Awk Support implements an Awk-IDE for Awk/gAwk. It is written to considerably
speed up writing Awk script code in a consistent style. This is done by
inserting complete statements, comments, idioms, and code snippets. There are
many additional hints and options which can improve speed and comfort when
writing Awk scripts.

1. USAGE WITH GUI (gVim) awksupport-usage-gvim
If the menus are not visible call them using the item "Load Awk Support" from the standard Tools-menu.
1.1 MENU 'Comments' awksupport-comments
1.1.1 APPEND ALIGNED COMMENTS TO CONSECUTIVE LINES awksupport-comm-aligned
In NORMAL MODE the menu item 'end-of-line comment' will append a comment to the current line. In VISUAL MODE, this item will append aligned comments to all marked lines. Marking the 4 linesx = 33y = 44z = 55and choosing 'end-of-line comment' will yieldx = 33 # |y = 44 #z = 55 #The cursor position above is marked by '|'. Empty lines will be ignored. The default starting column is 49 ( = (multiple of 2,4, or 8) + 1 ). This can be changed by setting a global variable in the file '.vimrc', e.g. :let g:Awk_LineEndCommColDefault = 45The starting column can also be set by the menu item 'Comments->adjust end-of-line com.' . Just position the cursor in an arbitrary column (normal mode; column number is shown in the Vim status line) and choose this menu item. This setting is buffer related. If the cursor was at the end of a line you will be asked for a column number because this position is most likely not the desired starting column. Your choice will be confirmed. 1.1.2 ADJUST END-OF-LINE COMMENTS awksupport-comm-realign
After some copy/paste/change actions comments may be misaligned:x = 33 # this is xy = 44 # and yz = 55 # and now zRealignment can be achieved with the menu item 'adjust end-of-line com.' In normal mode the comment (if any) in the current line will be aligned to the end-of-line comment column (see above) if possible. In visual mode the comments in the marked block will be aligned:x = 33 # this is xy = 44 # and yz = 55 # and now zAnother way is to use the hotkey \cj. In normal and insert mode the current line will be adjusted. To adjust n lines starting with the current one use n\cj. 1.1.3 COMMENT/UNCOMMENT awksupport-comm-uncomm
The comment sign # can be set or removed at the beginning of the current line or for a marked block using the menu items 'comment' (or \cc) and 'uncomment' (or \cu). A single line needs not to be marked (normal mode, insert mode). A marked blockx = 33 # this is xy = 44 # and yz = 55 # and now zwill be changed into (and vice versa)# x = 33 # this is x# y = 44 # and y# z = 55 # and now z1.1.4 FRAME COMMENTS, FILE HEADER, ... awksupport-comm-templates
Frame comments, function descriptions and file header comments are read as templates from the appropriate files (see |awksupport-templates|). 1.1.5 KEYWORD COMMENT awksupport-comm-keywords
Preliminary end-of-line comments to document (and find again!) places where
work will be resumed shortly, like
# :BUG:19.12.2012 17:06:fgm: ... your comment
Here 'fgm' is the authors reference (see section 4. for templates and tags).
Usually these comments are not meant for the final documentation.
1.2 MENU 'Statements' awksupport-statements
1.2.1 NORMAL MODE, INSERT MODE. awksupport-stat-norm-ins
An empty statement will be inserted and properly indented. The item 'if block' will insert an if-statement:if ( ) {<-IF_PART->}The statement will be indented. 1.2.2 VISUAL MODE awksupport-stat-visual
The highlighted areaxxxxxxxxxxcan be surrounded by one of the following statements ( '|' marks the cursor position after insertion):+--------------------------------------------------+|do {||xxxxx||xxxxx||} while (| ) # ----- end do-while ----- |+--------------------------------------------------+|for ( in <-ARRAY-> ) {||xxxxx||xxxxx||}|+--------------------------------------------------+|if (| ) { ||xxxxx||xxxxx||}|+--------------------------------------------------+|if (| ) { ||xxxxx||xxxxx||}||else {||||}|+--------------------------------------------------+|while (| ) { ||xxxxx||xxxxx||}|+--------------------------------------------------+|switch (| ) { ||case <-LABEL->:||xxxxx||xxxxx||break||||case <-LABEL->:||break||||case <-LABEL->:||break||||default:||break||} # ----- end switch -----|+--------------------------------------------------+|BEGIN {||xxxxx||xxxxx||} # ----- end BEGIN -----|+--------------------------------------------------+|END {||xxxxx||xxxxx||} # ----- end END -----|+--------------------------------------------------+The whole statement will be indented after insertion.
1.3 MENU 'Idioms' awksupport-idioms
Your often used programming idioms other than the basic language statements.
1.4 MENU 'Functions' awksupport-functions
The gAwk functions organized in several groups. The numeric functions can be
accessed via menu or via the hotkey \fn (+ tab expansion). Please see section
USAGE WITHOUT GUI |(awksupport-usage-vim|) for the other hotkeys.
1.5 MENU 'Special Variables' awksupport-specvars
The gAwk special variables organized in the two groups - auto-set - user modifiable
1.6 MENU 'Regex' awksupport-regex
This menu can be used to compose regular expressions with a few keystrokes. In normal mode the items insert the shown constructs after the cursor. Some of them can enclose a marked text. The marked textxxxxxwill be changed into(xxxxx)by the menu item 'grouping'.
1.7 MENU 'SNIPPETS' awksupport-snippets
1.7.1 Code Snippets awksupport-codesnippets
Code snippets are pieces of code which are kept in separate files in a special directory. File names are used to identify the snippets. The default snippet directory is '$HOME/.vim/awk-support/codesnippets'. Snippets are managed with the 4 itemsAwk -> Snippets -> read code snippetAwk -> Snippets -> view code snippetAwk -> Snippets -> write code snippetAwk -> Snippets -> edit code snippetfrom the Statements submenu. Creating a new snippet:
When nothing is marked, 'write code snippet' will write the whole buffer to a snippet file, otherwise the marked area will be written to a file. Insert a snippet:
Select the appropriate file from the snippet directory ('read code snippet').
The inserted lines will be indented.
Indentation / no indentation
Code snippets are normally indented after insertion. To suppress indentation
add the file extension "ni" or "noindent" to the snippet file name, e.g.
parameter_handling.noindent
Snippet browser
Under a GUI a file requester will be put up. Without GUI the filename will be
read from the command line. You can change this behavior by setting a global
variable in your $HOME/.vimrc :
let g:Awk_GuiSnippetBrowser = 'commandline'
The default value is 'gui'.
1.7.2 Edit Templates awksupport-templates-edit
Nearly all menu items insert code snippets or comments. All of these are contained within template files and can be changed by the user to meet their requirements (see|awksupport-templates|on how to use the template system). The menu item 'edit templates' opens the main template file in a local plugin installation. This is usually the file '$HOME/.vim/awk-support/templates/Templates'. There may be dependent files loaded from the main file. Now change whatever file you want, save it, and click on the menu item 'reread templates' to read in the file(s) and to rebuild the internal representation of the templates. If menu items, hotkeys, or shortcuts have been added or changed these changes will be applied with the next start of Vim.
1.8 MENU 'Run' awksupport-run
1.8.1 Run Script awksupport-run-script
Run the script in the current buffer. The output destination can be chosen using the menu item 'Run->output: ...'. There are 3 choices: VIM command line, separate output buffer and xterm (see |awksupport-output|). 1.8.2 Syntax Check awksupport-syntax-check
The script is run asawk -e 'BEGINto check the syntax. Errors and warnings will be shown in a quickfix buffer. For convenience consider to use maps like{ exit(0) }END{ exit(0) }' -f scriptnamenoremap<silent><F5>:copen<CR>noremap<silent><F6>:cclose<CR>noremap<silent><F7>:cp<CR>noremapin your .vimrc file to jump to the error locations (F7,F8) and to open and close the error window (F5,F6). This makes navigation a lot easier (see also file 'customization.vimrc', |awksupport-custom-files|). The error list and the error locations in your source buffer will be synchronized. 1.8.3 Lint Check awksupport-lint-check<silent><F8>:cn<CR>
The script is run as
awk --lint -f scriptname arguments
Errors and warnings will be shown in a quickfix buffer. The error list and
the error locations in your source buffer will be synchronized.
1.8.4 Command Line Arguments awksupport-cmdline-args
The item 'script cmd. line arg.' calls an input dialog which asks for command line arguments. These arguments are forwarded to the script which is run by the 'run' item. The arguments are kept until you change them. The arguments can contain pipes and redirections, e.g.infile.txt | sort -rn > result.txtFor file names tab-expansion will work. The ex command:AwkScriptArguments ...can also be used to set the command line arguments for the current script. The arguments belong to the current buffer (that is, each buffer can have its own arguments). The input dialog has a history. If the buffer gets a new name with "save as" the arguments will now belong to the buffer with the new name. 1.8.5 Awk Command Line Arguments awksupport-awk-args
The item 'AWK cmd. line arg.' calls an input dialog which asks for command line arguments for the awk interpreter. These arguments are forwarded to the call of the script which is run by the 'run' item. The arguments are kept until you change them. The arguments belong to the current buffer (that is, each buffer can have its own independent arguments). The input dialog has a history. The ex command:AwkArguments ...can also be used to set the command line arguments for Awk. If the buffer gets a new name with "save as" the arguments will now belong to the buffer with the new name. 1.8.6 Hardcopy awksupport-hardcopy Generates a PostScript file from the whole buffer or from a marked region. The hardcopy goes to the current working directory. If the buffer contains documentation or other material from non-writable directories the hardcopy goes to the HOME directory. The output destination will be shown in a message. The print header contains date and time according the current locale. The definition used islet s:Awk_Printheader = "%<%f%h%m%< %=%The current locale can be overwritten by changing the language, e.g.{strftime('%x %X')}Page %N":language Cor by setting a global variable in the file '.vimrc', e.g. :let g:Awk_Printheader = "%<%f%h%m%< %=%See :h printheader and :h strftime() for more details. 1.8.7 Settings awksupport-settings{strftime('%x %X')}SEITE %N"
Displays some Awk Support plugin settings. 1.8.8 Xterm Size awksupport-xterm
The size of the xterm used for running the script (below) can be set by this menu item. The default is 80 columns with 24 lines. This feature is not available under MS-Windows. 1.8.9 Change Output Destination awksupport-output
Running a Awk script can be done in three ways:
(1) The script can be run from the command line as usual.
(2) The output can be directed into a buffer with name "Awk-Output".
The buffer and its content will disappear when the window is closed or
reused otherwise. If this window remains open it will be used for the next
run. If the script doesn't produce shell output the output window will
not be opened (but you will see a message).
There is no file behind the window Awk-Output but the content can be
saved with a 'save as'.
(3) The script can be run in an xterm.
The output method can be chosen with the menu item 'Run->output: ...'.
This menu has three states:
output: VIM->buffer->xterm
output: BUFFER->xterm->vim
output: XTERM->vim->buffer
The first (uppercase) item shows the current method. The default is 'vim'.
This can be changed by setting the variable g:Awk_OutputGvim to another
value. Possible values are 'vim', 'buffer' and 'xterm'.
Vim (non-GUI) : The output destination can be toggled between (1) and (2)
using the hotkey \ro .
The xterm defaults can be set in .vimrc by the variable g:Awk_XtermDefaults .
The default is "-fa courier -fs 12 -geometry 80x24" :
font name : -fa courier
font size : -fs 12
terminal size : -geometry 80x24
See 'xterm -help' for more options. Xterms are not available under MS-Windows.
1.9 Main Menu Item 'AWK manual' awksupport-help
Display the Awk manual in a separate buffer.
2. USAGE WITHOUT GUI (Vim) awksupport-usage-vim
The frequently used constructs can be inserted via key mappings. The mappings
are also described in the document 'awk-hotkeys.pdf' (reference card, part of
this package).
All mappings are filetype specific: they are only defined for buffers with
filetype 'awk' to minimize conflicts with mappings from other plugins.
Hint: Typing speed matters. The combination of a leader ('\') and the
following character(s) will only be recognized for a short time.
Some mappings can be used with range (of lines). In normal mode
\cl
appends a end-of-line comment to the current line, whereas
4\cl
appends end-of-line comments to the 4 lines starting with the current line.

Changing the default map leader '\'
The map leader can be changed by the user by setting a global variable in the
file .vimrc
let g:Awk_MapLeader = ','
The map leader is now a comma. The 'end-of-line comment' command is now
defined as ',cl'. This setting will be used as a so called local leader and
influences only files with filetype 'vim'.

3.2 GLOBAL VARIABLES awksupport-custom-variables
Several global variables are checked by the plugin to customize it:
Global Variable Default Value
g:Awk_Awk 'awk' (Linux/U**X), 'awk.exe' (Windows)
g:Awk_LocalTemplateFile $HOME.'/.vim/awk-support/templates/Templates'
g:Awk_GlobalTemplateFile $VIM.'/vimfiles/awk-support/templates/Templates'
g:Awk_CodeSnippets $HOME.'/.vim/awk-support/codesnippets' (Linux/U**X)
$VIM.'\vimfiles\awk-support/codesnippets/'(Windows)
g:Awk_LoadMenus 'yes'
g:Awk_CreateMenusDelayed 'no'
g:Awk_RootMenu '&Awk'
g:Awk_GuiSnippetBrowser 'gui'
g:Awk_InsertFileHeader 'yes'
g:Awk_LineEndCommColDefault 49
g:Awk_Printheader '%<%f%h%m%< %=%{strftime('%x %X')} Page %N'
'vim.exe' (Windows)
g:Awk_MapLeader '\'
Global Variable Description
g:Awk_Awk set the awk executable
g:Awk_LocalTemplateFile sets the local template file (see|awksupport-templates|)
g:Awk_GlobalTemplateFile sets the global template file (see|awksupport-templates|)
g:Awk_CodeSnippets set the personal code snippet directory
g:Awk_LoadMenus Load menus and mappings ("yes", "no") at start up.
g:Awk_CreateMenusDelayed Load menus only with filetype 'awk'
g:Awk_RootMenu The name of the root menu item of this plugin
(see |awksupport-custom-root|).
g:Awk_GuiSnippetBrowser code snippet browser: 'gui', 'commandline'
g:Awk_InsertFileHeader insert file description comment in a new file ('yes', 'no')
g:Awk_LineEndCommColDefault default starting column for line end comments
g:Awk_Printheader hardcopy header format
g:Awk_MapLeader the map leader for hotkeys (see|awksupport-usage-vim|)
To override the defaults add appropriate assignments in '.vimrc', e.g.
let g:Awk_MapLeader = ','
3.3 THE ROOT MENU awksupport-custom-root
The variable g:Awk_RootMenu, if set (in '.vimrc' or in '.gvimrc'), sets the name of the single gVim root menu item in which the Awk submenus will be appear. The default is'&Awk'If you want to set the plugin root menu into another menu, e.g. 'Plugin', this is done by the following line in '.vimrc'let g:Awk_RootMenu = "&Plugin"
3.4 System-wide installation awksupport-system-wide
A system-wide installation (one installation for all users) is done as follows. As ****** SUPERUSER ****** : (1) Find the Vim installation directory. The Vim ex command ':echo $VIM' gives '/usr/local/share/vim' or something like that. Beyond this directory you will find the Vim installation, e.g. in '/usr/local/share/vim/vim73' if Vim version 7.3 has been installed. (2) Create a new subdirectory 'vimfiles', e.g. '/usr/local/share/vim/vimfiles'. (3) Install Awk Support Copy the archive 'awk-support.zip' to this new directory and unpack it:unzip awk-support.zip(4) Generate the help tags::helptags $VIM/vimfiles/docSPECIAL CASES. Some Linux distributions use non-standard names for Vim directories. SUSE has a directory '/usr/share/vim/site' to put plugins in. These directories will not be found automatically. After installing the plugin below '/usr/share/vim/site' the use of the templates will be enabled by the following line in '$HOME/.vimrc':let g:Awk_GlobalTemplateFile = '/usr/share/vim/site/awk-support/templates/Templates'As ****** USER ****** : The plugin tries to create a minimal template file 'Templates' (and the necessary directory '$HOME/.vim/awk-support/templates') when the first buffer with filetype 'vim' will be opened. You should edit this file to personalize some macros. You can also have local templates which override the global ones. To see a messages in this case set a global variable in '$HOME/.vimrc' (Windows: '$HOME\_vimrc'):let g:Awk_TemplateOverriddenMsg= 'yes'The default is 'no'. Create your private snippet directory:mkdir --parents $HOME/.vim/awk-support/codesnippetsYou may want to copy the snippets coming with this plugin (in $VIM/vimfiles/awk-support/codesnippets) into the new directory or to set a link to the global directory.
4. TEMPLATE FILES AND TAGS awksupport-templates
4.1 Template Files awksupport-templates-files
Nearly all menu items insert code snippets or comments. All of these are contained within template files and can be changed by the user to meet their requirements. The menu shortcuts (e.g. 'c' for the Comments menu) and the menu item hotkeys (e.g. '\ct' insert date and time) are also defined in the templates. The template engine comes as a separate plugin contributed by Wolfgang Mehner. This section is a short introduction to this template system. Please see |templatesupport| for more information. The master template file is '$HOME/.vim/awk-support/templates/Templates' for a user installation and '$VIM/vimfiles/awk-support/templates/Templates' for a system-wide installation (see |awksupport-system-wide|). The master template file starts with a macro section followed by templates for single menu items or better by including other template files grouping the templates according to the menu structure of this plugin. The master file usually looks like this (my settings as an example):§ =============================================================§ User Macros§ =============================================================SetMacro( 'AUTHOR', 'Dr. Fritz Mehner' )SetMacro( 'AUTHORREF', 'fgm' )SetMacro( 'COMPANY', '' )SetMacro( 'COPYRIGHT', 'Copyright (c) |YEAR|, |AUTHOR|' )SetMacro( 'EMAIL', 'mehner.fritz@web.de' )SetMacro( 'LICENSE', 'GNU General Public License' )SetMacro( 'ORGANIZATION','FH Südwestfalen, Iserlohn' )SetFormat( 'DATE', '%x' )SetFormat( 'TIME', '%H:%M' )SetFormat( 'YEAR', '%Y' )SetStyle( 'default' )§ =============================================================§ File Includes and Shortcuts§ =============================================================MenuShortcut( 'Comments', 'c' )MenuShortcut( 'Statements', 's' )MenuShortcut( 'Idioms', 'i' )MenuShortcut( 'Functions', 'f' )MenuShortcut( 'Special Variables', 'v' )MenuShortcut( 'Regex', 'x' )IncludeFile( 'comments.templates' )IncludeFile( 'statements.templates' )IncludeFile( 'idioms.templates' )IncludeFile( 'functions.templates' )IncludeFile( 'specvar.templates' )IncludeFile( 'regex.templates' )Lines starting with a paragraph sign are comments. The section starting withSetMacro( 'AUTHOR', 'Dr. Fritz Mehner' )assigns values to predefined tags (macros). Arbitrary user-defined macros are possible. The macro name must follows the rules for a C language identifier: first character letter or underscore; case matters; digits are allowed beginning with the second character. The statementIncludeFile( 'comments.templates' )includes the templates from the file 'comments.templates' (in the same directory). An absolute path would also be possible. The statementMenuShortcut( 'Comments', 'c' )sets 'c' as the shortcut for the Comments menu.
4.2 Macros awksupport-templates-macros
The following macro names are predefined. The first group is used to
personalize templates.
----------------------------------------------------------------------------
PREDEFINED MACROS DEFAULT VALUE
----------------------------------------------------------------------------
|BASENAME| filename without path and suffix
|DATE| the preferred date representation for the current locale
without the time
|FILENAME| filename without path
|PATH| path without filename
|SUFFIX| filename suffix
|TIME| the preferred time representation for the current locale
without the date and the time zone or name or abbreviation
|YEAR| the year as a decimal number including the century
----------------------------------------------------------------------------
PREDEFINED TAGS USED IN TEMPLATES
----------------------------------------------------------------------------
<CURSOR> The cursor position after insertion of a template.
<+text+>,<-text-> See |awksupport-templates-jumptags|.
{+text+},{-text-}
<SPLIT> The split point when inserting in visual mode
(see|awksupport-templates|)
A dependent template file can start with its own command section. There is no
need to have all user defined macros in the master file.
4.2.1 User defined formats for date and time awksupport-templates-date
The format for |DATE| ,|TIME| , and|YEAR| can be set by the user. The
defaults are
|DATE| '%x'
|TIME| '%X'
|YEAR| '%Y'
See the manual page of the C function strftime() for the format. The accepted
format depends on your system, thus this is not portable! The maximum length
of the result is 80 characters.

4.3 Templates awksupport-templates-names
4.3.1 Template Definition awksupport-templates-definition The template behind a menu item is identified by a given name. The first part of the name identifies the menu name, the second part identifies the item. A template definition starts with a template header with the following syntax: == menu_name.template_name == options == The options are described here: |template-support-options|. 4.3.2 The jump tags<+text+>etc. awksupport-templates-jumptags There are four jump tag types which can be used as jump targets in templates:<+text+>Can be jumped to by hitting Ctrl-j.{+text+}Same as<+text+>. Used in cases where indentation gives unwanted results with the first one.<-text->Same as the two above. Will be removed if the template is used{-text-}in visual mode. The text inside the brackets is userdefined and can be empty. The text can be composed from letters (uppercase and lowercase), digits, and underscores. After the insertion of an template these jump targets will be highlighted. 4.3.3 Command Ctrl-j awksupport-Ctrl-j Use the command Ctrl-j to jump to the next target. The target will be removed and the mode will switched to insertion. Ctrl-j works in normal and in insert mode. The template for an if-else-statement can be written as follows:== Statements.if block else == map:sife, shortcut:l ==if (<CURSOR>) {<SPLIT><-IF_PART->}else {<-ELSE_PART->}The cursor will be set as shown. When the condition is specified a Ctrl-j let you jump to the target<-IF PART->and deletes it. When the block is written a Ctrl-j leads you to the else-part. The target<-ELSE_PART->disappears and you can type on.

6. TROUBLESHOOTING awksupport-troubleshooting
* I do not see any new main menu item.
- Was the archive extracted into the right directory?
* How can I see what was loaded?
- Use ':scriptnames' from the Vim command line.
* No main menu item.
- Loading of plugin files must be enabled. If not use
:filetype plugin on
This is the minimal content of the file '$HOME/.vimrc'. Create one if
there is none, or better use customization.vimrc.
* Some hotkeys do not work.
- The hotkeys might be in use by your graphical desktop environment. The key
settings can usually be redefined.
