class leo.extensions.asciidoc.AbstractBlock[source]
blocknames = []
dump()[source]

Write block definition to stdout.

error(msg, cursor=None, halt=False)[source]
get_param(name, params=None)[source]

Return named processing parameter from params dictionary. If the parameter is not in params look in self.parameters.

get_subs(params=None)[source]

Return (presubs,postsubs) tuple.

is_conf_entry(param)[source]

Return True if param matches an allowed configuration file entry name.

isnext()[source]

Check if this block is next in document reader.

load(defname, entries)[source]

Update block definition from section ‘entries’ dictionary.

merge_attributes(attrs, params=[])[source]

Use the current block’s attribute list (attrs dictionary) to build a dictionary of block processing parameters (self.parameters) and tag substitution attributes (self.attributes).

1. Copy the default parameters (self.*) to self.parameters. self.parameters are used internally to render the current block. Optional params array of additional parameters.

2. Copy attrs to self.attributes. self.attributes are used for template and tag substitution in the current block.

3. If a style attribute was specified update self.parameters with the corresponding style parameters; if there are any style parameters remaining add them to self.attributes (existing attribute list entries take precedence).

4. Set named positional attributes in self.attributes if self.posattrs was specified.

5. Finally self.parameters is updated with any corresponding parameters specified in attrs.

pop_blockname()[source]

On block exits restore previous (parent) ‘blockname’ attribute or undefine it if we’re no longer inside a block.

Return True if we are not executing the system wide version i.e. the configuration is in the executable’s directory.

leo.extensions.asciidoc.lstrip_list(s)[source]

Return list with empty items from start of list removed.

leo.extensions.asciidoc.parse_attributes(attrs, dict)[source]

Update a dictionary with name/value attributes from the attrs string. The attrs string is a comma separated list of values and keyword name=value pairs. Values must preceed keywords and are named ‘1’,‘2’… The entire attributes list is named ‘0’. If keywords are specified string values must be quoted. Examples:

attrs: ‘’ dict: {}

attrs: ‘hello,world’ dict: {‘2’: ‘world’, ‘0’: ‘hello,world’, ‘1’: ‘hello’}

attrs: ‘“hello”, planet=”earth”’ dict: {‘planet’: ‘earth’, ‘0’: ‘“hello”,planet=”earth”’, ‘1’: ‘hello’}

leo.extensions.asciidoc.parse_entries(entries, dict, unquote=False, unique_values=False, allow_name_only=False, escape_delimiter=True)[source]

Parse name=value entries from from lines of text in ‘entries’ into dictionary ‘dict’. Blank lines are skipped.

leo.extensions.asciidoc.parse_entry(entry, dict=None, unquote=False, unique_values=False, allow_name_only=False, escape_delimiter=True)[source]

Parse name=value entry to dictionary ‘dict’. Return tuple (name,value) or None if illegal entry. If name= then value is set to ‘’. If name and allow_name_only=True then value is set to ‘’. If name! and allow_name_only=True then value is set to None. Leading and trailing white space is striped from ‘name’ and ‘value’. ‘name’ can contain any printable characters. If the ‘=’ delimiter character is allowed in the ‘name’ then it must be escaped with a backslash and escape_delimiter must be True. If ‘unquote’ is True leading and trailing double-quotes are stripped from ‘name’ and ‘value’. If unique_values’ is True then dictionary entries with the same value are removed before the parsed entry is added.

leo.extensions.asciidoc.parse_list(s)[source]

Parse comma separated string of Python literals. Return a tuple of of parsed values.

leo.extensions.asciidoc.parse_named_attributes(s, attrs)[source]

Update a attrs dictionary with name=”value” attributes from the s string. Returns False if invalid syntax. Example: attrs: ‘star=”sun”,planet=”earth”’ dict: {‘planet’:’earth’, ‘star’:’sun’}

leo.extensions.asciidoc.parse_options(options, allowed, errmsg)[source]

Parse comma separated string of unquoted option names and return as a tuple of valid options. ‘allowed’ is a list of allowed option values. If allowed=() then all legitimate names are allowed. ‘errmsg’ is an error message prefix if an illegal option error is thrown.

leo.extensions.asciidoc.parse_to_list(val)[source]
leo.extensions.asciidoc.re_join(relist)[source]

Join list of regular expressions re1,re2,… to single regular expression (re1)|(re2)|…

leo.extensions.asciidoc.rstrip_list(s)[source]

Return list with empty items from end of list removed.

leo.extensions.asciidoc.safe()[source]
leo.extensions.asciidoc.safe_filename(fname, parentdir)[source]

Return file name which must reside in the parent file directory. Return None if file is not safe.

leo.extensions.asciidoc.show_help(topic, f=None)[source]

Print help topic to file object f.

leo.extensions.asciidoc.strip_list(s)[source]

Return list with empty items from start and end of list removed.

leo.extensions.asciidoc.strip_quotes(s)[source]

Trim white space and, if necessary, quote characters from s.

leo.extensions.asciidoc.subs_attrs(lines, dictionary=None)[source]

Substitute ‘lines’ of text with attributes from the global document.attributes dictionary and from ‘dictionary’ (‘dictionary’ entries take precedence). Return a tuple of the substituted lines. ‘lines’ containing undefined attributes are deleted. If ‘lines’ is a string then return a string.

  • Attribute references are substituted in the following order: simple, conditional, system.
  • Attribute references inside ‘dictionary’ entry values are substituted.
leo.extensions.asciidoc.subs_quotes(text)[source]

Quoted text is marked up and the resulting text is returned.

leo.extensions.asciidoc.subs_tag(tag, dict={})[source]

Perform attribute substitution and split tag string returning start, end tag tuple (c.f. Config.tag()).

leo.extensions.asciidoc.symbolize(s)[source]

Drop non-symbol characters and convert to lowercase.

leo.extensions.asciidoc.system(name, args, is_macro=False, attrs=None)[source]

Evaluate a system attribute ({name:args}) or system block macro (name::[args]). If is_macro is True then we are processing a system block macro otherwise it’s a system attribute. The attrs dictionary is updated by the counter and set system attributes. NOTE: The include1 attribute is used internally by the include1::[] macro and is not for public use.

leo.extensions.asciidoc.time_str(t)[source]

Convert seconds since the Epoch to formatted local time string.

leo.extensions.asciidoc.update_attrs(attrs, dict)[source]

Update ‘attrs’ dictionary with parsed attributes in dictionary ‘dict’.

leo.extensions.asciidoc.usage(msg='')[source]
leo.extensions.asciidoc.userdir()[source]

Return user’s home directory or None if it is not defined.

colors Module

Colors module provides a colors names database and functions to access it.

The database is a python dictionary with reduced colornames as keys and color data in the form ‘#RRGGBB’ as values.

The reudced color names are common color names with spaces and capitalization removed.

Functions to access the data base are:

This function will convert name and return it in ‘#RRGGBB’ format if possible otherwise it will do the sme for default.

If default can not be converted, None will be returned.

name and default are reduced by removing spaces and capitalization before looking them up in the database.

This function will first call getColor to convert name (or default) to ‘#RRGGBB’ format, then it will convert this and return it as a python tuple in the form (0-255, 0-255, 0-255).

Returns None if anything goes wrong.
