NAME
desed - TUI debugger for sed scripts
SYNOPSIS
desed |
[OPTIONS] SED_SCRIPT INPUT_FILE |
DESCRIPTION
desed is a command line tool with beautiful TUI that provides users with a comfortable interface and a practical debugger, used to step through complex sed scripts.
OPTIONS
As desed operates by running sed internally, instead of connecting to a "live" instance, some of the program options are used to control the behaviour the internal sed instance.
sed options
- -n, --silent, --quiet
- Suppress automatic printing of pattern space.
- -E, --regexp-extended
- Use extended regular expressions in the script.
- --sandbox
- Operate in sandbox mode (disable e/r/w commands).
- -z, --null-data
- Separate lines by NUL characters.
desed options
- -v, --verbose
- This will enable various debug printing to stderr.
- --sed-path EXECUTABLE
- Instead of the system-wide sed install, use EXECUTABLE instead.
CONTROLS
- j, k, g, G
- Movement, just as in vim.
- b
- Toggle breakpoint.
- s, a
- Step forward / backwards.
- r
- Run to next breakpoint or end of script.
- R
- The same as r, but backwards.
- l
- Reload code and continue debugging in the same place as before.
- q
- Quit.
Similar to vim, most commands can be prefixed with numbers. The mouse can also be used to scroll through the script and toggle breakpoints.
BUGS
Report all bugs at https://github.com/SoptikHa2/desed. I know about the bugs that happen when sed script contains newlines. Sed parsing that causes this is currently under rewrite.
