I wrote a colorizer for myself which highlights timestamp strings in the form of '2013/11/27 14:05:29 -' at the start of lines.
Leo's colorizer class was hard-coded to recognize mode definitions only in Leo's mode directory. My mode is not very general purpose and so doesn't really belong in that directory. I wanted to be able to define my mode in an @script node, so I refactored some of the colorizer code in order to make it possible. I pulled out into a separate method the part of the jeditColorizer init_mode method which didn't care about how the mode got loaded. Now my @script code can call that new method. My refactoring seems a little clumsy to me...I don't understand how all the ivars in that class are used and settled for the small change I made. Edward, feel free to polish. There is still another class which also assumes colorizer modes must have a corresponding file in the modes directory. I didn't figure out how to resolve that issue and settled for a very ugly hack of monkey-patching that method with hard-coded recognition of my mode. The c.frame.body.colorizer.isValidLanguage method is the one I monkey-patched. Anyone with ideas on how I should fix this without monkey-patching, let me know. With my latest bzr checkin, the following in an @script node works to colorize my date strings (includes the monkey-patched method). I don't recall now why I named my mode 'sol': <?xml version="1.0" encoding="utf-8"?> <!-- Created by Leo (http://leoeditor.com/leo_toc.html) --> <?xml-stylesheet ekr_test?> <leo_file xmlns:leo="http://www.leo-editor.org/2011/leo"; > <leo_header file_format="2"/> <vnodes> <v t="btheado.20131127134049.2386" a="E"><vh>sol colorizing</vh> <v t="btheado.20131127134049.2387" a="E"><vh>class sol</vh> <v t="btheado.20111207194929.3751"><vh>timestamp colorizer rules</vh></v> </v> <v t="btheado.20131127134049.2389"><vh>load rule</vh></v> </v> </vnodes> <tnodes> <t tx="btheado.20111207194929.3751">@language python # Leo colorizer control file for sol mode. # This file is in the public domain. # This mode colorizes timestamp strings like # '2011/12/04 20:31:16 -' which appear at the # start of a line properties = { } # Attributes dict for solt_main ruleset. sol_main_attributes_dict = { "default": "null", "digit_re": "", "escape": "", "highlight_digits": "false", "ignore_case": "false", "no_word_sep": "", } # Dictionary of attributes dictionaries for sol mode. attributesDictDict = { "sol_main": sol_main_attributes_dict, } # Keywords dict for sol_main ruleset. sol_main_keywords_dict = {} # Dictionary of keywords dictionaries for sol mode. keywordsDictDict = { "sol_main": sol_main_keywords_dict, } # Rules for sol_main ruleset. import leo.core.leoGlobals as g def sol_rule0(colorer, s, i): #re = r"\d{8} \d\d:\d\d:\d\d -" re = r"\d\d\d\d/?\d\d/?\d\d \d\d:\d\d:\d\d -" m = colorer.match_seq_regexp(s, i, kind="keyword2", regexp=re, at_line_start=True, at_whitespace_end=False, at_word_start=False, delegate="") return m # Rules dict for sol_main ruleset.
