I'm using the ACE editor (http://ace.c9.io/) with this code:
<script src="https://cdn.jsdelivr.net/g/ace@1.2.6(min/ace.js+min/theme-cobalt.js+noconflict/mode-yaml.js)"></script>
<script>
function tuneEditor( editor )
{
editor.setTheme( "ace/theme/cobalt" );
editor.getSession().setMode( "ace/mode/yaml" );
editor.setShowPrintMargin( false );
editor.setShowInvisibles( true );
editor.setReadOnly( true );
editor.focus();
}
var contactEditor = ace.edit( "contactEditor" );
tuneEditor( contactEditor );
</script>
The YAML syntax highlighting in the ACE editor works well when coloring an unquoted key-pair, for example name: Alice.
Nevertheless, if the value is a string, but starts with a number, it colors part of the value as a number and part of it as a string, instead of interpreting that the value data-type is a string.
For example: title: 123hello would contain 123 in one color and hello in another one.
Source of truth
According to this official page: http://yaml.org/spec/1.2/spec.html#style/flow/plain:
Plain scalars must not begin with most indicators, as this would cause ambiguity with other YAML constructs.
Ie: The only restriction to the "plain scalar" (ie: non-quoted) is to not begin with "indicators" (like :, | and so on). It does not say anything about it not starting with digits.
If we look into the "indicators" section here http://yaml.org/spec/1.2/spec.html#indicator// we don't see that digits count as indicators.
Usability threat: It confuses users
This is specially ugly for sha1 identifiers and similar situations, like in this image. This confuses very much my users:
Question
- How can I make the ace editor do this syntax highlight to appear coloring only with one color the full value?
