Introduction

Xtdmacs provides a bunch a development tools and ready-to-use configuration. Each feature is bundled as a separate minor mode.

Install

Xtdmacs depends on yaml-path which is not yet included as MELPA package and should be installed manually following instructions.

The following procedure downloads latest package version and install xtdmacs and all its dependencies in your elpa directory, usually ~/.emacs.d/elpa.

tag=$(curl -s https://api.github.com/repos/psycofdj/xtdmacs/tags | jq -r '[ .[] | .["name"] ] | sort | last')
wget https://github.com/psycofdj/xtdmacs/archive/${tag}.tar.gz -O xtdmacs-${tag}.tar.gz
tar xvzf xtdmacs-${tag}.tar.gz
cd xtdmacs-${tag}
make install

Loading modes

Each mode provided by xtdmacs can be loaded like every other minor mode. However we recommend to use the xtdmacs-loader described below.

• Manually

  Example: M-x xtdmacs-bindings-mode RET

• From ~/.emacs

  Example: (xtdmacs-bindings-mode)

• Using customization

  M-x customize-variable RET xtdmacs-bindings-mode RET

• Using xtdmacs's loader

  xtdmacs-loader package provides its own minor-mode loading system. It is very similar to default minor-mode-alist but allows to define the same mode list to several file extensions.

  This package helps customizing which minors modes should be loaded for each file extensions.

  In order modify associations between file extensions are minor modes, the easiest is to run the following command:

  • M-x customize-variable RET xtdmacs-loader-auto-minor-mode-alist RET

  

  To enable xtdmacs-loader, you need to load package at start up :

  ;; in your ~/.emacs
  (require 'xtdmacs-loader)

General purpose modes

Bindings

xtdmacs-bindings setup keyboard bindings for the most commonly used features.

The ido mode provides an efficient way to navigate among opened buffers. Ido display available buffer names in mini-buffer and filters the list as you type characters.

It defines functions to directly cycle among existing buffers. It also provides a way to ignore a list of buffer names in this cycle. Typically, users will ignore systems buffers like *Help* or *Message*.

Ignored buffers but will be suggested if typed characters matches nothing but filtered buffer names.

To customize list of ignored buffers : M-x customize-variable RET ido-ignore-buffers RET

Example:

Key	Effect
<ctrl>+x <ctrl>+<down>	Run ido interactive buffer selection
<right>	(in ido) next buffer suggestion
<left>	(in ido) previous buffer suggestion
RET	(in ido) display selected buffer
<ctrl>+x <ctrl>+<right>	display next buffer (iflipb)
<ctrl>+x <ctrl>+<left>	display previous buffer (iflipb)

Cursor Bindings

Key	Effect
<home>	move cursor to beginning of line
<select>	move cursor to end of line
<alt>+<up>	move cursor to beginning of buffer
<alt>+<down>	move cursor to end of buffer
<ctrl>+<left>	move cursor to beginning of word
<ctrl>+<right>	move cursor to end of word
<ctrl>+x <right>	move cursor to the right window
<ctrl>+x <left>	move cursor to the left window
<ctrl>+x <up>	move cursor to the top window
<ctrl>+x <down>	move cursor to the bottom window
<ctrl>+x <ctrl>+g	move cursor to given line

Other bindings

Key	Effect
<ctrl>+x <ctrl>+f	open file with xtdmacs's file opener
<alt>+<plus>	enlarge current window's height
<alt>+<minus>	shrink current window's height
<alt>+<delete>	delete previous word (no kill-ring)
<alt>+s	display speed-bar
<alt>+/	auto-complete current word
<ctrl>+d	search and replace
<ctrl>+f	search and replace regexp
<alt>+d	align regexp
<ctrl>+<F11>	toggle terminal shell
<ctrl>+l	insert current date
<alt>+q	comment region
<alt>+a	uncomment region
<F5>	delete buffer's trailing white-spaces
<ctrl>+<F5>	refresh buffer syntax colors
<F11>	display menu

File Opener

xtdmacs-find package provides an overload of standard emacs' find-file function. This overload allows to open existing files to specified line and column number.

# open file to line 38
$ emacs -nw ~/.emacs:38

# open file to line 38 and column 5
$ emacs -nw ~/.emacs:38:5

# open file normally
$ emacs -nw ~/.emacs

# open unexisting file
$ emacs -nw ~/does_not_exist:20:4
# this will literally open the file named "does_not_exist:20:4"

To enable Xtdmacs' find overload, you need to load package at start up :

;;in your .emacs:
(require 'xtdmacs-find)

Generic code

xtdmacs-code-mode enables multi-language tools that help editing code.

Column enforce

column-enforce colors text beyond a given column, discouraging (but not preventing) the developer to make too long lines.

To customize column limit :

M-x customize-variable RET fill-column RET

To customize warning face :

M-x customize-face RET column-enforce-face RET

Line number

linum-mode displays current line number and fix default window margin

To customize columns number face :

M-x customize-face RET linum RET

More generally, to customize the linum mode :

M-x customize-group RET linum RET

Aligning variables and parameters

xtdmacs-code-mode provides two utility functions that format a specific region to a matrix readable form :

• xtdmacs-code-align-vars
• xtdmacs-code-align-args

// given this code snippet :
// mark
void myfunction(const std::string& p_parameter1,
                int p_param2,
                std::vector<std::string>& p_result);
// cursor

// xtdmacs-code-align-args between mark and cursor will produce :
void myfunction(const std::string&        p_parameter1,
                int                       p_param2,
                std::vector<std::string>& p_result);


// given this code snippet :
// mark
  std::cout << "my current process" << l_tmp
            << "is about to fail because of " << l_reason
            << std::endl;
// cursor

// xtdmacs-code-align-args between mark and cursor will produce :
  std::cout << "my current process"           << l_tmp
            << "is about to fail because of " << l_reason
            << std::endl;



// given this code snippet :
void foo(void)
{
// mark
  int l_var1 = 0;
  string l_name = "bar";
  const vector<string> l_contacts = { "foo", "bar" };
// cursor
}


// xtdmacs-code-align-vars between mark and cursor will produce :
void foo(void)
{
  int                  l_var1     = 0;
  string               l_name     = "bar";
  const vector<string> l_contacts = { "foo", "bar" };
}

This feature relies on a strict parameter and variables naming convention.

• parameters : p[cs]?_.* | p[cs]?[A-Z].*
• variables : l[cs]?_.* | l[cs]?[A-Z].*
• members : m[cs]?_.* | m[cs]?[A-Z].*
• globals : g[cs]?_.* | g[cs]?[A-Z].*
• counters : c[cs]?_.* | c[cs]?[A-Z].*

Note: c and s optional modifiers stands respectively for const and static

Code Bindings

Key	Effect
<ctrl>+<alt>+<up>	move cursor to beginning of current expression
<ctrl>+<alt>+<down>	move cursor to end of current expression
<alt>+q	comment region
<alt>+a	uncomment region
<F4>	indent region
<ctrl>+<F4>	indent buffer
<alt>+d	runs align-regexp interactively
<ctrl>+<F1>	align variables between mark and cursor
<ctrl>+<F2>	align parameters between mark and cursor
<alt>+f	fold current element using yafolding-mode
<ctrl>+<F2>	fold all elements using yafolding-mode

Compile

xtdmacs-compile++-mode wraps the default compilation mode in order to provide a set of predefined compilation commands. It also allows to use function instead of plain string as default compile commands.

There is 6 predefined commands :

• :compile
• :test
• :deploy
• :doc
• :lint
• :manual

Where each commands are meant to be overridden in each specific language modes. By default, the all run make -j in the current directory.

Window management

xtdmacs-compile++ dedicates a window to the compilation buffer's preventing emacs to use it to open new files. It also sets this window's height according to xtdmacs-compile++-buffer-height variable and enables optionally automatic scrolling if xtdmacs-compile++-scroll-output is non nil.

Behind the curtain

The predefined commands are defined in the xtdmacs-compile++-config-alist variable.

Where xtdmacs-compile++-config-alist is an alist of the form

(("<mode-name>" .
    ((:<command1> . config-alist)
     (:<command2> . config-alist))))

and where each config-alist is an alist of the form

((:get-params . function)
 (:command    . string-or-function))

The <mode-name> gives a different configuration for the current major mode. When current major mode is not found, it falls back to the default key which values is given by xtdmacs-compile++-default-config-alist.

The <command> is one of the pre-defined command :compile, :test, :deploy, :doc :lint and :manual.

The :get-params function is called interactively to prompt for specific parameters of the command. Ex. for c++ :compile command, we prompt for working directory, optional environment variables and specific script to run.

The :command item build the final command send to default compilation-mode. Ex. for c++ it will construct something like cd dir && key=value make -j from values prompted by :get-params.

Usually, :get-params uses xtdmacs-compile++-config-alist itself to store values given by user. It also read defaults values from this variable when ran non interactively.

((:compile .
   ((:dir        . "~/build")
    (:env        . "VE=1")
    (:bin        . "make -j 12")
    (:get-params . xtdmacs-compile++-default-params)
    (:command    . xtdmacs-compile++-default-command))))

Compile API

This mode provides utility functions that helps building your own :get-params, :command and default functions value.

Helper functions

• xtdmacs-compile++-get-nearest-filename (name) returns the closest path parent to current buffer file that contains a file or a directory named name

• xtdmacs-compile++-get-dir-locals-directory returns the path containing the nearest .dir-locals.el configuration file (nil if none)

• xtdmacs-compile++-get-dir-git return the closest parent from buffer containing a .git directory, often used as project root directory.

• xtdmacs-compile++-get-dir-buffer returns the directory path of current buffer.

• xtdmacs-compile++-guess-directory returns the build directory assuming your are using automake's VPATH builds in a directory named .release in your project root

• xtdmacs-compile++-get-current-branch returns (if any) the git branch name of the current buffer

Params functions

Line mode

xtdmacs-code-line-mode tweaks the mode-line format in order to display :

• buffer name: with the customizable face mode-line-buffer-id
• line and column of current point position
• percentage of the current buffer scroll
• function name, if any, or the current buffer directory

The function name is deduces by which-func-mode which is customizable with the following command:

C-u M-x customize-mode RET which-func-mode RET

Example:

Spelling

xtdmacs-code-spell-mode and xtdmacs-code-spell-prog-mode are wrapping of flyspell-mode and flyspell-prog-mode. They both detected spelling error in current buffer. The first analyzes all available text and the second only analyzes strings and comment.

Spell Configuration

The modes are affected by the following customizable variables :

• M-x customize-variable RET xtdmacs-code-spell-ignore-regexp RET : list of regexp patterns to ignore while spelling the buffer.

• M-x customize-variable RET xtdmacs-code-spell-max-lines RET : maximum allowed buffer lines to automatically run flyspell on buffer.

• M-x customize-variable RET ispell-local-dictionary RET : default spelling dictionary

Spell Faces

The following faces are used by underlying flyspell mode :

• M-x customize-face RET flyspell-incorrect RET : Face to display detected spelling errors

• M-x customize-face RET flyspell-duplicate RET : Face to display detected duplicated words.

Spell API

Useful functions :

• M-X flyspell-buffer RET : refresh spelling analysis of current buffer

• M-X xtdmacs-code-spell-change-dictionary RET : changes spelling dictionary and set new dictionary are local file variable.

• M-X xtdmacs-code-spell-next-word RET : interactively correct the next detected error

• M-X xtdmacs-code-spell-prev-word RET : interactively correct the previous detected error

<ctrl>+c <ctrl>+<left>	xtdmacs-code-spell-prev-word

Language specific modes

C++

xtdmacs-code-cpp-mode provides the following features :

• Fix -std=c++11 enum class : Aging c++-mode doesn't handle new enum class syntax available in c++11 and leads to a broken indentation. This minor mode fixes c-offsets-alist and properly indents this structure.

• Cycling through headers and implementation files : When editing a c++ header (.hh), we often need to visit the corresponding implementation (.cc) and vice versa. The mode defines a function that searches for file that matches current buffer file name with the correct extension. Another function does the same but creates the file if it doesn't already exist. Because c++ extensions are not well standardized, you can set the list of searched extension in the variable xtdmacs-code-cpp-header-extensions .

• Automatic indentation : The mode offers to automatically indent the whole buffer at open and/or at close. (*)

  (*) Personnal note : Emacs is the best market product for editing and indenting code. Sadly, not everybody uses Emacs and real world code is often poorly indented. This usage is certainly highly arguable but I've been using this in industrial collaborative environment for the past ten years and automatic code indentation solved far more problems than it has created.

• Keywords : The mode provides many font-lock additional keywords. Some of them try to catch the new C++11/14 language keywords like nullptr or decltype or utf-8 strings . Others define font-lock rules to color particular naming patterns, allowing to easily distinguish local variables, parameter, class members, const and static attributes without need to use heavy syntax analyzers that often need to actually compile the code.

• Renaming variables : The mode defines a function that generated the correct query-replace-regexp call to rename symbol at point to match one of the prefix rule defined for local variable, parameters or class member syntax coloring.

• Completion : The mode integrates irony and auto-complete to provide C++ code completion. xtdmacs-code-cpp-complete-irony-async is bound to M-. by default.

  Completion is asynchronous, buffer name will be colored with xtdmacs-code-cpp-ac-irony-working-face until completion is ready. First call may be quite long, further calls are cached by server and will return immediately.

  It relies on a completion server provided by irony which can be automatically installed using M-x irony-install-server RET.

  In addition, irony-get-type bound to C-e keys prints the type of symbol under cursor in the minibuffer.

C++ Configuration

• M-x customize-variable RET xtdmacs-code-cpp-indent-load-auto RET : tells if buffer should be automatically indented at load.

• M-x customize-variable RET xtdmacs-code-cpp-indent-save-auto RET : tells if buffer should be automatically indented at save.

• M-x customize-variable RET xtdmacs-code-cpp-header-extensions RET : defines the list of extensions that are searched when cycling through headers and implementation files. Note: this list can have more than two elements, this is useful to handle template implementations or inline definition files like .hpp or .hxx .

• M-x customize-variable RET xtdmacs-code-cpp-keywords-alist RET : alist of keywords and faces to add to font-lock when mode is activated.

C++ Faces

The mode uses faces defined in xtdmacs-code-mode. See M-x customize-group RET code RET .

C++ API

• M-x xtdmacs-code-cpp-header-cycle RET : cycle through extensions defined by xtdmacs-code-cpp-header-extensions .

• M-x xtdmacs-code-cpp-header-cycle-create RET : cycle through extensions defined by xtdmacs-code-cpp-header-extensions, create files if they don't exist.

• M-x xtdmacs-code-cpp-rename-variable RET : rename variable under cursor. The function prompt interactively for renaming prefix.

• M-x irony-get-type RET : display in minibuffer the type of the symbol under cursor.

• M-x xtdmacs-code-cpp-complete-irony-async RET : trigger completion at current point.

C++ Compilation

Commands are set by xtdmacs-code-cpp-compile-alist which can be customized by running:

• M-x customize-variable RET xtdmacs-code-cpp-compile-alist RET

By default xtdmacs-code-cpp-compile-alist takes the value of xtdmacs-compile++-default-config-alist.

Go

xtdmacs-code-go-mode provides the following features:

• Keywords: define font-lock rules to color particular naming patterns, allowing to easily distinguish local variables, parameter... etc.

• Completion: Integrates gocode which must be manually installed

• Formatting: Provides automatic formatting functions, on-demand or at load/save

• Snippets: Loads default go language snippets

• Compilation: Provides default commands for compilation and linter checking

Go Compilation

• compile: Runs go build from top git directory. Output binary name is computed from current package name.

• lint: runs gometalinter on current package. gometalinter must be installed manually.

Python

xtdmacs-code-python-mode provides the following features :

• Automatic indentation on load and/or save

• Overrides default xtdmacs-compile++ configuration :

  • run pylint on current buffer
  • run unittest script

• Defines font-lock keywords to identify local variables, parameters and class members

• Defines useful functions used in compilation commands

Python Faces

The mode uses faces defined in xtdmacs-code-mode.

Python API

• xtdmacs-code-python-module-root : Returns buffers' most distant parent directory containing a ___init__.py file. If no such file found, returns buffer's file directory.

• xtdmacs-code-python-project-root : Returns parent directory of module root. If module root couldn't be identified, returns buffer's file directory.

• xtdmacs-code-python-pylint-getargs : Constructs argument string to pass to compile command. If .pylintrc is found in project root, includes --rcfile=file in constructed string.

• xtdmacs-code-python-pylint-bin Constructs compile command from xtdmacs-code-python-pylint-bin-path and xtdmacs-code-python-pylint-args. The buffer's file path is added as last argument on the returned command.

• xtdmacs-code-python-test-bin Constructs compile command from xtdmacs-code-python-test-bin-path and xtdmacs-code-python-test-args.

• xtdmacs-code-python-params : same as xtdmacs-compile++-default-params, prompt only for directory and binary command.

• xtdmacs-code-python-command : same as xtdmacs-compile++-default-command, construct final compile command from parameters built by xtdmacs-code-python-params .

Python Configuration

• M-x customize-variable RET xtdmacs-code-python-pylint-bin-path RET

  • pylint static code checker file path

• M-x customize-variable RET xtdmacs-code-python-pylint-args RET

  • Static string or function to use as pylint script argument

• M-x customize-variable RET xtdmacs-code-python-test-bin-path RET

  • Unit test runner file path. If nil, use default xtdmacs runner

• M-x customize-variable RET xtdmacs-code-python-test-args RET

  • Static string or function to use as test binary arguments

• M-x customize-variable RET xtdmacs-code-python-indent-save-auto RET

  • Enables python code auto-indentation on save.

• M-x customize-variable RET xtdmacs-code-python-indent-load-auto RET

  • Enables python code auto-indentation on load.

• M-x customize-variable RET xtdmacs-code-python-keywords-alist RET

  • List of additional python font-lock keywords

• M-x customize-variable RET xtdmacs-code-python-compile-alist RET

  • overrides xtdmacs-compile++-config-alist for python-mode

Python Compilation

Commands are set by xtdmacs-code-python-compile-alist which can be customized by running:

• M-x customize-variable RET xtdmacs-code-python-compile-alist RET

• compile: run pylint on project root. Root is deduced by walking buffer's parent directory until no __init__.py file is found.

  Pylint configuration is searched by order of priority in the following locations:

  • <root>/.pylintrc
  • ${HOME}/.pylintrc
  • <xtdmacs_installdir>/vendor/pylintrc

• test: run unittests. Binary is given by xtdmacs-code-python-test-bin-path and defaults to <xtdmacs_installdir>/bin/unittests.py which is a default python unittest wrapper that produces a parsable output.
