html-indenting-rules: preference variable

Default value: 0xffffff

This variable controls whether Epsilon uses smart indenting for HTML or XML (or scripting embedded within it), or just copies indentation from the previous line. Bits in the variable enable smart indenting for various languages, as shown below.

Scripting Language   Smart Indent

JavaScript   0x1

VBScript   0x2

PHP   0x4

Python   0x8

CSS   0x10

These bits enable indenting in certain contexts:

0x100: permits indenting inside tags.
0x200: permits indenting for text lines that don't start with a tag.
0x400: permit indenting the first line of a script block, but only when its opening < is indented. When the < is at the left margin, the script will start there too.
0x800: permit indenting the first line of a script block unconditionally, overriding 0x400.

Also see the html-auto-indent and xml-auto-indent variables, which control whether and how Epsilon indents when you press <Enter> (not <Tab> or other keys that indent).

By default smart indenting is enabled in all cases.

When there are multiple start tags on a single line, Epsilon normally indents the next line by one level no matter how many start tags appear. Turning off the 0x80 bit tells Epsilon to indent more in such cases, as if the start tags had appeared on separate lines.

The 0x8000 bit controls how Epsilon indents when the attributes of a tag continue onto the next line. This bit makes Epsilon align the equal signs following each attribute. Turn it off if you want Epsilon to align the attribute names instead.

When you press certain keys like {, :, #, or a right delimiter, Epsilon normally reindents that line when in scripting. These bits in html-indenting-rules enable such reindenting:

Scripting Language   Enable Reindent

JavaScript   0x10000

VBScript   0x20000

PHP   0x40000

Python   0x80000

CSS   0x100000

Note that you can type expressions at the set-variable prompt, like varname | 0x100 to set a bit in the variable varname you're setting, or varname & ~0x100 to turn it off.
