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.
2021-01-18Add example tmux(1) configKlemens Nanni
Spawn one catgirl per network and handle reconnects through tmux, no extra tool required.
2021-01-17Use Warm heat for blank lines 1.5June McEnroe
So they're not hidden by M-+.
2021-01-16Add -I highlight option and /highlightJune McEnroe
2021-01-16Rename ignore code to filterJune McEnroe
2021-01-16Remove join/part/quit ignore exampleJune McEnroe
These can now be hidden with M-+.
2021-01-16Save and load window visibility thresholdsJune McEnroe
2021-01-16Restore toggling ignore with M--June McEnroe
So that pressing M-- repeatedly maintains the previous behavior.
2021-01-16Generalize ignore toggling to visibility thresholdJune McEnroe
2021-01-11Save and load the URL ring in the save file 1.4June McEnroe
2021-01-11Don't pass nick to urlScan for MOTD and helpJune McEnroe
2021-01-10Check fprintf return values rather than ferrorJune McEnroe
2021-01-10Sandbox with unveil(2) on OpenBSD in restricted modeJune McEnroe
I wrote all this in vi and it was nice.
2021-01-10Print chain to stdout with -oJune McEnroe
2021-01-10Allow interspersing flags and config filesJune McEnroe
Don't wait for getopt_long to move all the arguments to the end. This allows overriding options set by config files by placing flags after them on the command line.
2021-01-10Move -o to a separate SYNOPSIS lineJune McEnroe
2021-01-10Exit immediately when using -oJune McEnroe
2021-01-09Make SYNOPSIS arguments consistent with option namesJune McEnroe
Can't keep the 4-letter pattern forever :(
2021-01-09Add -o and -t options to trust self-signed certificatesJune McEnroe
2021-01-09Allow configuring the upper bound of the hash functionJune McEnroe
This allows limiting the nick colors used to the 16-color terminal set without modifying the TERM environment variable. Produces different results from just using the default configuration in a 16-color terminal, but what can you do?
2021-01-09Count width of 2 for invalid multibyte with high bitJune McEnroe
2021-01-07Use execl rather than execlp for shellJune McEnroe
SHELL is an absolute path.
2021-01-06Sandbox with pledge(2) on OpenBSDJune McEnroe
2021-01-04Collapse whitespace while wrapping and discard trailing spaceJune McEnroe
The latter avoids an extra blank line when a message ends with whitespace that hits the edge of the window.
2021-01-01Split ignore fields to avoid over-eager * matchingJune McEnroe
Split ignore fields and match each separately to avoid an early * eagerly matching across several fields. For example, "* JOIN * *" should not match messages which happen to contain the word "JOIN" followed by two other words. Ignore capacity is reduced to 64 to keep the size of the array the same. I don't think it's an issue.
2020-12-30Factor out reply count checking and decrementingJune McEnroe
2020-12-30Add /whowasJune McEnroe
2020-12-30Show setnames like nick changesJune McEnroe
2020-12-29Add /setname commandJune McEnroe
I'm not sure about that replies check in handleStandardReply. If more of those are added the reply counter system will definitely need refactoring.
2020-12-29Handle so-called Standard RepliesJune McEnroe
2020-12-29Alphabetize STANDARDS sectionJune McEnroe
2020-12-08Document commands which can be filteredJune McEnroe
2020-12-08Clarify the optional portions of an ignoreJune McEnroe
Each optional portion requires the optional portions before it, including a full hostmask.
2020-12-08Fix manual page lintsJune McEnroe
2020-12-08Clarify configuration file usage exampleJune McEnroe
Point to EXAMPLES and /help from the top of the manual.
2020-12-05Handle 437 ERR_UNAVAILRESOURCE like ERR_NICKNAMEINUSEJune McEnroe
Not totally clear under what conditions 437 is returned, but if it happens during registration, we should pick a new nick.
2020-11-24Split /exec lines by \r as well as \nJune McEnroe
This fixes local rendering of /exec toilet --irc, which outputs \r\n line endings.
2020-11-11Add topic diffing to notable features 1.3June McEnroe
