pico(1) General Commands Manual pico(1) Name pico - simple text editor in the style of the Alpine Composer Syntax pico [ options ] [ file ] Description Pico is a simple, display-oriented text editor based on the Alpine mes- sage system composer. As with Alpine, commands are displayed at the bottom of the screen, and context-sensitive help is provided. As char- acters are typed they are immediately inserted into the text. Editing commands are entered using control-key combinations. As a work-around for communications programs that swallow certain control characters, you can emulate a control key by pressing ESCAPE twice, followed by the desired control character, e.g. "ESC ESC c" would be equivalent to entering a ctrl-c. The editor has five basic features: paragraph justification, searching, block cut/paste, a spelling checker, and a file browser. Paragraph justification (or filling) takes place in the paragraph that contains the cursor, or, if the cursor is between lines, in the para- graph immediately below. Paragraphs are delimited by blank lines, or by lines beginning with a space or tab. Unjustification can be done immediately after justification using the control-U key combination. String searches are not sensitive to case. A search begins at the cur- rent cursor position and wraps around the end of the text. The most recent search string is offered as the default in subsequent searches. Blocks of text can be moved, copied or deleted with creative use of the command for mark (ctrl-^), delete (ctrl-k) and undelete (ctrl-u). The delete command will remove text between the "mark" and the current cur- sor position, and place it in the "cut" buffer. The undelete command effects a "paste" at the current cursor position. The spell checker examines all words in the text. It then offers, in turn, each misspelled word for correction while highlighting it in the text. Spell checking can be cancelled at any time. Alternatively, pico will substitute for the default spell checking routine a routine defined by the SPELL environment variable. The replacement routine should read standard input and write standard output. The file browser is offered as an option in the "Read File" and "Write Out" command prompts. It is intended to help in searching for specific files and navigating directory hierarchies. Filenames with sizes and names of directories in the current working directory are presented for selection. The current working directory is displayed on the top line of the display while the list of available commands takes up the bottom two. Several basic file manipulation functions are supported: file renaming, copying, and deletion. More specific help is available in pico's online help. Options +n Causes pico to be started with the cursor located n lines into the file. (Note: no space between "+" sign and number) -a Display all files including those beginning with a period (.). -b Enable the option to Replace text matches found using the "Where is" command. This now does nothing. Instead, the option is al- ways turned on (as if the -b flag had been specified). -d Rebind the "delete" key so the character the cursor is on is rubbed out rather than the character to its left. -e Enable file name completion. -f Use function keys for commands. This option supported only in conjunction with UW Enhanced NCSA telnet. -h List valid command line options. -j Enable "Goto" command in the file browser. This enables the command to permit explicitly telling pilot which directory to visit. -g Enable "Show Cursor" mode in file browser. Cause cursor to be positioned before the current selection rather than placed at the lower left of the display. -k Causes "Cut Text" command to remove characters from the cursor position to the end of the line rather than remove the entire line. -m Enable mouse functionality. This only works when pico is run from within an X Window System "xterm" window. -nn The -nn option enables new mail notification. The n argument is optional, and specifies how often, in seconds, your mailbox is checked for new mail. For example, -n60 causes pico to check for new mail once every minute. The default interval is 180 seconds, while the minimum allowed is 30. (Note: no space be- tween "n" and the number) -o dir Sets operating directory. Only files within this directory are accessible. Likewise, the file browser is limited to the speci- fied directory subtree. -rn Sets column used to limit the "Justify" command's right margin -s speller Specify an alternate program spell to use when spell checking. -t Enable "tool" mode. Intended for when pico is used as the edi- tor within other tools (e.g., Elm, Pnews). Pico will not prompt for save on exit, and will not rename the buffer during the "Write Out" command. -v View the file only, disallowing any editing. -version Print Pico version and exit. -w Disable word wrap (thus allow editing of long lines). -x Disable keymenu at the bottom of the screen. -z Enable ^Z suspension of pico. -p Preserve the "start" and "stop" characters, typically Ctrl-Q and Ctrl-S, which are sometimes used in communications paths to con- trol data flow between devices that operate at different speeds. -Q quotestr Set the quote string. Especially useful when composing email, setting this allows the quote string to be checked for when Jus- tifying paragraphs. A common quote string is "> ". -W word_separators If characters listed here appear in the middle of a word sur- rounded by alphanumeric characters that word is split into two words. This is used by the Forward and Backward word commands and by the spell checker. -q Termcap or terminfo definition for input escape sequences are used in preference to sequences defined by default. This option is only available if pico was compiled with the TERMCAP_WINS de- fine turned on. -setlocale_ctype Do setlocale(LC_CTYPE) if available. Default is to not do this setlocale. -no_setlocale_collate Do not do setlocale(LC_COLLATE). Default is to do this setlo- cale. Lastly, when a running pico is disconnected (i.e., receives a SIGHUP), pico will save the current work if needed before exiting. Work is saved under the current filename with ".save" appended. If the current work is unnamed, it is saved under the filename "pico.save". Color Support If your terminal supports colors, Pico can be configured to color text. Users can configure the color of the text, the text in the key menu, the titlebar, messages and prompt in the status line. As an added fea- ture Pico can also be used to configure the color of up to three dif- ferent levels of quoted text, and the signature of an email message. This is useful when Pico is used as a tool (with the -t command line switch.) Pico can tell you the number of colors that your terminal supports, when started with the switch -color_codes. In addition Pico will print a table showing the numerical code of every color supported in that terminal. In order to configure colors, one must use these numerical codes. For example, 0 is for black, so in order to configure a black color, one must use its code, the number 0. In order to activate colors, one must use the option -ncolors with a numerical value indicating the number of colors that your terminal sup- ports, for example, -ncolors 256 indicates that the user wishes to use a table of 256 colors. All options that control color, are four letter options. Their last two letters are either "fc" or "bc", indicating foreground color and bac- ground color, respectively. The first two letters indicate the type of text that is being configured, for example "nt" stands for normal text, so that -ntfc represents the color of the normal text, while -ntbc rep- resents the color of the background of normal text. Here is a complete list of the color options supported by Pico. -color_code displays the number of colors supported by the terminal, and a table showing the association of colors and numerical codes -ncolors number activates color support in Pico, and tells Pico how many colors to use. Depending on your terminal number could be 8, 16, or 256. -ntfc num specifies the number num of the color to be used to color normal text. -ntbc num specifies the number num of the color of the background for nor- mal text. -rtfc num specifies the number num of the color of reverse text. Default: same as background color of normal text (if specified.) -rtbc num specifies the number num of the color of the background of re- verse text. Default: same as color of normal text (if speci- fied.) -tbfc num specifies the number num of then color of text of the title bar. Default: same as foreground color of reverse text. -tbbc num specifies the number num of the color in the background of the title bar. -klfc num specifies the number num of the color of the text of the key la- bel. -klbc num specifies the number num of the color in the background of the key label. -knfc num specifies the number num of the color of the text of the key name. -knbc num specifies the number num of the color of the background of the key name. -stfc num specifies the number num of the color of the text of the status line. -stbc num specifies the number num of the color of the background of the status line. -prfc num specifies the number num of the color of the text of a prompt. -prbc num specifies the number num of the color of the background of a prompt. -q1fc num specifies the number num of the color of the text of level one of quoted text. -q1bc num specifies the number num of the color of the background of level one of quoted text. If the option -q1bc is used, the default value of this option is the background color or normal text. -q2fc num specifies the number num of the color of text of level two of quoted text. -q2bc num specifies the number num of the color of the background of level two of quoted text. If the option -q1bc is used, the default value of this option is the background color or normal text. -q3fc num specifies the number num of the color of text of level three of quoted text. -sbfc num specifies the number num of the color of text of signature block text. -sbbc num specifies the number num of the color of the background of sig- nature block text. Bugs The manner in which lines longer than the display width are dealt is not immediately obvious. Lines that continue beyond the edge of the display are indicated by a '$' character at the end of the line. Long lines are scrolled horizontally as the cursor moves through them. Files pico.save Unnamed interrupted work saved here. *.save Interrupted work on a named file is saved here.
