Re: [ jEdit-users ] Ctagsinterface searching

[Shlomy R. <sre...@gm...>]

Hi,

For some reason, gmail removed the bullets from the original email
when I clicked "reply".

Please note that I am currently changing CtagsInterface to use Lucene
(full text search engine) instead of a relational database for storing
the tag database. There are several reasons for this change - it
improves performance greatly, and provides a lot of flexibility in tag
lookup (e.g. you can use fuzzy searches, where you don't remember the
precise name of a tag). The is a very large change and affects most of
the answers.

1. This is possible with the trunk version, but not with the released
version. CtagsInterface has 'dynamic actions' that allow you to write
queries that will result in tags to jump to. A few weeks ago, someone
contributed a patch that allows you to use these queries also for the
"Search for a tag with prefix" popup. When you enter the query, you
can select whether you want to jump to the tag that is produced as a
result of the query, or open this popup with the results. Using this
feature, you can write a query that will find all functions, and have
the popup let you choose only between functions.
However, this is not a good solution, as most likely you'll have
numerous functions to select from. Once I'm done porting
CtagsInterface to Lucene, this will be much simpler, as Lucene queries
are much more flexible. I'll be able to enhance this popup to support
Lucene queries.

2. Case-insensitive search will be enabled when the port to Lucene is completed.

3. "Search for substring" is also case-sensitive. It should work fine,
but it can take a lot of time, as the plugin creates a data structure
in-memory to support this (this is one of the reasons why I am
switching to Lucene).
"Search with prefix" has no wildcards support as of now.

4. I am not sure about the Tags plugin. CtagsInterface also has an
option to "import" an existing tag file, however I think that Tags
supports tag files on VFS (e.g. ftp), while CtagsInterface currently
only supports tag files on locally-mounted file-systems. If your tag
files are local, no need to use Tags. If your sources are in
locally-mounted file-systems only, there is also no need to use tag
files, as CtagsInterface will run Ctags for you and keep the tag
information up-to-date automatically.

5. To use the completion, type the prefix of a function name and
select this action. It should show a small completion popup. Note that
this is also case sensitive. In general, note that if you can type the
entire function name and jump to it using the plugin, then typing a
prefix of the function name and selecting this action should include
the entire name in the completion options. For functions, this should
also complete the signature (i.e. show you templates for the
parameters, using the SuperAbbrevs plugin).

The downside of the switch to Lucene is, that you'll have to delete
your existing tag database and recreate it from scratch using Lucene.
The advantages with Lucene are huge, so it's worth it ...
