docs synopsis: add HTML highlighing and automate manpage markup Recent synopsis changes move from literal code blocks to [RST line blocks]. This does not translate well to HTML: it's not rendered in monospace, so aligment is lost. Additionally, we don't get syntax highlighting in HTML, which adds differences to our code samples which are highlighted. We hard-wrap synopsis lines (like code blocks). To align continuation lines in manpages we need [backslashes in weird places]. Combined with the **, *, and `` markup, it's a bit hard to get the alignment right. Fix these by moving synopsis sources back to code blocks and compute HTML syntax highlighting and manpage markup with a custom Sphinx extension. The new Pygments lexer can tokenize a synopsis and assign the various highlighting roles, which closely matches fish's syntax highlighing: - command/keyword (dark blue) - parameter (light blue) - operator like and/or/not/&&/|| (cyan) - grammar metacharacter (black) For manpage output, we don't project the fish syntax highlighting but follow the markup convention in GNU's man(1): bold text type exactly as shown. italic text replace with appropriate argument. To make it easy to separate these two automatically, formalize that (italic) placeholders must be uppercase; while all lowercase text is interpreted literally (so rendered bold). This makes manpages more consistent, see string-join(1) and and(1). Implementation notes: Since we want manpage formatting but Sphinx's Pygments highlighing plugin does not support manpage output, add our custom "synopsis" directive. This directive parses differently when manpage output is specified. This means that the HTML and manpage build processes must not share a cache, because the parsed doctrees are cached. Work around this by using separate cache locations for build targets "sphinx-docs" (which creates HTML) and "sphinx-manpages". A better solution would be to only override Sphinx's ManualPageBuilder but that would take a bit more code (ideally we could override ManualPageWriter but Sphinx 4.3.2 doesn't really support that). --- Alternative solution: stick with line blocks but use roles like :command: or :option: (or custom ones). While this would make it possible to produce HTML that is consistent with code blocks (by adding a bit of CSS), the source would look uglier and is harder to maintain. (Let's say we want to add custom formatting to the [|] metacharacters in HTML. This is much easier with the proposed patch.) --- [RST line blocks]: https://docutils.sourceforge.io/docs/ref/rst/restructuredtext.html#line-blocks [backslashes in weird places]: https://github.com/fish-shell/fish-shell/pull/8626#discussion_r782837750

New -n flag for string join. (#8774) * New -n flag for string join command. This is an argument that excludes empty result items. Fixes #8351 * New documentation for string-join. The new argument --no-empty was added at string-join manpage. * New completions for the new -n flag for string join. * Remove the documentation of the new -n flag of string join0 The reason to remove this new argument in the join0 is that this flag basically doesn't make any difference in the join0. * Refactor the validation for the string join. The string join command was using the length of the argument, this commit changes the validation to use the empty function. * Revert #4b56ab452 The reason for the revert is thath the build broke on the ubuntu in the Github actions. * Revert #e72e239a1 The reason the compilation on GitHub broke is that the test was weird, it didn't even run it, Common CI systems are typically very very resource-constrained. * Resolve conflicts in the string-join.rst. * Resolve conflicts in the "string-join.rst". commit #1242d0fd7 not fixed all conflicts.

2018-12-20 04:02:45 +08:00
In general, special characters are special by default, so ``a+`` matches one or more "a"s, while ``a\+`` matches an "a" and then a "+". ``(a+)`` matches one or more "a"s in a capturing group (``(?:XXXX)`` denotes a non-capturing group). For the replacement parameter of ``replace``, ``$n`` refers to the n-th group of the match. In the match parameter, ``\n`` (e.g. ``\1``) refers back to groups.

docs/string: Add paragraph on comparison with unix tools [ci skip]

Comparison to other tools
-------------------------
Most operations ``string`` supports can also be done by external tools. Some of these include ``grep``, ``sed`` and ``cut``.
If you are familiar with these, it is useful to know how ``string`` differs from them.
In contrast to these classics, ``string`` reads input either from stdin or as arguments. ``string`` also does not deal with files, so it requires redirections to be used with them.
string docs: format options and arguments in line with other pages There are a number of items which don't fit cleanly into the styles used in the synopses, and have been left alone.

In contrast to ``grep``, ``string``'s ``match`` defaults to glob-mode, while ``replace`` defaults to literal matching. If set to regex-mode, they use PCRE regular expressions, which is comparable to ``grep``'s ``-P`` option. ``match`` defaults to printing just the match, which is like ``grep`` with ``-o`` (use **--entire** to enable grep-like behavior).

docs: use monospace for inline code snippets more consistently
2020-10-27 02:19:05 +08:00
Like ``sed``'s ``s/old/new/`` command, ``string replace`` still prints strings that don't match. ``sed``'s ``-n`` in combination with a ``/p`` modifier or command is like ``string replace -f``.
