* Separate ANSI text decoding from main binarybptato2024-02-2514-268/+587
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Allow non-RGB colors in CSSbptato2024-02-248-180/+252
| | | | | | | | | | | The -cha-ansi color type now sets ANSI colors in CSS. Also, color correction etc. has been improved a bit: * don't completely reset output state in processFormat for new colors * defaultColor is now separated from ANSI color type 0 * bright ANSI colors are no longer replaced with bold + dark variant * replaced ANSI color map to match xterm defaults

* layout: make position: fixed, sticky act like staticbptato2024-02-241-7/+8
| | | | | | | | It's better to not implement them at all than to implement them badly. (In particular, making fixed act like absolute breaks horribly on websites that actually use it. Fixing it is not really possible without changinge the way we currently draw things to the screen.)

* loader: only add output fd to outputMap map in addFdbptato2024-02-241-3/+4
| | | | | | | | It is a very bad idea to add it before that, because it could be closed for various reasons without being removed from the map. More concretely, this was causing ghost ostream fds to block istream selects in some cases.

* buffer: remove BufferSourcebptato2024-02-226-106/+100
| | | | | | | | | | 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.)
* buffer: clean up contentTypebptato2024-02-223-44/+40
| | | | | | | | | | This fixes a bug where setContentType would call setHTML twice, which messed up charsets and probably a couple more things. As a bonus, it allows us to pass around the content type less. In fact, buffer does not have to know its exact content type, just whether it is in HTML mode or not. So that's all we tell it now; only container still keeps track of the content type (as it should).
* config: replace default-flags with ignore-casebptato2024-02-224-12/+19
| | | | | | default-flags was overly complicated for its purpose. Also, ignore-case is quite useful, so enable it by default.
* Replace Chakasu with Chagashibptato2024-02-2224-349/+382
| | | | | | The API is horrid :( but at least it copies less. TODO: think of a better API.
* layout: remove justifybptato2024-02-221-20/+1
| | | | | | | | | | | | | | | | | | The way `justify' was implemented just made text annoying to read. (The algorithm of distributing spacing evenly does not really work on a cell-based screen because of rounding errors.) CSS 2.1 says: > Conforming user agents may interpret the value 'justify' as 'left' or > 'right', depending on whether the element's default writing direction > is left-to-right or right-to-left, respectively. Since we have no bidi yet, just interpret it as `left'. Maybe in the future we could add an implementation that tries to align line box lengths instead of their contents, but this will probably be difficult to get right.
* layout: do not apply error correction to first linebptato2024-02-221-5/+4
| | | | | | The first line is already ignored in the calculations, but it was still being re-positioned in positionAtoms, which made lines overlap in some cases.

* buffer: fix broken jump-to-anchorbptato2024-02-181-1/+1
| | | | | source.request.url is not used after buffer initialization (because it may be replaced later), so we must set buffer.url instead.

* regex: re-work compileSearchRegexbptato2024-02-1711-82/+139
| | | | | | | 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 messbptato2024-02-176-48/+208
| | | | | | | | | | | | | | | | | | | | | | | | | 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.)
* ua.css: remove inline-block from tt, var, font, u, s, strikebptato2024-02-171-1/+1

* css: reduce CSSComputedValue sizebptato2024-02-172-118/+96
| | | | | | | The `t' field was completely redundant, as it's already included in the CSSComputedValues index. + removed some unused functions
* More bgcolor fixesbptato2024-02-171-10/+7

* layout: use html/body bgcolor as canvas bgcolorbptato2024-02-176-46/+74
| | | | | | This is required by the standard. (Without this, lots of websites have incorrect background colors, because they set the body height to 100% of the viewport.)
* layout: only reset charwidth on non-word atomsbptato2024-02-161-1/+1
| | | | | | | | charwidth is specifically intended to represent the width of all characters until the current one, so resetting it for words makes no sense. Originally it was reset for all atoms *except* words; 9fdea97d simplified the code incorrectly (flipped the logic) and thus introduced a regression.

* layout: avoid wrapping on dash inside double-width linesbptato2024-02-161-0/+4

* loader: fix crash on file redirection inputsbptato2024-02-152-16/+60
| | | | | | | | cha -d <some-file was crashing loader, because it was trying to register the regular file in the selector. this patch fixes the problem, but the control flow of loader looks like spaghetti now

* pager: enable wait in runMailcapWritePipebptato2024-02-141-1/+1
| | | | | | Otherwise, container will just happily kill the buffer and with it the loader process before it would have had the chance to stream out the input into the external process.
