Daniel Shahaf d5d2f22013 Revert "test harness: Rewrite the columnar pretty-printer without external tools." and "travis: Remove bsdmainutils since column(1) has been removed, three commits ago." 
This reverts commits ea7c165b59 and
3d81c83132.

When "have 6 expectations and 4 region_highlight entries", the pure-zsh
implementation printed them as follows:

    not ok 7 - cardinality check - have 6 expectations and 4 region_highlight entries: «expected_region_highlight=( $'1 1 builtin' $'3 6 comment' $'8 13 comment' $'15 15 default' $'16 21 comment' $'22 22 default' )»
    «region_highlight=( $'0 1 builtin' $'2 6 comment' $'7 13 comment' $'14 22 default' )»
    # expected_region_highlight  '22 22 default'
    # '1 1 builtin'              region_highlight
    # '3 6 comment'              '0 1 builtin'
    # '8 13 comment'             '2 6 comment'
    # '15 15 default'            '7 13 comment'
    # '16 21 comment'            '14 22 default'

Whereas the column(1)-based implementation prints them as follows:

    not ok 7 - cardinality check - have 6 expectations and 4 region_highlight entries: «expected_region_highlight=( $'1 1 builtin' $'3 6 comment' $'8 13 comment' $'15 15 default' $'16 21 comment' $'22 22 default' )» «region_highlight=( $'0 1 builtin' $'2 6 comment' $'7 13 comment' $'14 22 default' )»
    # expected_region_highlight  region_highlight
    # '1 1 builtin'              '0 1 builtin'
    # '3 6 comment'              '2 6 comment'
    # '8 13 comment'             '7 13 comment'
    # '15 15 default'            '14 22 default'
    # '16 21 comment'
    # '22 22 default'

Ultimately, this difference is down to the pure-zsh implementation
getting the arguments as a single list, whereas paste(1) gets two
separate lists.

zsh-syntax-highlighting Build Status

Fish shell-like syntax highlighting for Zsh.

Requirements: zsh 4.3.11+.

This package provides syntax highlighting for the shell zsh. It enables highlighting of commands whilst they are typed at a zsh prompt into an interactive terminal. This helps in reviewing commands before running them, particularly in catching syntax errors.

Some examples:

Before: Screenshot #1.1
After:  Screenshot #1.2

Before: Screenshot #2.1
After:  Screenshot #2.2

Before: Screenshot #3.1
After:  Screenshot #3.2

Before: Screenshot #4.1
After:  Screenshot #4.2

How to install

See INSTALL.md.

FAQ

Why must zsh-syntax-highlighting.zsh be sourced at the end of the .zshrc file?

zsh-syntax-highlighting.zsh wraps ZLE widgets. It must be sourced after all custom widgets have been created (i.e., after all zle -N calls and after running compinit). Widgets created later will work, but will not update the syntax highlighting.

Does syntax highlighting work during incremental history search?

Highlighting the command line during an incremental history search (by default bound to to Ctrl+R in zsh's emacs keymap) requires zsh 5.4 or newer.

Under zsh versions older than 5.4, the zsh-default underlining of the matched portion of the buffer remains available, but zsh-syntax-highlighting's additional highlighting is unavailable. (Those versions of zsh do not provide enough information to allow computing the highlighting correctly.)

See issues #288 and #415 for details.

How are new releases announced?

There is currently no "push" announcements channel. However, the following alternatives exist:

How to tweak

Syntax highlighting is done by pluggable highlighter scripts. See the documentation on highlighters for details and configuration settings.
