2 | * info backend for Halibut |

4 | * Possible future work: |
5dd44dce |
5 | * |
b921687e |
6 | * - configurable choice of how to allocate node names? |
7 | * + possibly a template-like approach, choosing node names to |
8 | * be the full section title or perhaps the internal keyword? |
9 | * + neither of those seems quite right. Perhaps instead a |
10 | * Windows Help-like mechanism, where a magic config |
11 | * directive allows user choice of name for every node. |
12 | * + Only trouble with that is, now what happens to the section |
13 | * numbers? Do they become completely vestigial and just sit |
14 | * in the title text of each node? Or do we keep them in the |
15 | * menus somehow? I think people might occasionally want to |
16 | * go to a section by number, if only because all the _other_ |
17 | * formats of the same document will reference the numbers |
18 | * all the time. So our menu lines could look like one of |
19 | * these: |
20 | * * Nodename: Section 1.2. Title of section. |
21 | * * Section 1.2: Nodename. Title of section. |
5dd44dce |
22 | * |
b921687e |
23 | * - might be helpful to diagnose duplicate node names! |
c2d30a0d |
24 | * |
c2d30a0d |
25 | * - Indices generated by makeinfo use a menu rather than a bunch of |
26 | * cross-references, which reduces visual clutter rather. For |
27 | * singly-referenced items, it looks like: |
28 | * * toner cartridge, replacing: Toner. |
29 | * It does a horrid job on multiply-referenced entries, though, |
30 | * perhaps because the name before the colon is meant to be unique. |
22e33bba |
31 | * Info's 'i' command requires the use of a menu -- it fails to |
32 | * find any index entries at all with Halibut's current index format. |
c2d30a0d |
33 | * |
34 | * - The string "*note" is matched case-insensitively, so we could |
35 | * make things slightly less ugly by using the lower-case version |
36 | * when the user asks for \k. Unfortunately, standalone Info seems |
37 | * to match node names case-sensitively, so we can't downcase that. |
