FreeBSD Manual Pages
PSPG(1) pspg manual PSPG(1) NAME pspg - Postgres Pager Everybody who uses psql also uses the less pager. Which, while it works well, has no special support for tabular data. I found a few projects, but none was good enough for this purpose. Thus I decided to write a small specialized pager to use as a psql pager. This pager can be used from the following command line clients, too: O mysql O sqlite O pgcli https://github.com/dbcli/pgcli/ O monetdb O Trino (formerly Presto SQL) https://trino.io/ O usql https://github.com/xo/usql/ O sqlcl https://github.com/okbob/pspg/#sqlcl (for oracle) O nushell https://www.nushell.sh/ Main target O ability to freeze the first few rows, or first few columns O ability to sort data by the specified numeric column O ability to use fancy themes - like mcview or FoxPro - http://ok- bob.blogspot.com/2019/12/pspg-themes-what-you-use-it.html O mouse is supported and used O ability to copy a selected range to the clipboard Video presentation https://www.youtube.com/watch?v=JyxuEkoYDQk Screenshots Options [pavel@localhost ~]$ pspg --help pspg is a Unix pager designed for table browsing.

The custom theme file should be saved in directory with pspg configuration. The name of this file should be .pspg_theme_xxx. The custom theme can be selected by command line op- tion --custom-style=name or by command \ctheme name. Example of a custom theme file (named .pspg_theme_mc2 (it can be acti- vated by command \ctheme mc2)): template = 1 template_menu = 3 background = black, white data = black, white label = black, white, italic, bold border = #000000, white footer = lightgray, white cursor_data = blue, white, italic, bold, dim, reverse cursor_border = blue, blue , italic, bold, dim, reverse cursor_label = blue, white, italic, bold, dim, reverse cursor_footer = blue, white, italic, bold, dim, reverse cursor_bookmark = red, white, italic, bold, dim, reverse cross_cursor = white, blue, italic, bold cross_cursor_border = brightblue, blue status_bar = black, lightgray title = black, lightgray scrollbar_arrows = black, white scrollbar_background = lightgray, white scrollbar_slider = white, gray Some keys can be marked by symobol *. Marked keys are used for odd records. data* = black, lightgray label* = black, lightgray, italic, bold border* = #000000, lightgray template and template_menu set fallback values for any keys not speci- fied in the custom theme. template_menu in particular is currently the only way to customize the F9 menu appearance.

symbol: \copy csv | less Ending The pager can be ended by pressing keys q or F10 or Esc 0. With option --on-sigint-exit then the pager is closed by pressing keys Ctrl+c or Esc Esc. Use <kbd>Escape</kbd>, key instead <key>Alt</key> + <key>key</key> pspg supports a possibility to use a sequence of keys Esc, key instead an combination of Alt+key. The interval between pressing Esc and key is limmited by interval specified by option esc-delay or by configura- tion's option esc_delay. This is max delay time in ms. After this in- terval, the single pressing Esc is interpreted as Escape. -1 meas un- limited, 0 disables this feature. Column search Column search is case insensitive every time. Searched column is marked by vertical cursor. Last non empty string searching pattern is used when current searching pattern is empty string. Searching is starting after visible vertical column or on first visible not freezed columns (after some horizontal scrolling) or on first column. After last column searching starts from first again. Export & Clipboard For clipboard support the clipboard application should be installed: 1. wl-clipboard (Wayland), 2. xclip (xwindows) or 3. pbcopy (MacOS). pspg try to translate unicode symbol '' to NULL every time. If you don't use special setting by \pset null ..., then psql displays empty string instead NULL. pspg hasn't any special detection (in export rou- tines) for this case. You should to check and enable or disable menu item Empty string is NULL. pspg has automatic detection of clipboard application. Unfortunatelly, this detection should not to work for same cases. You can specify the application by specify number (1,2,3) to --clipboard-app option. Status line description O V: [d/d d..d] - vertical cursor: (column number)/(columns) (char possitions from) .. (char possitions to) O FC: d - freezed columns length in chars O C: d..d/d - unfreezed visible data in chars (from .. to)/(total) O L:[d + d d/d] - lines (number of first visible line) + (number of line of display), (current line)/(lines) O d% - percent of already displayed data Usage as csv viewer It works well with miller http://johnkerl.org/miller/doc/index.html mlr --icsv --opprint --barred put '' obce.csv | pspg --force-uniborder New version has integrated csv support - just use --csv option. It can be integrated into mc O copy file from /etc/mc/mc.ext to your ~/.config/mc directory O insert there ##csv regex/\.csv View=pspg -f %f --csv O restart mc Known issues O When you use pspg on Cygwin, then some temporary freezing of scrolling was reported In this case, please, use an option --no-sleep. I see slow scrolling (via scrollbar) inside konsole (KDE terminal). The option --no-sleep helps too. Usage in watch mode The result of query can be refreshed every n seconds. pspg remembers cursor row, possible vertical cursor, possible ordering. The refreshing should be paused by pressing space key. Repeated pressing of this key enables refreshing again. pspg uses inotify API when it is available, and when input file is changed, then pspg reread file immediately. This behave can be disabled by option --no-watch-file or by specification watch time by option --watch. Streaming modes pspg can read a continuous stream of tabular data from pipe, named pipe or from file (with an option --stream or it can read a stream of queries from pipe or from file (with an option --querystream). In stream mode, only data in table format can be processed, because pspg uses empty line as separator between tables. The query stream mode is an sequence of SQL statements separated by char GS (Group separator - 0x1D on separated line. Recommended psql configuration you should to add to your profile: #for Postgres 10 and older export PAGER="pspg" #for postgres 11 and newer export PSQL_PAGER="pspg" #or "\setenv PAGER pspg" to .psqlrc and .psqlrc \set QUIET 1 \pset linestyle unicode \pset border 2 \pset null \unset QUIET some possible configuration: -- Switch pagers with :x and :xx commands \set x '\\setenv PAGER less' \set xx '\\setenv PAGER \'pspg -bX --no-mouse\'' :xx LC_CTYPE should be correct. Mainly when you use unicode borders. ncurses doesn't display unicode borders (produced by psql) without cor- rect setting of this variable. Is possible to check a value 'C.UTF8'. Attention When you use a option --only-for-tables, then O set PAGER to pspg and PSQL_PAGER to less or O set PAGER to less and PSQL_PAGER to pspg MySQL usage MariaDB [sakila]> pager pspg -s 14 -X --force-uniborder --quit-if-one-screen PAGER set to 'pspg -s 14 -X --force-uniborder --quit-if-one-screen' MariaDB [sakila]> select now(); MariaDB [sakila]> select * from nicer_but_slower_film_list limit 100; SQLite SQLite native client doesn't produce well formatted output, but can be forced to generate CSV format - and this format is well readable for pspg sqlite3 -csv -header testdb.db 'select * from foo2' | pspg --csv --csv-header=on --double-header pgcli pgcli https://github.com/dbcli/pgcli/ needs the following configuration options (~/.config/pgcli/config): pager = /usr/bin/pspg --csv --rr=2 --quit-if-one-screen --ignore-case --csv-header on --pgcli-fix table_format = csv Older version of pgcli had very slow output in tabular format. An workaround was using csv format. This should not be necessary on cur- rent versions when the performance issue was fixed. An option --pg- cli-fix fixed import of partially broken csv format generated by pgcli. Modern version of pgcli doesn't need csv format, and doesn't need --pg- cli-fix option. pager = /usr/bin/pspg --rr=2 --quit-if-one-screen --ignore-case sqlcl As sqlcl doesn't currently support a pager option directly, you can ei- ther use a tool like qsh https://github.com/muhmud/qsh to work around this issue, or use the pspg.sql https://github.com/okbob/pspg/blob/mas- ter/scripts/sqlcl/pspg.sql script from this repo. To use the script, start sqlcl as shown below (it's important to pass in the details of your current tty): $ TTY=$(tty) sqlcl system/system @/path/to/pspg.sql You can now have the results of a query sent to pspg like this: SQL> pspg select * from user_tables; nushell The pspg supports default table_mode: rounded and table_mode: heavy. The conversion to csv can be used too. sys | get cpu | to csv | pspg --csv Note: footer_mode should be disabled Note - mouse pspg try to use xterm mouse mode 1002, when terminal and ncurses are not too antique. If there are problems with usage - unwanted visual artefacts when you move with mouse when some mouse button is pressed, then 1. please, report issue (please, attach log file), 2. use an op- tion --no-xterm-mouse-mode and pspg will not try to activate this mode. Note - true color themes on KDE konsole terminal On my Fedora this terminal doesn't correctly display true color themes. The basic problem is in default TERM setting, that is xterm-256color. Unfortunately, the konsole terminal is not fully compatible with xterm, and doesn't allow color changing. You can force direct colors by using the option --direct-color or by setting TERM=xterm-direct. Second op- tion is more corect setting of TERM variable to konsole-256color. In this case the pspg will map the true rgb colors to supported 256 col- ors. Note - compilation issue Some linker issues can be fixed by: I changed gcc -lncursesw pager.c -o pspg -ggdb to gcc pager.c -o pspg -ggdb -lncursesw If you want to use pspg as Postgres client, then you need run configure --with-postgresql=yes. On Fedora with own Postgres build I had to in- stall openssl-devel package and I had to set export PKG_CON- FIG_PATH="/usr/local/pgsql/master/lib/pkgconfig/". On FreeBsd you should to use gmake instead make. Note - Installation When you compile code from source, run ./configure first. Sometimes ./autogen.sh first If you would to display UTF-8 characters, then pspg should be linked with ncursesw library. UTF-8 characters are displayed badly when li- brary ncursesw is used. You can see broken characters with incorrect locale setting too. You can check wide chars support by pspg --version. Row ncurses with wide char support is expected. Re-run configure with --with-ncursesw option. When this command fails check if development package for ncure- sesw library is installed. Homebrew (for Linux & MacOS) # brew install pspg Debian # apt-cache search pspg # apt-get install pspg Fedora (28 and later) # dnf install pspg RPM (CentOS/openSUSE/) The pspg is available from community repository https://yum.post- gresql.org/packages.php Alpine Linux # apk add pspg Gentoo # emerge -av dev-db/pspg Arch Linux The Arch User Repository contains two versions: O pspg https://aur.archlinux.org/packages/pspg/ is a fixed release. O pspg-git https://aur.archlinux.org/packages/pspg-git/ tracks the master branch. Use the AUR helper of your choice or git and makepkg to install pspg. FreeBSD # pkg install pspg OpenBSD # pkg_add pspg More about it https://fluca1978.github.io/2021/10/28/pspgOpenBSD.html Using MacPorts (MacOS only) # port install pspg Solaris There are few issues requires manual code changes for successful compi- lation - we successfully tested pspg, but although pspg was linked with ncursesw libraries, the utf8 encoding support didn't work fully cor- rectly - probably due some issues in libc library. There are problems with chars encoded to 3bytes - unicode borders, .. Two bytes unicode chars should be displayed well. You can use pspg with usual accented chars, but unicode bordes should not be used. Replacement ascii borders by special borders chars (by ncurses technology) works well - looks on Options|Force unicode borders option. O Solaris make doesn't support conditional statements - should be re- moved So, remove unsupported functionality from Makefile (ifdef,en- dif), replace -include by include first. O After running configure remove link on termcap library from con- fig.make. It is garabage produced by readline automake script. Com- bination with ncurses libraries makes some linking issues. builtin libraries export CURSES_CFLAGS="-I/usr/include/ncurses/" export PANEL_LIBS="-lpanelw" ./configure OpenCSW development export CFLAGS="-m64 -I/opt/csw/include" export LDFLAGS="-L/opt/csw/lib/64 -R/opt/csw/lib/64" export PKG_CONFIG_PATH="/opt/csw/lib/64/pkgconfig" ./configure Possible ToDo O Store data in some column format (now data are stored like array of rows). With this change can be possible to operate over columns - hide columns, change width, cyclic iteration over columns, change order of columns, mark columns and export only selected columns (selected rows).
