* degesch: slightly cut down memory usagePřemysl Eric Janouch2020-10-191-16/+25
| | | | | | | | | | | | | | | | | | | The worst offenders are actually OpenSSL and Lua, this is mostly about a preventable surprise. This is more correct because we mix escape sequences for attributes with text, however in practice no one will use shit-jizz with degesch. It is also a clean-up: "struct line_char" has been almost halved in size. We used to use it as a cache and now we recompute the multibyte sequence. Of course, it'd be best to get rid of the linked list but it would take a very long time to rewrite the algorithm. Plus, it's not certain that it could be improved by much. The change in "struct line_char_attrs" is merely cosmetical.

| | | | | Channels now need a reference to the server, so don't pass it to functions.
* degesch: watch away statuses with away-notify/WHOPřemysl Eric Janouch2020-10-161-19/+106
| | | | | We're not going to implement polling. Polling is complex. Freenode supports away-notify.

| | | | 3_3_3_3_4 looks awful and it wasn't even precise.
* Tolerate cut-off UTF-8 messagesPřemysl Eric Janouch2020-10-121-1/+22
| | | | | | | | I've had this happen to me on Russian channels and it's highly annoying because you lose the entire message. On the contrary, this at worst screws up the last few characters of it. Closes #2

| | | | Let's say the rest is in Oxford spelling, not sure about it.
* Bump libertyPřemysl Eric Janouch2020-10-101-1/+1
| | | | resolve_relative_runtime_unique_filename() used to have a bug.
* degesch: fix prompt not showing up after changePřemysl Eric Janouch2020-10-061-5/+3
| | | | | | | | | | | | | When a backlog helper was running and the prompt changed, it failed to restore within input_rl_show(). Since before input_rl_show() is called the prompt is empty and in input_rl__restore() it will be changed to the new version, just skip invoking any Readline functions within input_rl_set_prompt() when the prompt is hidden. Simple and straight-forward. This bug is what I hinted at in the previous commit.
* degesch: enable wrapping in the backlog by defaultPřemysl Eric Janouch2020-10-041-1/+1
| | | | The main issue has been eliminated.
* degesch: resolve the issue with less(1) and SO/SIPřemysl Eric Janouch2020-10-041-10/+25
| | | | | | | | | Now that I've learnt what exactly these characters are and how they ended up in attribute strings, we can just eliminate them and disable `backlog_helper_strip_formatting`. Saner defaults, again. I've also added skipping of terminfo delay sequences, so now it's less of an issue to pipe raw attribute sequences into backlog helpers.
* degesch: make the unread marker look a bit fancierPřemysl Janouch2020-10-041-1/+27
| | | | | | | | | | | | | | | | | | Upstreamed after who knows how long, in a slightly modified form. The marker looks fairly ugly without this and defaults should be desirable. It's possible to get the previous behaviour by resetting the separator character in the configuration to an empty string. It might be a better idea in general to just disallow this value with a special validation callback, so that there's only one way to do it. However given that without fancy-prompt.lua, an optional plugin, the long line stands out considerably, it might actually be a good idea to keep the old behaviour as the default. I'm torn. Right now we don't care about the situation where the string occupies more than one terminal cell or is some Unicode BS. User's problem.

| | | | | `struct str` was mostly unnecessary, we can save 16+ bytes, while performance and code readability is mostly unchanged.

* Relicense to 0BSD, update mail addressPřemysl Janouch2018-06-211-3/+2
| | | | | | | | | I've come to the conclusion that copyright mostly just stands in the way of software development. In my jurisdiction I cannot give up my own copyright and 0BSD seems to be the closest thing to public domain. The updated mail address, also used in my author/committer lines, is shorter and looks nicer. People rarely interact anyway.
