Member Function Documentation

DoLoopFooter()

std::string LuaLanguage::DoLoopFooter ( bool  before_expr )

virtual

The Lua parts of a do-loop footer.

Parameters

[in]

before_expr

True to fetch the initial part of the footer, false for the ending part.

Returns

"until (" if before_expr is true, ")" if not.

DoLoopHeader()

const std::string LuaLanguage::DoLoopHeader ( )

virtual

The Lua "repeat" keyword.

Returns

"repeat".

Else()

const std::string LuaLanguage::Else ( )

virtual

The Lua "else" keyword.

Returns

"else".

EndBlock()

std::string LuaLanguage::EndBlock ( CONTEXT  context )

virtual

A Lua block ender.

Parameters

[in]

context

The current context.

Returns

"end", unles the current context is {

See also

TO_ELSE_BLOCK}, in which case it will return an empty string, because "end" is not needed before an else.

FunctionCallArgumentSeperator()

const std::string LuaLanguage::FunctionCallArgumentSeperator ( )

virtual

The Lua argument separator.

Returns

",".

FunctionCallBegin()

const std::string LuaLanguage::FunctionCallBegin ( )

virtual

The Lua function argument list opener.

Returns

"(".

FunctionCallEnd()

const std::string LuaLanguage::FunctionCallEnd ( )

virtual

The Lua function argument list closer.

Returns

")".

Goto()

std::string LuaLanguage::Goto ( uint32  target )

virtual

A Lua "goto" instruction.

Parameters

[in]

target

A memory address label.

Returns

"goto label_0x<target>X".

If()

std::string LuaLanguage::If ( bool  before_expr )

virtual

The Lua parts of a if control sentence.

Parameters

[in]

before_expr

True to fetch the initial part of the sentence, false for the ending part.

Returns

"if (" if before_expr is true, ") then" if not.

Label()

std::string LuaLanguage::Label ( uint32  addr )

virtual

Generates a Lua label to use with goto.

Parameters

[in]

addr

Target address label.

Returns

"::label_0x<target>X::"

LineTerminator()

const std::string LuaLanguage::LineTerminator ( )

virtual

The Lua line terminator (none).

Returns

An empty string.

LoopBreak()

const std::string LuaLanguage::LoopBreak ( )

virtual

The Lua "break" keyword.

Returns

"break".

LoopContinue()

const std::string LuaLanguage::LoopContinue ( )

virtual

The Lua "continue" keyword.

Continue is not implemented in Lua.

Returns

A commented string.

StartBlock()

std::string LuaLanguage::StartBlock ( CONTEXT  context )

virtual

The Lua block starter (none).

Parameters

[in]

context

Unused.

Returns

An empty string.

WhileHeader()

std::string LuaLanguage::WhileHeader ( bool  before_expr )

virtual

The Lua parts of a while control sentence.

Parameters

[in]

before_expr

True to fetch the initial part of the sentence, false for the ending part.

Returns

"while (" if before_expr is true, ") do" if not.
