Commit time, a Python Command-Line Utility

Please see Warnings and State of Development below.

Be sure to check out the wiki. There is a cookbook section. Also check out, which is readable using Freeplane.

This is a script aspriring to be in this category:

I wrote over 800 org files, which reside on my local disk. They consist of simple notes with links to websites and other files on local disk. Broken links would naturally occur as I made changes to files on local disk. Files for some of my favorite subjects would gradually become full of broken links, leaving me unable to make more notes. I could not find a solution online. I am an amateur who has been spending some time learning python, but still has a lot to learn, and this project seemed like the next thing to try.

I have read almost zero org mode documentation. I use org mode to keep simple notes, and am mostly interested in quickly looking up information in my collection of org files. When links are broken, my org files greatly diminish in usefulness.

The goals of this script:

  1. repair links (inside an org file) to files on local disk

  2. Optionally add a header to an org file; this header is a list of incoming links, outgoing links, and tags. This feature is off by default.

The script is a command line utility to be used in the terminal. Currently it is known to run in the Ubuntu OS only. Display its help message:

python -h

Warnings and State of Development

WARNING this python script is amateur work

WARNING bugs are still regularly appearing. Comprehensively testing this code is not easy; there is now a test script: First run the test script. If it finds a problem, fixing that problem is recommended before operating on your files.

WARNING can screw up your files. Please first backup your files.

WARNING does not recognize all possible org file characteristics and may trample them (backup first; dry run mode first)

WARNING org mode in emacs can change and this script can break as a result

WARNING intended for experienced users only

WARNING tags that are all caps are changed to all lowercase; if you know python, this is easy to change

The script is amateur work that overwrites files on your local disk. If you are not ready, willing, and able to restore all your files from backups, don't run this.


WARNING only known to work in Ubuntu 14.04, with default bash

recommended but optional: set up a virtual environment (

emacs 24.3.1 and org mode 7.9.3f

Python 2.7.6

Python add-ons:

pudb (debugger) not required, but useful; script has a flag to run it.

Getting Help

In terminal, typing python -h prints the usage message:

`Before running on your org files, first run, and resolve any errors it reports

example of running
python -O -uD -f /home/userName/Documents/ -N 20 -t 300

flags with no input argument:
-h, --help: show this help blurb
-H, --addHeader: add a header to org files; default is to not add a header to any org file
-u, --userFixesLinks: when automatic link repair fails and it makes sense to do so, prompt user to fix broken links manually (menu-driven)
-n, --noSpideringStopViaKeystroke: normally spidering can be stopped via typing anything then hitting enter key; -n disables this.  also set by -d.
-d, --debug:  run script in pudb.  additionally sets -n.
-D, --dryRun:  make no changes to org files on disk.  make a copy of database and make changes to the copy.
-l, --showLog:  display log file in terminal after operating on each org file; this gives user time to inspect a rewritten org file in dry run mode before the file is reverted to original
-b, --noBackup: do not make .bak copy of each org file before replacing it on disk
-q, --quickMode: when a file has been recently spidered, just look up outward links in database and move to next file to spider, rather than making full representation, repairing links, etc;  intention is to speed things up

flags that require input argument:
-f, --inputFile:  supply a file to begin spidering; if no -f, all org files in /home/username/Documents (default) are walked; see also -F, --folderToSpider
-L, --loggingLevel:  logging to take place above this level.  valid inputs: None, debug, info, warning, error, critical;  default value None
-N, --maxFilesToSpider:  max number of files to spider, an integer
-t, --maxTimeToSpider: max time to spend spidering (seconds)
-F, --folderToSpider: specify a folder to spider in (will spider in this folder and subfolders recursively); default is /home/username/Documents

useful python flags:
python -O:  -O flag turns off assert statements in the script  Assert statements identify associated preconfigured error conditions.  Suppressing them via -O flag speeds up script execution.
At current state of development of, it is recommended to not use the -O flag.

files that affect the behavior of
pastInteractiveRepairs.csv: contains data from past runs of in which a user interactively repaired broken links

orgFilesDryRunCopy.sqlite, orgFiles.sqlite: sqlite database used by

.OFLDoNotSpider: each line is a pattern corresponding to files or folders that will not be spidered.  Each line is interpreted to match files/folders on disk using the Python module glob.glob.
Any folder will blacklist all files whose path contains that folder.

.OFLDoNotRepairLinks:  same as .OFLDoNotSpider, but broken links to matching files/folders will not be repaired.  Also, the matches will not be used to repair broken links.`

For further details, please check out the wiki.

Configuring; Settings

Search inside for comments that include the text 'setting'

Blacklisting for spidering and repairing links is essential since many users will have a subset of their files that they do not want to modify. To control blacklisting, create configuration files .OFLDoNotSpider, .OFLDoNotRepairLinks. Each line is interpreted using glob.glob: see a PyMOTW article.

Example configuration file contents:

# this is a comment



# /home/userName/Documents/Computer

# /home/userName/Documents

There are further blacklisting controls inside, primarily two lists of individual folder names (e.g. 'env', 'venv') for blacklisting; find them via text search for 'setting.'


There is no question that this script will improve given further development. It does run on my machine, but bugs appear regularly.

Boilerplate from

  1. Fork it!

  2. Create your feature branch: git checkout -b my-new-feature

  3. Commit your changes: git commit -am 'Add some feature'

  4. Push to the branch: git push origin my-new-feature

  5. Submit a pull request :D

I am a beginner with Github. I make no promises in terms of maintaining anything. The phrase 'the code is free, people are not' applies. You can at least fork. If I can comprehend your changes (far more likely if sufficiently documented), I am much more likely to accept a pull request. A test in the test script should be written for any nontrivial change. Submissions must respect intellectual property rights of work they are derived from (e.g. citing stackexchange).

I put this project on Github because it would make me happy if someone found it useful. It would be exciting to see a better programmer improve on it. There is nothing promised here except for the free code.


This is an amateur python script originally developed by the github user cashTangoTangoCash.

The script contains comments which credit sources of code snippets found on e.g.


GNU General Public License v3.0

See: LICENSE.txt


Particularly helpful:

The free online book Python for Informatics Exploring Information by Severance: the Twitter spidering example in Ch 14 provided the idea for this script.

The Gauld Tutorial

I am highly aware that I did not read and understand everything, and have much more to learn.


Fix or repair certain broken links in an emacs org mode org file. An amateur python script; handle with caution.
