maxicode, PDF417, Micro PDF417, Ultracode symbols was improved. - The Ultracode encoder was fixed so that colours are correctly selected for rendering. - The performance of the matrix renderer was further improved. - Common colour handling code was factored out of the renderers into its own resource. - The performance of the matrix renderer was significantly improved. - The QR Code encoder performance was enhanced by precalculating the mask function patterns and applying them simultaneously to the data bitstream. - A mechanism to "preload" the lazy variables via global context was added. - Switch from loadctx/unloadctx mechanism to a more direct method of preloading static state, with lazy initialisation. - The Two-Track Pharmacode encoder's text positioning was fixed. - The USPS Intelligent Mail encoder's text positioning was fixed. - Common text rendering code was factored out of the linear and matrix renderers into its own resource. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/graphics/pstricks/contrib/pst-barcode More information is at https://ctan.org/pkg/pst-barcode -------------------------------------------------------------------------------- Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 13 May '26

13 May '26

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-05-12 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: -------------------------------------------------------------------------------- ## expltools 2026-05-12 ### explcheck v0.21.0 #### New features This version of explcheck has implemented the following new features: - Add command-line option `--inline-config`. (suggested by @muzimuzhi in #203, added in #211) This option accepts a TOML string that is treated as a config file, overriding any options specified in config files. The option may be specified repeatedly; when the same Lua option appears in multiple TOML strings, later occurrences take precedence. With this option, you can set ad-hoc Lua options without creating a config file. For example, to disable the Lua option `stop_early_when_confused`, you can write `--inline-config defaults.stop_early_when_confused=false`. - Support specifying Lua options at the top level of the config file. (suggested by @muzimuzhi in #203, added in #211) This allows you to omit the `[defaults]` section from your config file. For example, the following is now a complete valid config file: ``` toml max_line_length = 120 ignored_issues = ["w100", "S"] ``` This also simplifies the use of the `--inline-config` command-line option: you can now write `--inline-config stop_early_when_confused=false` without the previously required `defaults.` prefix. - Change the semantics of the Lua options `max_reaching_definition_inner_loops` and `max_reaching_definition_outer_loops` to perform a partial reaching definition analysis when the limits are exceeded. (#212, 975f91d) Previously, exceeding either limit would cause explcheck to abort the analysis. Now, processing only aborts when the number of reaching definition loops exceeds the theoretical upper bounds, which indicates a bug. By contrast, when the limits specified by these options are exceeded, explcheck now continues with a partial analysis. This may lead to false positive issues reported by the flow analysis, but can also greatly improve performance. #### Fixes This version of explcheck has fixed the following problems: - Do not report issue W429 (Defined an unexpandable function as unprotected) for restricted-expandable functions. (e507747) - Fix potentially untrue assertion predicates in the flow analysis. (reported by @muzimuzhi in #208, fixed in #209) - Do not expect the `statements` key in all segments. (#212) Some segment types such as `BOOLEAN_EXPRESSION` only contain `calls`, not `statements`. #### Deprecations This version of explcheck has deprecated the following features and scheduled them for removal in v1.0.0: - Rename the Lua option `config_file` to `config_files` and deprecate `config_file`. (#211) - Deprecate the command-line option `--expl3-detection-strategy`. (#211) If you rely on this option, you may set it using `--inline-config`. For example, you would replace `--expl3-detection-strategy always` with `--inline-config 'expl3_detection_strategy = "always"'. #### Continuous integration This version of explcheck has made the following changes to our continuous integration (CI): - Run the flow analysis on the whole TeX Live in the CI. (#208, #210, #212, 975f91d, 59be8c3) - Cancel previous CI run from the same branch or pull request. (cae310d) - Do not run the CI when tags are pushed.

10 May '26

Elayson Abreu submitted an update to the abntexto package. Version: 1.1 2026-05-08 License: pd Summary description: LaTeX class for formatting academic papers in ABNT standards Announcement text: ---------------------------------------------------------------------- A breaking change refers to a change capable of altering older documents if compiled with the current version of the class. - Breaking change. The locators `\listacronymname`, `\listabbreviationname`, and `\listsymbolname` are no longer defined in Portuguese but are initially defined in English (without the presence of babel.sty). This only represents a breaking change in documents that do not load babel, but this is very unlikely; - `\normalsize` is now initialized in `\DeclareOption{10pt}` and `\DeclareOption{11pt}` from now on. - New command `\abntextonote` for inserting notes into tables: `\long\def\note#1{\abntextonote{#1}}` or `\long\def\nt#1{\abntextonote{#1}}`. New commands `\savedabntextonote`, `\abntextonotelabel`, `\printnotebox`; - New command `\setplacepos`; - Added `\gresetORIlabel` to the definition of `subplace`; - The definition of `\alternativesublegend` has been simplified; - New command `\subnote`; - New commands \abntextodecimalcomma, \abntextohyperrefpatch, \abntextodisabledecimalcomma, \abntextodisablehyperrefpatch and \disableautotextual; - New command `\useeletroniclayout`; - Addition to the manual on how the end user can define `\nextoddphysicalpage` to ensure that sections start on the front of the sheets; - Addition to the manual on how the end user can redefine `\bibsetup` to ensure that References are formatted according to NBR~6023:2018; - Addition to the manual regarding the situation where a floating object and a non-floating object are together on the same page with out-of-order numbering. The solution is to avoid floating and non-floating objects on the same page; - Addition to the manual regarding the fact that the latest version is always available on Github (the version on CTAN is not necessarily the most recent); - Addition to the manual: a new subsection on the typographical treatment of quaternary and quinary sections; - In abntexto-exemplo.tex, the abstract in a foreign language must be enclosed in `\selectlanguage`; - In abntexto-exemplo.tex, the cataloging record page cannot have the `\onesidelayout` layout because such a page must be on the back of the title page, therefore `\twosidelayout` was added. In addition, the pre-textual elements were presented on the front side, as recommended by NBR 14724:2024; - The manual stated that "both `\singlesp\onehalfsp` and `\onehalfsp\singlesp` produce the same effect", but this statement is incorrect. The correct statement is "both `\abntsmall\onehalfsp` and `\onehalfsp\abntsmall` produce the same effect"; - The `\sectionmark` in the example in the Headers and Footers section of the Source Code appendix correctly resets `\marks1` from now on; - The commands `\phantomsection`, `\Hy@writebookmark`, and `\NG@gettitle` were defined using `\providecomand`; - A note regarding the occasion when the warning `\tnba@warn@eqbox` (formerly `\tnba@obs@eqbox`) cannot be displayed when it should: during a change in the document's font; - The abntexto-uece class was cited in the manual as a help source for class writers; - Pages in direct quotations in the manual were marked; - An occurrence of NBR 10520 was replaced by NBR 14724 in the manual. ---------------------------------------------------------------------- The package’s Catalogue entry can be viewed at https://ctan.org/pkg/abntexto The package’s files themselves can be inspected at https://mirrors.ctan.org/macros/latex/contrib/abntexto/ ------------------------------------------------------------------------ Thanks for the upload.

CTAN update: expltools
by CTAN Announcements 05 May '26

05 May '26

Vít Starý Novotný submitted an update to the expltools package. Version: 2026-05-03 License: lppl1.3c gpl2+ Summary description: Development tools for expl3 programmers Announcement text: -------------------------------------------------------------------------------- ## expltools 2026-05-03 ### explcheck v0.20.0 #### New features This version of explcheck has implemented the following new features: - Add more support for flow analysis. (#188) This adds support for the following issues from the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors]: 1. E428 (Unexpandable or restricted-expandable boolean expression) 1. W429 (Defined an unexpandable function as unprotected) 2. W502 (Unused private function) 3. W503 (Unused private function variant) Out of these issues, warning W429 is particularly pervasive, being reported for 573 package files in TeX Live 2025. - In `explcheck-latex3.lua`, add `definitions["function"]` and `definitions.variable` properties with LPEG parsers that accept LaTeX3 standard-library function and variable names, respectively, and capture their properties, such as expandability and the date when they were added or most recently updated. (#201, co-authored by @josephwright in latex3/latex3#1885 and latex3/latex3#1886) For example, `lpeg.match(definitions["function"], "msg_expandable_error:nn")`, where `definitions = require("explcheck-latex3").definitions`, returns the Lua table `{ EXP = "full", added = "2015-08-06" }`. These parsers are generated by `generate-explcheck-latex3.lua` from a new third-party submodule at `third-party/latex3`, which points to a reasonably recent version of the LaTeX3 development repository. At commit latex3/latex3@ff6927ae8, the parsers recognize 4,850 LaTeX3 standard-library functions and 339 variables. - Support multiple user config files being specified in the command-line option `--config-file` and the corresponding Lua option `config_file`. (discussed with @muzimuzhi in #203, added in #201) - Add Lua option `defined_csnames` that specifies which control sequences should always be assumed to be defined. (discussed with @muzimuzhi and @alceu-frigeri in #206, added in #201) This option provides a more fine-grained alternative to the earlier `imported_prefixes`. For example, suppose the control sequences `\module_foo:` and `\module_bar:` are imported and should always be considered defined. A coarse-grained way to express this is: ``` toml [defaults] imported_prefixes = ["module"] ``` However, this also suppresses warnings and errors for all control sequence names matching `\module_*`, as well as message names matching `module/*`, which may be undesirable. Using `defined_csnames`, the same intent can be expressed more precisely: ``` toml [defaults] defined_csnames = ["module_foo:", "module_bar:"] ``` This way, only warnings and errors related to the listed control sequence names are suppressed. - Add Lua option `latex3_definitions_max_added_date`, which limits how recent LaTeX3 standard-library function and variable definitions are considered during analysis. (#201) This affects issues E428 and E508 (Unexpandable or restricted-expandable boolean expression) and W429 and W512 (Defined an unexpandable function as unprotected), as well as any issues that are only reported for user-defined functions and variables, not for LaTeX3 standard-library ones. For example, your config file `.explcheckrc` might look as follows if you want to only consider deprecations, prefixes, and definitions from TeX Live 2025 and earlier: ``` toml [defaults] l3obsolete_max_deprecated_date = "2025-09-29" l3prefixes_max_first_registered_date = "2025-12-02" latex3_definitions_max_added_date = "2025-07-08" ``` These dates can be obtained by running `generate-explcheck-latex3.lua` with the Git submodule `third-party/latex3` checked out at a commit corresponding to TeX Live 2025. One reasonable approximation is the Git tag `2026-01-19`, since `/usr/local/texlive/2025/texmf-dist/tex/latex/l3kernel/expl3-code.tex` in the Docker image `texlive/texlive:TL2025-historic` contains `\def\ExplFileDate{2026-01-19}`. The script then produces output such as: ``` LPEG parsers and other information extracted from LaTeX3 data files. Generated on 2026-04-30 from the following files: - "l3obsolete.txt" with the latest obsolete entry from 2025-09-29: `\l_keys_choice_tl` - "l3prefixes.csv" with the latest registered prefix from 2025-12-02: "asmejour" - 85 "l3*.dtx" files with 4,753 function and 340 variable definitions: - Latest added function or variable from 2025-07-08: `\tl_retokenize:n` - Latest updated function or variable from 2025-09-29: `\l_keys_choice_int` ``` #### Warnings and errors This version of explcheck has made the following changes to the document titled [_Warnings and errors for the expl3 analysis tool_][warnings-and-errors]: - Remove planned issues E509 (Expanding an unexpandable function) and E510 (Fully-expanding a restricted-expandable function), since none of these constitute an error: the functions simply remain unexpanded. (#201) - Plan for weaker versions of the issues E508 (Unexpandable or restricted-expandable boolean expression) and W512 (Defined an unexpandable function as unprotected) in semantic analysis under the identifiers E428 and W429, respectively, and the same names. (#201) - Plan for further analysis of integer expressions in Section "Caveats". (#201) #### Continuous integration This version of explcheck has made the following changes to our continuous integration: - Bump `softprops/action-gh-release` from 2 to 3. (contributed by @dependabot in #199) - Check that third-party submodules are up-to-date. (#201) [warnings-and-errors]: https://github.com/witiko/expltools/releases/download/latest/warnings-and-e… -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/support/expltools More information is at https://ctan.org/pkg/expltools -------------------------------------------------------------------------------- Thanks for the upload.
