* Preserve scroll position across reflowsJune McEnroe2021-01-26
| | | | | | | | | | | | 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.
* Add numbers to buffer linesJune McEnroe2021-01-26
| | | | | | | | | 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.
* Rename and move scroll functions closer to where they are usedJune McEnroe2021-01-26
|
* Factor out windowReflowJune McEnroe2021-01-26
|
* Use Warm heat for replies to user-initiated commandsJune McEnroe2021-01-26
| | | | | Otherwise they are invisible with M-+ and commands having no output is confusing.
* Clarify configuration path interpretationsJune McEnroe2021-01-26
|
* Tighten up XDG base directory path handlingJune McEnroe2021-01-26
| | | | | | | 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.
* Expand the opening paragraph of the manualJune McEnroe2021-01-26
|
* Disable notify in restricted modeJune McEnroe2021-01-25
| | | | | catgirl shouldn't try to execute a command if it is misconfigured with both restrict and notify.
* Don't print timestamps for blank lines in bufferListJune McEnroe2021-01-25
|
* Do not copy time to wrapped linesJune McEnroe2021-01-25
|
* Add protocol coverage to non-features listJune McEnroe2021-01-25
| | | | | I don't feel that 100% protocol extension support should at all be a goal.
* Move mention of pledge(2) and unveil(2) to READMEJune McEnroe2021-01-25
| | | | The manual is the wrong place to document platform support.
* Preserve order of filters when removingJune McEnroe2021-01-23
| | | | | | 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.
* Fix /unignore commandJune McEnroe2021-01-23
| | | | Yikes, copy-paste fail.
* Remove use of "%n" to appease de RaadtJune McEnroe2021-01-23
| | | | | | | | | | | | | 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.
* Drop filesystem access iff possibleKlemens Nanni2021-01-23
| | | | | | | 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".
* Drop exec capability iff restrictedKlemens Nanni2021-01-23
| | | | Nothing must be executed when running /copy, et al.
* Drop network capability after ircConnect()Klemens Nanni2021-01-23
| | | | | | 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.
* Call pledge(2) after unveil(2)Klemens Nanni2021-01-23
| | | | | | 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.
* Separate kiosk mode from restrict modeJune McEnroe2021-01-23
| | | | | | | | | | | 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.
* Simplify windowUpdate loops and factor out windowTopJune McEnroe2021-01-21
| | | | | No idea why I made that more complicated than it had to be looping backwards.
* Document that M-l shows timestampsJune McEnroe2021-01-21
|
* Don't lose swapped window when navigating to current bufferJeremy O'Brien2021-01-19
|
* Use Warm heat for manually inserted blank linesJune McEnroe2021-01-19
| | | | Oops, forgot about these.
* Add example tmux(1) configKlemens Nanni2021-01-18
| | | | | Spawn one catgirl per network and handle reconnects through tmux, no extra tool required.
* Use Warm heat for blank lines 1.5June McEnroe2021-01-17
| | | | So they're not hidden by M-+.
* Add -I highlight option and /highlightJune McEnroe2021-01-16
|
* Rename ignore code to filterJune McEnroe2021-01-16
|
* Remove join/part/quit ignore exampleJune McEnroe2021-01-16
| | | | These can now be hidden with M-+.
* Save and load window visibility thresholdsJune McEnroe2021-01-16
|
* Restore toggling ignore with M--June McEnroe2021-01-16
| | | | So that pressing M-- repeatedly maintains the previous behavior.
* Generalize ignore toggling to visibility thresholdJune McEnroe2021-01-16
|
* Save and load the URL ring in the save file 1.4June McEnroe2021-01-11
|
* Don't pass nick to urlScan for MOTD and helpJune McEnroe2021-01-11
|
* Check fprintf return values rather than ferrorJune McEnroe2021-01-10
|
* Sandbox with unveil(2) on OpenBSD in restricted modeJune McEnroe2021-01-10
| | | | I wrote all this in vi and it was nice.
* Print chain to stdout with -oJune McEnroe2021-01-10
|
* Allow interspersing flags and config filesJune McEnroe2021-01-10
| | | | | | 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.
* Move -o to a separate SYNOPSIS lineJune McEnroe2021-01-10
|
* Exit immediately when using -oJune McEnroe2021-01-10
|
* Make SYNOPSIS arguments consistent with option namesJune McEnroe2021-01-09
| | | | Can't keep the 4-letter pattern forever :(
* Add -o and -t options to trust self-signed certificatesJune McEnroe2021-01-09
|
* Allow configuring the upper bound of the hash functionJune McEnroe2021-01-09
| | | | | | | 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?
* Count width of 2 for invalid multibyte with high bitJune McEnroe2021-01-09
|
* Use execl rather than execlp for shellJune McEnroe2021-01-07
| | | | SHELL is an absolute path.
* Sandbox with pledge(2) on OpenBSDJune McEnroe2021-01-06
|
* Collapse whitespace while wrapping and discard trailing spaceJune McEnroe2021-01-04
| | | | | The latter avoids an extra blank line when a message ends with whitespace that hits the edge of the window.
* Split ignore fields to avoid over-eager * matchingJune McEnroe2021-01-01
| | | | | | | | | | 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.
* Factor out reply count checking and decrementingJune McEnroe2020-12-30
