Fix popping subsyntaxes that end consecutively (#1246) 2022-12-27 20:24:52 -04:00
Guldoman 9d48441685
Add `regex.find_offsets`, `regex.find`, improve `regex.match` (#1232)
`regex.match` now behaves like `string.match`.
This required changes in the `tokenizer` and in the `detectindent` 
plugin.

tokenizer: remove the limit of 3 subsyntaxes depth (#1186)
* tokenizer: remove the limit of 3 subsyntaxes depth

Make the state a string of bytes instead of a 32bits integer to be able
to have deeper subsyntax support. Fixes issues with syntax files like
the one for PHP that was already hitting more than 3 subsyntaxes depth.

* remove unnecesary call to set_subsyntax_pattern_idx

* fixed wrong word on comments

Fix malformed pattern check for group patterns in tokenizer
If the token type was a simple string (and not a table), the size of the 
string was used instead of `1`.

Check if "open" pattern is escaped
Previously this check was only done for "close" patterns.

Convert more byte offsets to utf-8 pos in regex tokenizer 2022-06-12 02:55:36 +02:00

Show error if language plugin pattern has mismatching number of groups
The number of results from a pattern with groups must never be greater
than the number of token types for that pattern.

Also if a token type was undefined, it's now pushed as a `normal` one.

Fix UTF-8 matches in regex group `tokenizer` 2022-05-31 01:59:14 +02:00
Guldoman 2a41002355
Allow using regex groups to split tokens
Before, this was only supported by Lua patterns.

This expects the regex to use the same syntax used for patterns. That 
is, the token should be split by empty groups.

Force syntax patterns starting with `^` to match with the whole line
Before, syntax patterns/regexes that started with `^` didn't have the 
desired effect of matching with the start of the line.

Now those patterns are used only when matching the whole line.

Consume unmatched character correctly
We must consume the whole UTF-8 character, not just a single byte.

Correctly identify the start of the next character in `tokenizer`
When moving to the next character, we have to consider that the current 
one might be multi-byte.

replace unpack() with table.unpack()
I have no idea unpack() is still used and how it still worked.

Add PCRE to support regular expressions
Use regular expressions instead of Lua patterns for find and replace editor commands.

Syntax files can now use regex or Lua patterns as before keeping backward compatibility for plugins.

Tokenizer cleanup (#198)
* Cleaned up tokenizer to make subsyntax operations more clear.

* Explanatory comments.

* Made it so push_subsyntax could be safely called elsewhere.

* Unified terminology.

* Minor bug fix.

* State is an incredibly vaguely named variable. Changed convention to represent what it actually is.

* Also changed function name.

* Fixed bug.

rxi f5025efbb8 Moved highlighter code from `DocView` to `Doc`
* Only one highlighter state is kept per-document as opposed
  to one per-docview
* Fixes a bug with retaining older highlighter state as a
  DocView wasn't able to detect lines changing above it's viewport
* Renames `highlighter` module to more descriptive `tokenizer`
