Colorer — syntax highlighting and text parsing

Post by joric »

Is it possible to override specific color when you're extending the scheme? I can override any hrc and add rules, I also can re-define regions with regular expressions, but is there a simple way to replace one color with another without changing the syntax? Maybe there's a trick I don't know?

joric, I don't know if it's possible for an individual schema or an individual color, but colors definitely can be overridden using .hrd files — please have a look at files in FarColorer's common.zip/hrd/console/ and common.zip/hrd/rgb/ and see if/how they are referenced from .hrc schemas. There's even some old documentation which I believe to be still mostly correct.

Colorer — syntax highlighting and text parsing

I created my own color scheme in this way:

1) Create a color definition file pepak.hrd. I don't quite remember how I did it, but probably I copied the default color scheme and started modifying it to my liking:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hrd PUBLIC "-//Cail Lomecb//DTD Colorer HRD take5//EN" "http://colorer.sf.net/2003/hrd.dtd">
<hrd xmlns="http://colorer.sf.net/2003/hrd">

<assign name="def:Text" fore="#b" back="#1"/>
<assign name="def:HorzCross" fore="#f" back="#0"/>
<assign name="def:VertCross" fore="#f" back="#0"/>
<assign name="def:Syntax"/>

<assign name="def:Number" fore="#b"/>
<assign name="def:NumberSuffix" fore="#b"/>

<assign name="def:String" fore="#b" back="#9"/>
<assign name="def:StringContent" fore="#f"/>
<assign name="def:StringEdge" fore="#c"/>
<assign name="def:CharacterContent" fore="#f"/>

<assign name="def:Comment" fore="#7"/>
<assign name="def:CommentContent" fore="#7"/>
<assign name="def:CommentEdge" fore="#7"/>
<assign name="def:CommentDoc" fore="#7"/>
<assign name="def:CommentDocContent" fore="#7"/>
<assign name="def:CommentDocEdge" fore="#7"/>

<assign name="def:Symbol" fore="#e"/>
<assign name="def:SymbolStrong" fore="#e"/>
<assign name="def:Prefix" fore="#b"/>

<assign name="def:Operator" fore="#b"/>

<assign name="def:Keyword" fore="#f"/>
<assign name="def:TypeKeyword" fore="#f"/>

<assign name="def:Function"/>
<assign name="def:Register"/>
<assign name="def:Constant"/>
<assign name="def:BooleanConstant"/>
<assign name="def:Var"/>
<assign name="def:VarStrong"/>
<assign name="def:Identifier"/>

<assign name="def:Directive" fore="#7"/>
<assign name="def:Parameter" fore="#7"/>

<assign name="def:Tag" fore="#b"/>
<assign name="def:OpenTag" fore="#f"/>
<assign name="def:CloseTag" fore="#f"/>

<assign name="def:Label" fore="#b"/>
<assign name="def:LabelStrong" fore="#b"/>

<assign name="def:Insertion" fore="#b"/>

<assign name="def:Error" back="#c" fore="#e"/>
<assign name="def:ErrorText" fore="#d"/>

<assign name="def:TODO" fore="#7"/>
<assign name="def:Debug" fore="#a" back="#2"/>

<assign name="def:URI" fore="#f"/>
<assign name="def:EMail" fore="#f"/>

<assign name="def:Date" fore="#b"/>
<assign name="def:Time" fore="#b"/>

<assign name="def:PairStart" fore="#d"/>
<assign name="def:PairEnd" fore="#d"/>
<assign name="def:PairStrongStart" fore="#d" back="#f"/>
<assign name="def:PairStrongEnd" fore="#d" back="#f"/>

<assign name="def:Newer" fore="#a"/>
<assign name="def:Older" fore="#b"/>
<assign name="def:Different" fore="#c"/>

<!--	<assign name="vfy:VfyOperatorMatched" fore="#c"/> -->
	<assign name="vfy:VfyOperatorAdded" fore="#a"/>
	<assign name="vfy:VfyOperatorChanged" fore="#c"/>
	<assign name="vfy:VfyOperatorDeleted" back="#c"/>
	<assign name="vfy:VfyOperatorCopied" fore="#e"/>
	<assign name="vfy:VfyOperatorRenamed" fore="#e"/>

<assign name="dirsync:DirSyncUnimportantFile" fore="#3"/>
<assign name="dirsync:DirSyncImportantFile" fore="#f" back="#3"/>
<assign name="dirsync:MissingLeft" fore="#f" />
<assign name="dirsync:MissingRight" fore="#c" />
<assign name="dirsync:OlderLeft" fore="#a" />
<assign name="dirsync:OlderRight" fore="#f" />
<assign name="dirsync:FailedLeft" back="#c" fore="#e" />
<assign name="dirsync:FailedRight" back="#c" fore="#e" />
<assign name="dirsync:FailedBoth" back="#c" fore="#e" />
<assign name="dirsync:Different" fore="#a" />

</hrd>
2) Create a scheme list file styles.xml:

Code: Select all

<?xml version="1.0" encoding="UTF-8"?>
<hrd-sets>
    <hrd class="console" name="pepak" description="Pepak">
        <location link="%FARPROFILE%\Colorer\pepak.hrd"/>
    </hrd>
</hrd-sets>
Note that you should use an absolute path here because otherwise the file locations are considered relative to the catalog file, not the styles file.

3) In Plugin Options -> FarColorer -> Main Settings, add the path to the scheme list file: %FARPROFILE%\Colorer\styles.xml

I mean if you're EXTENDING language rules. You're not overriding HRC you just fix bad mapping. It's simpler to show:

auto/python-extended.hrc:

Code: Select all

<hrc>

  <prototype name="pyExt" group="other" description="Python (extended)">
    <filename weight="5">/\.py$/i</filename>
  </prototype>

  <type name="pyExt">
    <import type="python"/>
      <!-- I can repaint numbers here as so -->
      <regexp match="/\b\d+([Ee][-+]?\d+)?([jJ])?(\w*)\b/" region0="def:NotANumber" region1="def:NumberSuffix" region2="def:Error" />

      <!-- Is it possible to remap one color (region, rather) to another color here, without copypasting the syntax rules? -->

      <inherit scheme="python">
        <virtual scheme="python" subst-scheme="pyExt"/>
      </inherit>

      <!-- I can also remap all remaining characters to symbols here -->
      <regexp match='/\w/' region0="def:Symbol"/>

  </type>
</hrc>

OK, I got it, kind of. We can use virtual schemes peeked up in "Far Colorer - Region Info" to override elements, e.g.

Code: Select all

<virtual scheme="c:Expression" subst-scheme="myCExpression"/>
It doesn't always work (not all languages use separate schemas for all the entities) but it is something.
