1 [# Safely display user-content text, such a program source code, with
2 line numbers and the ability to comment (if enabled).
4 Other EZT variables used:
5 revision: revision ID string.
6 file_lines: List of lines in the file. Each line
7 has a line number, line content, and list of published and unpublished
9 should_prettify: whether the text should be syntax highlighted.
10 prettify_class: additional CSS class used to tell prettify.js how to
11 best syntax highlight this source file.

14 [# Display the line numbers and source lines in separate columns.
15 See corresponding comments L1, L2, L3 and S1, S2, S3 below.
16 This is messy because the pre tags have significant whitespace, so we
17 break lines inside the tags themslves to make our templates readable.
18 The table has class "opened" or "closed" and the published comment cells
19 and their corresponding gutter cells are conditionally displayed by the
20 CSS rules for the "ifOpened" class. The "hide published comments" link
21 toggles the table's open/closed state.]

23 <td id="nums">
24 [# L1. Start with a nocursor row at the top to space the line numbers down the
25 same amount as the source code lines w/ their initial cursor_hidden row.]

28 [# L2. Display each line number in a row that we can refer
29 to by ID, and make each line number a self-link w/ anchor.
30 If that source line has any published comments, add a nocursor row
31 for spacing to match the corresponding cursor_hidden row, and a gutter
32 cell. The height of the gutter cell is set by JS. Same for unpublished
