Every DITA2Go configuration file must begin with at least one line of header text, even if it is an empty line. The content of the line does not matter to DITA2Go, as long as it does not duplicate the name of a configuration section.
After the header text, each configuration file contains a series of sections. Each section consists of a section name in square brackets, followed by a list of settings of the form Key=Value or Key=Command, each on a separate line; and possibly by one or more comments:
[Section] Key = Value Key = Value1 Value2 Value3 ... Key = Command ; Comment
Section names may not contain spaces or punctuation. The opening bracket for each section name must be in column 1.
Keep in mind these Microsoft rules for configuration files:
Consider all of the following:
Key names must be unique in a section
Key names are not case sensitive, by default
Fixed-key sections differ from variable-key sections
Order of settings can be important for variable keys
Multiple values are separated by spaces
Spaces and tabs: some retained, some removed
Comments start with a semicolon
Boolean values can be expressed various ways
Section names must be unique. If you use the same section name twice in your configuration file, only the first section is processed. Otherwise, order of sections does not matter, except for macro sections (see §37.1.1.2 Understanding where you can define named macros).
Key names must be unique in a section
Each Key= setting in a given section must be the only setting for that key in that section. A common error is to add a setting to a section that already has a setting for that key. For example, any repeated lines assigning additional values to the same format name are ignored; only the first line is processed. Instead, place any additional values on the same line as the first, separated by spaces.
All ASCII characters are valid in key names, with the following exceptions:
Spaces are nominally allowed in key names, but the spaces are ignored unless you turn off [Options]SpacelessMatch; see §4.1.10 Specifying how to treat cases, spaces, and wildcards. Do not use spaces if you can possibly avoid them.
Key names are not case sensitive, by default
Comparisons of key names are caseless, unless you turn on case sensitivity; see §4.1.10 Specifying how to treat cases, spaces, and wildcards. (However, when you override a configuration setting with a configuration variable, the key name is case sensitive; see §42.2.4 Assigning values to configuration variables.)
Fixed-key sections differ from variable-key sections
Configuration files contain two kinds of sections: those with fixed keys (key names predefined by DITA2Go) and those with variable keys. For example, sections such as [HTMLOptions] and [WordOptions] are for settings with fixed key names; sections such as [HTMLParaStyles] and [HelpStyles] are for settings with key names you specify, typically names of formats assigned to DITA elements.
Order of settings can be important for variable keys
In a fixed-key section, the order of settings does not matter. Order is important only in sections where you can use variable keys, and usually only if you use wildcards in key names (see §3.6 Using wildcards in configuration settings).
Often the variable-key names you specify are names of formats assigned to DITA elements, such as paragraph, character, or table formats.
Multiple values are separated by spaces
Some variable-key sections allow multiple values for each key: sections such as [HTMLParaStyles], [WordStyles], and [HelpStyles], where you can assign multiple properties to each format. Use spaces between values.
Spaces and tabs: some retained, some removed
DITA2Go treats spaces and tabs in configuration settings as follows:
Comments start with a semicolon
Lines that start with a semicolon “;” are comments. For a line to be treated as a comment, the semicolon must be the first character on the line (no leading blanks or tabs). DITA2Go pays no attention to comment lines; you can use them to add your own notes. However, do not try to “comment out” a section by inserting a “;” in front of the section name; all settings that follow such a line, up to the next line that starts with a “[”, would be added to the settings for the preceding section. To comment out a section, see §3.7 Commenting out configuration sections.
Boolean values can be expressed various ways
For an On/Off value, DITA2Go recognizes “1” (numeral one), “Yes”, and “True” as On, and “0” (zero), “No”, and “False” as Off.
