Languide manual

Languide provides high-level editing commands, such as turning an in-line block of code into a procedure, and substituting a call to the procedure for the original code. Languide is one of a pair of companion packages. The other one, Versor, provides flexible keybindings which can be used to navigate code in terms of its structure. Part of Versor's functionality is provided by the lower-level parts of Languide. See Versor and Languide (Versor: versatile cursors for GNUemacs), for more information. Most of Languide's functionality can be, and normally would be, accessed through Versor, but it is possible to use Languide commands directly. This manual describes the direct use of them; for use through Versor, See Top (versor).

• Introduction: What it's all about
• Concepts: Languide works at a more abstract level than most editor commands. Its commands will probably make more sense if you understand the abstractions it uses.
• Commands: Things Languide can do
• Setup: How to install and configure Languide
• Extension: How to define languages and statements
• Languide and Versor: Interface to a companion package providing easy access to commands
• Command Index: Command Index
• Concept Index: Concept Index --- The Detailed Node Listing --- Commands
• Alterations: Altering the selection
• Expression handling: Expression handling, expressions, and functions
• Statement handling: Statement handling Expression handling, expressions, and functions
• Employ variable: Employ variable Given an existing variable definition, this finds any existing use of that value, and substitutes the variable.
• Convert to variable: Convert region to variable Given a region containing an expression, this sets up a variable initialised to that expression, and replaces the original expression with that variable.
• Convert to function: Convert region to function This takes the selected region, defines a new function just before the one containing the region, and replaces the original region with a call to the new function.
• Surround with call: Surround region with call This wraps the current region with a call to a function.
• Remove call: Remove surrounding call This removes the function call surrounding point. Statement handling
• Unify Statements: Unify Statements This makes the selected region into a compound statement.
• Make conditional: Make the selected code conditional
• Make repeating: Make the selected code iterative
• Scoping point: Move to enclosing scoping point This moves point to the most nearly enclosing scoping point, that is, a suitable place for putting new variables.
• Decision point: Move to enclosing decision point This moves point to the most nearly enclosing decision point, that is, a suitable place for putting a new condition. Setup
• Configuration: Configuring Languide Configuration
• Auto-edit overlay face: How to draw attention to changes away from point
• Whole statement as container: On selecting a container, whether to make that the whole statement
• Cyclic: Whether statement part selection should be cyclic
• IncludeContainer: Whether statement containers count as selectable statement parts
