The Word Wrap/Tab Settings branch under Configuration - Editor has the following options:
Select extension for settings or default
The editor allows the tab and Word-Wrap settings to be based on the file extension of the file. Initially the defaults will be used. To add an extension type click on Change List and a dialog will be displayed allowing you to add or edit up to 10 extension types. Users may select or add a file extension (or Default) to which all settings specified on this page will be applied. The tab and Word Wrap settings will change to reflect the extensions shown. The "default" settings are used for any files that do not match the user defined extensions. Periods must not be included when specifying extensions for word wrap settings. For example, "c cpp h" is correct, but ".c .cpp .h" is not.
If Default word wrap on for each file is selected, then word wrap will be enabled each time a file with a matching extension is opened. Please note that if additional settings are defined for other settings (aside from Default) this option would have to be selected separately for each group to which it should apply.
Auto-complete file
If desired, the path to an auto-complete file specific to the selected file extension may be specified here. Users may enter the path directly or browse to the desired file.
Use spaces in place of tabs
If this item is selected the editor will replace TAB characters with spaces and the Indent spaces value specified below will determine the number of spaces to use.
The editor allows for selection of TAB stops and for TAB characters to be replaced by spaces automatically while editing. The Tab Stop value specifies the TAB stops, while the Indent spaces specifies the number of spaces to use in place of a TAB character. This allows the user to have one setting for tabs and another for indentation.
The Indent spaces is how many spaces are used for an indent when the TAB key is used ONLY WHEN Use spaces in place of tabs is set. This applies to TAB characters entered after this setting is changed. In this case the Tab Stop value tells the editor to expand actual tab characters on the appropriate tab stop boundary. Existing TAB characters in the document are not affected by these settings.
If Use spaces in place of tabs is NOT checked, pressing the TAB key will always insert a TAB character and it will be expanded per the Tab Stop value as indicated earlier.
The user may define multiple TAB stop values (up to 12) in comma-delimited format, i.e. "4,4,8". The last value defined will be used for subsequent TABS. In the example above, the first two TABS would be equal to four spaces and all subsequent TABS would be equivalent to 8 spaces.
If the option to replace TABS with spaces is chosen under the Tabs/spaces dropdown in the Format tab, the editor inserts spaces in place of TABS but maintains the TAB stop spacing using the number of spaces specified.
Font
Users may specify a font to be used for files with the currently specified extension by pressing the Font button and selecting the desired font.
Wrap method
Word wrap may be used to automatically wrap words to the next line at the vertical edge of the active window or at a specified column.
There are four selectable modes of operation for word wrap:
Wrap at window boundary, without inserting a hard return.
Wrap at a specified column number without inserting a hard return.
Wrap at a specified column number and insert a hard return.
With this option, an additional option specifies if the file should be automatically wrapped on input. If selected, the file is wrapped on input, otherwise text is only wrapped as it is modified.
Note - The column wrap above wraps on a word boundary. This may mean that the wrap does not occur on the specified column but on a lesser column number.
Absolute wrap after specified column. This will wrap exactly at the specified column.
If the option to wrap at a specified column AND insert a hard return is made, the file is automatically modified to wrap at the column and insert appropriate hard returns.
Additionally, the Reformat Paragraph feature may be used to wrap a paragraph to the specified column number.
If the editor active window is in Hex mode this command is not available.
