    <p>The following bash completion passes an array of possible words (i.e. completions) to compgen.</p> <pre><code>basenames=("foo" "fu bar" "baz"); COMPREPLY=($(compgen -W "${basenames[*]}" -- "${COMP_WORDS[COMP_CWORD]}")) </code></pre> <p>The problem is that the whitespace in the array elements is not preserved, that is "foo bar" is treated as to elements thanks to word splitting. Is there some way to preserve the whitespace, so that 3 elements are shown, and not 4?</p> <p><strong>EDIT</strong></p> <p><code>basenames</code> contains filenames, that is nearly every character (apart from / and \0) is allowed.</p> <p><strong>EDIT 2</strong></p> <p>The -W flag expects a single word, that is something like <code>foo bar foobar</code>. Passing multiple elements to it (this is what <code>${basenames[@]}</code> would do) won't work.</p> <p><strong>EDIT 3</strong></p> <p><em>Changed examplary basenames array (so the <code>foo</code> and the <code>foo</code> from <code>foo bar</code> won't get collapsed).</em></p> <p>Using a newline to separate the words works:</p> <pre><code>local IFS=$'\n' COMPREPLY=($(compgen -W "$(printf "%s\n" "${basenames[@]}")" -- ${COMP_WORDS[COMP_CWORD]}")) </code></pre> <p>Using <code>\0</code> doesn't:</p> <pre><code>local IFS=$'\0' COMPREPLY=($(compgen -W "$(printf "%s\0" "${basenames[@]}")" -- ${COMP_WORDS[COMP_CWORD]}")) </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
