I've looked for a while, and it seems that there is no easy way to do
this, not even in bash, and worse with /bin/sh. So this is kind of
resorting to a simple parsing of the input, and using `eval' if it
starts with a tilde. Note the hack of not doing that when there is a
space, otherwise the `eval' thing will silently ignore it.
This hack means that it's easy to get into a mess if quotes are used
after a tilde, but that was already the case with the use of `eval' to
handle environment variables. It's not a real security issue, however,
since we're talking about a user who can just run any command anyway.
Also including a test file for the expansion functionality. If anyone
wants to improve this code, making the tests pass would reveal the
tricky issues.
[FWIW, I've asked on the #bash channel, and the only serious suggestion
was getting the paths as command-line arguments. This will, however,
defeat the point of being newbie friendly...]
Closes PR 12893.
The following packages were removed:
- combinator-parser
(see `asumu/combinator-parser` on PLaneT)
- tex2page
(see `asumu/tex2page` on PLaneT)
- test-box-recovery
The examples make up the majority of the front page, and it turns out
that google used some of these links in "sitelinks" in search result.
These links should be the main entry points, and we ended up having such
gems as "Printf" be there. They provide a way to "demote" URLS so they
won't show there, but doing that for one link means that another will
pop in (and there's a limit of a 100 such demotions). So add this in an
attempt to make it not consider them as things that can be used in the
sitelinks. This might be reverted if it doesn't help.
(Note that this is discouraged as a way to "sculpt pagerank", but the
purpose here is not to affect how they crawl the web pages and make page
reputation flow, but only to cover up for a missing feature that ends up
with horrible sitelinks. The pages are scanned anyway from the doc
pages.)
* The main page's title appears in search results, so use "The Racket
Language" instead of "Racket". Additional minor tweaks to a few more
titles to make them presentable as search results.
* Add a `#:description' keyword to make it easy to add it to pages. Add
such texts to the main page, downloads, community, learning, people,
and mailing list pages.
* Add a <meta name="robots" content="NOODP" /> to the front page, to
avoid getting the ODP (dmoz) blurb, hopefully the new and improved
description(s) will be used instead. (If not, this should be
reverted.)
