2021-02-27Add workaround for lack of A_ITALIC in old ncursesJune McEnroe
A_BLINK has probably always existed, but there's no good reason to ever use it, so make it do italics instead. Normally all attributes are set by a single set_attributes string if it's set, so clear it to force ncurses to use the reassigned enter_blink_mode string. If the terminal has no enter_italics_mode string, then nothing will happen. This makes setting multiple attributes a bit less efficient, but I don't think it's likely to make much of a difference since using multiple attributes at once is so uncommon.
2021-02-25Error if hash bound is less than 2June McEnroe
Bad things happen otherwise.
2021-02-21Use separate reply counts for automatic join topics/namesJune McEnroe
This restores showing the topic and names for automatic joined channels, while still avoiding touching the windows, by using Cold heat.
2021-02-15Add C-z p to manually toggle paste modeJune McEnroe
OpenBSD's xterm doesn't have bracketed paste mode, and it would be nice to still be able to paste in several lines and collapse them with M-q, provided one remembers to type C-z p first...
2021-02-15Refactor Focus and Paste mode stringsJune McEnroe
2021-02-15Don't insert wchar_t if it can't be converted to mbsJune McEnroe
Otherwise it could hit the assertion in editBuffer while converting to mbs for consumption by the rest of the program. It's possibly to trigger this with LC_ALL=C and typing C-z C-v M-a, for example.
2021-02-15Don't expand macro if it can't be converted to mbsJune McEnroe
Otherwise expanding a macro could hit the assertion in editBuffer while converting to mbs for consumption by the rest of the program.
2021-02-08Add donation link to README 1.6June McEnroe
2021-02-08Fix /help LESS setting for updated manualJune McEnroe
The new reference to the COMMANDS section at the beginning of the manual would get matched instead.
2021-02-08chat.tmux.conf: Add help window for restricted mode, use neww -SKlemens Nanni
Provide a hotkey to browser the manual in its own window. After input, nicm (tmux upstream) added "-S" to tmux(1) such that the "new-window" command (in combination with "-d") first looks for the given window name and selects the window if it exists instead of trying to create a window that already exists. Given that this makes chat.tmux.conf idempotent, we can now also reload it at runtime to refresh settings.
2021-02-04Only treat a single -j join as explicitJune McEnroe
In other words, only automatically switch to an automatically joined channel window if there's only one. Otherwise, stay on the <network> window and avoid touching the channel windows with their automatic topic and names replies. This fixes unintentionally clearing saved window unread counts when rejoining channels automatically by switching to them as they are joined.
2021-02-03Add C-z C-v for literal nextJune McEnroe
A little annoying to make it a "chord" like this, but C-v is already used for scrolling, following Emacs-style key bindings (in order to have a way to scroll without using "special" keys like the arrows and page up/down), and C-z is at least already in the business of inserting control characters. This makes it possible to manually enter some things that are otherwise only possible with /exec printf.
2021-02-03chat.tmux.conf: Improve respawn, fix commentKlemens Nanni
Only respawn the pane not the entire window to avoid killing other possibly existing panes in the same window.
2021-01-31Also skip marking swap windowJune McEnroe
Third time's the charm?
2021-01-29Actually scroll to first line for "scroll to top"June McEnroe
2021-01-29Only skip setting swap in windowShowJune McEnroe
With the early return, mainUpdate doesn't get called in cases where other functions expect windowShow to call it, such as when closing or moving windows.
2021-01-28Add Repology links to READMEJune McEnroe
LibreTLS in particular is gaining traction in packaging, so point to Repology pages to make users' lives easier.
2021-01-28Add key bindings to chat.tmux.conf, nitsKlemens Nanni
2021-01-28Add 335 to WHOIS responsesJune McEnroe
This is used by InspIRCd to indicate if a user is a bot (if it set user mode +B).
2021-01-28Move threshold and mute indicators directly after numberJune McEnroe
I don't know why I ruled this out originally, it's more visually pleasing to me now especially that threshold is likely to remain set at "+" for a long time.
2021-01-27Save window time display toggleJune McEnroe
2021-01-27Measure timestamp width using ncursesJune McEnroe
This allows for non-ASCII characters in timestamps, and simplifies things by including the trailing space in the width.
2021-01-27Change default timestamp format to %XJune McEnroe
This respects the user's locale settings.
2021-01-27Add toggleable display of timestampsJune McEnroe
2021-01-26Only list up until scroll position with M-lJune McEnroe
2021-01-26Preserve scroll position across reflowsJune McEnroe
Finally! Changing the message visibility threshold doesn't totally screw up scroll position. Neither do horizontal resizes, but vertical resizes drift because the value of windowTop() changes before and after... The scroll position is anchored to the top of the window. It's arbitrary whether to anchor the top or the bottom, but other scrolling commands like M-p and C-r are anchored to the top, so this is consistent.
2021-01-26Add numbers to buffer linesJune McEnroe
This directly correlates hard-wrapped lines with the soft lines they were wrapped from. Choosing uint here because it doesn't change the size of struct Line. It doesn't at all matter since buffers only hold 1024 lines at a time anyway.
2021-01-26Rename and move scroll functions closer to where they are usedJune McEnroe
2021-01-26Factor out windowReflowJune McEnroe
2021-01-26Use Warm heat for replies to user-initiated commandsJune McEnroe
Otherwise they are invisible with M-+ and commands having no output is confusing.
2021-01-26Clarify configuration path interpretationsJune McEnroe
2021-01-26Tighten up XDG base directory path handlingJune McEnroe
Don't search base directories if path starts with "/", "./" or "../", but still do if the path simply starts with ".". Bail early if HOME is needed but unset. Don't attempt to open the original path in configOpen and dataOpen.
2021-01-26Expand the opening paragraph of the manualJune McEnroe
2021-01-25Disable notify in restricted modeJune McEnroe
catgirl shouldn't try to execute a command if it is misconfigured with both restrict and notify.
2021-01-25Don't print timestamps for blank lines in bufferListJune McEnroe
2021-01-25Do not copy time to wrapped linesJune McEnroe
2021-01-25Add protocol coverage to non-features listJune McEnroe
I don't feel that 100% protocol extension support should at all be a goal.
2021-01-25Move mention of pledge(2) and unveil(2) to READMEJune McEnroe
The manual is the wrong place to document platform support.
2021-01-23Preserve order of filters when removingJune McEnroe
Filters should be kept in order since the first one that matches, wins. This lets highlights or ignores take priority over each other, if desired.
2021-01-23Fix /unignore commandJune McEnroe
Yikes, copy-paste fail.
2021-01-23Remove use of "%n" to appease de RaadtJune McEnroe
Sure, it was completely unnecessary, but I resent being told how to use snprintf. https://cvsweb.openbsd.org/src/lib/libc/stdio/vfprintf.c?rev=1.79&content-type=text/x-cvsweb-markup Notes: My problem here is with yelling about a standard C feature that has legitimate uses, simply because it *could* be used in a way that might cause security issues. If you're going to do that, you may as well syslog(3) whenever someone runs any C code at all.
2021-01-23Drop filesystem access iff possibleKlemens Nanni
Log files and state save/restore both require read/write access to the filesystem, both during start and exit. If neither features are used, catgirl may run with "stdio tty".
2021-01-23Drop exec capability iff restrictedKlemens Nanni
Nothing must be executed when running /copy, et al.
2021-01-23Drop network capability after ircConnect()Klemens Nanni
catgirl has no reconnect feature and generally must not do anything but read/write from/to the connected socket which does not require "inet" or "dns" promises.
2021-01-23Call pledge(2) after unveil(2)Klemens Nanni
Simplify logic, be more idiomatic and finalize by pledging after all unveiling is done by omitting the "unveil" promise and thereby not allowing further calls to it.
2021-01-23Separate kiosk mode from restrict modeJune McEnroe
Restrict mode will focus on sandboxing, while kiosk will continue to restrict IRC access through a public kiosk. Kiosk mode without restrict mode allows execution of man 1 catgirl with /help, assuming external sandboxing. The /list and /part commands are also added to the list of disabled commands in kiosk mode, since they are pointless without access to /join.
2021-01-21Simplify windowUpdate loops and factor out windowTopJune McEnroe
No idea why I made that more complicated than it had to be looping backwards.
2021-01-21Document that M-l shows timestampsJune McEnroe
2021-01-19Don't lose swapped window when navigating to current bufferJeremy O'Brien
2021-01-19Use Warm heat for manually inserted blank linesJune McEnroe
Oops, forgot about these.
