* man: better error handlingbptato2024-03-171-35/+89
| | | | | | The "redirect stderr to stdout" scheme broke with groff/man-db, as it was spitting out warnings during execution. So now we handle stderr and stdout separately.
* data: content type fixesbptato2024-03-151-7/+5
| | | | | | | * do not skip first 5 chars (this is legacy from when we used query strings) * allow practically anything but control chars (so we can use parameters)
* man: improve header/footer conversionbptato2024-03-151-4/+11
| | | | | | | * run processBackspace on the first line, because groff likes to print formatting there too * check man references like SAMEPAGE(1) with isCommand because it's commonly found in footers
* man: work around parameter insanitybptato2024-03-151-6/+18
| | | | | | | | | | | | | | | | | | | | | This is horrible. -s means completely different things on various systems. -l does not exist on various systems. Nothing is standardized, except that man should take at least one parameter and that -k should perform a search. (Seriously, that's all.) So what we do is: * add a separate env var for overriding apropos * for man:, never use -s to specify sections * for man-k:, fall back to man, EXCEPT on FreeBSD which does not have a working section specifier on man -k (neither -S nor MANSECT does anything) * for man-l:, just pass the path wholesale to man and hope it does something useful. Also, we now set MANCOLOR to 1 so FreeBSD man gives us formatting as well.
* man: misc improvementsbptato2024-03-141-59/+71
| | | | | | | * do not use query string for arguments * accept symlinks as man binaries * improve error message reporting * run all regexes on the original line
* man: rewrite in Nimbptato2024-03-132-258/+308
| | | | | | | | | | | | Depending on Perl just for this is silly. Now we use libregexp for filtering basically the same things as w3mman2html did. This required another patch to QuickJS to avoid pulling in the entire JS engine, but in return, we can now run regexes without a dummy JS context global variable. Also, man.nim now tries to find a man command on the system even if it's not in /usr/bin/man.
* mancha: only set man as section without other parametersbptato2024-03-121-1/+2
| | | | e.g. `man 2 -k blah' should not override the section

* loader: rework process modelbptato2024-03-112-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* http: do not use buffered stdiobptato2024-03-021-6/+9
| | | | | | | buffering output kind of defeats the purpose of the entire loader select machinery (we don't buffer streams either for the same reason)
* loader: clean up regular file loadingbptato2024-02-261-4/+1
| | | | | | | | | | | | | | | | | | | | * Get rid of sostream hack This is no longer needed, and was in fact causing loadStream to get stuck with redirects on regular files (i.e. the common case of receiving <file on stdin without a -T content type override). * Unify loading from cache and stdin regular file code paths Until now, loadFromCache was completely sync. This is not a huge problem, but it's better to make it async *and* not have two separate procedures for reading regular files. (In fact, loadFromCache had *another* bug related to its output fd not being added to outputMap.) * Extra: remove ansi2html select error handling It was broken, because it didn't handle read events before the error. Also unnecessary, since recvData breaks from the loop on n == 0.

* Separate ANSI text decoding from main binarybptato2024-02-251-0/+380
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
