Tabs and Indents

Use tab character
  • If this check box is selected, tab characters are used for indentation and for code reformatting.
  • When the check box is cleared, AppCode uses spaces instead of tabs.
Smart tabs An indentation consists of two parts. One part results from nesting code blocks and the other part is determined by alignment.
  • If this check box is selected, the part that results from nesting contains both tabs and spaces (if necessary), while the part defined by alignment consists only of spaces.
  • If this check box is cleared, only tabs are used. This means that after reformatting a group of spaces that fits the specified tab size is automatically replaced with a tab, which may result in breaking fine alignment.
Tab sizeIn this text box, specify the number of spaces that fits in a tab.
IndentIn this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted for each indent level.
Continuation indentIn this text box, specify the number of spaces (or tabs if the Use Tab Character check box is selected) to be inserted between the elements of an array, in expressions, method declarations, and method calls.
Keep indents on empty linesIf this check box is selected, AppCode retains indents on empty lines as if they contained some code. If the check box is cleared, AppCode deletes the tab characters and spaces on empty lines.

Other

ItemDescription
Right MarginUse these settings to specify a margin space required on the right side of an element. If you select Default option then a value of the right margin from the global settings will be used.
Wrap on typingUse these settings settings to specify how the edited text is fitted in the specified Right margin. You can select one the following options:
  • Default - in this case AppCode uses the Wrap on typing option that is specified in the global settings.
  • Yes - in this case the value in the specified right margin is used.
  • No - in this case this option is switched off and a line can exceed the number that is specified in the right margin.
Keep line breaksSelect this check box to have AppCode honor line breaks when reviewing XML files in the editor.
Keep line breaks in textSelect this check box to have AppCode honor line breaks in attributes (for example, lengthy descriptions) when reviewing XML files in the editor.
Keep blank linesIn this text box, specify the minimum number of sequential blank lines to be retained after reformatting.
Wrap attributesUse this drop-down list to determine how attribute lines should be wrapped. The available options are:
  • Do not wrap - if this option is selected, no special wrapping style is applied to the code.
  • Wrap if long - select this option to have lines going beyond the right margin wrapped with proper indentation.
  • Chop down if long - select this option to have elements in lists that go beyond the right margin wrapped to give one element per line with proper indentation.
  • Wrap always - select this option to have all elements in lists wrapped to give one element per line with proper indentation.
Wrap textSelect this check box to have long lines wrapped according to the code style settings.
Align attributesSelect this check box to have attributes in sequential lines aligned.
Keep white spacesWhen this check box is selected, the editor preserves all whitespaces within tags. The same refers also to the indents, and line breaks.
SpacesIn this area, define the usage of spaces for attributes and tag names.
  • Around "=" in attribute: select this check box to have spaces added around the "=" symbol in attributes.
  • After tag name: select this check box to have spaces added after tag names.
  • In empty tag: select this check box to have spaces added in empty tags.
CDATAIn this area, define the usage of whitespaces around and inside CDATA sections in MXML files:
  • Whitespaces around: from the drop-down list, choose how whitespaces around CDATA will be treated.
    • Preserve: all whitespaces will be left intact after reformatting.
    • Remove (keep with tags): all whitespaces around CDATA will be removed, and tags will be kept on the same lines.
    • New lines: new lines will be added before and after CDATA.
  • Keep whitespaces inside: If this check box is selected, whitespaces will be preserved after CDATA[ and before ]].

Arrangement

This tab lets you define a set of rules that rearranges your code according to your preferences.

ItemDescription
Matching rulesUse this area to define elements order as a list of rules, where every rule has a set of matches such as modifier or type.
  • new - use this button to add a rule. The empty rule area opens.
  • delete - use this button to remove the rule from the list.
  • edit1 - use this button to edit an existing rule. To see this button, navigate to the rule that you want to edit and click on the button. In pop-up window that opens, modify the rule fields.
  • arrowUp arrowDown - use these buttons to move the selected rule up or down.
Empty ruleUse this area to create a new matching rule or edit an existing one. You can select from the following filters:
  • Type - use this filter to choose classes or methods for your rule.
    Note that clicking a type keyword twice negates the condition.
  • Name - use this field to specify entry names in the rule. This filter matches only entry names, such as field names, method names, class names, etc. The filter supports regular expressions and uses a standard syntax. The match is performed against the entire name.
  • Namespace - use this field to specify the namespace in the rule. It lets you specify a rule that controls a namespace attribute position.
  • Order - use this drop-down list to select the sorting order for the rule. This option is useful when more than one element uses the same matching rule. In this case, selecting Keep order will keep the same order as was set before the rearrangement and selecting Order by Name will sort the elements with the same matching rule by their names.
  • Aliases - this option displays aliases that were defined in the Rules Alias Definition dialog. You can remove the ones you do not need.
icon sort This icon appears when you select Order by Name from the Order list. The icon indicates that the items in this rule are sorted alphabetically.
Additional SettingsUse this area to set additional arrangement options. The Force rearrange drop-down list lets you select options that affect the Rearrange entries check box in the Reformat Code dialog.
You can select from the following options:
  • Use current mode (toggled in the Reformat Code dialog) - In this case the Rearrange entries check box stays active and you can modify it in the Reformat Code dialog.
  • Always - In this case the Rearrange entries check box is selected and becomes read-only.
  • Never - In this case the Rearrange entries check box is cleared and becomes read-only.
