Used to query kitty from terminal programs about version, values of various runtime options controlling its features, etc.
The querying is done using the (semi) standard XTGETTCAP escape sequence pioneered by XTerm, so it works over SSH as well. The downside is that it is slow, since it requires a roundtrip to the terminal emulator and back.
If you want to do some of the same querying in your terminal program without depending on the kitten, you can do so, by processing the same escape codes. Search this page for XTGETTCAP to see the syntax for the escape code and read the source of this kitten to find the values of the keys for the various queries.
Command Line Interface¶
kitty +kitten query_terminal [options] [query1 query2 ...]
Query the terminal this kitten is run in for various
capabilities. This sends escape codes to the terminal
and based on its response prints out data about supported
capabilities. Note that this is a blocking operation, since
it has to wait for a response from the terminal. You can control
the maximum wait time via the
The output is lines of the form:
If a particular query is unsupported by the running kitty version, the data will be blank.
Note that when calling this from another program, be very careful not to perform any I/O on the terminal device until the kitten exits.
Available queries are:
name: Terminal name (xterm-kitty) version: Terminal version, for e.g.: 0.19.2 allow_hyperlinks: yes, no or ask
