french-deconjugator - analyze conjugated French verbs


echo aimé | french-deconjugator > result.txt


french-deconjugator reads conjugated French verbs from the command line or from standard
input and writes (to standard output) the verb's infinitive form, the mode (infinitive,
indicative, conditional, subjunctive, imperative or participle), the tense (present, past,
imperfect, future), the person (1, 2 or 3, while 0 is used for the present participle
tense, and 4 and 5 are used in the past participle tense), and the number (singular or
plural). These fields are separated by a comma and a space.

The standard input is not read if verbs are passed as command-line arguments.

By convention, persons 4 and 5 are used in the past participle tense to indicate the
gender: 4 means masculine (e.g., "aimé" or "aimés") and 5 means feminine (e.g., "aimée" or

A single conjugated form can correspond to more than one mode, tense and person. In this
case, each alternative is written on its own line.

In all cases, the end of the answer is marked by an empty line. If the word is unknown,
only this empty line is written. The names for the mode, tense and number are always in
English. (This is meant to facilitate automatic parsing of the output. For a French user
interface, see the GNOME application and applet.)

The command flushes its output buffer after finishing each answer. This allows the
command to be easily called from another program through two pipes.

The command starts by loading its database from XML files (stored typically in
/usr/share/verbiste). This takes some time, so it is a good idea to have the command
answer many requests instead of running it for each request.

The verbiste library's source archive contains Perl and Java example programs that
illustrate this technique.

This commands expects to read Latin-1 characters and writes Latin-1 characters. There
must not be any leading or trailing white spaces on the lines read by the command.
