v3.13.0

Compare Source

This release introduces support for Zsh
in the parser and formatter, which was tracked in issue #​120
alongside the label https://github.com/mvdan/sh/labels/zsh.
While support is not complete, it should be far enough for many use cases.

This release also drops support for Go 1.24 and includes many other enhancements:

• cmd/shfmt
  • Exit with a non-zero status when -l prints any filenames
  • shfmt -version is now derived from the git current tag, dropping the -ldflags workaround
• syntax
  • New nodes types and node fields are introduced alongside LangZsh
  • LangVariant is now a bitset, allowing the use of sets like "Bash-like"
  • Add InteractiveSeq and StmtsSeq iterator methods for Parser
  • Stop exposing the internal buffer in Printer via struct embedding
  • Support the use of brace expansions like declare {a,b}_c=value
  • Fix a bug where POSIX and Bash incorrectly allowed empty command lists
• interp
  • Add support for shopt -s dotglob and shopt -s extglob
  • Add support for simple uses of !(expr) extended glob patterns
  • Support more builtin flags for declare, type, read
  • Fix various bugs relating to nulls, errors, and arrays
• expand
  • Add Config.DotGlob and Config.ExtGlob for the interpreter
  • Add Variable.Flags to get the one-character declare flags
  • Do not force env vars on Windows to be uppercase
  • Fix various bugs relating to glob pattern matching
• pattern
  • Add GlobLeadingDot and ExtendedOperators for the interpreter
  • Add NegExtGlobError to mark the use of !(expr) negation patterns
