* putSaver: detect edit conflicts to prevent clobbering, if possible
if the server supplies an ETag, we send it back when saving, allowing
the server to detect edit conflicts and respond with 412 (cf.
https://www.w3.org/1999/04/Editing/)
caveats:
* this only kicks in after the first save, as we don't have access to
the ETag when first loading the document
* there's no recovery mechanism (e.g. resetting `this.etag` in order to
force clobbering), other than manually reloading the document
* putSaver: retrieve ETag upon initialization for clobbering protection
this addresses one of the caveats from the previous commit
(2d75cb83af) - while theoretically prone
to a race condition, it seems unlikely that saving will be triggered
before the server responds
* putSaver: simplify URI extraction
this simplifies the approach introduced in
f51f6bf774, with the purpose of removing
the fragment identifier
* putSaver: localize error message
* putSaver: switch to built-in HTTP helper
in the process, fixed ETag assignment in `#save` method (was
`this.etag`, now `self.etag`) as well as a syntax error due to a missing
closing brace
* putSaver: consolidate URI handling
The code here had got a bit broken by some PRs that I should have
checked more carefully. I’ve done a major refactoring which will
hopefully make it easier to understand, and fixes a number of problems:
* Problem with eg .md tiddlers not being deleted correctly
* Problem with Windows path separators not being usable within
$:/config/FileSystemPaths on Windows
* Problem with filename clashes not being detected correctly when
saving to a different directory via $:/config/FileSystemPaths
* Enables slashes within tiddler titles to be mapped into folders
* Enables plain text files like .md and .css to be saved with .meta
files instead of as .tid files (see #2558)
* No longer replaces spaces with underscores
As this is such a major update, I’d be grateful if Node.js users could
give it a careful run through — in particular, you’ll need to try
creating new tiddlers of various types and ensure that the expected
files are created.
The request handler may be used by ExpressJS apps directly and can do most of the heavy lifting without any modification. Note that the self variable must be assignee using `[Function].bind(null,SimpleServer instance)`.
* allow radio widget to set an index in a data tiddler
* updated RadioWidget docs, with same demo macro as for CheckboxWidget
in #2103
* removed docs in widget code (seems the wrong place)
* added from version to docs
* revert doc maros to master
* using wikitext-example-without-html and .tip macro now
* fix quotes
given a list `A B C D` if I run `A B C D +[move:-1 [A]]` I get `B C A D`. However, if I were to do `A B C D +[move:1[D]]` it doesn't wrap around, and I get `A B C D`. This fixes that such that `A B C D +[move:-1 [A]]` gives 'A B C D`
When renaming an existing tiddler, the edit template now shows a
checkbox that determines whether or not to relink references to the
tiddler in the list or tags fields of other tiddlers.
This fixes a problem introduced in
c7b31b0242.
The changes by @tobibeer inadvertently made the regular expression
evaluation significantly more expensive because of lookahead. The is
less elegant but reverts the performance problem.
* return all wikiparserrules w/o operand
* simpler layout & code / updated instruction details
Also wanted to link each rule to the official docs using a dictionary at
`$:/language/Docs/ParserRules/`. However, without #2194 this is not
doable.
This commit permits language plugins to carry the field
“text-direction” with the value “rtl” to trigger right-to-left layout
of the entire page. We also adjust the sidebar layout to work in RTL
mode.
There are still a number of problems to be addressed:
* Brackets and other punctuation incorrectly placed within en-GB UI text
* System tiddler titles are rendered semi-back-to-front (eg
`languages/ca-ES/:$`)
Starting to address #1845 and the discussion in #2523.
We were using `String.prototype.replace()` without addressing the
wrinkle that dollar signs in the replacement string have special
handling. This caused problems in situations where the replacement
string is derived from user input and contains dollar signs.
Fixes#2517
* Save binary tiddlers with meta file
The filesystemadaptor plugin was a little simplistic in its
understanding of a binary file. It was using the typeInfo dictionary to
choose what tiddler types were binary (and hence needed a meta file when
saving).
I looked as if it was trying to be smart by looking for the hasMetaFile
*OR* had the encoding of base64. Unfortunately the typeInfo only defined
image/jpeg and so any other base64 encoded tiddler was assumed to be of
type text/vnd.tiddlywiki.
The net effect was only JPG images got a meta file and everything else
were saved as .tid files with base64 encoding. It all still worked but
made working with binary data in a Git repo a bit daunting.
There is enough information in the $tw.config.contentTypeInfo to
determine if a tiddler type is encoded with base64 or not. A better list
is available from boot/boot.js who registers all the types thorough the
registerFileType and marks then with base64 were appropriate.
This commit uses the typeInfo dictionary first for any filesystem
specific overrides, then the contentTypeInfo, and finally defaults to
the typeInfo["text/vnd.tiddlywiki"]. It also eliminates the now
unnecessary override for image/jpeg.
I think this might have been the original intent from commit 10b192e7.
From my limited testing all files described in boot/boot.js (lines
1832-1856) with an encoding of base64 now save as the original binary
and a meta file. Meaning that when you start the node server and then
drag-n-drop a binary file (i.e. image/png) it will PUT to the server
and then save it on the filesystem as-is allowing the file to be managed
as a binary file and not a text file. (Binary diffs are better and
GitHub supports them as well).
* Prevent duplicate file extensions
A side effects of using the $tw.config.contentFileInfo in the previous
commit is that it will always append a file extension to the tiddler
title when saving. In most cases this is the correct course of action.
However, sometimes that title is already a proper filename with an
extension (for example importing 'foobar.png' would save a file named
'foobar.png.png') which seemed silly.
This commit simply checks to make sure the title does not already end
with the file extension before appending it to the filename. A little
convenience really.
Since IE apparently doesn't have the String endsWith method I took the
liberty to add a helper method to $tw.utils trying to follow the other
polyfill patterns. I figured this was more generic and readable then
attempting to use a one-off solution inline. I got the polyfill code
from MDN.
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/endsWith#Polyfill
Is strEndsWith the best method name?
