* loader: rework process modelbptato2024-03-111-15/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* term: improve pixels-per-column/line detectionbptato2024-02-251-0/+8
| | | | | | | | | Some terminal emulators (AKA vte) refuse to set ws_xpixel and ws_ypixel in the TIOCGWINSZ ioctl, so we now query for CSI 14 t as well. (Also CSI 18 t for good measure, just in case we can't ioctl for some reason.) Also added some fallback (optionally forced) config values for width, height, ppc, and ppl. (This is especially useful in dump mode.)
* Separate ANSI text decoding from main binarybptato2024-02-251-6/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Handling text/plain as ANSI colored text was problematic for two reasons: * You couldn't actually look at the real source of HTML pages or text files that used ANSI colors in the source. In general, I only want ANSI colors when piping something into my pager, not when viewing any random file. * More importantly, it introduced a separate rendering mode for plaintext documents, which resulted in the problem that only some buffers had DOMs. This made it impossible to add functionality that would operate on the buffer's DOM, to e.g. implement w3m's MARK_URL. Also, it locked us into the horribly inefficient line-based rendering model of entire documents. Now we solve the problem in two separate parts: * text/x-ansi is used automatically for documents received through stdin. A text/x-ansi handler ansi2html converts ANSI formatting to HTML. text/x-ansi is also used for .ans, .asc file extensions. * text/plain is a separate input mode in buffer, which places all text in a single <plaintext> tag. Crucially, this does not invoke the HTML parser; that would eat NUL characters, which we should avoid. One blind spot still remains: copiousoutput used to display ANSI colors, and now it doesn't. To solve this, users can put the x-ansioutput extension field to their mailcap entries, which behaves like x-htmloutput except it first pipes the output into ansi2html.
* buffer: remove BufferSourcebptato2024-02-221-1/+2
| | | | | | | | | | Aside from being a wrapper of Request, it was just storing the -I charset, except even that didn't actually work. Whoops. This fixes -I effectively not doing anything; now it's a forced override that even disables BOM sniffing. (If the user wants to decode a file using a certain encoding, it seems wise to assume that they really meant it.)
* config: replace default-flags with ignore-casebptato2024-02-221-1/+1
| | | | | | default-flags was overly complicated for its purpose. Also, ignore-case is quite useful, so enable it by default.
* Replace Chakasu with Chagashibptato2024-02-221-1/+1
| | | | | | The API is horrid :( but at least it copies less. TODO: think of a better API.
* regex: re-work compileSearchRegexbptato2024-02-171-5/+29
| | | | | | | I've gotten tired of not being able to search for forward slashes. Now it works like in vim, and you can also set default ignore case in the config.
* term: fix coloring messbptato2024-02-171-2/+3
| | | | | | | | | | | | | | | | | | | | | | | | | Until now, the config file required manual adjustment for the output to look bearable on terminals colored differently than {bgcolor: black, fgcolor: white}. Also, it only detected RGB when COLORTERM was set, but this is not done by most (any?) terminal emulators (sad). To improve upon the situation, we now query the terminal for some attributes on startup: * OSC(10/11, ?) -> get the terminal's bg/fgcolor * DCS(+, q, 524742) -> XTGETTCAP for the "RGB" capability (only supported by a few terminals, but better than nothing) * Primary device attributes -> check if ANSI colors are supported, also make sure we don't block indefinitely even if the previous queries fail If primary device attributes does not return anything, we hang until the user types something, then notify the user that something went wrong, and tell them how to fix it. Seems like an OK fallback. (The DA1 idea comes from notcurses; since this is implemented by pretty much every terminal emulator, we don't have to rely on slow timing hacks to skip non-supported queries.)
* Remove CLONE BufferSource; cache document sources in tmpdirbptato2024-02-121-2/+4
| | | | | | | | | | | | | | | | | | | | | | | At last all BufferSources are unified. To achieve the same effect as the previous CLONE source type, we now use the "fromcache" flag in Request. This *forces* the document to be streamed from the disk; if the file no longer exists for some reason, an error is returned (i.e. the document is not re-downloaded). For a document to be cached, it has to be the main document of the buffer (i.e. no additional resources requested with fetch()), and also not an x-htmloutput HTML file (for those, the original source is saved). The result is that toggleSource now always returns the actual source for e.g. markdown files, not the HTML-transformed version. Also, it is now possible to view the source of a document that is still being downloaded. buffer.sstream has almost been eliminated; it still exists, but only as a pseudo-buffer to interface with EncoderStream and DecoderStream. It no longer holds the entire source of a buffer at any point, and is cleared as soon as the buffer is completely loaded.

* local CGI: add mapped URI env vars; move about: to adaptersbptato2023-12-121-0/+1
| | | | | | | | | | | | | | | * Add MAPPED_URI_* as environment variables when a request is coming from urimethodmap It costs us compatibility with w3m, but it seems to be a massive improvement over smuggling in the URL as a query string and then writing an ad-hoc parser for every single urimethodmap script. The variables are set for every urimethodmap request, to avoid accidental leaking of global environment variables. * Move about: to adapters (an obvious improvement over the previous solution)

* mailcap: add $MAILCAP_URLbptato2023-12-101-1/+1
| | | | | | This is better than %u as it is backwards compatible (i.e. does not rely on other user agents doing whatever upon encountering an unknown substitution template.)
* Separate gopher conversion from main binarybptato2023-12-101-1/+13
| | | | | | | | | | | | | | | | | | | | | Now we use a (much simplified) gopher2html binary in libexec, instead of converting gopher directories to HTML in loader/gopher. This has two advantages: * Less ugly conversion logic in the loader module; we can just convert the file line by line. (The previous converter also had some correctness issues, that is fixed now as well.) * If the user desires, they can replace the gopher converter with another binary using the mailcap mechanism. The disadvantages are: * For now, source display is broken. This is a problem with all mailcap filters in general, and should be fixed in the future. (That said, the previous version also only displayed the converted HTML source, which was not really useful anyway.) * The proper directory structure is required for this to work; OTOH plenty of work has been done so that this is as frictionless as possible, so it should not really be a problem.
* Enable finger protocol by defaultbptato2023-12-101-1/+5

* config: better path handling; fix array parsing bugbptato2023-12-101-17/+33
| | | | | | | | | * Paths are now parsed through an unified code path with some useful additions like environment variable substitution. * Fix a bug in parseConfigValue where strings would be appended to existing arrays (and not override them). * Fix beforeLast calling afterLast for some reason. * Add a default CGI directory.
* pager: add marksbptato2023-12-091-0/+1

* pager, container: add text selection/copyingbptato2023-12-031-0/+2
| | | | | | | | | | * Add select & copy selection functionality to container * Fix bug in generateSwapOutput where output could be misplaced because of zero-width cells * Add fromJSPromise, call runJSJobs in every iteration of the headed event loop * "await" pager actions that output a promise * Change default view source keybinding to `\'
* config: add bare aliases for "8bit", "24bit"bptato2023-11-261-2/+2
| | | | | | | | | | | Without this, setting color-mode using -o required quoting the values, and then shell-quoting the quotes themselves (cha -o 'display-color-mode="24bit"'). Instead of more special casing in the TOML parser, we just add aliases for these enum values that can be parsed using TOML bare string rules. So now this works: cha -o display.color-mode=true-color

* loader: add local-cgibptato2023-09-301-1/+4
| | | | | | | | | | | Add w3m-style local CGI support. It is not quite as powerful as w3m's local CGI, because it lacks an equivalent to W3m-control. Not sure if it's worth adding; we certainly shouldn't allow passing JS in headers, but a custom language for headers does not sound like a great idea either... eh, idk. also, TODO add multipart

| | | | | | | | * it is now possible to jump to the nth line by typing {n}G * gotoLine is now 1-based, so to go to the first line you would use pager.gotoLine(1) * it is now allowed to return a function from a keybinding (which will be subsequently executed as a regular keybinding)

* Add jssetprop, make ActionMap editable from JSbptato2023-08-291-18/+20
| | | | | | | | | jssetprop just adds the set_property exotic function. ActionMap is now editable from JS; the setter is implemented in the same way as bindPagerKey/bindLineKey. (In fact, now those two just call the setter.) But this is still rather inefficient and subject to change.
* javascript: refactorbptato2023-08-281-2/+3
| | | | | | | Split out parts of the JS module, because it was starting to confuse the compiler a little. (Peakmem is back at 750M. Interesting.)
* javascript: de-ref some interfacesbptato2023-08-281-7/+16
| | | | | | | Also, make ActionMap use getters/hasprop instead of a table copy. peakmem remains up +200M at 950M after commit 9991bd3393483158ab0d1b9d995f695dee3c65dc. :(
* config: allow modification through JSbptato2023-08-271-44/+59
| | | | | | | This used to be possible until I moved everything under separate headers to their respective objects. Now it works again, mostly; modification of some attributes is still missing.
