Changes in 6.?.?

This page lists only the most significant changes as remembered. Use git-log to review changes not enumerated here, especially in language parsers.

Critical bug fixes

• fixes a bug where a guest parser with a regex rule using postrun flag could enter an infinite loop.

New and extended options and their flags

New option: --describe-language=<language>

Prints the various aspects of the parser implementing the language.

New column, VER in the output of --list-{kinds-full,roles,fields,extras,pseudo-tags} options

Indicates the versions of ctags output (or the parser) introducing the item in the list.

Extend --map-<LANG>= and --langmap= options to choose a parser using regular expressions

--map-<LANG>=[+]%REXPR% (or --langmap=<LANG>:[+]%REXPR%) maps relative-paths that match the regular expression to the given language.

The new --list-map-rexprs lists all regular-expression-based mappings.

--list-maps has also been extended to include regular-expression-based mappings.

Incompatible changes

Messages for broken symlinks are now emitted at NOTICE level instead of WARNING. They are shown by default, but can be suppressed with the --quiet option.

Parser related changes

JavaScript:

• A new field “properties” was added to indicate that a field or member of a class is static.

• Class member names prefixed with # are recognized as private.

C#:

• Fix a bug that prevents the parser from extracting methods

  if the method has nullable parameters.

Meson:

• Extract config vars defined inside configuration_data({…}).

Python:

• Support type statements.

Clojure:

• Verify namespace when extracting tag.

  The older version doesn’t consider NAMESPACE when processing input like (NAMESPACE/defn foo …).

  With this change, the parser emits functions and/or namespaces kind tags only if NAMESPACES is “clojure.core”. For the other namespaces, the parser emits “unknown” kind tags.

SQL:

• Add type kind to extract t in “CREATE TYPE t ...”.

QemuHX:

• Extract command in { "command", ....

• Implement a selector arbitrating Haxe and QemuHX parsers, both handling

  .hx file extension.

Go:

• Add receiver field to func kind tags.

Rust:

• Add macro field. The Rust parser now extracts definition-like constructs found in macro arguments as tags. For such tags, the parser records the name of the enclosing macro invocation in the macro field.

DosBatch:

• Add batchfile kind to extract the names of batch files passed to call command. New called role is used for recording batch files.

• Add called role to label kind for recording labels passed to call command.

New parsers

The following parsers have been added:

• SINEX: to handle SINEX (Solution INdependent EXchange) files

• Netfilter: to handle the output of “nft list …” command

• Prolog

• DBusService

• GoMod

• Odin

Changes about parser specific kinds, roles, fields, and extras

Readtags

• Update the bundled libreadtags to version 0.5.0.

• Add list operator to the filter and sorter engines. The operator was available only in the formatter expression.

  You can use member and list together.

  e.g. With the following command line, you can list only tag entries having z or p as their kind.

  $ readtags -et tags -Q '(member $kind (list "z" "p" ))' -l
