The following are possible bugs or unintended backwards-compatibility breaks that have been reported for Twine 1.4.0.

Sugarcane sidebar

The Sugarcane sidebar's CSS is missing “left:7.5em”, thus placing it too far to the left of the screen.

Makeshift patch

Put this CSS code in a stylesheet passage: #sidebar { left:7.5em; }

The syntax highlighting for external links is broken - all external links are displayed as bad links even if they begin with “http://”.

Variable array indexes

Due to a bug, you currently can't use variables as array indexes (such as $weapons[$hand]) unless you include extra padding whitespace.

Makeshift patch

Put a space between the array variable and the first square bracket: $weapons [$hand]

<<choice>>

«choice» ought to disable both itself and every other «choice» macro in the passage - but in 1.4.0 it only disables itself.

Shorthand <<display>>

The shorthand <<display>> syntax sometimes gives a nonsensical error if no arguments are given - for instance, «Start» doesn't work.

Makeshift patch

Put a space between the passage's name and the ending »: «Start »

<<nobr>> errors

Due to a bug, «nobr» produces an error message if any text at all follows the closing «endnobr» tag, including whitespace. It also doesn't allow nesting «nobr» tags (but admittedly, that's not really useful at all).

Makeshift patch

Use the \ line-continuation symbol in place of «nobr» in situations where this would be an issue.

<<textinput>>

This macro's absence is not actually a bug. «textinput», a macro that was added in the Twine 1.3.6 alpha, was removed from the Twine codebase by its author, as it was intended primarily for testing and was never meant for actual end-use. (In Twine 1.4.1, it may be possible to use raw HTML <input> tags to replicate the original functionality of «textinput», with the advantage of allowing more input types than just text boxes.)

Makeshift patch

You can re-insert «textinput» by including this script:

macros.textinput={handler:function(a,b,c){if(c[1]){var d=c[0].replace(/\$/g,"");el=document.createElement("span");var e="<input id='"+d+"' type='text' onkeypress=\"var charCode; if(event && event.which){charCode = event.which;}else if(window.event){event = window.event;charCode = event.keyCode;}if(charCode == 13) {state.history[0].variables."+d+" = this.value; state.display('"+c[1]+"')}\"/>";if(c[2]){e+="<input type='button' value='"+c[2]+"' onclick=\"state.history[0].variables."+d+" = getElementById('"+d+"').value; state.display('"+c[1]+"');\"/>"}el.innerHTML=e;a.appendChild(el)}else{throwError(a,'"[PassageName]" parameter missing')}}};

<<return>> and bookmarks

Just as in 1.3.5, the «back» macro may not function correctly for game states loaded from a bookmark. If you bookmark a passage that contains a «back» macro, then reload from the bookmark, the «back» macro won't work because the loaded page is the only page in the browser history. However, the «return» macro also suffers from this deficiency, for reasons

Makeshift patch

Use [[Return|previous()]] instead of «return».

Scripts

Some old scripts, such as Leon Arnott's Tag CSS, contain a shim to get them to work with the Start passage in Twine 1.3.5, by using the state.history object. Unfortunately, the script (and presumably others like it) does not correctly check for the existence of state.history[0].passage, so it will crash in Twine 1.4. (If you are getting the error message state.history[0].passage is null or something similar, this is likely the reason.) Due to the popularity of this and other scripts, a counter-shim may be installed in Twine 1.4.1 to counteract this.

Strictly speaking, none of the 'monkey patch' Twine 1.3.5 scripts (which can be taken to mean “those that don't add new macros”) are officially supported by Twine 1.4 - since they directly replace key engine functions like History.prototype.display, they will likely eliminate new 1.4 engine features and replace them with inferior 1.3.5 features.

Recommendation

If you're using any of these scripts (which includes Tag CSS), you should delete them from your projects, as their functionality is present in Twine 1.4 out-of-the-box.
