Free revision control software for mac

Aqua Data Studio 8.0.2 is such an essential program which provides a database developer's complete Integrated Development Environment (IDE). The IDE provides three major areas of functionality:

• Database query and administration tool
• A Suite of compare tools for databases, source control and filesystems
• A complete and integrated source control client for Subversion (SVN) and CVS.

Major Features:

1. Database IDE: The database query and administration tools allow developers to easily create, edit, and execute SQL scripts, as well as browse and visually modify database structures. Aqua Data Studio provides an integrated database environment with a single consistent interface to all major relational databases. This allows the database administrator or developer to tackle multiple tasks simultaneously from one application.
2. Compare Tools: The suite of compare tools allows the user to easily view the differences of RDBMS servers, databases and schemas for database tasks. The tools also allow the user to view the differences of files, directory structures, source control files and full revisions.
3. Version Control: The version control client provides a complete client to Subversion and CVS repositories, allowing the user to easily manage all source control repositories within one easy to use IDE, via the Repository Browser.

ViewVC is a free and open source tool that generates templatized HTML to present navigable directory, revision, and change log listings.
ViewVC can display specific versions of files as well as diffs between those versions. Basically, ViewVC provides the bulk of the report-like functionality you expect out of your version control tool, but much more prettily than the average textual command-line program output.

Main features:
- Support for filesystem-accessible CVS and Subversion repositories.
- Support for path-based authorization, including parsing and honoring Subversion authz configuration files.
- RSS feed generation for tracking changes to repositories or individual items within repositories.
- Individually configurable virtual host support.
- Line-based annotation/blame display.
- Revision graph capabilities (via integration with CvsGraph) (CVS only).
- Syntax highlighting support.
- Bonsai-like repository query facilities.
- Template-driven output generation.
- Colorized, side-by-side differences.
- Tarball generation (by tag/branch for CVS, by revision for Subversion).
- Localization support based on the Accept-Language request header.
- Ability to run either as CGI script or as a standalone server.
- Regexp-based file searching.
- INI-like configuration file (as opposed to requiring actual code tweaks).

System requirements:
- Python 1.5.2 or later

Major Features:

Evergreen is a cross-platform GPL development environment that tries to be lightweight and language-agnostic yet functional.
Main features:
- Ubiquitous Regular Expressions - Programmers know regular expressions, and yet their graphical tools dont use make much use of them. Evergreen does. Anywhere its asking you to type something, its probably expecting a regular expression: full Perl/Java regular expressions in find, in find/replace, in find in files (as youd expect), but also in the open dialog. Evergreen uses "smart case" regular expressions, too, where an all-lowercase regular expression is assumed to be case-insensitive. You can use (?-i) and (?i) to explicitly turn case-sensitivity on and off.
- Open Files Quicker - Evergreen indexes your project, so you dont have to remember where files are. Or what case your co-worker used ("Hyperlink" or "HyperLink"?). Just a substring or regular expression that matches what you want. Evergreen updates a list of the matching files as you type (like iTunes):
- Find in Files - You can also search for files to open based on their content. Evergreen shows a tree of matches, representing the directory hierarchy. Files containing definitions are marked as such. Searching is done in parallel to take advantage of modern multi-core machines. Search results are automatically updated if anything changes:
- Find - You have a fast computer, yet the find function in other editors doesnt take full advantage of that fact. Evergreen, like less(1), highlights all the matches, whether you search with C-F or clicked on a match in the "Find in Files" dialog. Better still, Evergreen highlights all the matches as you type, so you know when youve typed enough (or too much, if you suddenly see there are no matches). Evergreen also lets you move backwards as easily as forwards through the matches: just use C-D to move backwards and C-G to move forwards, both conveniently placed around C-F, which defaults to searching for the currently-selected word. All of this comes together for fluid one-handed searching. Finally, Evergreen uses marks next to the scroll bar to give you contextual information about how many matches there are, and how theyre clustered.
- Spelling Checking for Source Code - Not only does Evergreen check your spelling as you type, it understands CamelCase words arent single-word spelling mistakes but compounds of correctly spelled words.
- Exuberant Ctags Support - Evergreen uses Exuberant Ctags (if installed) to understand the structure of your file. The symbols in the current file are shown as a tree preserving their hierarchy. You can click on an item in the tree to go to the corresponding part of the file. Conversely, as you edit, the item in the tree corresponding to the current caret position is always highlighted. The little icons tell you what kind of symbol youre dealing with. Classes, methods, and fields are circles, squares, and triangles respectively. An icons color denotes the symbols accessibility. Public, protected, private, and unknown accessibilities are shown as green, orange, red, and gray respectively. Icons for abstract classes or methods are hollow. Public static symbols are in bold. (Obviously, not all possibilities are available in all languages.)
- Bug Database Links - References to bugs in your (or others) bug databases are automatically recognized and turned into hyperlinks:
- Find/Replace - Find/replace functionality in other editors has a habit of being awkward in use. How much better to be able to see all the changes at once, with the results of the substitutions? Hovering over a match shows the captured groups in a tool tip, so you can check your capturing is as you intended.
- Workspaces - You can work on multiple projects at once, with each "workspace" getting its own tab in the overall UI. Workspaces are important. You probably want one for each project youre working on; if youre looking for "session" functionality, this is it. If a workspace looks like a project (i.e. has a Makefile or is under revision control), the files will be indexed, so you probably want the root of your workspaces to be the directories with the top-level build instructions. Theres no reason you cant create an empty Makefile as a hint to Evergreen if you want a workspaces root to be a directory that contains a collection of related projects, or it can sometimes be useful to create a simple Makefile to build all the contained projects. Evergreen doesnt look at Makefile content, so it doesnt care. Workspaces are automatically saved when you quit and restored when you restart Evergreen.
- Auto-Indent - Evergreen will automatically help you format your code in K&R, Linux kernel, or Suns Java style. If you want to manually break long lines or use an indenting style too far removed from these, youre likely to face difficulties as it continues to try to "correct" your style. Ken Arnolds thoughts on coding style explain why this is usually a counter-productive degree of freedom. What you gain from accepting Evergreens style (which shouldnt be a problem for most programmers) is that Evergreen will do most of the formatting for you. Even correcting stuff you paste in.
- Watermarks - Each document has a watermark, used to show you if youre looking at a read-only file, or a file that has been updated on disk since it was last read in.
- Building - Evergreen defers to ant(1) or make(1) to actually build your project, and will search upward from the directory containing the focused file looking for a makefile.
- Patches - If you choose a potentially destructive action such as "Revert to Saved", youre shown a colored patch and given a chance to change your mind. (Not only that, its a useful way to see how a machine-generated file is changing as you work on the generator. Just keep running the script and reverting to the latest version of the generated file.)
- "Compare Selection and Clipboard..." - Shows you a patch comparing the currently-selected text and the text on the clipboard. This is useful when youre looking at two seemingly duplicate chunks of code and want to know what, if any, differences there are between the two.
- Language awareness - Coloring and intelligent indentation of C++, Java, Perl, Ruby, and others.
- Custom text component - We gave up on JTextPane because of its poor performance, and we gave up on JTextArea because of its poor functionality. Unlike many other editors with their own text components, ours was explicitly designed to be useful elsewhere. Its interface is broadly similar to JTextArea so its easy to use in your own programs if you get used to any of the great functionality.
