Detailed Description

Main application class for the C/C++ editor backend.

This is one of the backends owned by undoApp::Editor::EditorApp. It is not registered as an ImGui panel on its own: the EditorApp routes its single "Editor" panel here when the current file is a C or C++ source or header file.

Member Function Documentation

closeFile()

void undoApp::CppApp::closeFile

(

)

Clear the editor and forget the current file.

document()

void undoApp::CppApp::document	(	std::string &	path,
		std::string &	text
	)		const

The editor's text and the file it belongs to.

getInstance()

static CppApp & undoApp::CppApp::getInstance ( )

static

Get the singleton instance of CppApp.

getLanguageLabel()

std::string undoApp::CppApp::getLanguageLabel ( const std::string &  path ) const

private

Get the language label based on file extension.

hasUnsavedChanges()

bool undoApp::CppApp::hasUnsavedChanges ( ) const

inline

Whether the text on screen differs from the file on disk.

Sticky for the same reason as the text backend's: the editor's own flag is cleared by the next Render(), and an answer that expires cannot be what a tab's unsaved mark is drawn from.

initialize()

bool undoApp::CppApp::initialize

(

)

Initialize the C/C++ editor (idempotent)

openFile()

void undoApp::CppApp::openFile

(

const std::string &

path

)

Open a file and load it into the editor.

renameFileTo()

void undoApp::CppApp::renameFileTo

(

const std::string &

path

)

Record that the file this editor holds has moved on disk.

Only the path, never the text: the editor is still showing the same file, and without this a save after a rename writes a second copy at the old path.

Parameters

path	Where the file now is

renderEditorPanel()

void undoApp::CppApp::renderEditorPanel

(

)

Render the editor inside the unified "Editor" ImGui window.

saveFile()

void undoApp::CppApp::saveFile

(

)

Write the editor's current text back to m_currentFilePath.

setDocument()

void undoApp::CppApp::setDocument	(	const std::string &	path,
		const std::string &	text
	)

Put what is on screen back into an editor, under a new file name.

The two ends of switching tabs: a backend holds one file, so several open means taking the text out before the next is loaded and putting it back when this one is shown again. The path comes separately from the text because it is where a later save goes, and re-reading it from disk would lose anything not written yet.

Parameters

path	The file the text belongs to
text	The text as it is now, unsaved changes included

setupEditor()

void undoApp::CppApp::setupEditor ( )

private

(Re)create the TextEditor widget with C++ language definition

shutdown()

void undoApp::CppApp::shutdown

(

)

Shutdown the C/C++ editor.
