* Remove unnecessary unsigned castsbptato2024-04-261-1/+1
| | | | | Unsigned operations and conversions to unsigned types always wrap/narrow without checks, so no need to manually mask/cast/etc. them.
* data: replace std/base64 with atobbptato2024-04-251-0/+63
| | | | | | | | | | std's version is known to be broken on versions we still support, and it makes no sense to use different decoders anyway. (This does introduce a bit of a dependency hell, because js/base64 depends on js/javascript which tries to bring in the entire QuickJS runtime. So we move that out into twtstr, and manually convert a Result[string, string] to DOMException in js/base64.)

* loader: remove applyHeadersbptato2024-03-121-0/+21
| | | | | | | Better compute the values we need on-demand at the call sites; this way, we can pass through content type attributes to mailcap too. (Also, remove a bug where applyResponse was called twice.)
* loader: rework process modelbptato2024-03-111-62/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* misc refactoringsbptato2024-02-271-13/+1
| | | | | | * rename buffer enums * fix isAscii for char 0x80 * remove dead code from URL
* regex: re-work compileSearchRegexbptato2024-02-171-0/+16
| | | | | | | 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.
* twtstr: misc refactoringsbptato2024-02-091-141/+24
| | | | | | * move out half width <-> full width converters * snake_case -> camelCase * improve toScreamingSnakeCase slicing
* mimetypes: simplify parseMimeTypesbptato2024-01-271-0/+6
| | | | | * use functions like until * do not call atEnd for every line, use boolean readLine instead
* Add urlenc, urldec; fix a URL encoding bug; improve trans.cgibptato2024-01-081-12/+18
| | | | | | | | | | * Fix incorrect internal definition of the fragment percent-encode set * urlenc, urldec: these are simple utility programs mainly for use with shell local CGI scripts. (Sadly the printf + xargs solution is not portable.) * Pass libexec directory as an env var to local CGI scripts * Update trans.cgi to use urldec and add an example for combining it with selections
* Use std/* imports everywherebptato2024-01-071-11/+11

* charcategory: move out isDigitAsciibptato2023-12-141-1/+1
| | | | so we do not have to import unicode
* Various fixesbptato2023-12-131-37/+0
| | | | | | | * Makefile: fix parallel build, add new binaries to install target * twtstr: split out libunicode-related stuff to luwrap * config: quote default gopher2html URL env var for unquote * adapter/: get rid of types/url dependency, use CURL url in all cases
* break up twtstr somewhatbptato2023-12-131-369/+9
| | | | | Avoid computing e.g. charwidth data for http which does not need it at all.
* twtstr: import functions from gopher2htmlbptato2023-12-121-15/+10

* css: add case-insensitive matchingbptato2023-12-111-0/+14
| | | | Also case-sensitive, but for now that is the same as normal matching...
* css: add text-transformbptato2023-12-111-3/+113
| | | | | | | Probably not fully correct, but it's a good start. Includes proprietary extension -cha-half-width, which converts full-width characters to half-width ones.
* config: better path handling; fix array parsing bugbptato2023-12-101-1/+1
| | | | | | | | | * 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.

* twtstr: remove tolower, isWhitespacebptato2023-11-201-18/+4
| | | | | | | | * tolower: strutils toLowerAscii is good enough for the cases where we need it. Also, it's easy to confuse with unicode toLower and vice versa. * isWhitespace: in AsciiWhitespace is more idiomatic. Also has a naming collision with unicode toLower.

* twtstr: remove unused functionsbptato2023-09-181-22/+0
| | | | lineedit no longer needs these
* lineedit: rewritebptato2023-09-181-0/+22
| | | | | | | | | | | | | | | | The old lineedit system worked quite well in the original synchronous model. However, because it needs access to the terminal, it has been subtly broken ever since buffer updates are allowed while the user is in line edit mode. This is best observed in incremental search, where searching for a bgcolor'ed text would result in the bgcolor bleeding into the line editor box. The new version is much simpler, and therefore less optimized. But it can still take advantage of output optimization in the terminal controller, and it is free of races (because we simply query the current state from the pager and feed it into the main output grid).

* javascript: refactorbptato2023-08-281-2/+2
| | | | | | | Split out parts of the JS module, because it was starting to confuse the compiler a little. (Peakmem is back at 750M. Interesting.)

* Fixes & workarounds to compile on Nim 2.0.0bptato2023-08-011-2/+4
| | | | | | | | | | | | | | * Import punycode, as it has been removed from stdlib. * Fix some syntax errors * Apparently you can no longer compare distinct pointers with nil. Add explicit comparisons with typeof(nil) instead. * htmlparser: rename _ to other, as semantics of _ have changed. (Quite a shame, it looked better with _. Oh well.) * Explicitly specify mm:refc, as the browser OOMs with orc for some reason. Confirmed to compile & run on 2.0.0, 1.6.14, 1.6.12, 1.6.10 and 1.6.8. (<1.6.8 it's broken & wontfix.)
