* container: fix cursor positioning bugsbptato2024-02-281-6/+24
| | | | | | | | | * fix cursor jumping back to the start of the line (instead of the end of the line) when it is outside the viewport and a leftwards update is requested * save setxsave too when line is not loaded yet * always set needslines in onMatch when hlon (this was causing a blank screen when incremental search was jumping around in large documents)
* buffer: add image viewer supportbptato2024-02-271-24/+23

* misc refactoringsbptato2024-02-271-5/+5
| | | | | | * rename buffer enums * fix isAscii for char 0x80 * remove dead code from URL
* buffer: reset prevStyled in switchCharset, reshapebptato2024-02-271-9/+3
| | | | | | | | reshape must do a render from zero, as it's a last resort for users to fixup the page on a rendering bug. switchCharset must reset prevStyled for obvious reasons (it refers to a dead document).
* pager: do not add replacement containersbptato2024-02-261-1/+3
| | | | | they will replace the target container on connection, so inserting them in a different place first results in strange navigation bugs
* buffer: clean up onload, fix console updatebptato2024-02-262-42/+40
| | | | | | | | | | | | * reduce onload result size to a single int * clean up mess that was the container onload handler This fixes automatic refresh in console. Before, the client would only request a screen update after receiving the number of bytes read, but before the screen was actually reshaped (which obviously resulted in a race condition). Now, "I've reshaped the document" is a separate response (and is the only occasion where the screen is updated before the final render).
* term: improve pixels-per-column/line detectionbptato2024-02-253-20/+17
| | | | | | | | | 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 binarybptato2024-02-252-45/+88
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* pager: fix wrong referrer in redirectTobptato2024-02-231-1/+1

* buffer: remove BufferSourcebptato2024-02-222-38/+30
| | | | | | | | | | 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 contentTypebptato2024-02-222-26/+36
| | | | | | | | | | 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-casebptato2024-02-221-4/+10
| | | | | | default-flags was overly complicated for its purpose. Also, ignore-case is quite useful, so enable it by default.
* Replace Chakasu with Chagashibptato2024-02-223-3/+3
| | | | | | The API is horrid :( but at least it copies less. TODO: think of a better API.
* container: fix crash on clone -> view sourcebptato2024-02-191-5/+9
| | | | | * set loaderPid in clones too * handle URL in container the same way as in buffer
* client: fix EOF error for estreambptato2024-02-181-0/+2

* pager: fix compilation on 1.6.14bptato2024-02-171-1/+1
|
* regex: re-work compileSearchRegexbptato2024-02-171-2/+4
| | | | | | | 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 messbptato2024-02-171-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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.)
* winattrs: remove unnecessary call, fix height_px fallbackbptato2024-02-172-5/+5
| | | | no need for every new buffer to query the window size
* layout: use html/body bgcolor as canvas bgcolorbptato2024-02-171-7/+20
| | | | | | 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.)
* container: set color on double width char + tab fillersbptato2024-02-161-7/+10
|
* pager: increase numload for stdinbptato2024-02-151-0/+1
| | | | otherwise pages from stdin have a race condition in dump
* 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.
* Various refactorings & fixesbptato2024-02-143-19/+29
| | | | | | | | * disallow Stream interface usage on non-blocking PosixStreams * do not read estream of forkserver byte-by-byte (it's slow) * do not call writeData with a zero len in formdata * do not quote numbers in mailcap quoteFile * remove some unused stuff
* pager: reduce boilerplatebptato2024-02-142-35/+22
| | | | also spawn less processes in some cases

* Add pager.externFilterSourcebptato2024-02-122-6/+66
| | | | useful for filtering stuff through commands like rdrview
* Remove CLONE BufferSource; cache document sources in tmpdirbptato2024-02-123-44/+42
| | | | | | | | | | | | | | | | | | | | | | | 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.

* container: fix b/e unnecessarily switching linesbptato2024-01-201-3/+8

* Re-design word handling, add e, E, W, B, etc.bptato2024-01-191-10/+156
| | | | | | | | | | | | * Add functions for moving to the beginning/end of words (vi `b', `e'). * As it turns out, there are many possible interpretations of what a word is. Now we have a function for each reasonable interpretation, and the default settings match those of vi (and w3m in w3m.toml). (Exception: it's still broken on line boundaries... TODO) * Remove `bounds` from lineedit, it was horrible API design and mostly useless. In the future, an API similar to what pager now has could be added. * Update docs, and fix some spacing issues with symbols in the tables.
* Remove std/terminal dependencybptato2024-01-171-1/+0
