Speare is an ultra lightweight code editor and small IDE. It was originally developed to providing a native scripting language debugging environment that seamlessly integrated with C and C++, and with an efficient code navigation and call routines tracing ability. Speare has very simple interface that allows end user to add a new programming language code runner, parser, syntax highlighting, code formatter and debugger to it. You can use the free version to debug C and C++ project. Speare Pro is the advanced version that supports debugging with more programming languages including Ruby, Lua, Python, PHP, Perl and Tcl. Most of the debuggers supports extending themselves in source code level and directly switch between any version of self-compiled scripting language interpreters.

Code editor and IDE on macOS
Terminal based on text editors such as GNU Emacs and Vim, although they are very cool, but their limitations are also obvious, the elephant in the room. TextMate is my favourite code editor long years ago and until today, but it still lack some features. As a programmer, so many IDE and text editors I've used in the past years, such as the bulky cargos, Visual Studio Code, Atom, Android Studio, Eclipse, ActiveState Komodo, Xcode, and some light cargos, e.g. Textadept, CotEditor and TextMate. I never like the bulky cargos, e.g. desktop applications that built with NodeJS, React and Electron, Eclipse and Java or .NET and C# based big stuffs. Speare code editor is a small, free and friendly code editor which implements the most important missing features in common code editors, e.g. bookmark and fast locate code lines between multiple files, code block live parsing etc.

Why not big software?
Waste time to maintain, wast big storage and runtime memory, waste power, waste time to upload and download. It's waste people's life! Every desktop developer should known one thing, the embedded system developers sometime even fighting for one byte of storage in some situation. They never think about memory and storage like embedded system developers, so more and more big monster there. In today's software industry, Unix philosophy has been throw away completely!
They make software as big as possible, as complex as possible, but I believe in the opposite philosophy.

Refresh Symbol List or Bookmark (Breakpoint) List
Click toolbar "Functions": function definitions of current file will be re-parsed and represented in left side Treeview.
Click toolbar "Breakpoints": all breakpoint (bookmark) of current file will be re-loaded in the left side Treeview.
Type in class name, function name, or variable name or anything else, wait one to three seconds and use Up and Down arrow key to move selection in the candidates and click "Return" key to select one.
SPP File is the abbreviation of "Speare Project Plist" file, it is the project file type of Speare that has an .spp file extension, it packs variant of project meta information together, including project folder and its bookmark/breakpoints, watches, opened tabs, selection of each tab, current selected tab etc.
- Create SPP File
Click menu: File → Save as Speare Project file. This operation will store the root path of the nodes in the left side Treeview as a .spp file.
- Open SPP File
Directly dragging the .spp file into Treeview, or select menu "File" → "Open", will load all indexed file and folder stored in the .spp file into the left side Treeview (Workspace Explorer).
When switch to another project, it is necessarily required to save current project so that the project meta information stored in .spp file and can be restore later otherwise these information will lost!
Search and Replace
- Search Current Document:
a. Use the shortcut key "Control + F" to do the searching just like in TextEdit.
b. Click search button on the toolbar and on the prompt dialog select "Current File".
- Search Current Folder:
Click search button on the toolbar and on the prompt dialog select "Current Folder".
- Search Opened Files:
Click search button on the toolbar and on the prompt dialog select "In Opened Tabs".
- Search Entire Project Folders:
Click search button on the toolbar and on the prompt dialog select "In Entire Project".
- Searching by Index:
a. Click symbol button on the toolbar and select items that parsed by the build-in syntax parsers.
b. Click breakpoint button on the toolbar and select items that placed as bookmark or breakpoint.
- Searching items in left side Treeview:
Input the item name (or prefix or suffix, or contained word) in the search field which located in the bottom of the left side Treeview and then enter "Return" key, click up and down arrow right side of the search field to iterate items.
Tab Selection and Dragging
Speare use tabs to manage multiple opened files on the right side, continuously click on the leftmost or rightmost tab can quickly scroll tabs to left side or right side so that opened files can be quickly switched. Dragging special tabs together will also can help simultaneously editing multiple files.
Tips: click tab can fast select the node of left side Treeview when it loaded or reloaded end.
File Rename and Save
1. File Rename
Click the item in the left side Treeview and input a new file name just like in Finder, and then click the left side icon to end editing.
2. File Save
Speare can save file automatically whenever it be edited but the temporary "Untitled files" will be asked to save when quit the app or load a .spp file, because load a .spp file will empty current Treeview.
In addition, Speare will change the icon colour of the item in the left side Treeview to indicate that it has been edited whenever it be edited, and will restore to default state when click the "Save" or "Save All" button on the toolbar.
Jump To Definition
Ensure the keyword selected and then right click one of the popup menu items. Speare provides all location where the symbol defined including header file and implement file.
Bookmark & Breakpoint
1. Add: click the line number.
2. Toggle: click on the marker, its colour will changed to dark or light, dark colour means breakpoint in debug mode.
3. Delete: right click on the marker → on the prompt menu, select "Remove".
Show in Finder

Insert full path of current file
a. Click menu: File → Insert Full Path.
b. Use shortcut key "Option + Shift + I" to do the work.
Back and Forward
Just click the "Back" or "Forward" button on the toolbar to switch different edited location in a same file or switch between the files that was being editing.
File OverWrite and Refresh
When you overwrite a file in Finder, Speare will ask you to reload it, you should save this file manually if you click "Cancel". You can also click the "Refresh" button on the bottom of the left site TreeView to reload the entire project, it may take a while to complete the loading for big project. When you overwrite, rename, add or delete a file or folder in Finder, please right click its parent folder in the left side TreeView and click "Reload" on the popup menu.
Right click current editing file → select "Colour Picker" on the prompt menu, then a HTML colour will be inserted when pick a colour.
Customise Font and Colour
Click menu item "Preferences" and then set font and colour of editor background etc.
Add a new colour scheme:
Put you customised colour scheme in the following directory:
Please create the directory if it is not exists.
Markdown & HTML
1. Preview: select menu "View" → "Preview", see html or markdown file rendered in builtin web browser instantly.
2. Close Preview: select menu "View" → "Close Preview", close the opened builtin web browser.
3. Save Markdown: select menu "View" → "Save Markdown", save the generated html to local file, Speare has a builtin converter that can convert markdown to html instantly.
Note: a. supported file extensions: .htm, .html, .md, .mdown, .markdown.
b. click any file item in the left side Treeview will also close preview automatically.
a. C, C++, Objective‑C, C#, Java (builtin support).
(located in the formatters directory, and requires some modification to correctly working.)
Location of formatters:
If the formatters has not installed, in the prompt dialog, select subfolder "com.sevenuc.SpeareHelper" and then click "Install Code Formatters" button. This directory contains various code formatter (aka. code beautifier) that used to indent and format code block for Speare code editor.
The rule of formatter is:
Speare code editor will give up formatted code block if there's something printed in stderr or nothing printed in stdout otherwise anything printed in stdout will be used to replace the selected code block.
Ensure the formatters correctly working, you should take a look at above directory, especially modify the shell script to match the path of executables (install interpreter or missing component), including:
Note: The selected code block is complete or has logical begin and end border then the formatter can generate better output.
Click siding button on toolbar and click menu "View → Hide Toolbar" then the app can be changed to an TextEdit-like editor.
Speare Pro seamlessly support debugging C, C++, Ruby, mruby, Lua, Python, PHP, Perl and Tcl script, more info see here: → Speare debugger architecture.
File and Folder Filter
1. Click menu: View → Don't Show Hidden Files. Hide or display all hidden files.
2. Speare code editor uses a file named as
prefix+*/ (ignore directory name with prefix)
*+suffix/ (ignore directory name with suffix)
*+word+*/ (ignore directory name contains word)
# 2. exclude directories by full path (
# 3. exclude files by specified extension.
# 4. exclude files by file name.
.DS_Store (already ignored by builtin function)
prefix+* (ignore file name with prefix)
*+suffix (ignore file name with suffix)
*+word+* (ignore file name contains word)
# 5. exclude files by full path.
a. Line starts with '#' is comment.
b. Each line contains a match rule to ignore directory or file.
3. Create or edit
a. The ignored directory and files will not be parsed and their symbol definitions will not be indexed in background.
b. When overwrite file or folder in Finder, they will not be asked to reload if they were set to be ignored (deprecated).
c. You can directly edit file .speareignore in Speare code editor and click the "Refresh" button on the bottom of the left site TreeView to reload the project folder.
Warning: File system monitor have been removed from version 1.2.38, please right click the particular folder to "Reload" it or click the "Refresh" button to reload the entire project.
About MATLAB source code
Please convert file extension name from .m to .mat to prevent conflict with objective-c files, to accomplish that, please download a simple perl script from here: rename.pl (2KB), and execute:
About Dart programming language
Speare code editor uses extra component to parse and index Dart source code and format code block, please download the parser from here: dart_parser.tar.gz (2.8MB), and following readme.txt in it to configure it to working with the editor.
Add a New Programming Language
Download the guide from here: language_extension_protocol.pdf, and following the description to add a new programming language code runner, parser, syntax highlighting, code formatter and debugger in Speare code editor.
Instant Syntax Checking and Run Code Snippets
a. Press shortcut key "Command + R".
b. Click menu: File → Run External Command.
Location of the shell scripts for the external commands:
This is a common interface that enables end user to run code for various of tasks immediately, usually includes syntax checking, unit test, and run code snippets.
You can put different of shell scripts in this directory to instantly run other tasks, such as automatic compile, building and packing, or run static code analysis tool (source code analyzer, such as PC-Lint, clang-analyzer, PHPLint etc), and any other tasks. Speare code editor determine which shell script should be called by the extension name of the source code files. One shell script service for one programming language. Every script can accept two input parameters, the full path of the current selected file and the selected code block, and the last parameter is optional and can be empty string.
#!/bin/bash # $1 is the path of the current selected file # $2 is the selected code block (optional) ruby $1
The above is a sample shell script that accepts a file as input parameter and run it, if there's some syntax error, the error message will be printed in the debug output (the black area on bottom right ). Please execute "chmod +x" to ensure the script is executable. Speare code editor will merge stderr and stdout together and print them in the debug output.
The map between the source code file extension names and the entry shell script name:
c.sh: *.c cc.sh: *.cc, *.cxx, *.cpp, *.c++ ruby.sh: *.rb lua.sh: *.lua python.sh: *.py perl.sh: *.pl php.sh: *.php tcl.sh: *.tcl js.sh: *.js sh.sh: *.sh (shell script) go.sh: *.go rust.sh: *.rs dart.sh: *.dart
TO add a new programming language and associate its source code file extension names with an entry shell script, please refer this document: language_extension_protocol.pdf.
Note: Don't use this approach to run long running tasks but should launch Terminal.app to do such works.
1. Use ESC key or arrow key or 'Control+Z' to get out of suggested words list selection.
2. Please ensure all source code file and resource files have been dragged in the left side Treeview (Workspace Explorer) before start a debug session, because macOS app can't be allowed to access files outside of its sandbox.
3. When your source code file moved to another folder, you must drag the source code folder in Speare again then the debugging can correctly work.
