NOTE The primary repository is now at SourceHut.
To use Xeft the note searching interface, install it and type
M-x xeft RET to bring up the panel. If the dynamic module doesn’t already
exists, you are prompted to download or compile it automatically. If
you choose to download the module, no more action is required. If you
want to compile the module locally, refer to the next section for
prerequisites for compiling the module.
Once the Xeft buffer is up, type the search phrase in the first line.
C-p to go through each file. You can preview a file
in another window by pressing
SPC on a file, or click the file with
the mouse. Press
RET to open the file in the current window.
xeft-directory stores note files, directory
xeft-database stores the database. Xeft uses
xeft-default-extension to create new files, and it ignores files
By default, Xeft only searches for first level files in
xeft-directory, to make it search recursively, set
to t. Also beware that Xeft ignores search phrases shorter than three
characters, unless they are CJK characters.
See the “xeft” customize group for more custom options and faces.
On search queries:
Since Xeft uses Xapian, it supports the query syntax Xapian supports:
AND, NOT, OR, XOR and parenthesizes +word1 -word2 which matches documents that contains word1 but not word2. word1 NEAR word2 which matches documents in where word1 is near word2. word1 ADJ word2 which matches documents in where word1 is near word2 and word1 comes before word2 "word1 word2" which matches exactly “word1 word2”
Xeft deviates from Xapian in one aspect: consecutive phrases have
AND between them. So
word1 word2 word3 is actually seen as
word1 AND word2 AND word3.
See https://xapian.org/docs/queryparser.html for Xapian’s official documentation on query syntax.
You can customize the following faces
Functions you can customize to alter Xeft’s behavior:
xeft-filename-fn: How does Xeft create new files from search phrases.
xeft-file-filter: Which files does Xeft include/exclude from indexing.
xeft-recursiveis t, which sub-directories does Xeft include/exclude from indexing.
xeft-title-function: How does Xeft find the title of a file.
xeft-directory-filterare not flexible enough, this function gives you ultimate control over which files to index.
If the dynamic module is not installed yet, Xeft will automatically prompt you to either download a prebuilt module or build the module locally. Prebuilt modules don’t require xapian, but to build the module locally and run it, you need to install xapian.
You can also build by command line:
/opt/local is the default prefix of macports, which is what I
used to install Xapian. Homebrew and Linux users probably can leave it
I can’t test it but on windows you can get msys2 and
make should just work. Thanks to
pRot0ta1p for reporting this.
I owe many thanks to the author of notdeft. I don’t really know C++ or Xapian, without reading his code I wouldn’t be able to write Xeft.
Also, if you want a more powerful searching experience, you will be happier using notdeft instead.
I wrote a xapian dynamic module that you can use too. Check it out at https://git.sr.ht/~casouri/xapian-lite
Why do I still see files that should’ve been ignored after changing
You need to delete the database and let xeft rebuild it, because files already included into the database are not automatically deleted.
How to exclude a directory?
You can customize
to do it.
How to use the file name as excerpt title instead?
(setq xeft-title-function #'file-name-nondirectory)
How to include files in the subdirectories?
;; Don't follow symlinks. (setq xeft-recursive t) ;; Follow symlinks. (setq xeft-recursive 'follow-symlinks)
