* term: fix coloring messbptato2024-02-171-29/+171
| | | | | | | | | | | | | | | | | | | | | | | | | 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.)
* layout: use html/body bgcolor as canvas bgcolorbptato2024-02-171-6/+7
| | | | | | 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.)
* Remove newFormatbptato2024-01-231-3/+3
| | | | Pointless; it just returned a default zero-initialized object.
* Remove std/terminal dependencybptato2024-01-171-14/+30
| | | | It is mostly unnecessary, and conflicts with our use of termcap anyway.
* Use std/* imports everywherebptato2024-01-071-9/+9

* Compile with styleCheck:usagesbptato2023-12-281-5/+5
| | | | much better
* break up twtstr somewhatbptato2023-12-131-0/+1
| | | | | Avoid computing e.g. charwidth data for http which does not need it at all.
* pager, container: add text selection/copyingbptato2023-12-031-3/+12
| | | | | | | | | | * 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 `\'
* pager: fix regressionbptato2023-11-211-2/+2
| | | | | pager.tty refers to infile, not outfile. rename to avoid further confusion
* bindings: find termcap on FreeBSDbptato2023-11-211-8/+8
| | | | | pkg-config does not find termcap (or really, ncurses) here, so we have to find it ourselves.
* pager: remove pager.tty memberbptato2023-11-211-4/+5
| | | | now it's a function

* move around more modulesbptato2023-09-141-3/+3
| | | | | | | | | | * ips -> io/ * loader related stuff -> loader/ * tempfile -> extern/ * buffer, forkserver -> server/ * lineedit, window -> display/ * cell -> types/ * opt -> types/
* add extern, refactor some term functionsbptato2023-09-091-47/+54
| | | | | | | | | | | * 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.
* Move charsets into chakasubptato2023-08-141-2/+3

Editing is implemented using an external editor (like vi).
