* pager, mailcap: misc fixes, add prompt for global mailcapbptato2024-12-111-4/+8
| | | | | | | | | | | | | | | | | | | | | | | | In the past, Chawan would read global mailcap (/etc/mailcap, ...) too, but every now and then that would run entries that I didn't even know existed and definitely didn't intend to run. So I changed it to only use ~/.mailcap, but this meant users now had to add mailcap entries for every single mime type. At some point I also changed application/octet-stream to always save to disk, which is usually nice except when a text file is misrecognized as binary. Often times I just want to decide myself what to do. So now there are two layers. First, the global mailcap files (path as per RFC) prompt before executing. Then there is ~/.chawan/auto.mailcap (or ~/.config/chawan/auto.mailcap) which runs entries automatically. If you press shift before selecting an option in the prompt, the corresponding entry gets copied to auto.mailcap. It's also possible to type a new entry on the fly. Overall I think it's quite convenient. One unfortunate side effect is that existing users will have to migrate their entries to auto.mailcap, or redefine external.auto-mailcap to e.g. ~/.mailcap, but this seems acceptable.

* mimetypes: refactor, use mime.types for inline image extensionsbptato2024-12-051-1/+18
| | | | | | | | | | | | * remove std/streams use from mime.types; mmap and parse directly * use mime.types for inline image extensions * add some jpeg file extensions Latter came up because I was trying to add a format locally and it wouldn't recognize it on images from my file system (i.e. by extension). As a security measure we still do not allow additional extensions for predefined inline image types.

* config: refactor, accept more possible config dirsbptato2024-10-281-0/+6
| | | | | | | | | | | | | | | | | | | | | I'm starting to favor dotfiles over XDG basedirs, but there's no reason why we couldn't have both. So now the search path is: 0. if config was set through -C, use that 1. $CHA_CONFIG_DIR is set -> $CHA_CONFIG_DIR/config.toml 2. $XDG_CONFIG_HOME is set -> $XDG_CONFIG_HOME/chawan/config.toml 3. ~/.config/chawan/config.toml exists -> use that 4. ~/.chawan/config.toml exists -> use that Notably, this makes it so the default directory is ~/.chawan *if* you don't have an existing config.toml file. So in that case known_hosts will be placed in ~/.chawan/known_hosts. However, configurations with a config in ~/.config/chawan/config.toml continue to work as expected, as for those the known_hosts file remains inside ~/.config/chawan/. Finally, I've added a default user CGI directory to reduce friction in setting CGI up. (Like known_hosts, it's also relative to whatever config dir you have.)

* utils: add twtunibptato2024-09-081-11/+9
| | | | | | | | | | | | | | | | | | | std/unicode has the following issues: * Rune is an int32, which implies overflow checking. Also, it is distinct, so you have to convert it manually to do arithmetic. * QJS libunicode and Chagashi work with uint32, interfacing with these required pointless type conversions. * fastRuneAt is a template, meaning it's pasted into every call site. Also, it decodes to UCS-4, so it generates two branches that aren't even used. Overall this lead to quite some code bloat. * fastRuneAt and lastRune have frustratingly different interfaces. Writing code to handle both cases is error prone. * On older Nim versions which we still support, std/unicode takes strings, not openArray[char]'s. Replace it with "twtuni", which includes some improved versions of the few procedures from std/unicode that we actually use.

* Remove unnecessary unsigned castsbptato2024-04-261-1/+1

* data: replace std/base64 with atobbptato2024-04-251-0/+63
| | | | | | | | | | std's version is known to be broken on versions we still support, and it makes no sense to use different decoders anyway. (This does introduce a bit of a dependency hell, because js/base64 depends on js/javascript which tries to bring in the entire QuickJS runtime. So we move that out into twtstr, and manually convert a Result[string, string] to DOMException in js/base64.)

| | | | | | | Better compute the values we need on-demand at the call sites; this way, we can pass through content type attributes to mailcap too. (Also, remove a bug where applyResponse was called twice.)
* loader: rework process modelbptato2024-03-111-62/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally we had several loader processes so that the loader did not need asynchronity for loading several buffers at once. Since then, the scope of what loader does has been reduced significantly, and with that loader has become mostly asynchronous. This patch finishes the above work as follows: * We only fork a single loader process for the browser. It is a waste of resources to do otherwise, and would have made future work on a download manager very difficult. * loader becomes (almost) fully async. Now the only sync part is a) processing commands and b) waiting for clients to consume responses. b) is a bit more problematic than a), but should not cause problems unless some other horrible bug exists in a client. (TODO: make it fully async.) This gives us a noticable improvement in CSS loading speed, since all resources can now be queried at once (even before the previous ones are connected). * Buffers now only get processes when the *connection* is finished. So headers, status code, etc. are handled by the client, and the buffer is forked when the loader starts streaming the response body. As a result, mailcap entries can simply dup2 the first UNIX domain socket connection as their stdin. This allows us to remove the ugly (and slow) `canredir' hack, which required us to send file handles on a tour accross the entire codebase. * The "cache" has been reworked somewhat: - Since canredir is gone, buffer-level requests usually start in a suspended state, and are explicitly resumed only after the client could decide whether it wants to cache the response. - Instead of a flag on Request and the URL as the cache key, we now use a global counter and the special `cache:' scheme. * misc fixes: referer_from is now actually respected by buffers (not just the pager), load info display should work slightly better, etc.
