    <p>I'm getting burned repeatedly by unmatched parentheses while writing python code in vim. I like how they're handled for C code - vim highlights in red all of the curly braces following the unmatched paren. I looked at the <code>c.vim</code> syntax file briefly to try to understand it, but the section that handles bracket errors is very complex. Can anyone explain how that code works and suggest how I might write something similar for python code?</p> <p>Example C code with unmatched parens:</p> <pre><code>int main(void { /* brace highlighted in red */ } /* brace highlighted in red */ </code></pre> <p>Since python code doesn't have curly braces to highlight, we'll have to choose something else (perhaps other parentheses).</p> <p>BTW, I tried out <a href="http://www.vim.org/scripts/script.php?script_id=350" rel="noreferrer">this vim plugin</a> but I wasn't happy with the behavior.</p> <p>Edit:</p> <p>I'm using python to generate C++ code (a language that likes parentheses and semicolons). I have a nasty habit of leaving the trailing paren off a <code>file.write()</code> method call. It would be nice if I could get vim to make that mistake more visually obvious.</p> <p><strong>Update:</strong></p> <p>Ok, here's what I've tried so far.</p> <pre><code>:syn region pParen transparent start="(" end=")" contains=ALL :syn match pError display ")" :hi def link pError Error </code></pre> <p>Unfortunately, all this does is highlight as an error the right paren of all <strong>balanced</strong> parentheses, the opposite of what I want to do. I really don't understand what I'm doing here (just copied off of the existing C syntax file). If anyone could explain what I did (wrong), I would appreciate it.</p>

    1. COCan you post some example code? I use python since almost 6 years now and I never had such a problem. Your code sounds pretty unpythonic if you need lots of brackets.

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.
