# What is ci_edit
ci_edit is a text editor. It can help you view or edit text files.
ci_edit runs in the command line (also called the terminal). To start using
ci_edit, download ci_edit and open (execute) `ci.py`.## What ci_edit can do for you
Many other command line text editors require learning a different set of mouse
and keyboard commands. Many of us use a graphical editor (GUI) that supports
a common set of commands like `ctrl+q` to quit (that is, hold the control key and
press Q). Here are a few common commands:- ctrl+q to quit the program
- ctrl+s to save the file
- ctrl+z undo
- ctrl+x cut
- ctrl+c copy
- ctrl+v pasteThere are more, but you probably get the idea. These common controls are not
common in command line editors.So, what if you'd like to edit a file in the terminal window but don't want to
recall how to save or quit in an unfamiliar editor? This is where ci_edit
shines, because ci_edit does support those familiar key sequences. You already
know how to save in ci_edit, it's `ctrl+s`. Simple.This version of ci_edit still doesn't have all the intended features, but it's
a start. It's has the necessary features of a basic text editor and a few fancy
extras. Those fancy extras stay out of your way until you want them.## How to stay in touch
To get news about new features, please join
- [ci_edit-announce](https://groups.google.com/forum/#!forum/ci_edit-announce)If you have a question (i.e. "how do I..."), please post it here
- [ci_edit-users](https://groups.google.com/forum/#!forum/ci_edit-users)Have you found a case where ci_edit misbehaves, please let us know by describing
what happened here
- [Report bug in ci_edit](https://github.com/google/ci_edit/issues/new)For those interested in contributing new features or steering the future
direction of ci_edit, join us on
- [ci_edit-dev](https://groups.google.com/forum/#!forum/ci_edit-dev)### Installation (Linux / Mac OS)
* Execute the install script with root privileges. Either change directory
`cd` to the downloaded directory (or local repository): `ci_edit`, or use
the path to the installation file (i.e. `./[PATH_TO_FILE]/install.sh`).```
$ sudo ./install.sh
```* **Note:** This script creates a copy of the repository in the directory
`/opt/ci_edit/`; the **update**, overwrites that copy. Then a symbolic
link is created in the directory `/usr/local/bin/`, which is generally
designated for user programs not managed by the distribution package manager### Usage
* This command opens the text editor from any directory. The execution command
for the editor can be specified by user choice during installation or
manually.```
$ we
```* To edit a file (such as `README.md`) by name:
```
$ we README.md
```## What you can do for ci_edit
The help we now need is finding out what puts users off; what causes someone who
tries the editor to stop using it. We intend to address those issues so that
more users are happy users for a longer time.# Features of ci_edit
## Stand out features
- nested grammars
- A source file being edited may start in one grammar such as HTML and
contain nested JavaScript or CSS. ci_edit will highlight each grammar for
each separate language.
- terminal mouse support and GUI shortcuts by default (enabled out-of-the-box).
- open the file you meant
- If a given path doesn't exist, ci_edit will try to estimate "what you
meant". This allows for opening a file path by copy/pasting output from
other tools without needing to touch up the path.
- This is disabled by passing a line number parameter, such as +1 (which
opens the file to the first line).
- A path such as `a/foo/bar.cc` can open `foo/bar.cc`.
- Why: `git diff` may add `a/` or `b/` prefixes to files in diff output.
- A path such as `foo/bar.cc:421` can open `foo/bar.cc` to line number 421
- Why: some compiler or log output us a : notation to
refer to specific lines.## Uncommon features
Some other editors provide these features, but not all of them.
- file path tab-completion
- i.e. when opening files
- written in Python
- No Python experience is required. Being written in Python means that many
users will be able to review the code.
- Python 3.7+ and Python 2.7+ are supported.
- Python 2 support may be phased out in favor of focusing on Python 3
features. If you'd prefer that Python 2 support continue, please comment on
https://github.com/google/ci_edit/issues/205
- saved undo/redo
- Open a file and undo prior edits of that document
- runs on nCurses
- This means that it can use used in the terminal window just like vim,
emacs, and pine.
- sensible save and quit
- Using GUI editor keyboard short-cuts: `ctrl+s` and `ctrl+q` respectively.## Common features
We should expect these features from a text editor.
- cut/copy/paste
- Using common GUI editor keyboard short-cuts: `ctrl+x`, `ctrl+c`, and
`ctrl+v`!
- syntax highlighting
- keywords an such are displayed in different colors.
- find within text
- Regular expression search forward and backward.
- line numbers
- Shown on the left side.
- go to line with `ctrl+g`
- Jump to a line number or the top, bottom, or middle of the document
- unlimited undo/redo
- Or at least within the limits of disk space to page to
- selection modes
- select by line, word, character, select all, or rectangle (block) selection
- brace matching
- Place the cursor on a brace, bracket, or parenthesis and the pair of
characters are highlighted.
- mouse support
- Yes, in the terminal
- click to place the cursor
- double click to select by word
- triple click to select by line
- shift+click to extend selection
- alt+click for rectangular (block) selection
- pipe to editor
- Send the output from another program directly into the editor without the
need for a temporary file
- strips/trims trailing white-space on each line
- Each time the file is saved
- resume at last edit position
- The cursor location is stored within `~/.ci_edit/`
- search and replace
- Control the scope of the replacement with the current selection
- execute sub-processes
- Either with or without a sub-shell; including piping between to, from, and
between sub-processes
- filter text through other tools
- Send selected text through a sub-process and capture the output into the
current document.
- spell check
- ultra-fast spell checking. English and coding word dictionaries included.
- built-in filters
- Sort selected lines
- regex text substitution, such as s/dogs/cats/ replaces the text "dogs" with
the text "cats".## Future features (the to do list)
- bookmarks
- find in files
- Not just the current file, but search through files in a directory.
- user customizable keywords
- user customizable color scheme
- build/error tracking
- Capture the output from make and similar tools and integrate the results.
- auto reload of modified files
- Tell you when a file has changed on disk and offer to re-open it.
- trace file
- Monitor a file and continuously read in the new lines
- jump to opposing brace
- Move the cursor from here to there.
- a lot more...
- There are so many dreams for the future.# Obligatory
## Origins
The world does need another text editor. (Or at least I think so).
There are other fine curses based editors. I found that I was often trying to
tweak them to get just what I wanted. Almost as often, some aspect of those
editors prevented that last little bit of customization. So writing a text
editor should allow all the customization I like, right?Writing a text editor is an interesting project. Give it a try sometime.
