* Separate ANSI text decoding from main binarybptato2024-02-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove CLONE BufferSource; cache document sources in tmpdirbptato2024-02-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | 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.

* config: better path handling; fix array parsing bugbptato2023-12-101-2/+2
| | | | | | | | | * 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, container: add text selection/copyingbptato2023-12-031-1/+13
| | | | | | | | | | * 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 `\'
* loader: add local-cgibptato2023-09-301-0/+17
| | | | | | | | | | | 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

* add extern, refactor some term functionsbptato2023-09-092-0/+86
* Add an extern() call. Maybe it should be defined on client. It certainly should accept a dictionary instead of the enum type we use now. Perhaps it should return the error code? I'll leave it undocumented until I figure this out. * Refactor enableRawMode, unblockStdin, etc. so that they operate on the term object instead of global state. * Move editor to a separate folder, and factor out runprocess into a different module.
