Hyperlinked grep
=================
This kitten allows you to search your files using `ripgrep
<https://github.com/BurntSushi/ripgrep>`__ and open the results directly in your
favorite editor in the terminal, at the line containing the search result,
simply by clicking on the result you want.
.. versionadded:: 0.19.0
To set it up, first create :file:`~/.config/kitty/open-actions.conf` with the
following contents:
.. code:: conf
# Open any file with a fragment in vim, fragments are generated
# by the hyperlink_grep kitten and nothing else so far.
protocol file
fragment_matches [0-9]+
action launch --type=overlay --cwd=current vim +${FRAGMENT} ${FILE_PATH}
# Open text files without fragments in the editor
protocol file
mime text/*
action launch --type=overlay --cwd=current ${EDITOR} ${FILE_PATH}
Now, run a search with::
kitty +kitten hyperlinked_grep something
Hold down the :kbd:`Ctrl+Shift` keys and click on any of the result lines, to
open the file in :program:`vim` at the matching line. If you use some editor
other than :program:`vim`, you should adjust the :file:`open-actions.conf` file
accordingly.
Finally, add an alias to your shell's rc files to invoke the kitten as
:command:`hg`::
alias hg="kitty +kitten hyperlinked_grep"
You can now run searches with::
hg some-search-term
To learn more about kitty's powerful framework for customizing URL click
actions, see :doc:`here </open_actions>`.
By default, this kitten adds hyperlinks for several parts of ripgrep output:
the per-file header, match context lines, and match lines. You can control
which items are linked with a :code:`--kitten hyperlink` flag. For example,
:code:`--kitten hyperlink=matching_lines` will only add hyperlinks to the
match lines. :code:`--kitten hyperlink=file_headers,context_lines` will link
file headers and context lines but not match lines. :code:`--kitten
hyperlink=none` will cause the command line to be passed to directly to
:command:`rg` so no hyperlinking will be performed. :code:`--kitten hyperlink`
may be specified multiple times.
Hopefully, someday this functionality will make it into some `upstream grep
<https://github.com/BurntSushi/ripgrep/issues/665>`__ program directly removing
the need for this kitten.
.. note::
While you can pass any of ripgrep's comand line options to the kitten and
they will be forwarded to :program:`rg`, do not use options that change the
output formatting as the kitten works by parsing the output from ripgrep.
The unsupported options are: :code:`--context-separator`,
:code:`--field-context-separator`, :code:`--field-match-separator`,
:code:`--json`, :code:`-I --no-filename`, :code:`-0 --null`,
:code:`--null-data`, :code:`--path-separator`. If you specify options via
configuration file, then any changes to the default output format will not be
supported, not just the ones listed.
