handle tab characters tab characters have their width depending on the column they're in, since they extend to the next multiple of 8. (citation needed?) So, keep track of the column when considering the length (in columns) of the text, so that we can render them properly. In the future we might want to turn them into spaces (either at read or render time) just to stay on the safe side in case not all terminals/ncurses implementations use 8 columns.

use a byte offset to track the point in the line Instead of using a code-point offset, use a raw byte offset and navigate backward and forward by means of graphemes. This gives a correct "visual" backward/forward navigation through characters.

constify the parser structs

untangle a bit buffers and parsers Now buffers have a nicer interface, taking explicitly the buffer where they push stuff, and the code that deals with buffers doesn't need to peek into the parsers. The parsers now are 'pure' structs without state attached to them, the state was moved to the buffer.

update telescope to make use of mailcap Change telescope to make use of mailcap entries. Commands are no longer prompted for how to handle an unknown mime-type. Commands are now executed via execvp(), and the mailcap handling assumes this as part of its interface.

ui: add capability to run external cmds When telescope encounters a file type which it cannot display it prompts the user whether they wish to save the file, or not. This patch extends this idea -- if the file is saved, then the user is prompted to run a command against that downloaded file. This controllable via the 'external-cmd' setting. It defaults to 'xdg-open'. This is based off work originally started by op@.

parsers: add a parseline method all our parsers just need a line to parse and don't always need the free method. The gemtext parser could also be simplified with this, but defer it for later.

typo

remove unused printfn typedef

tls: guard against faulty gemini servers Some gemini servers have faulty TLS handling, such as: gg: tls_close: EOF without close notify In such cases, telescope will receive that error and naturally assume there was a problem and stop processing. However, in the case of there still being legitimate content read from the request, this should still be displayed, rather than ignored. This change therefore detects this condition and adds a status of 'W' to telescope's modeline to indicate that the information presented is from a faulty gemini server and could be truncated and hence display oddly.

move imsgev & co to their own file This avoids bringing the dependency on ev on telescope-identity(1) and the tests as well.

convert telescope to use ev instead of libevent libevent is a very cool library, I like the APIs and enjoy using it. However, telescope is not as large and doesn't have as many file descriptor, so libevent is quite ``too big'' for our needs. ev started as a small event loop on top of poll(2) for amused, and can be used here too, it just needed to grow the ability to handle several timers, as we need quite some on telescope (in fact, we use more timers than fds!)

add client_cert_temp flag to the struct tab This way we can improve unload-certificate prompt. While here, move the cert handling in make_request().

move tofu declarations to their own header While here replace GEMINI_URL_LEN with TOFU_URL_MAX_LEN to avoid a dependency on telescope.h. Ideally, we should move this stuff to another header that comes with less dependencies.

include compat.h explicitly in all files don't do it in telescope.h, remove telescope.h from gencmd.awk and sort the headers in parse.y while here.

move struct cmd and cmds declaration in cmd.h

include cmd.h only where it is really needed

first draft of client certificate support At the moment telescope loads a mapping host:port/path -> certificate from a file and always uses it, no ways to change it, use a temporary one, generate a new one, etc are provided yet. The format of ~/.telescope/certs/certs is host port path certificate file name where the certificate file name is the name of a file inside ~/.telescope/certs. ~/.telescope/certs/ is ~/.local/share/telescope/ when using XDG.

send the reply code and meta in a single imsg

inline dispatch_imsg(); start to use some newer imsg api

move includes back to the root directory Splitting stuff into sub-directories was just a big mistake.
